Abstract
A display driver circuit may include a revision controller for controlling a nonvolatile memory having instructions by which control data for controlling devices controlled by the display driver circuit are changed, and a drive controller for controlling the devices based on the instructions. The revision controller determines whether to perform a read operation to the instructions based on electrical power being applied to the display driver circuit, and transfers instruction signals, which are generated based on the determination to perform the read operation, to the driving controller.
Claims20
A display driver circuit, comprising:
- an interface configured to receive image data;
- and
- a controller configured to
- read out instructions from non-volatile memory before the display driver circuit receives a command from a host, and
- control devices driven by the display driver circuit based on at least one of the instructions.
A display driver circuit, comprising:
- a controller configured to generate control signal to control devices driven by the display drive circuit;
- the controller being further configured to
- read out instructions from non-volatile memory, and
- generate the control signal to revise a physical defect in at least one of the devices, based on at least one of the instructions.
A method of operating a display driver circuit, the method comprising:
- reading out instructions from non-volatile memory before the display driver circuit receives a command from a host;
- and
- controlling devices driven by the display driver circuit based on at least one of the instructions.
