Problems solved by technology

However, the spectral line bandwidth of the backlight CCFL of the liquid crystal display device is much lower than the color mixing curve of the three primary colors of the image. This kind of spectral line color with a narrow half-peak width to simulate a spectral line color with a wide half-peak width will cause liquid crystal display The distortion of the image color of the device often presents a color that is too green or too red. Although the color gamut of the backlight color of the liquid crystal display device is very wide, the realism of the image is poor, and it is more suitable for people to adapt to the natural light of continuous spectrum There is a big difference in the environment

Embodiment Construction

[0016] 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.

[0017] 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. We can see that the energy of other spectral lines except the red, green and blue three spectral lines is relatively low. The present invention increases the energy of other spectral lines different from the red, green and blue three spectral lines. The light source method realizes the increase of the width of the back spect...

Abstract

The invention pertains to liquid crystal display field, The utility model relates to a liquid crystal display device, comprising a liquid crystal panel and a backlight system, the system comprises a plurality of CCFL lamp tube groups, each group has at least two different lamp tubes. The invention increases backlight spectral line width by increasing luminescent sources of other spectral line different from that of red, green and blue light, has backlight source with wide spectrum, thereby showing approximate real color of natural object, to make it comfortable to observe.

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 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 of the ...
