tft display eyes pricelist

The Snake Eyes Bonnet is a Raspberry Pi accessory for driving two 128x128 pixel OLED or TFT LCD displays, and also provides four analog inputs for sensors.

It"s perfect for making cosplay masks, props, spooky sculptures for halloween, animatronics, robots...anything where you want to add a pair of animated eyes!

This product doesn"t include two displays or connector cables! You"ll want 1 or 2 of either the Adafruit 1.44" TFT Breakout or the Adafruit 1.5" OLED Breakout. The OLED looks better with higher contrast and viewing angle, but is more expensive. You"ll also want a bunch of 12" F-F jumper cables to connect your displays. Soldering is required to attach headers onto the Bonnet and displays, so make sure you have a soldering iron, solder and some basic hand tools.

If you want to make it your self then Let’s start the tutorial, So you can make it in an easy way with an ESP8266, TFT display, and other few components.

Arduino nano RP2040 has fast SPI so it can work to run a uncanny eye on TFT display. you can use this board and adafruit libraries to connect this board, visitadafruit pagefor more details but for now we are using wemos D1 mini board.

TFT stands for thin-film-transistor liquid-crystal display. It is a variant of a liquid-crystal display (LCD) that uses thin-film-transistor (TFT) technology to improve image qualities such as addressability and contrast.

If your driver is successfully installed then you are ready to program the Wemos D1 mini-board, But before uploading the Code firstly install the “TFT_eSPI” library.

OpenArduino IDEand go to theSketch >> Include Library >> Manage Librariesand here type “TFT_eSPI” and hit enter. Now scroll down you will see the library, install the latest version of the library.

Now you will see an Uncanny Eye on your TFT screen as shown in the image, if your screen is still blank then check the connection, if still your screen is blank try to connect it with Arduino Uno but remember to connect 1k resister on each pin because Arduino Uno works on 5V logic but TFT works on 3V3 logic.

Now TFT with Wemos D1 mini board is working fine but it is working with the USB supply via Computer or laptop. We need to make it more portable so we can easily carry it and take it where we want.

If you have noticed there is a 330ohm resistor connected on the D2 pin, this is because the 134N4p module requires a minimum of 60mA current draw to wake up continuously, it currently does not reach 60mA it will restart. So I connected this resistor on this D2 pin and it will be high when code is running on the Wemos board. The total current of Wemos board and TFT is 50mA so I connected this 330 resistor and because the pin can give 3.3v output the current draw across the resistor is 10mA, the overall current is 60mA so 134N3P module will not shut down in the middle of it still getting restart just decrease the resistance value.

Take your 3D print, but make sure it is fully dry. First of all, put TFT inside the front section of the 3D print which has a hole. Put some hot glue to make it stable in place.

I inserted the battery just behind the TFT display and the Wemos module behind the 134N3P module, you will see some different setups in the image, what was wrong I have changed it later but forgot to take pictures.

Give your next animatronic or robotic project the gift of eyes with this Snake Eyes Bonnet Pack for Raspberry Pi. The Snake Eyes bonnet is an accessory for driving TFT LCD displays, and it also provides four analog inputs for sensors. It"s perfect for making cosplay masks, props, spooky sculptures for halloween, animatronics, robots...anything where you want to add a pair of animated eyes!

We recently added some very fancy 1.54" TFT displays with high density 240x240 resolution and IPS full angle viewing. Basically, they"ve got the image quality of an OLED, but the pricing of a TFT - and 4x the pixels of either! Perfect for dazzlingly good looking eyes. What"s not to love?

We really really recommend only pairing this with a Raspberry Pi 3. These high-density displays have a lot of pixels to push around and the quad-core Pi 3 will help keep the frame rate high and flicker-free. You can use a 3 Model B or 3 B+.

Whether it is for professional graphic designing, gaming, or general computing requirements, a high-quality monitor can deliver an engaging viewing experience. Available in a wide range of options, these devices offer you the flexibility to choose the one as needed. You can decide based on their size, screen resolution, panel type, display type, and technology. You can also choose based on their design and mounting, webcam, and additional features. So, whether you are bored of your old monitor or need an upgrade to take advantage of the sophisticated software, you can browse and find the right screen for your requirements. Several brands, such as Dell, Acer, LG, HP, BenQ, and many more offer a myriad of options to choose from.

