Abstract
The present disclosure relates to a technology for a low power operation of a display device. The present disclosure allows reducing power consumption by supplying image data of a pixel of a preceding line again for a pixel of a current line without transmitting new image data when image data are repeated in units of pixels.
Claims15
A timing controller comprising:
- a controlling unit configured to compare first image data of a pixel of a current line with second image data of a pixel of a preceding line, to determine whether to include the first image data in a data packet based on a result of the comparison, and to insert a comparative indicator indicating the result of the comparison into the data packet;
- and
- a transmitting unit configured to transmit the data packet to a source driver,
- wherein the transmitting unit does not transmit the first image data to the source driver when the first image data is identical to the second image data, and
- wherein the comparative indicator indicates whether to include the first image data in the data packet or whether to transmit the first image data.
2 more elements
A display device comprising:
- a source driver configured to receive image data and output a data voltage corresponding to the image data to a pixel from pixels;
- and
- a timing controller configured to transmit the image data to the source driver,
- wherein the timing controller compares first image data of a pixel of a current line with second image data of a pixel of a preceding line, determines whether to include the first image data in a data packet based on a result of the comparison, and insert a comparative indicator indicating the result of the comparison into the data packet, and,
- wherein the timing controller does not transmit the first image data to the source driver when the first image data is identical to the second image data, and
- wherein the comparative indicator indicates whether to include the first image data in the data packet or whether to transmit the first image data.
