Problems solved by technology

Therefore, adjust the red, blue, and green brightness values ​​to 3.3 to synthesize a white light value of 10. In practical applications, displays that use OLEDs not only consume more power in white light than in theory, but also display better than other displays in general. Technology's display is dimmer and doesn't have the vibrant colors of other displays

Abstract

The invention discloses a mixed LED illuminant for a display, comprising: a substrate; an epitaxial barrier crystal thin film layer formed on the substrate; pixels: a large number of pixels formed on the epitaxial barrier crystal thin film layer Each pixel includes a first sub-pixel, a second sub-pixel, and a third sub-pixel. The first and third sub-pixels correspond to micro ULEDs and are lit by micro ULEDs. The second sub-pixels correspond to OLEDs and are directly lit by OLEDs. ; LED controller: selectively control the micro ULED on and off; electrical interface matrix layer: directly electrically connected to each OLED. On the premise of combining the advantages of the OLED display, the brightness of the display is improved.

Description

technical field [0001] The present invention relates to LED illuminants. More specifically, the present invention relates to hybrid LED emitters for displays. Background technique [0002] An OLED display is an organic light-emitting display technology consisting of a very thin coating of organic materials and a glass substrate. These organic materials emit light when a charge passes through them. The color of OLED light depends on the material of the organic light-emitting layer, so manufacturers can obtain the desired color by changing the material of the light-emitting layer. AMOLEDs have built-in electronic circuitry so that each pixel is driven independently by a corresponding circuit. OLED has excellent characteristics such as simple structure, self-illumination without backlight, high contrast, thin thickness, wide viewing angle, fast response speed, can be used for flexible panels, wide operating temperature range, and relatively simple structure and manufacturing...
