1. A touch panel comprising:
- n first line electrodes (n is an integer of 2 or greater) to which pulses are applied;
m second line electrodes (m is an integer of 2 or greater) for use in detection, the second line electrodes being arranged to cross the first line electrodes; and
a pulse generating circuit configured to apply pulses in a selected order to n1 first line electrodes (n1 is an integer of at least 1 and not greater than n) selected from among the n first line electrodes;
a touched position on the touch panel being detected by detecting a change in capacitance between one of the first line electrodes and one of the second line electrodes.

Abstract
A touch panel includes n first line electrodes (n is an integer of 2 or greater) to which pulses are applied, m second line electrodes (m is an integer of 2 or greater) for use in detection, the second line electrodes being arranged to cross the first line electrodes, and a pulse generating circuit configured to apply pulses, in a selected order, to first line electrodes (n1 is an integer of at least 1 and not greater than n) selected from among the n first line electrodes. A touched position on the touch panel is detected by detecting a change in capacitance between one of the first line electrodes and one of the second line electrodes.

16. A method for operating a touch panel, the touch panel including n first line electrodes (n is an integer of 2 or greater) to which pulses are applied and m second line electrodes (m is an integer of 2 or greater) for use in detection, the second line electrodes being arranged to cross the first line electrodes, and configured to detect a touched position on the touch panel by detecting a change in capacitance between one of the first line electrodes and one of the second line electrodes, the method comprising the step of:
applying pulses, in a selected order, to n1 first line electrodes (n1 is an integer of at least 1 and not greater than n) selected from among the n first line electrodes.
