摘要： A semiconductor device has an LCD driver formed over a silicon substrate. The LCD driver is arranged in a source output circuit region and includes two or more source output cells for generating data signals and two or more output pads for receiving the data signals and sending them to the outside. The two or more pads are arranged over the silicon substrate along a row direction, and the two or more source output cells are arranged in two rows and N columns along the row direction. A source output cell arranged at an Nth column of a first row is electrically coupled to a (2N−1)th output pad. Also, a source output cell CS1 arranged at the Nth column of a second row is electrically coupled to a (2N)th output pad. The arrangement allows for a reduced chip size.

摘要： Provided is a touch sensor panel which can increase the detection sensitivity of a touch relatively readily. The touch sensor panel controller supplies drive electrodes of a touch sensor panel with a high-voltage AC drive signal with its low level set to a negative voltage and drives them. The time of change of a drive waveform supplied to the drive electrodes of the touch sensor panel is shifted relative to the time of change of a drive waveform supplied to a display scan electrode. The touch sensor panel controller uses a charge pump in synchronization with clock signals of more than one phase to produce a high drive voltage to activate drive electrodes of the touch sensor panel, and the clock signals of more than one phase are initialized each time the drive electrode is subjected to AC pulse driving.
