Patent Images
1. An electronic device having a force touch function comprising:
- an image display module having a touch electrode;
a cover window attached to a front surface of the image display module;
a housing for receiving the image display module therein, and supporting the cover window, the housing structured such that a panel moving part exists between the housing an the image display module; and
a driving circuit for sensing a touch force based on a distance between the image display module and the housing which are spaced from each other with the panel moving part interposed in-between.

Abstract
An electronic device has a force touch function. The electronic device includes an image display module having a touch electrode. A cover window attaches to a front surface of the image display module. A housing receives the image display module therein, and supports the cover window. A panel moving part is between the housing and the image display module. A driving circuit senses a touch force based on a distance between the image display module and the housing which are spaced from each other with the panel moving part interposed in-between.

21. An electronic device for sensing a force touch, the electronic device comprising:
-
an image display module comprising a display panel to display an image in response to an image signal and a touch sensing circuit to sense a position of a touch by detecting a change in capacitance of a touch electrode in response to the touch force applied to the front surface of the image display module; a cover window attached to the front surface of the image display module; a housing comprising a housing plate covering a rear surface of the image display module and sidewalls covering lateral surfaces of the image display module and supporting the cover window, the housing supporting the image display module such that a gap exists between the housing plate and the rear surface of the image display module; a touch driver circuit to sense a change in a mutual capacitance across at least a portion of the gap between the housing plate and the rear surface of the image display module, the change in mutual capacitance caused by a change in size of the gap in response to the touch force and generate force data estimating the force touch applied to the image display module. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)
