AI Technical Summary

Problems solved by technology

However, since white light is a wide-spectrum light source, the red light, green light and blue light produced by the color filter are still not saturated enough, which makes the color gamut not high enough
In addition, the filtering of the color filter will cause 50% light loss, thus greatly increasing the power consumption of the electroluminescent display panel

Abstract

A pixel structure of electroluminescent display panel has a first sub-pixel region, a second sub-pixel region and a third sub-pixel region. The pixel structure of electroluminescent display panel includes a first organic light-emitting layer and a second organic light-emitting layer. The first organic light-emitting layer, which includes a first organic light-emitting material, is disposed at least in the first sub-pixel region and the second sub-pixel region. The second organic light-emitting layer, which includes a second organic light-emitting material and a third organic light-emitting material, is disposed at least in the second sub-pixel region and the third sub-pixel region. The first organic light-emitting layer and the second organic light-emitting layer overlap in the second sub-pixel region. The first sub-pixel region and the third sub-pixel region have different cavity lengths.

Description

【Technical field】 [0001] The present invention relates to a pixel structure of an electroluminescent display panel, in particular to a pixel structure of an electroluminescent display panel that does not require a color filter. 【Background technique】 [0002] Electroluminescent display panels (such as organic light emitting diode display panels) are expected to become the mainstream products of the new generation of flat display panels due to their advantages such as active light emission, high contrast, thin thickness and wide viewing angle. The current full-color electroluminescence display panel mainly uses a white light organic light-emitting layer to generate white light, and then uses color filters to filter light to form three different primary colors such as red light, green light and blue light, thereby displaying a full-color display screen. However, since the white light is a wide-spectrum light source, the red light, green light and blue light generated after pa...
