摘要： In a display driver, a first backlight control unit using a histogram and a second backlight control unit using an optical sensor can be used in combination. The display driver includes a PWM generating unit setting a control signal value consisting of a product of a luminance rate of X % and a luminance rate of Y % as a luminance rate of a control signal for controlling a backlight with respect to maximum backlight luminance when a luminance rate of a control signal obtained by first backlight control with respect to the maximum backlight luminance is X % and a luminance rate of a control signal obtained by second backlight control with respect to the maximum backlight luminance is Y %.

摘要： A liquid crystal display device includes a liquid crystal display panel; and a driver driving the liquid crystal display panel. The liquid crystal display panel includes: a first substrate on which subpixels each including a pixel electrode are integrated; and a second substrate opposed to the first substrate, a plurality of common electrodes being formed on the second substrate. The display region of the liquid crystal display panel is divided into a plurality of sections respectively corresponding to the common electrodes. When a partial display in which an image is selectively displayed in a selected section is performed, the liquid crystal driver drives the common electrode corresponding to the selected section to a predetermined common voltage level, sets the common electrodes corresponding to the non-selected sections to a predetermined reference level, and sets pixel electrodes of subpixels in the non-selected sections to the reference voltage level.

摘要： A display control device and technique for controlling displays on a display unit, in which a plurality of display segments are two-dimensionally arranged (e.g. a dot matrix type display unit), is provided. The technique is effectively applicable to a write data latch circuit of a memory for storing display data in the display control device, such as, for example, a liquid crystal display control device, a mobile electronic apparatus, etc. A display drive control technique for controlling a moving picture display mode of a display device is also provided. The display drive control circuit controls a picture display mode of a display device for displaying still pictures and moving pictures to a liquid crystal display device, such as, for example, a dot matrix type display devices, an organic EL display device, etc.

摘要： A display device includes a boosting power supply circuit, a logic circuit and a charge transport path. The boosting power supply circuit generates a boosted power supply voltage by boosting an analog power supply voltage. The logic circuit is responsive to a decrease in a voltage level on at least one of power supply lines to which analog and logic power supply voltages are supplied for controlling a source line drive circuitry and a gate line drive circuitry to discharge charges accumulated in the display panel. The charge transport path is configured to transport charges from a power supply line on which the boosted power supply voltage is generated to a power supply line which supplies an internal logic power supply voltage to the logic circuit in response to the decrease in the voltage level on the at least one of the first and second power supply lines.
