Description

Technical Field

[0001] The utility model relates to the technical field of mobile phones, in particular to a mobile phone without physical buttons. Background Art

[0002] Currently, mobile phones often have at least one button, which users press to trigger phone operations. The presence of buttons increases the phone's size, given a fixed display screen size. On the other hand, given a fixed phone size, the display screen size decreases. Therefore, existing mobile phone solutions minimize the number of buttons and implement a touchscreen display to facilitate phone operation.

[0024] Example

[0025] like Figure 1-2 As shown, this embodiment provides a mobile phone without physical buttons, including a pressure touch sensor. The pressure touch sensor is connected to the mobile phone's internal bracket 1 and is used to replace the physical buttons of the traditional outer frame 8. One side of the pressure touch sensor is attached to the mobile phone's internal bracket 1 via a first OCA adhesive layer 2, and the other side of the pressure touch sensor is attached to the mobile phone's outer frame 8 via a second OCA adhesive layer 5. The pressure touch sensor has a double-layer film structure, including an upper film structure 3 and a lower film structure 4. A third OCA adhesive layer 6 is provided between the upper and lower film structures 3 and 4. The lower film structure 4 is connected to a touch FPC 7. The touch FPC 7 is connected to the mobile phone's main control FPC, completing the connection.

[0026] Preferably, the pressure touch sensor is a resistive or capacitive touch sensor.

[0027] Preferably, the pressure touch sensor can be partially attached to the outside of the internal bracket 1. That is, the pressure touch sensor can be installed in the traditional physical button area, replacing the physical button area. Correspondingly, the inner side of the phone frame 8, corresponding to the pressure touch sensor area, is provided with a bump structure. This bump structure design can enhance touch sensitivity.

[0028] Preferably, the pressure touch sensor can also be fitted around the four sides of the mobile phone internal bracket 1 to achieve full-frame pressure touch. Accordingly, a circle of convex structures is set on the inner side of the mobile phone frame 8.

[0029] Preferably, the convex dot structure is a circular dot structure or a rectangular structure, and is evenly distributed on the inner side of the mobile phone frame 8.

[0030] Preferably, the touch screen FPC 7 bends backward to the back of the phone's backlight panel, connecting to the main control FPC. Furthermore, preferably, the back of the main control FPC includes a steel reinforcement plate with a roughened surface. The main control FPC is bonded to the phone's casing. The roughened surface of the reinforcement plate facilitates adhesion to the phone's casing and also increases heat dissipation area.
