METHOD AND APPARATUS FOR GENERATING DRIVING SIGNAL, BACKLIGHT AND DISPLAY APPARATUS

A method of generating a drive signal is provided. The method includes generating, by a first circuit, a first driving signal for a first image frame, the first driving signal including a plurality of first pulse width modulation signals; sending the plurality of first pulse width modulation signals to a modulation controller; detecting a vertical synchronization signal; determining whether a nearest first pulse width modulation signal is partially generated when the vertical synchronization signal is detected; and when it is determined that the nearest first pulse width modulation signal is partially generated, determining whether to delay generation of a second driving signal for a second image frame. 提供了一种生成驱动信号的方法。该方法包括通过第一电路生成用于第一图像帧的第一驱动信号，所述第一驱动信号包括多个第一脉宽调制信号；将所述多个第一脉宽调制信号发送到调制控制器；检测垂直同步信号；确定在检测到所述垂直同步信号时，是否部分生成了最近的第一脉宽调制信号；以及在确定所述最近的第一脉宽调制信号被部分生成时，确定是否延迟生成用于第二图像帧的第二驱动信号。
