Description

Constant bright display device and method for financial commodity quotation software screen of touch mobile device

technical field

The present invention relates to a touch-sensitive mobile device, in particular to a device and a method for constantly brightly displaying the screen of financial commodity quotation software of the touch-sensitive mobile device.

Background technique

According to the existing touch-sensitive mobile device operating systems, there is a dormancy mechanism, which is used to monitor when the mobile device is idle (idle) and is responsible for turning off the screen backlight (the dormancy mechanism of some operating systems even includes network connection control), to save power consumption. Usually, the idle time setting of the dormancy mechanism is open for the user to choose the setting. For example, the Android operating system (version 1.5) is selected in "Settings" -> "Sound Effects and Display" -> "Screen Timeout" 15 seconds/30 seconds/1 minute/2 minutes/10 minutes/never timeout", as shown in Figure 1. If the user sets the screen timeout to "15 seconds", the mobile device will turn off the screen backlight by the sleep mechanism and enter the sleep mode when the mobile device is idle for more than 15 seconds. If the user sets the screen timeout to "never timeout", it means that the screen backlight will remain on and will not enter sleep mode no matter how long the idle time is. The screen timeout setting of this operating system is that when the time is set longer, the power consumption will be more, that is, the battery life of the mobile device will be shorter. Therefore, most users usually set the screen timeout to "30" less than a second".

None of the existing financial commodity quotation software for touch-sensitive mobile devices provides functions related to the dormancy mechanism, because the existing financial commodity quotation software completely relies on the dormancy mechanism of the operating system, and software developers believe that the financial commodity quotation software does not need to provide and operate Systematic duplication of functionality. However, the dormancy mechanism of the existing touch-sensitive mobile device operating system fails to fully consider user operations in various situations, such as operating financial commodity quotation software/financial commodity order software, and can only choose a common one with a simple setting. User operations in various scenarios cannot satisfy users of financial commodity quotation software.

Generally speaking, in most cases, the user does not spend a long time operating the financial product quotation software. If he only inquires the quotation information of several self-selected stocks, it only takes 20-30 seconds. Therefore, when the screen timeout of the operating system is set to "30 seconds", the user's operations in most situations can be satisfied. However, when the user wants to prepare for a transaction or when the market fluctuates greatly, the user needs to check the latest quotation information at any time, which is generally called "watching the market". In order to prevent the mobile device from entering a dormant state and making it impossible to view quotation information, the user needs to touch the screen of the mobile device frequently to maintain the constant brightness mode of the screen, and the operation time of watching the market is usually about 3 to 5 minutes. If the screen timeout of the above-mentioned operating system is set to "30 seconds", it can meet most situations of operating financial commodity quotation software, but when the user needs to keep an eye on the market, the user needs to touch the screen of the mobile device frequently to maintain constant Bright. If the screen timeout is set to "10 minutes" or "never timeout", although it can meet the user's operation needs when watching the disk (no need to touch the screen frequently to keep the screen on), but in most cases Users do not need the screen to be on for such a long time, especially when the user forgets to manually turn off the screen (for example, put it in the pocket without turning off the screen backlight), the power consumption is not small. Another method of use is: the user sets the screen timeout to "30 seconds", and when there is a need to monitor the disk, then switch to the operating system settings and set the screen timeout to "10 minutes" or "from No timeout", after watching the disk, then change the setting to "30 seconds". However, this kind of operation behavior is extremely inconvenient for users because of the need to switch settings back and forth.

Referring to FIG. 2 , the system block diagram of the existing touch-sensitive mobile device and the financial commodity quotation software, this is a simplified schematic diagram only depicting relevant components. The system architecture of a mobile device can be roughly divided into four layers (Layer), from the bottom layer to the top layer: hardware layer (Hardware Layer) 30, firmware layer (Firmware Layer) 28, operating system layer (Operating System Layer) 26, and application Layer (ApplicationLayer)24. The hardware layer includes the hardware of all mobile devices, such as a hardware controller (HardwareController) 22, a screen backlight module 20, a network module (not depicted), a central processing unit (not depicted), a memory module (not depicted), a baseband module (not depicted) depicted), radio frequency module (not depicted), audio module (not depicted), physical key set (not depicted), battery module (not depicted), etc. (components not directly related here are omitted and not depicted in the figure). Wherein the hardware controller 22 is responsible for controlling the operation of the screen backlight module 20 and other hardware, which can be an integrated controller (as shown in the figure) or an independent controller corresponding to its controlled hardware components respectively, and the hardware controller 22 is The driver program (Device Driver) directly controlled by the firmware layer 28 such as the screen driver program 18 . The dormancy mechanism of the aforementioned touch-sensitive mobile device operating system is processed by the operating system dormancy control module 12, which is responsible for monitoring/resetting the idle timer (Idle Timer), and through the operating system development tool Package/API 14 to control the startup and shutdown of the screen and network (the sleep mechanism of some operating systems also includes network connection control). The most important component in the operating system layer 26 is the operating system development kit (Software Development Kit)/API (Application Programming Interfaces) 14, and the application program (such as quotation software 10) can be completed through this operating system development kit/API 14 Control modules located in the operating system layer 26 , such as the network connection control module 16 . The quotation software 10 is financial commodity quotation software, which is an application program running on the application layer 24 .

