Touch Panel and Quick Scrolling Method Thereof
First Claim
Patent Images
1. A quick scrolling method, comprising:
- detecting a first location of an object at a fist moment of time by a touch panel;
detecting a second location of the object at a second moment of time;
calculating a moving speed of the object according to a time difference between the fist moment of time and the second moment of time and a distance between the first location and the second location; and
comparing the moving speed to a threshold value, and moving a scroll of a display window fast if the moving speed is greater than the threshold value.

Abstract
A touch panel and a quick scrolling method thereof are disclosed. The quick scrolling method includes the steps stated below. Firstly, a first location of an object at a fist moment of time is detected by a touch panel. Next, a second location of the object at a second moment of time is detected by the touch panel. Then, a moving speed of the object is calculated according to a time difference between the fist moment and the second moment of time and a distance between the first location and the second location. After that, the moving speed is compared to a threshold value, and if the moving speed is greater than the threshold value, then a scroll of a display window will be moved fast.

8. A touch panel, comprising:
-
a panel body having at least one scrolling area; a plurality of sensing elements disposed on the at least one scrolling area of the panel body for detecting a location of an object, wherein, the sensing elements detect a first location of the object at a fist moment of time and detect a second location of the object at a second moment of time; a register unit having a plurality of register areas in which the data comprising the fist moment of time, the second moment of time, the first location and the second location are temporarily storied a calculation unit for calculating a time difference between the fist moment of time and the second moment of time and a distance between the first location and the second location to further calculate a moving speed of the object; a comparison unit for comparing the moving speed to a threshold value; and a processing unit for generating a fast moving signal so as to move a scroll of a display window fast if the comparison unit determines that the moving speed is greater than the threshold value. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18)
