According to relevant reports, there is an aunt who spent 10,000 4 to buy olED TV, changed three times in three years, changed three new ones, and recently broke down, returned with more than 10,000 yuan.
According to relevant personnel, OLED is suitable for small screens, such as Apple 12, Apple 13 and other mobile phones.
At present, the technology of OLED is not perfect.
For the burn-in screen problem, OLED mobile phones and TVs are difficult to avoid.
OLED pixel life will appear with time brightness attenuation, when a certain area of the screen for a long time to display a fixed screen, the pixel brightness attenuation speed of this area will be faster than other places, resulting in unrecoverable dark spots on the screen, which is what we often call OLED burn-screen phenomenon.
Mobile phones are slightly better because they switch between different screens and turn off the screen for a long time.
OlED TV burn-screen situation, after all, OLED TV is expensive, the use time is long, and the possibility of fixed screen screen is greater.
Reduce playback of images with fixed frames
Images with fixed screens appear in the same position as the long-term picture. It only takes a few hundred hours, and there will be a burning screen in that area. Therefore, when we use OLED TVs or monitors, we should try to make each picture area of the screen show active rather than fixed images, so as to avoid burning the screen.
The simplest way is to watch TV for a long time, do not watch programs with the same icon for a long time, including but not limited to ordinary live TV signals, domestic streaming media platforms, etc., because these contents have the same characteristics, that is, there will always be station logos in the same position, such as CCTV will definitely have CCTV logos, Tencent, iQiyi and other streaming media will also have their own logos.
Of course, this is not to let everyone not watch, but to avoid watching programs with fixed logos for a long time, change channels when there is nothing to do, and watch other programs. In a word, do not let any area of the screen display the same picture for a long time, which is the best solution to prevent burning the screen.
Pixel shifting and pixel refresh
Pixel shifting is a mandatory technique, also known as pixel displacement.
Pixel refresh usually requires the user to do it manually, generally speaking, there are three modes, simple pixel refresh is actually to make the pixel transfer brought about by the picture inconsistencies return to normal. The second mode is to refresh the entire screen pixel. The third mode is to deeply refresh the pixels of the entire screen, which also takes longer, usually more than 1 hour.
Pick a product that supports local brightness adjustment
Because this function is not supported by every OLED TV, that is, the local brightness adjustment function. It is the icon brightness adjustment function, when the TV detects that the inactive area of the screen is an icon, text or a fixed picture, then the brightness of this area will be reduced to avoid image residue.
But the problem is that this function is not the standard function of the current OLED products, there are some old OLED TVs that support this function, when watching the film, you can reduce the brightness of icons and subtitles. Some products that use the latest LG OLED panels may not support this feature. For example, the Philips 806 OLED TV supports this function, and skyworth G90 does not support this function.
