We covered the basics of accelerometer previously inUsing Arduino with Parts and Sensors – Accelerometer Part 1andUsing Arduino with Parts and Sensors – Accelerometer Part 2. Today we’ll be testing KX022-1020 accelerometer using TFT liquid crystal panel. We’ll discuss how to control the TFT LCD in more detail in the next article. In addition, we’ll further exploreArduino Create. For more information about Arduino Create, please refer back tothisarticle.
Let’s briefly review what accelerometer is. An accelerometer is a sensor that can detect the state of motion, such as “tilt,” “shock,” “vibration” and so forth. Accelerometers are classified into one axis, two axes, and three axes. For example, one axis detects one direction (vertical only); two axes detects two directions (vertical and horizontal); and three axes three directions (vertical, horizontal and height).
After adding the library, attach the accelerometer to the Sensor Shield (I2C I/F) and try running the sample program. The accelerometer should be set to 1.8V or 3.0V.
Now the sample program is working fine, let’s try to display the values on a 1.8 inch TFT LCD monitor. Although this TFT liquid crystal monitor has a resolution slightly smaller than 126 x 160 px, it’ll be quite useful when displaying numbers or letters with Arduino etc.
When using the TFT monitor, the connection method and the library used in the program may be different depending on the specification of each TFT monitor. The TFT monitor used in this tutorial is a monitorSainSmart ST7735R. In addition to Arduino, the monitor is also compatible with Raspberry.
In order to use the monitor to run the program in Arduino, we’ll have to modify the downloaded library a little bit.We’ll go over how to control the TFT LCD in more detail in the next article. Once everything is set, you will be able to output numerical values in the monitor as shown in the video below:
In the next part, we’ll create a simple device using the same accelerometer and TFT monitor. We’ll show how to create graphs and display the values obtained from the accelerometer on the TFT monitor.

Focus Displays offers a wide range of standard full color TFT displays. 64 million unique colors, high brightness, sharp contrast, -30C operating temperature, and fast response time are all good descriptions of a TFT display. This is why TFT technology is one of the most popular choices for a new product.
Thin Film Transistor (TFT) display technology can be seen in products such as laptop computers, cell phones, tablets, digital cameras, and many other products that require color. TFT’s are active matrix displays which offers exceptional viewing experiences especially when compared to other passive matrix technologies. The clarity on TFT displays is outstanding; and they possess a longer half-life than some types of OLEDs and range in sizes from less than an inch to over 15 inches.
CCFL’s are still available, but are becoming a legacy (obsolete) component. TFT displays equipped with a CCFL require higher MOQs (Minimum Order Quantities) than displays with LED backlights.
The majority of TFT displays contain a touch panel, or touch screen. The touch panel is a touch-sensitive transparent overlay mounted on the front of the display glass. Allowing for interaction between the user and the LCD display.
Some touch panels require an independent driver IC; which can be included in the TFT display module or placed on the customer’s Printed Circuit Board (PCB). Touch screens make use of coordinate systems to locate where the user touched the screen.
Resistive touch panels are the lowest cost option and are standard equipment on many TFT modules. They are more common on smaller TFT displays, but can still be incorporated on larger modules.
Resistive touch panels are constructed using flexible materials with an air gap between and are coated with a resistive layer. When an object applies pressure to the top layer, it makes contact with microdots located on the bottom layer. This allows the touch screen to find the location of the touch using X and Y coordinates.
Custom resistive touch screens are an option if the customer requires a seal or gasket to be in contact with the glass and not in contact with the touch panel.
Resistive touch panels allow a single touch, although advances in new resistive technology will allow multi-touch operation in the near future. One main advantage of a resistive touch screen is the ability to be activated by the touch of any material. This includes a range of items from a bare finger, to a pencil, to even the edge of a credit card; regardless of its composition.
Capacitive touch panels have become popular with such software as Windows 8®, Android® and Apple®. Additionally it is used in products such as cell phones and tablets, where multi-touch and zoom capabilities are important.
Contrast ratio, or static contrast ratio, is one way to measure the sharpness of the TFT LCD display. This ratio is the difference between the darkest black and the brightest white the display is able to produce. The higher the number on the left, the sharper the image. A typical contrast ratio for TFT may be 300:1. This number ratio means that the white is 300 times brighter than the black.
TFT LCD displays are measured in inches; this is the measurement of the diagonal distance across the glass. Common TFT sizes include: 1.77”, 2.4”, 2.8”, 3”, 4.3”, 5”, 5.7”, 5.8”, 7”, 10.2”, 12.1 and 15”.
TFT resolution is the number of dots or pixels the display contains. It is measured by the number of dots along the horizontal (X axis) and the dots along the vertical (Y axis).
Certain combinations of width and height are standardized and typically given a name and a letter representation that is descriptive of its dimensions. Popular names given to the TFT LCD displays resolution include:
Transmissive displays must have the backlight on at all times to read the display, but are not the best option in direct sunlight unless the backlight is 750 Nits or higher. A majority of TFT displays are Transmissive, but they will require more power to operate with a brighter backlight.
A primary job of the driver is to refresh each pixel. In passive TFT displays, the pixel is refreshed and then allowed to slowly fade (aka decay) until refreshed again. The higher the refresh frequency, the sharper the displays contrast.
The TFT display (minus touch screen/backlight) alone will contain one controller/driver combination. These are built into the display so the design engineer does not need to locate the correct hardware.
If you do not see a Thin Film Transistor (TFT) Display module that meets your specifications, or you need a replacement TFT, we can build a custom TFT displays to meet your requirements. Custom TFTs require a one-time tooling fee and may require higher MOQs.

Different displays use different types of TCONs. In this article we will be talking about TCONs for the IT market: LCD (Liquid Crystal Display) notebook PCs and monitors.
