Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are for purposes of illustration and not of limitation. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
It should be noted that, for the sake of brevity, this specification is not exhaustive of all of the alternative embodiments, and after reading this specification, one skilled in the art will appreciate that any combination of features may constitute an alternative embodiment as long as the features do not contradict each other.
An optional hardware implementation architecture of the ink screen device in the present solution includes an ink screen, a System On Chip (SOC), a screen driving module, and a power module. The ink screen is a device that directly presents a display screen as described above.
The screen driving module may be an electronic paper display controller (Electronic PaperDisplay controller, EPDC) or a timer control register (Timer Control Register, TCON), also known as a logic board, screen driving board or center control board. In this scheme, the screen driving module is exemplified as EPDC, which is integrated on the EPDC chip.
The screen driving module is connected with the system level chip, receives the waveform lookup table, and then matches corresponding driving waveforms from a preset first waveform lookup table according to the initial gray value and the expected gray value of the pixel. And outputting a screen driving signal to the ink screen based on the driving waveform data, so as to drive pigment particles on the ink screen to move and realize imaging.
The system-in-chip, which is integrated with a main control device such as a central processing unit (central processing unit, CPU) and the like, is a main chip of the ink screen device.
The system on chip may output a waveform look-up table. When the waveform lookup Table is specifically output, the corresponding waveform lookup Table (LUT) is first matched according to the gray level (also called gray level number) or refresh mode of the current display of the screen, and the waveform lookup Table is sent to the screen driving module. The screen driving module matches a corresponding driving waveform (waveform) from the waveform lookup table according to the initial gray value and the gray value to be displayed of the pixel. That is, the screen driving module confirms that the driving waveform at least requires the frame data of the front and rear frames. In addition, the waveform lookup table may be further matched according to the current temperature parameter.
The power supply module supplies power to the screen driving module, and further, can supply power to the system-in-chip. The power module may interface with a power source (external power source or device built-in battery). The power module receives an instruction of the system-in-chip to power the screen driving module or power off the screen driving module.
The signal conversion unit is used for converting a screen driving signal provided by the screen driving module into one or more target driving signals corresponding to interface types based on the interface control signal provided by the system-in-chip, and driving a corresponding ink screen based on the target driving signals, wherein the screen driving signal is obtained by the screen driving module based on the driving waveform data.
The following describes various embodiments of the present invention in detail.
Fig. 1 is a flowchart of a method for switching an operation state of a device according to an embodiment of the present invention. The device operation state switching method is used for a terminal device, particularly for a terminal device using an ink screen for display, namely the ink screen device, and as shown in fig. 1, the device operation state switching method comprises the steps of S110-S150:
step S110: and when the ink screen device is in the operation mode, acquiring current operation data of the ink screen device.
And in the running mode, the ink screen device normally receives user operation and responds and displays the state correspondingly, and the ink screen device has the highest power consumption speed and hardware loss. The whole design of this scheme is under the circumstances that does not influence the whole use of user, avoids maintaining at running mode for a long time as far as possible, enters other lower states of consumption when not influencing the user and uses. And particularly, when the ink screen device is in the operation mode, acquiring current operation data of the ink screen device, wherein the current operation data comprises non-user instruction data such as user interaction frequency, use duration and the like, and also comprises instruction data directly generated by user operation.
Step S120: and matching the current operation data with a preset state switching model.
The specific state switching model is recorded with the data characteristics of various ink screen devices when the ink screen devices can enter a low-power consumption mode, and if the current operation data are consistent with the data characteristics in the state switching model, the operation data before the confirmation are matched with the preset state switching model, so that the mode switching can be performed. The current operation data comprise interval time of sending data to the ink screen, interval time of last detection of control operation by the ink screen equipment and content data of the control operation received by the ink screen; correspondingly, when the current operation data meets the state switching model, the method comprises the following steps: when the interval duration of sending data to the ink screen meets the preset first duration, confirming that the current operation data meets the state switching model; when the interval duration of the last detection of the control operation of the ink screen device meets the preset second duration, confirming that the current operation data meets the state switching model; and when the content data of the control operation received by the ink screen equipment is the content data of the state switching operation, confirming that the current operation data meets the state switching model.