FIG. 3 is a system block diagram of the existing financial commodity quotation software, which is a simplified schematic diagram without depicting non-important related components, wherein the screen display module 32 is responsible for processing all information/views (View) presented on the screen of the mobile device. The data receiving/transmitting module 34 is responsible for receiving the information transmitted by the server, and processing the information returned by the client; the data processing module 36 is responsible for processing the data obtained by the data receiving/transmitting module 34 to generate multiple views, For example self-selected stock quote view/best five-gear view/price volume statistics view/technical analysis view/financial news view (not depicted); the input device operation module 38 is responsible for processing the input and input of the user through the physical buttons of the mobile device or the touch screen operate. The network connection module 40 is responsible for processing the connection/disconnection work of the data transmission network (Data Network).

Figure 4 is a flow chart of the user operating the existing financial commodity quotation software, which illustrates the operating process of the existing technology and the system dormancy mechanism with the specific operation process after the existing software is opened, please refer to Figure 2 and Figure 3, which includes The following steps:

Step 101: Execute the financial commodity quotation software; the user executes the financial commodity quotation software (that is, the quotation software 10 in FIG. 2 ) on the touch-sensitive mobile device.

Step 102: Open the network connection; when the software is started, the network connection module 40 establishes a network connection (which includes two network communication protocols, TCP and HTTP).

Step 103: the user operates the software; when the network connection is established, the user can operate the software, for example, the user enters the "self-selected stock quotation view" through the input device operation module 38 through menu operations, and the data receiving/transmitting module 34 begins to receive the data sent by the server. The quotation information is passed to the data processing module 36 to process the received data to generate a self-selected stock quotation view. Then the self-selected stock quotation view is handed over to the screen display module 32 to present the data on the screen of the mobile device. The user can select and switch other functions or views through the input device operation module 38 with physical keys or touch screen.

Step 104: Is idle timeout? When the user does not continue to operate, the operating system dormancy control module 12 starts timing of the idle timer (Idle Timer). If the user continues to operate, then the operating system dormancy control module 12 resets the idle timer to zero and jumps back to step 103, when the user does not continue to operate and the time counted by the idle timer has exceeded the idle time setting of the operating system Then skip to step 105.

Step 105: the dormancy control module turns off the backlight of the screen; when the idle time expires, the dormancy control module 12 of the operating system turns off the backlight of the screen. At this point the mobile device is in sleep mode.

Step 106: wake up? When the mobile device is in the dormant state, the operating system dormancy control module 12 monitors the input device operation module 38 to see if there is user input operation.

Step 107: the sleep control module turns on the screen backlight; when the mobile device wakes up from the sleep state, the operating system sleep control module 12 turns on the screen backlight, and then skips to step 103.

From Fig. 2 to Fig. 4, it can be seen that the existing touch-sensitive mobile device financial product quotation software does not have the function of controlling the constant brightness of the screen backlight, and the screen backlight is controlled by the operating system level (operating system dormancy control module 12). After the timeout, the dormancy mechanism of the operating system takes over to process the subsequent operation process. In order to keep the mobile device from going to sleep, the user can only keep the screen on by continuous operation, or set the "screen timeout" in the settings of the operating system to "10 minutes" or even "never timeout".

If the screen timeout setting of most users is relatively short ("less than 30 seconds") as an example, and the user is continuously watching the disk, then in step 103, frequent operations are required (the interval must be within the screen timeout) Mobile device (for example, touch and slide the screen to turn pages to display the quotation view of self-selected stocks), otherwise it will enter the dormant state; if the screen timeout is set to "10 minutes" or "never timeout", the user will keep an eye on the market At this time, there is no need to frequently operate the mobile device to keep the screen constantly bright, but the user must remember to manually turn off the screen after watching the disk, otherwise the power consumption will be wasted. Or the user sets the screen timeout to "30 seconds", and when there is a need to watch the disk in step 103, switch to the operating system setting and set the screen timeout to "10 minutes" or "never "time", after watching the disk, then change the setting to "30 seconds". However, this kind of operation behavior is extremely inconvenient for the user due to the need to switch settings back and forth.

