摘要： To provide a small driver IC, in a pass transistor logic circuit that converts k-bit digital signals into analog signals, transistors supplied with a first-bit signal are arranged in a line in the channel width direction. The channel width of transistors supplied with second to k th-bit signals is made larger than (e.g., preferably larger than two times and smaller than eight times) that of the transistors supplied with the first-bit signal. The transistors are preferably arranged such that transistors of the same conductivity type are located adjacent to each other wherever possible.

摘要： A display device which achieves both a high-accuracy sensing operation and smooth input in a touch sensor unit is provided. The display device includes a display unit and the touch sensor unit. The touch sensor unit performs a touch sensing operation when the display unit does not perform a display image rewriting operation; thus, a highly accurate sensing operation is possible. A gate driver of the display unit includes a first circuit and a second circuit. The second circuit includes a plurality of shift registers. Only a display image of a region that needs to be rewritten can be rewritten. The first circuit is a shift register and designates a shift register from the plurality of shift registers included in the second circuit to operate. In the case where an image in the entire display region does not need to be rewritten, the time assigned for the sensing operation of the touch sensor unit increases, leading to the smooth input.

摘要： To achieve versatility, a driver IC has a function of generating an analog data signal from an image signal input from the outside; a function of outputting the analog data signal from an output pin; and a function of setting the analog data signal as a data signal for alternating-current driving or for direct-current driving, in accordance with data of a digital signal input from the outside. For example, the driver IC can output data signals for alternating-current driving from output pins in odd-numbered columns and data signals for direct-current driving from output pins in even-numbered columns. Furthermore, the driver IC can output data signals for alternating-current driving or for direct-current driving from all the output pins. The driver IC can drive a liquid crystal panel, a self-luminous panel, and a hybrid display panel where one subpixel includes a liquid crystal element and a light-emitting element.
