For LED/LED displays, non-uniform heating is the main cause of colour aberration and blurred images, and these poor image quality can be seen everywhere on the display and even at the corners of the display. For OLED displays, the non-uniform heat generated at the top edge can cause uneven aging of the display, resulting in noticeable chromatic aberration. High-performance graphite sheets can prevent these problems from occurring in monitors and achieve high-quality picture effects.
