Problems solved by technology

However, with this setting, the light emitted by the light-emitting device in the display panel will obliquely enter the opening area, causing light leakage and affecting the image quality.
Moreover, in the opening area corresponding to the camera module, the transmittance of the flexible substrate, the metal film layer in the thin film transistor layer, the cathode (cathode) film layer in the organic light-emitting layer, and the polarizer (POL), etc., to ambient light Both have an impact, reducing the light transmittance of the opening area, which in turn affects the imaging quality

Abstract

The invention discloses a display panel, a display device and a display panel manufacturing method. The display panel comprises at least one functional additional area, an auxiliary area arranged around the functional additional area, and a normal display area arranged around the auxiliary area. In the functional additional area, only a flexible substrate and an inorganic packaging layer in a packaging layer are arranged. A metal trace surrounding the thin film transistor layer of the functional additional area is arranged in the auxiliary area. According to the invention, the light transmittance of the functional additional area is effectively improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel capable of improving the imaging of an under-screen camera, a display device and a method for preparing the display panel. Background technique [0002] With the continuous development of display technologies, display panels with a high screen-to-body ratio have been more and more widely used. In order to obtain a larger screen-to-body ratio and realize a narrow bezel design of a mobile phone, it is generally attempted to reduce the border area. Through the pad bending technology, part of the fan-out (Fanout) wiring area of ​​the screen, the driver IC and the flexible printed circuit board (Flexible Printed Circuit, referred to as FPC) are bent to the back of the screen for bonding. Effectively reduce the length of the lower border area of ​​the screen. The upper frame area generally places camera components such as a front camera and a photosensitive device. I...
