These terms are only used to distinguish different main data lines from each other. For example, the first main data line may also be referred to as a second main data line, and similarly, the second main data line may also be referred to as a first main data line without departing from the scope of embodiments of the present invention.
An embodiment of the present invention provides a display panel, as shown in fig. 1, fig. 1 is a schematic structural diagram of the display panel provided in the embodiment of the present invention; the display panel 1 includes a main display 11 and an auxiliary display 12, the main display 11 is provided with a plurality of main data lines D1, the auxiliary display 12 is provided with a plurality of auxiliary data lines D2, and the main data line D1 and the auxiliary data line D2 are connected to the same driver chip IC.
When the display panel 1 is operated, the driving chip IC supplies a driving signal to the main data line D1 and the sub data line D2 to cause the pixels in the main display panel 11 and the sub display panel 12 to emit light, thereby displaying an image on the display panel 1.
This embodiment is through setting up main display screen 11 and auxiliary display screen 12 in display panel 1 to set up many main data lines D1 on main display screen 11, set up many auxiliary data lines D2 on auxiliary display screen 12, make main data line D1 and auxiliary data line D2 all be connected to same driver chip IC, so not only can increase display panel 1's area of display, make this display panel 1 realize multizone and show. That is, when the display panel 1 displays, the driving chip IC controls the main display 11 and the auxiliary display 12 to display different contents, so as to enrich the user experience; in addition, in the embodiment, the main data line D1 and the auxiliary data line D2 are both connected to the same driver IC, so that the user experience is enriched, and at the same time, an additional driver IC is not required to be added, thereby avoiding the increase of the cost of the display panel 1. For example, taking the display panel 1 as an example of a smart watch, when the smart watch has a communication function, if the smart watch receives text information, the present embodiment may cause the main display 11 to display detailed text content of a short message or a mail by causing the auxiliary display 12 to display short information similar to a reminder of the short message or the mail. Or, in this embodiment, the main display 11 may display a video including a complex dynamic image, and when the main display 11 plays the video, the auxiliary display 12 displays the name of the video being played or displays information such as the current time, so as to meet the diversified requirements of the user. In addition, in the standby state, the present embodiment can also make the auxiliary display 12 display information such as time, thereby avoiding unnecessary increase of power consumption when the main display 11 displays information such as time.
