The mobile terminal 10 may include, but is not limited to, a memory 20, a controller 30, a wireless communication unit 40, an input unit 50, an input unit 60, a camera 70, a microphone 71, an interface unit 80, and a power supply unit 90. FIG. 1 illustrates a mobile terminal 10 having various components, but it is to be understood that not all illustrated components are required to be implemented. More or fewer components may alternatively be implemented. The elements of the mobile terminal 10 will be described in detail below.

The wireless communication unit 40 typically includes one or more components that allow wireless point communication between the mobile terminal 10 and a wireless communication system or network. For example, the wireless communication unit may include at least one of a broadcast generation module, a mobile communication module, a wireless internet module, a short-range communication module, and a location message module.

The broadcast generation module receives a broadcast signal and/or a broadcast-related message from an external broadcast management server via a broadcast channel. The broadcast channel may include a satellite channel and/or a terrestrial channel. The broadcast management server may be a server that generates and transmits a broadcast signal and/or a broadcast-related message or a server that receives a previously generated broadcast signal and/or broadcast-related message and transmits it to a terminal. The broadcast signal may include a TV broadcast signal, a radio broadcast signal, a data broadcast signal, and the like. Also, the broadcast signal may further include a broadcast signal combined with a TV or radio broadcast signal. The broadcast associated message may also be provided via a mobile communication network, and in this case, the broadcast associated message may be received by the mobile communication module. The broadcast signal may exist in various forms, for example, it may exist in the form of an Electronic Program Guide (EPG) of Digital Multimedia Broadcasting (DMB), an Electronic Service Guide (ESG) of digital video or audio broadcasting handheld (DVB-H), and the like. The broadcast generating module may receive signal broadcasts by using various types of broadcasting systems. In particular, the broadcast generating module may receive digital broadcasts by using a digital broadcasting system such as a multimedia broadcasting-terrestrial (DMB-T), a digital multimedia broadcasting-satellite (DMB-S), a digital video or audio broadcasting-handheld (DVB-H), a data broadcasting system of a forward link media (MediaFLO @), an integrated terrestrial digital broadcasting service (ISDB-T), and the like. The broadcast generating module may be constructed to be suitable for various broadcasting systems providing broadcast signals as well as the above-mentioned digital broadcasting system. The broadcast signals and/or broadcast-related messages received via the broadcast generation module may be stored in the memory 20 (or other type of storage medium).

The short-range communication module is a module for supporting short-range communication. Some examples of short-range communication technologies include bluetooth^TMRadio Frequency Identification (RFID), infrared data association (IrDA), Ultra Wideband (UWB), zigbee^TMAnd so on.

The location message module is a module for checking or acquiring a location message of the mobile terminal. A typical example of the location message module is GPS (global positioning system). According to the current technology, the GPS module calculates distance messages and accurate time messages from three or more satellites and applies triangulation to the calculated messages, thereby accurately calculating a three-dimensional current location message according to longitude, latitude, and altitude. Currently, a method for calculating a position and time message uses three satellites and corrects an error of the calculated position and time message by using another satellite. In addition, the GPS module can calculate the speed message by continuously calculating the current location message in real time.

The display unit 51 may include at least one of a Liquid Crystal Display (LCD), a thin film transistor LCD (TFT-LCD), an Organic Light Emitting Diode (OLED) display, a flexible display, a three-dimensional (3D) display, and the like. Some of these displays may be configured to be transparent to allow a user to view from the outside, which may be referred to as transparent displays, and a typical transparent display may be, for example, a TOLED (transparent organic light emitting diode) display or the like. The mobile terminal 10 may include two or more display units (or other display devices) according to certain desired embodiments, for example, the mobile terminal may include an external display unit (not shown) and an internal display unit (not shown). The touch screen may be used to detect a touch input pressure as well as a touch input position and a touch input area.

The alarm unit 53 may also provide an output notifying the occurrence of an event via the display unit 51 or the audio output module 52.

The input unit 60 may generate key input data to control various operations of the mobile terminal according to a command input by a user. The input unit 60 allows a user to input various types of messages, and may include a keyboard, dome sheet, touch pad (e.g., a touch-sensitive member that detects changes in resistance, pressure, capacitance, and the like due to being touched), scroll wheel, joystick, and the like. In particular, when the touch pad is superimposed on the display unit 50 in the form of a layer, a touch screen may be formed.

Up to now, the mobile terminal has been described in terms of its functions. Hereinafter, a slide-type mobile terminal among various types of mobile terminals, such as a folder-type, bar-type, swing-type, slide-type mobile terminal, and the like, will be described as an example for the sake of brevity. Accordingly, the present invention can be applied to any type of mobile terminal, and is not limited to a slide type mobile terminal.

The mobile terminal 10 as shown in fig. 1 may be configured to operate with systems such as wired and wireless communication systems and satellite-based communication systems that transmit data via frames or packets.

A communication system in which a mobile terminal according to the present invention is operable will now be described with reference to fig. 2.

