The invention discloses a light guide plate display device capable of reducing light leakage from a light source, which includes a mounting frame and a light guide plate. The cross-section is isosceles trapezoidal, the horizontal bar is provided with an assembly groove, a backing plate is installed on the side of the assembly groove away from the light guide plate, and a circuit board is installed in the middle of the side of the backing plate close to the light guide plate, In addition, a light source is installed on the circuit board, and fixing strips are installed on the upper and lower sides of the circuit board. This kind of light guide plate display device that can reduce the light leakage of the light source is connected to the light guide plate through the set fixing strips, and makes it connected to the light guide plate The gap between them is transferred to the inner side of the fixing bar to reduce the penetration of light, and then through the cooperation of the inner side of the horizontal bar and the anti-slip pad, the installation stability of the components in the assembly groove is improved, and the assembled installation frame is not easy to loose , thereby reducing the light leakage of the light source.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a light guide plate display device capable of reducing light leakage from a light source. Background technique [0002] As electronic products are developing toward light, thin, short, and small goals, the concept of thinning has become the direction of continuous efforts for display devices. Due to the trend of thinning, the thickness of display devices is correspondingly limited, and thinning of display devices is related to One of the key factors is the thickness of the backlight module. According to the different positions of the light source, the backlight module can be divided into two types: direct type and side light type. Compared with the direct type backlight module, the side light type backlight module Thinner thickness can be achieved, and the edge-lit backlight module with a thinner light guide plate can further reduce the overall thickness of the backlight module ...
