In one embodiment, the display panel further includes a substrate 500, and the display unit is disposed on the substrate 500.

It is understood that the substrate 500 may be a PCB circuit board, and each sub-pixel 110 is connected to an external driving circuit through a trace on the circuit board.

In one embodiment, the substrate 500 is provided with a plurality of second conductive through holes respectively corresponding to the two sub-pixels in the second direction one by one, wherein the second electrode leads of the two sub-pixels in the second direction are led out to the line connection layer of the substrate through the corresponding second conductive through holes.

It is understood that each second conductive via 101 (circle mark in the figure) respectively corresponds to each sub-pixel 110 pair in each row direction, and is connected to the second electrodes of two sub-pixels 110 in the sub-pixel 110 pair. In this way, by sharing one second conductive via 101 between two adjacent sub-pixels 110, the second electrodes of the sub-pixels 110 in the second direction are connected to each other, and the overall occupied space of the pixel is saved compared to the case that one second conductive via 101 is used for each sub-pixel 110 to connect with the driving circuit.

In one embodiment, the substrate 500 includes a plurality of first line connection layers, and the second conductive vias 101 corresponding to the sub-pixels 110 with the same color in the second direction are respectively connected to the same first line connection layer; the second conductive vias 101 corresponding to the sub-pixels 110 with different colors in the second direction are respectively connected to different first line connection layers.

It is understood that the substrate 500 may be a multilayer circuit board including a plurality of first line connection layers, a plurality of pixels in the pixel units 100, 200, 300, and 400 may include a plurality of colors, and if the pixel units 100, 200, 300, and 400 include at least three different color sub-pixels 110, such as a red sub-pixel 110, a green sub-pixel 110, and a blue sub-pixel 110, the different color sub-pixels can be obtained by combining the color sub-pixels 110. Taking fig. 1 as an example, since the four pixel units 100, 200, 300, 400 are arranged in a square matrix, and the sub-pixels 110 in each row are the same in color, the sub-pixels 110 in the first row and the fourth row are the same in color and can be connected to the same first line connection layer of the substrate 500, and similarly, the sub-pixels 110 in the second row and the fifth row, and the sub-pixels 110 in the third row and the sixth row are also connected to the same first line connection layer respectively, and the sub-pixels 110 in the first row, the second row and the third row are connected to different first line connection layers due to different colors, so that the sub-pixels 110 in different colors are connected to different line connection layers, and the same sub-pixels 110 are connected to the same line connection layer, thereby facilitating the control of pixel color.

In one embodiment, the substrate 500 is provided with a plurality of first conductive through holes respectively corresponding to the sub-pixels in the first direction one by one, and the first electrode leads of the sub-pixels in the first direction are led out to the line connection layer of the substrate through the corresponding first electrode conductive through holes.

As shown in fig. 1, the first conductive vias 102 respectively correspond to the columns of sub-pixels 110 one by one and are electrically connected to the columns of sub-pixels 110, so that the common cathode connection of the columns of sub-pixels 110 can be realized, and since one first conductive via 102 is disposed in one column of sub-pixels 110, compared with the case where one first conductive via 102 is disposed in each sub-pixel 110, the number of first conductive vias 102 is reduced, thereby reducing the overall volume of the pixel.

In one embodiment, the substrate 500 includes a second line connection layer (not shown), and each of the first conductive vias 102 is respectively conducted to the second line connection layer.

It is understood that the first electrode and the second electrode of each sub-pixel 110 may be respectively conducted to different line connection layers of the substrate 500, thereby facilitating management and maintenance. For example, it is assumed that each pixel unit 100, 200, 300, 400 includes a red sub-pixel 110, a green sub-pixel 110, and a blue sub-pixel 110, wherein the second conductive via 101 corresponding to the red sub-pixel 110 is connected to the third line connection layer of the substrate 500, the second conductive via 101 corresponding to the green sub-pixel 110 is connected to the fourth line connection layer of the substrate 500, the second conductive via 101 corresponding to the blue sub-pixel 110 is connected to the fifth line connection layer of the substrate 500, and the first conductive via 102 of each column of sub-pixels 110 is connected to the second line connection layer of the substrate 500, so that the second conductive via 102 of each column of sub-pixels 110 and the first conductive via 101 corresponding to each sub-pixel 110 are located at different line connection layers of the substrate 500.

In one embodiment, the aperture of the second conductive via 101 is 75 microns, and the second conductive via 101 is further provided with an annular ring, which is 175 microns.

It can be understood that the fabrication process of the anode conductive via 101 with the size is easy to implement, and can carry a certain voltage and current to provide power for the corresponding two sub-pixels 110.

In one embodiment, the first electrode is a cathode and the second electrode is an anode.

In one embodiment, each pixel unit 100, 200, 300, 400 includes at least a red sub-pixel 110, a green sub-pixel 110, and a blue sub-pixel 110.

It will be appreciated that the combination of the red, green and blue sub-pixels enables the pixel cell 100, 200, 300, 400 to present light of various colors. In one embodiment, the number of any one of the red, green, and blue sub-pixels 110 may include a plurality of sub-pixels 110, so as to serve as a spare sub-pixel 110 to replace the atomic pixel 110 when the atomic pixel 110 fails to light, or as a supplementary sub-pixel 110 to light simultaneously with the atomic pixel 110, thereby increasing the light intensity of the color sub-pixel 110.

In one embodiment, the walls of the anode conductive vias 101 are plated with a copper conductive layer and the holes are filled with resin ink.

It can be understood that the copper material has superior conductive performance, so that the loss of electric energy can be reduced by electroplating the copper conductive layer in the anode conductive through hole 101, and in addition, the oxidation of the copper conductive layer can be avoided due to the coating of the resin ink material on the surface of the copper conductive layer, so that the conductive performance is more stable.

In one embodiment, the number of the display units may be multiple, and each display unit is arranged in an array.

The display panel further comprises a polarizer and/or a touch layer group which are stacked on the display substrate. Specifically, the polarizer and the touch layer group are arranged on the first side of the display substrate in a laminating mode through the bonding layer. It should be noted that the lamination sequence of the polarizer and the touch layer set relative to the display substrate may be determined according to specific situations, and is not limited herein. For example, in some embodiments, a touch layer group and a polarizer may be sequentially stacked on the display substrate through an adhesive layer, but the cover plate should be located at the outermost side of the display panel.

It is understood that the polarizer and the touch layer are well known to those skilled in the art and are not important in the present application, and therefore, the detailed structure and principle thereof will not be described herein.

Based on the same utility model concept, the embodiment of the present application further provides a display device (not shown), which includes the display panel in the above embodiment.
