Embodiment Construction

[0027] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0028] figure 1 Shown is the block diagram of the circuit structure of the preferred embodiment of the mobile terminal of the present invention, as figure 1 As shown in , the mobile terminal includes an optical proximity sensor 100 , a first light source 201 , a second light source 202 and an MCU (micro control unit) 300 .

[0029] The first light source 201 and the second light source 202 in this embodiment use infrared LEDs (light emitting diodes), and those skilled in the art can select different light sources according to needs. In addition, the optical proximity sensor 100 and the MCU 300 are technologies well known to those skilled in the art.

[0030] Wherein the optical proximity sensor 100 is electrically connected with the first light source 201, the second light source 202 a...

Abstract

The invention discloses a mobile terminal and a contactless type keystroke method thereof. The mobile terminal comprises an optical type proximity sensor, a first light source, a second light source and an MCU (Multipoint Control Unit), wherein the first light source and the second light source are electrically connected with the optical type proximity sensor respectively, the optical type proximity sensor is further electrically connected with the MCU, and the first light source, the second light source and the optical type proximity sensor are arranged on the same outside surface of the mobile terminal. The traditional keystrokes which adopt a pressing mode using physical contact have service life, are easy to damage, and are difficult to repair, in addition, contactless type side keys are lacked in the prior art, thus, the invention innovatively provides the mobile terminal and the keystroke method, the real contact with the fingers is not needed, the condition that keystrokes are damaged due to the times of keystroke does not exist, and further, usage experience with richer novelty is brought for users of the mobile terminal.

Description

technical field [0001] The invention relates to a mobile terminal and a non-contact key-press method thereof, in particular to a mobile phone and a non-contact key-press method thereof. Background technique [0002] The side keys used by mobile terminals in the prior art can be divided into three categories: the combination of mechanical roller PC (Flexible Printed Circuit flexible printed circuit board) and metal shrapnel switch, Surface Mountable Side-push Switch (surface mount side key switch) ). The side keys of the above three mobile terminals all adopt the mode of physical contact pressing. The buttons using the physical contact pressing mode have a service life, are not damaged, and are not easy to maintain. In addition, there is a lack of non-contact side buttons in the prior art. Contents of the invention [0003] In order to overcome the defect in the prior art that there is no non-contact side key, the present invention provides a pioneering method for a mobil...