To sum up, the financial commodity quotation software for touch-sensitive mobile devices in the prior art lacks the function of keeping the screen constantly bright, and needs to be set/managed by the dormancy mechanism at the operating system level, which cannot allow users to easily and automatically monitor the market at any time. Directly turn on the constant brightness mode of the screen in the quotation software. The user can only keep the constant brightness mode of the screen by frequently pressing the physical buttons or the touch screen of the mobile device, which is extremely inconvenient.

Therefore, it is really necessary to propose a financial commodity quotation software that allows touch-sensitive mobile devices to keep the screen constantly bright, so that the constant brightness mode of the screen can be set/controlled in the quotation software, and the control of the constant brightness mode of the screen is controlled by The operating system level is moved to the application level, which is convenient for users to operate nearby, so as to meet the potential needs of users to operate financial commodity quotation software.

Detailed ways

The present invention is used on touch-sensitive mobile devices, such as: mobile phone, PDA, stock machine, smart phone, tablet computer (Tablet PC) or mobile Internet device (Mobile Internet Device/Ultra-MobilePC) etc. financial commodity quotation software 10 , the following is an example of Google's Android mobile device style. Other Microsoft's Windows Phone, Apple's iPhone, BlackBerry (BlackBerry) and other touch-sensitive mobile devices have the same screen features, so no further description and description will be given.

For the embodiment diagram of the present invention, please refer to FIG. 5A and FIG. 5B , which are schematic diagrams of the system setting view 42 of the financial commodity quotation software 10 according to the embodiment of the present invention. It illustrates that the present invention generates a system setting view 42 by receiving a system setting command in the financial commodity quotation software 10, and the system setting view additionally adds a "screen constant brightness mode setting" as shown in FIG. 5A. When the user touches and selects the setting of the constant brightness mode of the screen, a pop-up (Pop-up) a constant brightness mode setting window 44, as shown in FIG. 5B, can be selected to turn on/off the constant brightness of the screen model.

Fig. 5C is a schematic diagram of the time-out reminder window of the screen constant brightness according to the embodiment of the present invention, which illustrates that the constant brightness mode of the screen of the present invention means that the screen is constant brightness for a preset period of time, and when the constant brightness expires, a screen pops up The timeout window 52 is used to ask the user whether to continue to operate in the always-on screen mode.

Fig. 6 is a system block diagram of the touch-sensitive mobile device and the financial commodity quotation software of the present invention, which illustrates that the present invention adds a screen backlight control module 46 to the financial commodity quotation software 10 of the application layer 24, and the screen backlight control module 46 The screen timeout/constant bright mode of the operating system sleep control module 12 used to replace the operating system layer 26 . That is to say, the present invention upgrades the control right of the screen timeout/constant brightness mode from the original operating system layer 26 to the application layer 24, so that users can directly control the setting of the screen constant brightness mode in the financial commodity quotation software 10. In addition, the control screen backlight API 48 in the operating system development kit/API 14 of the operating system layer 26 is an existing API (Application Programming Interfaces), but the financial commodity quotation software 10 of the prior art does not directly use this API Just to control the screen backlight. Taking the Java language development toolkit of mobile devices with the Android operating system (version 1.5) as an example, it uses "PARTIAL_WAKE_LOCK" (screen backlight off, button backlight off), "SCREEN_DIM_WAKE_LOCK" (screen backlight on but slightly dimmed) in the "PowerManager" category. Dark, button backlight off), "SCREEN_BRIGHT_WAKE_LOCK" (screen backlight on, button backlight off), "FULL_WAKE_LOCK" (screen backlight on, button backlight on) and other four flags (Flags) to control the screen backlight, the following is a snippet of Android Java program code example:

PowerManager pm＝(PowerManager)

getSystemService(Context. POWER_SERVICE);

PowerManager.WakeLock wl＝

pm.newWakeLock(PowerManager.FULL_WAKE_LOCK, "My Tag");

wl. acquire();

/*The screen backlight continues to turn on at this time*/

wl. release();

...

