Abstract
A method for use by a touch device to operate a touch panel includes allocating a first area of the touch panel to a touch control circuit, and performing a 2-dimensional scan on the first area. The method further includes allocating a second area of the touch panel to the touch control circuit, and applying a scan method or scan rate to the second area different from the first area.
Claims18
A method for use by a touch device to operate a touch panel, the method comprising:
- a temperature sensor detecting a temperature of the touch device;
- identifying an overheat condition based on the temperature of the touch device;
- in response to the overheat condition, allocating a first area of the touch panel to a touch control circuit;
- performing a 2-dimensional (2D) scan on the first area;
- in response to the overheat condition, allocating a second area of the touch panel to the touch control circuit, the second area being non-overlapping with the first area;
- and
- excluding the second area of the touch panel from scanning.
4 more elements
A touch device comprising:
- a temperature sensor to detect a temperature of the touch device;
- a touch panel;
- and
- a touch control device coupled to the touch panel, and configured to identify an overheat condition based on the temperature of the touch device, and, in response to the overheat condition, to allocate a first area of the touch panel and perform a 2-dimensional (2D) scan on the first area, and to allocate a second area of the touch panel and exclude the second area of the touch panel from scanning, wherein the second area is non-overlapping with the first area.
1 more element
A touch device comprising:
- a temperature sensor to detect a temperature of the touch device;
- a touch panel;
- and
- a touch control device coupled to the touch panel, and configured to identify an overheat condition based on the temperature of the touch device, and, in response to the overheat condition, to allocate a first area of the touch panel and perform a 2-dimensional (2D) scan on the first area, and to allocate a second area of the touch panel and perform a 1-dimensional (1D) scan on the second area;
- wherein the second area is non-overlapping with the first area.
2 more elements
A touch device comprising:
- a temperature sensor to detect a temperature of the touch device;
- a touch panel;
- and
- a touch control device coupled to the touch panel, and configured to identify an overheat condition based on the temperature of the touch device, and, in response to the overheat condition, to allocate a first area of the touch panel and perform a 2-dimensional (2D) scan on the first area, to allocate a second area of the touch panel and perform a 2D scan on the second area of the touch panel at a lower scan rate than a scan rate of the first area;
- wherein the second area is non-overlapping with the first area.
