Problems solved by technology

[0011] However, since the production of the color filter film requires multiple processes, it is relatively cumbersome, and the price is not cheap, so the overall price of the liquid crystal display cannot be further reduced.
In addition, because the arrangement of the color filter film and black matrix ...

Embodiment Construction

[0031] figure 2 It is a schematic structural diagram of a backlight module according to a preferred embodiment of the present invention. The backlight module 200 is composed of a surface light source 210, a light-shielding matrix 220, and a phosphor layer 230. Wherein, the surface light source 210 is composed of a light guide plate 212, a line light source 214 and a reflection cover 216. The light guide plate 212 is, for example, a wedge-shaped light guide plate, which has a light incident surface 212a, a light diffusion surface 212b, and a light exit surface 212c, and the light diffusion surface 212b has a plurality of V-shaped notches (visible in the figure Area A). The reflection cover 216 is disposed beside the light incident surface 212 a, and the line light source 214 is disposed in the reflection cover 216. The aforementioned linear light source 214 is, for example, a cold cathode fluorescent lamp (CCFL) suitable for providing white light or a light emitting diode array. ...

Abstract

The invention relates to a backlight module group, adaptive to provide a colorized plane light source, and mainly composed of a plane light source, a shading matrix and a fluorescent layer. Where, the shading matrix is on the surface of the plane light source and has many grid points exposing the plane light source, and the fluorescent layer is distributed in these grid points. Thus, the fluorescent layer colorizes the lights emitted from the plane light source. In addition, it also provides a LCD, mainly composed of the above backlight module group and a LCD panel, which is composed of an array basal plate, an opposite basal plate and a liquid crystal layer, where the opposite basal plate is above the array one and the crystal layer is between the two ones, and which is above the backlight module group.

Description

Technical field [0001] The present invention relates to a backlight module (Back Light Module) and a liquid crystal display (Liquid Crystal Display, LCD), and in particular to a backlight module that can provide a colored surface light source and the application of the backlight module Set of LCD monitors. Background technique [0002] In order to match the modern lifestyle, the size of video or imaging devices is becoming thinner and lighter. Although the traditional cathode ray display (CRT) still has its advantages, due to the structure of the internal electronic cavity, the display is bulky and takes up space, and there are still problems such as radiation damage during display. Therefore, flat panel displays, such as liquid crystal displays (LCD), organic light emitting displays (OLED), or plasma displays (Plasma Display Panel, PDP) developed by optoelectronic technology and semiconductor manufacturing technology, have gradually become displays The mainstream of the product....
