Abstract
An apparatus and method for controlling the touch sensitivity of a touch screen panel are provided. The apparatus for controlling the touch sensitivity of a touch screen panel includes a register storing a threshold value that determines the touch sensitivity of the touch screen panel, and a touch sensitivity controller changing the threshold value stored in the register on the basis of touch sensitivity control information input under the control of a user.
Claims23
An apparatus for controlling the touch sensitivity of a touch screen panel, comprising:
- a register configured to store a threshold value that determines the touch sensitivity of the touch screen panel;
- and
- a touch sensitivity controller configured to change the threshold value stored in the register on the basis of touch sensitivity control information input under the control of a user.
A touch screen display comprising:
- a touch screen panel having a plurality of touch sensors;
- a display driver circuit configured to convert sensor signals generated according to positions sensed by the touch sensors into digital data associated with touch screen positions;
- an application processor configured to generate touch sensitivity control information of the touch screen panel in response to control inputs from a user;
- and
- a controller configured to:
- change the threshold value on the basis of the touch sensitivity control information transmitted from the application processor,
- determine sensor data values from the digital data for each of a plurality of sets of frames corresponding to the touch screen positions, and
- determine differences between the digital data values corresponding to neighboring frames of the touch screen and compare the differences to the threshold value to determine the existence of a touch event and a touch position in the touch screen panel.
A method of controlling the touch sensitivity of a touch screen panel having a plurality of touch sensors, the method comprising:
- determining whether a touch sensitivity control event for controlling the touch sensitivity of the touch screen panel is generated;
- and
- when the touch sensitivity control event is generated, changing the touch sensitivity on the basis of touch sensitivity control information transmitted from an application processor in response to an input under the control of a user.
A computer program product comprising program code stored in a computer readable recording medium and configured for execution by one or more processors to perform a method of controlling the touch sensitivity of a touch screen panel having a plurality of touch sensors, the method comprising:
- determining whether a touch sensitivity control event for controlling the touch sensitivity of the touch sensors is generated;
- and
- changing the touch sensitivity on the basis of touch sensitivity control information transmitted from an application processor under the control of a user when the touch sensitivity control event is generated.
