What s going on with the streaked flickering of the phone screen

If the screen of the mobile phone flashes, the screen is broken.

Cover glass: the outermost layer of the mobile phone screen plays a protective role, its upstream glass substrate industry investment threshold and production technology door requirements are high, the market is mainly monopolized by the United States Corning, Japan Asahi Glass, Electric Glass and Germany Schott and other companies, domestic manufacturers are mainly based on substrate processing and manufacturing.

Touch module: a key link to improve the human-computer interaction experience of mobile phones, at present, TDDI (TouchWith Display Driver Integration) integrated with touch IC and panel driver IC is the mainstream solution, and with the increasing maturity of product manufacturing process, the yield rate continues to improve, and the profitability of the industry is strong.

According to the material of the screen, the mainstream screens of smartphones can be divided into two categories, one is LCD (abbreviation of Liquid Crystal Display), that is, liquid crystal displays, such as TFT and SLCD screens.

The other is OLED (Organic Light-Emitting Diode), that is, organic light-emitting diodes, such as AMOLED series screens. The most fundamental difference between LCD and OLED is that OLED is self-illuminating, while LCD needs to be illuminated by a backlight plate to display.

According to the display technology driving mode of the screen, it can be divided into two categories: passive matrix and active matrix. The difference between passive matrices and active matrices is the way the current is driven.

When the external current passes, the arrangement of the liquid crystal will change, and after the current stops, if the liquid crystal arrangement remains in place (with memory), it is called the active matrix; Once the current disappears, it returns to its original position and must be charged again to be arranged, which is called a passive matrix.

If the screen color is abnormal, such as a blurred screen, a green screen, or an improper screen color, we recommend that you do the following:

1.Turn off your phone and restart it.

2.If the phone can be used normally, please check whether you use the theme software, and it is recommended to restore the theme that comes with the phone.

4.If the above operation is invalid, or the operation cannot be continued after the screen of the mobile phone is blurred, please bring the purchase receipt, repair card and machine to the local OPPO customer service center for testing.

If this problem occurs on Samsung mobile phones, it is generally recommended to troubleshoot and deal with the following steps:

1.Shut down the machine and restart.

2.If it is invalid, please bring the purchase invoice, repair card and machine to the Samsung service center for a detailed inspection by an engineer.

Samsung Service Center Address Information Customer Service**, you can inquire through the following methods: please log in to Samsung's official website - click on the upper right corner of after-sales service - click to find Samsung Service Center - select the product you want to inquire about and the province and city where you are located to search.

What to do if your phone screen flickeres.

The touch screen of the mobile phone is normal, and it will flash streaks every second, is it necessary to repair the mobile phone?

There are several reasons why the phone screen keeps flashing streaks:

1. The problem of cable arrangement (the connection line between the screen and the motherboard of the mobile phone), the screen is not easy to break without physical damage, which is caused by the loose or damaged cable of the mobile phone, 2. A certain screen corner is crushed. Now the white screen should be a broken wire or virtual welding.

3. Streaks appear due to screen damage or other hardware failures.

Solution: 1. In fact, many times it is caused by static electricity, and we can use the following methods to remove static electricity. Use the electrostatic electrostatic in the lighter to shock the screen (cover the malfunction with a paper towel stained with water to shock) and change the electric field, not all of which are applicable, so everyone should use them with caution.

2. Or use transparent glue to paste and tear on the screen until the screen restores touch, and pay attention to holding the phone when using this method to prevent the phone from falling.

3. There may be a problem with the system settings, if your phone system is Android or above, then you can try to open the settings, click on the developer options to cancel the check of "display screen update".

4. You can also turn off the auto-brightness adjustment option in the settings.

5. There is no way to eliminate the above faults, so it is best to take it to the maintenance point for maintenance.

The reasons for the vertical streaks that appear on the phone screen flickering are as follows:

1. The inner screen is damaged: the common mobile phone screen is generally two percent, when the mobile phone accidentally breaks the screen, if it can still be used normally, it is because only the outer screen of the mobile phone is broken, and the screen display and mobile phone functions will not be affected. If the inner screen is damaged, there will be display problems such as vertical stripes of the screen, yellow spots, flickering, or even not being able to display.

If these problems occur on the phone, it is highly likely that the internal screen of the phone is caused by the phone.

2. Motherboard problems: The chips on the motherboard of some mobile phones are soldered loosely or the wiring will also cause faults such as vertical stripes when there is a problem.

If you are using a Huawei phone and find that the screen suddenly flashes while using the phone, you can troubleshoot the problem based on the following conditions:

1.If your phone's screen suddenly appears to be splashing.

It may be due to the interference of human static electricity on the display signal when the environment is dry, the mobile phone system has an automatic error correction function, and the display will return to normal within a few seconds, if it does not return to normal, please try to restart the mobile phone and recover.

2.If your phone doesn't appear until you're using an app.

If the above methods do not solve your problem, we recommend that you back up your data in advance (WeChat QQ and other apps must be backed up separately) and bring the relevant purchase voucher to a nearby Huawei customer service center for maintenance.

It may be that the screen is not sensitive, or some screens are damaged or you use it improperly, which will cause this, and this needs to be repaired.

The first possibility is the screen brightness problem, open [Settings], after entering the page, you will see various function options, manually slide down to find [Display and Brightness], and turn off the button next to [Auto]; The second possibility is that the system is stuck, press and hold the shutdown button and the volume button for three seconds at the same time, find the upper [slide to shut down] in the pop-up interface, slide to the right to shut down and then restart; The third possibility is that the mobile phone screen is damaged, and it needs to be sent to the repair shop for testing and repair.
