Abstract
Disclosed are a timing controller and driver which are improved to have a function of compensating a source signal to be provided to a display panel, and a display system including the timing controller and the driver.
Claims15
A timing controller of a display system, comprising:
- a location weight provider configured to provide a location weight set according to the position of each horizontal line, each horizontal line displaying display data corresponding to a current horizontal period;
- and
- a data converter configured to output a transmission signal as a packet, the transmission signal having the display data and control data,
- wherein the control data includes a compensation weight generated using the location weight.
1 more element
A driver of a display system, comprising:
- a recoverer configured to receive a transmission signal, and recover and output display data of a current horizontal period and control data included in the transmission signal;
- a signal processing unit configured to generate an analog signal corresponding to the display data;
- a controller configured to provide a driving control signal in response to a compensation weight included in the control data;
- and
- an output buffer configured to output a source signal corresponding to the analog signal, and be controlled by the driving control signal in power for outputting the source signal,
- wherein the compensation weight is generated using a location weight set according to the position of each horizontal line, each horizontal line displaying display data corresponding to a current horizontal period.
3 more elements
A display system comprising:
- a timing controller configured to provide a transmission signal;
- and
- a driver configured to receive the transmission signal, recover display data of a current horizontal period and control data included in the transmission signal, and output a source signal corresponding to the display data and the control data,
- the timing controller comprising:
- a location weight provider configured to provide a location weight set according to the position of each horizontal line, each horizontal line displaying display data corresponding to the current horizontal period;
- a gray weight provider configured to provide a gray weight corresponding to a gray difference between display data of a previous horizontal period and the display data of the current horizontal period;
- a compensation weight provider configured to provide a compensation weight obtained by calculating the location weight and the gray weight;
- and
- a data converter configured to output the transmission signal as a packet, the transmission signal having the display data and the control data, the control data including the compensation weight generated using the location weight,
- wherein the driver generates an analog signal corresponding to the display data and a driving control signal corresponding to the compensation weight, outputs a source signal corresponding to the analog signal through an output buffer, and controls power of the output buffer for outputting the source signal by the driving control signal.
