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:
- after 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 touched 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 a point of time and setting the calculated touch position as a center position of increase/reduction in an image;
determining whether a touch pressure applied in the touch position is increased or reduced after the point of time; and
when the touch pressure is increased or reduced, zooming in or out an image by increase or reduction in the intensity of the sensing signal corresponding to the touch pressure.

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.
