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.

Classification of LCD screens

TN LCD screen:

TN type is the most mainstream mode adopted by LCD monitors at present, and is widely used in entry-level and mid-range panels. The common viewing angle is not outstanding in performance indicators and has a natural chronic disease. The TN panels seen on the market are all improved TN+film, where film is a compensation film, which is used to make up for the lack of viewing angle of TN panels. In general, TN panels are products with obvious advantages and disadvantages. They are cheap and have a response time that can meet the requirements of games. In the classification of LCD screens, TN has an unsatisfactory viewing angle and unrealistic color performance, which are obvious disadvantages.

STN LCD screen:

The display principle of STN type is similar to TN. The difference is that the liquid crystal molecules of TN twisted nematic field effect rotate the incident light by 90 degrees, while the STN super twisted nematic field effect rotates the incident light by 180 to 270 degrees.

DSTN LCD screen:

DSTN scans the twisted nematic LCD screen through a double scanning method to achieve the display purpose. DSTN is developed from super twisted nematic display (STN). Since DSTN uses double scanning technology, the display effect is greatly improved compared with STN in the LCD display classification.

IPS LCD display:

IPS is also called wide viewing angle. It is a panel technology launched by Hitachi in 2001. It is also commonly known as "Super TFT". From a technical point of view, the liquid crystal molecules of traditional LCD displays generally switch between vertical and parallel states. MVA and PVA improve it to a vertical-bidirectional tilt switching mode. The biggest difference between IPS technology and the above technologies is that no matter what state the liquid crystal molecules are always parallel to the screen, but the rotation direction of the molecules is different in the power-on/normal state-note that the rotation of MVA and PVA liquid crystal molecules belongs to spatial rotation (Z axis), while the rotation of IPS liquid crystal molecules belongs to rotation in the plane (X-Y axis). IPS also has the disadvantage of slow response time. 16.7M colors, 178-degree viewing angle and 16ms response time represent the highest level of IPS liquid crystal displays.

What should I do if the screen has bright spots or dark spots?

If the industrial control LCD screen has bright spots (pixels that are always on) or dark spots (pixels that are not luminous), you can try the following methods to solve the problem:

1. Check the screen status

Confirm the problem: First, confirm whether the bright spots or dark spots on the screen are persistent. You can observe the problem more clearly by displaying a solid color background (such as all black or all white).

Check the ambient light: Make sure there is no strong light source directly shining around the screen, because strong light may cause visual misjudgment.

2. Try software repair

Pixel repair tool: Some software tools (such as JScreenFix, Dead Pixel Tester, etc.) can help fix bright spots or dark spots. These tools try to "wake up" or "repair" the faulty pixels by quickly flashing the pixels on the screen.

How to use: Download and install the pixel repair tool and follow the software instructions. It is usually necessary to display a specific pattern or color on the screen and let the software run for a period of time (such as 10-30 minutes).

3. Physical repair method

Light pressure method: For bright spots, you can try to gently press the bright spot position with a soft object (such as an eraser) while quickly switching the screen display content. The principle of this method is to change the arrangement of liquid crystal molecules through physical pressure, which may help repair bright spots.

Temperature method: For dark spots, you can try to gently wipe the screen surface with a slightly damp lint-free cloth, and then let the screen run at normal temperature for a while. The principle of this method is to activate the faulty pixel points through slight temperature changes and humidity changes.

4. Hardware inspection

Check the connection cable: Make sure that the power cord and data cable of the screen are firmly connected and not loose or damaged. Loose connections may cause unstable signals, resulting in bright spots or dark spots.

Check the interface: Check whether the interface of the screen (such as HDMI, VGA, LVDS, etc.) has dust or foreign matter, and use a soft brush to gently clean it if necessary.

Traditional mechanical dashboards are gradually being replaced by LCD screens. These screens can display key information of the vehicle, such as speed, speed, fuel level, tire pressure, etc., with high resolution and high contrast. Through the graphical interface, drivers can obtain this data more intuitively and reduce visual fatigue. In addition, the smart dashboard can also display different information layouts according to driving modes (such as economic mode, sports mode) to provide a personalized driving experience.

2. Center console display

The LCD screen on the center console is the core of the car's infotainment system. It is not only used for navigation and multimedia playback, but also can control the vehicle's air conditioning, seat heating, windows and other functions. Touch screen operation makes the control of these functions more intuitive and convenient. For example, the driver can adjust the air conditioning temperature through virtual buttons or sliders on the screen, or navigate through voice commands. Some high-end models also support wireless connections, such as Apple CarPlay and Android Auto, further improving the intelligence level of the car system.

3. Rearview mirror display

The LCD screen in the rearview mirror can provide a wider field of view and clearer images. For example, the streaming rearview mirror captures the real-time picture behind the vehicle through the camera and displays it on the screen, reducing the blind spot of the traditional rearview mirror. This technology is particularly useful when reversing and changing lanes, improving driving safety.
