Back light module and liquid crystal display

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....

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 on the substrate is often uneven, the color filter must be covered with a flat layer on the color filter film and black matrix during the production process. (over coating) to achieve the purpose of surface flattening, which will increase the complexity of color filter production, and is also a burden on cost
