Description of the Invention: [Technical Field] The present invention relates to a liquid crystal display device which is mainly coated with a light source for exciting a fluorescent powder photoluminescence on the surface of a polarizing plate below the bottom of the display panel. A phosphor layer of light of different wavelengths is generated, and the phosphor layer is used to diffuse the light source. [Prior Art] According to the general description, the liquid crystal display device is mainly divided into a liquid crystal panel (2) portion and a backlight module (1) portion, and the liquid crystal panel (2) is also a liquid crystal layer (21). The top and bottom surfaces are respectively provided with upper and lower polarizing plates (22), and the backlight module (1) is provided with a light source (12) corresponding to the illumination diffusing plate (13) in the frame (11) to diffuse the plate ( 13) and the brightness enhancement film (14) refracts the light source (12) to the liquid crystal panel (2), and the main functions of the components are as follows: The liquid crystal is used on the display, mainly relying on the electro-optic effect of the liquid crystal and the characteristics of the polarized light, polarized light The meaning is that the light wave will only vibrate in a plane, mainly by a polarizing filter (the filter is composed of two single filters and optical lenses that are 9 degrees each other); and the liquid crystal layer (21) is The two glass sheets are filled with a liquid crystal material. Since the liquid crystal possesses the properties of viscosity, elasticity, and polarizalility, the characteristics of the polarized light are changed when the electrodes pass. In order for the liquid crystal display to display an image 'the liquid crystal conductors which are arranged at 90 degrees to each other at the top and bottom of the two glass sheets of the liquid crystal layer (21), each intersection is a unit 'transmitted to each unit through the signal, so You can control the display of images. The principle of polarizing plate (22) is to convert natural light that is generally not polarized into polarized light. When there is no polarizing plate (22), light can enter and exit the liquid crystal layer (21) freely, without being affected by the applied electric field, but in the liquid crystal layer ( 21) Upper and lower outer 200813557 After adding polarizing plate (22), the transmission of light can be controlled by an applied electric field, so that the light and dark changes can be visually perceived. The main function of the diffuser (13) (Diffuser) is to make the light source (12) diffuse through the diffusion coating to homogenize the light distribution. The diffuser (13) substrate needs to select a material with high light transmittance. Since the diffusion effect is better, the surface treatment of the diffusion layer is a matter of learning, from the PC material of the industrial embossing of the nameplate to the film material of the diffusion agent or the coating type diffusion material or the composite diffusion material combined with the function of the brightness enhancement film. One is to focus on the flowers and the light scattered. The brightness enhancement film (14) is such that when the light source (12) passes through the lower polarizing plate (22), 50% of the light source (12) is wasted and absorbed, and the principle of using the brightness enhancement film is 50% originally absorbed. Polarized light is reused. However, it can be seen from the above-mentioned components that it is very important to make the display of the liquid crystal display image good. The scattering, dispersion and brightness of the light source (12) are very important; and the existing diffusing plate (13) for distributing the light source (12) is uniform. And the light that will be absorbed, the vibrating light repeats the increase ((4), its production (four) and the material cost of Nanxun's make the backlight film group (1) cost your overall LCD display fiber ~40%, and the complexity of the production process The personnel cost is also relatively high, and the mass production is fast and mass production. In view of the fact that the present inventor is the missing point in the production and implementation of the above liquid crystal display, it is corrected and improved, and (4) in the spirit and philosophy of seeking good, and With the help of professional knowledge and experience, and after many ingenuity and experimentation, the invention was created to make orders.
