tft lcd white screen 2.4 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.

Capacitive Touch Panel, WHITE LED backlight, All Viewing Angles, Wide temperature range, Transmissive polarizer, 450 NITS, CTP controller: FT6236, RoHS Compliant

The Capacitive touch panel is activated with anything containing an inductive load such as a finger or stylus. It allows for multi-touch options. When using the capacitive touch screen, the display needs a separate controller to interface with the touch panel. The display for capacitive touch is brighter since the touch panel is transparent.

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! 240x320 pixels with individual RGB pixel control, this has way more resolution than a black and white 128x64 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" diagonalTFTs

Orient Display sunlight readable TFT displays can be categorized into high brightness TFT displays, high contrast IPS displays, transflective TFT displays, Blanview TFT displays etc.

The brightness of our standard high brightness TFT displays can be from 700 to 1000 nits. With proper adding brightness enhancement film (BEF) and double brightness enhancement film (DBEF) and adjustment of the LED chips, Orient Display high brightness TFT products can achieve 1,500 to 2,000 nits or even higher luminance. Orient Display have special thermal management design to reduce the heat release and largely extend LED life time and reduce energy consumption.

Our high contrast and wide viewing angle IPS displays can achieve contrast ratio higher than 1000:1 which can make readability under strong sunlight with lower backlight luminance. High brightness IPS displays have been widely accepted by our customers with its superb display quality and it has become one of the best sellers in all our display category.Transflective display is an old monochrome display technology but it has been utilized in our color TFT line for sunlight readable application. Orient Display has 2.4” and 3.5” to choose from.

Blanview TFT displays are the new technology developed by Ortustech in Japan. It can provide around 40% of energy consumption for TFT panels which can use smaller rechargeable or disposable batteries and generate less heat. The price is also lower than traditional transflective TFT displays. Orient Display is partnering with the technology inventor to provide 4.3” and 5.0”.

Touch panels have been a much better human machine interface which become widely popular. Orient Display has been investing heavy for capacitive touch screen sensor manufacturing capacity. Now, Orient Display factory is No.1 in the world for automotive capacitive touch screen which took around 18% market share in the world automotive market.

Considering the different shapes of the touch surface requirements, Orient Display can produce different shapes of 2D touch panel (rectangle, round, octagon etc.), or 2.5D touch screen (round edge and flat surface) or 3D (totally curved surface) touch panel.

Of course, Orient Display can also offer traditional RTP (Resistive Touch Panel) of 4-wire, 5-wire, 8-wire through our partners, which Orient Display can do integration to resistive touch screen displays.

High Level Interfaces: Orient Display has technologies to make more advanced interfaces which are more convenient to non-display engineers, such as RS232, RS485, USB, VGA, HDMI etc. more information can be found in our serious products.

i"m working on this about 4 days straight but nothing happened.. I was being really gentle with lcd so no damage nor i over voltage it. So it"s probably because of the code but i can"t find where the problem is :/ Can you guys help me out with this thing?

The 2.4 Inch TFT LCD Touch Screen LCD Display Module for Arduino is a beautiful large touchscreen display shield with built in microSD card connection. The LCD has excellent vivid color contrast. This TFT display is big (2.4″ diagonal) bright (4 white-LED backlight) and colorful (18-bit 262,000 different shades). It has 240×320 pixels with individual pixel control which is way more resolution than a black and white 128×64 display. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.
