Field of the Invention The present invention relates to a side-in-light type backlight module, and more particularly to a side-in-light type backlight module having a light-emitting diode. [Prior Art] Side-lit backlight modules are often used in notebook computers. In the past, the edge-lit backlight module mostly used a cold cathode ray tube (CCFL) as its light source. Recently, however, light-emitting diodes (LEDs) have gradually replaced the trend of cold cathode ray tubes. The light-emitting diodes currently used in the side-lighting type backlight module are mainly white light-emitting diodes. The white light emitting diode has a higher luminous efficiency than the cold cathode ray tube, but its color saturation is inferior to that of a cold cathode ray tube. Generally, a white light emitting diode system is formed by a blue LED chip with a yellow phosphor to cause a white light effect, or a red, green, and blue LED chip to be mixed into white light. Among the two, white light mixed with red, green and blue LED chips has better color saturation. However, when the temperature rises, the red, green, and blue LED chips will produce a change in party attenuation, wavelength shift, and driving voltage, which results in a shift in turbidity and chromaticity. Therefore, red, green, and blue LED chips must be equipped with a color control management system (CMS) to maintain brightness and chromaticity stability. The color control management system includes a light sensor, a control board and a voltage. The light sensor is used to sense the amount of light emitted by the red, green, and blue LED chips. The control board controls the voltage source according to the amount of light measured by the light sensor, and performs feedback control on the input voltages of the red, green and blue LED chips in 200916902 to obtain better white light. Therefore, how to stably read the correct 7C degree and chromaticity value through the light sensor is the most important thing. The assembly position and structure of the light sensor is a key factor affecting the reading of correct brightness and chromaticity values. FIG. 1 shows the structure of a conventional side-lighting type backlight module using a light-emitting diode. The backlight module 100 includes a white light emitting diode 1 2, a light guide plate 104, a reflective sheet 106 and a plastic frame 108, the relative positions of which are shown in FIG. The liquid crystal panel 110 has a visible area W. After the white light emitting diode 1 〇 2 emits light, the light entering the light guide plate 104 may form total reflection in the light guide plate 104 or be reflected by the reflection sheet 106 into the visible region w of the liquid crystal panel no. The light sensor 120 is adjacent to the side of the bottom of the light guide plate 1〇4. As shown in the figure, a gap 1〇9 is formed between the side of the reflecting sheet 1〇6 and the bezel 1〇8. The light sensor 12 is placed in the gap 109 to sense the brightness and chromaticity of the light leaking from the end of the light guide plate 104, and generate a corresponding signal, and then transmit the signal to the flexible circuit board 13 (). In the control panel (not shown). The liquid crystal display is becoming thinner, but the size of the existing light sensor is about (about 5 mm, so if it is applied to a thin light guide plate, the optimal light sensitivity will not be obtained. In addition, the light guide plate will follow the humidity, The temperature changes to the thickness or bend, so that the sensing distance D changes accordingly, so the brightness and chromaticity values sensed by the light sensor will be unstable', resulting in a wrong adjustment of the color control management system. Gradually narrowing the edge, if the position of the light sensor is improperly placed, for example, the light sensor 120 is placed in the visible area W, which will affect the visible area W area, then the black shadow generated by the light sensor 12 may appear on the picture. In addition, the object of the present invention is to provide a side-in-light-type f-light module or a liquid crystal display group to which the side-input type is applied, which is appropriately set. Light sensing, and maintaining a stable sensing reference, thereby correctly sensing the brightness and color value, and improving the quality of the kneading surface. Also / other objects of the present invention and the technical problems of the gamma of the present invention To further One embodiment of the present invention is a side-in-light type backlight module, including a plastic frame with a number of edge strips, and a side strip for describing some or all of the objectives or other purposes. Wherein - having a cavity; - the light guide plate is located in the plastic frame - and has a - first light entrance end and a light exit end face, the first light entrance end = should be in the side of the side strip - the light exit end Corresponding to the other of the side strips, wherein a part of the light-emitting end surface is located inside the cavity; a second light-emitting diode is disposed on the side of the light guide plate and faces the first-peripheral end surface; In the cavity, the light is emitted from the first light-emitting diode and exits the light-emitting end face. In the embodiment of the present invention, the cavity has a first opening and a second opening; The eccentric device is disposed in the second opening of the cavity.