From the aspect of overall design, the ink screen is not required to be displayed for a long time in the scheme, namely the interval duration of sending data to the ink screen meets the preset first duration; the user does not operate the ink screen device for a long time, that is, the interval duration of the ink screen device from the last detection of the control operation meets the preset second duration, and the user receives the explicit state switching operation, both confirm that the state switching is required. The situation can be regarded as that the ink screen device does not need to continue to operate at present from the specific use state or the actual use requirement of a user, and the ink screen device can enter a low-power consumption mode.
The condition for entering the low power consumption mode can be the built-in setting of the system or the self setting and modification of the user. The reference to the duration of the ink screen device entering the standby state can be configured by the system or set by the user. For example, the system on chip of the ink screen device may match the corresponding first duration and/or second duration according to the type of application currently being opened by the ink screen device. For example, the first duration of a reading class application may be shorter than an office class application because the user typically needs to spend a longer time viewing the content in a single screen. The ink screen is a bistable display screen, so that the ink screen can keep the original picture display under the condition of lacking voltage, and the equipment can be standby in a reading gap of a user, so that the power consumption is reduced. Similarly, the type of the document displayed at present can be monitored to match the corresponding first time length, for example, the characters in the document type document are more than the characters in the cartoon type document, and the user can stay longer in a single screen, so the first time length corresponding to the document type document is shorter than the cartoon type document.
As an alternative, when the duration of the continuous operation of the device exceeds the third duration, the device may ask the user whether to enter the low power consumption mode by reminding the user, and when an operation instruction for confirming to enter the low power consumption mode is received or the user does not make an operation instruction for canceling to enter the low power consumption mode within a specified time, the device may enter the low power consumption mode, so that the device can be prevented from running for a long time, and the user can be reminded of rest. The reminding mode of the user can be a mode of popup window through a graphical user interface. That is, when the operation duration of the ink screen device meets a preset third duration, displaying a low-power-consumption confirmation popup window on the ink screen; and when the low-power-consumption confirmation popup receives a control operation confirming to enter a low-power-consumption mode, confirming that the current operation data meets the state switching model.
Step S130: when the current operation data meets the state switching model, saving the picture data of the current display picture of the ink screen equipment and the associated picture waveform data, and interrupting the power supply to the ink screen to enter a low-power consumption mode.
The screen data of the current display screen of the ink screen apparatus includes pixel data, that is, pixel values (gradation values or color values) corresponding to the respective pixels. In the ink screen device, the screen driving module and the data processing module are included, the data processing module includes an image buffer subunit and a data buffer subunit, and the image buffer subunit and the data buffer subunit may be a random access memory (Random Access Memory, abbreviated as RAM), for example, a double data rate synchronous dynamic random access memory (Double Data Rate Synchronous Dynamic Random Access Memory, abbreviated as DDR SDRAM). Of course, a nonvolatile memory (abbreviated as NVM) in an SOC chip, such as a flash memory (flash memory), may also be used. The image buffer subunit and the data buffer subunit can be respectively and independently arranged, can be integrally and independently arranged and split into two functional areas, and can also be integrated in a system-in-chip. When data storage is carried out, saving the picture data of the current display picture of the ink screen equipment to the image buffer subunit; and storing the associated picture waveform data to the data buffer subunit.
Taking the system-on-chip as an example, both the random access memory and the nonvolatile memory of the system-on-chip can maintain target data (i.e., picture data and waveform data). When the working state of the screen driving module is needed, if the target data cannot be read in the RAM of the system-in-chip, the target data related to the display of the ink screen can be read from the NVM and then synchronized to the screen driving module.
It can be understood that the maintenance of the target data is to quickly restore the working state of the screen driving module when the standby state is subsequently exited.
The image data of the current display page includes pixel data of each pixel. When the ink screen is to be switched from the current picture to other pictures, the screen driving module needs to compare the pixel data of the current picture and the picture of the next frame, and sends a driving signal to the ink screen so that the ink screen completes picture updating.
The image data of the current display page is maintained with the following advantages: after the device enters the standby mode, although the screen driving module may be powered off, the ink screen may continue to maintain the current display screen, at this time, after the screen driving module is powered on again, if the system does not maintain the image data of the current display page, then if the screen needs to be refreshed, a problem may occur, because the screen refresh requires the screen driving module to output a driving waveform, and the output of the driving waveform needs to compare the image data (pixel data) of the page before and after the update. Therefore, maintenance of the image data of the currently displayed page is necessary. In the scheme, according to the relatively fixed picture changes before and after the change of the running mode, the waveform data corresponding to the picture changes can be directly recorded, so that the process of confirming the waveform data from the waveform lookup table is further eliminated, and the efficiency in running state switching is improved.
