Fig. 1 illustrates the mobile terminal 100 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 100 will be described in detail below.

The wireless communication unit 110 may generally include one or more components that allow radio communication between the mobile terminal 100 and a wireless communication system or network. For example, the wireless communication unit 110 may include at least one of a broadcast receiving module 111, a mobile communication module 112, a wireless internet module 113, a short-range communication module 114, and a location information module 115.

The broadcast receiving module 111 receives a broadcast signal and/or broadcast associated information 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 broadcast associated information or a server that receives a previously generated broadcast signal and/or broadcast associated information 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 information may also be provided via a mobile communication network, and in this case, the broadcast associated information may be received by the mobile communication module 112. 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 broadcasting-handheld (DVB-H), and the like. The broadcast receiving module 111 may receive a signal broadcast by using various types of broadcasting systems. In particular, the broadcast receiving module 111 may receive digital broadcasting by using a digital broadcasting system such as a data broadcasting system of multimedia broadcasting-terrestrial (DMB-T), digital multimedia broadcasting-satellite (DMB-S), digital video broadcasting-handheld (DVB-H), forward link media (MediaFLO @), terrestrial digital broadcasting integrated service (ISDB-T), and the like. The broadcast receiving module 111 may be constructed to be suitable for various broadcasting systems that provide broadcast signals as well as the above-mentioned digital broadcasting systems. The broadcast signal and/or broadcast associated information received via the broadcast receiving module 111 may be stored in the memory 160 (or other type of storage medium).

The mobile communication module 112 transmits and/or receives radio signals to and/or from at least one of a base station (e.g., access point, node B, etc.), an external terminal, and a server. Such radio signals may include voice call signals, video call signals, or various types of data transmitted and/or received according to text and/or multimedia messages.

The location information module 115 is a module for checking or acquiring location information of the mobile terminal. A typical example of the location information module 115 is a GPS (global positioning system). According to the current technology, the GPS calculates distance information and accurate time information from three or more satellites and applies triangulation to the calculated information, thereby accurately calculating three-dimensional current location information according to longitude, latitude, and altitude. Currently, a method for calculating position and time information uses three satellites and corrects an error of the calculated position and time information by using another satellite. In addition, the GPS can calculate speed information by continuously calculating current position information in real time.

The a/V input unit 120 is used to receive an audio or video signal. The a/V input unit 120 may include a camera 121 and a microphone 122, and the camera 121 processes image data of still pictures or video obtained by an image capturing apparatus in a video capturing mode or an image capturing mode. The processed image frames may be displayed on the display unit 151. The image frames processed by the cameras 121 may be stored in the memory 160 (or other storage medium) or transmitted via the wireless communication unit 110, and two or more cameras 121 may be provided according to the construction of the mobile terminal 100. The microphone 122 may receive sounds (audio data) via the microphone 122 in a phone call mode, a recording mode, a voice recognition mode, or the like, and is capable of processing such sounds into audio data. The processed audio (voice) data may be converted into a format output transmittable to a mobile communication base station via the mobile communication module 112 in case of a phone call mode. The microphone 122 may implement various types of noise cancellation (or suppression) algorithms to cancel (or suppress) noise or interference generated in the course of receiving and transmitting audio signals.

The user input unit 130 may generate key input data to control various operations of the mobile terminal 100 according to a command input by a user. The user input unit 130 allows a user to input various types of information, 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 151 in the form of a layer, a touch screen may be formed.

The sensing unit 140 detects a current state of the mobile terminal 100 (e.g., an open or closed state of the mobile terminal 100), a position of the mobile terminal 100, presence or absence of contact (i.e., touch input) by a user with the mobile terminal 100, an orientation of the mobile terminal 100, acceleration or deceleration movement and direction of the mobile terminal 100, and the like, and generates a command or signal for controlling an operation of the mobile terminal 100. For example, when the mobile terminal 100 is implemented as a slide-type mobile phone, the sensing unit 140 may sense whether the slide-type phone is opened or closed. In addition, the sensing unit 140 can detect whether the power supply unit 190 supplies power or whether the interface unit 170 is coupled with an external device. The sensing unit 140 may include a proximity sensor 141.

