Problems solved by technology

[0003] Fingers cannot click or input more accurately when operating a touch-screen mobile phone. At present, most touch-screen mobile phones cannot recognize whether the touch object is a finger or a pen tip. The processing is the same when receiving a click or input action, so it will lead to misuse

Embodiment Construction

[0020] refer to figure 1 Shown is a schematic structural view of the electronic device of the present invention. The electronic device 1 includes a touch panel 14 , an A / D (Analog to Digital, Analog to Digital) converter 15 and a processor 16 .

[0021] In this preferred embodiment, the touch panel 14 (such as image 3 (shown) is a resistive touch panel, which mainly includes four-wire, five-wire and eight-wire touch panels. Since the cost of the four-wire touch panel is relatively low and the technology is relatively mature, it has become the most common specification at present.

[0022] For the convenience of description, in this embodiment, a four-wire electronic touch panel is taken as an example. The touch panel 14 has transparent insulating points between the upper and lower layers coated with ITO (indium tin oxide). Let the upper and lower layers of ITO maintain a certain air layer and let it handle the non-conductive state. When the fingertip, pen tip or other obj...

Abstract

The invention relates to a method for recognizing a touch control object by an electronic device. The electronic device is provided with a touch control panel and an analog-to-digital converter. The method comprises the following steps of: setting a critical value of a resistance value in the Z-axis direction of the touch control panel, wherein the critical value is used for distinguishing the type of the touch control object; pressing the touch control panel of the electronic device by the touch control object; obtaining the current resistance value in the Z-axis direction of the touch control panel; and comparing the current obtained resistance value in the Z-axis direction with the set critical value for recognizing the type of the current touch control object. The invention also provides an electronic device. The input accuracy can be greatly improved by utilizing the invention.

Description

technical field [0001] The invention relates to an electronic device and a method for identifying a touch object thereof. Background technique [0002] With the development of society and the advancement of science and technology, touch screen mobile phones with more humanized interface and easier input are becoming more and more popular. Touch-screen mobile phones now account for an increasing market share. This type of mobile phone has a common feature, that is, the screen is large, because the space occupied by the keyboard is omitted, so the screen occupies most of the area. Current smart phones, especially high-end and luxury mobile phones, basically adopt a touch screen design. For handwriting input, press the touch screen lightly with your fingers, and the desired content will appear in front of you. Compared with the traditional keyboard design, the touch screen design is more aura, the design is more humanized, and the operation is more convenient. [0003] Finge...