In a specific processing process, besides the waveform data storage corresponding to the picture update under different states, the waveform data among different pages can be further stored. For example, window pages among different applications are switched, two applications are operated before entering a low-power mode, an interface of a first application is displayed after entering the low-power mode, a user can directly enter a window of a second application in the low-power mode, the waveform data corresponding to the interface data of the second application is refreshed by generating the picture data of the interface of the first application in advance, the waveform data is stored, and when the applications are directly switched in the low-power mode, the switching can be rapidly performed. Similarly, adjacent pages of the same application can also be operated in this way quickly, for example, by turning pages in a low power mode. The prerendered page is an associated page with a preset association relation with the current page. In the whole, when the current page is displayed, the display data of the associated page with the preset association relation with the current page is obtained, so that corresponding predicted waveform data (namely waveform data of the prerendered page) can be generated, and the predicted waveform data is cached in a buffer of the screen control module. By generating and caching the waveform data of the page which is possibly displayed next in advance, the generated waveform data can be directly read to finish page display when the page switching actually occurs, the time for generating the waveform data is reduced, and the refresh speed is increased. The associated page is a page which can be obtained through switching or jumping of the current page, such as a front page and a back page. By monitoring the occurrence of different operation events (page switching or jumping), the cache predicted waveform data of the page corresponding to the current operation event can be called at any time. The maintenance of the waveform data of the prerendered page can avoid the need of regenerating the predicted waveform data after the screen driving module is powered on again. Of course, when the target waveform data is confirmed to fail from the associated picture waveform data, the target waveform data corresponding to the page switching relation is generated based on the waveform lookup table, and accordingly display of the ink screen can be achieved.
The system-level chip sends a power-off instruction to the screen driving module to power off the screen driving module, and the equipment enters a standby mode. As an alternative scheme, the system-level chip sends a power failure instruction to the power management module, so that the power management module stops supplying power to the screen driving module, and finally the ink screen driving module is turned off, which also causes the ink screen to lack driving voltage, and further maintains the original display picture.
Step S140: and when a wake-up event is received in the low power consumption mode, confirming target waveform data based on the associated picture waveform data according to the target picture corresponding to the wake-up event and the stored picture data.
When the system-level chip receives the page to be updated, the equipment needs to be out of the low-power mode, and the power management module is used for powering up the screen driving module again. And compared with the current display page, the page to be updated has pixels with different gray values. Pixels having different gray values are referred to herein as being the image information ultimately received by the screen drive module. It will be appreciated that if the system on chip receives a new page image, but only a portion of the background color changes, the image to be updated obtained after the new page image is processed (e.g., gray-scale processed) by the color processor does not substantially change, which is not counted as a wake-up trigger event. The wake event may also be a trigger of a user operation instruction, such as a user pressing a lock screen key on the device, causing a wake trigger event to occur. Also included herein are special wake-up times, for example, the user may set a standby exit time for the device during which the user may take a break.
Step S150: and restoring the power supply to the ink screen and updating a display picture according to the target waveform data.
And after the screen driving module is powered on again, carrying out data recovery. The system level chip resends the previously saved data to the screen driving module. Of course, the screen driving module may directly load the data stored in the nonvolatile memory. In general, when existing waveform data exists, intended display can be realized, the existing waveform data can be directly displayed.
