Problems solved by technology

However, after light color filtering, the luminance of each color light source will only be less than 20% of that of the original white light source
Not only will it affect the overall display brightness of the liquid crystal display device 200, but it will also cause power consumption of the liquid crystal display device 200, which is not conducive to applying the liquid crystal display device 200 to a portable electronic product

Embodiment Construction

[0041] First, see figure 2 and image 3 Shown are a schematic cross-sectional view and a perspective view of a partial structure of a preferred embodiment of the present invention, respectively. As shown in the figure, the liquid crystal display device 400 of the present invention is mainly provided with at least one organic electroluminescent device 30 on the liquid crystal panel 40 , and uses the organic electroluminescent device 30 as a backlight source of the liquid crystal display device 400 .

[0042]Wherein, the liquid crystal panel 40 includes a first polarizer 41 , a liquid crystal layer 45 and a second polarizer 49 . Of course, a thin film transistor array (TFT Array) 43 may also be disposed on the liquid crystal layer 45 to form a TFT liquid crystal display device. Moreover, the liquid crystal material inside the liquid crystal layer 45 can also be selected differently according to different directions in which the liquid crystal display device 400 is used. For ...

Abstract

The invention discloses a liquid crystal display device, especially relates to a liquid crystal display device with organic power excitation light emitting components as back light source. The liquid crystal panel is provided with at least a first organic power excitation light emitting component for generating red light source, at least a second organic power excitation light emitting component for generating green light source, and at lease a third organic power excitation light emitting component for generating blue light source, realizing pixel definition according to liquid crystal panel settings, and realizing liquid crystal display device full colorful display without color filters.

Description

technical field [0001] The invention relates to a liquid crystal display device, especially a liquid crystal display device using an organic electroluminescence component as a backlight source, thereby saving the setting of a color filter. Background technique [0002] With the continuous progress of the electronic industry, some traditionally bulky electronic products have gradually evolved to be portable. Reflecting on the display device, the liquid crystal display device (LCD) replaces the traditional cathode ray tube (CRT) display device and becomes the mainstream in the market. For some electronic products that are carried by individuals, such as mobile phones, PDAs, and notebook computers, it is even more impossible to use traditional CRT display devices as display interfaces. [0003] Press, the liquid crystal display device (LCD) of general prior art, such as figure 1 As shown, the liquid crystal display device 200 uses a white light source as the backlight source ...
