Abstract

The invention provides an OLED pixel and a display panel using the same. The OLED pixel comprises three sub-pixel groups. Each sub-pixel group comprises a first sub-pixel and a second sub-pixel, wherein the first sub-pixel and the second sub-pixel share one driving circuit, and the light emitting waveband of the first sub-pixel and the light emitting waveband of the second sub-pixel are complementary. The sum of the light emitting wavebands of the first sub-pixels of the sub-pixel groups is a white light waveband. According to the OLED pixel and the display panel using the same, the sub-pixels are formed by means of the principle of diffraction of light and the combination of white light OLED light emitting bodies, beam splitting pieces and light barriers. Due to the fact that the six kinds of sub-pixels all adopt the white light OLED light emitting bodies, the problem of chromatic aberration caused by different aging degrees of different materials is avoided. Due to the fact that three kinds of sub-pixels are additionally arranged to assist imaging processing, luminous efficiency of the OLED pixel is improved and power consumption is reduced. Due to the fact that the two sub-pixels of each sub-pixel group share one driving circuit, the distinguishability of the OLED display panel is improved.

Description

technical field [0001] The invention belongs to the field of semiconductors, and relates to a color realization method of an OLED (organic light-emitting diode), in particular to an OLED pixel and a display panel using the OLED pixel. Background technique [0002] Organic light-emitting diodes (Organic Light-Emitting Diode, OLED) can be used for flexible panels, use Wide temperature range, simple structure and manufacturing process and other excellent characteristics have attracted widespread attention and are used in flat panel display and other fields. [0003] There are three main methods used by traditional OLEDs to display color images: [0004] 1. Use different luminescent materials to achieve RGB three-color luminescence. However, the disadvantage of this method is that the luminescent materials must be optimized for different colors, and the luminescent layers of different materials have differences in service life. Different aging The degree makes the display colo...
