Embodiment Construction

[0010] figure 1 A schematic diagram of the stylus of the present invention for use with a touch panel is shown. The stylus 1 of the present invention is applied to a capacitive touch panel (hereinafter referred to as “touch panel”) 3. When the stylus 1 touches the surface of the touch panel 3, the place where the touch panel 3 is pressed may be pressed. Get input information about stylus 1.

[0011] exist figure 1 , the stylus 1 is located on the touch surface 30 of the touch panel 3 , and the pen tip 12 of the stylus 1 is located between the touch panel 3 and the sensing unit S formed at the intersection of one of the scanning electrodes Tx and one of the receiving electrodes Rx in the touch panel 3 form a coupling capacitor. It should be noted here that the touch panel 3 may include a plurality of scanning electrodes Tx arranged parallel to the X axis, and a plurality of receiving electrodes Rx arranged parallel to the Y axis, and the intersection of the scanning electrod...

Abstract

The invention discloses a touch signal processing method and a touch pen, and the touch signal processing method is suitable for being used in a touch pen matched with a touch panel, and comprises thefollowing steps: receiving a transmission signal from the touch panel by using a first signal receiving piece, and generating a first receiving signal; receiving the transmission signal by using a second signal receiving piece and generating a second receiving signal; performing operation on the first receiving signal and the second receiving signal to generate a result value; and sending a driving signal to the touch panel according to the result value so as to carry out touch operation.

Description

technical field [0001] The present invention relates to a signal processing method and a stylus, and more particularly, to a touch signal processing method and a stylus using the aforementioned method. Background technique [0002] The touch screen allows users to perform various functions by touching the touch sensing panel with a finger, a stylus or other objects. Therefore, many electronic devices, such as smart phones or tablet computers, use the touch panel for operation. The interface is operated by the user in a touch-sensitive manner, thereby improving convenience. However, in order to make the operation process of operating the touch panel faster and provide detailed functions such as the thickness of the drawing line and the brush, most users choose the touch pen for touch writing or drawing. [0003] In order to change the thickness of the stroke when the stylus is in use, a pressure sensor is usually installed in the pen case to determine the thickness of the st...
