摘要： A display device is provided with a display panel on which a plurality of display pixels are provided; a backlight illuminating the display panel; and a display panel driver driving the display panel. The display panel driver externally receiving image data and a clock signal for controlling timings of receiving the image data. The display panel driver includes a backlight controller generating a PWM-modulated drive signal to drive the backlight. The frequency of the PWM-modulated drive signal is dependent on a frequency-divided clock signal generated by frequency dividing of the clock signal externally received. The frequency-divided clock signal is generated so that the frequency of the PWM-modulated drive signal is kept constant when the frequency of the clock signal externally received is switched.

摘要： A display apparatus includes: a display device; a display device driver which drives the display device; a compression section adapted to an operation of generating compression data by compression processing performed on image data; and a transmission section which, when receiving compressed data from the compression section, transmits the compressed data to the display device driver by using a serial data signal. The compression section performs the compression processing with a data compression ratio selected in response to a frame rate with which the display device driver drives the display device. The display device driver receives the serial data signal from the transmission section, generates decompressed data by decompressing the compressed data transmitted by the serial data signal, and drives the display device in response to the decompressed data. The data compression ratio used in the compression processing is set so that the transmission rate of the serial data signal from the transmission section to the display device driver is kept constant independently of the frame rate.

摘要： A display data correction apparatus is provided with: a control circuit responsive to an input gray-level value for initially providing first to N-th control points (N≧3) defined in a coordinate system in which a first coordinate axis is associated with the input gray-level value and a second coordinate axis is associated with an output gray-level value to be calculated for the input gray-level value; and a processing circuit obtaining an output gray-level value by repeating an update operation in which the first to N-th control points are updated. The degree (N−1) Bezier curve is used as an approximated curve of the gamma curve. The output gray-level value is finally obtained as the coordinate value of a specific point in the degree (N−1) Bezier curve along the second coordinate axis, where the specific point has the coordinate value closest to the input gray-level value along the first coordinate axis.
