Abstract
Disclosed is a display apparatus including two scanning circuits of the same configuration and layout, arranged on either sides of the display part. As long as one of the scanning circuits is in operation, the other scanning circuit is in a state in which no output signal is output.
Claims24
A semiconductor circuit comprising:
- a first scanning circuit;
- and
- a second scanning circuit;
- each of the first and second scanning circuits including
- a plurality of unit registers,
- wherein an output of each of the unit registers of the first scanning circuit and an output of each of the unit registers of the second scanning circuit, corresponding to each other, are coupled to each other;
- and
- each of the unit registers of the first and second scanning circuits includes
- a circuit element that, responsive to a control signal supplied thereto, switches an output state of said each of the unit registers of the first and second scanning circuits between a state in which an output signal is output and a state in which no output signal is output.

A method for driving a display apparatus including a first scanning circuit and a second scanning circuit arranged facing each other with a display section in-between for delivering a scanning signal from one line to another;
- the display part including an array of a plurality of pixels;
- the method comprising:
- setting the second scanning circuit in a state in which no output signal is output during when the first scanning circuit is outputting an output signal;
- and
- setting the first scanning circuit in a state in which no output signal is output during when the second scanning circuit is outputting an output signal for a scan operation, a scanning direction of the second scanning circuit being opposite to a scanning direction of the first scanning circuit to perform bidirectional scanning.
