Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In an embodiment, as shown in fig. 1, fig. 1 is a schematic structural diagram of an electronic ink screen device according to an embodiment of the present invention; the present invention provides an electronic ink screen apparatus, which may include: touch screen 10, control module 20, programmable logic device 30, and electronic ink screen 40.
The touch screen 10 is configured to detect an input instruction triggered by a user, and send the input instruction to the control module 20 and the programmable logic device 30.
The control module 20 is configured to receive and determine whether an application scene corresponding to the input instruction belongs to a set scene, and if so, notify the programmable logic device 30 to process the input instruction.
The programmable logic device 30 is configured to process the input instruction after receiving the processing instruction sent by the control module 20, and send the processing result to the electronic ink screen 40.
The electronic ink screen 40 is used for displaying the processing result.
In this embodiment, as shown in fig. 1, the electronic ink screen device may include a touch screen 10, a control module 20, a programmable logic device 30, and an electronic ink screen 40; the touch screen 10 serves as a receiving module of a touch signal, and may send an input instruction triggered by a user to the control module 20 and the programmable logic device 30, where at this time, the programmable logic device 30 does not need to process the input instruction, but waits for the control module 20 to determine whether an application scene corresponding to the input instruction belongs to a setting scene according to the input instruction, and if the application scene belongs to the setting scene, may send a processing instruction to the programmable logic device 30, notify the programmable logic device 30 to process the input instruction in the setting scene, and send a processing result to the electronic ink screen 40 for display.
For the determination of the application scene of the input instruction, the input state, whether the system is in the handwriting optimization mode or the handwriting whiteboard mode, and the like can be detected through a detection mechanism or by using a system component, and the like, or the determination can be performed by actively triggering the handwriting optimization mode by a user, and the like.
It can be understood that the electronic ink screen device provided by the present application may be installed with various different types of system software, such as system software for performing a handwriting drawing operation, and the application may generate corresponding display information, such as handwriting, in response to a handwriting drawing operation triggered by a user on the touch screen 10; the electronic ink screen device provided by the present application further includes system related settings, such as display and brightness, sound, network connection, screen display mode, etc., the user can trigger a brightness adjustment command, or a sound adjustment command, or a network connection command, etc., on the touch screen 10, and the operating system can respond to an input command triggered by the user and adjust the screen brightness, or the sound, or the network connection, etc., according to the input command.
Further, due to the low power consumption characteristic of the electronic ink screen device, a cpu with low power consumption is generally selected, and in this case, if secondary development is required on the touch signal, for example, a simulated handwriting track is constructed according to input parameters, and when the display speed is optimized, the response speed and the overall performance of the system are reduced; the programmable logic device 30 not only can provide strong operational performance, but also can greatly improve the overall comprehensive performance of the electronic ink screen equipment at a low power consumption cost.
Therefore, the present application can process the input commands in some setting scenarios through the programmable logic device 30. Specifically, when the control module 20 determines that the application scenario corresponding to the current input instruction inputs the setting scenario, the control module may send a processing instruction to the programmable logic device 30, and notify the programmable logic device 30 to process the input instruction in the setting scenario, so that not only the resource consumption of the control module 20 can be reduced, but also the response speed and the overall performance of the system can be improved.
It can be understood that, in the present application, an application scenario that needs to respond quickly in the electronic ink screen device may be set as a setting scenario, and when an application scenario corresponding to an input instruction sent by the touch screen 10 to the control module 20 belongs to the setting scenario, the programmable logic device 30 may be notified to process the input instruction. The application scene that needs to be responded quickly may be a handwriting optimization scene, a handwriting whiteboard scene, a gesture shortcut scene, and the like, and the programmable logic device 30 may be configured according to actual conditions, which is not limited herein.
It should be noted that, for the system software, what they can directly access is the control module 20, such as CPU, and the programmable logic device 30 is used as an additional supplementary processing, which functions like a coprocessor, and after connecting the programmable logic device 30, the main work of the control module 20 is still to process the system data of the electronic ink device, such as invoking the corresponding system software according to the input instruction of the user, and providing the computing power and constructing the normal display data through the system software according to the internal logic of the software. However, the difference is that when the application scene corresponding to the input instruction belongs to the setting scene, the control module 20 may call the programmable logic device 30 to perform fast processing on the input instruction and display the input instruction through the electronic ink screen 40, and after the control module 20 constructs normal display data, the previous display data may be corrected, but at this time, related data is already displayed in the electronic ink screen 40, so that the operation does not affect the user experience, and the response speed of the system is also improved.
In the above embodiment, when the touch screen 10 detects an input instruction triggered by a user, the input instruction may be sent to the control module 20 and the programmable logic device 30, and the control module 20 may determine whether an application scene corresponding to the input instruction belongs to a set scene, and if so, notify the programmable logic device 30 to process the input instruction, and send a processing result to the electronic ink screen 40 for display; for example, the programmable logic device 30 can be used for carrying out secondary development on the touch signal, and when the control module 20 judges that the application scene corresponding to the input instruction belongs to a set scene, the programmable logic device 30 can be informed to carry out optimization processing on the input instruction in the set scene, so that not only can the response speed of the input instruction be improved, and the user experience be improved, but also the computing resources of the control module 20 cannot be excessively occupied.
In an embodiment, when the control module 20 determines that the application scene corresponding to the input instruction is a handwriting optimization scene, it notifies the programmable logic device 30 to perform a trajectory construction process on the point data in the input instruction, constructs a first handwriting according to the relevant handwriting parameters of the input instruction, merges the first handwriting and the current screen display data to obtain first display data, and sends the first display data to the electronic ink screen 40.
