Embodiment 1

[0021] Such as figure 1 As shown, this embodiment provides a pressure sensing device for a mobile terminal, the mobile terminal includes a display module 1 and a middle frame 2, the pressure sensing device includes a pressure sensor 3 disposed at the bottom of the middle frame 2, The pressure sensor 3 is pasted on the lower surface of the display module 1 .

[0022] In this embodiment, by affixing the pressure sensor on the lower surface of the display module, it avoids stacking the entire pressure sensing layer on the middle frame of the whole machine, and does not require the middle frame to be made of metal material, nor does it need to be grounded, thereby reducing The requirements on the middle frame of the whole machine are lowered, and the assembly requirements on the whole machine during installation are reduced, so that the pressure sensing device and the mobile terminal of the present invention meet the conditions for mass production.

Embodiment 2

[0024] Such as figure 2 As shown, the difference between the pressure sensing device of the mobile terminal of this embodiment and Embodiment 1 is that: in this embodiment, the display module includes an LCM, and the LCM includes an LCD 4 and a backlight module (i.e., a BackLight module) 5 , the pressure sensor 3 is specifically pasted on the lower surface of the backlight module 5 through the foam glue 6 .

[0025] The bottom of the middle frame 2 is also provided with a flexible insulating substrate 7 on which the pressure sensor 3 is disposed. Preferably, the flexible insulating substrate is a PI substrate.

[0026] A touch sensor 8 is pasted on the upper surface of the LCD4, and the touch sensor 8 is specifically pasted on the upper surface of the LCD4 through a transparent optical glue 9. Glass cover 10.

[0027] In this embodiment, the Vcom layer (reference voltage layer) of the LCD can be selected as the reference terminal of the self-capacitance. When the LCD is pre...

Embodiment 3

[0030] Such as image 3 As shown, the difference between the pressure sensing device of the mobile terminal in this embodiment and Embodiment 2 is that in this embodiment, the display module includes an AMOLED display screen 11 instead of an LCM, and the pressure sensor 3 Specifically, the foam glue 6 is pasted on the lower surface of the AMOLED display screen.

[0031] The bottom of the middle frame 2 is also provided with a flexible insulating substrate 7 on which the pressure sensor 3 is disposed. Preferably, the flexible insulating substrate is a PI substrate.

[0032] A touch sensor 8 is pasted on the upper surface of the AMOLED display screen 11, and the touch sensor 8 is specifically pasted on the upper surface of the AMOLED display screen 11 through a transparent optical glue 9. The upper surface is also provided with a glass cover 10.

[0033] In this embodiment, the cathode of the AMOLED display screen can be selected as the reference terminal of the self-capacitan...

Abstract

The invention discloses a mobile terminal and a pressure sensing device thereof. The mobile terminal comprises a display module and a middle frame. The pressure sensing device is characterized by comprising a pressure sensor arranged at the bottom of the middle frame and attached to the lower surface of the display module. The pressure sensor is attached to the lower surface of the display module, a whole pressure sensing layer is prevented from being stacked on the middle frame of the complete machine, the middle frame is not required to be made of a metal material and grounded, so that the requirement for the middle frame of the complete machine is reduced, the assembly requirement for the complete machine during assembly is reduced, and the pressure sensing device and the mobile terminal have conditions of mass production.

Description

technical field [0001] The invention relates to the technical field of capacitive pressure sensing, in particular to a mobile terminal and a pressure sensing device thereof. Background technique [0002] Capacitive pressure sensing technology provides a new way of human-computer interaction for consumer electronic devices, and can realize three-dimensional operation applications. In the prior art, the pressure sensing layer is usually stacked on the middle frame (front shell) of the electronic device. This setting method has high requirements on the middle frame of the whole machine, including requiring the middle frame to be made of metal, and requiring the middle frame to be grounded, and requiring the middle frame to be as flat as possible and avoid digging holes, which limits the design of the whole machine, resulting in The factory has very strict requirements on the assembly of the whole machine, which makes it difficult to produce in large quantities at present. Con...
