tft lcd white screen2.4 manufacturer
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).
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 TFT LCD module has an 8/9/16/18-bit Parallel Interface with brightness clocking in at 850, contrast ratio at 500:1, and luminance at 450 candelas per square meter.
Microtips Tenchology, LLC believes that small displays like the Transmissive Normal White 2.4” TFT LCD module become more important as handheld devices, along with wearable devices, continue to grow in popularity among users. As such, the quality of the displays become crucial for whatever task the device is being used for.
In addition to manufacturing and supplying small LCD modules, the company also performs customizations, offering both resistive and capacitive touch. O-Film and MR-Film modules are also a part of its capabilities.
Microtips Technology, is one of the world’s leading manufacturers and suppliers of LCDs (Liquid Crystalline Displays). The company utilizes the latest in trends and technologies to produce a complete range of LCD types. Moreover, the company offers turnkey solutions like product development and design for customers in OEM manufacturing and design.
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.
In this Arduino touch screen tutorial we will learn how to use TFT LCD Touch Screen with Arduino. You can watch the following video or read the written tutorial below.
As an example I am using a 3.2” TFT Touch Screen in a combination with a TFT LCD Arduino Mega Shield. We need a shield because the TFT Touch screen works at 3.3V and the Arduino Mega outputs are 5 V. For the first example I have the HC-SR04 ultrasonic sensor, then for the second example an RGB LED with three resistors and a push button for the game example. Also I had to make a custom made pin header like this, by soldering pin headers and bend on of them so I could insert them in between the Arduino Board and the TFT Shield.
Here’s the circuit schematic. We will use the GND pin, the digital pins from 8 to 13, as well as the pin number 14. As the 5V pins are already used by the TFT Screen I will use the pin number 13 as VCC, by setting it right away high in the setup section of code.
I will use the UTFT and URTouch libraries made by Henning Karlsen. Here I would like to say thanks to him for the incredible work he has done. The libraries enable really easy use of the TFT Screens, and they work with many different TFT screens sizes, shields and controllers. You can download these libraries from his website, RinkyDinkElectronics.com and also find a lot of demo examples and detailed documentation of how to use them.
After we include the libraries we need to create UTFT and URTouch objects. The parameters of these objects depends on the model of the TFT Screen and Shield and these details can be also found in the documentation of the libraries.
So now I will explain how we can make the home screen of the program. With the setBackColor() function we need to set the background color of the text, black one in our case. Then we need to set the color to white, set the big font and using the print() function, we will print the string “Arduino TFT Tutorial” at the center of the screen and 10 pixels down the Y – Axis of the screen. Next we will set the color to red and draw the red line below the text. After that we need to set the color back to white, and print the two other strings, “by HowToMechatronics.com” using the small font and “Select Example” using the big font.
Next is the distance sensor button. First we need to set the color and then using the fillRoundRect() function we will draw the rounded rectangle. Then we will set the color back to white and using the drawRoundRect() function we will draw another rounded rectangle on top of the previous one, but this one will be without a fill so the overall appearance of the button looks like it has a frame. On top of the button we will print the text using the big font and the same background color as the fill of the button. The same procedure goes for the two other buttons.
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.
The main component of Me TFT LCD Screen module is a LCD display communicating with Makeblock Orion through serial port to show characters and graphics of different size and colors. The module is integrated with MCU and memory chip, and the Chinese characters, letters, and figures stored in the memory chip can be invoked easily through the serial port. Its blue/gray ID means that it has a double-digital signal port and needs to be connected to the port with blue or gray ID on Makeblock Orion.
Since the port of Me TFT LCD Screen has blue/gray ID, you need to connect the port with blue or gray ID on Makeblock Orion when using RJ25 port. Taking Makeblock Orion as example, you can connect to ports No. 5 as follows:
If you use Arduino to write a program, the library Makeblock-Library-master should be invoked to control the Me TFT LCD Screen. This program serves to display different graphics and characters through Arduino programming.
This module (Me TFT LCD Screen – 2.2 Inch) contains a voltage converter, an STM32 chip, and a serial flash memory of 2M. In contrast with other displays, it needs only serial port for communication, so it is easy to operate and connect.
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.
