Description of the new type: [Technical field to which the new type belongs]-Species =! There =: Species of light guide plate reflection structure, especially the reflection of 70 pieces to the light guide plate on the ship by combining the light ^ [previous technology] Lu and Fei can provide products—a kind of components for the back light source. At present, r τ rm 念 口 # w Yuejia produces mouth, such as LCD monitors, films, slides, projectors and other products. The backlight component of the display is the largest market. In recent years, with the rapid development of the industry, the backlight module market has also grown rapidly, and has become one of the most sought-after products in the upstream and downstream component industry. Parts, how to save the raw material cost of the backlight module, shorten the assembly process, and improve the production efficiency are the top priorities in the backlight module industry. The main components of the backlight module include a light source, a light guide, a reflective sheet, a diffuser sheet, a sheet, a pnsm sheet, and a light-enhancing sheet. Enhancement Film). The principle is simply a light guide plate that introduces spontaneous light sources, such as lamps (CCFL), light emitting diodes (LEDs), etc., to produce a larger and more uniform light exit surface; among them, the reflection sheet provides spontaneous After the light emitted by the light source is reflected, it is emitted on the light emitting surface of the light guide plate, which has the advantages of light weight, high brightness, good light emitting angle, high light utilization efficiency, and simplified structure. Generally, in the process of assembling the backlight module, the spontaneous light source is usually faced to the light guide plate, except for the light guide surface M272114 of the light guide plate, which is covered with a reflective sheet, which 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 the light emitting surface of the light guide plate. Please refer to the first conventional light guide plate structure shown in FIG. 1A and FIG. 1B, which includes a light guide plate body 1 a, and a bipolar light emitting module 2 disposed on a side edge of the light guide plate body a _. a, and a reflective sheet 3 a covering the bottom surface of the light guide plate body, a; or further comprising a cold cathode tube 4 a provided on the opposite side of the diode light emitting module 2 a to maintain the light guide plate body light uniformity of φ 1 a; and the reflecting sheet 3 a further extends from the bottom surface of the light guide plate body 1 a toward the diode light emitting module 2 a and the cold cathode tube 4 a to cover it, or further The light guide plate body 丄 a is covered to the upper surface of the portion; further, the light guide plate body 1 a can be recessed into a valley space to accommodate the cold cathode tube 4 a; thereby forming a conventional light guide plate structure. In order to further combine with optical elements such as a diffuser and a polarizer to form a backlight module. The diode light emitting module 2 a includes a circuit board 20a and a plurality of light emitting diodes # 2 1a arranged on the circuit board 20a; in order to avoid the light emitting diode 2 1 The light of a is absorbed by the circuit board 20a when it is emitted (the degree of absorption depends on the circuit board 20a. The material itself and its reflectance are the light transmitted to the light guide plate 1a. There is a certain degree of impairment), before the diode light-emitting module 2 a is assembled to the side light guide plate body 1 a, a reflective sheet is pasted on the circuit board 20a to face the light guide plate body 1a in advance. 2 a, in order to reduce the above-mentioned trouble that the circuit board 20 a absorbs light. However, the step of applying the reflective sheet 2 2 a is before the diode light-emitting module 2 a is assembled to the light guide plate body 1 a; therefore, regardless of the design and sheet of the reflective sheet 3 a described in 6 M272114 The number of the reflection sheet 3 a is only one piece, and the entire structure of the conventional light guide plate is completed, which requires at least two steps of attaching the reflection sheet (one is the reflection sheet 2 2 a, and one is the reflection sheet). Sheet 3 a) 'and the above two steps are not actions that can be completed continuously, not to mention the time / good time when the design and number of sheets of the reflective sheet 3 a or the reflective sheet 2 2 a tend to be complicated, which are actually assembled And in operation, there is a risk of wasting labor and reducing efficiency. μ 凊 Refer to the second-known Taiwan New Announcement No. 486101 "Light Guide Plate for Backlight Module" shown in the second figure, which reveals the light guide plate body 1 b, which is installed on the light guide plate body 1 b — the side edge of the cold The cathode tube 4 乜 and the reflective layer 3b sputtered on the bottom surface of the light guide plate body 1b; thereby forming a conventional light guide plate structure to further combine with optical elements such as a cymbal, a diffuser, and the like to form a backlight module. However, the light guide plate 1 b still needs to be covered with additional reflective sheets around it. When used in conjunction with a diode light emitting module, the light emitting module will be assembled before the light guide plate ib is assembled. The circuit board is pre-laid with a reflective sheet; of course, before the diode light-emitting module is assembled to the light-guide plate body 1b or a step, the light-guide plate itself-body 1 b is removed from the diode light-emitting module or The other side edges outside the t covered by the cold cathode tube 4 b must be further covered with an additional reflective sheet to avoid light dissipation. Obviously, the equipment, cost, and time required for the sputtering process are higher than the conventional process of applying a reflective sheet, and it is still unavoidable that the process of applying a reflective sheet must be performed on the side of the light guide plate body 1 b. Of course, in addition to the bottom surface of the light guide plate body 1 b, sputtering can also be performed on the side edge portion, but it is time consuming and labor intensive, which is not enough for the basic requirements of mass production. 7 M272114 The reason is that the author felt the above-mentioned shortcomings. He focused on research and applied the five academic theories, and considered the portability characteristics. Finally, he proposed a rational design that effectively improved the above-mentioned shortcomings.

The characteristics of this creation are: 1. There is no gap between the light guide plate body 1ϋ and the reflection frame 10 to reduce the loss of light transmission, and at the same time avoid the conventional adhesive tape required to cover the reflection sheet. The light absorption problems in the future should be improved to increase the brightness; and the stove core 2, to develop mature injection molding technology to maintain low cost and its competitiveness, and provide light guide and reflection functions, and can further reduce the pollution of the toiletry process. Time, taking into account the simplification of the process and the effect of improving efficiency; 〃 /, is a rare new creative product, very innovative and progressive, Yuanquan meets the requirements for new patent applications, and applies in accordance with the patent law, please The patents in this case shall be investigated and granted in order to protect the rights and interests of creators. The above description is only the preferred and feasible embodiment of this creation, and the patent scope of this creation is not limited. Therefore, any equivalent structural changes made by using this creation manual and the contents of the drawings are equally included in this creation. Within the range of S, join Chen Ming.
