Embodiment Construction

[0039] Regarding a preferred embodiment of the method for judging an object using a touch device in the present invention, please refer to figure 1 As shown, the so-called touch device includes a touch panel, and the touch panel is mainly provided with a first sensing layer 20 on a surface of a substrate 10, and the first sensing layer 20 is mainly composed of a plurality of substrates on the aforementioned substrate. The surface of the sensor 10 is composed of sensing electrodes 21 arranged side by side along a first direction, thereby forming a one-dimensional touch interface. The so-called sensing layer 20 can be made of sensing electrodes of various shapes, such as figure 1 As shown, each sensing electrode 21 constituting the sensing layer 20 is composed of a left electrode part L01-L12 and a right electrode part R01-R12 respectively, and the left and right electrode parts L01-L12, R01-R12 are in the form of opposite triangles, They are staggered in opposite complementa...

Abstract

The present invention relates to a touch device and an object judgment method applied in the touch device, including a touch panel and a controller. The touch panel is mainly arranged on a substrate along a first direction with multiple Sensing electrodes, wherein a plurality of adjacent sensing electrodes form an object sensing area; the controller is electrically connected to each sensing electrode of the sensing layer on the touch panel to detect the sensing amount of each sensing electrode, and is sensed by the object Determine the sensing electrode with a maximum sensing amount from the sensing values ​​measured in the area, and then define a detection area adjacent to the sensing electrode with the maximum sensing amount. A first object is recognized when the change amount between the sensing quantities is less than a first limit value; the above technology is used to realize object judgment on the touch panel.

Description

technical field [0001] The invention relates to a touch device, in particular to a touch device which executes object judgment on a touch panel and has the touch panel. Background technique [0002] At present, many portable electronic devices adopt touch interface. Under the condition that the application methods and objects are more diverse and extensive, the touch interface has gradually developed from traditional single-touch and double-touch to multi-touch. It further provides the function of object recognition. Taking a smartphone as an example, after choosing to answer an incoming call, its touch interface will touch the user's ear. ) or fingers that perform other functions. [0003] The above-mentioned object judgment functions are mostly implemented on two-dimensional touch panels at present, and the projected capacitive touch panel is a kind of two-dimensional touch panel. The process forms the X-axis sensing layer, insulating layer, bridging, Y-axis sensing lay...
