Problems solved by technology

[0004] Compared with red light and green light, the wavelength of blue light is closer to the wavelength of ultraviolet light. Therefore, the blue light fluorescent layer is easily affected by ultraviolet light. Under the environment of higher temperature and direct ultraviolet radiation, the luminous efficiency of the blue light fluorescent layer will be affected, thus Reduce the luminous intensity of blue light, and the RGB three primary colors are mixed with different luminous intensities to make the display effect poor, which in turn affects the display effect of the plasma display device

Abstract

The invention relates to plasma display device. It includes an up base board and a down. The up base board is set transparent dielectric layer, display electrode, sweeping electrode, and protecting layer. One side of the down opposed to the up is set address electrode, red, green, and blue light fluorescent layer which set optics units includes the first and second units made up of high refractive index film and low whose root thickness is lambada / 4n1, lambda / 4n2 that lambda is reference wavelength; n1 is the refractive index of the high refractive index film; n2 is the refractive index of the low.

Description

【Technical field】 [0001] The invention relates to a plane display device, especially a plasma display device. 【Background technique】 [0002] In recent years, flat panel display devices have developed rapidly and have been widely used in fields such as personal computers, mobile communications, and consumer electronics, becoming a major platform for information technology. Currently, flat panel display devices commonly used include plasma display device (PDP), liquid crystal display device (LCD) and field emission display device (FED). Among them, compared with other flat display devices, the plasma display device has the advantages of thin thickness, light weight, uniform brightness of the display screen, fast response speed, wide viewing angle, high resolution and no X-ray radiation, etc., and it is easy to make a completely flat super large Display screen (40 inches and above). [0003] The plasma display device is a display device that uses gas discharge. The display s...
