Up to this point, mobile terminals have been described in terms of their functionality. 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 100 as shown in fig. 1 may be configured to operate with communication 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, the CDMA wireless communication system may include a plurality of mobile terminals 100, a plurality of Base Stations (BSs) 270, Base Station Controllers (BSCs) 275, and a Mobile Switching Center (MSC) 280. The MSC280 is configured to interface with a Public Switched Telephone Network (PSTN) 290. The MSC280 is also configured to interface with a BSC275, which may be coupled to the base station 270 via a backhaul. The backhaul may be constructed according to any of several known interfaces including, for example, E1/T1, ATM, IP, PPP, frame Relay, HDSL, ADSL, or xDSL. It will be understood that a system as shown in fig. 2 may include multiple BSCs 2750.
Each BS270 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 BS270 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 BS270 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 "cells". Alternatively, each sector of a particular BS270 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 the mobile terminal 100 operating within the system. A broadcast receiving module 111 as shown in fig. 1 is provided at the mobile terminal 100 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 assists in locating at least one of the plurality of mobile terminals 100.
In fig. 2, a plurality of satellites 300 are depicted, but it is understood that useful positioning information may be obtained with any number of satellites. The GPS module 115 as shown in fig. 1 is generally configured to cooperate with satellites 300 to obtain desired positioning information. 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 the wireless communication system, the BS270 receives reverse link signals from various mobile terminals 100. The mobile terminal 100 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 MSC280, which provides additional routing services for interfacing with the PSTN 290. Similarly, the PSTN290 interfaces with the MSC280, the MSC interfaces with the BSCs 275, and the BSCs 275 accordingly control the BS270 to transmit forward link signals to the mobile terminal 100.
Based on the above mobile terminal hardware structure and communication system, the present invention provides various embodiments of the method.
As shown in fig. 3, a first embodiment of the present invention provides a mobile terminal, including:

In the present embodiment, the implementation manner of the sensing module 320 is not limited, for example, the sensing module 320 is a light sensor or a photosensitive layer.
One or more light sensors are disposed below the screen 310, and each light sensor is used for detecting light above at least one touch unit. In this embodiment, the screen may be divided into a plurality of touch units (i.e., touch areas), a light sensor is responsible for monitoring light sensitivity changes of a plurality of touch units, and the arrangement of the touch units and the light sensor may be as shown in fig. 4, where 410 is the light sensor, and 420 is the touch unit divided on the screen 310. The light sensor can sense a light sensing signal above the screen 310 at the first time, when a finger of a user is close to the screen 310 for a certain distance, light and shade change of light on a certain touch unit of the screen can be caused, namely, certain change of light sensing parameters can occur, the light sensing parameters change in different degrees due to different distances, and the light sensor can sensitively sense the light and shade change.
A light sensitive layer is laid below the screen 310 and used for detecting light above the touch units. In this embodiment, the screen 310 is actually a touch screen with its own light sensitive layer: the screen 310 is provided with a photosensitive layer, the photosensitive layer is made of cadmium sulfide, selenium, cadmium selenide sulfide, cadmium sulfide or other materials, the screen 310 is divided into a plurality of touch units, the photosensitive layer is also divided into a plurality of sensing units, and a light sensing signal above the photosensitive layer can be obtained from each sensing unit, as shown in fig. 5, wherein 510 represents a touch unit, and the hatched lines represent the photosensitive layer laid on the screen 310. Because the screen is provided with the photosensitive layer, the light change condition of the monitoring unit of the built-in light sensor is not needed.
Those skilled in the art will appreciate that in order to automatically adjust the screen brightness in a mobile phone, a light sensor or a light-sensitive screen equipped with a light-sensitive layer is generally used. Light sensor or photosensitive layer can be through the change of bright in the discernment environment and generate light sensitive value, operate on the screen that is provided with light sensor or photosensitive layer as object, and different sensitive values will be exported on the photosensitive layer. The number of the light sensors and the size of the photosensitive layer in the embodiment can be set flexibly according to specific actual needs.
