Problems solved by technology

However, since the sensing elements are distributed on the same surface of the mobile terminal device, there is a problem of high probability of false triggering of unlocking
In addition, there is a problem of inconvenient use due to the need for specific movements of the finger to complete the detection and realize the unlocking

Embodiment 1

[0065] The inboard of mobile phone casing 3 is provided with induction substrate 4, and induction substrate 4 is connected with capacitive sensor 5, and when finger 2 contacts with mobile phone casing 3, forms contact part 1 (referring to figure 2 ). The mobile phone shell 3 uses plastics. A coupling capacitor is formed between the finger 2 and the sensing substrate 3, and the capacitive sensor 5 detects a small change in capacitance, and sends the detection signal to the microprocessor, and the microprocessor obtains the information of the contact part, and controls the screen unlocking function module (see figure 1 ). Figure 4 Among them, two sensing substrates 4 are respectively arranged on the left side and the right side of the mobile phone to form two detection points. The capacitive sensor 5 obtains two groups of detection signals, and the microprocessor converts the detection signals into the information of the contact part, and compares the information of the con...

Embodiment 2-4

[0069] In Embodiment 2-4, other contents are the same as Embodiment 1 except that the positions and the number of detection points (that is, the number of sensing substrates 4 ) are changed. For details, see Figure 5-7 with table 1.

Abstract

The invention relates to an unlocking device and an unlocking method for mobile terminal equipment. The unlocking device comprises a sensor module, a micro processor and a screen unlocking function module, wherein the screen unlocking function module judges whether to unlock a screen according to a holding posture of a user; and the sensor module comprises at least two sensing substrates which are arranged on at least two surfaces of the mobile terminal equipment. The device is low in false triggering probability, is convenient to use, and can greatly improve the experience of the user.

Description

technical field [0001] The invention relates to an unlocking device and method for mobile terminal equipment. Background technique [0002] At present, the unlocking methods of mobile terminal devices mainly include physical button unlocking and touch slide unlocking (including pattern unlocking). Physical button unlocking is a relatively traditional unlocking method for mobile terminal devices. The operation process is cumbersome, and mechanical wear affects the service life of the mobile phone. Touch sliding unlocking is mainly used for electronic products with a touch screen, and has a novel form. However, this solution is highly dependent on the touch screen. Once the touch screen fails, it will cause unlocking and affect normal use. [0003] The patent application with the application number 201010197917.7 provides a detection algorithm distributed between different sensing points on the same surface (front, side or back). When the user touches these sensing elements w...
