    摘要： A latch circuit for outputting data for M pixels present in one line on a display panel in a time-division manner for each pixel, in order to drive each pixel from among the M pixels based on N-bit data, includes M×N 1-bit latch circuits in which N 1-bit latch circuits are arranged in the column direction Y and M 1-bit latch circuits are arranged in the row direction X, each circuit latching 1-bit data. Each 1-bit latch circuit includes a data latch unit circuit that latches data corresponding to any one bit of the N bits at different timings for each row, a line latch unit circuit that simultaneously latches data from the data latch unit circuit in each row, and an output enable element that outputs data from the line latch unit circuit based on an enable signal for selecting any one column.

    摘要： A display driver includes a driving circuit, a first switch signal output circuit that outputs a first switch signal group to one end of a switch signal line group coupled to first to N-th demultiplexers, and a second switch signal output circuit that outputs a second switch signal group to the other end of the switch signal line group. The first switch signal output circuit sets an output terminal group of the first switch signal group to a high impedance state in a transition period of a voltage level of a switch signal.
