Description

M348241 VIII. New Description: 【New Technology Fields】 This is a kind of backlight module and liquid using the same. [Previous technology] @LCD display has been widely used in various information, communication and consumer products. in. However, since the liquid crystal itself does not have a light-emitting property in the liquid crystal display panel, in order to achieve the display effect, the liquid crystal display panel needs to provide a light source device, such as a backlight module, and the function thereof is to provide a surface light source with sufficient brightness and uniform distribution to the liquid crystal display panel. . Please refer to FIG. 1 for a perspective exploded view of a prior art backlight module. The backlight module 100 includes a metal back frame 110, a reflective sheet 12A, a plastic frame 13A, a light guide plate 14A, and a plurality of light sources 150. The metal back frame 110 has a bottom plate 111 and two side edges 112 extending vertically upward from opposite edges of the bottom plate 1U. The two side edges 112 respectively include a plurality of rectangular card slots 113. The plastic frame 130 is a hollow rectangular frame, and includes a plurality of end-to-end side walls 131. The outer side surface of the plurality of side walls 131 is provided with a plurality of protrusions 132 corresponding to the card slots 113 of the metal back frame 110. The light guide plate 140 includes a light incident surface 14ι, a light exit surface 142 perpendicularly connected to the light incident surface 141, and a bottom surface 143 opposite to the light exit surface 142. When the backlight module 1 is assembled, the metal back frame 11 and the plastic frame 13 are correspondingly engaged by the plurality of slots 113 and the plurality of protrusions 132 to form a receiving space (not shown). The light guide plate 140 is received in the receiving space, and the reflective sheet 12 is disposed adjacent to the bottom surface 143 of the light guide plate. The plurality of light sources 150 are disposed adjacent to the light incident surface 141 of the light guide plate 14, and the emitted light is incident on the light guide plate. The light guide plate 140 is then emitted through the light exit surface 142 of the light guide plate 14 . However, in the actual assembly, since the plastic frame 130 and the metal back frame 11 are both separate components, the protruding block 132 and the card slot 113 are combined and fixed in a snap-fit manner, which is prone to assembly errors.