You can go ahead with a basic monitor if you only need it to get you through the day and help you send emails, post on social networks, surf the web, pay bills, watch films, and so on. For these uses, adequate-size screens with full HD displays are easily available. Heavy games demand displays with high resolution, a good response time, a fast refresh rate, and a wide viewing angle of up to 178 degrees or more. And, if you are a gaming enthusiast, you can search for AMD FreeSync or NVIDIA G-Sync technology for an engrossing gaming experience. Some gamers also search for two gaming monitors or a truly widescreen display to enjoy an enhanced view. For photographers, graphic designers, animators, coders, and other multimedia specialists, widescreen displays with Full HD or Quad HD resolution can be suitable. The IPS panel and other display technologies provide wide viewing angles and excellent colour accuracy. You will also need to think about response time, mounts, stands, and so on for an improved viewing experience. If you want to buy this device for work, such as working on spreadsheets or collaborating with coworkers, an LED or IPS display with Full HD resolution will be ideal.

If you want to enjoy high-quality pictures, you need a display with up to 1920x1080p Full HD display and more. But, a QHD or up to 4K variant will deliver more sharp and clear images. As far as the size is concerned, up to 81.28 cm (32) devices are enough for viewing from average desktop distances. You can find up to 81.28 cm (32) 4K gaming or general use displays. The refresh rate, which is measured in hertz, indicates how many times your display updates with new information every second (Hz). A large number delivers smooth images. Gamers desire a display with a refresh rate of at least 75 Hz as well as the shortest response time possible. But, if you are not a gamer, a refresh rate of 60 Hz should suffice. Curved displays are less eye-straining and have a large field of view. And, these displays are often wide, which indicates high performance. So, you can buy monitors online and enhance your overall viewing experience.

This cap is an accesory for Raspberry PI which can drive two screens 128 x 128 pixel OLED or TFT and which allows to provide 4 analog inputs for sensors. It is ideal to create masks for your animatronics or cosplay or to give some humanity to your robots.

When we purchase a new smartphone we go through a list of specifications that includes the processor, software, cameras, display type, battery, etc. The display of the smartphone is something which has always been a concern for people. And smartphone technology has advanced so much in the past decade that you get several display technology options to choose from.

Today, a smartphone is not just a means to send and receive calls and texts. It has become a general necessity, so choosing the right technology should be your main priority. Coming back to displays, as we said there are plenty of display types available right now.

Two of the main contenders for display technologies that are widely available are AMOLED and LCD. Here in this article, we will be comprising AMOLED vs LCD and find out which one is better for you.

Starting with the AMOLED first, it is a part of the OLED display technology but with some more advanced features. To completely know about it must understand its all three components. The first one is LED, “Light Emitting Diode”. Then we have “O” which stands for organic and makes the OLED.

The AMOLED display is similar to the OLED in various factors like high brightness and sharpness, better battery life, colour reproduction, etc. AMOLED display also has a thin film transistor, “TFT” that is attached to each LED with a capacitor.

TFT helps to operate all the pixels in an AMOLED display. This display might have a lot of positives but there are a few negatives too let’s point both of them out.

A major issue with these displays is of burning of pixels. After showing a specific image or colour for a longer period of time, the pixel can get burned. And if there is a problem with a single pixel it will affect the entire display.

Low outdoor visibility, usually the AMOLED Displays are quote not bright in direct sunlight and outdoor readability could be a problem for some devices but average screen brightness.

The LCD stands for “Liquid Crystal Display”, and this display produces colours a lot differently than AMOLED. LCD display uses a dedicated backlight for the light source rather than using individual LED components.

The LCD displays function pretty simply, a series of thin films, transparent mirrors, and some white LED lights that distributes lights across the back of the display.

