Abstract: The present disclosure discloses a display panel and a display device. The display panel includes an array substrate and a plurality of pixel units. In a first display area, a minimum distance between an edge of an anode of a second pixel unit and an edge of a corresponding light-emitting portion is greater than a minimum distance between an edge of an anode of a first pixel unit and an edge of a corresponding light-emitting portion. The display panel and the display device provided by the present disclosure prevents a problem that user experience is compromised by differences in brightness of the display panel at wide viewing angles.

Abstract: The present disclosure discloses a gate drive circuit and a display panel. The gate drive circuit includes a plurality of shift registers. Each shift register includes a level transmission signal selection module, a pull-up control module, a pulse quantity reduction module, a first inverting module, a first output module, a second output module, and a voltage boosting module. By connecting the voltage boosting module between a second electrode of a second transistor and a low potential line in series, when a first transistor is turned on, a potential of the second electrode of the second transistor can be increased, and on-state current of the second transistor can be reduced, so that a pulse amplitude of a second gate drive signal can be increased and stabilized.

Abstract: An electronic device and a display panel are provided. The display panel has a display region and a bending region positioned at one side of the display region. The display panel includes a first transparent substrate, a first inorganic layer, a second inorganic layer, and a blocking layer positioned at one side of the first transparent substrate. The second inorganic layer has a first via in the bending region of the display panel. This alleviates the mura near the bending region due to the exposure of the first transparent substrate and thus alleviates the mura issue occurred on the conventional display panel close to the bending region.

Abstract: A splicing screen includes a connecting plate and two sub-displays. The sub-display screens include gate signal lines, data lines, and first pads, each of which is electrically connected to a data line or a gate signal line. The connecting plate is arranged on one side of the sub-display screen facing away from a light-emitting side thereof. Two first pads connected to the data lines or gate signal lines of two sub-display screens that are spliced are connected in pair by the connecting plate. By utilizing pads and the connection plate to achieve a communication between the signal lines in the sub-display screens without needing, a drive circuit at an edge of each sub-display screen, a width of the non-display area at the splicing slit is reduced. The first pads are provided at one side of the sub-display screen facing the connecting plate, which reduces the width of the splicing slit.

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 BT2020 color gamut coverage and improving the color display capability of the display panel.
