Abstract

The invention provides a color filter which comprises a plurality of repetitive pixel units, wherein each pixel unit comprises 8 pixels, each pixel comprises a square R subpixel, a square G subpixel and a square B subpixel, the R subpixel, the G subpixel and the B subpixel are arranged in an L shape or an inverted L shape in each pixel, and the plurality of pixels are arranged in a complementary manner, so that the subpixels with the same color are adjacent.

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...
