Abstract

The invention provides an array substrate and a display device. The array substrate comprises a substrate, and a thin film transistor layer, a planarization layer and a pixel defining layer which aresequentially prepared on the substrate; a camera area is arranged in a range, corresponding to a display area, of the substrate; the camera area comprises a first blind hole and a wire area at the periphery of the first blind hole; the first blind hole is used for exposing a camera arranged on the back surface of the substrate; a signal wire and a second blind hole are arranged in the wire area; and the second blind hole avoids the arrangement of the signal wire and is used for increasing the light transmittance of the wire area. Therefore, the light-tight area of the camera area is reduced, and the screen-to-body ratio is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an array substrate and a display device. Background technique [0002] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display device has thin, light, wide viewing angle, active light emission, continuously adjustable light color, low cost, fast response speed, low energy consumption, low driving voltage, and operating temperature range Wide, simple production process, high luminous efficiency and flexible display, etc., have been listed as a promising next-generation display technology. [0003] How to increase the screen-to-body ratio to achieve a full screen has become a current hot topic. The existing design generally puts the camera module under the screen, and adopts the design of opening a hole in the display area to expose the camera, thereby increasing the screen-to-body ratio. However, Since the black wiring area at the edge of the hole can...
