The existing solution is to add a linear prism array between display units, and to refract light rays emitted from two sides of the seam by the prisms, so as to realize visual seamless display.
An Organic Light-Emitting Diode (OLED) is a display screen made of Organic electroluminescent diodes. Organic electroluminescent displays are considered as an emerging application technology for flat panel displays of the next generation because of their excellent properties such as no backlight source, thin thickness, high contrast, light viewing angle, fast reaction speed, wide temperature range for use, simpler structure and process. Achieving seamless tiling of OLED display screens is a problem to be solved by those skilled in the art.