The preferred embodiment is as follows: The cavity has a flange at the top, and two have a photosensitive gap at the bottom and are located in the cavity. The portion of the light-emitting end surface of the body is located between the flange and the photosensitive notch. The bottom surface of the plastic frame is recessed along the periphery of the photosensitive notch for placing the flexible circuit board to which the light sensor is connected. The reflecting surface is configured to reflect the light emitted from the light-emitting end surface to the domain device. The light-emitting end surface and the first light-incident end surface may be disposed on opposite sides of the light guide plate. The diode body and the first light-emitting diode are respectively disposed on the light guide plate. The light guide plate has a second human light end face facing the second light-emitting diode. The light-emitting end face is adjacent to the first and second persons. Light end face. The light sensor is located at the center of the light exit end face and is approximately equal to the first and second light incident end faces. [Embodiment] The foregoing and other technical contents, features, and effects of the present invention will be apparently described below in conjunction with a parametric phase. The directional terms mentioned in the following embodiments, for example, up, down, left, right, front or back, etc., are merely directions in which the reference is added. Therefore, the terminology used is used to describe that it is not intended to limit the invention. * Figure 2A shows a side cross-sectional view of a liquid crystal display module. The liquid crystal display module 200 is composed of a liquid crystal panel 210 and a light-emitting backlight module 22 on one side. The liquid crystal panel 210 is mounted on the backlight module 22A, and the two are assembled by a plastic frame 230. Referring to FIG. 2B and FIG. 2 simultaneously, the structures of the two ends 202 and 204 of the backlight module 220 are respectively displayed. The backlight module 22 has a 200916902 light guide plate 224, a light emitting diode 222 disposed on one side of the light guide plate 224, and a reflective sheet 226 disposed under the light guide plate 224. The light guide plate 224 is not limited to a wedge shape or a flat shape. 2A is an example of a wedge-shaped light guide plate 224 which is gradually thinned from left to right. The left end is a thicker light incident end surface 224a, and the right end is a thin light exit end surface 224b. 2B is an enlarged cross-sectional view showing the light incident end surface 224a of the light guide plate 224 and the light emitting diode 222. The light-emitting diode 222 is disposed on a lamp holder 222a. The lamp holder 222a is fixed on a bottom plate 250. The combination of the bottom plate 250 and the plastic frame 230 is as shown in FIG. 2B. The light of the light-emitting diode 222 faces the light-incident end surface 224a, and the direction is indicated by an arrow. The light incident end surface 224a faces the light emitting surface of the light emitting diode 222. to allow light to enter the light guide plate 224. Most of the light entering the light guide plate 224 is reflected by the total reflection or by the reflection sheet 226, is emitted from the upper surface of the light guide plate 224, and enters the liquid crystal panel 210. However, a small amount of light is leaked from the light-emitting end surface 224b of the light guide plate 224, and the brightness and chromaticity of the light source can be known by sensing the leaked light. 2C shows a plastic frame 230 having a cavity 232 for embedding the light-emitting end surface 224b of the light guide plate 224 and a light sensor 240 therein. Since the cavity 232 has the function of fixing the light-emitting end surface 224b and the light sensor 240, the light sensor 240 and the light-emitting end surface 224b can be maintained at a certain photosensitive distance, thereby maintaining the sensed brightness and chromaticity values stable. The inner wall of the cavity 232 includes a reflective surface 234' that contacts the interior of the cavity 234 toward the light exit end surface 224b. When the light leaks out of the light-emitting end surface 224b, it is reflected by the reflecting surface 234 to the light-sensing 240, and the light path is indicated by an arrow. The light sensor 24 is directly fixed to a flexible circuit board 242. When the light sensor 240 senses luminosity, chromaticity or energy, a signal is generated and the signal is transmitted through a flexible circuit board 242 to a control board (not shown in 200916902). The control board performs feedback control on the input voltages of the red, blue and green LED chips according to the measured signals to obtain better white light. " Figure 3A shows the position of the cavity 232 in an embodiment of the invention, and also the preferred assembly position of the light sensor 240. The frame 23 has two opposite side strips 230a, 230b. The cavity 232 is disposed at a central position of the side strip 23〇a. When the plastic frame 230 and the light guide plate 224 are used, the light-incident end surface 2 of the light guide plate corresponds to the edge strip fiber 'and the light end surface island rides on the opposite side strip 230a and is fixed in the cavity 232 . Since the - side of the light guide plate 224 facing away from the light source is the position where the light leakage amount is the largest and the light mixing effect is optimal, the light sensor 240 is placed in the cavity 232 to have an optimum photosensitive effect. One. FIG. 3B is an enlarged view of the cavity 232 of FIG. 3A. The top of the cavity 232 has a flange 236' which forms a photosensitive notch 238 at the bottom. The flange 236 can fix the light guide plate 224' such that the light exit end surface 224b is located between the convex edge, the edge 236 and the photosensitive notch, and the distance between the light guide plate 224 and the light sensor 240 is determined. As such, the light sensor 240 does not affect the amount of light received by the displacement of the light guide plate 224, resulting in a change in brightness and chromaticity of the backlight module 220. A side strip 23〇a is provided for the liquid crystal panel 210 to be placed thereon. 4A shows the assembled relationship of the bottom of cavity 232 to light sensor 240. The bottom surface of the side strip 230a has a recess 239 disposed along the periphery of the photosensitive notch 238. When the light sensor 240 is buried into the photosensitive notch 238 from the bottom to the top, the recessed portion 239 can accommodate the flexible circuit board 242 to avoid increasing the overall thickness of the backlight module 22A. 4B is a cross-sectional view of FIG. 4A showing the internal structure of the cavity 232. In addition to the photosensitive notch 238, the cavity 232 defines an opening 237 between the flange 200916902 236 and an extension 235 of the frame 230 for the light exit end surface 224b of the light guide plate 224 to extend into the cavity 232. The reflective surface 234 can be a bevel or a curved surface ' toward the opening 237 and the photosensitive notch 238. 4C is a top view of FIG. 4B showing the assembled relationship of the light guide plate 224 and the reflective sheet 226 with the cavity 232. 4D shows that the brightness enhancement film 410 is placed over the light guide plate 224. The diffusion sheet 42 is placed on the surface of the brightness enhancing film 41 and the flange 236 and a portion of the diffusion sheet 420 is more likely to be caught in the groove 231 of the side strip 230a.
