Abstract

The invention provides a device11 for removing display pixel particle effect, which comprises an optical lens device 01 and a scattering device 02. The optical lens device 01 covers the front of a display pixel group 12 of an OLED (organic light emitting diode) display screen, the scattering device 02 is arranged in front of the optical lens device 01, and the optical lens device 01 is used for refracting light emitted from the display pixel group 12 to the surrounding. The invention further provides an OLED display screen, which comprises at least one OLED display module 13, a signal driving circuit 14, a power source 15, a fixing bar 16, a backing plate 17 and the device 11 for removing the display pixel particle effect. By the device for removing display pixel particle effect, the pixel fill rate is increased, the display pixel particle effect of the OLED display screen is removed, and excellent visual experience can be brought to viewers.

Description

technical field [0001] The invention relates to a device for eliminating grain effect of display pixels and an OLED display screen, belonging to the field of display technology. Background technique [0002] The OLED ultra-high resolution display wall provides a unified information display platform, and is currently widely used in electric power, transportation, energy, telecommunications, military and public security, enterprises, radio and television, etc. [0003] OLED is a self-luminous material that does not need a backlight panel. It also has a wide viewing angle, uniform image quality, fast response speed, easy colorization, and can achieve light emission with a simple driving circuit. The process is simple and can be made into a flexible panel. Based on the principle of light, thin and small, the scope of application belongs to small and medium-sized panels. In terms of display: active light emission, wide viewing angle range; fast response speed, stable image; high...
