Claim 1:
2. The gamma voltage generator according to claim 1, wherein,
each dynamic buffer comprises a buffer, a switching module and a voltage difference detecting module,
the voltage difference detecting module of each dynamic buffer has a first detecting end connected with a first input end of the buffer included in the dynamic buffer, a second detecting end connected with the corresponding second voltage input end node which the dynamic buffer is connected to, and an output end for outputting a switch control signal; and
the switching module of each dynamic buffer is configured to allow in the second mode or forbid in the first mode, the buffer included in the dynamic buffer to output a buffer voltage to the corresponding second voltage input end node which the dynamic buffer is connected to, based on the switch control signal of the voltage difference detecting module included in the dynamic buffer or other voltage difference detecting module.