In the scheme, all states with lower power consumption than the running mode can be defined as low power consumption modes, and switching logic between each low power consumption mode and the normal running mode is the same. The sleep mode can be further set on the basis of the low-power mode, and the sleep mode is lower in energy consumption compared with the low-power mode. The running mode can directly enter the sleep mode according to the user operation, or can automatically enter the sleep mode under the condition that the user operation cannot be detected after the low-power consumption mode is entered for a period of time, namely, the sleep switching event can be an event which occurs with time, or can be an event that the user actively operates and is detected by the ink screen device. When a sleep switching event is received in the operation mode, saving picture data of a current display picture of the ink screen equipment and associated picture waveform data, controlling the ink screen to display a screen saver picture, interrupting power supply to the data processing module, adjusting the operation state of a processor of the ink screen equipment and entering a sleep mode; and when a recovery event is received in the sleep mode, recovering power supply to the ink screen, and updating a display picture according to recovery waveform data corresponding to the recovery event. The processing procedures between the sleep mode and the low power consumption mode and the running mode are basically the same, and the main difference is that a specified picture is statically displayed in the sleep mode, and a picture actually watched by a user is displayed in the low power consumption mode. In the specific implementation process, waveform data of a current display picture refreshed to a designated picture can be generated in the operation process, and the waveform data can be directly read for display when the sleep mode is switched. In addition, from the user experience, the ink screen device can also enter the sleep mode from the low-power mode, but the ink screen device actually needs to be restored to the operation mode from the low-power mode, and then is switched to the sleep mode from the operation mode, and the process can be realized by referring to the above. Refreshing screen saver waveform data corresponding to the picture data of the current display picture of the ink screen equipment to the picture data of the screen saver picture in the running process, and updating the picture data to the data buffer subunit at intervals; correspondingly, the controlling the ink screen to display the screen saver picture comprises the following steps: and the screen driving module extracts the screen protection waveform data from the data buffering subunit and drives the ink screen to display according to the screen protection waveform data.
The sleep mode may be entered directly from the running mode, or may be entered from the low power mode, or may be an event occurring over time, or an event detected by the ink screen device when the user actively operates the ink screen device. In order to quickly enter a sleep mode from a low power consumption mode, first screen saver waveform data corresponding to a screen saver picture which is refreshed from a current display picture to the screen saver picture can be stored before the screen saver picture enters the low power consumption mode, the first screen saver waveform data is directly extracted from the data buffering subunit when a sleep switching event is received in the low power consumption mode, the ink screen is driven to display according to the first screen saver waveform data, power supply to the screen driving module is interrupted, the running state of a processor of the ink screen equipment is regulated, and the screen saver enters the sleep mode, so that the speed of entering the screen saver mode is improved. It should be noted that, the process of entering the sleep mode from the low power mode is not limited by the wake-up process of the sleep mode, and the sleep mode may be entered based on the present embodiment only, and the operation mode may be entered from the sleep mode using a conventional manner.
For the sleep mode, only the operation mode can be switched, when the sleep mode is entered, the picture data of the screen saver picture is refreshed to the recovery waveform data corresponding to the picture data displayed currently, and the recovery waveform data is stored in the data buffer subunit; correspondingly, when the sleep mode is switched to the operation mode, the updating the display picture according to the recovery waveform data corresponding to the recovery event comprises the following steps: and the screen driving module extracts the recovery waveform data from the data buffering subunit and drives the ink screen to display according to the recovery waveform data. The whole can also realize the improvement of the picture refreshing speed.
The initialization data of the signal conversion module comprises data configuration of the conversion module, such as confirmation of a transmission format or standard, confirmation of a transmission rate and setting of a transmission mode (such as splicing). After the subsequent screen driving module is powered on again, the screen driving module is reconnected with the signal conversion module, and in order to enable the working mode of the signal conversion module to be matched with the screen driving module, data configuration is required to be carried out on the interface of the signal conversion module and the screen driving module. In general, when the current operation data satisfies the state switching model, the method further includes: storing conversion configuration data to the data buffer subunit, wherein the conversion configuration data comprises a data format, a transmission rate and a transmission mode; correspondingly, the recovering the power supply to the ink screen and updating the display picture according to the target waveform data comprises the following steps: and reading the conversion configuration data from the data buffer subunit, and carrying out data configuration on interfaces of the signal conversion module and the screen driving module according to the read conversion configuration data.
The device running state switching method is used for the ink screen device, and current running data of the ink screen device are obtained when the ink screen device is in a running mode; matching the current operation data with a preset state switching model; when the current operation data meets the state switching model, saving the picture data of the current display picture of the ink screen equipment and the associated picture waveform data, and interrupting the power supply to the ink screen to enter a low-power consumption mode; when a wake-up event is received in the low power consumption mode, confirming target waveform data based on the associated picture waveform data according to a target picture corresponding to the wake-up event and stored picture data; and restoring the power supply to the ink screen and updating a display picture according to the target waveform data. The method actively enters a low-power consumption mode according to the operation parameters of the ink screen, and stores waveform data according to possible page switching when entering the low-power consumption mode, so that the original display picture can be quickly restored without a waveform lookup table, the standby time of the ink screen equipment is improved while the use difference of users is eliminated as much as possible, and the loss of the electronic ink screen is reduced.