As we have mentioned, an LCD display always requires a backlight and also a colour filter. The backlight must have to pass through a thin film transistor matrix and a polarizer. So, when you see it, the whole screen will be lit and only a fraction of light gets through. This is the key difference comparing AMOLED vs LCD and this is what differentiates these two display technologies.

The LCD displays are cheaper compared to the AMOLED as there is only one source of light which makes it easier to produce. Most budget smartphones also use LCD displays.

LCD displays have bright whites, the backlight emits lots of light through pixels which makes it easy to read in outdoors. It also shows the “Accurate True to Life” colours, which means it has the colours that reflect the objects of the real world more accurately than others.

LCDs also offer the best viewing angle. Although it may depend on the smartphone you have. But most high-quality LCD displays support great viewing angles without any colour distortion or colour shifting.

The LCD displays can never show the deep blacks like AMOLED. Due to the single backlight, it always has to illuminate the screen making it impossible to show the deep blacks.

The LCDs are also thicker than other displays because of the backlight as it needs more volume. So, LCD smartphones are mostly thicker than AMOLED ones.

Both of these display technologies have their own Pros and Cons. Taking them aside everything ends up with the user preferences as people might have different preferences among different colours and contrast profiles. However, a few factors might help you to decide which one fits perfectly for you.

Let’s start with the pricing. Most AMOLED display smartphones always cost more than an LCD smartphone. Although the trend is changing a bit. But still, if you want to get a good quality AMOLED display you have to go for the flagship devices.

The colors are also very sharp and vibrant with the AMOLED displays. And they look much better than any LCD display. The brightness is something where LCDs stood ahead of the AMOLED display. So using an LCD display outdoors gives much better results.

The last thing is battery consumption, and there is no one near the AMOLED displays in terms of battery. As of now, all smartphones feature a Dark Mode and most of the apps and UI are dark black with a black background. This dark UI on smartphones doesn’t require any other light, it gives the AMOLED displays a boost in battery performance.

Looking at all these factors and comparing AMOLED vs LCD displays, the AMOLED displays are certainly better than the LCDs. Also, the big display OEMs, like Samsung and LG are focusing more the OLED technologies for their future projects. So, it makes sense to look out for AMOLED displays. That being said, if we see further enhancements in the LCD technology in terms of battery efficiency and more, there is no point to cancel them at this moment.

Due to the human eye is used 3D stereo images in daily life, therefore, that including movies and other displays is shown in the picture should also be stereo images, amazing, however this unconscious needs, but for a long time because of the constraints on science and technology, fast and there’s no resistance to accept, two-dimensional images. After the digital information revolution, in addition to promoting the early arrival of multimedia society, it also reignited the urgent demand for three-dimensional images in the fields of medicine, animation, CAD/CAM, and so on. In view of this, this paper will introduce the trend of using LCD to produce a 3D images.

Japanese SANYO company is the earliest engaged in studies of three-dimensional imaging technology, as early as in 94 launched without special glasses 3D image segmentation, using the image segmentation can be used to view and admire the three-dimensional dynamic images, basically it is according to the principle of parallax barrier make video interaction first arranged by slender columns grating by two eyes capture after observation, due to the longitudinal image into the left and right eye due to the parallax barrier separated, left and right eye images captured by the small deviation, finally read through the retina as a three-dimensional image.

Use this kind of principle to be able to be aimed at the most appropriate position when seeing a picture, in addition, to provide the eye shadow image of the left and right of the viewer, from the image front display area to the area covered by the optimal distance, for the viewer to become a normal stereo 3D image. However, images adjacent to the two eyes will be unconsciously captured and read by the left and right eyes to form the so-called reverse field of vision. In other words, viewers using this 3D image segmentation must be fixed at a certain viewing position to produce stereoscopic vision.

In order to improve the lack, therefore, developed the head detection system, using this detection system can detect view at any time the head position, once produce inverse visual field monitor switch immediately around eyes read by image, so that not only can prevent the occurrence of the inverse apparent problem but can also enlarge the three-dimensional stereo images of considerable scope.

