摘要： A recognition processing unit (22) performs recognition processing on a scan image based on a signal read from a light sensor (2) and outputs coordinate data (Co) indicating the position of an object to be detected. A mode control unit (24) determines a normal mode in which the recognition processing unit (22) is operated or a standby mode in which the operation of the recognition processing unit (22) is stopped. A thinned image memory (25) stores a thinned image when the normal mode is switched to the standby mode. The mode control unit (24) switches the standby mode to the normal mode when a newly supplied thinned image changes from the stored thinned image by a prescribed amount or more. Thus, it is possible to rapidly leave the standby mode and quickly detect the contact position.

摘要： The sub panel 100, having a plurality of gate bus lines 14, source bus lines 16, TFTs 25 and pixel electrodes, is provided with a source driver 15. The main panel 200 has a plurality of gate bus lines 24, source bus lines 16, TFTs 25 and pixel electrodes, each of the source bus lines 16 being connected to the corresponding source bus lines 16 of the first liquid crystal panel 10 through a switching TFT 17. The main panel 200, sharing the source driver 15 with the first liquid crystal panel 10, is less frequently used for display than the first liquid crystal panel 10, and is disconnected by the switching TFT 17 when only the sub panel 100 is used. This makes it possible to device a twin-panel display device low in electric power consumption.

摘要： The liquid crystal display device (1) includes a liquid crystal panel (69) having, for each of pixels (60), a digital memory element (68) for holding an electric potential according to image data and a liquid crystal cell (64) for displaying an image by receiving the electric potential from the digital memory element (68); and a liquid crystal driver circuit (10) having an AC control section (22) for reversing a polarity of an AC voltage applied to the liquid crystal cell (64) on a given cycle and an image transmission control section (21) for issuing instruction on outputting of image data to the liquid crystal panel (69). In a case where an image data transmission period contains a period during which a voltage in the liquid crystal cell (64) is reversed in response to a polarity reversal of the AC voltage applied to the liquid crystal cell (64), the image transmission control section (21) causes image data to be outputted to the liquid crystal panel (69) after the polarity reversal of the voltage in the liquid crystal cell (64) is completed. This makes it possible to (i) prevent a decrease in reliability of liquid crystal, (ii) update, without rewriting data, an image to be displayed, and (iii) prevent a deterioration in quality of a displayed image.

摘要： Provided is a portable display device sufficiently small to be held with one hand that enters a state for accepting a gesture when a fixed coordinate position near a central portion between a left display unit (14a) and a right display unit (14b) is pressed with a thumb Ftl of one hand holding the device, and accepts a command for performing such as page flipping processing based on a gesture inputted with an index finger Ffr of the other hand. Thus, it is possible to achieve an interface for input operations suitable for a two-screen display screen, where holding a two-screen portable display device naturally causes the device to enter a command accepting state to allow gesture recognition, and to enter a command non-accepting state when the portable display device is not held, in order to prevent a command from being falsely executed due to an unintended contact and such to the display screen.
