Abstract
The present embodiment relates to a method and a system for data transmission and reception of a display device and, more specifically, to a method and a system for repeatedly checking whether an error has occurred in a data driving device configuration for high-speed communication when driving the display device to prevent the image quality degradation due to the configuration error.
Claims18
A method for data transmission and reception of a data driving device in a display device, the method comprising:
- a low-speed communication operation of performing low-speed communication with a data processing device to receive configuration value data about a high-speed communication environment and error detection information regarding the configuration value data;
- a high-speed communication environment configuration operation of configuring the high-speed communication environment by using the configuration value data and of storing the error detection information;
- an image data reception operation of receiving image data from the data processing device through a high-speed communication;
- and
- a determination operation of receiving the error detection information again through the high-speed communication and comparing the error detection information received through the low-speed communication with the error detection information received through the high-speed communication to determine whether an error has occurred in the preconfigured high-speed communication environment.
A method for data transmission and reception of a data processing device in a display device, the method comprising:
- a low-speed communication operation of performing low-speed communication with a data driving device to transmit configuration value data about an environment of high-speed communication with the data driving device and error detection information of the configuration value data;
- a first transmission operation of transmitting image data to the data driving device through the high-speed communication when the data driving device completes a clock training for the high-speed communication;
- and
- a second transmission operation of transmitting the error detection information to the data driving device through the high-speed communication.
A system for data transmission and reception of a display device, the system comprising:
- a data processing device configured to transmit configuration value data about a high-speed communication environment and error detection information of the configuration value data through low-speed communication, to transmit image data through high-speed communication, and to retransmit error detection information through the high-speed communication;
- and
- a data driving device configured to receive the configuration value data and the error detection information through low-speed communication with the data processing device, to configure the high-speed communication environment by using the configuration value data, to store the error detection information, to receive the image data through high-speed communication with the data processing device, to receive the error detection information again through the high-speed communication, to compare the error detection information received through the high-speed communication with the error detection information received through the low-speed communication, and, when the error detection information received through the high-speed communication does not match the error detection information received through the low-speed communication, to determine that an error has occurred in the preconfigured high-speed communication environment.
