Abstract
The invention discloses an LCD backlight module structure. The LCD backlight module structure comprises a support, a circuit board, a backlight source, a prism, reflector plates and a backlight diffusion plate. The support supports the entire backlight module structure, and the circuit board is embedded into the support. The backlight source is placed on the vertical side of the circuit board, and the prism surrounds the backlight diffusion plate by a half. The reflector plates are attached to the two ends of the prism, and the backlight diffusion plate is embedded into the support to be surrounded by the prism. According to the LCD backlight module structure, a light-emitting zone is expanded by diffusing the backlight source through the prism and the reflector plates; the light-emitting effect is more even by the backlight diffusion plate; the side face of a display screen is not likely to leak light, so that the space waste phenomenon is reduced, and the space utilization rate is improved.
Description
Technical field
The invention discloses a kind of back light module unit structure, particularly a kind of LCD backlight modular structure.
Background technology
In the electronics industry, backlight is a kind of form of illumination, is often used in LCD display.Backlight type and front smooth formula difference are that backlight is from side or irradiates behind, and as the term suggests front light is then irradiated from the front.They are used to be increased in the brightness on illuminance in low lighting environment and computer monitor, liquid crystal screen, produce bright dipping to show similar mode with CRT.Backlight module is one of key part and component of panel of LCD, and because liquid crystal itself is not luminous, namely the function of backlight module is well-off brightness and the light source be evenly distributed, can normal show image.
With the lifting of work liquid crystal display manufacturing technology, under the trend of large scale and low price, backlight module is in the market demands considering lightweight, slimming, low power consumption, high brightness and reduce costs, client requires more and more higher to liquid crystal display, liquid crystal display structure becomes increasingly complex, changeable, therefore, on the make can exist for and reach requirement and to complex structure, produce the bad phenomenon of wasting space, material, be unfavorable for the long term growth of business capital.
Summary of the invention
For above problem, the invention discloses a kind of LCD backlight module device structure.For solving the problem of backlight module towards market demand future development, the present invention adopts LCD backlight modular structure, by the double reflection of reflector plate plate and prism, makes backlight light-emitting zone become large, luminous route guides through reflection, light emitting source is put on backlight diffuser plate, then by backlight diffuser plate, makes whole backlight module illumination effect more even, this back light module unit structure is simple, display screen side not easily light leak, reduces space waste phenomenon, improves space availability ratio.
A kind of LCD backlight modular structure, described LCD backlight modular structure comprises support, circuit board, backlight, prism, reflector plate and backlight diffuser plate, described support supports whole back light module unit structure, described circuit board is embedded in support, described backlight is positioned at the vertical side of circuit board, described prism semi-surrounding backlight diffuser plate, described reflector plate is attached to the two ends of prism, and described backlight diffuser plate is embedded in support and is surrounded by prism.