The interface unit 170 serves as an interface through which at least one external device is connected to the mobile terminal 100. For example, the external device may include a wired or wireless headset port, an external power supply (or battery charger) port, a wired or wireless data port, a memory card port, a port for connecting a device having an identification module, an audio input/output (I/O) port, a video I/O port, an earphone port, and the like. The identification module may store various information for authenticating a user using the mobile terminal 100 and may include a User Identity Module (UIM), a Subscriber Identity Module (SIM), a Universal Subscriber Identity Module (USIM), and the like. In addition, a device having an identification module (hereinafter, referred to as an "identification device") may take the form of a smart card, and thus, the identification device may be connected with the mobile terminal 100 via a port or other connection means. The interface unit 170 may be used to receive input (e.g., data information, power, etc.) from an external device and transmit the received input to one or more elements within the mobile terminal 100 or may be used to transmit data between the mobile terminal 100 and the external device.

In addition, when the mobile terminal 100 is connected with an external cradle, the interface unit 170 may serve as a path through which power is supplied from the cradle to the mobile terminal 100 or may serve as a path through which various command signals input from the cradle are transmitted to the mobile terminal 100. Various command signals or power input from the cradle may be used as a signal for identifying whether the mobile terminal 100 is accurately mounted on the cradle. The output unit 150 is configured to provide output signals (e.g., audio signals, video signals, alarm signals, vibration signals, etc.) in a visual, audio, and/or tactile manner. The output unit 150 may include a display unit 151, an audio output module 152, an alarm unit 153, and the like.

The display unit 151 may display information processed in the mobile terminal 100. For example, when the mobile terminal 100 is in a phone call mode, the display unit 151 may display a User Interface (UI) or a Graphical User Interface (GUI) related to a call or other communication (e.g., text messaging, multimedia file downloading, etc.). When the mobile terminal 100 is in a video call mode or an image capturing mode, the display unit 151 may display a captured image and/or a received image, a UI or GUI showing a video or an image and related functions, and the like.

Meanwhile, when the display unit 151 and the touch pad are overlapped with each other in the form of a layer to form a touch screen, the display unit 151 may serve as an input device and an output device. The display unit 151 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. Depending on the particular desired implementation, mobile terminal 100 may include two or more display units (or other display devices), for example, mobile terminal 100 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 audio output module 152 may convert audio data received by the wireless communication unit 110 or stored in the memory 160 into an audio signal and output as sound when the mobile terminal 100 is in a call signal reception mode, a call mode, a recording mode, a voice recognition mode, a broadcast reception mode, or the like. Also, the audio output module 152 may provide audio output related to a specific function performed by the mobile terminal 100 (e.g., a call signal reception sound, a message reception sound, etc.). The audio output module 152 may include a speaker, a buzzer, and the like.

The alarm unit 153 may provide an output to notify the mobile terminal 100 of the occurrence of an event. Typical events may include call reception, message reception, key signal input, touch input, and the like. In addition to audio or video output, the alarm unit 153 may provide output in different ways to notify the occurrence of an event. For example, the alarm unit 153 may provide an output in the form of vibration, and when a call, a message, or some other incoming communication (communicating communication) is received, the alarm unit 153 may provide a tactile output (i.e., vibration) to inform the user thereof. By providing such a tactile output, the user can recognize the occurrence of various events even when the user's mobile phone is in the user's pocket. The alarm unit 153 may also provide an output notifying the occurrence of an event via the display unit 151 or the audio output module 152.

The memory 160 may store software programs and the like for processing and controlling operations performed by the controller 180, or may temporarily store data (e.g., a phonebook, messages, still images, videos, and the like) that has been or will be output. Also, the memory 160 may store data regarding various ways of vibration and audio signals output when a touch is applied to the touch screen.

The memory 160 may include at least one type of storage medium including a flash memory, a hard disk, a multimedia card, a card-type memory (e.g., SD or DX memory, etc.), a Random Access Memory (RAM), a Static Random Access Memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM), a magnetic memory, a magnetic disk, an optical disk, and the like. Also, the mobile terminal 100 may cooperate with a network storage device that performs a storage function of the memory 160 through a network connection.

