Abstract: A display system includes a controller and an image display panel. The controller includes a signal transmitter configured to output at least a vertical synchronization signal to a plurality of image-capturing apparatuses; and a synthesizer configured to provide synthesized image signals in units of lines obtained by synthesizing, in units of lines, image signals in units of lines output from the respective image-capturing apparatuses at a timing corresponding to a horizontal synchronization signal formed in a predetermined cycle based on an output timing of the vertical synchronization signal. The image display panel is configured to display sequentially, in units of lines, the synthesized image signals in units of lines.

Abstract: According to an aspect, a display device includes a display unit in which a plurality of pixels are arranged in a matrix along two directions intersecting with each other. Each of the pixels includes three sub-pixels corresponding to three of four colors including a first color, a second color, a third color, and a fourth color. An area of one sub-pixel among the three sub-pixels is larger than the area of each of the other two sub-pixels. A sub-pixel of the fourth color is one of the other two sub-pixels. Pixels each including the sub-pixel of the fourth color are not adjacent to each other in at least one of the two directions in the display unit.

Abstract: A capacitance-type touch panel, allowing disturbance noise and touch detection time to be reduced and having a simple configuration, is provided. The capacitance-type touch panel including: a plurality of drive electrodes each having a strip shape; a drive control circuit performing control such that a drive signal for touch detection is selectively applied to the drive electrodes; a plurality of touch detection electrodes arranged to intersect with the drive electrodes in such a manner that capacitance is formed in each intersecting part, and each outputting a detection signal in synchronization with the drive signal; and a detection circuit detecting an external proximity object based on the detection signal. The drive control circuit controls application of the drive signal in such a manner that the detection signal is a polarity-alternating signal including a positive-negative asymmetrical signal component which is due to presence of the external proximity object.
