Abstract: An array substrate, a manufacturing method of the array substrate, and a display panel are provided. The array substrate includes photo spacers disposed on the pixel definition sections; and a protective layer at least disposed on the photo spacers. Wherein, a material of the protective layer is an inorganic material. The protective layer has a characteristic of high hardness, which can prevent the photomask from scratching the photo spacers to generate detritus and foreign matter in an evaporation process, thereby remedying problems of poor display and decrement of service life in current display panels.

Abstract: The present application discloses a display panel and a display device. The display panel includes an active layer, a gate layer, and a metal layer, which is able to quickly pull down a falling edge of a scan signal in a first scan line when a rising edge of a scan signal in a second scan line arrives. By constructing a low-potential wiring, a control wiring, and a pull-down transistor between the first data line and the second data line, a layout with less space can be completed and an aperture ratio can be increased as much as possible.

Abstract: The present disclosure relates to a display panel and a display device. The display panel includes a substrate, a light-emitting layer, an encapsulation layer, and a light-filtering layer. The light-filtering layer is used to filter and adjust light emitted by the light-emitting layer to improve luminous purity of a red light-emitting unit and a green light-emitting unit, thereby adjusting the light emitted by the light-emitting layer of the display panel to R (0.708, 0.292), G (0.170, 0.797), and B (0.131, 0.046), thereby effectively achieving high B T2020 color gamut coverage and improving the color display capability of the display panel.

Abstract: This application provides a foldable display panel. A foldable portion in the foldable display panel includes a fixed mechanism and a rotary mechanism rotatably connected to the fixed mechanism. The rotary mechanism includes a first rotary mechanism and a second rotary mechanism. The first rotary mechanism is connected to a first flat portion. The second rotary mechanism is connected to a second flat portion. A heat dissipation member is connected to at least one of the first rotary mechanism and the second rotary mechanism. By means of this application, a risk of wear is reduced for the rotary mechanism.

Abstract: The present invention provides a display panel and a manufacturing method of the display panel. The display panel includes a first film layer, a second film layer, and a bonding layer which are arranged in a first folding region. When the display panel is in a bent state, first tangential forces of the first film layer exerted on a first surface of the bonding layer and second tangential forces of the second film layer exerted on the second surface of the bonding layer point to a center of the first folding region. The bonding layer is bent in advance, and the bonding layer is bonded with the first film layer in the bent state and bonded with the second film layer in a flat state, so bending stresses of the bonding layer are relieved.