An LCD panel has millions of Red, Green, and Blue (RGB) liquid crystals that are used to block a white backlight when electrical voltage is applied to them. High voltage signals to each individual pixel control how much of the backlight to block. A white display means nothing is being blocked. A black display means all three colors are blocked at maximum effort.
TCONS direct the high voltage driver chips that move the color filters and are usually found on a circuit board that sits below the glass panel (Fig. 1).
eDP connections are fast, use few wires, and are flexible for size, bandwidth and adding features eDP provides all panel connections in one plug, including power, data, and control signals. This is Analogix’s specialty.
While the GPU is responsible for transforming mathematical equations into individual pixels and frames, a TCON takes the individual frames generated by the GPU, corrects for color and brightness, then sends out parts of the image to each individual driver at the panel’s specific timing.
The human eye has an incredible dynamic range. That means we can see both very dark images and very bright images, at the same time. However, neither camera sensors nor display panels can display that range. Your camera generates HDR images by using images from multiple exposures to combine the brightest and darkest parts of the picture. This increases the contrast (dynamic range) between light and dark, pulling out details from darkened or washed out areas.
HDR accurately maps real world color and luminance to a display panel. VESA DisplayHDR™ standard specifies HDR quality, including luminance, color gamut, bit depth, and rise time.
Display panels have difficulty displaying a wide range of brightness. Normal sunlight can reach 10,000 nits, but the backlight on most notebooks today is around 250 nits
VESA DisplayHDR requires the panel to meet minimum brightness, contrast, and color. No panel can reach 10,000nits of natural light. The brightest a 250nit notebook panel can produce is 250nits and any image above 250nits is washed out. Also, no details from 250 nits to 10,000nits can be seen.
The HDR400 specifications require a dimmable backlight which helps with both producing darker blacks and lowering the power consumption. Tone mapping is used to map the whole range of 10,000 nits down to what the panel can handle, so the details can be seen. Tone mapping does not increase the brightness of the panel; it only makes the details visible.
VESA DisplayHDR600 Requires local dimming. No LCD panel can reach the VESA DisplayHDR600 requirement of 6000:1 contrast ratio. However, this can be overcome with local dimming.
For example, a 750:1 contrast panel requires 8 different backlight power settings to reach 6000:1 contrast ratio. However, unless there are thousands of separate regions, local dimming always produces halos around the bright areas. In order to reduce the halos, the following are recommended:
Monitors can use a direct backlight with many regions. An extra layer of liquid crystal can be used to dim the backlight at a specific location but this often results in a panel that is too thick for a notebook.
Notebook backlights use LEDs on the edge of the panel to reduce panel thickness. These can be on 1 side, 2 sides, or all 4 sides. Each edge adds to cost and bezel size.
Global Dimming Power Savings - Figure 6 shows a 15.6” UHD panel with 400nit maximum brightness. Figure 7 shows a comparison of backlight power consumption values between 400nit, 50nit and, respectively 5nit.
The primary goal of color management is to obtain a good match across color devices; for example, the colors of one frame of a video should appear the same on a computer LCD monitor, on a TV screen, and as a printed poster. Color management helps to achieve the same appearance on all of these devices, provided the devices are capable of delivering the needed color intensities. Color management cannot guarantee identical color reproduction, as this is rarely possible, but it can at least give more control over any changes which may occur.
A PC in HDR and SDR modes use different color gamut but the same screen. Dual-panel phones and notebooks need the color of the two sides to match perfectly. Graphic artists for web sites, movies, video games, etc., need to know what they are creating looks the same on their screen as on their customers’ screens.
As panels improve, the color space of new panels may exceed the color space from Windows. This results in displays which look oversaturated. There is a trend towards low blue light or “night shift” panels, while still retaining color accuracy for the other colors. Today, low blue light panels are created by measuring each individual panel, then hoping that the yield is high enough.
Analogix’s Advanced Color Blocking (ACB) technology is used to create consistent image quality across different panels and change color space for different usage modes (Fig. 8). It allows for 3D color gamut rotation in the optical color domain rather than the RGB domain and color space change on the fly, such as color mapping of BT.2020 source to sRGB or DCI-P3 panels. It includes LUT shadow registers and hardware transition calculations (to smooth changes).
Color conversion in the TCON can dynamically and continuously adjust the incoming signal from the GPU for a low blue light color space. This way, no individual panel measurement is needed and yields should increase. While this can also be done by the GPU itself, that takes GPU bandwidth and 500x more power.
Panel Self-Refresh (PSR) – frame buffer in a TCON can maintain a display image without receiving video data from the CPU. For a still image, this allows the GPU to enter a low-power state and the eDP main link to turn off. Allowing the GPU to power down between display updates will save significant power and extend battery life.
Panel Self-Refresh with Selective Update (PSR2) is a superset of the panel self-refresh feature and it allows the transmission of modified areas within a video frame with obvious benefits when watching a movie or playing a game. PSR2 identifies when only a portion of the screen is static, which is a selective update. In PSR2, when the full screen is static, the refresh rate can be lowered for further power savings as done by Intel Low Refresh Rate (LRR). Intel LRR lowers the refresh rate by changing pixel clock or by changing vertical blank depending on the scenario such as idle, playing video, browsing, etc. All Analogix TCONs support Intel LRR.
In-Cell Touch embeds the touch function in the display itself, the panel including all the touch sensors, controllers, and needed processing. This simplifies the production process and reduces weight and reflection by removing the cover glass. It also allows for thinner bezels as there is no need for daughter cards and no separate wires for touch, as well as lighter devices as the cover glass is removed.
Analogix has pioneered the in-cell touch notebook panel TCONs. About 15% of notebooks support touch and we expect the touch attach rate to increase as more active pen support is introduced.
