[0017] Next, please refer to FIG. 2 , which shows a schematic view of the first embodiment of the present invention. As shown in the figure, the light source module of the present invention is suitable for a flat panel display, and includes a lamp assembly 200 , a reflector R and a diffuser G. The lamp assembly 200 includes a lamp 10 and a light-transmitting element 20 , and the lamp 10 is a cold cathode lamp (CCFL) disposed between the reflector R and the diffuser G. The surface of the reflector R is provided with a reflective material to reflect light. In addition, a panel (not shown) is arranged above the diffuser G for displaying images.

[0018] Generally speaking, a plurality of lamp tubes 10 arranged in parallel can also be set in the light source module, wherein the light emitted by the lamp tubes 10 can be reflected by the reflector R and pass through the diffuser G, or directly pass through the diffuser G and emit upwards. , to provide the brightness required by a f...

Abstract

The invention is a light source module, comprising a reflecting plate, a diffusing plate, a tube and a light transmitting component, where the tube is situated between the reflecting and diffusing plates. Besides, the light transmitting component is coated on the tube, and a light emitted from the tube is refracted by the light transmitting component and then passes through the diffusing plate.

Description

technical field [0001] The invention relates to a light source module, in particular to a light source module suitable for a flat panel display, which can improve the phenomenon of uneven brightness caused by existing lamp tubes. Background technique [0002] With the improvement and improvement of flat panel display manufacturing technology, a liquid crystal display (Liquid Crystal Display, LCD) with the characteristics of small size and low radiation has gradually replaced the traditional cathode ray tube (Cathode Ray Tube, CRT) display in recent years. Generally speaking, the light source module of the liquid crystal display mostly adopts a strip-shaped lamp as a light source, such as the existing cold cathode fluorescent lamp (Cold Cathode Fluorescent Lamp, CCFL). [0003] First, please refer to FIG. 1 , which is a schematic diagram showing an existing light source module. As shown in the figure, the existing light source module mainly includes a lamp tube 10 , a reflec...
