Abstract
The invention provides a Device and a method for Mobile equipment screen constant brightness display, which is mainly financial commodity quotation software operated on Mobile equipment (Mobile devices) such as Mobile phones, Personal Digital Assistants (PDAs) and the like, and is characterized in that after a user starts the screen constant brightness display function of the Mobile equipment financial commodity quotation software, the software temporarily keeps the screen constant brightness display for a period of time, so that the user can continuously monitor the latest quotation information of financial commodities under the condition of not operating the Mobile equipment, and the screen backlight is not turned off when the Mobile equipment is in a system sleep state because of being idle.
Description
Technical Field
The present invention relates to financial product quotation software for mobile devices, and more particularly, to a device and method for displaying a mobile device with a constant brightness screen.
Background
Currently, mobile device manufacturers and Operating system (Operating Systems) manufacturers use various software and hardware methods to reduce power consumption in order to extend the service time and standby time of mobile devices, including the following techniques: increase battery capacity, use a low-power Central Processing Unit (CPU), use an operating system hibernation mechanism, etc. The operating system sleep mechanism controls the hardware to be turned on/off in a software mode to achieve the effect of saving power consumption, and the controlled hardware comprises screen backlight turning off, a network on-line module turning off, central processing unit operation frequency reduction and the like.
Conventionally, in the idle (idle) condition that the user does not operate the financial quote software for a period of time, the operating system sleep mechanism is automatically triggered to turn off the screen backlight. Although some mobile device operating systems allow the user to adjust the idle time, many mobile device operating systems cannot allow the user to adjust the idle time. For example, when a Sony Ericsson model K810i touch-tone cell phone is not operated for 30 seconds, the os hibernation mechanism turns off the backlight of the cell phone screen. The mobile phone with the model can not allow a user to adjust the idle time by himself, the financial commodity quotation software running on the mobile phone can not allow the user to check quotation information after being idle, the user can awaken a mobile phone screen (turn on screen backlight) by touching the physical key of the mobile device again to allow the user to continue checking the quotation information, and if the mobile device is idle for 30 seconds again, the mobile device enters the dormant state again.
In general, 30 seconds is enough for the user to view the quotation information, but when the user wants to prepare for trading or when the market jumping up/down is large, the user needs to view the latest commodity quotation information at any time, and the continuous staring time can reach 10 minutes or even more than 20 minutes. When using a mobile device with a sleep mechanism, since a user wants that the mobile device does not enter a sleep state and cannot view offer information, the user needs to frequently touch a physical key or a screen (if the mobile device is a screen touch type mobile device) of the mobile device to maintain a constant brightness state of the screen. If the user stares at the disk for 10 minutes continuously and touches the physical key once every 30 seconds, the user needs to touch the physical key 20 times after staring at the disk for 10 minutes, which is very inconvenient for the user.
See fig. 1-3. FIG. 1 is a block diagram of a conventional mobile device and financial instrument bidding software, which is a simplified schematic diagram, and therefore only the relevant components are depicted. The mobile device includes software/hardware that can be roughly divided into four layers, from bottom to top: a Hardware Layer (Hardware Layer)34, a Firmware Layer (Firmware Layer)32, an operating system Layer (operating system Layer)30, and an Application Layer (Application Layer) 28. The Hardware layer 34 includes all Hardware components/devices of the mobile device, such as a Hardware Controller (Hardware Controller)26, a backlight module 24, a network module (not shown), a central processing unit (not shown), a memory module (not shown), a baseband module (not shown), a radio frequency module (not shown), an audio module (not shown), a physical keypad (not shown), a battery module (not shown), etc. (components not directly related thereto are omitted and not shown in the figure).
The hardware controller 26 is responsible for controlling the backlight module 24 and other hardware components/modules, which are directly driven by a Driver (Device Driver) such as the Driver 22 of the firmware layer 32. The os sleep control module 18 is responsible for monitoring/resetting an idle timer (idle timer), and controlling the on/off of the screen through the os API/development kit 16. The virtual machine (virtual machine)14 provides a working environment for executing/operating an application program, such as jvm (Java virtual machine), and the quotation software 10 is an application program running on the virtual machine 14, such as financial commodity quotation software developed in Java. The network connection control module 20 controls network connection in the operating environment of the operating system. The second quotation software 12 is an application that runs directly on the operating system layer 30 without the virtual machine 14, such as apple's iPhone application, Microsoft's Windows Mobile application, and so on. The internal system components of the quotation software one 10 and the quotation software two 12 refer to fig. 2.
