Abstract
A transmission method is provided for transmitting image data having pixels each comprising multiple sub-pixels provided for respective colors. The luminance of each sub-pixel provided for the corresponding color is represented by m-bit (m is an integer of 2 or more) luminance data R[m−1:0], G[m−1:0], and B[m−1:0]. Mapping is performed such that the bits provided for the same color at the same bit positions selected from the adjacent n (n represents an integer of 2 or more) pixels are sequentially arranged in the time direction so as to form a data unit. Data transmission is performed in units of data units (bit sets) thus mapped.
Claims11
A timing controller configured to receive image data having pixels each comprising a plurality of sub-pixels provided for respective colors, and to transmit the image data thus received to a data driver, wherein the luminance of each sub-pixel for the corresponding color is represented by m-bit (m is an integer of 2 or more) luminance data, the timing controller comprising:
- a mapping unit configured to perform mapping such that a bit set including luminance data bits of the sub-pixels provided for the same colors at the same bit positions extracted from n (n represents an integer of 2 or more) adjacent pixels are sequentially arranged in the time direction;
- and
- a transmitter configured to transmit the image data thus mapped by the mapping unit to the data driver.
A data driver configured to drive data lines of a display panel based upon image data having pixels each comprising a plurality of sub-pixels provided for respective colors, wherein the luminance of each sub-pixel for the corresponding color is represented by m-bit (m is an integer of 2 or more) luminance data, the data driver comprising:
- a receiver configured to receive, from a timing controller, image data mapped such that luminance data bits provided for the same colors at the same bit positions extracted from n (n represents an integer of 2 or more) adjacent pixels are sequentially arranged in the time direction;
- a remapping unit configured to remap the image data received from the timing controller to data arranged in units of sub-pixels;
- and
- a driving unit configured to drive the data lines based upon the data remapped by the remapping unit.
A transmission method for transmitting image data having pixels each comprising a plurality of sub-pixels provided for respective colors, wherein the luminance of each sub-pixel for the corresponding color is represented by m-bit (m is an integer of 2 or more) luminance data, the transmission method comprising mapping such that the luminance data bits of the same colors at the same bit positions selected from n (n represents an integer of 2 or more) adjacent pixels are sequentially arranged in the time direction so as to form a data unit,
- wherein data transmission is performed in units of the data units thus mapped.
