According to one embodiment, a display device includes a display panel configured to perform display operation based on a pixel signal in a display period, a detector configured to perform touch detection operation in touch detection periods, and a driver configured to control frame operations. The driver is configured to control a first frame operation in a first frame periods including the display period, a first touch detection period and a first display adjustment period, and control a second frame operation in a second frame periods including the display period, a first touch detection period and a second display adjustment period. The second display adjustment period is longer than the first display adjustment period and includes the second touch detection period.

Bump areas for signals are spread on upper and lower positions with respect to Vdd and Vss lines in an I/O buffer. Thus, the direction of routing the lines from bumps for signals to the I/O buffers is spread in two directions. A greater number of I/O buffers can be accommodated without increasing the size of a semiconductor integrated circuit.

Semiconductor integrated circuit

An integrated circuit has a functional circuit for achieving an actual operation function of the integrated circuit, and a redundant circuit for replacing a defective circuit within the functional circuit. This integrated circuit has I/O regions for signal transmission between the functional circuit and outside of the functional circuit. Each I/O region incorporates fuse boxes for switching from a defective circuit to the redundant circuit.

Integrated circuit and method of designing integrated circuit

A control circuit for controlling a driving circuit that provides signals to a displaying means, wherein a function of outputting a plurality of digital signals at different phases is included, and said phases can be set by selective elements.
