RESISTIVE TOUCH PANEL AND METHOD FOR DETECTING TOUCH POINT TYPE
First Claim
1. A method for detecting a touch point type in a resistive touch panel, wherein the resistive touch panel has multiple detecting areas, the method comprising the steps of:
- obtaining multiple touch points when a touch operation is generated on a touch panel;
determining whether the touch points are capable of being combined to be a combined touch point when the touch points are located in adjacent detecting areas; and
determining whether the combined touch point is a first-type touch point or a second-type touch point when the touch points are capable of being combined to be a combined touch point.

Abstract
A resistive touch panel and a method for detecting the touch point type are disclosed. The resistive touch panel has multiple detecting areas. The method includes the following steps: obtaining the positions of multiple touch points when a touch operation is generated on the touch panel; determining whether the touch points can be combined to be a combined touch point when the touch points are located at adjacent areas; and determining whether the combined touch point is a first-type touch point or a second-type touch point when the touch points can be combined to be the combined touch point.

9. A resistive touch panel comprising:
-
a first-direction first electrode group including m electrodes; a first-direction second electrode group including m electrodes; a second-direction first electrode group including n electrodes; a second-direction second electrode group including n electrodes; wherein the 2m+2n electrodes divide the resistive touch panel into m×
n detecting areas;a multiplex switching circuit connected to each of the 2m+2n electrodes; and a control circuit connected to the multiplex switching circuit, wherein the control circuit determines whether the touch points are capable of being combined to be a combined touch point when a touch operation is generated, and determines whether the combined touch point is a first-type touch point or a second-type touch point when the touch points are determined to be capable of being combined to be a combined touch point. - View Dependent Claims (10, 11)
