Abstract
The present disclosure relates to a display device, and more specifically, to a display device in which the noise characteristics of a transmission signal are improved by controlling image data output from a timing controller to a data driver. According to the present disclosure, it is possible to improve the noise characteristics of the transmission signal by controlling the image data output from the timing controller to the data driver.
Claims13
A display device, comprising:
- a timing controller configured to output image data and command data including a plurality of pseudo bits;
- a display panel including a plurality of pixels connected respectively to a plurality of data lines;
- and
- a data driver configured to generate a data voltage based on the image data and to apply the data voltage to at least one data line among the plurality of data lines,
- wherein the data driver includes:
- a pseudo shift register configured to generate a clock for latching the image data and the command data;
- a latch configured to maintain and output a per-frame image data on an at least one channel basis;
- a pseudo latch configured to store the pseudo bits of the image data and the command data;
- and
- an output buffer configured to output the data voltage to the at least one data line, and
- wherein the pseudo latch is configured to output a saturation signal to the timing controller when a predetermined number of pseudo bits is stored.
