The backlight is generally used to provide the light source required for liquid crystals, such as liquid crystal displays, mobile phone panels, and even popular PDAs, which are all within the scope of backlight applications. The principle is simply that a light guide plate is used to introduce spontaneous light sources, such as lamps (CCFX), light emitting diodes (LEDs), etc., to produce a larger and more uniform light emitting surface; among them, the backlight module A reflecting sheet is provided to reflect the light emitted by the spontaneous light source and then emit it on the front side of the light guide plate. Its advantages are light weight, high brightness, good light angle of view, high light utilization efficiency, and simple structure. Generally, in the process of assembling the backlight module, the spontaneous light source is usually facing the light guide plate. Except for the light emitting surface of the light guide plate, the reflection sheet is pasted, and the reflection sheet provides high reflection efficiency for visible light. And reflections at the bottom and edges of the light guide plate to maintain the luminous efficiency of light emitted from the front of the light guide plate.

The diode light-emitting module 2 a includes a circuit board 20 a and a plurality of light-emitting diodes 2 1 a arranged on the circuit board 20 a. In order to avoid the light-emitting diode 2 a When the light is emitted, it is absorbed by the circuit board 20a. The degree of absorption depends on the material of the circuit board 20a itself and its reflectivity. There is a certain degree of understanding of the light transmitted to the light guide plate 丄 3. Deterioration; Yes, the diode light-emitting module 2 a is being assembled to the light guide plate body! Before a, it will face the light guide plate body before the circuit board 2 〇 a! a is covered with a reflective sheet 2 2 a to reduce the trouble of absorbing light of the circuit board 20 a described above. The step of applying the reflecting sheet 2 a is before the assembling of the diode light-emitting module 2 a to the main body a of the light guide plate; so, regardless of the design and number of the reflecting sheet 3 a, only — The sheet of the reflecting sheet 3 a and the entire structure of the conventional light guide plate is completed, which requires at least two steps of applying the reflecting sheet to the reflecting sheet 2 2 a, — to the reflecting sheet 3 Λ the above two steps are not Actions that can be completed continuously, not to mention when the design and number of the reflective sheet 22a tends to be complicated, its actual assembly and operation is 'a waste of labor and research by Kennett, and' finally proposes a fate, this The creators are aware of the above-mentioned shortcomings. The design is reasonable and effective in improving the above-mentioned short-form creations in accordance with the application of academic theory and considerations of portability. 6 M264520 [New content] The main purpose of this creation is to provide a light guide plate structure, which can be produced in a time-saving manner, and can maintain the luminous efficiency of the light guide plate structure. In order to achieve the above object, the present invention provides a light guide plate structure, which includes a light guide plate body, a light emitting module provided on at least one side edge of the light guide plate body, a body light emitting module, and a light guide plate body and the light guide plate body. A diode is a reflective element between the modules; wherein the diode light-emitting module has a circuit board and a plurality of light-emitting diodes arranged on the circuit board; the reflective element completely covers the guide The bottom surface of the light plate body and the side edge; the reflective element is provided with a plurality of perforations corresponding to the light emitting diode body, the light emitting diode system faces the side edge of the light guide plate body, and is accommodated one by one in the In the perforation, the diode light-emitting module can omit the step of applying the reflection sheet in stages, thereby achieving the purpose of saving time and labor and the light-emitting efficiency of the light guide plate structure. In order for your reviewers to have a better understanding of the characteristics and technical content of this creation, please refer to the following detailed description of this creation and the attached drawings; however, the attached drawings are for reference and explanation only, and are not intended to limit this. creation. [Embodiment] Please refer to FIG. 2A to FIG. 2B. The present invention provides a light guide plate structure including a light guide plate body 1 and two poles provided on at least one side edge of the light guide plate body 1. A light emitting module 2, and a reflective element 3 disposed between the light guide plate body 1 and the diode light emitting module 2; wherein, M264520, the diode light