Abstract
A display controller comprises a buffer configured to store first pixel data input to a source line during a first period, and second pixel data input to the source line during a second period, subsequent to the first period, and a data generating unit configured to generate control data by comparing each of the first pixel data and the second pixel data with desired reference data, and transfer the second pixel data and the control data to a source driver driving the source line.
Claims19
A display controller comprising:
- a buffer configured to store first pixel data input to a source line during a first period, and second pixel data input to the source line during a second period, the second period being subsequent to the first period;
- and
- a data generating circuit configured to,
- generate control data by comparing each of the first pixel data and the second pixel data with desired reference data, the desired reference data is digital data corresponding to an intermediate voltage, the intermediate voltage being lower than a power supply voltage and higher than a ground voltage, and
- transfer the second pixel data and the control data to a source driver driving the source line.

A display driving apparatus comprising:
- a display controller configured to,
- compare each of first pixel data corresponding to a first source voltage and second pixel data corresponding to a second source voltage with reference data, and
- generate control data based on results of the comparison,
- wherein the first source voltage is input to a source line during a first period and a second source voltage is input to the source line during a second period, subsequent to the first period;
- and
- a source driver configured to input an intermediate voltage corresponding to the reference data to the source line during a portion of the second period, in response to the control data having a desired logic value.
3 more elements
A display driving apparatus comprising:
- a display controller configured to,
- store first pixel data and second pixel data, the second pixel data received after the first pixel data, and
- generate control data related to a precharge operation or a recycle operation based on the first pixel data, the second pixel data, and desired reference data, the generating the control data including,
- generating a first result based on the first pixel data and the desired reference data,
- generating a second result based on the second pixel data and the desired reference data,
- determining whether to input the desired reference data to a source line based on the first result and the second result, and
- generating the control data based on results of the determination;
- a source driver configured to receive the control data, and drive the source line based on the control data;
- and
- a display panel configured to output the second pixel data based on the source line.
