Abstract

The invention provides a colored color filter which comprises a plurality of repeated pixel units, wherein each pixel unit comprises a plurality of pixels; each pixel includes a subpixel R, a subpixel G and a subpixel B, wherein the subpixel R, the subpixel G and the subpixel B of each pixel are arranged in an L shape or reversed L shape; and a plurality of pixels are arranged in a compensating way, so that the subpixels with the same color can be arranged together.

Description

technical field [0001] The present invention relates to a pixel arrangement of a color filter, and more particularly, to a color filter pixel arrangement for improving the color saturation of a high-resolution, full-color and top-emission organic electroluminescent display. Background technique [0002] Organic light-emitting diodes (OLEDs, or organic electroluminescent devices) have the advantages of wide operating temperature range, low power consumption, wide viewing angle, high contrast ratio, and fast response time, and are called the next generation of flat panel displays. According to the direction of light emission, OLED structures can be classified into bottom emission type and top emission type. The light of the bottom emission type OLED exits from a transparent substrate. Top-emitting OLEDs, on the other hand, use a reflective bottom electrode to allow light to exit through a translucent or transparent top electrode. For active-matrix displays, top-emitting OLED...