The above is only an example of turning on the screen backlight of the Android mobile device. The screen backlight control module 46 of the present invention also adds a constant light timer (not shown in the above program code) to control the time of continuous constant light. For example, this continuous constant light time is "5 minutes" (enough to meet the needs of general staring), when the constant light timer expires (this example is "5 minutes"), the present invention pops up a screen with constant light over A time window 52 is opened to ask the user whether to continue operating the software, as shown in FIG. 5C. And start timing with another idle timer, if the user presses "OK", both the constant light timer and the idle timer will be reset (Reset) to zero, and the constant light timer will start counting again (again "continuous light" 5 minutes"). If the user presses "Cancel" or there is no input, and the set time of the idle timer expires (for example, the idle timeout is "10 seconds"), the screen backlight control module 46 turns off the screen backlight and turns off the constant brightness mode of the screen. The constant brightness mode of the screen of the present invention lasts for a period of time (for example, "5 minutes"). After the time expires, the user is asked whether to continue to operate in the constant brightness mode, which is not the same as the "never timeout" setting of the operating system screen timeout. This mechanism can prevent the user from forgetting to turn off the backlight of the screen for some reason after watching the disk, resulting in waste of power consumption of the screen (for example, putting the mobile device in the pocket without turning off the backlight of the screen).

Fig. 7 is a system block diagram of financial product quotation software according to an embodiment of the present invention. This figure is compared with prior art Fig. 3, and the present invention adds a screen backlight control module 46, and this module is to use the control screen backlight API 48 in the operating system development kit/API 14 of the aforementioned operating system layer 26 to reach the control screen purpose of backlighting. This module also provides a user control function to allow the user to choose to activate or deactivate the constant light display mode according to the needs. The control function can be set in the menu (as shown in Figure 5A and Figure 5B) for the user to choose, and can also be corresponding to an entity The shortcut key of the button, such as the "menu button" (ie, the "Menu" button, not shown, which is one of the standard physical buttons of the Android mobile device) to activate or deactivate the constant light display mode of the screen. When the user starts the backlight of the screen with the control function to keep bright, the financial commodity quotation software 10 in the embodiment of the present invention is not limited by the operating system sleep mechanism, and the user does not need to leave the financial commodity quotation software 10 to switch to the screen timeout setting of the operating system ( As shown in Figure 1), you can control the constant brightness of the screen.

To sum up, the present invention uses a screen backlight control module 46 to handle the control of the screen backlight, which provides menus and shortcut keys for users to choose to enable/disable the constant brightness mode of the screen backlight. The constant brightness duration of the screen of the present invention is preset by the quotation software manufacturer, such as "5 minutes", and its default value of the idle timer that starts counting when the aforementioned screen constant brightness timeout window 52 pops up is also set by the quotation software manufacturer. For example "10 seconds". The present invention manages the overtime time of the screen backlight with the dormancy mechanism of the operating system when it is not started. Not pressing any button) is also handed over to the sleep mechanism of the operating system to manage the screen backlight.

Fig. 8 is a user operation flow chart of the embodiment of the present invention, which illustrates the operation process of the present invention by using the specific operation process after the software of the embodiment of the present invention is started, please refer to Fig. 5A, Fig. 5B, Fig. 5C, Fig. 6 and Fig. 7, which includes the following steps:

Step 201: Execute the financial commodity quotation software; the user executes the financial commodity quotation software (that is, the quotation software 10 in FIG. 6 ) on the touch-sensitive mobile device.

Step 202: Open the network connection; when the software is started, the network connection module 40 establishes a network connection (including two network communication protocols, TCP and HTTP).

Step 203: After the network connection is established, the user can operate the software. For example, the user enters the "self-selected stock quotation view" through the input device operation module 38 through menu operations, and the data receiving/transmitting module 34 starts to receive the quotation information transmitted by the server and The received data is processed by the data processing module 36 to generate a self-selected stock quotation view 50, and then the self-selected stock quotation view 50 is passed to the screen display module 32 to present the data on the screen of the mobile device. The user can select and switch other functions or views through the input device operation module 38 with physical keys or touch screen.

Step 204: Is the startup screen always on? When the user starts to operate the software, he can choose whether to start the constant brightness mode of the screen backlight at any time. The constant brightness of the screen backlight is activated by menu operation (as shown in Figure 5A and Figure 5B) or by quick key operation (not shown), to check the Whether to start the constant brightness mode of the screen is monitored by the input device operation module 38. If it is "yes" to start the constant brightness mode of the screen, then jump to step 205, that is, the control right to turn on the screen backlight duration is handed over to the quotation of the application layer 24 Software 10; if "No", skip to step 212, that is, the control right of the screen backlight on duration is in charge of the operating system layer 26.

