Description
The invention relates to a method and a device for waking up an intelligent terminal and the intelligent terminal.
The existing electronic and electrical products (such as mobile phones, notebook computers, multimedia liquid crystal televisions, numerical control machines and the like) almost have liquid crystal display screens, and the electronic and electrical products can be conveniently and visually operated through the liquid crystal display screens.
For handheld electronic products, such as mobile phones, tablet computers and the like, a battery is used for supplying power, a liquid crystal display screen of the handheld electronic products is a main power consumption component, and in order to enable the handheld electronic products to have good cruising ability, the liquid crystal display screen can be dormant when the display content of the liquid crystal display screen does not need to be watched, namely, the system controls the brightness of a backlight lamp of the liquid crystal display screen by calling a backlight driving function, so that the brightness of the backlight lamp of the liquid crystal display screen is adjusted to be darkest from the current brightness to enter a dormant state, and at the moment, the power consumption of the liquid crystal display screen is the lowest. When the display content of the liquid crystal display screen needs to be watched, the liquid crystal display screen needs to be awakened, at the moment, the system calls and controls the brightness of the backlight lamp of the liquid crystal display screen, so that the brightness of the backlight lamp of the liquid crystal display screen is adjusted from the darkest to the brightness before the dormancy, and the liquid crystal display screen exits from the dormancy state.
With the popularization of the 3rd-generation (3G) network, the internet access speed of the intelligent terminal is faster and faster, and a large number of applications are also in force. The intelligent terminal can replace a personal computer to complete a plurality of functions. The intelligent terminal brings more and more function experiences for users and also brings the disadvantage of higher and higher power consumption speed.
With the increasing popularization of smart phones, the current mobile phone market becomes a buyer market, and how a mobile phone attracts consumers' eyes is critical to performance and experience. Performance is determined by hardware configuration, which determines price, and a relatively good software experience is required to defeat competing partners at the same price. Few consumers pay attention to the sleep and wake-up speed of the liquid crystal screen, however, if a plurality of mobile phones are placed together for comparison, the slow wake-up speed of the mobile phones obviously causes the consumers to feel a delay, and thus the consumers are given an impression: the mobile phone compares the card. Therefore, the wake-up speed of the handset is not insignificant.
As shown in fig. 1, the current general wake-up procedure of a mobile phone is as follows: after receiving the wake-up signal, the liquid crystal display module performs power-on initialization operation to obtain initial parameters, executes a wake-up command in the initial parameters first, executes a liquid crystal display starting command in the initial parameters after the wake-up command is executed, performs system calling, and performs backlight wake-up operation to complete wake-up of the liquid crystal display module. The operation is a single-thread operation mode, the greatest defect of the mode is equal, the asynchronous operation can be performed originally, the asynchronous operation is not required to be connected in series, one after another, and the like, because the linear mode is limited, the intermediate time is not greatly improved even if the intermediate time is compressed, the awakening speed is obviously reduced, especially the awakening speed is reduced on the basis of obtaining the initial parameter, because the timing requirement of the integrated circuit IC (integrated circuit) requires that the parameter takes effect for a period of time after the awakening command parameter is finished, especially under the condition that the waiting time is 70 milliseconds, 80 milliseconds or even hundreds of milliseconds, the whole awakening speed is obviously slowed down, and the user experience is reduced.

Best mode for carrying out the invention
The preferred embodiment of the present invention will be described in detail below with reference to fig. 2 to 4.
The intelligent terminal is an intelligent terminal with a Liquid Crystal Display Module (LCM for short), and can be but is not limited to a mobile phone, a tablet computer, an audio and video player, a handheld game console, a multimedia Liquid Crystal television and the like.
The liquid crystal display module LCM is a component which assembles a liquid crystal display LCD, a connecting piece, a controller, a driving circuit, a PCB circuit board, a backlight source and a structural part together and mainly completes the connecting function of the liquid crystal display.
The liquid crystal display module is divided into a digital display liquid crystal module, a liquid crystal lattice character module and a lattice pattern liquid crystal module.
