Abstract: Provided are a low-power display driving circuit performing internal encoding and decoding and an operating method thereof. The display driving circuit includes a memory configured to store an input bit stream encoded by an encoder and a controller configured to determine a data path through which output frame data in a second frame period passes according to whether internal encoding is successful in a first frame period, wherein, when the internal encoding is successful, the controller performs internal encoding in the second frame period, stores a generated internal bit stream in the memory, allows the internal bit stream to pass through a low-power path to generate the output frame data, and when the internal encoding fails, the controller generates the output frame data by allowing the input bit stream to pass through a normal path in the second frame period, changes an encoding setting of an internal encoder, and repeats the internal encoding.

Abstract: A display driver circuit includes a receiver that receives a still image or a moving image, a frame buffer that stores the still image received by the receiver in a still image mode, an image processor that performs an image enhancement operation on the moving image transferred from the receiver or the still image transferred from the frame buffer, and a motion processor that performs a motion compensation operation using a current frame output from the image processor and a previous frame stored in the frame buffer in a moving image mode. The previous frame is data which, in the moving image mode, are processed by the image processor before the current frame and are then stored in the frame buffer. The previous frame is output from the frame buffer to the motion processor in synchronization with the current frame.

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.