Such communication systems may use different air interfaces and/or physical layers. For example, the air interface used by the communication system includes, for example, Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), and Universal Mobile Telecommunications System (UMTS) (in particular, Long Term Evolution (LTE)), global system for mobile communications (GSM), and the like. By way of non-limiting example, the following description relates to a CDMA communication system, but such teachings are equally applicable to other types of systems.

Referring to fig. 2, a CDMA wireless communication system may include a plurality of mobile terminals 10, a plurality of Base Stations (BSs) 270, Base Station Controllers (BSCs) 275, and a Mobile Switching Center (MSC) 280. The MSC 280 is configured to interface with a Public Switched Telephone Network (PSTN) 290. The MSC 280 is also configured to interface with BSCs 275, which may be coupled to base stations via a backhaul. The backhaul line may be constructed according to any of several known interfaces, which may include, for example, european/american standard high capacity digital lines (E1/T1), Asynchronous Transfer Mode (ATM), network protocol (IP), point-to-point protocol (PPP), frame relay, high-rate digital subscriber line (HDSL), Asymmetric Digital Subscriber Line (ADSL), or various types of digital subscriber lines (xDSL). It will be understood that a system as shown in fig. 2 may include multiple BSCs 275.

Each BS 270 may serve one or more sectors (or regions), each sector covered by a multi-directional antenna or an antenna pointing in a particular direction being radially distant from the BS 270. Alternatively, each partition may be covered by two or more antennas for diversity reception. Each BS 270 may be configured to support multiple frequency allocations, with each frequency allocation having a particular frequency spectrum (e.g., 1.25MHz, 5MHz, etc.).

The intersection of partitions with frequency allocations may be referred to as a CDMA channel. The BS 270 may also be referred to as a Base Transceiver Subsystem (BTS) or other equivalent terminology. In such a case, the term "base station" may be used to generically refer to a single BSC275 and at least one BS 270. The base stations may also be referred to as "cell sites". Alternatively, each partition of a particular BS 270 may be referred to as a plurality of cell sites.

As shown in fig. 2, a Broadcast Transmitter (BT)295 transmits a broadcast signal to mobile terminals 10 operating within the system. A broadcast generating module 111 as shown in fig. 1 is provided at the mobile terminal 10 to receive a broadcast signal transmitted by the BT 295. In fig. 2, several Global Positioning System (GPS) satellites 300 are shown. The satellite 300 facilitates locating at least one of the plurality of mobile terminals 10.

In fig. 2, a plurality of satellites 300 are depicted, but it is understood that useful positioning messages may be obtained with any number of satellites. The GPS module 115 as shown in fig. 1 is generally configured to cooperate with the satellites 300 to obtain the desired positioning messages. Other techniques that can track the location of the mobile terminal may be used instead of or in addition to GPS tracking techniques. In addition, at least one GPS satellite 300 may selectively or additionally process satellite DMB transmission.

As a typical operation of a wireless communication system, the BS 270 receives reverse link signals from various mobile terminals 10. The mobile terminal 10 is generally engaged in conversations, messaging, and other types of communications. Each reverse link signal received by a particular base station 270 is processed within the particular BS 270. The obtained data is forwarded to the associated BSC 275. The BSC provides call resource allocation and mobility management functions including coordination of soft handoff procedures between BSs 270. The BSCs 275 also route the received data to the MSC 280, which provides additional routing services for interfacing with the PSTN 290. Similarly, the PSTN290 interfaces with the MSC 280, which interfaces with the BSCs 275, and the BSCs 275 accordingly control the BS 270 to transmit forward link signals to the mobile terminal 10.

Based on the above mobile terminal hardware structure and communication system, the present invention provides various embodiments of the method.

Specifically, the array of infrared sensing components 103 is distributed beneath the screen of the mobile terminal 10.

Referring to fig. 4 again, fig. 4 is a schematic diagram of the infrared sensing elements, each infrared sensing element 1030 includes a control chip 1031, an infrared emitter 1032, an infrared receiver 1033, a touch sensor 1034 and a pressure sensor 1035, the infrared emitter 1032, the infrared receiver 1033, the touch sensor 1034 and the pressure sensor 1035 are respectively electrically connected to the control chip 1031, wherein the touch sensor 1034 detects whether a touch operation exists, when the touch operation is detected, a touch signal is generated and sent to the control chip 1031, and the control chip 1031 triggers the infrared emitter and the infrared receiver to enter a working state according to the touch signal.

It should be noted that, after receiving the touch signal, the control chip 1031 generates an electrical signal according to the touch signal and transmits the electrical signal to the central processing unit 1021 of the processing module 102, and the central processing unit 1021 receives the electrical signal, determines a screen position where the touch operation is generated according to the electrical signal, and determines an application program corresponding to the screen position.

It is further added that the setting module 104 sets different pressure thresholds for different security levels, where a pressure threshold is a pressure threshold at which the control chip of the infrared sensor assembly triggers the infrared transmitter and the infrared receiver to enter a working state, and when setting the pressure thresholds for different infrared sensor assemblies according to the security levels, the pressure thresholds may be set according to odd number intervals, or according to rules such as linear decreasing. The pressure sensor 1035 of the infrared sensing component 1030 detects a pressure value corresponding to the pressure signal and transmits the pressure value to the control chip 1031.
