Gamma buffer control method, device and equipment

The invention provides a method, a device and equipment for controlling gamma buffers. Switching of input voltage of a positive input end and input voltage of a negative input end is executed at a first preset time interval by controlling the gamma buffers in a multi-stage driver. Therefore, the superposition of the offsets of the gamma buffers in the multi-stage driver is avoided, the fluctuation value of the generated gamma voltage offset is reduced, and the noise in the display panel is avoided. 本公开提出一种伽码缓冲器的控制方法、装置及设备，通过控制多级驱动器中的各伽码缓冲器之间以第一预设的时间间隔执行正输入端与负输入端的输入电压的切换。从而避免了多级驱动器中伽码缓冲器的偏移量的叠加，减小了产生的伽码电压偏移量的波动值，避免了显示面板中出现噪声。
