Problems solved by technology

Because the recombination of holes and electrons will generate heat at the same time, the increase in temperature will reduce the efficiency of fluorescent light, and the color coordinates of white light will also change.
[0004] In addition, the color filter block in the liquid crystal display panel absorbs unnecessary colors in white light, and only allows the corresponding red, green or blue light to pass through, which will reduce the utilization rate of light

Abstract

The invention discloses a liquid crystal display device, relating to the field of colour liquid crystal display device. The invention solves the technical problem of providing a liquid crystal display device. The liquid crystal display device comprises a liquid crystal display panel which is provided with a plurality of first fluorescence blocks and a plurality of second fluorescence blocks; and a backlight which provides blue light area light source to the liquid crystal display panel. The first fluorescence blocks product red light under the irradiation of blue light, and the second fluorescence blocks product green light under the irradiation of blue light.

Description

【Technical field】 [0001] The invention relates to a liquid crystal display device, in particular to a color liquid crystal display device. 【Background technique】 [0002] Liquid crystal display technology has been greatly developed in recent years, and liquid crystal display devices have gradually replaced bulky CRT display devices. Lightweight and energy-saving electronic devices is a common requirement in today's society. Therefore, making display devices thinner, lighter and more power-saving is the direction of continuous efforts of manufacturers. At present, using light-emitting diodes as light sources of liquid crystal display devices to replace cold cathode fluorescent tubes is a way to make liquid crystal display devices light, thin and energy-saving. figure 1 A schematic top view showing a color liquid crystal display device in the prior art; figure 2 A schematic cross-sectional front view of a color liquid crystal display device in the prior art is shown. Such ...
