Embodiment 1

[0055] Such as image 3 and Figure 4 As shown, Embodiment 1 of the present invention proposes a pressure touch screen 300 , the pressure touch screen 300 includes a sealed cavity 310 , a screen main body 320 , a signal acquisition and processing unit 330 and a terminal middle frame 340 .

[0056] Wherein, the sealed cavity 310 is disposed inside the screen main body 310 . Specifically, such as Figure 4 to Figure 6As shown, the screen main body 320 is fastened to the terminal middle frame 340 by sealing foam 350 and glue (not shown), so that the sealed cavity 310 is formed between the terminal middle frame 340 and the inner side of the screen main body 320 . The sealing foam can be PU foam, or CR foam, or EPE foam, so as to ensure the sealing performance of the sealing cavity 310 through a foam structure with good sealing performance.

[0057] The screen main body 320 is mainly used to accept external pressure, and deform under the external force, so that the air pressure ...

Embodiment 2

[0061] Such as Figure 7 and Figure 8 As shown, Embodiment 1 of the present invention proposes a pressure touch screen 400 , which includes a sealed cavity 410 , a screen body 420 , a signal acquisition and processing unit 430 , a terminal middle frame 440 and a linear motor 460 .

[0062] Wherein, the sealed cavity 410 is disposed inside the screen main body 410 . Specifically, such as Figure 8 to Figure 10 As shown, the screen main body 420 is fastened on the terminal middle frame 440 by sealing foam 450 and glue (not shown), so that the sealed cavity 410 is formed between the terminal middle frame 440 and the inner side of the screen main body 420 . The sealing foam can be PU foam, or CR foam, or EPE foam, so as to ensure the sealing performance of the sealing cavity 410 through a foam structure with good sealing performance.

[0063] The screen main body 420 is mainly used for receiving external pressure, and deforms under the external force, so that the air pressure ...

Embodiment 3

[0068] Embodiment 3 of the present invention proposes a mobile terminal. The mobile terminal includes the pressure touch screen 300 in Embodiment 1. The pressure touch screen 300 includes a sealed cavity 310, a screen main body 320, a signal acquisition and processing unit 330, and a terminal Box 340 .

[0069] Wherein, the sealed cavity 310 is disposed inside the screen main body 310 . Specifically, such as Figure 4 to Figure 6 As shown, the screen main body 320 is fastened to the terminal middle frame 340 by sealing foam 350 and glue (not shown), so that the sealed cavity 310 is formed between the terminal middle frame 340 and the inner side of the screen main body 320 . The sealing foam can be PU foam, or CR foam, or EPE foam, so as to ensure the sealing performance of the sealing cavity 310 through a foam structure with good sealing performance.

[0070] The screen main body 320 is mainly used to accept external pressure, and deform under the external force, so that the...

Abstract

The invention discloses a pressure touch screen and a mobile terminal having the same, and belongs to the technical field of touch screens. The pressure touch screen comprises a sealed cavity arrangedon the inner side of a screen body; the screen body which is used for suffering the press of an external force, and deforms under the press of the external force, so as to change the air pressure ofthe sealed cavity; a signal collection and processing element arranged in the sealed cavity, and used for collecting and processing an air pressure variation signal of the sealed cavity into a touch electrical signal. According to the pressure touch screen provided by the invention, the problem that the existing pressure touch screen is low in sensitivity is solved, meanwhile the signal collectionand processing element is arranged in the sealed cavity, so that the stacking thickness of the whole machine is nearly not affected by the signal collection and processing element, and the productioncost is greatly reduced.

Description

technical field [0001] The present invention relates to the technical field of touch screens, in particular to a pressure touch screen and a mobile terminal with the pressure touch screen. Background technique [0002] With the rapid development of mobile terminal touch screen technology, the human-computer interaction methods of mobile terminals are becoming more and more abundant, and more and more touch methods have begun to appear in our field of vision. The first one is the resistive touch screen. , capacitive touch screen, etc., they have been widely used with the development of large-screen mobile terminal technology, and in recent years, another control technology related to human-computer interaction has emerged——pressure touch, making mobile The human-computer interaction mode of the terminal has been enriched again. Many professionals believe that the future of pressure touch has unlimited possibilities and will bring about the next technological revolution in mob...