FIG. 2 is a block diagram of a conventional system for providing financial instrument quotes, which is a simplified schematic diagram and therefore does not depict non-essential associated components. Wherein, the GUI (Graphical User Interface) processing module 36 is responsible for processing all information presented on the screen of the mobile device; the data receiving/transmitting module 38 is responsible for receiving the information transmitted by the server side and processing the information returned by the user side; the data processing module 40 is responsible for processing the data obtained by the data receiving/transmitting module 38; the input device operation module 42 is responsible for processing the input and operation of the user through the physical keys or touch screen of the mobile device; the network connection module 44 is responsible for handling network connection/disconnection.
Fig. 3 is a flowchart of the operation of the user of the conventional financial product quotation software, which illustrates the operation of the conventional technique and the system sleep mechanism by the specific operation flow after the conventional software is started, please refer to fig. 1 and fig. 2, which includes the following steps:
step 101: executing financial commodity quotation software; the user executes the financial product quotation software (i.e., the quotation software one 10 and the quotation software two 12 of FIG. 1) on the mobile device.
Step 102: starting network connection; when the software is started, the network connection module 44 establishes a network connection.
Step 103: operating the software by a user; after the network connection is established, the user can operate the software, for example, the user enters the "optional stock quotation screen" by physical key or touch screen selection through the input device operation module 42, the data receiving/transmitting module 38 starts to receive the quotation information transmitted by the server and delivers the quotation information to the data processing module 40 for processing the received data, and then the GUI processing module 36 presents the data on the screen of the mobile device. The user can select to switch other functions or pictures by physical keys or touch screen through the input device operation module 42.
Step 104: is idle but time? When the user does not continue to operate, the os sleep control module 18 starts to count an idle timer. If the user continues to operate, the os sleep control module 18 resets the idle timer reset (reset) to zero and returns to step 103, and if the user does not continue to operate and the time counted by the idle timer exceeds the idle time setting of the os, the os sleep control module returns to step 105.
Step 105: the dormancy control module closes the screen backlight; when the idle time-out occurs, the os sleep control module 18 turns off the screen backlight. The mobile device is in a dormant state at this time.
Step 106: is it awake? When the mobile device is in the sleep state, the os sleep control module 18 monitors the input device operation module 42 for an input operation by the user, if "no", the sleep state is maintained, and if "yes", the process goes to step 107.
Step 107: the dormancy control module starts up the screen backlight; when the mobile device wakes up from the sleep state, the os sleep control module 18 turns on the screen backlight and then jumps to step 103.
As can be seen from fig. 1 to 3: conventionally, the financial commodity quotation software of the mobile device does not have the function of controlling the backlight of the screen to be constant, the backlight of the screen is controlled by an operating system (an operating system sleep control module 18), and when the user is idle and time-out, the sleep mechanism of the operating system takes over to process the subsequent operation flow. In order to keep the mobile device from entering the sleep state, the user can only keep the screen bright by a continuous operation method.
In summary, the financial quote software of the prior art mobile device lacks the function of keeping the backlight of the mobile device constantly on, and cannot keep the backlight of the mobile device constantly on when the user needs to look at the mark at any time to check the latest quote information. The user can only frequently touch the physical keys of the mobile device or the touch screen to maintain the backlight brightness state of the screen, which is very inconvenient.
Therefore, there is a need for a financial product quotation software that allows mobile devices to maintain constant screen backlight to meet the potential needs of users operating financial tape reading software.

Detailed Description
The present invention is applicable to: the mobile device may be a mobile device with a Java Virtual Machine (JVM), a mobile device running an Android operating system of Google, an iPhone mobile device of apple, a windows mobile device of microsoft, a Symbian mobile device of Nokia, or other platforms having a public screen backlight control method for developers to write programs by themselves.
The device and the method for displaying the screen of the mobile equipment in a constant brightness mode mainly add a backlight control module in financial commodity quotation software, so that the financial commodity quotation software is not limited by the sleep mechanism of an original operating system and can randomly control the display of the screen in the constant brightness mode, a user can conveniently and continuously stare at the screen when needed, and the sleep setting of the operating system can be adopted when the control function is not started so as to save the power consumption of a power supply.
