Abstract
A display driver includes a nonvolatile memory, an encoder, a decoder, and a compensator. The nonvolatile memory is configured to store accumulated stress data and compensation data corresponding to the accumulated stress data. The encoder is configured to encode the compensation data received from the nonvolatile memory to generate encoded compensation data. The decoder is configured to decode the encoded compensation data to generate decoded compensation data. The compensator is configured to process input image data based on the decoded compensation data and generate accumulated stress data.
Claims22
A display driver comprising:
- a first memory configured to store accumulated stress data and compensation data corresponding to the accumulated stress data;
- an encoder configured to receive the compensation data from the first memory and generate encoded compensation data;
- a decoder configured to receive the encoded compensation data and generate decoded compensation data;
- and
- a compensator configured to process input image data based on the decoded compensation data and generate accumulated stress data.
A display driver comprising:
- an encoder configured to encode accumulated stress data to generate encoded accumulated stress data;
- a first memory configured to store the encoded accumulated stress data and encoded compensation data corresponding to the encoded accumulated stress data;
- a decoder configured to decode the encoded compensation data to generate decoded compensation data;
- a compensator configured to process input image data based on the decoded compensation data and generate accumulated stress data by accumulating the input image data that is received.
A display driver comprising:
- a first memory including an accumulation memory configured to store accumulated stress data, a compensation memory configured to store compensation data corresponding to the accumulated stress data and an encoder configured to encode the compensation data of the compensation memory to generate encoded compensation data;
- a decoder configured to decode the encoded compensation data to generate decoded compensation data;
- a compensator configured to process input image data based on the decoded compensation data and generate accumulated stress data by accumulating the input image data that is received.
A display driver comprising:
- a compensator configured to process input image data;
- an encoder configured to encode accumulated stress data generated by accumulating the input image data that is received by the compensator to generate encoded accumulated stress data;
- a volatile memory configured to store the encoded accumulated stress data;
- and
- a first memory configured to store the encoded accumulated stress data received from the volatile memory and encoded compensation data corresponding to the encoded accumulated stress data,
- wherein the volatile memory is configured to receive the encoded compensation data from the first memory,
- further comprising:
- a decoder configured to decode the encoded compensation data received from the volatile memory to generate decoded compensation data.
