Abstract

The invention provides a display panel and a preparation method thereof. The display panel comprises a backplane, an inorganic layer, a flexible substrate layer, a thin film transistor layer, a lightemitting layer and a packaging layer. The backplane is provided with a first through hole. The flexible substrate layer is provided with a second through hole which is opposite to the first through hole. The thin film transistor layer is provided with a third through hole which is opposite to the second through hole. The light emitting layer is provided with a fourth through hole which is oppositeto the third through hole. The display panel has the advantages that the area of the display region is increased and the screen-to-body ratio of the display panel is increased.

Description

technical field [0001] The invention relates to the display field, in particular to a display panel and a preparation method thereof. Background technique [0002] In recent years, active-matrix organic light-emitting diodes (AMOLEDs) have received extensive attention and applications due to their advantages of high contrast, wide viewing angle, and bendability. As people's requirements for visual aesthetics are getting higher and higher, narrower display screens, full screens, and various special-shaped screens have gradually appeared in people's field of vision. [0003] The mobile phone screen with ultra-narrow bezel in the prior art has very narrow bezels around it, and the area of ​​the display area is relatively large. In the design of this type of display screen, due to the pursuit of narrowing of the bezels, there is not enough space for the upper bezel to be installed. Camera, so a through hole is designed in the display area. The through hole is usually a round ho...
