Please refer to m]p (10) and the straight-line image, which is a kind of side-surface light source. If it is composed of light source 1, lead x 'main, capture board 4, reflection film 2 and frame 6 Dreaming, the thickness of the substrate of the 'light board 4' is about 〇·4 mm~1〇. In the surface light source device of Fig. 1, the light source is disposed on the side of the light guide plate, and the light source is transmitted from the side end surface and the y rear ridge by the king reflection in the light guide plate 4, and then the diffusion point is used to diffuse the light ray at various angles and is emitted from the front surface of the light guide plate. % into a uniform surface source. The surface light source device of Fig. 1 has the characteristics of light weight, thin shape, narrow frame and low consumption, and is suitable for small and medium size backlight modules, such as notebook computers. However, with the advent of large-size LCD TVs, the main considerations must be sufficient brightness, wide viewing angle, sharp image contrast, and standard service life. In order to meet the above requirements, the direct-surface light source device has become the mainstream technology for large LCD TVs. Referring to Fig. 2, it is a direct-surface light source device, which is mainly assembled by components such as a light source 1, a diffusing plate 5, a reflective film 2, and a frame 6. The surface light source device of Fig. 2 has a light source disposed directly below the diffusion plate, and the light source is reflected by the reflection film 2, and is uniformly distributed upward by the diffusion plate 5 by 1 〇 doc doc doc M295743 = to be: front side. In order to improve the uniformity of the light, the diffusing plate must have a light thickness of about 2 _' so that the first rate of the diffusing plate is only about 60%, so that the light utilization rate is too low. In order to improve the surface, the brightness of the source needs to increase the size of the lamp according to the panel size. Therefore, the installation space increases the weight, thickness, power consumption, and poor uniformity of the module to be improved.