emitting module 2 has a circuit board 2 and is disposed on The plurality of light-emitting diodes 21 on the circuit board 20; the reflective element 3 completely covers the bottom surface and the side edge of the light guide plate body 1; wherein, the reflective element 3 is formed by the bottom surface of the light guide plate body 1. The side edge is integrally formed, or the reflective element 3 is separately covered on the bottom surface of the light guide plate body 1 and the side edge; the reflective element 3 is provided corresponding to the light-emitting diode. The plurality of perforations 31 of 21, the light-emitting diode 2 1 faces the side edge of the light guide plate body 1 and is accommodated in the perforations 3 1 one by one; thereby, the diode light-emitting mode Group 2 may omit the step of pasting the reflective sheet (such as the reflective sheet 2 2 a in the first figure) in stages. Only save the steps, spring can also assemble the moving line smoothly (because there is no need to go back to the original production unit of the pasted reflective sheet, you can go directly to the next step); In addition, the effect of this reflective element · Part 3 is excellent The reflection sheet 3 a and the reflection sheet 2 2 a shown in the first figure are due to the fact that the reflection element 3 of this creation is a hole with the same size as the light emitting diode 21. 3 1 'circuit board 2 0 can still avoid the known space between the reflective sheet 2 2 a and the light guide plate body 1 a to reduce the possibility of light loss; therefore, the light guide plate of this creation The structure system can achieve the purpose of maintaining the luminous efficiency of the light guide plate structure and saving time and labor. The reflective element 3 extends from a side edge of the light guide plate body 1 to a top surface portion of the light guide plate body 1, and in particular, the reflective element 3 faces the light guide plate from a side adjacent to the diode light emitting module 2. The top surface of the main body 1 is partially extended and covered, which can prevent the light emitted by the light emitting diode 21 from being immediately emitted from the top surface of the light guide plate main body 1 and affect the overall brightness and uniformity of light output of the light guide plate main body. The light guide plate structure of this creation can be further 8 M264520 includes a cold cathode tube 4 provided on the opposite side of the diode light emitting module 2, and the light guide plate body 1 can be recessed with an accommodating space to accommodate the cold cathode tube 4 The reflecting element 3 may extend along a side edge of the bottom of the light guide plate body 1 facing the cold cathode tube 4 and may further extend to a part of the top surface of the light guide plate body i, so that the reflecting element 3 is directed to A top surface portion of the light guide plate body i extends. Furthermore, the reflective element 3 can extend at least and completely cover the remaining two lateral side edges of the light plate body 1 so as to achieve a completely covered reflection effect (as shown in the fourth figure); another implementation of this creation For example, it can also be implemented in two sets of the diode light emitting module 2 provided on the light guide plate body 1 (not shown), and the two diode light emitting modules 2 are provided on the light guide plate body 1 Two opposite side edges (in a flat shape) or two adjacent side edges (in an L-shape), the reflective element 3 can also make the perforation of the light emitting diode 21 corresponding to the two diode light emitting module 2 3 χ, so that the perforation 3.1 may not be limited to only one edge of the reflective element 3. The reflective element 3 can be a reflective sheet, and the reflective element 3 can be attached to the light guide plate body by an adhesive step. As described above, the reflective element 3 can be formed by the light guide plate body. The bottom of 1 extends to two side edges (or four side edges); so, between the bottom surface and the side edge of the light-guiding plate body 1 critically, a reflecting line 3 can be provided between the reflection element 3, To facilitate the pasting step. The above-mentioned formation of the polyline can be formed simultaneously with the perforation 31, so that it can be completed in the same step without waste of time. Another embodiment of the reflective element may be an optical film having a low light transmittance, and the reflective element 3 is plated on the light guide plate body 1 in a manner that reserves the perforation 31 by a coating method; The law system further forms the light guide plate body 1 integrally, and the step of applying 9 M264520 is further reduced. As shown in FIG. 2B, the circuit board 20 of the diode light-emitting module 2 is disposed parallel to the side edge of the light guide plate body 1, that is, the light-emitting diode 21 is disposed in a lay-down manner.
