Problems solved by technology

When the sub-pixel pitch is reduced and the transport performance of the functional layer is continuously improved, the lateral current of the display panel is also increased, resulting in crosstalk, that is, when one of the sub-pixels (the target sub-pixel) is lit, a small number of holes can It is injected into the adjacent sub-pixel through the transport fu

Abstract

The invention discloses a WOLED display panel which includes a TFT array substrate and also includes a color filter layer and a light emitting structure layer orderly arranged on the TFT array substrate, wherein the light emitting structure layer comprises an anode layer, a pixel defining layer, a white light organic light emitting layer and a cathode layer arranged in order. The pixel defining layer comprises pixel opening parts and pixel spacing parts for spacing two adjacent pixel opening parts, each of the pixel spacing parts is provided with a protruding insulating spacer, and the white light organic light emitting layer correspondingly covers a part of the spacer to form a protruding deflection part. The invention also discloses a display device with the above WOLED display panel.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to a WOLED display panel and a display device. Background technique [0002] Organic light emitting diode (Organic Light Emitting Diode, OLED) has the characteristic of self-illumination. It adopts very thin organic material coating and glass substrate. When the current passes through, the organic material will emit light, and the organic light emitting diode display screen has a large viewing angle. , and can significantly save power, so organic light-emitting diodes are now more and more widely used. [0003] The core component of an OLED display device is an OLED display panel. The structure of an OLED display panel usually includes: a TFT array substrate, an anode layer sequentially fabricated on the TFT substrate, a pixel definition layer, a first common layer for transporting holes, and a light-emitting layer. , a second common layer for transporting electrons, and a cathode...