The digital display liquid crystal module is a functional component which is assembled by a segment type liquid crystal display device and a special integrated circuit into a whole and can only display numbers and some identification symbols. Segment type liquid crystal display devices are mostly applied to portable, pocket-sized devices. Because the device is small, the display part is not designed into a separate component as far as possible, and even if a separate display component is required in some application fields, the device also has functions of receiving, processing, storing and transmitting information and the like besides the display function, and is popular in the market because the device has certain general and specific functions. The common digital display liquid crystal display modules are as follows. 1. The counting module is a counting display component which is assembled by seven-segment liquid crystal display devices with different numbers of bits and a decoding driver or a counter. It has the functions of recording, processing and displaying numbers. The main products in the market of our country are the display module of unit LCD driven by CD4055 decoder, and 4-bit, 6-bit, 8-bit, 10-bit, 12-bit and 16-bit counting module assembled by ICM72ll, ICM7231, ICM7232, CDl4543, UPDl45001, HD44100 and other integrated circuits and corresponding matched LCD. 2. The metering module is a module assembled by a multi-stage liquid crystal display device and an integrated circuit chip with decoding, driving, counting and A/D conversion functions. Because the integrated circuit has A/D conversion function, the input analog quantity electric signal can be converted into digital quantity to be displayed. It is known that any physical quantity, even chemical quantity (such as pH value, etc.) can be converted into analog electric quantity, so that it only needs to be equipped with a certain sensor, and said module can implement regulation and display of any quantity value, and is very convenient for use. The metering module mainly uses integrated circuits such as ICL7106, ICL7116, ICL7126, ICL7136, ICL7135 and ICL7129, and the functions and characteristics of the integrated circuits determine the functions and characteristics of the metering module. As a metered product, it is necessary to perform a metering authentication as specified. The product is approved by the metering department to be pasted with a metering qualification certificate. 3. And the timing module is used for using the liquid crystal display device for the longest timing history, and the liquid crystal display device and a timing integrated circuit are assembled together to form the timer with complete functions. It is called a chronograph module since it does not have the case of a finished timepiece. Although the timing module is widely used, the universal standard timing module is difficult to buy in the market, only the electronic clock production factory can select and buy or order a proper watch core, the timing module and the counting module are similar in appearance, but the display modes of the timing module and the counting module are different, the number displayed by the timing module is composed of a group of two digits, and each digit of the counting module is continuously arranged. Because many timing modules also have timing and control functions, the modules can be widely assembled on some power-on and equipment, such as radio recorders, CD players, microwave ovens, electric cookers and other electric appliances.
The liquid crystal lattice character module is assembled by lattice character liquid crystal display device, special line and column driver, controller and necessary connecting piece, and can display digit and western character. The dot matrix character module is provided with a character generator, and has large display capacity and rich functions. Generally, the module can display characters with 8 bits and 1 line or more than 16 bits and l lines at least. The lattice arrangement of such modules is made up of a 5 x 7, 5 x 8 or 5 x 11 set of pixel lattice arrangements. Each group is 1 bit, there is a little space between each bit, there is a space between each row, so it can't display graphics, generally there is a character library CGROM solidified 192 character models in the module control and driver, and there is also a random access memory CGRAM for user to set up special characters, allowing user to set up 8 characters of 5X 8 lattice.
The dot matrix graphic liquid crystal module is also one of dot matrix modules, and is characterized in that dot matrix pixels are continuously arranged, and no space exists between rows and columns in the arrangement. A continuous, complete graphic can thus be displayed. Since it is also constructed with X-Y matrix pixels, characters can be displayed in addition to graphics. There are several main types: 1. row and column driving type; 2. row and column drive-control type; 3. and a row and column control type.
The liquid crystal display module LCM has the following main parameters:
1. resolution, resolution is a very important performance indicator. It refers to the number of points (lines and planes displayed on the screen are all formed by points) that can be displayed in the horizontal and vertical directions on the screen, and the higher the resolution, the more information can be contained in the same screen. For a CRT capable of supporting 1280 × 1024 resolution, both 320 × 240 and 1280 × 1024 resolution can be expressed perfectly (because the electron beams can be adjusted flexibly). However, its maximum resolution is not necessarily the most suitable resolution, since WINDOWS fonts are small and easily fatigued over time if 1280 × 1024 resolution is achieved on a 17 inch display, the best resolution for a 17 inch display should be 1024 × 768.
