US-7495650-B2用于电光装置中抑制显示质量劣化。
专利摘要
其中锁存电路以多级连接的移位寄存器的输出信号被分支成两条路径，在相应的分支路径处设置NAND电路，并且基于输出信号接通采样开关以将图像信号采样到数据线中。然而，响应于布置在第一级输出的两条路径的左分支路径处的NAND电路和布置在最后级输出的两条路径的右分支路径处的NAND电路，既不设置采样开关也不设置数据线。由此，抑制了显示质量的劣化。
Original abstractOutput signals of a shift register in which latch circuits are connected in a plurality of stages are branched into two paths, NAND circuits are provided at the respective branched paths, and a sampling switch is turned on based on the output signals to sample an image signal into a data line. However, in response to the NAND circuit arranged at the left-branched path of the two path of a signal output by the first stage and the NAND circuit arranged at the right-branched path of the two path of a signal output by the last stage, neither the sampling switches nor the data lines are provided. With this, degradation of display quality is suppressed.