However, in the actual use of the upper head detection system, it was found that the interfaces in each diamond area were non-long and narrow, resulting in poor viewing performance, such as subtle overlapping images, distortion, and black vertical stripes, and easy eye pain and fatigue. Given this SANYO change the system to constitute by the liquid crystal electronic drive head detection system of movable type, if the scanning head moving to the interface area, the new test system can immediately test the head, and to move the opening of a three-dimensional image segmentation, which means it is using the detector to detect and monitor view of head position and will feedback the detection result to the image segmentation, adjustment and control is shown on the LCD display the image of the left and right eyes position, take advantage of this new technology view and who can watch to a wide range of three-dimensional stereo images.

The biggest drawback of the above electron-driven LCD head detection system is that the viewing distance (the distance from the screen of the display to the viewer) in the stereo viewing area still exists, so it is greatly limited in application. In order to shorten the viewing distance and expand the application field, a new generation three-dimension display is developed. The new display features:

Traditional 3D image display without special glasses, the same horizontal direction of the small picture before and after the stereo visual range is larger than the big picture stereo visual range, this is because the small picture perspective is relatively small, LCD and image segmentation is less likely to produce the so-called moire interference. This physical phenomenon is used to divide the LCD display and the image divider into 16 equal parts by electronic means to control the exclusive area.

In other words, it can adjust the opening position of the image splitter and the image in the LCD display to the most appropriate state according to the viewer’s position, so that no matter the stereoview is far or near, the viewer can see the three-dimensional stereo image. Based on the LCD display at the top of the 3D view of the heat detection system that detects the secondary yuan location data (or so) before and after, at the same time control switch and LCD display left and right eye image, and image segmentation opening position, for the stereoscopic view area outside of the view, is to control the individual image segmentation, the results before and after the direction of the stereoscopic view area more than three times bigger than ever before.

In the past, the parts outside the stereoscopic viewing area of the display are prone to waviness, distortion, or local reversed-vision problems, resulting in easy eye fatigue and difficulty in viewing stereoscopic images. The new electronic image divider and LCD display can monitor the condition of the viewer at any time to maintain the most appropriate stereo viewing position.

As long as the shutter of the electronic-driven LCD is turned off, the second-element image of the same quality as the general flat display can be obtained.

At present, 3D image display is mainly applied in the work staTIon, cartoon and other animation production, medical use, educational use, aviation, automobile simulation teaching, electronic game instrument, and other fields. Examples include stereoscopic endoscopy, stereomicroscope, surgery using guidance system, medical diagnosis using CT, MRI, visual function examination, medical education, medical training, etc.

The working principle of stereo LCD display conclusion: Although the new generation of 3d stereoscopic displays addresses many of the drawbacks and greatly increases the viewing range, they also face practical challenges such as low consumer awareness, high prices, and the ability to only use one person. As for the problem of single users, we have drawn up a plan to explore and develop a multi-dimensional display for multiple users. Besides, precision, mass production, and control of ripples are also projects to be overcome. It is expected that in the future, the market of 3D images will expand with the progress of software and hardware technologies, which means that it is more important to keep abreast of the fluctuations of the market and timely provide relevant technologies.

TFT stands for Thin-Film Transistor. TFT technology is a new standard these days for manufacturing displays, monitors, laptop screens, and other devices. TFT LCD displays can show crisp text, vivid colors, fast animations, and complex graphics.

TFT LCD monitors, also called flat panel displays, are replacing the old style cathode ray tubes (CRTs) as the displays of choice. Almost all LCD monitors today take advantage of the TFT technology.

Each pixel on a TFT display is backed by a tiny transistor. Transistors are so small these days, they need only a very minimal charge to control what they do. TFT displays are much more energy efficient than regular CRT screens that need a powerful light source.

TFT displays also allow for very fast re-drawing of the display, so the image has very little chance to flicker. This was not always the case with flat-panel monitors. Original passive matrix LCD displays were not able to refresh at very high rates and therefore could not keep up with fast moving images. A TFT monitor refresh rate is very high resulting in a display that can be used for video, gaming, and all forms of multimedia.

A TFT monitor delivers crisp text, vibrant colors, and an improved response time for multimedia applications. Today"s standard for response rate in TFT monitors is 16 ms or less.