2. The contrast ratio, the control integrated circuit IC, the optical filter, the orientation film and other accessories selected during the manufacture of the liquid crystal panel are related to the contrast ratio of the panel, and for general users, the contrast ratio can reach 350:1, but the contrast ratio in the professional field can not meet the requirements of the users. Easily reach 500 relative to CRT displays: 1 or even higher contrast. This is only possible with high-end liquid crystal displays.
3. Brightness, liquid crystal is a substance between solid and liquid states, which is not luminescent by itself, requiring additional light sources. Therefore, the number of lamps is related to the brightness of the LCD. The earliest liquid crystal display only has an upper lamp tube and a lower lamp tube, and the lowest popular liquid crystal display is also a four-lamp type display, and the highest popular liquid crystal display is a six-lamp type display. The design of four lamp tubes is divided into three placing forms: one is that there is a lamp tube on each of four sides, but the disadvantage is that the middle will appear black shadow, the solution is that the four lamp tubes are arranged from top to bottom in parallel, the last one is in a U-shaped arrangement form, which is actually two lamp tubes generated by two lamps changing phase. Six fluorescent tubes are designed to actually use three fluorescent tubes, and manufacturers bend the three fluorescent tubes into a U shape and then place the three fluorescent tubes in parallel to achieve the effect of six fluorescent tubes.
4. The signal response time, which refers to the response speed of the liquid crystal display to the input signal, i.e. the response time of the liquid crystal to change from dark to light or from light to dark, is usually in milliseconds (ms). To say this, we also talk about the perception of the dynamic image by the human eye. The human eyes have the phenomenon of 'vision residue', and pictures moving at high speed can form transient impression in human brain. Until now, the latest games such as cartoons and movies use the principle of visual persistence to make a series of gradually changing images displayed in front of the eyes in rapid succession to form dynamic images. The display speed of the pictures acceptable to people is generally 24 per second, which is the reason of the playing speed of the film at 24 frames per second, and if the display speed is lower than the standard, people can obviously feel the pause and the discomfort of the pictures. The time required for each frame to be displayed is less than 40ms, as calculated by this index. Thus, for the liquid crystal display, the response time of 40ms becomes a threshold, and the display below 40ms has obvious trailing or ghost phenomenon, so that people have chaos. To achieve a smooth image, a speed of 60 frames per second is required.
5. The visual angle and the visual angle of the liquid crystal are a problem of headache, and after the backlight source passes through the polarizer, the liquid crystal and the orientation layer, the output light has directionality. That is, most of the light is vertically emitted from the screen, so that when the liquid crystal display is viewed from a certain large angle, the original color cannot be seen, and even all white or all black can be seen.
The electronic device with a liquid crystal display in this embodiment is described by taking a mobile phone as an example, and the waking method of the liquid crystal display of the electronic device of other types is the same as or similar to the waking method of the liquid crystal display of the mobile phone, which is not described herein again.
At present, a screen is usually awakened (or called turned on) by pressing a power key or pressing a HOME key for a long time, but the service life of the key is easily shortened by pressing the power key or pressing the HOME key for a long time frequently, so that various awakening triggering modes are developed, for example, detecting the change of the gravitational acceleration of the mobile phone to perform awakening triggering, or detecting the position change between the mobile phone and a user to perform awakening triggering, or detecting the change of humidity and temperature to perform awakening triggering and the like.
When the mobile phone system is awakened, the LCD awakening operation and the backlight awakening operation are sequentially carried out, and the system calling is carried out. The LCD wake-up operation and the backlight wake-up operation are performed by sequentially calling an LCD wake-up function and a backlight wake-up function, and the system wakes up the LCD and the backlight by executing the LCD wake-up function and the backlight wake-up function, where LCD wake-up means that the LCD is recovered from a sleep state under the driving of a driving voltage, and an image to be displayed can be normally displayed, and backlight wake-up means that a backlight can be turned on.
The invention provides a method for waking up an intelligent terminal, which has the main idea that single-thread synchronous operation in the process of waking up a mobile phone is optimized into multi-thread asynchronous operation.
