Problems solved by technology

However, the spectral line bandwidth of the backlight of the liquid crystal display device is much lower than the color mixing curve of the three primary colors of the imaging. This kind of spectral line color with a narrower half-peak width of the spectral line to simulate the spectral line color with a wider half-peak width will cause liquid crystal display devices Distortion of image color, often showing too green or too red color, although the color gamut of the backlight color of the liquid crystal display device is very wide, but the realism of the image is poor, and people are more suitable for the natural environment of continuous spectrum light There is a big difference compared to

Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] The object of the present invention is to provide a liquid crystal display device with abundant back spectrum lines. In order to achieve this purpose, the width of the back spectrum lines will be improved, Figure 4 It is the spectral line distribution of a typical CCFL backlight, from which it can be seen that the energy of other spectral lines except the red, green and blue three-color lines is relatively low. The way to achieve the increase of the back spectral line width. The specific embodiment of the present invention is to improve the light-emitting source part in the traditional LCD...

Abstract

The invention pertains to liquid crystal display field, provides a backlight system of liquid crystal display apparatus, the system comprises solar energy collectors for collecting outdoor sunshine, and photoconductive tubes connecting the connector and the liquid crystal display apparatus, which input the collected sunshine into the liquid crystal display apparatus. Comparing conventional backlight system of liquid crystal display apparatus, the inventive backlight system of liquid crystal display apparatus uses sunshine as backlight source, which is beneficial to reduce energy consumption ofthe liquid crystal display apparatus; the backlight spectral line is continuous full spectrum of nature, the system has more abundant spectral line, such that the color of the display system approaches to nature color of objects, real color of natural object can be shown greatly, and additionally, human eyes are adaptive to the sunshine to prevent visual fatigue.

Description

technical field [0001] The invention belongs to the display field, in particular to a liquid crystal display device. Background technique [0002] In the natural world where people live, the spectrum of visible light of objects observed by eyes is rich and often continuous. However, for a liquid crystal display device using a common CCFL or LED backlight, the light emitted by the backlight source is discontinuous in several limited spectral bands. The color we see from the LCD TV is the result of mixing the above discontinuous spectral segments. This method is a simplified processing method for complex colors. It can only basically reproduce the original color of the scene. The color of the actual object has a large difference in the spectral composition. figure 1 , figure 2 , image 3 The difference between the reflection spectrum of the natural object of the same color and the display spectrum of the liquid crystal display device is shown respectively. [0003] Most ...
