Embodiment Construction

[0061] The invention provides a backlight assembly combination of a liquid crystal display system. Figure 2A is an exploded view of assembled components in an LCD system according to an embodiment of the present invention. Figure 2B is along Figure 2A The cross-sectional view taken in the direction of 2B-2B. The LCD system 100 includes an LCD panel 110 mounted on a backlight system 200 via an assembly frame 210 .

[0062] The liquid crystal display panel 110 may be a multilayer structure, including a liquid crystal layer sandwiched between two transparent substrates. The liquid crystal display panel includes a plurality of pixel electrodes, and the pixel electrodes are driven by a switching device to adjust the light passing through the liquid crystal.

[0063] exist Figure 2A Here, one or more lighting components 260 are mounted on the frame 210 and connected to the protruding contact pads 212a. The light guide plate 220 is installed on the frame 210 between the ligh...

Abstract

A backlight assembly includes a frame for mounting a liquid crystal display panel, a light guide plate and one or more light-emitting components. The frame includes a plurality of conductive components embedded within the frame body and extending into the contact pads to connect the light emitting components. The conductive element is externally connected to a power supply for supplying current to the light-emitting element.

Description

technical field [0001] The invention relates to a backlight assembly of a liquid crystal display (LCD), in particular to a frame structure of the backlight assembly. Background technique [0002] In transmissive and transflective LCDs, the backlight is usually used to illuminate from the back of the LCD panel (on the other side from the viewer). Figure 1A It is an exploded view of each combined component in the known technology LCD system. Figure 1B is along Figure 1A The cross-sectional view taken in the direction of 1B-1B. The structure of the LCD system usually includes a frame 63 , in which a liquid crystal panel 10 , prism layers 22 , 24 , a light scattering layer 26 , a light guide plate 61 and a reflective plate 65 are stacked. The liquid crystal panel 10 is usually connected with a flexible printed circuit board 12 for driving operation. [0003] The frame 63 is generally rectangular, corresponding to the general outline of the liquid crystal panel 10 . A light...
