Abstract
Disclosed is a display device including a display panel, a driving controller that transmits a data control signal, and a data driving circuit. The data driving circuit receives the data control signal and provides a data signal to the display panel based on the data control signal. The data control signal includes frame protocol data for setting an operation of the data driving circuit. The frame protocol data includes a protocol data number signal, frame configuration data, and scrambled dummy data.
Claims18
A display device comprising:
- a display panel;
- a driving controller configured to transmit a data control signal;
- and
- a data driving circuit configured to:
- receive the data control signal;
- provide a data signal to the display panel based on the data control signal;
- determine a length of frame configuration data based on a protocol data number signal comprised in frame protocol data;
- and
- ignore scrambled dummy data received after the frame configuration data,
- wherein the data control signal comprises the frame protocol data for setting an operation of the data driving circuit, and
- wherein the frame protocol data comprises the protocol data number signal, the frame configuration data, and the scrambled dummy data.
