A vehicle-mounted liquid crystal display backlight structure with narrow frame and high heat dissipation

Abstract

The invention relates to a vehicle-mounted liquid crystal display backlight structure with a narrow frame and high heat dissipation, comprising a middle rubber frame located on the upper layer, a plurality of diaphragms stacked under the middle rubber frame, a light guide plate stacked under the diaphragm, and a light guide plate stacked on the light guide plate. The lower reflective sheet, the lower frame assembly located under the reflective sheet, is installed on the light bar inside the lower bending edge of the lower frame assembly, and the lower frame assembly is fastened with the middle plastic frame to form the backlight of the vehicle-mounted liquid crystal display. The lower frame assembly includes a lower aluminum frame bent on one long side and a side steel frame surrounded by right-angle bending on three sides. The lower aluminum frame is riveted with the side steel frame by multiple rivets to form a lower frame assembly surrounded by four sides. The side wall thickness of the side steel frame is 0.3±0.03mm. This solution has reasonable design, convenient assembly, narrow frame and high heat dissipation.

Description

Technical field [0001] The present invention relates to the field of display backlight technology, in particular to a narrow bezel high heat dissipation vehicle LCD backlight structure. Background [0002] With the rapid development of the automotive electronics industry, the automotive LCD products continue to develop in the direction of "narrow bezel" and "high heat dissipation"; and the left, right and upper bezels of the automotive LCD backlight limit the "narrow bezel" of the whole machine of the display products. [0003] as Figure 1 As shown, the existing automotive LCD display backlight, mainly by the rubber frame 100, in turn set under the rubber frame 100 three diaphragms 200, light guide plate 300, reflector 400, aluminum frame 500, located in the aluminum frame 500 on the inner side of the bending edge of the light bar (not drawn in the figure) and so on. [0004] In the design of the existing vehicle LCD display industry side-entry backlight, considering the cost, ma...
