Description

Technical Field

[0001] The utility model relates to a display module, in particular to a touch cover plate structure with a curved touch slider and a display module. Background Art

[0002] With the continuous development of automobile electronics and intelligence, vehicle display modules have become an important part of modern automobiles. Vehicle display modules are not only key tools for displaying vehicle information, but also bear the important responsibility of improving driving experience.

[0003] At present, the slider touch in the touch industry is mainly used in graphic design and is limited by the length of the slider. The longer the slider is, the easier it is to cause position deviation when touching, resulting in the user not being able to touch the exact position, especially for car-mounted touch screens. If the driver needs to touch the touch screen to adjust the temperature, audio and other data in the car during driving, the driver needs to shift his eyes to the touch screen, which will distract the driver and make it easy to cause traffic accidents, increasing safety hazards.

[0021] Figure 3 for Figure 2 FIG. 1 is a schematic diagram of a partially enlarged structure of a touch cover structure with a curved touch slider at point A. FIG. DETAILED DESCRIPTION

[0022] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0023] See also Figure 1 , Figure 2 and Figure 3 As shown, a touch cover structure 10 with a curved touch slider comprises: a cover body 100 and a touch slider structure 200, wherein a display area 110 and a non-display area are provided on the cover body 100, and the cover body 100 has a cover front side 120 and a cover back side 130, and one side edge of the cover body 100 is bent toward one side of the cover front side 120 to form a bent portion 140, and the bent portion 140 is located on the non-display area; the touch slider structure 200 comprises a touch guide groove 210 and a touch sensor 220, wherein the touch guide groove 210 is opened on the cover front side 120, and the touch guide groove 210 is located on the bent portion 140, the touch sensor 220 is attached to the cover back side 130, and the touch sensor 220 is located in the area of ​​the bent portion 140 corresponding to the touch guide groove 210.

[0024] It should be noted that by forming a curved portion 140 on the cover body 110 and opening a touch guide groove 210 for touch guidance on the curved portion 140, the finger's activity space in the X-axis direction can be limited by the touch guide groove 210, and the finger's activity space in the Y-axis direction and the Z-axis direction can be limited by the formed curved portion; in this way, the touch guidance of the user when operating the touch slider structure 200 can be achieved, so as to reduce the distraction caused by the driver's diverting his sight when using it, thereby reducing safety hazards. Among them, the touch sensor 220 plays the role of touch sensing. When the operator's finger touches the touch guide groove 210, the touch sensor 220 will be triggered to start.

[0025] In one embodiment, the touch sensor 220 is attached to the back surface 130 of the cover plate by a double-sided adhesive 230. For example, the double-sided adhesive 230 is a pressure-sensitive adhesive double-sided adhesive.

[0026] In one embodiment, an anti-fingerprint AF coating layer is disposed on the surface of the touch guide groove 210. That is, the anti-fingerprint AF treatment is performed on the surface of the touch guide groove 210, which can not only achieve the anti-fingerprint effect, but also reduce the friction of finger sliding and increase the touch feel.

[0027] In another embodiment, the entire front surface 120 of the cover is provided with an anti-fingerprint AF coating layer. That is, the entire surface of the cover body is coated with an anti-fingerprint AF coating layer, which not only makes the entire surface of the cover body anti-fingerprint, but also reduces the friction of finger sliding on the surface of the touch guide groove to increase the touch feel.

[0028] In one embodiment, a black ink layer 300 is provided on the back side of the cover plate 130. The black ink layer 300 is provided on the non-display area, and the black ink layer 300 plays a role of light shielding decoration. Preferably, the thickness of the black ink layer 300 is 6-8 μm, for example, the thickness of the black ink layer 300 is 7 μm.

[0029] In one embodiment, the touch guide groove 210 is in a strip-shaped structure, and the side walls at both ends of the touch guide groove are in an arc-shaped structure, so that scratches on the operator's hands due to sharp corners can be avoided.

[0030] In one embodiment, the bending angle of the bending portion 140 relative to the cover body 100 is less than 90 degrees. In this way, it is possible to avoid the bending portion 140 being too bent to affect hand operation and block the display area. Preferably, the bending angle of the bending portion 140 relative to the cover body 100 is 45 degrees.

[0031] Furthermore, the cover body 100 is a glass cover. It should also be noted that the processing flow of the touch cover structure in this embodiment is as follows: cutting a small piece of glass on a large plate of glass; pasting an anti-etching protective film on the glass (the area where the touch guide groove 210 needs to be etched is not provided with an anti-etching protective film); using hydrofluoric acid to acid-etch the touch guide groove 210; removing the anti-etching protective film; hot bending one side of the cover body 100 so that one side of the cover body 100 is bent toward one side of the cover front 120 to form a bent portion 140; and then a black ink layer is made by yellow light or pad printing process; after the black ink layer is cured, the touch sensor 220 is double-sidedly pasted on the back of the touch guide groove 210. Among them, the glass cover is acid-etched with hydrofluoric acid, so that a touch guide groove for finger guidance can be made, and the edge micro-cracks caused by the cutting of the passivated glass can also be etched, thereby enhancing the strength of the glass.

[0032] A display module comprises the above-mentioned touch cover plate structure with a curved touch slider, and also comprises a display screen, wherein the display screen is arranged on the back of the cover plate.

[0033] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
