Embodiment Construction

[0039] The invention provides a touch detection method of a touch panel. In a preferred embodiment, the touch detection method of the present invention is applied to a photosensitive touch panel; however, in different embodiments, the touch detection method of the present invention can also be applied to capacitive touch panels, inductive Touch panels or other touch panels that can use multi-touch detection.

[0040] figure 1 A schematic diagram of the touch panel is shown. Such as figure 1 As shown, the touch panel includes a plurality of sensing units 101 . In a preferred embodiment, the sensing unit 101 is a unit area divided on the touch panel. The sensing matrix 101 is preferably arranged in a matrix to form a sensing matrix 110, and the sensing matrix 110 includes a plurality of sensing sequences 130 parallel to each other. Each sensing sequence 130 includes a plurality of sensing units 101 arranged in a straight line. Taking the 16×16 sensing matrix 110 as an exam...

Abstract

The invention provides a touch-control detection method of a touch screen, which comprises steps of firstly providing an induction matrix which includes a plurality of sensing units, then detecting sense data output by each sensing unit and defining the sensing units as touch points or non-touch points accordingly, identifying parts of the touch points as at least one touch point group, wherein amongst the same one touch point group, each touch point is at least adjacent to projected images of other touch points in column or row direction, after defining the touch point groups, namely extracting a maximum position and a minimum position respectively in column and row directions amongst the same one touch point group, and lastly determining the position of a touch center according to the maximum position and the minimum position in column and row directions. By the touch-control detection method of a touch screen, the invention can save storage space, promotes system efficacy and increases reaction speed.

Description

technical field [0001] The invention relates to a touch detection method of a touch panel. Background technique [0002] Display panels and flat display devices using display panels have gradually become the mainstream of various display devices. For example, thin TVs for home use, liquid crystal displays for personal computers and laptop computers, display screens for mobile phones and digital cameras, etc., are all products that use a large number of display panels. As product design gradually tends to be user-oriented, display panels with touch input functions have gradually become the focus of industrial development in consideration of the user's convenience in operation. [0003] In terms of touch technology, currently widely used touch sensor panel technologies include resistive, capacitive and photosensitive. For a resistive touch sensor panel, its driving principle is to use voltage drop to find the coordinates of the contact point. The touch sensor panel is divid...