The controller 180 generally controls the overall operation of the mobile terminal. For example, the controller 180 performs control and processing related to voice calls, data communications, video calls, and the like. In addition, the controller 180 may include a multimedia module 181 for reproducing (or playing back) multimedia data, and the multimedia module 181 may be constructed within the controller 180 or may be constructed separately from the controller 180. The controller 180 may perform a pattern recognition process to recognize a handwriting input or a picture drawing input performed on the touch screen as a character or an image.

The power supply unit 190 receives external power or internal power and provides appropriate power required to operate various elements and components under the control of the controller 180.

The various embodiments described herein may be implemented in a computer-readable medium using, for example, computer software, hardware, or any combination thereof. For a hardware implementation, the embodiments described herein may be implemented using at least one of an Application Specific Integrated Circuit (ASIC), a Digital Signal Processor (DSP), a Digital Signal Processing Device (DSPD), a Programmable Logic Device (PLD), a Field Programmable Gate Array (FPGA), a processor, a controller, a microcontroller, a microprocessor, an electronic unit designed to perform the functions described herein, and in some cases, such embodiments may be implemented in the controller 180. For a software implementation, the implementation such as a process or a function may be implemented with a separate software module that allows performing at least one function or operation. The software codes may be implemented by software applications (or programs) written in any suitable programming language, which may be stored in the memory 160 and executed by the controller 180.

Up to this point, the mobile terminal 100 has been described in terms of its functionality. In addition, the mobile terminal 100 in the embodiment of the present invention may be a mobile terminal such as a folder type, a bar type, a swing type, a slide type, and other various types, and is not limited herein.

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, a CDMA wireless communication system may include a plurality of intelligent 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 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 "cells". 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 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 location information module 115 (e.g., GPS) as shown in fig. 1 is generally configured to cooperate with the 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 BS 270 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 is processed within a 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 MSC280 interfaces with the BSCs 275, and the BSCs 275 accordingly control the BS 270 to transmit forward link signals to the mobile terminal 100.

Example one

As shown in fig. 3, the present application provides a display method applied to a mobile terminal, including:

step 301, detecting a current electric quantity value of the mobile terminal in the process of displaying a static picture by the OLED display screen;

step 302, when the current electric quantity value is lower than a preset electric quantity threshold value, converting a part of frame images with intervals in the static picture into preset frame images;

step 303, displaying the still picture after the conversion.

Wherein the predetermined frame image has a luminance at least lower than that of the frame image in the still picture. Specifically, the luminance value of the predetermined frame image is at least lower than that of the frame image before conversion. For example, a predetermined brightness value range or a brightness threshold value may be configured to define the predetermined frame image, and the brightness value range or the brightness threshold value may be set according to actual needs, for example, the brightness value range may be 0 to 10, and the brightness threshold value may be set to 0, so that the brightness of the predetermined frame image is low, which may cause the power consumption of the OLED display screen when displaying the predetermined frame image to be lower than that of an original frame image in a static picture, and the overall power consumption of the OLED display screen may be reduced by converting the interval frame image into the predetermined frame image with low power consumption.

In practical applications, the OLED display will light up every frame refresh. The screen refresh rate of the mobile terminal is generally 60Hz, that is, the OLED display screen is lighted once every 16.6ms, the higher the lighting frequency is, the maximum power consumption of the OLED display screen is, the power consumption of the corresponding mobile terminal is increased, the endurance time of the mobile terminal is short, and the use experience of a user is further influenced. In the embodiment, the static picture is displayed after the partial frame images with intervals in the static picture are converted into the preset frame images, so that under the condition that normal display of the picture is not influenced, the power consumption of the OLED display screen is effectively reduced by reducing the brightness of the picture by utilizing the self-luminous characteristic of the OLED display screen, the power consumption of the mobile terminal in unit time is further reduced, the endurance time of the mobile terminal is effectively prolonged, and the use experience of a user is improved.

The display method in this embodiment is suitable for an OLED display screen to display a static image, where the static image in this embodiment means that a frame image does not change within a certain time (e.g., 1s) or a certain number of consecutive frame images are the same, such as a desktop.

