Mobile terminal supporting back control and back control method of mobile terminal

Abstract

The invention discloses a mobile terminal supporting back control and a back control method of the mobile terminal. The mobile terminal comprises a back shell, a display screen and a mainboard, wherein the mainboard is fixed between the back shell and the display screen; the mobile terminal further comprises a rolling ball, a touch switch unit, a photoelectric sensor and a microprocessor; a through hole is formed in the back shell and the rolling ball is embedded into the through hole; the touch switch unit, the photoelectric sensor and the microprocessor are all fixed between the back shell and the display screen; the microprocessor is connected with the mainboard; the photoelectric sensor is connected with the rolling ball and the microprocessor, respectively; the touch switch unit is connected with the rolling ball and the microprocessor, respectively. The mobile terminal supporting the back control has the advantages that the back space of the mobile terminal is utilized thoroughly and the problem that the side edge thickness is limited by a side edge key in the prior art is solved. In addition, blind operations are performed on the back of the mobile terminal; however, the rolling ball control mode provided by the invention is capable of improving the accuracy and usability of the operations, and consequently, the user experience can be enhanced.

Description

【Technical field】 [0001] The invention relates to the field of smart devices, in particular to a mobile terminal supporting back manipulation and a back manipulation method thereof. 【Background technique】 [0002] With the development of communication technology, mobile terminals have played an important role in daily life, especially mobile phones have become an indispensable mobile terminal device in life. The functions of mobile terminals are becoming more and more powerful, and the size of their display screens is also increasing. Taking mobile phones as an example, the screen size of smart phones has exceeded 5 inches. Although touch operations such as sliding and clicking can be performed on the screen, However, this mode of operation becomes less feasible with one-handed operation as the size of the screen becomes larger. In order to improve the operability of smart phones, some buttons are generally set on the side of the phone, such as volume keys, power keys, etc....

AI Technical Summary

Problems solved by technology

The functions of mobile terminals are becoming more and more powerful, and the size of their display screens is also increasing. Taking mobile phones as an example, the screen size of smart phones has exceeded 5 inches. Although touch operations such as sliding and clicking can be performed on the screen, But this mode of operation becomes less feasible with one-handed operation as the screen size becomes larger

In order to improve the operability of smart phones, some buttons are generally set on the side of the phone, such as volume keys, power keys, etc. And the thickness of the side is limited by the structural space occupied by the buttons on the side, so there is a contradiction in the structural design
