CPC classification number: G09F9/301
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.

Abstract: An array substrate and a liquid crystal display panel are provided. By arranging scan lines on a second metal layer in the array substrate, a width of a channel of a thin-film transistor is not related to a width of a scan line, so that the width of the scan line can be increased to reduce resistance of the scan line. In addition, the impedance of the second metal layer is relatively small, so that the impedance of the scan line can be reduced. Furthermore, a channel width of the thin-film transistor is relatively small, which improves charging efficiency of the array substrate and reduces the distortion difference of scan signals.

Abstract: A display panel is disclosed. The display panel includes a photosensitive device. The photosensitive device includes a barrier component and a second active pattern. The second active pattern includes a second lightly-doped part, a second intrinsic part surrounding the second lightly-doped part, and a second heavily-doped part surrounding the second intrinsic part. In a film thickness direction, the barrier component overlaps the second intrinsic part. A dark current of the photosensitive device is reduced by the second intrinsic part, thereby improving sensitivity.

Abstract: An organic light-emitting diode (OLED) display panel and an OLED display device are provided. In a second display area of the OLED display panel, a light transmission enhancement layer is disposed on a side of a light-emitting layer away from a driving circuit layer. By disposing the light transmission enhancement layer on the light-emitting layer, a resonant microcavity of the OLED display panel can be changed by the light transmission enhancement layer. Therefore, light transmittance of the OLED display panel is increased, thereby improving an imaging effect of an under-screen camera.
