In this embodiment, the light guide plate 242 is provided with a first through hole 241 connecting the first end surface 242c and the second end surface 242d. Referring to FIG. 4, FIG. 4 is an enlarged schematic diagram of one end of the backlight module 24 in FIG. 3, an implementation In one embodiment, the first through hole 241 is a round hole, and in other embodiments, the first through hole 241 may also be a square hole or a special-shaped hole.

Specifically, the light source 244 faces the first side 242a, and the light source 244 provides light to enter the light guide plate 242 from the first side 242a. With the first end surface 242c as a reference plane, the propagation direction of the light entering the first side 242a is along the first side. 242a points to the direction of the second side 242b. Along this direction, the area where the light can be directly covered (the light is not reflected or refracted) is the second light guide area 246b, and the light is blocked by the inner wall surface 241a of the first through hole 241. The area that cannot be directly covered is the first light guide area 246a. In fact, light can travel to the first light guide area 246a after being reflected or refracted inside the light guide plate 242, but the light is subject to certain loss.

Specifically, after the light emitted by the light source 244 enters the light guide plate 242 from the first side 242a, the brightness of the light in the first light guide area 246a is smaller than the brightness of the light in the second light guide area 246b, increasing the light guide of the first light guide area 246a. The distribution density of the light spots 248 can enhance the brightness of the light emitted from the first light guide area 246a from the first end face 242c, so that the first end face 242c corresponds to the position of the first light guide area 246a and the position of the second light guide area 246b Lights with the same brightness are emitted so that the backlight module 24 provides a surface light source with uniform brightness.

Specifically, from the edge of the first light guide area 246a to the center of the first light guide area 246a, the brightness of the light provided by the light source 244 gradually decreases, and the distribution density of the light guide points 248 can be adjusted corresponding to the gradual increase of the light from the first light guide area 246a. The brightness emitted from the end surface 242c enables the light guide plate 242 to emit light with uniform brightness.

Specifically, the second end surface 242d is inclined to the first end surface 242c, so that the light provided by the light source 244 can be uniformly transmitted to each light guide point 248 on the second end surface 242d, so that after the refraction or reflection of the light guide point 248, the light from the first end surface One end surface 242c shoots out.
请参阅图2，光源244在第一侧面242a的垂直投影覆盖第一侧面242a，以使进入导光板242的光线可以覆盖第二端面242d，光线经过导光点248的作用后，第一端面242c整体均可以发出光线。Please refer to FIG. 2 , the vertical projection of the light source 244 on the first side 242a covers the first side 242a, so that the light entering the light guide plate 242 can cover the second end surface 242d, and after the light passes through the light guide point 248, the first end surface 242c The whole can emit light.
请参阅图3，本实施例中，导光板242的第一端面242c一侧还设有扩散片等光学膜片，以均匀化导光板242射出的光线。导光板242的第二端面242d一侧还设有反射片，以将从第二端面242d漏出的光线经过反射后再次进入导光板 242，提高光线利用率。Please refer to FIG. 3 , in this embodiment, an optical film such as a diffusion sheet is provided on the side of the first end surface 242 c of the light guide plate 242 to uniformize the light emitted from the light guide plate 242 .

The first light guide area 246a has less light, increasing the distribution density of the light guide points 248 in the first light guide area 246a can enhance the light guide effect of the first light guide area 246a, so that the overall brightness of the light emitted from the first end surface 242c is uniform.
