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.