In general, a LCD display comprises of a layer of LCD material and one or more polarizing layers made of plastic, glass, or some other material. A LCD display has a sandwich-like structure with liquid crystals filled between two glass (or plastic or polycarbonate) plates.

These liquid crystals when stimulated by an external electrical charge can change the properties of light passing through them. When you align two polarizing materials with each other, light passes through. When you align one polarizing agent at a 90° angle to the other, light is blocked. Change the voltage, and the amount of light passing through the display is changed.

A TFT display is an advanced LCD display. A TFT monitor uses so-called thin-film transistor technology to project a picture on the screen. Transistors in a TFT display are used to change the orientation of the polarizing agent.A typical 17-inch TFT monitor has about 1.3 million pixels and 1.3 million transistors. The following text explains TFT in a greater detail...

Passive LCD panels cannot quickly change the orientation of the crystal. Well, it is quick, but not quick enough to display fast-moving graphics. To overcome this slowness, engineers came up with active-LCD technology. Active-LCD displays use transistors to actively change the orientation of crystals. That is where TFT comes from. T in TFT for transistor. This method allows for faster control of the LCD cell but is also more complex.

While passive-LCD displays start to blur with images moving faster than 8 to 15 frames/sec, TFT displays can display full-motion video and graphics because they use fast switching transistors.

Now that we know how a LCD works and what it behind TFT, we can start talking about color. Each pixel in a color TFT LCD is subdivided into three subpixels. One of the subpixels is capable of producing red, the other one green, and the last one blue color. Red, green, and blue are the basic colors. Any other color can be produced by mixing up these three. One set of RGB subpixels is equal to one pixel.

Old TFT displays and the small ones in simple applications such as calculators are reflective TFT. A reflective TFT display has no backlight. The polarizing agent at the rear of the TFT display is simply a mirror layer behind the TFT panel. The agent merely reflects incoming light from the front of the display. You need to be in a well-lit room to be able to read this type of display.

The next step in a TFT LCD design was to add a light source to it. More advanced TFT displays have added sidelights or front lights to these displays. Sidelights and front lights are virtually the same as backlights. The difference is just the position of the light. Front lights sit on the side or slightly in front of the TFT layers. They are designed so that the light they produce shines through the TFT panel and bounces off the reflective polarizing agent back through the display.

A transmissive TFT uses a backlight. Most TFT LCD panels today are designed with a backlight. The source of the light is mounted at the rear side of the LCD panel and shines light towards your eyes through the TFT panel"s polarizing medium (liquid crystal). Small displays, such as cell phones or calculators, use light source that is placed along the sides of the display.

The common TFT-display backlight is the CCFL (cold-cathode fluorescent lamp). CCFLs are similar to fluorescent light tubes that you commonly find in offices and homes. Their advantage is that they are small, inexpensive, replaceable, and cheap.

The polarizing medium in a TFT that transmits or blocks the backlight is clear, so any light shining on the display from the front competes with the backlight. If the light source shining on the front of the TFT display is strong enough, such as sun on a sunny day, it simply overpowers your laptop TFT display"s backlight and the display image is washed out. A reflective TFT display is usually a better choice for applications with high ambient light.

LED technology has only recently achieved the white light necessary to illuminate these panels. LEDs are the choice these days because they are stable over temperature ranges, durable, and very energy efficient. That is why if you buy a laptop with a TFT LED back-lighted display, it is possible that it will go for as much as 8 hours with your battery.

Displaying a custom image or graphic on a LCD display is a very useful task as displays are now a premium way of providing feedback to users on any project. With this functionality, we can build projects that display our own logo, or display images that help users better understand a particular task the project is performing, providing an all-round improved User Experience (UX) for your Arduino or ESP8266 based project. Today’s tutorial will focus on how you can display graphics on most Arduino compatible displays.

The procedure described in this tutorial works with all color displays supported by Adafruit’s GFX library and also works for displays supported by the TFTLCD library from Adafruit with little modification. Some of the displays on which this procedure works include:

While these are the displays we have, and on which this tutorial was tested, we are confident it will work perfectly fine with most of the other Arduino compatible displays.

