With the continuous development of technology, the use of e-book readers is becoming more and more popular. In terms of display screens of e-book readers, the performance of OLED displays has attracted more and more attention, because OLED displays are ultra-thin, ultra-light, High contrast, high brightness and many other performance advantages, and it can effectively reduce power consumption and extend battery life, so more and more e-book readers begin to use OLED displays.

However, opinions are divided on whether OLED displays are prone to screen burn-in after prolonged use. Below, we will conduct some analysis and discussion on this issue.

First of all, it needs to be clear that when an OLED display screen displays images, it emits light through light-emitting diodes. If these light-emitting diodes cannot consume current evenly after a long period of use, "afterimages" will be formed on the display screen, which is what we usually call screen burn-in. More prone to screen burn-in.

Secondly, we need to understand that OLED display is different from traditional LCD display. It is an organic material, a semiconductor material similar to organic fluorescence, which displays images by self-luminescence. The organic materials used in OLED displays may gradually decompose or oxidize when exposed to strong light or frequently changing colors, resulting in uneven brightness of the OLED display and loss of brightness and color accuracy. In this case, the display is prone to screen burn-in.

Moreover, since the pixels of the OLED display are prone to burn-in after a long period of use, once the burn-in problem occurs, it is basically irreparable. Because once the burn-in problem on the OLED display is formed, it is impossible for us to solve the problem by changing the pixels, so various fields where the OLED display is widely used need to take some precautionary measures to avoid burn-in of the OLED display Phenomenon.

A feasible way to solve the burn-in problem of the OLED display screen after long-term use is to add some pixel erasing procedures to the OLED display screen. A pixel wiper is a software program that causes an OLED display to change in a specific pattern that evenly consumes the OLED display's light-emitting diodes to avoid pixel burn-in. Similarly, when the OLED display is not in use for a long time, it is also necessary to pay attention to the protection of the screen to avoid the problem of screen burnout caused by the inability of the OLED display to be used. When using an OLED display, you should avoid using high-brightness images, avoid images entering the screen for a long time and cause high-brightness pixels to be burned, and try to avoid OLED displays displaying static content for a long time.

To sum up, although the OLED display has many advantages, it is prone to burn-in problems after long-term use, and once the burn-in occurs, it is difficult to repair. Therefore, in the process of using OLED displays, we need to take some preventive measures to avoid burn-in of OLED displays. When choosing a suitable OLED display, we should also consider more reliable brand manufacturers to ensure OLED displays. the quality of.
