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.

摘要： A display device is provided with a display panel; first to n-th cascade-connected drivers (n being an integer of two or more); a controller transmitting compressed image data to the first driver. The i-th driver of the first to n-th drivers includes a drive circuitry driving the display panel; a first bus adapted to data transfer to the (i+1)-th driver of the first to n-th drivers; a second bus adapted to data transfer to the driver circuitry; and a decompression section receiving the compressed image data from the (i−1)-th driver of the first to n-th drivers or the controller. The decompression section of the i-th driver transfers the received compressed image data to the (i+1)-th driver through the first bus thereof, when the received compressed image data are not associated with the i-th driver. When the received compressed image data are associated with the i-th driver, the decompression section of the i-th driver decompresses the received compressed image data to generate decompressed image data and feeds the decompressed image data to the drive circuitry through the second bus. The drive circuitry drives the display panel in response to the decompressed image data.

摘要： A display device includes a display panel, an environmental sensor, a correction circuit and a driving circuit. The correction circuit is configured to generate a corrected gray-scale data on the basis of input gray-scale data. The driving circuit is configured to drive the display panel in response to the corrected gray-scale data. The correction circuit generates the corrected gray-scale data by executing a correction using a polynomial in which the input gray-scale data are used as variables. Coefficients of the polynomial are changed in response to an output signal of the environmental sensor.
