Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (5" diagonal) bright (12 white-LED backlight) and colorfu 480x272 pixels with individual pixel control. As a bonus, this display has a optional resistive touch panel attached on screen by default.

The shield is fully assembled, tested and ready to go. No wiring, no soldering! Simply plug it in and load up our library - you"ll have it running in under 10 minutes! Works best with any classic Arduino (UNO/Due/Mega 2560).

This display shield has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller. You can connect more sensors, buttons and LEDs.

Of course, we wouldn"t just leave you with a datasheet and a "good luck!" - we"ve written a full open source graphics library at the bottom of this page that can draw pixels, lines, rectangles, circles and text. We also have a touch screen library that detects x,y and z (pressure) and example code to demonstrate all of it. The code is written for Arduino but can be easily ported to your favorite microcontroller!

For 5 inch screen,the high current is needed.But the current of arduino uno or arduino mega board is low, an external 5V power supply is needed. Refer to the image shows the external power supply position on shield ER-AS-RA8875.

If you"ve had a lot of Arduino DUEs go through your hands (or if you are just unlucky), chances are you’ve come across at least one that does not start-up properly.The symptom is simple: you power up the Arduino but it doesn’t appear to “boot”. Your code simply doesn"t start running.You might have noticed that resetting the board (by pressing the reset button) causes the board to start-up normally.The fix is simple,here is the solution.

Voltage type: 5v or 3v voltage input voltage，input is selectable. Because TFT can only work under 3.3 V voltage, so when the input voltage VIN is 5V, need through the 3.3 V voltage regulator IC step down to 3.3V , when the input voltage of 3.3 V, you need to use the zero resistance make J2 short , is equivalent to not through the voltage regulator IC for module and power supply directly.

This 2.0”LCD display adopts T7789V driver chip and has 320*240 color pixels (RGB565). It uses IPS TFT display and can display 18-bit color(16-bit is basically used). The module performs excellently in displaying color bitmap. Besides, there is an onboard MicroSD card slot for displaying more pictures. There are two connection ways for this module: pin headers and GDI. Only one fpc cable is needed when working with main-cotnrollers with GDI, which greatly reduces the complexity of wiring.

The module has the advantages of high resolution, wide viewing angle and simple wiring, and can be used in many display applications: waveform monitor display, electronic gift box, electronic weather decorations, etc.

The product is a Breakout module. It adopts SPI communication and has onboard GDI interface, which reduces the complexity of wiring and can easily display the contents read from SD card.

The component TFT supports a 2.8 inch TFT display with a resolution of 240*320 pixels.The display is not soldered on the board, but there is a 14 pin connector for a TFT display. The ILI9341 has been tested.

There are four sample projects for the Arduino IDE which could be downloaded: TFT-Box3D (download here), TFT-Graphic-Test (download here), TFT-HelloWorld (download here) and TFT-HowToUseFonts (download here). And there are two examples for the Arduino IDE for using the touch functionality which could be downloaded: TFT-TouchBtn (download here) and TFT-TouchDraw (download here).

There are two dip switches for the component: SW311 and SW314. If you want to use the TFT display all switches on SW311 have to be on on. If you additonally want to use the touchpad of the display all switch of SW314 have to be on. The following two tables shows the functions and the potential conflicts with other components

In order to use the component you need the Ucglib in Version 1.5.2. This version could be downloaded from GitHub. Additionally you could download from this site..

After the download it"s necessary to add both libraries to your Arduino IDE. Open Sketch > Include Library > Add .ZIP Library ... and select the downloaded archive. Do it for both libraries.

Our new line of 10.1” TFT displays with IPS technology are now available! These 10.1” IPS displays offer three interface options to choose from including RGB, LVDS, and HDMI interface, each with two touchscreen options as capacitive or without a touchscreen.

The new line of 3.5” TFT displays with IPS technology is now available! Three touchscreen options are available: capacitive, resistive, or without a touchscreen.

For TFT-LCD panel manufacturing, gate driver circuit with amorphous silicon thin-film transistor (TFT-ASG circuit) plays an important role. In this paper, we propose two different ASG driver circuit topologies to improve crucial dynamic characteristics and then optimize them with circuit sizing by simulation-based evolutionary method which integrates genetic algorithm and circuit simulator on the unified optimization framework [1]. The first circuit consisting of fourteen a-Si:H TFT devices is…Expand
