Display panel in which orthographic projection of lens layer on substrate is located within area delineated by outer contour of orthographic projection of cathode ring on substrate, display device and wearable device

A display panel, comprising an active area and a peripheral area, wherein the peripheral area surrounds the active area, and the display panel further comprises:

• a substrate and a plurality of light emitting devices arranged on the substrate in array, wherein the plurality of light emitting devices are located at least in the active area;
• a conducting layer comprising a cathode ring and cathodes of the plurality of light emitting devices, wherein the cathode ring is located in the peripheral area, and the cathode ring surrounds the active area;
• and
• a lens layer located at a side of the light emitting devices away from the substrate, wherein the lens layer extends from the active area to the peripheral area;
• wherein an orthographic projection of the lens layer on the substrate is located within an area delineated by an outer contour of an orthographic projection of the cathode ring on the substrate;
• wherein the orthographic projection of the lens layer on the substrate is located within an area delineated by an inner contour of the orthographic projection of the cathode ring on the substrate, and an outer contour of the orthographic projection of the lens layer on the substrate is located in the peripheral area.
