Description

【Technical field】 [0001] The invention relates to a liquid crystal display device, in particular to a liquid crystal display device using wide viewing angle technology. 【Background technique】 [0002] The liquid crystal itself in the liquid crystal display device does not have luminescent properties, it uses an electric field to control the twisting of the liquid crystal molecules to pass or not to pass light, so as to achieve the purpose of display. In a traditional liquid crystal display device, electrodes are formed on the surfaces of two glass substrates to form an electric field that controls the twisting of liquid crystal molecules. The electrodes use transparent materials, and the electrodes of the two substrates are oppositely arranged to form an electric field perpendicular to the surface of the substrates. . Because the liquid crystal molecules have electrical properties, under the control of the electric field, the orientation of the liquid crystal molecules will...

Problems solved by technology

[0004] Since the IPS type liquid crystal display device 1 cannot utilize ambient light to provide illumination for the display, the display of the liquid crystal display device 1 needs to rely on the illumination emitted by its backlight module (not shown), because the backlight module is the entire liquid crystal display device. The main energy-consuming device of the LCD device accounts for about half of all energy consumption. If only relying on the backlight module to provide lighting and cannot use ambient light sources to provide lighting, the energy consumption of the entire LCD device will increase, which is not conducive to energy saving

Moreover, when the liquid crystal display device is placed in an environment with strong external light, the brightness and contrast of the liquid crystal display device will decrease, so the display quality of the liquid crystal display device is greatly affected by the external environment. In order to maintain the brightness of the liquid crystal display device If the degree and contrast ratio are high, the power of the backlight module must be increased, and the power consumption of the liquid crystal display device will also increase accordingly.
