Benefits of technology

The present invention provides a knob device for a touch panel that can be easily integrated with existing systems. The knob device includes a knob cover and a rotation sensing element that is positioned between the touch panel and the knob cover. The rotation sensing element consists of a base and a plurality of sensing pads that are arranged on either the knob cover or the base. When a user touches the knob device, a rotation sensing signal is generated in response to the location of the sensing pads. The knob cover is divided into multiple parts, each containing one of the sensing pads, and each part is connected to another part through a gap. This design allows for more precise sensing and better user experience.

Problems solved by technology

Therefore, how to integrate the knob device and the touch panel to assist user in control has become an issue.
However, digging holes in the glass has disadvantages such as complicated steps, high cost and reduced glass strength.
However, certain problems may occur.
For example, the resolution of the touch panel may be insufficient when the knob is small.
For another example, when the touch pad of the knob is located between two touch panel cells, it is difficult to determine its position.

first embodiment

[0023]Please refer to FIG. 3. FIG. 3 is a cross-sectional view illustrating the knob device 100 arranged on the touch panel 300 according to the present invention. As shown in FIG. 3, the plurality of sensing pads 134 are arranged above the touch panel 300, and abut against or get close to the touch panel 300. In the present embodiment, the plurality of sensing pads 134 abut against the touch panel 300, but the present invention is not limited thereto. The pressing sensing element 150 may be connected to the knob cover 110 and / or the base 300. In the present embodiment, the pressing sensing element 150 is shown connected to the knob cover 110 for better understanding of technical features of the present invention. When the user touches and presses the knob cover 110 of the knob device 100, the pressing sensing element 150 abuts against or gets close to the touch panel 300, such that the touch panel cell(s) 301 under the pressing sensing element 150 generate pressing sensing signal(s...

second embodiment

[0031]Please refer to FIG. 10. FIG. 10 is a top view illustrating the knob device 200 arranged on the touch panel 300 according to the present invention. As shown in FIG. 10, the plurality of sensing pads 234 are arranged on the knob cover 210 and lack an area around a center of the orthographic projection of the knob cover 210. Assume that when the user touches and presses the knob cover 210 of the knob device 200, three touch panel cells 301e, 301f and 301g are under the pressing sensing element 250, such that the three touch panel cells 301e, 301f and 301g generate three sensing signals. The touch panel 300 (particularly, a controller of the touch panel 300) can be pre-programed for generating the pressing sensing signal when receiving three sensing signals generated from three adjacent touch panel cells. Similarly, when the user touches the knob cover 210 of the knob device 200, a touch panel cell 301h is under the plurality of sensing pads 234, such that the touch panel cell 30...

Abstract

A knob device is applicable to a touch panel. The knob device includes a knob cover; and a rotation sensing element. The rotation sensing element includes a base and a plurality of sensing pads connected to the knob cover. The rotation sensing element is arranged between the touch panel and the knob cover. The base is connected to the knob cover. When a user touches the knob device, the touch panel generates a rotation sensing signal in response to a location of the plurality of sensing pads. An orthographic projection of the knob cover on the touch panel is divided into a plurality of parts, the plurality of parts are distributed radially from a center of the orthographic projection of the knob cover, each sensing pad is located in a part and connected to another sensing pad located in another part adjacent to the part.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to U.S. Provisional Patent Application No. 63 / 051,904, filed on Jul. 15, 2020, the disclosure of which is incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION1. Field of the Invention[0002]The present invention relates to a user interface (UI) mechanism design, and more particularly, to a knob device applicable to a touch panel.2. Description of the Prior Art[0003]Knob devices are often used in general electronic apparatus, such as the knob for volume adjustment on an audio player, the knob for frequency adjustment on a radio and the knob for air conditioning / air volume adjustment on a car console, where many of these electronic apparatuses are equipped a touch panel. Therefore, how to integrate the knob device and the touch panel to assist user in control has become an issue. In some traditional methods, the glass of the touch panel has holes on which the knobs are mounted. However...
