Abstract

The invention discloses a display panel, a preparation method thereof and a display device. The display panel comprises a functional area, a main display area, a substrate layer, an anode layer, a pixel definition layer and a light emitting structure unit; the main display area surrounds the functional area, and the substrate layer extends from the main display area to the functional area; the anode layer is arranged on the substrate layer; the pixel definition layer is arranged on the anode layer, an opening is formed in the pixel definition layer, and the anode layer is exposed in the opening; the light-emitting structure unit is arranged in the opening; the functional area is a light-transmitting area, and a plurality of light-transmitting holes are formed in the pixel definition layerin the functional area. The pixel density of an under-screen camera area is set to be the same as the pixel density of the main display area, so that evaporation through holes with different densitiesare not formed in the metal mask any more, the process difficulty is reduced, and the cost is reduced.

Description

technical field [0001] The present application relates to the field of display panels, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] Active-matrix organic light-emitting diode (AMOLED) is a display technology. Compared with traditional liquid crystal displays used in most mobile phones, AMOLED has a wider viewing angle, higher refresh rate and higher Thin size, so it is being adopted by smartphones. In addition, the current development trend of smart phones is to develop in the direction of a full screen, that is, to provide users with mobile phones with a higher screen-to-body ratio. [0003] The mainstream full screens on the market include U-shaped notch screens and water drop-shaped full screens. This type of display is designed to further increase the screen-to-body ratio. full screen. [0004] An under-display camera display panel is also provided in the prior art, please refer to figure 1 , f...
