Method of controlling user input using pressure sensor unit for flexible display device
First Claim
1. A method of controlling a user input using a pressure sensor unit which includes a plurality of first electrodes arranged on one surface of a first substrate in a first direction and a plurality of second electrodes positioned on the first electrodes and arranged in a second direction for a flexible display device, the method comprising steps of:
- at a second point of time after a lapse of uniform time from a first point of time at which a specific region of a top surface of the first substrate is touched, determining whether intensity of a sensing signal generated by a change in a distance between the first electrodes and the second electrodes corresponding to the specific region is no less than a threshold value;
when it is determined that the intensity of the sensing signal is no less than the threshold value, calculating a touch position at the second point of time and setting the touch position as a center position of increase/reduction in an image;
determining whether the intensity of the sensing signal corresponding to the touch position is increased or reduced after the second point of time;
when the intensity of the sensing signal is increased, zooming in the image corresponding to increase in the intensity of the sensing signal; and
when the intensity of the sensing signal is reduced, zooming out the image corresponding to reduction in the intensity of the sensing signal.

Abstract
There is provided a method of controlling a user input using a pressure sensor unit for a flexible display device in which the pressure sensor unit for sensing a touch position through pressure transmitted when a touch is made is formed on one surface of a substrate, by which a user may zoom in/out a displayed image by only one hand using the intensity and pattern of input touch pressure.
