[0036] Please refer to Figure 1-5 A vehicle-mounted ICON screen with touch function structure includes a cover plate 1, an upper polarizer 2, an upper glass 3, a lower glass 4 and a lower polarizer 5. The front and back sides of the upper glass 3 are respectively provided with a touch ITO coating 6 and a display ITO coating 7. The touch ITO coating 6 is provided with a plurality of touch function areas 8. The touch channel wirings 9 of all touch function areas 8 are electrically connected with a touch wiring FPC 10. The display ITO coating 7 is provided with a plurality of ICON icon display areas 11. The back side of the upper glass 3 is provided with a display wiring FPC 12.

[0037] Through the above structural design,;

[0038] like Figure 4 , 5 As shown, the upper glass 3 (large glass) is located on the top, and the glass contains double-sided ITO (touch ITO coating 6 and display ITO coating 7). The upper ITO (touch ITO coating 6) is used for touch function, and the lower ITO (display ITO coating 7) and the upper ITO coating of the lower glass 4 complete the ICON pattern routing;

[0039] like Figure 3 As shown, the touch wiring FPC10 and the display wiring FPC12, the touch wiring FPC10 is led out from the touch ITO coating 6 of the upper glass 3 to realize the touch function; the display wiring FPC12 is led out from the lower ITO layer of the upper glass 3 to realize the ICON pattern display; the touch ITO coating 6 and the display ITO coating 7 are arranged on the front and back sides of the upper glass 3, and the touch ITO coating 6 is used as the touch function SENSOR layer, and there is no need to add an extra layer of SENSOR glass. This patent reduces a layer of SENSOR glass, which is beneficial to saving costs and can reduce the unit price and the overall thickness of the module.

[0040] Specifically, the lower glass 4 is provided with an upper ITO coating for cooperating with the display ITO coating 7 , and all ICON icon display areas 11 and all display channel wirings of the upper ITO coating are electrically connected to the display wiring FPC 12 .

[0041] Through the above structural design, the touch wiring FPC10 and the display wiring FPC12, the touch wiring FPC10 is led out from the touch ITO coating 6 of the upper glass 3 to realize the touch function; the display wiring FPC12 is led out from the lower ITO of the upper glass 3 to realize the ICON pattern display; the touch ITO coating 6 and the display ITO coating 7 are arranged on the front and back sides of the upper glass 3, and the touch ITO coating 6 is used as the touch function SENSOR layer, and there is no need to add an extra layer of SENSOR glass. This patent reduces a layer of SENSOR glass, which is beneficial to saving costs and can reduce the unit price and the overall thickness of the module.

[0042] Specifically, the ICON icon display areas 11 correspond one-to-one to the touch function areas 8 .

[0043] Through the above structural design, each of the ICON icon display areas 11 corresponds to the touch function area 8. The driver can touch and click the corresponding touch function area 8 of the ICON icon display area 11 by observing the icons of the ICON icon display area 11 to realize the function of the virtual button. Specifically, the upper surface of all the ICON icon display areas 11 is provided with touch buttons corresponding to the touch function area 8.

[0044] Through the above structural design, touch buttons can be directly made on the ICON icon display area 11 to replace physical buttons, and the interactive function is more direct and obvious, which is conducive to accurate sensing. Example 2

[0045] The vehicle-mounted ICON screen with touch function structure provided in Example 1 is further optimized, specifically, as follows: Figure 1-5 As shown, openings 13 for cooperating with the rotation button are provided on the left and right sides of the cover plate 1.

[0046] Through the above structural design, the holes 13 on the left and right sides of the cover plate 1 can be used in conjunction with the rotary button, which is beneficial for the driver to save more attention while driving, reduce the probability of traffic accidents, and also realize more operation options.

[0047] Specifically, an explosion-proof membrane 14 is disposed on the top surface of the cover plate 1 .

[0048] Through the above structural design, the explosion-proof film 14 is attached to the cover plate 1 to prevent the glass from breaking and injuring the occupants in the case of collision. The unique micro-displacement of the inter-layer sliding of the explosion-proof film 14 can resolve the impact stress that passes through the glass and acts on the safety film, which can relieve most of the impact and form a unique impact resistance. It is estimated that the glass strength can be enhanced by several hundred times, effectively preventing the glass from breaking and injuring people due to external impact. In order to prevent the glass from self-exploding or being easily shattered when subjected to external force, the most important thing is to relieve the rigidity of the glass and decompose the impact force on the surface. The metal coating of the explosion-proof film 14 and the safety film has good ductility and toughness (especially precious metals such as gold, platinum, silver, titanium, tin, etc.). When subjected to external force, the metal coating can effectively offset and decompose the impact. Even if the glass is broken, the metal material in the explosion-proof film 14 will generate a tensile force, which works together with the colloid of the adhesive layer to pull the glass fragments, so that it is fixed and will not splash, thereby effectively protecting the safety of people and property.

[0049] Specifically, the back surface of the lower polarizer 5 is bonded with the color film 15 via an adhesive layer.

[0050] Through the above structural design, since the ICON screen is a black and white display, in order to realize the color function, a color film 15 can be added to the back of the screen.

[0051] Specifically, the adhesive layer is double-sided adhesive.

[0052] Through the above structural design, the color film 15 and the display screen are double-sidedly bonded, the touch wiring FPC10 and the display wiring FPC12, the touch wiring FPC10 is led out from the touch ITO coating 6 of the upper glass 3 to realize the touch function; the display wiring FPC12 is led out from the lower ITO of the upper glass 3 to realize the ICON pattern display; the touch ITO coating 6 and the display ITO coating 7 are arranged on the front and back sides of the upper glass 3, and the touch ITO coating 6 is used as the touch function SENSOR layer, and there is no need to add an extra layer of SENSOR glass. This patent reduces a layer of SENSOR glass, which is beneficial to saving costs and can reduce the unit price and the overall thickness of the module. Example 3

[0053] The vehicle-mounted ICON screen with touch function structure provided in Example 1 or 2 is further optimized, such as Figure 1-5 As shown, the cover plate 1 and the display screen are fully bonded together by optical adhesive 16 .

[0054] Through the above structural design, the cover plate 1 and the display screen are fully bonded with the optical glue 16. There is a certain space (air layer) between the cover plate 1 and the display screen, which not only affects the screen transparency and causes poor screen display effect, but also makes it easy for dust to enter. In order to overcome the defects of the above frame bonding, the cover plate 1 and the display screen are directly bonded together seamlessly with the optical glue 16.

[0055] Specifically, the touch ITO coating 6 also includes a GND line 17 , and the GND line 17 and the touch channel wiring 9 are staggered.

[0056] Through the above structural design, GND is the abbreviation of the ground terminal of the wire. It represents the ground wire or the zero wire. This ground is not the real ground, but a ground assumed for application. For the power supply, it is the negative pole of the power supply.

[0057] The beneficial effects of the vehicle-mounted ICON screen with touch function structure provided by the utility model are as follows:

[0058] The touch wiring FPC10 and the display wiring FPC12, the touch wiring FPC10 is led out from the touch ITO coating 6 of the upper glass 3 to realize the touch function; the display wiring FPC12 is led out from the lower ITO of the upper glass 3 to realize the ICON pattern display; the touch ITO coating 6 and the display ITO coating 7 are arranged on the front and back sides of the upper glass 3, and the touch ITO coating 6 is used as the touch function SENSOR layer, and there is no need to add an extra layer of SENSOR glass. This patent reduces a layer of SENSOR glass, which is beneficial to saving costs and can reduce the unit price and the overall thickness of the module.
