Abstract: The present invention provides a display driver circuit. A determination circuit is configured to select a first mode for encoding first image data based on a first set of conditions respectively corresponding to a first set of modes. An encoder is configured to encode the first image data in the first mode. The determination circuit is additionally configured to select a second mode for encoding second image data received (n−1)th after the first image data are received; and to select a third mode for encoding third image data received (n)th after the first image data are received, based on a second set of conditions respectively corresponding to the first set of modes. A second condition in the second set of the conditions corresponding to the second mode includes a wider range of values than a first condition in the first set of the conditions corresponding to the second mode.

Abstract: A display driver circuit receives externally-encoded image data and processes the data using a memory (graphic RAM), an internal encoder, and an external decoder configured to operate on the externally-encoded image data. The processed data is provided to a display device by a source driver of the display driver circuit. Data is processed through the graphic RAM and an internal decoder or the external decoder depending on whether a slice of the data is a currently received update slice, a recently received standby slice, or a still slice.

Abstract: The present invention provides a display driver circuit. A determination circuit is configured to select a first mode for encoding first image data based on a first set of conditions respectively corresponding to a first set of modes. An encoder is configured to encode the first image data in the first mode. The determination circuit is additionally configured to select a second mode for encoding second image data received (n−1)th after the first image data are received; and to select a third mode for encoding third image data received(n)th after the first image data are received, based on a second set of conditions respectively corresponding to the first set of modes. A second condition in the second set of the conditions corresponding to the second mode includes a wider range of values than a first condition in the first set of the conditions corresponding to the second mode.
