Description

Technical Field

[0001] The utility model relates to a touch screen component, more specifically, to a high-precision positioning structure of a physical knob for a touch screen. Background Art

[0002] The physical knobs of some central control screens are designed to be attached to the touch screen, and the surface of the touch screen is often coated with AR (anti-reflective film) or AF (anti-fingerprint film). AF will greatly reduce the dyne value of the glass surface, thereby affecting the adhesion of the physical knobs and touch screens. Therefore, the bonding position of the physical knobs and touch screens should avoid AF coating. Before AR or AF coating, a protective film needs to be attached to the physical knobs to avoid this position being covered by AR or AF. However, since the protective film is attached by a fixture, the biggest problem is that workers cannot intuitively judge whether the protective film is offset, which easily causes rework.

[0003] Announcement No. CN216286605U discloses a touch screen ITO pattern and a touch screen that match a physical knob. The touch screen ITO pattern includes a conventional ITO pattern area and a knob ITO pattern area. The knob ITO pattern area is located in the conventional ITO pattern area. The knob ITO pattern of the knob ITO pattern area adopts a single-layer bridge pattern, and the bridge point position of the bridge pattern is located at the center of the knob sensing device. The knob ITO pattern area includes a rotation sensing area and a press sensing area. The rotation sensing area is an annular area, and a plurality of sensing points are evenly arranged in the annular area. Each sensing point corresponds to a bridge point of a bridge pattern, and all bridge points are located on the same loop line of the annular area. The press sensing area is an annular area, and a plurality of sensing points are arranged in the annular area. Each sensing point corresponds to a bridge point of a bridge pattern. The press sensing area is located outside the rotation sensing area, and the press sensing area and the rotation sensing area are concentrically arranged. The conventional ITO pattern of the conventional ITO pattern area adopts a single-layer diamond bridge pattern. The knob ITO pattern is an irregular pattern, each pattern is deformed from a diamond pattern, the sensing channel of the knob ITO pattern is electrically connected to the sensing channel of the corresponding conventional ITO pattern, and the driving channel of the knob ITO pattern is electrically connected to the driving channel of the corresponding conventional ITO pattern. The spacing between the sensing channel and the driving channel of the knob ITO pattern is the same as the spacing between the sensing channel and the driving channel of the conventional ITO pattern, and the parasitic capacitance between adjacent patterns is the same.

[0004] Obviously, this patent changes the position of the ITO capacitor node by adjusting the position of the bridge point in the knob ITO bridging pattern, so that it can accurately sense the position of the knob. This solution cannot solve the problem of the existing protective film offset.

[0005] Publication No. CN112817475A discloses a dynamic exclusion zone for a touch screen physical control, which includes: a touch screen configured to display an on-screen control and receive a touch input; a physical control that at least partially overlaps the touch screen and is further configured to receive a touch input; and a processor that is programmed to: in response to receiving a touch input to the physical control, increase the size of the exclusion zone around the physical control from a default size to an enlarged size greater than the default size, the exclusion zone representing an area of ​​the touch screen within which the touch input to the touch screen is not passed to an application executed by the processor, and in response to not receiving the touch input to the physical control, reduce the size of the exclusion zone from the enlarged size to the default size to allow the touch input to the on-screen control outside the exclusion zone of the default size to be passed to the application. The physical control is conductively coupled to the surface of the touch screen so that the touch screen detects the presence of the user at the physical control as a touch input to the physical control. The physical control is configured to detect the presence of the user at the physical control independently of the touch input function of the touch screen. One or more of the on-screen controls are at least partially displayed within the exclusion zone of the enlarged size. The physical control is a knob control. The touch screen is a capacitive touch screen device.

[0006] Obviously, this patent is used to solve the response problem of the touch screen, but cannot solve the problem of the existing protective film offset. Utility Model Content

The marking circle is a laser circle. Since the diameter of the marking circle is slightly larger than the diameter of the protective film, after the protective film is affixed, it can be determined whether the protective film is offset by confirming whether the protective film is within the circular ring of the marking circle. In addition, since the actual overall periphery of the physical knob is larger than the marking circle, after the knob is bonded, the marking circle will be completely shielded and will not affect the appearance of the product.

[0032] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0033] As described in the background technology, in the prior art, for touch screens, the physical knob buttons of some central control screens are designed to be attached to the touch screen, and the surface of the touch screen is often coated with AR (i.e., anti-reflection and anti-reflection film) or AF (i.e., anti-fingerprint film), wherein AF will greatly reduce the dyne value of the glass surface, thereby affecting the adhesion of the physical knob button to the touch screen. Therefore, the bonding position of the physical knob button and the touch screen should avoid AF coating, and a protective film needs to be attached to the physical knob before AR or AF coating to avoid this position being covered by AR or AF. However, since the protective film is attached by a fixture, the biggest problem is that workers cannot intuitively judge whether the protective film is offset, which easily causes rework.

[0034] In order to solve this technical problem, the utility model provides a high-precision positioning structure for a physical knob of a touch screen, comprising a glass body 1, a circular marking circle 2 is provided on the upper surface of the glass body 1, a circular protective film 3 is attached to the marking circle 2, and the diameter of the marking circle 2 is larger than the diameter of the protective film 3. The marking circle 2 is a laser laser circle, which is laser-etched by a laser device.

[0035] With the above structural design, since the diameter of the marking circle 2 is slightly larger than the diameter of the protective film 3, after the protective film 3 is attached, it can be determined whether the protective film is offset by confirming whether the protective film 3 is within the circular ring of the marking circle 2. In addition, since the actual overall periphery of the physical knob is larger than the marking circle 2, after the knob is attached, the marking circle 2 will be completely covered and will not affect the appearance of the product.

[0036] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

The operation is convenient and is particularly suitable for smaller protective films 3.
