Embodiment 1

[0038] figure 1 It is a schematic structural diagram of a display panel provided in Embodiment 1 of the present invention, figure 2 Another schematic structural diagram of the display panel provided by Embodiment 1 of the present invention.

[0039] This embodiment provides a display panel, including: a plurality of light-emitting units arranged on an array substrate 10, wherein the light-emitting units can emit light beams, and in order to separate the light-emitting units, a pixel definition layer is also included for the pixel definition layer. Separated from a plurality of light-emitting units, specifically, the pixel defining layer separates several pixel areas, and the light-emitting units are arranged in the pixel areas, wherein, in this embodiment, each light-emitting unit includes first electrode layers 20 stacked in sequence , a light-emitting layer 30 and a second electrode layer 40, each light-emitting layer 30 includes a red sub-pixel layer 31, a green sub-pixel...

Embodiment 2

[0056] image 3 It is a schematic structural diagram of a display panel provided by Embodiment 2 of the present invention.

[0057] This embodiment provides a display panel, and the difference from the above embodiments is: in this embodiment, if image 3 As shown, the blue sub-pixel layer 33 is filled with blue dye 302, that is, the blue organic light-emitting material of the blue sub-pixel layer 33 is filled with blue dye 302, and at the same time, the blue dye 302 is distributed in the blue sub-pixel In the end of the pixel layer 33 facing the light-emitting side, that is, the blue organic light-emitting material and the blue dye 302 are layered in the blue sub-pixel layer 33 through centrifugal treatment. Specifically, when the light-emitting direction of the light-emitting layer 30 faces the second electrode layer 40, at this time, the blue dye 302 is distributed in the end of the blue sub-pixel layer 33 facing the second electrode layer 40, that is, the blue dye 302 lay...

Embodiment 3

[0061]This embodiment also provides a display device, specifically a flexible display device, the display device can be an OLED display device and a TV including an OLED display device, a digital camera, a mobile phone, a tablet computer, a smart watch, an e-book, a navigator, etc. Any product or part with a display function.

[0062] The display device includes: the display panel provided by any one of the above embodiments. Wherein, for the structure, function and implementation of the display panel, reference may be made to the specific descriptions in the foregoing embodiments, which will not be repeated here.

[0063] In the display device provided in this embodiment, since in the light-emitting unit of the display panel, the light-emitting layer of the light-emitting layer 30 is provided with a blue pigment layer 301, and the blue pigment layer 301 overlaps with the blue sub-pixel layer 33 in the light-emitting direction, so when the second When there is a voltage drive...

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, wherein each light emitting unit comprisesa first electrode layer, a light-emitting layer and a second electrode layer which are stacked in sequence; and each light-emitting layer comprises a red sub-pixel layer, a green sub-pixel layer and ablue sub-pixel layer, wherein a blue pixel layer is arranged on the light emitting side of the light emitting layer, and the blue pixel layer and the blue sub-pixel layer are overlapped in the lightemitting direction. By virtue of the display panel provided by the invention, the service life of the blue sub-pixel layer is prolonged, so that the technical problem that the service life of the display panel is shortened due to the fact that the service life of the blue organic light-emitting material is shortened caused by high current in an existing display screen is solved.

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] Organic light-emitting diode (Organic Light-Emitting Diode, referred to as: OLED) display screen is a display screen made of organic light-emitting diodes. Since it also has self-luminous organic light-emitting diodes, it does not require a backlight source, has high contrast, and is thin in thickness. , wide viewing angle, fast response, applicable to flexible panels, wide operating temperature range, simple structure and manufacturing process and other excellent characteristics, therefore, OLED display screens are widely used in various display devices. [0003] At present, the OLED display mainly includes a display panel, wherein the display panel includes an array substrate and a plurality of light-emitting units arranged on the array substrate, wherein each light-emitting unit includes an anode, a l...
