What does Tou mean?
Through-the-picture means that after the screen displays a still image for a long time, it will leave a residual image. Moreover, this ghost is permanent and cannot be eliminated. Generally speaking, it means "burning screen". It usually appears on plasma TVs and mobile phones equipped with organic light-emitting diode screens. For mobile phones with OLED screens, with the current technology, all OLED screens will be affected to some extent. The reason is that organic light-emitting diodes (OLEDs), that is, organic light-emitting diodes, have self-luminous characteristics, and the life of these organic materials that cause them to emit light is limited. When the organic light-emitting diode screen displays a static picture for a long time, these organic materials will accelerate the aging speed, reduce the brightness and leave an afterimage on the screen because of their continuous luminescence. By adjusting the screen locking time, turning on the brightness level, changing the dark wallpaper or dynamic wallpaper, and switching the screen display content, the phenomenon of screen penetration can be avoided.
