Abstract

The invention relates to the technical field of liquid crystal display. The invention provides a narrow-frame TFT light leakage prevention structure. The structure comprises a TFT display screen module and a backlight source module attached to the lower portion of the TFT display screen module, the TFT display screen module is further connected with an FPC flexible circuit board, the backlight source module comprises a metal frame, and the metal frame forms a metal retaining wall on the peripheral edge of the TFT display screen module. A plastic frame at the periphery of the TFT display screenmodule is cancelled; a metal retaining wall is used for surrounding the periphery of the TFT display screen module; according to the narrow-frame TFT light leakage prevention structure, the visual frameless effect is achieved, the situation of frame light leakage of a TFT display screen module is avoided, the absorbance of the metal retaining wall is extremely small, the brightness loss of a visual area can be ignored, and the highlight effect of a product is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, and more specifically relates to a light-leakage preventing structure of a narrow frame TFT. Background technique [0002] "Ultra-narrow bezel" means that in the mobile phone screen of a smartphone, the proportion of the visible area is higher, the visual effect is better, and it can attract the attention of consumers. In the prior art, the fixed frame of the liquid crystal display is made of plastic material, which has light transmittance. When the backlight is emitting light, the light will pass through the surroundings of the liquid crystal display, causing light leakage from the frame of the display module, which seriously Affected the effect of the LCD screen. One way to solve the problem of light leakage in the frame of the display module is to increase the distance between the visible area and the edge of the display screen as much as possible, and cover the non-vis...
