Claim 18:
19. The driving method according to claim 18, wherein the reading period comprises an initial voltage reading period prior to the preparation period, and a detection voltage reading period latter than the pull-up period,
wherein the method further comprises:
in the reading period, said providing, by the one second control signal line, the first level, and said reading, by the reading circuit, the detection signal of the first node comprise:
in the initial voltage reading period, providing, by the one second control signal line, the first level, and reading, by the reading circuit, an initial voltage of the first node; and
in the detection voltage reading period, providing, by the one second control signal line, the first level, and reading, by the reading circuit, a detection voltage of the first node.
