A display panel and a manufacturing method thereof of the present disclosure provide a substrate including a non-display area, a display area disposed around the non-display area, a light-converging structure disposed on the substrate of the non-display area, and a functional layer disposed on the substrate and provided with a through-hole corresponding to the non-display area, wherein the through-hole penetrates the functional layer, thereby reducing the loss of light transmitted to the camera, greatly increasing an amount of light that enters the camera, and improving the image quality of the camera.

The present invention discloses a pixel unit, a manufacturing method, and a display device. The pixel unit includes a first positive electrode layer, a first pixel definition layer disposed on the first positive electrode layer, a second positive electrode layer disposed on the first pixel definition layer, and a second pixel definition layer disposed on the second positive electrode layer such that the first positive electrode layer and the second positive electrode layer are driven individually. The present invention, by employing two anode driving voltages in the same sub-pixel, drives two parts of a light emitting material individually to improve a brightness in a central region such that the entire pixel emits light evenly.

A display panel and a method of manufacturing the display panel are provided. The display panel includes an array substrate, a pixel definition layer, and spacers. Each of spacers includes a bottom surface and a top surface. A cross-sectional area of the top surface is less than a cross-sectional area of the bottom surface. A horizontal distance from a center to a side of the spacer gradually increases from the top surface to the bottom surface. Moreover, holes of the mask plate corresponding to positions of the spacers are defined, which ensures accuracy of photolithography and display effect of the display panel.

Embodiments of the present application provide a display substrate comprising a plurality of first banks distributed in a first direction and a plurality of second banks distributed in a second direction. Two adjacent first banks define a group of sub-pixel units of the display substrate, and two adjacent second banks define one sub-pixel unit. The first bank has a height greater than a height of the second bank. Embodiments of the present application also disclose a manufacturing method of a display substrate and a display device.

The disclosure provides a display panel, a manufacturing method thereof, and a display device. A display area is defined on a surface of the display panel, and a first electricity supply area and a second electricity supply area are disposed opposite to each other at two sides of the display area. The display panel includes a substrate layer, and a first metal layer and a second metal layer which are sequentially disposed on the substrate layer, and an insulating layer is further disposed between the first metal layer and the second metal layer in the display area.

An organic light-emitting display panel, a manufacturing method thereof, and an organic light-emitting display device are provided. The organic light-emitting display panel includes a substrate, a plurality of anode electrodes, a pixel definition layer, an electron transport layer, and a cathode electrode. The pixel definition layer surrounds to form a plurality of array-distributed grooves, and the anode electrodes are disposed in the grooves one by one. The pixel definition layer includes first retaining walls, second retaining walls, and third retaining walls. At least one compartment is formed among a first organic light-emitting layer, a second organic light-emitting layer, and a third organic light-emitting layer disposed on the anode electrodes.

The present disclosure provides a display panel and a manufacturing method thereof. The display panel includes at least a part of metal layer disposed in a bonding area. The metal layer includes a first sub-metal layer, a second sub-metal layer, and a third sub-metal layer disposed in sequence and in a stack. A material used as the first sub-metal layer and the third sub-metal layer is one of molybdenum, titanium, or molybdenum-titanium alloy, and a material used as the second sub-metal layer is copper. The display panel provided by the present disclosure can solve problems that metal silver in the bonding area cannot be exposed outside and metal copper exposed outside is easily oxidized.

The present invention provides a display panel and a manufacturing method thereof, and a display device. The display panel includes an array substrate, a light emitting device layer, and a packaging layer. The packaging layer includes a plurality of first openings and spacers disposed between adjacent first openings on a spacer layer. Any one of the first openings is filled with a color resist. A plurality of metal wires are disposed in the spacers, and the plurality of metal wires constitute a plurality of first electrodes arranged in a first direction and a plurality of second electrodes arranged in a second direction.

An OLED display device including an OLED pixel driving circuit is provided. A driving thin film transistor in the OLED pixel driving circuit is configured as a double gate oxide thin film transistor, and a switch thin film transistor is configured as a top gate self-aligned oxide thin film transistor. A manufacturing method of a TFT array substrate is also provided, and the TFT array substrate is used for preparing the OLED display device.

The present disclosure provides a display panel and a manufacturing method thereof. The display panel includes a first substrate, a second substrate, a cathode layer, a plurality of spacer columns, and an encapsulation layer. The spacer columns are disposed as at least a one-circle structure surrounding an opening hole on the second substrate, and heights of the spacer columns are gradually increased from a center of the opening hole to edges thereof. The spacer columns having different heights can reflect light again, thereby improving light extraction efficiency, luminous brightness of sub-pixels adjacent to the opening hole area, and display effect.
