Description of the invention (丨) [Field of the invention] The present invention relates to a method and a structure for shading the edge of a display, which is a shading method using an optical film, especially an optical film suitable for a flat display. Light-shielding method and the optical film. [Background of the Invention] In recent years, flat panel displays have attracted the attention of the display market due to their advantages of lightness, thinness and shortness. Flat-panel displays (such as liquid crystal displays) that do not emit light by themselves often rely on an optical module with a light source, and the optical module usually contains an optical film and a light guide plate. However, in order to cooperate with the optical film to avoid the leakage of light from the edge of the display area of a flat panel display (such as a liquid crystal display), the quality of the display is deteriorated. Black ink is usually printed on the periphery of the film to absorb light leakage from the edges. However, this method of printing black edges on the optical film with ink requires special equipment to dry the ink, which makes the cost of the equipment high. In addition, ink printing is easy to cause environmental pollution, and printing and drying (the process is time-consuming and inefficient. In recent years, due to the advancement of materials and functions of optical films, there have been several advanced optical films that cannot or cannot be easily printed. Mode plus a light-shielding film, so the industry has been seeking an improved processing method for the light-shielding method of this optical film, and urgently needs a light-shielding method and optical film of the optical film that can be processed quickly without special processing equipment. 'Based on the spirit of active invention, we are thinking about a "display edge shading method and structure" that can solve the above problems. After several research experiments, this invention has been completed.

Description of the invention ([Summary of the invention] Main purpose —. ^ A shading method for the edge of the display "^ Dan Pan & Shading method, can be easily processed, and the equipment is convenient, saving processing time Cost. The secondary purpose of the present invention is to provide a method and structure for shading the edge of a display, which is a shading method using an optical film, which can be applied to any optical film, quickly achieve the function of shading, and can increase the light. Utilization. Another object of the present invention is to provide a display edge shading method and structure, which is to use an optical film, which can quickly achieve the function of shading and increase the utilization of light. In order to achieve the above purpose, The display edge shading method and structure of the display of the present invention include the following steps: first providing an optical film; and attaching a layer having a light absorbing surface and a light reflective surface on at least part of the peripheral surface of the optical film. A light-shielding film, wherein the light-absorbing surface on the light-shielding film faces away from the light source. The edge light-shielding structure for a display of the present invention is attached to at least a portion of the peripheral surface of an optical film with a light-absorbing surface, and Light-shielding film with light-reflective surface, wherein the light-absorbing surface on the light-shielding film is facing away Source.

Description of the Invention (Evening) 苐 1 The picture shows the film of the invention and the learning film [Illustration of the drawing number] 11 〇 Optical film 20 long light-shielding film [Detailed description of preferred embodiments] The optical thin film suitable for the present invention is a light diffuser (diffuser), optical film, preferably light Diffusion layer. A layer suitable for the present invention: preferably a device with a prism surface, preferably a liquid crystal display. Applicable Custom = Any light absorbing surface, preferably black surface. _ The i-side and the retractable surface of the present invention can be any light-reflective surface, preferably a white surface reference f ° light-editing film attached to the optical film, which can be any part of the periphery, preferably j-attach first learn_ 的All materials. The optical film can be any optical thin boat, preferably a transparent optical film with heat resistance. In order to make the members of Beibei Committee better understand the technical content of the present invention, the preferred embodiment of the light shielding method of the optical film is described as follows. Please refer to FIG. 1. FIG. 丨 is a schematic diagram of a transparent optical film with high light transmittance according to the present invention. At least one layer of light-shielding film is attached to the edges of the optical film in the i-th figure. The long light-shielding film has a black and white surface, one surface is all black, and the other surface is all white. The black surface is used to absorb light, and the white surface is used to reflect light to increase the usability of light. When the long-type light-shielding film is attached to the optical film, it is based on L______5. This paper size is applicable to China National Standard (CNS) A4 specifications. 〇x 297 Public Love 5. Description of the invention (4) The light source is the principle. It is better to attach the black surface to the surface of the two sides of the membrane. The square surface and the white surface are naturally facing away from the film. This is just one of the four examples. The reverse is also possible. '. 7 Therefore, when the button is assembled into an optical module and a group, the white surface of the long light-shielding film is from ...: toward the surface of the light guide plate of the optical module, the long light-shielding film is more colored = Erran is facing the back of the light-guide plate- square. The 2 version of the thin version used in this preferred example has good heat resistance and softness, which can avoid changes in properties caused by long-term contact with the light source and heat generation from the light source. The attaching in this embodiment is completed by applying a transparent adhesive layer to the long-type light-shielding film, and then attaching it to the optical surface by pressure. In general, when the light source of an optical module is illuminated, the light from the light source is emitted by the light guide plate through the light guide plate and is provided to the light source of the flat display panel, and the light will be attached to the edge of the light guide plate (or the edge of the display area) due to the invention. The function of the long-type light-shielding film U film is to leak light at the edge that passes through the display area and is located outside the display area. It will be absorbed by the W-colored surface of the long-type light-shielding film of the optical film and located outside the display area. Edge light will also increase the reuse of light due to the highly reflective effect of the white surface of the long light-shielding film to increase the brightness of the optical module. Since the method of the present invention is to attach the light-shielding film by the method of attaching, there is no problem that the ink pollutes the environment, and no special equipment is required for re-drying, so the cost of the special equipment and the time of the drying process can be saved, and the effectiveness. Because of the use of a long light-shielding film with black and white surfaces, light absorption (light-shielding) and reflection can be achieved to improve the light reuse rate. And because the method of the present invention is simple and convenient, it can be applied to 480349 A7 V. Description of the invention (Even) An optical film that uses elasticity compared with the previous technology, and there is no need to elaborate on the progress. To sum up, the present invention, regardless of the purpose, means and effect, shows its characteristics that are quite different from the conventional technology. It is a "breakthrough in the method and structure of the display edge shading." Granting a quasi-patent, 'Benefit society, hold your heart — I will do it.
