What are the reasons and solutions for the white screen when the industrial control LCD screen is turned on?

LCD industrial control LCD screen is now one of the devices that can be seen everywhere. Industrial industries have gradually used industrial control LCD screens, and industrial control LCD screens occasionally have white screens. So, how to solve the white screen failure of industrial control LCD screen? It is a very common phenomenon that the LCD industrial control LCD screen turns on the black screen or blue screen. Black screen and blue screen are problems with the system or hardware, and the white screen failure of the display screen when it turns on is generally a failure of the LCD industrial control LCD screen itself.

Causes of LCD industrial control LCD screen failure:

The white screen failure of LCD industrial control LCD screen may be caused by three aspects: problems with the LCD panel drive circuit, problems with the LCD panel power supply circuit, poor contact of the screen line, and problems with the motherboard control circuit.

If the industrial control LCD screen can be turned on normally, it means that the backlight and high-voltage generation circuit are working properly, indicating that the LCD panel has not received the drive signal; if the screen disappears after shutting down, and then a white screen occurs, it may be a problem with the power board.

This means that no matter whether it is turned on or off, as long as the power is plugged in, the high-voltage generation circuit is in working condition and the backlight source is always lit. That is to say, the high-voltage generating circuit is no longer controlled by the switch, that is, the switching signal sent by the motherboard to the high-voltage generating circuit has lost control. Since the switching signal sent by the motherboard microprocessor is generally controlled by several transistors, the fault may be that the transistor that controls the switching signal is damaged.

LCD industrial control LCD screen fault repair:

1. Remove the shell and check whether the screen line interface is loose or not connected properly.

2. Then turn on the power switch and use a multimeter to measure whether the power supply voltage of the screen line interface is normal. If the power supply voltage is normal, check whether the timing signal and drive signal in the LCD panel drive circuit are normal; if not, then check whether the fuse resistor or fuse inductor near the output end of the screen line is open or damaged. If damaged, replace the damaged components.

3. If the fuse resistor or fuse inductor near the output end of the screen line is normal, then check whether the output voltage of the DC-DC voltage conversion circuit that powers the LCD industrial control LCD screen is normal. If the output voltage is abnormal, check the fuse resistor, PWM controller, switch tube, inductor coil, filter capacitor and other components in this power supply circuit, and then replace the damaged components.

4. If the output voltage of the DC-DC voltage conversion circuit is normal, there are damaged capacitors and other components between the output of the DC-DC voltage conversion circuit and the screen line interface. Check and replace the damaged components. 5. If the power supply voltage of the screen line interface is normal, then check whether the timing signal and drive signal in the LCD panel drive circuit are normal. If not, check the output signal, input signal and power supply voltage of the chip that generates this signal to determine whether the drive chip is damaged. If damaged, replace it.

Desktop portable Stargate 🌌🛸💡

Always liked the episode of SG-1 when Orlin made a mini Stargate using various parts ordered online and from Major Samantha Carter's toaster. This one at least fits in our apartment, all part of the round LCD work we are doing with the ESP32-S3.

Advantages of the application of industrial touch screens on machine tools

1. Improve production efficiency: The intuitive operation and powerful data processing capabilities of the industrial touch screen make the operation of machine tools easier and faster. Operators can quickly understand the status of the equipment, adjust production parameters, and reduce production delays and downtime caused by improper operation. At the same time, the display can also realize real-time monitoring of the production process to ensure the smooth completion of production tasks, thereby improving production efficiency.

2. Improve product quality: Through the precise control and real-time monitoring functions of the industrial touch screen, machine tools can be accurately processed according to the preset processing parameters, reducing processing errors and scrap rates. At the same time, the display can also display various data in the processing process in real time, helping operators to adjust production parameters in time to ensure the stability and consistency of product quality.

3. Reduce maintenance costs: The industrial touch screen has fault diagnosis and alarm functions. Once an abnormal situation is detected, the corresponding warning information will be displayed immediately to help operators take timely measures to avoid accidents. This preventive maintenance function greatly reduces equipment failure rate and maintenance costs. In addition, the display screen also has data recording and reading functions, which can record abnormal operation data of machine tools for post-analysis and report generation, providing strong support for equipment maintenance and maintenance.

4. Promote intelligent development: With the continuous advancement of industrial automation and intelligence, the application of industrial control touch screens in machine tools will be more extensive and in-depth.

MJPEGs are a great way to play small animations on TFTs 🎞️ 🖥️ 🔄

With our ESP32-S3 TFT experimenter board, we're now able to use the Arduino_GFX https://github.com/moononournation/Arduino_GFX library by moononournation which has native RGB TFT support and excellent example code. This example is playing MJPEG files, a simple animation format https://en.wikipedia.org/wiki/Motion_JPEG with just JPEGs glued together. We wired up a MicroSD card over SPI for quick file storage and retrieval, or 1-bit MMC works, too. files are converted with ffmpeg: 'ffmpeg -i "wash.mp4" -vf "fps=10,vflip,hflip,scale=-1:480:flags=lanczos,crop=480:480" -pix_fmt yuvj420p -q:v 9 wash.mjpeg', natch! And then they play, about 9fps is the rate we're getting for 480x480 pixels.