In some implementations, the converting the partial frame image with the interval in the static picture into the predetermined frame image in step 302 can be implemented as follows: selecting one frame image every a predetermined number of frame images in the still picture, and converting the selected frame image into the predetermined frame image. The value of the predetermined number is an integer not less than 1, and may be a fixed value or a dynamically changing random value. In practical applications, a default value may be pre-configured as the predetermined number, or an algorithm for calculating a random value may be pre-configured, and the predetermined number is updated in real time by the algorithm. For example, one original frame image may be converted into the predetermined frame image every other frame image, or one original frame image may be converted into the predetermined frame image every other two original frame images, where the original frame image is a frame image of the still picture before conversion, that is, a frame image of the still picture without any processing.

In practical applications, the screen refresh rate of the mobile terminal is generally 60Hz, that is, the OLED display screen refreshes 60 frames per second, and if each frame of image of the static picture is a color image, the power consumption of the OLED display screen is relatively large. In this embodiment, in the static picture, every certain number of frame images are converted into a predetermined frame image (for example, a black frame image) with relatively low brightness, that is, in 60 frame images refreshed every second, one frame image can be converted into a predetermined frame image (for example, a black frame image) every certain number of frame images, and the other frame images are not changed.

In practical application, because part of frame images in a static picture are converted, and the part of frame images converted into a predetermined frame image are discontinuous, a certain number of original frame images are spaced, and the refresh frequency is higher when the OLED display screen displays the static picture, a user cannot perceive that the predetermined frame image exists in the static picture, so that the power consumption of the OLED display screen in the process of displaying the static picture is reduced on the premise of not influencing the normal display of the static picture and not reducing the user experience.

For example, as shown in fig. 4, in the process of displaying a still picture on the OLED display screen, one of the frame images may be converted into a predetermined frame image every two frame images, and the predetermined frame image may be set as a black frame image.

In some implementations, the conversion of the frame image into the predetermined frame image can be achieved by:

1) pre-configuring the brightness value of the preset frame image; obtaining three primary colors (RGB) values of all pixel points in a frame image to be converted, and updating brightness values in the RGB values of all the pixel points in the frame image to be brightness values of the preset frame image.

2) Pre-configuring RGB values of the preset frame image; and updating the RGB values of all pixel points in the frame image to be converted into the RGB values of the preset frame image.

3) Pre-configuring the RGB value of the preset frame image as the RGB value of a black frame image; and updating the RGB values of all pixel points in the frame image to be converted into the RGB values of the preset frame image.

In practical applications, the conversion of the frame image into the predetermined frame image may also be implemented in other manners, and the specific conversion manner and the conversion process are not limited herein.

In practical application, the process of obtaining the RGB values of all the pixel points of the frame image and updating the RGB values may be performed integrally from the frame layer, or may be implemented by being integrated in a certain application program.

Specifically, the process of acquiring RGB values of all pixel points of the frame image and updating the RGB values may be implemented as follows:

1) starting a designated application program, calling a corresponding Application Programming Interface (API) by the application program and sending the brightness value or RGB value of the preset frame image to an operating system, modifying the brightness value of all the RGB values of all the pixel points of the frame image in the display parameters of the OLED display screen into the brightness value of the preset frame image by the operating system, or modifying all the RGB values of the pixel points of the frame image into the RGB values of the preset frame image, and loading the updated display parameters by the OLED display screen.

2) And directly calling a GUI (graphical user interface) of the OLED display screen, modifying the brightness value of the RGB values of all pixel points of the frame image in the display parameters of the OLED display screen into the brightness value of the preset frame image through the GUI, or modifying the RGB values of all pixel points of the frame image into the RGB values of the preset frame image, and loading the updated display parameters by the OLED display screen.

In this embodiment, after step 301, the method may include: comparing the current electric quantity value with the preset electric quantity threshold value; and when the current electric quantity value is not lower than the preset electric quantity threshold value, directly displaying the static picture, and when the current electric quantity value is lower than the preset electric quantity threshold value, executing step 302. Therefore, when the electric quantity is lower, partial frame images of the static picture are converted, the power consumption of the OLED display screen is reduced, the electric quantity loss of the mobile terminal is further reduced, and the requirement of a user on the duration of electric quantity endurance is met. When the electric quantity is sufficient, any frame of the static picture is not converted, and the display quality of the OLED display screen can be ensured to be optimal so as to meet the requirements of users on the display picture quality, and thus, better user experience can be obtained.
