Chromaticity adjustment method of liquid crystal display device, liquid crystal display device and terminal equipment

Abstract

The invention discloses a chromaticity adjustment method of a liquid crystal display device, a liquid crystal display device and a terminal device. The chromaticity adjustment method of a liquid crystal display device includes a liquid crystal display device including a backlight source and a liquid crystal display panel located on the backlight source, and the liquid crystal display panel Including the color filter layer, the chromaticity adjustment method includes adjusting the transmittance at the maximum light intensity of the blue emission spectrum peak of the backlight corresponding to the transmission spectrum of the blue color resistance in the color filter layer; wherein, the adjusted color filter layer The ratio of the transmission spectrum of the medium blue color resistance corresponding to the maximum light intensity of the blue emission spectrum peak of the backlight to the maximum transmittance of the transmission spectrum of the blue color resistance in the adjusted color filter layer is less than 0.84. Compared with the prior art, the technical solution of the present invention reduces the transmittance of the blue color resistance to blue light in the color filter layer, and improves the blue color while improving the yellowing problem of the liquid crystal display device caused by the photoalignment film. dominant wavelength of the backlight.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a method for adjusting chromaticity of a liquid crystal display device, a liquid crystal display device, and a terminal device. Background technique [0002] For liquid crystal display devices, the traditional rubbing alignment technology will reduce the contrast of the liquid crystal display device and reduce the display quality of the liquid crystal display device. The photo-alignment technology is widely used because it can solve the problems of rubbing alignment, but the photo-alignment film is not transparent to blue light. The low pass rate makes the chromaticity of the liquid crystal display device yellow.

[0002] For liquid crystal display devices, the traditional rubbing alignment technology will reduce the contrast of the liquid crystal display device and reduce the display quality of the liquid crystal display device. The photo-alignment technology is widely used because it can solve the problems of rubbing alignment, but the photo-alignment film is not transparent to blue light. The pass rate is low, making the chromaticity of the liquid crystal display device yellow

[0003] In order to solve the problem of yellowing of the chromaticity of the liquid crystal display device caused by the photo-alignment film, it is necessary to adjust the transmittance of the color filter layer to red light, green light, and blue light at the same time. During the adjustment process, it is necessary to improve the color filter layer to blue light. However, the increase of the blue light transmittance of the color filter layer will lead to a decrease in the dominant wavelength of the blue backlight, making it difficult to meet the requirements of the display device for the blue dominant wavelength
