Method for checking object of touch control panel

Abstract

This invention relates to one trigger control board object test method, which comprises the following steps: a, determining one object first contact control board; b, judging the object moving; if not, then determining first leave ; d, sending one first hand posture signals; e, computing the first leave time; f, if it is less than one first reference time then determining second trigger on contact board; g, judging whether there is move; h, if yes, then computing object move information; I, sustaining first hand position signal to generate one second signal; j, determining the object second leave to end second hand position signal; k, computing the subject second leave time; l, if not, then determining third contact control board; m, judging whether there is move; n, if not, then determining object third leave to send one third position signal to end first hand position signal; if yes then go back to step h.

Description

Technical field [0001] The invention relates to a detection method of a touch panel, in particular to an object detection method of a touch panel. Background technique [0002] The touchpad is an input device that allows fingers to slide on a smooth panel to control the movement of the cursor. Because the thickness of the touch panel is very thin, it can be designed in ultra-thin notebook computers, keyboards, digital players or other devices, and because it is not a mechanical design, it is very easy to maintain. [0003] FIG. 1 shows a conventional two-dimensional touch panel 100, which includes a panel 102, a Y-axis sensing layer 104, an insulating layer 106, an X-axis sensing layer 108, and a bottom plate 110. When the finger 112 touches the panel 102, the sensing amount (such as capacitance or resistance) at the touched position will change, and the control circuit connected to the touch panel 100 can change the capacitance or resistance of the touch panel. Converted to sens...

Problems solved by technology

The above two methods are susceptible to the interference of external noise and lead to wrong judgments

In addition, as the volume of electronic devices continues to shrink, the touchpad 100 is also shrunk accordingly, so that when an object performs a drag gesture operation on the touchpad 100 , in addition to touching, leaving or moving the object on the touchpad 100 Waiting for the operation time is used as the judgment basis. For users who use the touchpad 100 for the first time or who are not familiar with the operation of the touchpad 100, the touchpad 100 cannot recognize the user's actions because the actions are not clear enough. If the range is too large, limited by the size of the touch panel 100, it cannot be completed at one time, and must be divided into multiple operations, causing inconvenience in operation
