tft lcd white screen2.4 brands

The other day I finally found a code that worked on my standard 2.8" TFT LCD by Simkeim, but then I pressed the bottom left corner too hard and the screen went white. The code is a calculator code and it worked because the screen showed the numbers and the screen saver, but when I pressed the screen nothing happened. After the screen went white, I "opened" it and saw no damage to the screen. I have tried a bunch of example sketches and now the touch functions work, but nothing is displayed on the screen. The LCD does not have any wires, it just plugs in the board. When I upload a sketch, the backlight changes brightness a bit, and there is a slight line on the left side of the screen, when the code uses dark colors, I can press two parts of the screen and the screen goes dark (except for a small part of the left side).

So, I got a TFT panel that works with the same controller chip that I found on Ali Express and replaced it, and now I can use it without any problems.

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...

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.

Add some jazz & pizazz to your project with a color touchscreen LCD. This TFT display is big (2.8" diagonal) bright (4 white-LED backlight) and colorful! 240x320 pixels with individual RGB pixel control, this has way more resolution than a black and white 128x64 display. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen. We also have a version of this display breakout with a capacitive touchscreen.

If you are using an Arduino-shaped microcontroller, check out our TFT shield version of this same display, with SPI control and a touch screen controller as well

Add some jazz & pizzazz to your project with a color touchscreen LCD. This TFT display is 2.4″ diagonal with a bright (4 white-LED) backlight and it"s colorful! 240×320 pixels with individual RGB pixel control, this has way more resolution than a black and white 128×64 display.

If you need a larger touchscreen, check out the 2.8″ diagonal or 3.5″ diagonal TFT breakouts. For a smaller display, see our non-touch 2.2″ or 1.8″ or 1.44″ diagonal TFTs

Shield for Arduino consists of a TFT LCD display with 2.8 "resistive touch screen, HX8347D graphics controller, resolution 320x240 pixels, 65,000 colors, with white LED backlight, SD card slot and SPI interface. Ideal for building applications that require display data, photos and video, can be interfaced to microcontrollers PIC, Arduino, etc. Note: the package includes only the shield with touch screen display.
