Patent ID: 8638285

Claim:
A display device, comprising: a display panel; first to n-th cascade-connected drivers, n being an integer of two or more; and a controller transmitting compressed image data to said first driver, wherein the i-th driver out of said first to n-th drivers, wherein i is an integer, includes: a drive circuitry driving said display panel; a first bus adapted to data transfer to the (i+1)-th driver out of said first to n-th drivers; a second bus adapted to data transfer to said drive circuitry; and a decompression section receiving said compressed image data from the (i−1)-th driver out of said first to n-th drivers or said controller, wherein, when said received compressed image data are not associated with said i-th driver, said decompression section of said i-th driver transfers said compressed image data to said (i+1)-th driver by using said first bus, wherein, when said received decompressed image data are associated with said i-th driver, said decompression section of said i-th driver decompresses said compressed image data to generate decompressed image data and feeds said decompressed image data to said drive circuitry by using said second bus, wherein said drive circuitry drives said display panel in response to said decompressed image data wherein said i-th driver out of said first to (n−1)-th drivers is configured to receive a start pulse signal from the (i−1)-th driver out of said first to (n−1)-th drivers or said controller and to feed a start pulse signal to the (i+1)-th driver out of said first to n-th drivers, and wherein said i-th driver out of said first to (n−1)-th drivers is responsive to said received start pulse signal for selecting an operation from a first operation in which said decompression section transfers said compressed image data to said (i+1)-th driver by using said first bus and a second operation in which said decompression section decompresses said compressed image data to generate decompressed image data and feeds said decompressed image data to said drive circuitry by using said second bus.
