Abstract

The invention provides a backlight module. The backlight module comprises a light guide plate, a circuit board and reflecting bodies, wherein the circuit board has a first light source and a second light source; the first light source can provide illumination to a first area of the light guide plate; the second light source can provide illumination to a second area of the light guide plate; when a light emitting angle of the first light source can cause an illumination effect of the first area to be worse than an illumination effect of the second area, the reflecting bodies are respectively arranged at the left and right sides of the light emitting surface of the first light source for reflecting one part of emitted light of the first light source, so that light of the first light source is collected in the first area to enhance the illumination effect of the first light source on the first area, and the light emitting brightness of the first area and the second area tends to be consistent. The backlight module is provided with the reflecting bodies to improve the uniformity of light emitting brightness in all areas.

Description

Technical field [0001] The present invention relates to a backlight module. In detail, it relates to a backlight module that can improve the overall light-emitting effect of a light-emitting keyboard. Background technique [0002] The keys on the keyboard are marked with identification symbols that represent input commands. When the user presses the keys of the keyboard to operate, the keyboard will input the input instructions represented by the key identification symbols to the computer, so the keyboard is indispensable for the use of the computer One of the instruction input accessories. However, when the keyboard is operated in a dim environment, the user may not be able to see the identification symbols marked on each key on the keyboard, and the user will have difficulty in operating the keyboard at this time. [0003] Therefore, there is the design of a light-emitting keyboard. The existing light-emitting keyboard mainly uses the internal backlight module. The backlight mod...
