Abstract
A scanning line driving circuit includes an arithmetic circuit for generating an operation result for specifying a unit register for outputting an output signal by means of an arithmetic process on an output number control signal for specifying the number of signals to be outputted. An input stage of each unit register is provided with a signal control circuit for controlling whether to allow the unit register to output an output signal based on the operation result.
Claims8
A display panel driving circuit, comprising:
- a plurality of unit driving circuits for outputting signals to a plurality of scanning lines or a plurality of image signal lines of a display panel;
- and
- an arithmetic circuit for receiving a first control signal for specifying the number of signals to be outputted, and generating a second control signal for specifying a unit driving circuit which outputs a signal, out of said plurality of unit driving circuits according to an arithmetic process on the first control signal, wherein
- each of said plurality of unit driving circuits includes a signal control circuit for controlling whether to allow the unit driving circuit to output a signal based on said second control signal.
