Abstract
Disclosed is a data driving apparatus for a display device, which controls drivers to share operation data stored in a memory. The data driving apparatus can improve a routing environment of an EEPROM on an FPCB, thereby simplifying a process of transferring operation data to the drivers and reducing the time required for a reset mode.
Claims13
A data driving apparatus for a display device, comprising:
- a memory configured to store operation data, and provide the operation data through a routing line;
- a first driver coupled to the memory through the routing line, and configured to provide a first read command to the memory and receive the operation data provided in response to the first read command, in a first operation period;
- one or more second drivers configured to share the memory with the first driver through the routing line, and receive the operation data shared through the routing line in response to the first read command, in the first operation period;
- and
- a request line shared by the first driver and the one or more second drivers,
- wherein, after the first operation period, the first driver and the one or more second drivers generate a request command when a fail occurred in the received operation data in response to the first read command in the first operation period, and share the request command with the request line,
- the first driver provides a second read command to the memory in response to the request command, in a second operation period following the first operation period, and
- the driver having generated the request command, among the first driver and the one or more second drivers, receives the operation data shared through the routing line in response to the second read command in the second operation period.

- wherein, after the first operation period, the second driver provides a first request command to the first driver in a first case that a fail occurred in the operation data received in the first operation period,
- the first driver provides a second read command to the memory in response to the first request command, in a second operation period following the first operation period, and
- the second driver receives the operation data, shared through the routing line in response to the second read command, in the second operation period.
