摘要： The present invention is so arranged as to include (a) gradation reference potential generating means including a group of output terminals whose voltages are determined in accordance with a voltage division ratio of one ladder resistor, so as to output gradation reference potentials, for example, of 1024, which is a 16 multiple of a required 64-gradations; (b) output terminal designating means including a memory for designating, among from the output terminals, an output terminal for each of the 64-gradations required, in accordance with the display modes; and (c) selecting means for selecting an output terminal that corresponds to an input gradation signal, among from the output terminals designated by the output terminal designating section, and for applying a voltage via the thus selected output terminal to a display screen. With this arrangement, it is possible to attain very similar gradient signal-brightness characteristics for respective display modes with high accuracy, in order to prevent a gradient display from being changed due to switchover of the display modes.

An object of the present invention is to, when gradation conversion is performed in the display device using an error diffusion method, provide a display with a smooth gradation change even at boundaries of display blocks. In an error diffusion operation circuit (36) of a source driver unit (302), an error diffusion process is performed for each pixel based on, in addition to image data (Da) for a display block of the source driver unit (302), image data (Da) for areas near boundaries between the display block of the source driver unit (302) and display blocks of source driver units (301, 303) in previous and subsequent stages. A video signal is generated based on error-diffused image data (Db) generated by the error diffusion process.

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： 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.
