Abstract
Disclosed are a display device, and a source driver and a packet recognition method thereof. In the display device, when check information of a control data packet of transmitted transmission data is normal, a control data packet of to be restored is updated with a control data packet of a current cycle, and when the check information is abnormal, the control data packet to be restored is maintained, so that it is possible to normally drive a source signal even through there is an error or a change in the control data packet.
Claims20
A display device comprising:
- a timing controller configured to constitute a control data packet including check information and transmits transmission data cyclically including the control data packet;
- and
- a source driver configured to receive the transmission data, update, when the check information of a first control data packet of a current cycle is normal, a second control data packet to be restored, with the first control data packet, and maintain, when the check information of the first control data packet of the current cycle is abnormal, the second control data packet at a state of a previous cycle.
A source driver of a display device, comprising:
- a clock-data restoring block configured to receive transmission data cyclically including a clock training packet, a control data packet, and a display data packet, update, when check information included in a first control data packet of a current cycle is normal, a second control data packet with the first control data packet, maintain, when the check information of the first control data packet of the current cycle is abnormal the second control data packet at a state of a previous cycle, restore a clock signal from the clock training packet, and restore control data of the second control data packet and display data of the display data packet;
- and
- a display data processing block configured to output a source signal by using the clock signal, the control data, and the display data.
A packet recognition method of a display device, comprising:
- a step in which a timing controller configures a control data packet including check information and transmits transmission data cyclically including the control data packet;
- a step in which a source driver receives the transmission data and determines whether the check information of a first control data packet of a current cycle is normal;
- a step in which, when the check information of the first control data packet of the current cycle is normal, the source driver updates a second control data packet into the first control data packet;
- and
- a step in which, when the check information of the first control data packet of the current cycle is abnormal, the source driver maintains the second control data packet at a state of a previous cycle.
