Patent ID: 8547316

Claim:
An apparatus for displaying an image represented by an externally inputted video data, comprising: a display panel including a plurality of pixels connected to cross points between a plurality of data lines disposed successively in a first direction and a plurality of gate lines disposed successively in a second direction; a panel substrate including a data line driver configured to sequentially select the data lines of the display panel and supply video data to pixels connected to the selected data lines; control means connected to the panel substrate via signal lines having N in total where N is a natural number, and configured to select M signal lines from the N signal lines in accordance with a frame rate of the video data, and transmit M-phase video data to the panel substrate via the selected M signal lines, M being a natural number satisfying M≦N; and connecting means, provided in the panel substrate, and configured to connect the data lines to the N signal lines connected to the control means via switching circuits, wherein, the data line driver (a) controls the switching circuits of the connecting means, in accordance with the frame rate of the video data to connect the M signal lines via which the video data is transmitted, to the data lines, and (b) sequentially selects the M data lines disposed successively in the first direction of the display panel to supply each piece of the video data to be transmitted through the M signal lines to each of pixels connected to the selected M data lines, M is set to 8 for N≧8, when driving the display panel at a frame rate of 120 fps, and M is set to 4 for N≧8, when the display panel is driven at a frame rate of 60 fps.
