Abstract
A touch-sensing method with unexpected-touch exclusion includes detecting sensing area to obtain touch point; checking total number of detected points forming the touch point with first and second numbers; determining a touch of the touch point as normal touch when the total number is less than or equal to the first number; determining the touch of the touch point as invalid touch when the total number is greater than or equal to the second number; checking if the touch point belongs to an edge region or not when the total number is greater than the first number and less than the second number; determining the touch of the touch point as the invalid touch when the touch point does not belong to the edge region; and determining the touch of the touch point as an unknown touch when the touch point belongs to the edge region.
