Although certain embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be construed as being limited to the embodiments described herein. Instead, these embodiments are provided to provide a more thorough and complete understanding of the present application. It should be understood that the drawings and embodiments of the present application are only for exemplary purposes and are not intended to limit the scope of protection of the present application.
[0035] Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.
[0036] Example 1
[0037] like Figure 1-2 As shown, the touch screen structure 100 includes a transparent substrate 10 , a first FPC 30 and a second FPC 40 .
[0038] The transparent substrate 10 has a visible area film sensor 21 corresponding to the visible area 11 and a key area film sensor 22 corresponding to the key area 12 arranged on its back side; wherein a non-touch sensing area 13 is spaced between the visible area 11 and the key area 12, and the length of the space is greater than a first spacing threshold. In a specific example, the first spacing threshold can be preferably 3 mm to improve the applicability of the application.
[0039] The first FPC 30 has one end bound and connected to the visible area film sensor 21 and the other end connected to the touch screen mainboard to transmit the touch signal of the visible area 11 and the key area 12 .
[0040] The second FPC 40 has one end connected to the film sensor 21 in the visible area and the other end connected to the film sensor 22 in the key area to transmit the touch signal of the key area 12 .
[0041] It should be noted that the film sensor is the sensing layer, which is one of the important components of the touch screen. In a specific example, the film sensor can be made of a flexible material, and the ITO on the film sensor is processed into a specific pattern structure to form a sensing unit of the capacitive touch screen.
[0042] It should also be noted that the visible area film sensor 21 includes not only a first wiring for transmitting the visible area touch signal, but also a second wiring for transmitting the key area touch signal. One end of the first wiring is connected to the metal pin bound to the first FPC 30, and the other end is connected to the sensing structure of the visible area film sensor 21; one end of the second wiring is connected to the metal pin bound to the first FPC 30, and the other end is connected to the metal pin bound to the second FPC 40.
[0043] The keyboard area film sensor 22 includes a wiring for transmitting the keyboard area touch signal, one end of which is connected to a metal pin bound to the second FPC 40 , and the other end is connected to the sensing structure of the keyboard area film sensor.
[0044] According to the touch screen structure of the embodiment of the present application, a non-touch sensing area is arranged between the visible area and the key area, and the distance between the two is greater than the first distance threshold; and the second FPC is bound and connected between the visible area film sensor and the key area film sensor to transmit the key area touch signal to the visible area film sensor; and one end of the first FPC is bound and connected to the visible area film sensor to transmit the visible area touch signal and the key area touch signal to the touch screen mainboard. In this way, materials can be saved and costs can be reduced.
[0045] Preferably, the visible area film sensor 21 and the key area film sensor 22 are prepared successively. By preparing them separately, the maximum size capability of the film sensor device for the partitioned touch product can be effectively improved.
[0046] Optionally, the second FPC 40 crosses the non-touch sensing area 13 and forms binding connections with the visible area film sensor 21 and the key area film sensor 22 respectively, so as to take into account a better layout and saving FPC materials.
[0047] As an example, the touch screen structure 100 includes a visible area film sensor 21, N key area film sensors 22, a first FPC 30 and N second FPCs 40, where N≥2. One end of the N second FPCs 40 is respectively bound and connected to the visible area film sensor 21; the other ends of the N second FPCs 40 are respectively bound and connected to the N key area film sensors 22 in a one-to-one correspondence. This is applicable to the application scenario of one visible area film sensor 21 and multiple key area film sensors 22, which can further save materials and reduce costs.
[0048] As another example, the touch screen structure 100 includes N visible area film sensors 21, one key area film sensor 22, N first FPCs 30 and N second FPCs 40, where N≥2. Among them, one end of the N first FPCs 30 is bound and connected to the N visible area film sensors 21 in one-to-one correspondence; the other end of the N first FPCs 30 is bound and connected to the touch screen mainboard; one end of the N second FPCs 40 is bound and connected to the N visible area film sensors 21 in one-to-one correspondence; the other end of the N second FPCs 40 is bound and connected to the key area film sensor 22. It is applicable to the application scenario of multiple visible area film sensors 21 and one key area film sensor 22, which can further save materials and reduce costs.
[0049] Optionally, the sensor pattern structure of the visible area film sensor 21 is different from the sensor pattern structure of the key area film sensor 22. For example, the former may be one of a double bar pattern, a diamond pattern, and other complex patterns, and the latter may be another one of them.
[0050] Optionally, the density of the sensing pattern of the film sensor 21 in the visible area is higher than the density of the sensing pattern of the film sensor 22 in the key area, so as to take into account the functionality of the film sensors in different areas and further save materials and reduce costs.
[0051] Example 2
[0052] This application also provides another touch screen structure. Figure 3-4 As shown, the touch screen structure 100 includes: a transparent substrate 10 , a first FPC 30 and a second FPC 40 .

The first FPC 30 has one end bound and connected to the key area film sensor 22, and the other end is used to connect to the touch screen mainboard; it is used to transmit the touch signal of the visible area 11 and the key area 12. The second FPC 40 has one end bound and connected to the visible area film sensor 21, and the other end is bound and connected to the key area film sensor 22; it is used to transmit the touch signal of the visible area 11.
[0054] It should be noted that the keyboard area film sensor includes not only a third line for transmitting the keyboard area touch signal, but also a fourth line for transmitting the visual area touch signal. One end of the third line is connected to the metal pin bound to the first FPC 30, and the other end is connected to the sensing structure of the keyboard area film sensor; one end of the fourth line is connected to the metal pin bound to the first FPC 30, and the other end is connected to the metal pin bound to the second FPC 40.
[0055] The visible area film sensor 21 includes a wiring for transmitting the visible area touch signal, one end of which is connected to a metal pin bound to the second FPC 40 , and the other end of which is connected to the sensing structure of the visible area film sensor 21 .
[0056] According to the touch screen structure of the embodiment of the present application, a non-touch sensing area is provided between the visible area and the key area, and a second FPC is bound and connected between the visible area film sensor and the key area film sensor to transmit a visible area touch signal to the key area film sensor; and one end of the first FPC is bound and connected to the key area film sensor to transmit a visible area touch signal and a key area touch signal to the touch screen mainboard. Thus, materials can be saved and costs can be reduced.
[0057] As an example, the touch screen structure 100 includes a key area film sensor 22, N visible area film sensors 21, a first FPC 30 and N second FPCs 40, where N≥2. One end of the N second FPCs 40 is respectively bound and connected to the key area film sensor 22; the other ends of the N second FPCs 40 are respectively bound and connected to the N visible area film sensors 21 in a one-to-one correspondence. This is applicable to the application scenario of one key area film sensor 22 and multiple visible area film sensors 21, which can further save materials and reduce costs.
[0058] As another example, the touch screen structure 100 includes N key area film sensors 22, one visible area film sensor 21, N first FPCs 30 and N second FPCs 40, where N≥2. Among them, one end of the N first FPCs 30 is bound and connected to the N key area film sensors 22 in one-to-one correspondence; the other end of the N first FPCs 30 is bound and connected to the touch screen mainboard; one end of the N second FPCs 40 is bound and connected to the N key area film sensors 22 in one-to-one correspondence; the other end of the N second FPCs 40 is bound and connected to the visible area film sensor 21. It is suitable for application scenarios of multiple key area film sensors 22 and one visible area film sensor 21, which can further save materials and reduce costs.
