Display panel, display device and display panel processing method

Abstract

The invention provides a display panel, a display device and a display panel processing method. The display panel comprises a substrate and a first electrode layer, a light-emitting layer and a secondelectrode layer, which are arranged successively on the substrate. The light-emitting layer comprises a plurality of light-emitting regions on the substrate. Each light-emitting region comprises a plurality of light-emitting units. The plurality of light-emitting units are used for emitting N kinds of different colors of light including first color light, wherein the luminous efficiency of the light-emitting unit emitting the first color light is lower than the luminous efficiency of the light-emitting units emitting the rest N-1 kinds of color light. A sub-light-emitting layer for emitting the first color light is arranged between the first electrode layer and the second electrode layer. According to the display panel, the display device and the display panel processing method, the sub-light-emitting layer can improve the area of the light-emitting region that emits the first color light, so that the current of the light-emitting unit emitting the first color light in the light-emitting layer can be shared, the service life of the light-emitting unit is improved and furthermore, the service life of the display panel is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel, a display device, and a display panel processing method. Background technique [0002] Organic Light-Emitting Diode (OLED) has excellent properties such as low power consumption, high color saturation, wide viewing angle, thin thickness, and flexibility, so it is widely used in terminal equipment and wearable equipment. and other flexible display devices. [0003] At present, an OLED display panel includes a substrate and an anode, a light-emitting layer, and a cathode stacked on the substrate in sequence. Blue glowing unit with beams of light. [0004] However, due to the limitations of technology and materials, the luminous efficiency of the blue light-emitting unit is lower than that of the red light-emitting unit and the green light-emitting unit. short.