The invention is mainly to add a backlight control module in the financial commodity quotation software, the module uses the control screen backlight Application Program Interface (API) provided by the mobile device operating system/Virtual Machine (Virtual Machine)/manufacturer software development Kit (Vendor software development Kit) to control the screen backlight. The following will take embodiments of Java, Android, iPhone, Windows Mobile, Symbian Mobile phones, and other platforms as examples.
Please refer to fig. 4, fig. 5, fig. 6, and fig. 7 according to an embodiment of the present invention. FIG. 4 is a block diagram of a mobile device and financial instrument quote software according to the present invention, which is different from FIG. 1 in that: I. a control screen backlight API 46 in the virtual machine 14; control screen backlight API 48 in operating system API/development kit 16. Both the control screen backlight API 46 and the control screen backlight API 48 are originally present in most mobile devices today, which are provided by mobile device manufacturers, operating system vendors, virtual machine vendors, etc., but are not conventionally used in financial commodity pricing software. Taking a Java mobile Device as an example, virtual machine 14 is a Java virtual machine, in which control screen backlight API 46 is included in MIDP (Mobile information Device Profile, a Java API on a mobile Device) or Third Party (Third-Party) Java APIs such as the Nokia UI API.
Taking MIDP version 2.x as an example, the implementation calls a flash backlight () method under the Display object for screen backlight control. An example of program code is as follows:
import javax.microedition.lcdui.Display；
...
flashBacklight(1000)；
...
the above incomplete fragments only refer to the relevant two-stroke order codes, wherein the "import javax.micro edition.lcdui.display" is used for conveniently explaining the origin of the object; "represents, generally, denoted by" importjavax.micro edition.lcdui.; "means. And "flash backlight (1000)" the "1000" in the small parentheses means that the time for turning on the screen backlight is 1,000 milliseconds (millisecond).
Further, taking the Nokia UI API as an example, the screen backlight control program code (incomplete fragment, just related two-stroke code) is as follows:
import com.nokia.mid.ui.DeviceControl；
...
DeviceControl.setLights(0，100)；
...
in the above two examples, the "method" of turning on the screen backlight is called continuously only in a fixed interval, so that the screen backlight of the corresponding Java mobile device can be turned on continuously without being limited by the os hibernation mechanism. For example, each time "method" is called to turn on the backlight for 1000 ms, every 100 ms, the "method" is called again to turn on the backlight for 1000 ms, and the backlight is put into a thread (thread) for execution in a loop manner, so that the effect of screen backlight constant brightness display can be achieved.
In FIG. 4, the operating system layer 30 is provided with the control screen backlight API 48 by the operating system API/development kit 16, such as a Mobile device running the Google Android operating system, an apple iPhone Mobile device, a Microsoft Windows Mobile Mobile device, and a Nokia Symbian Mobile device. Taking Java language development kit of mobile device of Android operating system as an example, it takes four flags (flags) in PowerManager category, such as part _ WAKE _ LOCK (SCREEN backlight off, key backlight off), SCREEN _ DIM _ WAKE _ LOCK (SCREEN backlight on but DIM, key backlight off), SCREEN _ BRIGHT _ WAKE _ LOCK (SCREEN backlight on, key backlight off), FULL _ WAKE _ LOCK (SCREEN backlight on, key backlight on), etc., as SCREEN backlight control, the following is Java program embodiment of segment Android:
PowerManager pm＝(PowerManager)getSystemService(Context.POWER_SERVICE)；
PowerManager.WakeLock wl＝pm.newWakeLock(PowerManager.FULL_WAKE_LOCK，″My Tag″)；
wl.acquire()；
v. when the screen backlight is continuously on
wl.release()；
...
