The present disclosure relates to the technical field of display, and particularly to an array substrate and a display panel.
With the development of flat panel display technology, 8K resolution has become a development trend of panels. Current 8K array substrates have larger sizes and higher refresh rates, so when scanning lines turn on pixels line by line, each of the scanning lines has a shorter scanning time. This shortens writing time of data signals, resulting in insufficient charging rates, which affects display effects of display panels.
Therefore, there is a need to improve the technical problem of insufficient charging rates of pixels of current display panels.
The present disclosure provides an array substrate and a display panel to solve the technical problem of insufficient charging rates of pixels of current display panels.

The substrate 11 is usually made of glass. The first metal layer is patterned to form a gate electrode 121 of the thin film transistor and the scan lines (not shown). The active layer 14 comprises a source region and a drain region formed by doping N-type impurity ions or P-type impurity ions, and a channel region between the source region and the drain region. The active layer 14 may be made of amorphous silicon, polysilicon, or metal oxide. The metal oxide may be indium gallium zinc oxide. The source/drain layer is patterned to form a source electrode 151 and a drain electrode 152 of the thin film transistor, and the data lines (not shown). The source electrode 151 and the drain electrode 152 are respectively connected to the source region and the drain region of the active layer 14. The passivation layer 16 is formed on the source/drain layer and covers structures of the source/drain layer. The pixel electrode 17 is connected to the drain electrode 152 through a via hole in the passivation layer 16. The above structures together form the sub-pixel.

Common scanning methods are one-sided scanning and two-sided scanning. Taking one-sided scanning as an example, a scan signal “Gate” is input from a left side of a scan line to turn on an entire row of sub-pixels. However, in a large-sized display panel, a scan signal “Gate” transmitted from the leftmost side to the rightmost side is farther away, resulting in resistance/capacitance delays (RC Delays), which changes rectangular waveforms. Therefore, a time to turn on the sub-pixels farther from a scan signal input terminal will be shorter than a time to turn on the sub-pixels closer to the scan signal input terminal, which makes insufficient charging rates more serious when the data signal is input to the data line. Therefore, a first area may be selected in the array substrate, a distance between the first area and each of the scan signal input terminals being greater than a threshold. The first area comprises one or more columns of the sub-pixels, and all the sub-pixels in the first area are set as the first sub-pixels. The connecting members are provided corresponding to the first sub-pixels to increase a charging rate of each of the sub-pixels in the first area.
In an embodiment, the scan signal input terminals are disposed on a left or right side of the array substrate, and the first area is located on a side of a pixel area of the array substrate away from the scan signal input terminals. The pixel area of the array substrate is an area where all the sub-pixels are set. In this case, the array substrate adopts one-sided scanning. When the scan signal input terminals are disposed on the left side of the array substrate, the first area is located on a right side of the pixel area, and the distance between the first area and each of the scan signal input terminals is greater than a threshold. When the scan signal input terminals are disposed on the right side of the array substrate, the first area is located on a left side of the pixel area, and a distance between the first area and each of the scan signal input terminals is greater than a threshold.
In an embodiment, the scan signal input terminals are disposed on the left and right sides of the array substrate, and the first area is located in a middle of the pixel area of the array substrate. In this case, the array substrate adopts two-sided scanning. The first area is located in a middle of the pixel area, and a distance between the first area and each of the scan signal input terminals disposed on the left and right sides is greater than a threshold.
In an embodiment, the first area has a same size as the pixel area of the array substrate. That is, all the sub-pixels in the array substrate are the first sub-pixels. In this case, an effect of improving insufficient charging rate is the best.
In an embodiment, in the first area, the connecting members corresponding to the first sub-pixels are disposed in a same manner. That is, in the first area, the connecting members corresponding to the first sub-pixels have a same number, are located on same layers, and are connected in a same manner. In this case, a manufacturing process is relatively simple.
It can be understood from the above embodiments that in the present invention, a data line corresponding to at least one sub-pixel in an array substrate is connected to both ends of a connection member, so that the data line is connected in parallel with the connection member. Therefore, when a power supply voltage input of the data line is unchanged, a resistance of the data line decreases, thereby improving a charging rate of the sub-pixel.
The present disclosure further provides a liquid crystal display panel comprising an array substrate and a color film substrate disposed oppositely. The array substrate is the array substrate described in any of the above embodiments. The liquid crystal display panel of the present disclosure may be an 8K display panel with a resolution of 7680*4320, and may be applied to products such as mobile phones, computers, electronic watches, and flat panels. In the liquid crystal display panel of the present disclosure, a data line corresponding to at least one sub-pixel in an array substrate is connected to both ends of a connection member, so that the data line is connected in parallel with the connection member. Therefore, when a power supply voltage input of the data line is unchanged, a resistance of the data line decreases, thereby improving a charging rate of the sub-pixel, and making a display effect of the liquid crystal display panel better.
