Description of the new type: [Technical field to which the new type belongs] A creation is about a combined light guide plate with a light mixing area, which is a light guide plate with a light mixing area and can be combined, also- A large-area light guide plate formed by combining the above light guide plates. [Previous technology] Moonlight switch unit provides a uniform light source system, which is generally used for display devices. Spring settings: especially non-luminous display devices, such as LCD panels, which can be used in mobile communications' digital cameras, displays and televisions. Generally speaking, display devices have the function of self-luminous to provide sufficient brightness and appropriate colors. However, the LCD panel itself does not have the function of self-luminous, so it is necessary to provide sufficient and uniform brightness by the backlight module. And color, in which the backlight module is divided into two types: direct type and edge type according to the position of the light source. 1. The first picture of Mai Zhao, this figure shows the cross-section view of the traditional edge-lit backlight module. The top-to-bottom structure is an outer layer plate (乂), a cymbal plate, a diffuser plate (C), and a reflective plate (D), and a light source (E) is provided on the side of the light guide plate. The light passes through the light guide plate. The light source is transmitted to the diffuser plate (c) through the dots and the reflective plate under the light guide plate, and is diffused and emitted by the diffuser plate (c), and passes through the cymbal (β) to provide a liquid crystal panel in front of the backlight module. Needed light source. This type of edge-light backlight module is often used in small and medium-sized displays. However, due to the small number of light sources and the large light emitting surface, the average brightness is relatively small. According to the second figure, it is a structure diagram of a general direct type backlight module. It consists of a diffuser plate (G), a light source (η), a reflector (丨), and an outer frame (J). Light source part M281195 = ⑹ is transmitted towards diffuser ⑹, partly via reverse expansion: plate ⑹. The direct type backlight module has a lot of light sources, and the reason t, makes the * average brightness larger, but the average hook degree is poor. In addition to the light sources of the two backlight modules mentioned above, in addition to cold cathode tubes, other optoelectronic components can also be replaced. For example, using a luminous body! The light source of the light module is even a light source with different spectral ranges. The light source is to increase the color display range and make the colors more vivid. The situation occurs. However, to avoid the uneven color of the display 6Α 丄The light source that is at the front and has a light emitting surface must mix light sources of different spectral ranges uniformly. In Jixia 4 North and Qianwei, the direct-type moonlight modules use different sources of different spectrum ranges, and it is often difficult to achieve the conditions of uniform color. On the other hand, the frequency spectrum of a light source is often subject to significant spectral changes by the light source itself or the surrounding elements, that is, the color difference. The unexpected direct-type backlight module happened. To extend the distance between the two light sources for 4 makes the problems of uniformity and color uniformity of the backlight module more serious. It is necessary to provide a backlight module that can provide a light source with uniform brightness and color at the same time, and reduce the difference in color changes caused by the increase in brightness.