The iPhone mobile device of apple controls the screen backlight with idleTimerDisable, and the program embodiment is as follows:
[UIApplication sharedApplication].idleTimerDisabled＝YES；
the microsoft Windows Mobile device uses BLK1 code to represent the screen backlight module driver, and controls the screen backlight brightness through four power levels D0 to D4, where D0 indicates constant brightness power supply and D4 indicates stopping power supply. The following is an example of the procedure for the fragment Windows Mobile: TCHAR tszBacklightName [ ] ═ TEXT ("BKL 1:");
static HANDLE s_hBacklightReq＝NULL；
s_hBacklightReq＝SetPowerRequirement(tszBacklightName，D0，POWER_NAME，NULL，0)；
ReleasePowerRequirement(s_hBacklightReq)；
the Symbian mobile device of Nokia, like Google Android mobile device, controls the on/off of the screen backlight and the key backlight through the flags, and controls the number of milliseconds of backlight through the time parameters. The following is a program example of the segment Nokia Symbian:
CHWRMLight*iLight＝CHWRMLight::NewL(this)；
light-＞LightOnL(CHWRMLight::ESecondaryDisplay，5000)；
light-＞LightOffL(CHWRMLight::ESecondaryDisplay，5000)；
if there is no time controller in the control screen backlight API (46, 48), such as Android, iPhone, etc., a constant brightness timing module is added in the program to control the time of continuous constant brightness.
FIG. 5 is a block diagram of the financial quote software in accordance with the present invention, which is compared with the prior art FIG. 2, and which is added with a backlight control module 60 that directly calls the control screen backlight API 46 in the virtual machine 14 and the control screen backlight API 48 in the OS API/development kit 16 in the software by the aforementioned method to achieve the purpose of controlling the screen backlight. The backlight control module 60 provides a user with a control function to enable or disable the on-screen backlight highlighting function according to the user's selection, and the control function can be set in a menu (not depicted) of the financial product quotation software for the user to select, and can also be configured to enable or disable the on-screen backlight highlighting function corresponding to a shortcut key of the physical key, such as pressing the button x or pressing the button # or pressing the button twice in succession. When the user starts the screen backlight to be bright by the control function, the financial product quotation software according to the embodiment of the invention is not limited by the sleep mechanism of the operating system, i.e. the screen backlight can be kept bright without being limited by the sleep mechanism of the operating system under the idle condition that the user does not operate the hardware interface.
In summary, the present invention uses a backlight control module 60 to process the control of the screen backlight, and the menu and the hot key provided by the backlight control module allow the user to select to turn on/off the constant brightness function of the screen backlight. The time value is calculated again from the end of the last operation of the user, for example, the duration of each network connection is preset to be "3 minutes", and when the user operates the software 2 minutes after starting (for example, the user switches the top/bottom page of the stock quotation by physical key/touch screen), the time is counted again "3 minutes" after the user operation is ended.
The network online duration setting value and the screen backlight constant brightness display are matched together for operation, the financial commodity quotation software can receive the latest information when the network is kept online, the screen backlight is started to be meaningful, and if a user does not continue the network online, the screen backlight has no starting significance, so the network online duration is actually equal to the screen backlight constant brightness duration. In addition, the invention manages the power consumption of the power supply under the condition of not starting, namely, the sleep mechanism of the operating system, and the power consumption is also managed by the sleep mechanism of the operating system after the time for starting the screen backlight constant-brightness function is out of time.
Fig. 6 is a flowchart of a user operation according to an embodiment of the present invention, in which the user determines whether to control the backlight constant-brightness function of the screen, and the operation flow of the present invention is described by a specific operation flow after software of the embodiment of the present invention is turned on, please refer to fig. 4 and fig. 5, which includes the following steps:
step 201: executing financial commodity quotation software; the user executes the financial product quotation software (quotation software one 10 or quotation software two 12 of fig. 4) on the mobile device.
Step 202: starting network connection; when the software is turned on, the network connection module 58 establishes a network connection.
Step 203: operating the software by a user; after the network connection is established, the user can operate the software, for example, the user selects to enter the "optional stock quotation picture" by physical key or touch screen through the input device operation module 56, the data receiving/transmitting module 52 starts to receive the quotation information transmitted by the server and processes the received data by the data processing module 54, then the GUI processing module 50 presents the quotation data on the screen of the mobile device, and the user can select to switch other functions or pictures by physical key or touch screen through the input device operation module 56.
Step 204: is the screen activated to be constantly bright? When the user starts to operate the software, the user can select whether to start the screen backlight constant brightness function at any time, the start of the screen backlight constant brightness is menu operation or shortcut key operation, the system checks whether the user starts the screen constant brightness function and monitors the input operation of the user by the input device operation module 56, if yes, the step is skipped to step 205; if no, go to step 212.
Step 205: checking a network online time set value; when the user starts the screen brightness keeping function, the backlight control module 60 checks the network on-line time setting value, and loads the value into the memory if the software default value is "90 seconds".
