Problems solved by technology
However, since the opaque silver thin layer has a strong reflection to the external ambient light, the transmittance of the region 1 is low, which in turn causes less light to enter the optical sensor 10, resulting in a decrease in the imaging quality of the optical sensor 10

Abstract
The present invention provides a display panel and a display device, wherein the display panel includes: a display area, the display area includes a first display area and a second display area; a light emitting device located in the first display area; The light-emitting device includes a composite anode structure; in a direction perpendicular to the display panel and directed to the light-emitting surface of the light-emitting device, the composite anode structure includes a first electrode layer, a reflection adjustment layer, and a second electrode stacked in sequence layer, wherein the reflection adjustment layer includes a crystal layer; wherein the reflection adjustment layer is electrically connected to an external power supply, and under the action of an electric field on the crystal layer, the composite anode structure includes a first state and a second state , the transmittance of the composite anode structure in the first state is greater than the transmittance in the second state. Used to improve image quality.
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] The existing organic light emitting diode (OLED) technology generally adopts the microcavity effect to improve the overall light extraction efficiency of the device. Specifically, a sandwich structure of indium tin oxide / silver / indium tin oxide (ITO / Ag / ITO) is used to form a completely opaque composite anode structure, thereby enhancing the effect of the microcavity. [0003] With the development of display technology, the full screen has a large screen-to-body ratio and an ultra-narrow bezel. Compared with ordinary display screens, it can greatly improve the visual effect of the viewer, and thus has received widespread attention. At present, in a display device such as a mobile phone with a full screen, in order to realize Selfie and call functions, a front camera, an earpiece, etc. are usually arrange...
