Problems solved by technology

[0003] However, because the bottom of the conductive contact has a certain area, the capacitance change area of ​​the touch panel will cause irregular jitter in the determined position coordinates of the conductive contact during the capacitance dissipation process.
Therefore, when the knob is operated, the system misjudges the rotation angle or position, and then judges that the knob is repeatedly rotated clockwise and counterclockwise, resulting in poor operation fluency of the application program.

Abstract

The invention discloses a working method of a knob device, which comprises the following steps: judging a first position of a conductive contact of a knob, the first position being located on one of aplurality of touch point areas on the surface of a touch panel, the touch point areas being separated from each other and arranged along an arc; after the knob rotates by an angle, judging a second position of the conductive contact of the knob, wherein the second position is located on one of the touch point areas; and when the first position and the second position are respectively positioned on two of the touch point areas, enabling the touch panel to judge whether the knob rotates clockwise or anticlockwise according to the two touch point areas. According to the working method of the knob device, the knob can be prevented from being misjudged to be in the shaking state of repeated clockwise rotation and anticlockwise rotation, and the operation fluency of an application program of the touch panel is improved.

Description

technical field [0001] The present invention relates to a working method of a knob device, in particular to a working method of a knob device used for a touch panel. Background technique [0002] When the traditional knob device is applied to the touch panel, the contact coordinates of the conductive contacts are determined according to the capacitance change generated on the touch panel. Then it is known whether the knob rotates clockwise or counterclockwise through the position and angle change of the conductive contact. [0003] However, because the bottom of the conductive contact has a certain area, the capacitance change area of ​​the touch panel will cause irregular jitter in the determined position coordinates of the conductive contact during the capacitance dissipation process. Therefore, when the knob is operated, the system misjudges the rotation angle or position, and then judges that the knob is repeatedly rotated clockwise and counterclockwise, resulting in po...
