Claim 4:
5. The gamma voltage generator according to claim 3, wherein, the switching module of each dynamic buffer comprises a first switch, a second switch, and a third switch, wherein:
the first switch has a first end connected to an output end of the buffer included in the dynamic buffer, and a second end connected to the corresponding second voltage input end node which the dynamic buffer is connected to;
a first end of the second switch and a first end of the third switch are jointly connected to a first input end of the buffer included in the dynamic buffer, a second input end of the buffer included in the dynamic buffer receives a gamma reference voltage corresponding to the dynamic buffer, a second end of the second switch is connected to an output end of the buffer included in the dynamic buffer, and a second end of the third switch is connected to the corresponding second voltage input end node which the dynamic buffer is connected to;
wherein, in the first mode, the first switch and the third switch are simultaneously turned off, and in the second mode, the first switch and the third switch are simultaneously turned on, and the second switch is turned off.
