Description of the Invention: [Technical Field] The present invention relates to a display and a light source module thereof, and more particularly to a liquid crystal display and a side-into-light backlight module thereof group. [Prior Art] _Technology advances 'M's technology evolved from early Cathode Ray Tube (CRT) to flat panel displays (shirts (4) (4), FPD), such as Liquid Crystal DisPlay (LCD) . Flat-panel displays are becoming the mainstream of the current display market due to their compact size and high brightness and contrasting image quality. ^In the current flat panel display, liquid crystal displays are most commonly used in many home appliances and electronic products, such as LCD TVs, computer monitors, notebook computers (N〇teb〇〇k), mobile phones, and personal digital assistants. (Personal Digital Assistant, PDA), etc. Since the liquid crystal display panel in the liquid crystal display cannot emit light, it is necessary to rely on the backlight module to provide the light source. The backlight module of the uranium, such as the direct-input light-emitting backlight module and the side-in-light backlight module, mostly uses a cold cathode fluorescent lamp (CCFL) as a light source. Although the cold cathode fluorescent lamp has a strong light-emitting brightness, which is sufficient for the liquid crystal display to produce a high-brightness picture, the cold cathode fluorescent lamp tube is easily broken, requires high voltage driving, has long lighting time, contains mercury components, and The emitted light contains shortcomings such as ultraviolet light (Ultraviolet, UV). 5 200842456 ~ "299twf.doc/n. In view of the above shortcomings, some backlight modules use Light Emitting Diodes (LEDs) as light sources. Light-emitting diodes are not easily broken, low-voltage driving, lighting speed Fast, mercury-free, and the light that is emitted is almost free of ultraviolet light, and the brightness of the current two-pole light is indistinguishable from that of the cold cathode fluorescent tube. Therefore, the light-emitting diode is also suitable as a backlight module. The light source of the backlight module is mostly white. The side-lit backlight module with the light-emitting diode as the light source has many types, except for the white light-emitting diode. In addition to the light source, there are also side-lighting backlight modules using light-emitting diodes of red, green, and illuminating light as the light source. The side-lighting backlight module using the three primary color light-emitting diodes can be used by A mixture of three primary colors of red, green, and blue produces white light. Figure 1 depicts a top view of a conventional side-lit backlight module, and Figure 2 depicts a front view of the light source of Figure 1 in the x-direction. Please also refer to the map 1 and FIG. 2, the backlight module 1A includes a light guide plate 1 L (Light Guide piate, LGP) and a light source 120. The light source 12A includes a circuit board 122 and a plurality of different colors of the light emitting diode 124a. 124b, 124c, wherein the light-emitting diodes 124a, 124b, and 124c are red, green, and blue light-emitting diodes, respectively, and the three are packaged in different packages. The plurality of light-emitting diodes 124a, 124b And 124c are disposed on the circuit board 122, and are regularly arranged in a row along the Y direction. The light emitted by the light emitting diode has high directivity, that is, the light emitting diodes 124a, 124b, 124c emit Monochromatic Light will move in a single direction and gradually spread out. Therefore, when the light source 120 emits light, the portion of the light guide plate 11 adjacent to the light source 120 may be monochromatic. The light is not completely diffused, and the monochromatic light is mixed unevenly, and then a color spot appears on the light-emitting surface 112. The area where the color spot appears is called the light-mixing area m, and the light-mixing area U]L is in the x-direction. The length of the upper part is called the mixed light distance D. Theoretically, after the monochromatic lights emitted by the LEDs 124a, 124 and 124c pass through the light-mixing region U1, the monochromatic lights are evenly mixed into white light, so that the light-emitting surface 112 is outside the light-mixing region U1. The portion of the portion where the color unevenness or the color shift does not occur. However, the monochromatic light emitted from the light-emitting diodes 124a and 124C adjacent to the edge of the circuit board 122 passes through the light-mixing area, since it is not adjacent to the other The color light is sufficiently mixed, so that the color deviation of the light-emitting surface 112 outside the light-mixing region m is still present, and the occurrence of the color-shifting region affects the color uniformity of the backlight module i, thereby destroying The quality of the LCD screen. 3 is a front view of a conventional side-lit backlight module in the X direction of the light source of FIG. 4 and FIG. 4, the light source 22G of the backlight module includes a circuit j counter 222 and a plurality of light emitting diodes 26b, 226C disposed on the circuit board 222.

Different from the foregoing back, and moving, in a single package 224, the arrangement of the light emitting diodes, the two electrodes, and the first one are concentrated, and the light mixing region m of the light guide plate 110 is m ..., And there is still a color shift region M2 at the edge of the light guide plate 110. 7 200842456 95276 21299twf.doc/n How to improve the color shift problem to raise the liquid crystal display crying The current important issue.
