Abstract: A data processing apparatus which revises n-bit image data, includes a frame memory which stores therein n?m bit image data of a previous frame; a memory interface which outputs n-bit revision data including upper n?m bits having n?m bit image data of the previous frame outputted by the frame memory and lower m bits having fixed data corresponding to a decimal value 1; a first reviser which revises a color temperature of current frame image data by using n-bit image data of a current frame and the revision data; and a second reviser which revises a gray scale of the current frame image data by using the image data outputted by the first reviser and the revision data.

Abstract: A data processing apparatus includes a first memory which comprises a first input/output port and a second input/output port; a second memory which is connected to the first memory and comprises a third input/output port; and a controller for controlling the first and second memories to perform operations of: (a) writing data to the first memory through the first input/output port; (b) reading the data from the first memory through the second input/output port; (c) writing the data read out of the first memory to the second memory through the third input/output port; and (d) reading the data from the second memory through the third input/output port; wherein the operation (a) is performed at a first frequency and the operations (b), (c), (d) are each performed at a second frequency, wherein either: (i) the first frequency is different from the second frequency, or (ii) the first frequency is equal to the second frequency but in each of the operations (b), (c) and (d) the data is different in phase than in the

Abstract: A display device displays an image with high display quality even if a temperature is changed, and includes a driving apparatus. Resistors having the same resistance value are used in a resistor string of a gray voltage generator, and a signal controller converts a number of bits of an input image signal into a signal having an increased number of bits. As a result, dynamic capacitance compensation processing and gamma curve modification can be separated from each other and performed independently when an ambient temperature of the display device is changed.
