Why are there vertical lines on the phone screen?

First, use the screenshot function of your smartphone to take a screenshot of the current interface, then look at the screenshot image, slide left and right or zoom in and out to confirm whether the vertical lines work together with the screen. The vertical line indicates that when working with the screen, the cause is a software failure. Please restart the phone or restore the factory settings. If the vertical lines are unable to track the movement of the frame, it may be due to a hardware issue.

How to repair vertical lines on mobile phone screen?

1.LCD screen: If the LCD screen of the mobile phone is damaged and the LCD screen is damaged by pressing, the LCD screen will leak, and straight lines perpendicular to the screen or horizontal lines will appear. If the leakage is severe, a watermark effect will appear.

2.Display cable: The display cable is a connecting cable between the mobile phone’s internal screen LCD and the motherboard chipset. The display cable is virtually welded together. If the contact is not good, there will be straight lines on the phone screen, and the phone screen will turn black after the display cable is cut off.

3.Display chip assembly: Even if the display chip assembly on the motherboard fails, straight lines will not appear on the mobile phone screen. The mobile phone screen will be black. Therefore, if there are straight lines on the mobile phone screen, it is not a problem with the motherboard display chip assembly.

4.Neither the picture nor the wiring can be judged from the appearance, so you must disassemble the phone and first press and hold the wiring to reinstall the wiring. If the straight line disappears on the screen, it means there is a wiring problem, otherwise it can be determined to be a problem with the LCD panel.

Tips for maintaining your mobile phone screen

1.Anti-static

Although today's touch screens are very strong, static electricity will definitely have a violent effect. Static electricity can damage the screen under certain circumstances. Therefore, it is necessary to prevent static electricity from causing damage to the screen of mobile phones in daily life.

2.Oil and sweat

Oil dirt and water are electrically conductive media, which will definitely cause damage to the screen. In addition, oil dirt and sweat must be acidic. The acidity will definitely have a corrosive effect and will also cause damage to the screen.

3.High temperatures

Under strong sunlight, the temperature of the mobile phone screen becomes higher, the screen becomes taller, and the screen will drift. In addition, the screen is also a high-tech electronic technology product. There are some data transmission substances, which can easily degrade under high temperatures, causing the screen to become insensitive or lose its function.

4.Magnetic field

If you put a magnet on the screen, you will soon find that the capacitive screen has a temporary failure. Over time, a permanent failure will occur. Therefore, try to prevent close contact between mobile phones and other magnetic objects.

5.Charging voltage

The principle of the capacitive screen is that after a finger touches the electrostatic capacitive screen, the point current on the screen will disappear. The screen will deliver current equally from the four corners to compensate for the direction of the finger pressing, thus causing drift when the voltage is unstable. Therefore, try to avoid charging after the battery is lower than 20%. If it is lower than 20%, it is best to charge immediately.