Step 206: resetting/starting a network connection timer; after the time value is loaded into the memory in step 205, the step resets and starts the network connection timer to start timing, and the expiration time of the timer is equal to the value in the memory, which is "90 seconds" in this example.
Step 207: starting the backlight of the screen to be constant bright; when the timer starts, the backlight control module 60 starts the screen backlight constant-brightness function immediately, and the start is as described in the previous embodiments.
Step 208: is the user operated? This step checks whether the user is operating the software with the input device operating module 56, if "yes" then after the user operation jumps back to step 206, resets and starts the timer to recalculate the network duration, if "no" then go to step 209.
Step 209: is the timer expired? After the screen backlight constant-brightness function is started, if the user does not operate the function during the period, the backlight control module 60 checks whether the timer is "90 seconds" up, if yes, the timer resets to zero and jumps to step 210, and if no, returns to step 207 to maintain the screen backlight constant-brightness.
Step 210: interrupting network connection; when the network connection timer is up, the network connection is interrupted.
Step 211: is a network reconnect? After the network connection is disconnected, the dialog box asks the user whether to connect again, if yes, the step 202 is skipped, and if no, the step 212 is skipped.
Step 212: is idle but time? When the user does not continue to operate the input device operating module 56, the os sleep control module 18 starts to count the idle timer, and if the user continues to operate the os sleep control module 18 resets the idle timer to zero and jumps back to step 203, and when the user does not continue to operate the os sleep control module, the time counted by the idle timer exceeds the idle time of the os and then jumps to step 213.
Step 213: the dormancy control module closes the screen backlight; when the idle time expires, the os sleep control module 18 turns off the screen backlight, and the mobile device is in a sleep state.
Step 214: is it awake? When the mobile device is in the sleep state, the os sleep control module 18 monitors the input device operation module 56 for an input operation by the user, and if "no", maintains the sleep state, and if "yes", jumps to step 215.
Step 215: the dormancy control module starts screen backlight; when the mobile device wakes up from the sleep state, the os sleep control module 18 turns on the screen backlight, and then proceeds to step 203.
FIG. 7 is a flowchart illustrating a user operation of another embodiment of the present invention, wherein the operation flow of the embodiment is to permanently keep the backlight of the screen constant after executing software, and the specific operation flow comprises the following steps:
step 301: executing financial commodity quotation software; the user executes the financial product quotation software (quotation software one 10 or quotation software two 12 of fig. 4) on the mobile device.
Step 302: starting the backlight of the screen to be constant bright; when the software is executed, the backlight control module 60 immediately starts the screen backlight dimming function.
Step 303: starting network connection; the network connection module 58 establishes a network connection.
Step 304: operating the software to receive quote information; after the network connection is established, the user can operate the software, for example, the user selects to enter the "optional stock quotation picture" by physical key or touch screen through the input device operation module 56, the data receiving/transmitting module 52 starts to receive the quotation information transmitted by the server and processes the received data by the data processing module 54, then the GUI processing module 50 presents the data on the screen of the mobile device, and the user can select to switch other functions or pictures by physical key or touch screen through the input device operation module 56. In this step, the screen backlight is kept in a constant brightness state no matter how long the idle time is, and the network is also kept in an online state.
In summary, the device and method for displaying and operating the screen constant brightness of the financial commodity quotation software of the mobile device provided by the present invention can enable the mobile device, which is originally limited by the sleep mechanism of the operating system to enter the sleep state when the mobile device is idle, and turns off the screen backlight, to maintain the screen backlight constant brightness display, so that the user can arbitrarily control whether the screen backlight is constantly displayed at any time according to the requirement, and the user can conveniently start the device when needed to stare at the disk at any time without manual operation from time to avoid entering the sleep state. If the user does not start the backlight constant-brightness display function of the screen, the power consumption of the power supply is managed by the sleep mechanism of the operating system, and the function of saving the power consumption of the power supply by the sleep mechanism of the operating system can be still reserved.
The embodiment of the invention is exemplified by a Mobile device with a Java Virtual Machine (JVM), a Mobile device running a Google Android operating system, an apple iPhone Mobile device, a microsoft Windows Mobile device, and a Nokia Symbian Mobile device, which may be a Mobile device with a button or a touch screen, and the rest of the platforms/Mobile devices with a disclosed screen backlight control method for the developer to write program control by himself or utilize the operation mode of the invention.
