Abstract
A display driver includes: a data input terminal for inputting data in which display data and command data is time-division multiplexed within one horizontal scan period; a command identification signal input terminal for inputting a command identification signal for identifying command data; a latch which fetches command data specified by the command identification signal; a decoder which decodes command data fetched into the latch; and a control section which outputs a control signal corresponding to a decoding result of the decoder. The display driver drives the display section based on the control signal and display data included within the input data.

A display driver for driving a display section based on display data, the display driver comprising:
- a data input terminal for inputting data in which display data and command data is time-division multiplexed within one horizontal scan period;
- a command identification signal input terminal for inputting a command identification signal for identifying command data;
- a latch which fetches command data specified by the command identification signal;
- a decoder which decodes command data fetched into the latch;
- and
- a control section which outputs a control signal corresponding to a decoding result of the decoder,
- wherein the display section is driven based on the control signal and display data included within the input data.
A display driver for driving a display section based on display data, the display driver comprising:
- a latch which fetches input data in synchronization with a rise of a latch pulse, the input data being formed by time-division multiplexing display data and command data within one horizontal scan period, the command data being formed of a plurality of words and the horizontal scan period being specified by the period of the latch pulse;
- a decoder which decodes command data positioned at a previously determined word position within the input data fetched into the latch;
- and
- a control section which outputs a control signal corresponding to a decoding result of the decoder,
- wherein the display section is driven based on the control signal and display data included within the input data.
A method of controlling a display driver for driving a display section based on display data, the method comprising:
- fetching command data specified by a command identification signal for identifying command data from input data in which display data and command data is time-division multiplexed within one horizontal scan period;
- decoding the fetched command data;
- generating a control signal corresponding to a decoding result of the command data;
- and
- driving the display section, based on the control signal and display data included within the input data.
A method of controlling a display driver for driving a display section based on display data, the method comprising:
- fetching input data in synchronization with a rise of a latch pulse, the input data being formed by time-division multiplexing display data and command data within one horizontal scan period, the command data being formed of a plurality of words and the horizontal scan period being specified by the period of the latch pulse;
- decoding command data positioned at a previously determined word position within the fetched input data;
- generating a control signal corresponding to a decoding result of the command data;
- and
- driving the display section, based on the control signal and display data included within the input data.
