Claim Text:
1. display device comprising: a display panel comprising a plurality of pixels coupled to a plurality of gate lines and a plurality of data lines, respectively; a gate driver configured to drive the plurality of gate lines; a data driver configured to drive the plurality of data lines; and a timing controller configured to control the gate driver and the data driver and to provide the data driver with a data signal generated by compressing an image signal received from an external device, wherein the timing controller is configured to compress the image signal according to a first compression scheme and a second compression scheme to generate a first compression signal and a second compression signal, respectively, and wherein the timing controller is configured to select whichever one, from among the first compression signal and the second compression signal, that has a relatively narrower bit width as the data signal, wherein the timing controller comprises: a first de-compression circuit configured to de-compress the data signal to generate a first de-compression data signal before compression; a first compressor configured to compress the image signal according to the first compression scheme and to output the first compression signal; a second compressor configured to receive the image signal and the first de-compression data signal and to compress the image signal according to the second compression scheme and to output the second compression signal; and a compression selector configured to select whichever one, from among the first compression signal and the second compression signal, that has the relatively narrower bit width.
