[0062] This embodiment provides a display panel, refer to Figure 2A As shown, the organic light-emitting layer 23 includes four sub-pixels, and there are three blue sub-pixels and one red sub-pixel 231 in the four sub-pixels, and the three blue sub-pixels are respectively blue sub-pixel 23a, blue sub-pixel 23c and the blue sub-pixel 23d, at the same time, in order to realize four-color display, a green quantum dot layer 32 is also provided on the light-emitting side of the organic light-emitting layer 23, that is, in this embodiment, the quantum dot layer includes: a green quantum dot layer 32 and a yellow quantum dot layer The quantum dot layer 33 has two quantum dot layers, wherein the green quantu...

Embodiment 3

[0071] image 3 It is a schematic cross-sectional structure diagram of a display panel provided by Embodiment 3 of the present invention.

[0072] In this embodiment, the organic light-emitting layer 23 includes four sub-pixels, and the four sub-pixels have two blue sub-pixels, one green sub-pixel 232 and one red sub-pixel 231, and the two blue sub-pixels are blue sub-pixels respectively. The pixel 23a and the blue sub-pixel 23d, at this time, only the yellow quantum dot layer 33 is provided on the light-emitting side of the organic light-emitting layer 23, wherein the yellow quantum dot layer 33 is used to convert the blue light emitted by the blue sub-pixel 23d into yellow The green sub-pixel 232 emits green light, and the red sub-pixel 231 emits red light, so that the light-emitting unit can generate four kinds of light: red, green, blue, yellow (RGBY).

[0073] Among them, in this embodiment, refer to image 3 As shown, the blue sub-pixel 23a emits blue light, the red su...

Abstract

The invention provides a display panel and a display device. The display panel comprises a plurality of light-emitting units arranged on an array substrate. Each light-emitting unit comprises a firstelectrode layer, an organic light-emitting layer and a second electrode layer which are sequentially arranged on the array substrate in a stacked mode. The organic light-emitting layer includes four sub-pixels, and at least two blue sub-pixels are arranged in the four sub-pixels; a yellow quantum dot layer is arranged on the light-emitting side of the organic light-emitting layer; the yellow quantum dot layer is used for converting blue light emitted by one of the blue sub-pixels into yellow light; or the four sub-pixels comprise at least two red sub-pixels, the yellow quantum dot layer is used for converting red light emitted by one of the red sub-pixels into yellow light. The display panel solves the problems that in the prior art, during three-color display, the color gamut is small, and the overall display brightness is low.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Display screens have been widely used in many fields such as portable electronic devices (such as mobile communication terminals, tablet computers, e-books, and navigation equipment) and large-screen electronic devices. Among them, organic light-emitting diodes (Organic Light-Emitting Diode, referred to as : OLED) has been gradually applied to display screens due to its low power consumption, high color saturation, wide viewing angle, thin thickness, and flexibility. [0003] At present, a display screen using OLED generally includes: a display panel, wherein the display panel includes an array substrate, several light-emitting units arranged on the array substrate, and a thin film encapsulation layer covering the light-emitting units and the array substrate, wherein each light-emitting The unit include...
