Embodiment 1

[0033] The embodiment of the present application provides a display panel, such as figure 2 As shown, the light emitting direction of the display panel is shown by arrows in the figure, and the display panel includes a first electrode 21, a second electrode 23, and an electrode interposed between the first electrode 21 and the second electrode 23. The light-emitting layer 22 is provided with a conductive filter layer a in the first electrode 21 located on the light-emitting side of the light-emitting layer 22 , wherein the transmittance of blue light of the conductive filter layer a is greater than the transmittance of yellow light.

[0034] In this embodiment, the first electrode 21 is an anode, and the second electrode 23 is a cathode. It should be understood that, according to actual production requirements, the anode and the cathode can be interchanged, that is, the first electrode 21 is a cathode, and the second electrode 23 is a cathode. for the anode. In addition, the...

Embodiment 2

[0042] Based on the above-mentioned embodiments, an embodiment of the present application also provides a display panel, in which the light-emitting layer is a stacked structure including at least two pixel layers; in addition, adjacent pixels disposed on the light-emitting layer A connection electrode between the layers, wherein a conductive filter layer is arranged in the connection electrode.

Abstract

The present application relates to the field of display technology, and in particular to a display panel and a display device, which are used to solve the problem in the prior art that the display screen of the display panel turns yellow under low power consumption. The display panel includes a first electrode, a second electrode, and a light-emitting layer. A conductive filter layer is arranged in the first electrode on the light-emitting side of the light-emitting layer, and the blue light transmittance of the conductive filter layer is greater than that of yellow light. Light transmittance. In this application, the conductive filter layer is arranged in the first electrode corresponding to the light-emitting direction of the display panel. Since the blue light transmittance of the conductive filter layer is greater than the yellow light transmittance, when the light passes through the first electrode, it will pass through the first electrode. The blue light is more than the yellow light, which makes the color of the outgoing light through the conductive filter layer more balanced. Ensure that the proportion of blue light and yellow light in the light emitted by the first electrode is closer to the balance of color harmony, balance the overall display tone of the display panel, and improve the problem of yellowish picture in the prior art due to the large proportion of yellow light.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] For existing electroluminescent display panels, such as figure 1 As shown, it often includes an anode 11 , a cathode 13 , and a light emitting layer 12 . The light emitting layer 12 is interposed between the anode 11 and the cathode 13, and the light emitting layer 12 may include red pixels, green pixels and blue pixels. The anode 11 provides holes for the light-emitting layer 12, the cathode 13 provides electrons for the light-emitting layer, and the light-emitting layer 12 emits light during the recombination process of electrons and holes. [0003] In the prior art, the electroluminescent display panel often needs to be started at a relatively high voltage. When there is a relatively high voltage difference between the anode 11 and the cathode 13, the display screen of the display panel has a bala...
