In order to better understand the technical solutions provided by the embodiments of the present specification, the following detailed description of the technical solutions of the embodiments of the present specification is made through the accompanying drawings and the specific embodiments, and it should be understood that the specific features of the embodiments of the present specification are detailed descriptions of the technical solutions of the embodiments of the present specification, and not limit the technical solutions of the present specification, and the technical features of the embodiments of the present specification may be combined with each other without conflict.
In this document, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.

Therefore, when a large-size and high-resolution display is demanded, a large-size and high-resolution display is usually realized by adopting a mode of splicing a plurality of display screens. However, the large-size high-resolution display screen obtained by splicing the display screens has a splicing gap visible to naked eyes, the minimum splicing gap of the existing vehicle-mounted display screen is 5mm, and a user can intuitively feel the existence of the splicing gap in the using process, so that visual sense is influenced, and the user experience is poor.

The pixel unit 101 may be a repeating unit composed of a plurality of sub-pixels, for example, one pixel unit 101 may include an R sub-pixel, a G sub-pixel, and a B sub-pixel, which is not particularly limited.

Therefore, the array substrate provided by the embodiment of the application can replace a spliced screen in the existing vehicle-mounted field, and can realize that one display screen displays at least two different functional modules, for example, an instrument panel, a central control area, a copilot control area and the like are displayed on one display screen at the same time. And all pixel units of the array substrate provided by the embodiment of the application are arranged in an array manner, each display subarea is divided according to the driving unit, and a splicing gap for physically splicing the screens does not exist, so that the technical problem that a large-size high-resolution display screen obtained by splicing a plurality of display screens has a splicing gap visible to naked eyes and has poor display effect can be avoided, and a user can intuitively feel the existence of the splicing gap in the using process, thereby influencing visual sense and causing poor user experience.

The driving device can realize stronger driving effect, can overcome the problem of insufficient driving force of a single scanning driver, and can realize large-size high-resolution display.
In one possible embodiment, as shown in fig. 2, the scan driver 211 may be a driving chip IC or an integrated driving circuit integrated on the array substrate, and two scan drivers driving the same display sub-region 110 may take the form of the same driver. The driving chip IC is adopted as the scanning driver, so that the display stability is good and the reliability is high. The integrated driving circuit integrated on the array substrate is adopted as a circuit integration level of the scanning driver, so that the requirement on process stability is high.
In a possible implementation manner, fig. 3 is a schematic structural diagram of still another array substrate provided in an embodiment of the present application. As shown in fig. 3, the array substrate provided in the embodiment of the present application further includes at least two data lines 400, where the data lines 400 are indicated by two-dot chain lines in fig. 3, it should be noted that each column of pixel units 101 shown in fig. 3 may be electrically connected by using the data lines 400, and the data lines 400 between each column of pixel units in fig. 3 are not illustrated because of more lines; each of the driving units 210 mentioned in the above embodiment further includes one data driver 212, and the data driver 212 is electrically connected to the target pixel unit through the data line 400. The target pixel unit is the pixel unit 101 in the display sub-region 110 correspondingly driven by the driving unit 210. The scan driver 211 may supply a scan signal to the pixel unit 101 to perform scan driving, that is, to drive on or off of a Thin Film Transistor (TFT) in the pixel unit 101, and thus, the scan line 300 is electrically connected to a gate electrode of the thin film transistor. The data driver 212 may supply a data signal to the pixel unit 101, i.e., input a data signal to the TFT in the pixel unit 101, and the data line 400 is electrically connected to a source of the thin film transistor. The display signals typically include scan signals and data signals to enable a picture display. The data driver 212 may employ a driving chip IC or an integrated driving circuit integrated on the array substrate.
According to the array substrate provided by the embodiment of the application, each display subarea 110 corresponds to one data driver 212, and independent data signals can be provided for the corresponding display subarea 110, so that split-screen display is realized.
In one possible embodiment, as shown in fig. 2, each row of target pixel cells is electrically connected to two scan drivers 211 of the corresponding display sub-area 110 through one scan line 300. That is, each row of pixel cells 101 of each display sub-area 110 is driven in common by two scan drivers 211 through one scan line 300, which two scan drivers 211 belong to one driving unit 210. The two scan drivers 211 driving the same display sub-area 110 may be disposed at both sides of the display area 100 in a symmetrical arrangement, and the present application is not particularly limited. Since the pixel units 101 are arranged in an array, the scan drivers 211 are usually scanned line by line, and each row of pixel units 101 may be electrically connected to two scan drivers 211 through one scan line 300.
In the array substrate provided by the application, each row of pixel units 101 corresponding to each display subarea 110 is electrically connected with two corresponding scanning drivers through the same scanning line 300, namely, two scanning drivers 211 jointly drive one row of pixel units 101 in one display subarea 110 through the same scanning line 300, and a plurality of rows of pixel units 101 are driven through a plurality of scanning lines 300, so that the two scanning drivers 211 jointly drive one display subarea 110. The bilateral scanning driver can provide larger driving force for common driving of pixel units in the same row, and the display screen driving circuit with more pixels is longer due to larger size, and the display driving cannot be realized by only using one scanning driver without insufficient driving force.
In one possible embodiment, each row of target pixel cells may be electrically connected with two scan drivers of the corresponding display sub-region by two scan lines. In each display subarea, each row of pixel units can be divided into two parts, the number of the two parts of pixel units can be the same or different, and the pixel units of each part can be electrically connected with a corresponding scanning driver through a scanning line, so that the pixel units of each display subarea can be driven separately and independently through the two scanning drivers, the problem of overlarge driving load of each scanning driver can be avoided, a better driving effect is ensured, and finally, the split screen display effect meeting the requirements is obtained. The arrangement of the pixel units, the arrangement of the scanning lines and the arrangement of the positions of the scanning drivers in the two display sub-areas may be symmetrical or asymmetrical, and the application is not particularly limited.
In a possible implementation manner, fig. 4 is a schematic structural diagram of still another array substrate provided in an embodiment of the present application.