Step 205: reset/start the constant bright timer; when the screen is constantly bright, the screen backlight control module 46 resets (reset) and starts the constant bright timer to start counting. constant time.

Step 206: Start the screen backlight constant brightness; when the constant brightness timer starts counting, the screen backlight control module 46 starts the screen backlight constant brightness mode at the same time.

Step 207: Is the timer expired? When the screen backlight constant brightness mode is activated, regardless of whether the user operates during the period, the screen backlight control module 46 controls the continuous constant brightness time of the screen to a fixed value. In this example, the manufacturer’s preset continuous constant brightness time is "5 minutes". , when the screen backlight control module 46 checks whether the constant light timer is "5 minutes", if "yes" the time is up, the constant light timer resets to zero and jumps to step 208, if "no", then returns to step 206 to maintain Screen backlight constant light mode.

Step 208: reset/start the idle timer; when the screen continues to be on for more than "5 minutes", the screen backlight control module 46 resets (reset) and starts another idle timer to start counting. To calculate the idle time after the screen is always on.

Step 209: Do you want to continue the constant light mode? After the timeout of the constant brightness of the screen (in this example, "5 minutes"), the screen backlight control module 46 pops up a timeout window 52 of the constant brightness of the screen to ask the user whether to continue to open the constant brightness mode of the screen, as shown in FIG. 5C . If "Yes" (press "OK" in the legend), then return to step 205, if "No" (press "Cancel" in the legend), then jump to step 211, if it is "other" (that is, no button is pressed), then jump Go to step 210.

Step 210: Is the timer expired? After the idle timer starts counting, if the user does not operate during the period, then the screen backlight control module 46 checks whether the idle timer is idle beyond a set value (for example, preset as "10 seconds"), if "Yes" time is up then The timer resets to zero and jumps to step 211, if "No", then continue timing.

Step 211: Turn off the screen backlight and constant brightness mode; when the user cancels the constant brightness mode (step 209) or the idle timer expires (step 210), the screen backlight control module 46 promptly turns off the screen backlight constant brightness mode and also turns off the screen Backlight (i.e. using Control Screen Backlight API 48). After the constant brightness mode of the screen backlight is turned off, the next time the screen backlight is turned on will be controlled by the operating system dormancy control module 12 of the operating system layer 26 (for example, the screen timeout setting of the operating system in FIG. 1 ).

Step 212: Is idle timeout? When the screen constant brightness mode is closed (i.e. the control right of the screen backlight on duration is taken care of by the operating system), and the user does not continue to operate with the input device operation module 38, the operating system dormancy control module 12 promptly starts the timing of the idle timer, if the user If the operation continues, the operating system dormancy control module 12 resets the idle timer to zero and jumps back to step 203. When the user does not continue to operate and the time counted by the idle timer exceeds the idle time setting of the operating system, then jumps to step 213 .

Step 213: the dormancy control module turns off the backlight of the screen; when the idle time expires, the dormancy control module 12 of the operating system turns off the backlight of the screen, and the mobile device is in a dormant state at this time.

Step 214: wake up? When the mobile device is in the dormant state, the operating system dormancy control module 12 monitors whether the input device operation module 38 has a user's input operation (the Android mobile device presses a physical button to wake up the device), and if "No", then maintains the dormant state , if "yes", then jump to step 215.

Step 215: the dormancy control module turns on the backlight of the screen; when the mobile device is awakened from the dormant state, the dormancy control module 12 of the operating system turns on the backlight of the screen, if the operating system requires the "slide to unlock" step (the slide to unlock can be set in the Android operating system If the screen backlight is turned on, the user must touch and slide in the direction indicated on the screen to unlock it, and then skip to step 203.

To sum up, the device and method for constant bright display and operation of the mobile device financial commodity quotation software screen proposed by the present invention can allow the control of the screen backlight to turn on the duration from the original operating system layer to the quotation software of the application layer. Responsible. Allow users to directly control whether the screen backlight is always on or not from the quotation software according to their needs at any time, without having to switch to the operating system settings, which is convenient for users to start when they need it, so as to keep an eye on the disk at any time without the need for manual operation from time to time to avoid going to sleep. The re-inquiry mechanism after the timeout of the constant bright screen of the present invention can further prevent the waste of power consumption due to the user forgetting to turn off the screen backlight after staring at the disk. If the user does not activate the constant brightness display mode of the screen backlight, the power consumption is managed by the operating system dormancy mechanism, that is, the control right of the screen backlight on duration is in charge of the operating system layer, and the present invention can still retain the operating system dormancy mechanism to save power consumption function.
