Embodiment Construction

[0019]The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of this application.

[0020]Such asfigure 1 As shown, this embodiment provides a display panel, which includes a timing controller 100, a logic controller 200, and at least one source driver chip 300; the timing controller 100 generates a first enable sub-signal STP1 and a second enable The enable sub-signal STP2 is output to the two input terminals of the logic controller 200, and the logic controller 200 generates N enable signals whose phases sequentially change according to the first enable sub...

Abstract

According to the display panel and the display device, a first enable sub-signal and a second enable sub-signal which are output by a time schedule controller are modulated by a logic controller to generate a plurality of enable signals of which the phases are sequentially changed, and data signals in a source driving chip can be controlled to be output according to multi-group time division; theloading capacity of the source driving chip is reduced; the time-sharing output of the source driving chip can reduce the peak current of each output channel of the source driving chip, thereby reducing the power consumption and weakening the EMI risk.

Description

Technical field[0001]This application relates to the field of display technology, in particular to the field of data driving technology, and in particular to a display panel and a display device.Background technique[0002]In the traditional technical solution, the timing controller controls the source driver to output the data signals of all channels to the corresponding data lines at the same time through an enable signal, which causes the current of each data signal in the source driver to reach the peak value at the same time, which not only requires a higher load capacity The source driver increases the power consumption of the source driver and also increases the risk of serious EMI (Electromagnetic Interference, electromagnetic interference).Summary of the invention[0003]The present application provides a display panel and a display device, which solves the problem that a source driver chip controlled by a timing controller to output all data signals at the same time requires h...
