The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated, whereby a feature defining "first," "second," or the like, may explicitly or implicitly include one or more of such features, and in the description of the present invention, "a plurality" means two or more, unless otherwise specifically limited.

Each gate line is connected to one row of sub-pixels P1, for example, a first gate line GL1 is connected to the first row of sub-pixels P1 from top to bottom, a second gate line GL2 is connected to the second row of sub-pixels P1 from top to bottom.
Each data line needs to be connected to one data output pin DOP of the data driving chip 100 to transmit a data signal to a corresponding sub-pixel P1, and each gate line needs to be connected to one gate output pin GOP of the gate driving chip 200 to transmit a corresponding gate driving signal. And writes the data signal to the corresponding sub-pixel P1 through the control of the gate driving signal in the progressive scanning process to realize the intended display.
However, as resolution increases, such driving schemes require a greater number of data out pins DOP and/or gate out pins GOP; in the case of exceeding the number of output pins of the chip design, it is also necessary to increase the number of chips. This not only increases the frame space of the display panel, but also increases the manufacturing cost of the display panel.
