Embodiment 1

[0047] Such as Figure 4 Shown is a specific embodiment of the touch screen of the present invention, Figure 5for Figure 4 Schematic diagram of the rear view structure, Image 6 for Figure 5 Schematic breakdown of the structure.

[0048] see Figure 4 , Figure 5 and Image 6 , In a specific embodiment of the touch screen of the present invention, it includes a touch layer 10 , a base layer 30 opposite to the touch layer 10 , and a conductive layer 20 between the touch layer 10 and the base layer 30 .

[0049] This embodiment adopts a commonly used resistive touch screen structure (referred to as FG, that is, film-to-glass structure), and its upper layer (ie, the surface facing the user after assembly) is a touch layer 10, and the touch layer 10 is sputtered with ITO (ie, indium Tin oxide) polyester film PET (called ITOFilm in the industry), has certain flexibility and good deformation recovery ability.

[0050] The lower layer of the resistive touch screen structur...

Embodiment 2

[0065] This embodiment is a specific embodiment of the touch screen manufacturing process of the present invention. As mentioned earlier, and referring to Image 6 As shown, the touch screen at least includes a touch layer 10 , a conductive layer 20 and a base layer 30 stacked in sequence.

[0066] In this specific embodiment, firstly, the surface of the base layer 30 facing away from the conductive layer 20 is divided into a first area 33 corresponding to the visible window area 11 of the touch screen, and a second area 34 on the outer surface of the first area 33 .

[0067] Thereafter, an insulating film is printed on the first region 33 by using a process such as screen printing to form an insulating layer. The function of the insulating layer is to provide good working conditions for the subsequent process of processing the conductive path 31 .

[0068] Then, a conductive path 31 is formed in the second region 34 through a magnetron sputtering process, and the conductive...

Embodiment 3

[0073] see Figure 4 and Figure 7 As shown, this embodiment is a specific embodiment of the electronic device of the present invention, and the electronic device described in this embodiment is a mobile phone with a touch screen.

[0074] The touch screen with the built-in radio antenna is installed in the front shell of the mobile phone with the touch layer 10 facing the front shell 1 of the mobile phone.

[0075] A mobile phone motherboard is installed on the rear side of the base layer of the touch screen. The radio signal feed point (not shown in the figure) on the main board of the mobile phone connects with the metal shrapnel Figure 5 Connect the radio's antenna feed 32 on the touchscreen as shown in . This completes the connection between the built-in antenna of the radio and the motherboard of the mobile phone.

[0076] Since the mobile phone must also be provided with a mobile phone antenna, in order to overcome the interference of the mobile phone signal and th...

Abstract

The invention discloses a touch screen with a radio built-in antenna. The touch screen comprises at least a touch layer, a base layer arranged opposite to the touch layer, and an electrically conductive layer between the touch layer and the base layer, wherein an electrically conductive path serving as the radio built-in antenna is arranged on one side away from the conductive layer, of the base layer. The space occupied by the radio built-in antenna in an electronic apparatus, such as a mobile phone, can be reduced greatly by forming the electrically conductive path on the idle surface of the base layer of the touch screen and by fully utilizing the existing base layer in the touch screen as the physical carrier of the radio built-in antenna, which is beneficial to the improvement on the thinning degree of the electronic apparatus and lowering the assembly difficulty. The invention also discloses the manufacture process of the touch screen and an electronic apparatus using the touch screen.

Description

technical field [0001] The invention relates to the technical field of communication equipment, in particular to a touch screen with a radio built-in antenna. The present invention also relates to a manufacturing process of the aforementioned touch screen and an electronic device using the aforementioned touch screen. Background technique [0002] At present, portable electronic devices such as mobile phones generally have a frequency modulation stereo (FM radio) function of a radio. Since the high frequency of FM radio is easily affected by obstacles during transmission, the FM stereo (FM radio) function requires portable electronic devices such as mobile phones to be provided with radio antennas (generally referred to as FM antennas for short). [0003] Most of the original mobile phone designs adopt the technical solution of using the external wired earphone as the FM antenna of the mobile phone. When using it, the wired earphone needs to be inserted into the ear hole of...
