Signal transmission method and device in display device and electronic equipment

Abstract

The embodiment of the invention discloses a signal transmission method and device in a display device and electronic equipment, and the method comprises the steps: obtaining the period of a data effective signal when a main time sequence controller receives initial synchronization data, wherein the initial synchronization data comprises the data effective signal and a clock signal; when the periodof the data effective signal is not equal to a preset period, adjusting the period of the data effective signal to obtain an adjustment signal, wherein the period of the adjustment signal is equal tothe preset period; enabling the master time schedule controller to send adjustment synchronization data to the master time schedule controller and each slave time schedule controller, wherein the adjustment synchronization data comprises the adjustment signal and the clock signal; and enabling the master time sequence controller and the slave time sequence controllers to transmit video signals according to the adjustment synchronization data respectively. According to the signal transmission method and device in the display device and the electronic equipment, the charging uniformity can be improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a signal transmission method and device in a display device and electronic equipment. Background technique [0002] Currently, a high-resolution display panel requires multiple timing controllers to be driven, and the multiple timing controllers include a master timing controller and multiple slave timing controllers. Each slave timing controller is connected to the master timing controller. [0003] The master timing controller is used to transmit synchronous data to the slave timing controller. The synchronous data includes data valid signal and clock signal; There are differences between them, and there are differences between the data valid signals of each slave timing controller and the master timing controller and between the data valid signals of the slave timing controllers, resulting in a large phase difference between the timing controllers, resulting in the...
