Abstract
A display device includes a timing controller configured to output driving signals and image signals in response to an external control signal, a data driver configured to receive the image signals and convert the image signals to data voltages, and a display panel including pixels configured to display an image based on the data voltages. The timing controller is further configured to detect a counted value of pulses of one selection driving signal of the driving signals, determine one selection frequency of reference frequencies, and apply the image signals to the data driver based on the selection frequency.
Claims15
A display device comprising:
- a timing controller configured to output a plurality of driving signals and a plurality of image signals in response to an external control signal;
- a data driver configured to receive the image signals and convert the image signals to a plurality of data voltages;
- and
- a display panel comprising a plurality of pixels configured to display an image in response to the data voltages, wherein the timing controller is further configured to detect a counted value obtained by counting pulses of one selection driving signal of the driving signals, determine one selection frequency of a plurality of reference frequencies in accordance with the counted value, and apply the image signals to the data driver based on the selection frequency.
A display device comprising:
- a timing controller configured to output a plurality of driving signals and a plurality of image signals in response to an external control signal;
