Title:
CONTROL METHOD AND APPARATUS FOR SOURCE DRIVER, AND DISPLAY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/082364
Kind Code:
A1
Abstract:
Provided in the present disclosure are a control method and apparatus for a source driver, and a display system. The control method comprises: when a source driver is in a charging state, acquiring a plurality of first voltages and a plurality of second voltages, and calculating a plurality of third voltages; according to each first voltage, each corresponding second voltage and each corresponding third voltage, determining whether a first power-saving amount is greater than a first predetermined threshold value and/or whether a second power-saving amount is greater than a second predetermined threshold value when data of the next rows is sent to data channels after each switch device is switched on; and when the first power-saving amount is greater than the first predetermined threshold value and/or the second power-saving amount is greater than the second predetermined threshold value, controlling each switch device of a target source driver to switch on, and then sending the data of the next row to the corresponding data channels, wherein the target source driver is a source driver that has a first power-saving amount that is greater than the first predetermined threshold value, or all the source drivers are target source drivers. By means of the present disclosure, the problem of the power consumption of a source driver being relatively high is solved.
