Patent ID: 8026885

Claim:
A display device comprising: a display panel having an array of a plurality of pixels; a first drive circuit for outputting a display signal corresponding to the display data to the pixels; and a second drive circuit for outputting to the pixels a select signal for selecting the pixels to receive the display signal; wherein a first display data and a first sync signal indicating the turn of each frame of the first display data are received as an input, and the second display data is displayed using a second display data obtained by converting the first display data through a data conversion circuit according to a predetermined data conversion rule and a second sync signal indicating the turn of each frame of the second display data; wherein the data conversion circuit includes n (n: an integer of 2 or more) data conversion rules and a select circuit for selecting one of the n data conversion rules; wherein the select circuit selects the n data conversion rules sequentially from the first to nth data conversion rules; wherein the data conversion rules are switched in synchronism with the first display data using the first sync signal; wherein the select circuit includes a circuit for generating an identification signal for identifying each of the n frames of the first display data to select one of the n data conversion rules; and wherein the signal generating circuit generates the identification signal using the first sync signal, the first display data and a third sync signal input separately from the first sync signal.
