▎ 摘　　要

NOVELTY - The touch display screen has a transparent glass cover that is attached to an upper surface of an INCELL/ONCELL TFT LCD through an optical adhesive layer (OCA). A LED backlight is arranged directly below the INCELL/ONCELL TFT LCD. The end of the INCELL/ONCELL TFT LCD is electrically connected to a flexible printed circuit board (7) through a transparent conductive sheet (5). The end of the LED backlight is provided with a lead end, and the LED backlight is also electrically connected to the FPC circuit board through the lead end. The FPC circuit board is arranged on one side of the LED backlight, and a graphene heat dissipation film is arranged between the LED backlight and the INCELL/ONCELL TFT LCD. The frame of a casing (1) encloses the INCELL/ONCELL TFT LCD and the LED backlight. USE - Mobile phone touch display screen. ADVANTAGE - The overall structure is ingeniously designed, the structure is reasonable and stable, and the flexibility is good. The high-transmission ultra-thin flexible screen glass is used as the transparent glass cover, which greatly reduces the thickness of the touch display screen and realizes the thinness and thinness of the touch display screen. A graphene heat-dissipating film is arranged between the INCELL/ONCEL LTFT LCD and the LED backlight. Effectively ensure that the LED backlight has a good heat dissipation effect, and it does not affect the backlight brightness and brightness uniformity of the LED backlight for the INCELL/ONCELL TFT LCD. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the structure of the mobile phone touch display screen.