The purpose of multithreading is to "maximize the use of CPU resources". Each program execution results in a process, and each process has at least one main thread. The thread is actually a thread executed by the process, and besides the main thread, other threads can be added to the process, that is, other execution threads are added, so that the multi-task function is added to an application program in a certain degree. These threads may be suspended or run after the program is running, depending on various conditions, especially in a multi-CPU environment, where the threads are running concurrently. Multithreading is the process of multiple threads. Thereby enabling an application to have multitasking functions. Multi-process technology can also achieve this, but creates high consumption of processes (each process has independent data and code space), inconvenience of communication between processes (message mechanism), and time for process switching is too long, which leads to the proposition of multi-threading, so that for a single CPU (without turning on hyper-threads), only one thread can be executed at the same time, so if multi-tasking is to be achieved, only one time slice can be obtained for each process or thread, only one thread can be executed at a certain time slice, and then other threads are executed according to a certain policy. This gives the user the perception that there are good multiple threads executing at the same time, since the time slices are very short. However, thread switching is costly, and therefore, if multiple processes are adopted, the memory required by the process to which the thread belongs needs to be switched, which is time-consuming. The thread switching cost is low, and the threads can share the memory. Employing multiple threads is much less expensive to switch than multiple processes. However, thread switching is time consuming, so that the time required to execute with a process having two threads is somewhat longer than the time required to execute twice with a process having one thread. That is, the use of multithreading does not increase the execution speed of the program but decreases the speed, but it is possible for the user to reduce the response time of the user. The result is that the execution speed of the program is improved by adopting the multithreading technology if the single CPU is adopted or the hyper-threading technology is adopted for multiple CPUs or CPUs. Because a single thread is mapped to only one CPU, and multiple threads are mapped to multiple CPUs, the hyper-threading technology is multi-thread hardware in nature, and therefore the execution speed of the program is increased.
As shown in fig. 2, the present invention provides a method for waking up an intelligent terminal, including the following steps:
step S0, the controller sets an asynchronous timer;
step S1, the controller judges whether the wake-up signal is received, if yes, the step S2 is carried out;
step S2, the liquid crystal display module carries out power-on initialization operation to obtain initial parameters;
step S3, the controller executes the awakening command in the initial parameter to make the liquid crystal display module exit the sleep mode;
step S4, after the awakening command takes effect, the controller calls the system, and when the awakening command takes effect, the controller calls the asynchronous timer to execute the liquid crystal display starting command in the initial parameters;
and step S5, the controller performs backlight awakening operation to complete awakening of the liquid crystal display module.
As shown in fig. 3, step S2 specifically includes the following steps:
s2.1, powering on the liquid crystal display module, and resetting hardware;
and S2.2, acquiring initial parameters and carrying out initialization operation.
The initial parameters mainly comprise: wake-up command parameter, liquid crystal display turn-on command parameter, liquid crystal display module driving voltage, display Gamma parameter, and the like.
The wake-up command parameter (sleep out command) corresponds to the sleep command parameter (sleep in command), and the wake-up command parameter is used for enabling the liquid crystal display module to exit from the sleep mode, enabling the setting of the initial parameter to take effect and enabling the internal of the integrated circuit to be boosted.
The liquid crystal display turn-on command parameter (display on command) corresponds to a liquid crystal display module turn-off command parameter (display off command), and the liquid crystal display turn-on command parameter is used for turning on the Liquid Crystal Display (LCD).
The Gamma parameter of the display is a common and important concept in input and output devices such as displays, scanners, printers and the like. The Gamma curve is a special tone curve, and when the Gamma value is equal to 1, the curve is a straight line forming 45 degrees with the coordinate axis, which represents that the input and output densities are the same. Gamma values above 1 will cause the output to be bright and Gamma values below 1 will cause the output to be dark. It is required that the input and output ratio is as close to 1 as possible.
In step S3, the controller calls the wake-up function to execute the wake-up command parameter in the initial parameters, and the wake-up command operation is completed after the wake-up command takes effect.
As shown in fig. 3, the step S4 specifically includes the following steps:
step S4.1, the controller calls an asynchronous timer, sets timing time (in the embodiment, the timing time can be set to 80ms), and after the timing time is reached, the step S4.2 is carried out, and in the timing process of the asynchronous timer, the step S4.3 is synchronously carried out;