For each of the displays mentioned above, we have covered in past how to program and connect them to Arduino. You should check those tutorials, as they will give you the necessary background knowledge on how each of these displays works.

For this tutorial, we will use the 2.8″ ILI9325 TFT Display which offers a resolution of 320 x 340 pixels and we will display a bitmap image of a car.

As usual, each of the components listed above can be bought from the links attached to them. While having all of the displays listed above may be useful, you can use just one of them for this tutorial.

To demonstrate how things work, we will use the 2.8″ TFT Display. The 2.8″ TFT display comes as a shield which plugs directly into the Arduino UNO as shown in the image below.

Not all Arduino displays are available as shields, so when working with any of them, connect the display as you would when displaying text (we recommend following the detailed tutorial for the display type you use of the above list). This means no special connection is required to display graphics.

Before an image is displayed on any of the Arduino screens, it needs to be converted to a C compatible hex file and that can only happen when the image is in bitmap form. Thus, our first task is to create a bitmap version of the graphics to be displayed or convert the existing image to a bitmap file. There are several tools that can be used for creation/conversion of bitmap images including, Corel Draw and Paint.net, but for this tutorial, we will use the Paint.net.

The resolution of the graphics created should be smaller than the resolution of your display to ensure the graphics fit properly on the display. For this example, the resolution of the display is 320 x 340, thus the resolution of the graphics was set to195 x 146 pixels.

Image2Code is an easy-to-use, small Java utility to convert images into a byte array that can be used as a bitmap on displays that are compatible with the Adafruit-GFX or Adafruit TFTLCD (with little modification) library.

With this done, we are now ready to write the code. Do note that this procedure is the same for all kind of displays and all kind of graphics. Convert the graphics to a bitmap file and use the Img2code utility to convert it into a hex file which can then be used in your Arduino code.

To reduce the amount of code, and stress involved in displaying the graphics, we will use two wonderful libraries; The GFX library and the TFTLCD library from Adafruit.

The GFX library, among several other useful functions, has a function called drawBitmap(), which enables the display of a monochrome bitmap image on the display. This function allows the upload of monochrome only (single color) graphics, but this can be overcome by changing the color of the bitmap using some code.

The Adafruit libraries do not support all of the displays but there are several modifications of the libraries on the internet for more displays. If you are unable to find a modified version of the library suitable for your the display, all you need do is copy the code of the drawBitmap() function from the GFX library and paste it in the Arduino sketch for your project such that it becomes a user-defined function.

The first two are thex and y coordinates of a point on the screen where we want the image to be displayed. The next argument is the array in which the bitmap is loaded in our code, in this case, it will be the name of the car and the text array located in the graphics.c file. The next two arguments are the width and height of the bitmap in pixels, in other words, the resolution of the image. The last argument is the color of the bitmap, we can use any color we like. The bitmap data must be located in program memory since Arduino has a limited amount of RAM memory available.

As usual, we start writing the sketch by including the libraries required. For this procedure, we will use the TFTLCD library alone, since we are assuming you are using a display that is not supported by the GFX library.

Next, we specify the name of the graphics to be displayed; car and title. At this stage, you should have added the bit array for these two bitmaps in the graphics.c file and the file should be placed in the same folder as the Arduino sketch.

With that done, we proceed to the void loop function, under the loop function, we call the drawbitmap() function to display the car and the text bitmap using different colors.

The last section of the code is the drawBitmap function itself, as earlier mentioned, to use the drawbitmap() function with the Adafruit TFTLCD library, we need to copy the function’s code and paste into the Arduino sketch.

Plug in your screen as shown above. If you are using any other display, connect it as shown in the corresponding linked tutorial. With the schematics in place, connect the Arduino board to your PC and upload the code. Don’t forget the graphics file needs to be in the same folder as the Arduino sketch.

That’s it for this tutorial guys. The procedure is the same for all kinds of Arduino compatible displays. If you get stuck while trying to replicate this using any other display, feel free to reach out to me via the comment sections below.
