Embodiment Construction

[0026] The invention relates to a full-color electroluminescent display. The electroluminescence display includes a pixel array, wherein each pixel is composed of colored sub-pixels, which includes light-emitting units in a multilayer structure. By increasing the size of the multilayer structure, the light-emitting unit is more likely to age to compensate for the brightness degradation of the color sub-pixels.

[0027] Figure 2A It is a schematic diagram of a multilayer structure used in a full-color electroluminescent display according to an embodiment of the present invention. Figure 2A Approximately an area of ​​one pixel unit is displayed. The pixel unit 200 includes a plurality of sub-pixels 210, 220, and 230 of specific colors. Figure 2A In the illustrated embodiment, three basic colors including red, green, and blue are taken as an example. In this way, at least three sub-pixels with different light-emitting colors are formed in each pixel unit 200, namely, red sub-pixe...

Abstract

The present invention relates to a full-color electroluminescence display, which includes: a pixel area arranged on a substrate; and a plurality of color light emitting units arranged in the pixel area to form a plurality of multi-layer stacks for emitting specific Color light, wherein the material of the color light-emitting units is electroluminescent material, and the multi-layer stacks have at least two different multi-layer stacks to emit two different color light.

Description

Technical field [0001] The present invention relates to a full-color electroluminescent display, and particularly relates to a pixel structure of a full-color electroluminescent display, which can effectively compensate for the attenuation of specific light-emitting colors in the pixel structure. Background technique [0002] In recent years, electroluminescent display technology has attracted many developments and researches in the field of emissive displays. Compared with other types of light-emitting displays such as plasma displays, electroluminescent displays can ensure advantages such as low energy consumption, small size, and high image brightness and sharpness. An electroluminescence display system usually includes a pixel array coupled with a light-emitting device defined by a scan wire and a data wire network. The light-emitting device is, for example, an organic light-emitting device (OLED), which is usually driven by a driving circuit corresponding to each pixel. [0...
