Device for eliminating joints of mosaic display screen

Abstract

The invention relates to a mosaic display technology, in particular to a device for eliminating joints of a mosaic display screen. The device comprises mosaic units, wherein the surface of each mosaic unit is provided with an optical film layer which is used for enlarging the light-emitting area of edge pixels to cover a frame zone connected with the edge pixels. The device has the advantages that the filling rate of the edge pixels is adjusted by the optical film layer, and the light covers the frame zone connected with the edge pixels, so that the seamless splicing of the mosaic units is realized.

Description

technical field [0001] The invention relates to a splicing display technology, in particular to a device for eliminating seams of splicing display screens. Background technique [0002] OLED, or organic light-emitting diode, is a current-mode light-emitting device based on organic materials. Due to OLED's self-luminous characteristics, no backlight is required, the panel is thin, low driving voltage, low power consumption, fast response, high contrast, wide viewing angle, wide operating temperature range, good mechanical properties, strong shock resistance, and flexible Display and other excellent characteristics are considered to be the emerging application technology of the next generation of flat panel displays. However, affected by the manufacturing process and yield rate, it is difficult to mass-produce large-size OLED screens. The 55-inch OLED TV launched in the market not long ago is currently the largest OLED screen. However, this size still cannot meet the requir...

Problems solved by technology

However, this size still cannot meet the requirements of large-screen display. In order to increase the display screen size, multiple existing small-size OLED displays can be further combined into a larger-sized splicing display wall.

However, due to the requirements of the production process such as sealing glue and wiring, each OLED module has a certain frame range besides the display area, such as figure 1 As shown, multiple existing small-sized OLED modules are spliced ​​and combined into a large-sized display screen. However, due to the limitation of the manufacturing process, each OLED module has a self-illuminating display area and a frame area that cannot be displayed. The area also includes the sealing area and the wiring area, which will cause areas that cannot be displayed on the screen after the OLED modules are spliced, resulting in incomplete and discontinuous spliced ​​images on the screen, affecting the display and viewing effects

like figure 2 As shown, the size of each pixel in the display area of ​​the OLED module is equal. Due to the existence of the frame, the screen picture is not continuous, which affects the viewing effect.
