Problems solved by technology

Although the diffuser can increase the uniformity of light, it can also produce light shading and affect the brightness of the backlight assembly
Usually, one diffuser will block 30% of the light source, which means that the brightness of the light source after passing through the diffuser will only be 70% of the original. If two diffusers are used, more than half of the light source brightness will be blocked. The brightness of the liquid crystal display is greatly affected, so if y

Embodiment Construction

[0030] The invention discloses a low-power backlight assembly. The uniformity of the backlight assembly is increased by means of a fluorescent agent coated on a light guide plate. In addition, the low shading rate of the fluorescent agent can increase the brightness of the backlight assembly and reduce the brightness of the lamp tube. Using current to obtain a low-power backlight assembly, the preferred embodiment of the present invention and its implementation method will be described in detail in the following content.

[0031] image 3 It is a cross-sectional view of the low-power backlight assembly 30 of the present invention. The assembly 30 includes a light guide plate 31 , a lamp tube 32 , a reflector 33 , an aluminum back cover 34 and a plurality of optical films 35 . The light guide plate 31 is a plate structure composed of a bottom surface, a top surface and four sides, wherein the sides are perpendicular to the top and bottom surfaces. The material of the light gui...

Abstract

The invention relates to a low-power backlight component, including a light guide board, a tube and a reflection sheet. The light guide board is of a sheet structure composed of a bottom surface, a top surface and four side surfaces, where the top and bottom surfaces of the four side surfaces are mutually vertical, and the tube is on a side surface of the light guide board and guides the light into the light guide board. The reflection sheet is on the bottom surface of the light guide board and can reflect the incident light into the light guide board, making the light which is guided into the light guide board outgo from the top surface of the light guide board. It coats at least one of the top surface, and the bottom surface /four side surfaces with a layer of fluorescent agent to form a fluorescent layer, where the fluorescent agent can absorb the incident light to make the light stay for a short time and then outgo outwards. Therefore, it has better intensifying property and homogeneous degree, able to reduce the power consumption of the tube.

Description

technical field [0001] The invention relates to a backlight assembly of a liquid crystal display, in particular to a low-power backlight assembly. Background technique [0002] With the rapid progress of thin-film liquid crystal display (TFT-LCD) production technology, and its advantages of lightness, lightness, power saving, and radiation-free, liquid crystal displays are widely used in personal digital assistants (PDAs), notebook computers, digital Cameras, camcorders, mobile phones and other electronic products. Coupled with the industry's active investment in research and development and the adoption of large-scale production equipment, the quality of liquid crystal displays has been continuously improved, and the price has been continuously reduced, so that the application fields of liquid crystal displays have rapidly expanded. However, since the liquid crystal display is a non-luminescent display device, it needs a backlight assembly to produce a display function. ...
