wsvga tft lcd white screen in stock

The game will compile and work, I can see it working on the serial monitor.  The issue is the screen stay white.  I can load examples codes and the display screen works perfectly.

If you want to buy a new monitor, you might wonder what kind of display technologies I should choose. In today’s market, there are two main types of computer monitors: TFT LCD monitors & IPS monitors.

The word TFT means Thin Film Transistor. It is the technology that is used in LCD displays.  We have additional resources if you would like to learn more about what is a TFT Display. This type of LCDs is also categorically referred to as an active-matrix LCD.

These LCDs can hold back some pixels while using other pixels so the LCD screen will be using a very minimum amount of energy to function (to modify the liquid crystal molecules between two electrodes). TFT LCDs have capacitors and transistors. These two elements play a key part in ensuring that the TFT display monitor functions by using a very small amount of energy while still generating vibrant, consistent images.

Industry nomenclature: TFT LCD panels or TFT screens can also be referred to as TN (Twisted Nematic) Type TFT displays or TN panels, or TN screen technology.

IPS (in-plane-switching) technology is like an improvement on the traditional TFT LCD display module in the sense that it has the same basic structure, but has more enhanced features and more widespread usability.

These LCD screens offer vibrant color, high contrast, and clear images at wide viewing angles. At a premium price. This technology is often used in high definition screens such as in gaming or entertainment.

Both TFT display and IPS display are active-matrix displays, neither can’t emit light on their own like OLED displays and have to be used with a back-light of white bright light to generate the picture. Newer panels utilize LED backlight (light-emitting diodes) to generate their light hence utilizing less power and requiring less depth by design. Neither TFT display nor IPS display can produce color, there is a layer of RGB (red, green, blue) color filter in each LCD pixels to produce the color consumers see. If you use a magnifier to inspect your monitor, you will see RGB color in each pixel. With an on/off switch and different level of brightness RGB, we can get many colors.

Wider viewing angles are not always welcome or needed. Image you work on the airplane. The person sitting next to you always looking at your screen, it can be very uncomfortable. There are more expensive technologies to narrow the viewing angle on purpose to protect the privacy.

Winner. IPS TFT screens have around 0.3 milliseconds response time while TN TFT screens responds around 10 milliseconds which makes the latter unsuitable for gaming

Winner. the images that IPS displays create are much more pristine and original than that of the TFT screen. IPS displays do this by making the pixels function in a parallel way. Because of such placing, the pixels can reflect light in a better way, and because of that, you get a better image within the display.

As the display screen made with IPS technology is mostly wide-set, it ensures that the aspect ratio of the screen would be wider. This ensures better visibility and a more realistic viewing experience with a stable effect.

Winner. While the TFT LCD has around 15% more power consumption vs IPS LCD, IPS has a lower transmittance which forces IPS displays to consume more power via backlights. TFT LCD helps battery life.

Normally, high-end products, such as Apple Mac computer monitors and Samsung mobile phones, generally use IPS panels. Some high-end TV and mobile phones even use AMOLED (Active Matrix Organic Light Emitting Diodes) displays. This cutting edge technology provides even better color reproduction, clear image quality, better color gamut, less power consumption when compared to LCD technology.

What you need to choose is AMOLED for your TV and mobile phones instead of PMOLED. If you have budget leftover, you can also add touch screen functionality as most of the touch nowadays uses PCAP (Projective Capacitive) touch panel.

This kind of touch technology was first introduced by Steve Jobs in the first-generation iPhone. Of course, a TFT LCD display can always meet the basic needs at the most efficient price. An IPS display can make your monitor standing out.

I plugged the LCD straight into the Mega and kept on having problems, so I kept fiddling with the library and sketch until I got something to happen, which was the display being off-centered and not full-screen.

I am using the UTFT library ( circa 2012, as the newer version doesn"t work, even when using the exact same settings and whatnot ) from Rinky Dink Electronics.

What I did to the sketch was run it with different controllers until something displayed, which is the ILI9327, and then I changed that entry in the library ( the .cpp file ) to match what I thought were the X and Y limits of the LCD, 479 and 319, respectively:

AU Optronics Corp. (hereafter called AUO) B133HTN01.0 (Product Code: AUO102D) is a 13.3 inch diagonal a-Si TFT-LCD display panel product, with an integral WLED backlight system, With LED Driver , without touch screen. It features an operating temperature range of 0 ~ 50°C , a storage temperature range of -20 ~ 60°C . It"s general features are summarized by Panelook in the following: Glare Surface, Landscape type, White LED Backlight, Wide Aspect Ratio, Signal Interface Position Reverse , eDP 1.2..

I tried the 8-Bit wiring next. (I don"t know if I that was supposed to work, after I set the SPI mode jumpers)... Anyway, I tried it, but I only get a blank screen and in the serial monitor there"s always this line in the message:

You don"t appear to be communicating with the screen. I wonder if you have a configuration error in your sketch? Can you post the sketch you"re using?

I seem to have a similar problem. (Newbe alert!) I have a new Raspberry Pi B+, V 1.2, and a 2.8" Capacitive Touch Screen Panel. Have worked with the supplied NOOBS 8GB card and found much of the GPIO workable using the HDMI connection. I have closed the solder bridge for the GPIO #18 dimming. However, I have been unable to get an image or text on the Touch Screen Panel. It does, however, light up. I have used the "easy_start" instructions (for the Capacitive Touch Screen) and have tried to modify my existing OS kernel with the "detailed instructions." At one point I was able to dim and brighten the screen. However, I"m now in the position of having the boot hang. This now happens with whatever card I try to set the system up with. The last instruction being "i2c-core: driver [ft6x06_ts] using legacy resume method". I"ve re-soldered the headers without a change in behavior. Any suggestions about how to proceed?

I am having similar problem with a 2.8" TFT LCD with Cap Touch Breakout Board w/MicroSD Socket (https://www.adafruit.com/product/2090). Tried reflowing the pins and different jumper wires/breadboard locations. Also tried soldering the three locations on the back to see if SPI mode works. Same white screen with SPI. Finally after some searching online, I found this post. The following picture was taken after re-opening the three locations, to show the 8-bit mode wiring that I did. I am using the stock graphicstest example sketch. Serial monitor always shows unknown LCD driver chip: 0. Does this mean mine is also a bad copy?

I have a new 2.8" capacitive touch screen, Adafruit part#2423. I have a freshly-downloaded debian-wheezy installed on an SD card. I connected the display, but just white screen. When I attempt to follow the instructions at https://learn.adafruit.com/adafruit-2-8 ... sy-install, and run "curl -SLs https://apt.adafruit.com/add | sudo bash

sudo apt-get install -y adafruit-pitft-helper" (in a shell on a separate HDMI monitor) I get this response "/usr/bin/sudo: /usr/bin/sudo: cannot execute binary file". I have read http://forums.adafruit.com/viewtopic.ph ... ve+TFT+LCD but I don"t see this listed. I am very new to this, though I have been using Unix (and programming in C) off and on since 1978.

No changes made, powered up on the third day, and nothing but a white screen on the ILI9341? So i say, must have blew the t4 some how. Hot air removed the t4, on goes the new one and again a few runs later and i get a white screen again? Checked all my pin assignments, voltages and they are all good.

I picked up the project again today and de-soldered my SAMD51 T4 clone pcb as I need speed! The T4 would have been perfect, so tried a few code changes, got the screen running in the setup function (static text etc), but as soon as it enters the loop(), you guessed it....white screen. Its as if the t4 is too fast on spi or something, but I have changed the clock speeds down to 5mhz and yield the same results...
