When a detection device (20) detects a TP operation (touch panel operation) with respect to an electronic apparatus (100), a display device (1) advances (accelerates) timing of a scanning period which is after and nearest to detection of the TP operation so that the timing of the scanning period comes earlier than conventional timing (a) which is predetermined for a case where the TP operation is not detected in the non-scanning period, that is, the timing of the scanning period is set to timing (b).

摘要:
Electronic apparatus (100) includes a display device (1), a detecting device (20) which detects an input, a state change detecting section (31), and a control section. The control section controls the detecting device (20) so that the detecting device (20) carries out the detection more times during a non-scanning period in a case where a state change causing an improvement in detection accuracy is detected and so that the detecting device (20) carries out the detection fewer times during the non-scanning period in a case where the state change causing a deterioration in detection accuracy is detected. With the configuration, it is possible to improve detection accuracy of the detecting device while reducing electric power consumption.

摘要:
A display device includes a signal line drive circuit provided with an analog amplifier through which a stationary electric current flows. The display device further includes a control signal output section which suspends operation of the analog amplifier during a period (non-scanning period) from an start time after application to a data signal line S(i) of a voltage necessary for display is completed in a horizontal period to an end time in the horizontal period. The control signal output section sustains an AMP_Enable signal through which the analog amplifier is controlled at an L value (a low value) in the non-scanning period. As a result, stationary electric current flowing through the analog amplifier is cut off in the non-scanning period. According to this, the display device allows for reduction of electric power consumption while being capable of displaying a moving image without causing flickering.
摘要:
A display device; a method for driving the display device; and electronic equipment, each enabling a detection device to perform detection with a frequency higher than a refresh frequency of the display device and with improved accuracy are provided. The display device has a screen including pixels and repeatedly alternates between a scanning frame during which the pixels are scanned to be sequentially brought into a selected state and a pause frame during which the pixels are not scanned, and includes a detection instructing circuit configured to output detection operation control signals corresponding to touch panel detection periods to the detection device in at least one pause frame. The detection instruction signal instructs the detection device to detect at least one of detection targets which are input by touching or approaching the screen and a radio wave coming from outside the display device.
