Problems solved by technology

However, the control circuit of the non-light-emitting area needs to use a fixed area, so compared to the red-green-blue OLED display shown in Figure 2A, the red-green-blue-white OLED display shown in Figure 2B has less light-emitting area and lower aperture Rate

Embodiment Construction

[0068] FIG. 3 shows a pixel structure of an OLED display disclosed in the first embodiment of the present invention, wherein a pixel 3 of the OLED display includes a first sub-pixel region 31 and a second sub-pixel region 32 . The first sub-pixel area 31 has a first OLED 33 but no control circuit, and the second sub-pixel area 32 has a second OLED 34 and a control circuit 35 . The control circuit 35 has a first control circuit portion 35a and a second control circuit portion 35b. The first control circuit part 35 a includes electronic components for controlling the first OLED 33 , and the second control circuit part 35 b includes electronic components for controlling the second OLED 34 .

[0069]In this embodiment, the luminous efficiency of the first OLED33 can be lower than that of the second OLED34. For example, the first OLED33 can be a blue OLED, and the second OLED34 can be a red, green or white OLED. The first control circuit part 35a is arranged in the second sub-pixe...

Abstract

Systems for emitting light incorporating pixel structures of organic light-emitting diodes (OLEDs) are provided. A representative system comprises: a first sub-pixel area including a first OLED; and a second sub-pixel area including a second OLED and a second control circuit, wherein said second control circuit includes electronic components for controlling said first and second OLEDs.

Description

technical field [0001] The present invention relates to an organic light-emitting diode (OLED). Background technique [0002] An organic light emitting diode (OLED) display is a flat-panel display capable of emitting light by using an organic compound as a light-emitting material. The OLED display has the advantages of small size, light weight, wide viewing range, high contrast, and high response speed. [0003] FIG. 1 shows a sub-pixel (sub-pixel) 11 of a conventional OLED display. The OLED display includes a plurality of pixels, and each pixel includes a plurality of sub-pixels 11 . The power line 12 , the data line 13 and the scan line 14 are also shown in FIG. 1 , wherein the sub-pixel 11 includes a light-emitting area 15 and a non-light-emitting area 16 . [0004] The light-emitting area 15 includes an OLED capable of converting electrical energy into light energy, and the OLED is composed of organic compound thin films. The non-light-emitting area 16 has a control ci...
