V. Description of the Invention (丨) [Field of the Invention] The present invention relates to a backlight module and a backlight module on a light source of a display. [Background of the invention] Wang Yaotong's liquid crystal display for panel displays cannot itself emit light, but it can be easily adjusted by the transmission of light, with the help of a light source like a backlight module. Backlight modules are usually divided into two types, one of which is a bottom light source type in which the light source is arranged next to the liquid crystal display to illuminate the entire substrate; the other is a side light source type which is arranged in at least one side of the substrate, and the light is positioned against the light guide or Mirror reflection and diffusion. Recently, a side light source type backlight module is mainly used. In addition, the side-light type backlight module has a lower shell than the bottom-light type, so two sets of mirrors 1¾ are needed to collect the light source, so that the lower brightness can be compensated to a specific level. The conventional technology of the backlight module is shown in FIG. 丨. A fluorescent lamp 1 like a linear light source and a lamp reflector 2 reflecting light from the fluorescent lamp 1 are arranged on one side of the light guide 3. The light guide 3 The light from the light lamp 丨 is transmitted into the planar light source, and another reflector 4 is arranged under the light guide 3 to avoid light leakage. A diffuser plate 5 is disposed on the light guide 3 and uniformly diffuses the light source ' and a mirror group 6, 7 having a plurality of linear hinge lenses is disposed on the diffuser plate 5. The two articulator groups 6, 7 are arranged so that the linear mirrors 8, 9 are perpendicular to each other, so that light of different directions can be collected in a single direction or a direction perpendicular to the light guide 3. -. ^^^. · ----- tri J ------ ^ —-(Please read the precautions on the back before filling out this page) Printed by the staff of the Intellectual Property Bureau of the Ministry of Economic Affairs Applicable to China National Standard (CNS) A4 specification (210 X 297) — 525028 Printed by A7, Consumer Cooperatives, Intellectual Property Bureau of the Ministry of Economic Affairs. 5. Description of the invention (α) However, according to the conventional backlight module, the diffuser plate 5 The two mirror groups 6 and 7 are formed on the light guide 3, so the production procedure is complicated, and the yield is also low. Because of this, the inventor was based on the spirit of positive invention, and considered a kind of "backlight module" that can solve the above problems. After several research experiments, he finally completed this invention that benefits the world. [Summary of the present invention] The main object of the present invention is to provide a backlight module, which can increase the light emission brightness of the backlight module. A secondary objective of the present invention is to increase the output of the backlight module. In order to achieve the above object, the present invention provides a backlight module including a light source for emitting light; a light guide for guiding light to be transmitted from the light source in a first direction; A mirror pattern is provided, and a reflector is provided under the light guide, and the reflector reflects light emitted in a second direction opposite to the first direction to the first direction. In the same light module, the articulation patterns are arranged close to each other, and the preferred shape is a pyramidal recess. The backlight module further includes a diffusion region, and is close to the surface mirror pattern of the light guide. At the same time, the 绾 backlight module further includes a light source reflector surrounding the light source, and the light is reflected by the light source and collected into the light guide through the notch. .Loan -------: ----- Shang. · ----- Order —.------ ^ 9.— (Please read the notes on the back before filling this page) _ 525028 A7