In this embodiment, the setting scene is generally set to an application scene that requires a quick response, such as a handwriting optimization scene. When the control module 20 determines that the application scene corresponding to the current input instruction is a handwriting optimization scene, the programmable logic device 30 may be notified to process the currently received input instruction, the programmable logic device 30 performs a trajectory construction process on the point data in the input instruction, constructs a first handwriting according to the relevant handwriting parameters of the input instruction, merges the first handwriting and the current screen display data to obtain first display data, and then may display the first display data on the electronic ink screen 40.
Specifically, since a detection mechanism for a handwriting optimization scene is provided in a part of the systems, after receiving an input instruction, the control module 20 may first determine whether a detection mechanism exists in the current system, and if so, may invoke a corresponding detection mechanism to detect whether the current input instruction belongs to the input instruction in the handwriting optimization scene; if not, the current system component and the input state can be detected to determine whether the system component is in the handwriting optimization scene or not, or the historical behavior track of the user is checked, and whether the user actively triggers to enter the handwriting optimization scene or not is judged.
When control module 20 determines that the application scenario corresponding to the current input instruction is the handwriting optimization scenario, programmable logic device 30 may be notified to process the input instruction. Furthermore, the handwriting optimization scene refers to an application scene for optimizing the handwriting display effect on the premise of not needing third-party software adaptation as the fitting handwriting is constructed by inputting instructions. Therefore, when the programmable logic device 30 constructs a fitting handwriting, the control module 20 needs to issue relevant handwriting parameters, where the relevant handwriting parameters may be parameters set by the user in a handwriting optimization scene in advance, or may be default handwriting optimization parameters of the system. After the programmable logic device 30 obtains the relevant handwriting parameters and the input instruction, the relevant handwriting parameters may be used to fit the point data in the input instruction.
It can be understood that in the handwriting optimization scene, the input instruction sent by the user generally includes point data in the handwriting optimization scene, and after the programmable logic device 30 obtains the point data, the point data may be fitted according to the relevant handwriting parameters to construct a first handwriting, for example, color, direction, and the like of the point data are optimized, so that the first display data finally presented on the electronic ink screen 40 is the data required by the user.
In one embodiment, the control module 20 constructs a second handwriting according to the input instruction and the relevant handwriting parameter, obtains second display data, and sends the second display data to the programmable logic device 30.
The programmable logic device 30 synthesizes the first display data and the second display data to obtain a synthesis result, and sends the synthesis result to the electronic ink screen 40.
In this embodiment, in a handwriting optimization scenario, the control module 20 informs the programmable logic device 30 to perform fast fitting on the point data in the input instruction to obtain the first display data, and since the display speed of the first display data is fast, the user's requirement can be responded fast, and the user's experience is improved. However, the part of the programmable logic device 30 is only responsible for fitting the handwriting, and the programmable logic device 30 does not calculate whether the fitting handwriting should be displayed or not and the occlusion relationship between the fitting handwriting and the front and back layers.
Therefore, in order to display a truly accurate result on the basis of quickly responding to a user, the control module 20 can be used for combining the operation logic and the relevant handwriting parameters in the system to operate the point data in the input instruction to obtain second display data, the second display data is sent to the programmable logic device 30 to be synthesized with the first display data, and finally the synthesized result is displayed on the electronic ink screen 40.
In one embodiment, when determining that the application scene corresponding to the input instruction is a handwritten whiteboard scene, the control module 20 notifies the programmable logic device 30 to process the input instruction.
The programmable logic device 30 generates third display data according to the handwriting trace in the input instruction, and sends the third display data to the electronic ink screen 40.
In this embodiment, when the control module 20 determines that the application scene corresponding to the input instruction is a handwritten whiteboard scene, it may notify the programmable logic device 30 to process a handwritten trajectory in the input instruction, generate third display data according to the handwritten trajectory, send the third display data to the electronic ink screen 40, and then display the third display data through the electronic ink screen 40.
It can be understood that the handwritten whiteboard scene is an application scene mainly used for circling any position of an interface or making handwritten annotations according to real-time input data of a user, in the application scene, the control module 20 can send an instruction to activate the programmable logic device 30, and the programmable logic device 30 can directly generate and display third display data according to a handwritten track in the input instruction without system software adaptation, so that the purpose of quick response is achieved.
In one embodiment, when determining that the application scene corresponding to the input instruction is a gesture shortcut scene, the control module 20 notifies the programmable logic device 30 to process the input instruction.
The programmable logic device 30 generates a shortcut instruction according to the gesture information in the input instruction, and sends the shortcut instruction to the electronic ink screen 40.
And the electronic ink screen 40 adjusts the display data according to the shortcut instruction.
In this embodiment, when the control module 20 determines that the application scene corresponding to the input instruction is the gesture shortcut scene, it may notify the programmable logic device 30 to generate a shortcut instruction according to gesture information in the input instruction, and send the shortcut instruction to the electronic ink screen 40, so that the electronic ink screen 40 adjusts display data displayed on the electronic ink screen 40 according to the shortcut instruction.
Specifically, when the control module 20 determines that the application scene corresponding to the input instruction is the gesture shortcut scene, the programmable logic device 30 may process gesture information in the current input instruction. For example, in the case of a non-handwriting optimized scenario, the programmable logic device 30 may perform a shortcut command adjustment on the image according to the gesture information in the input command, such as by processing the currently acquired display data, performing an overall contrast/sharpness/brightness increase or decrease operation on the display data, and so on.
In the application scenario, the programmable logic device 30 may quickly respond to gesture information input by a user, such as increasing or decreasing the brightness of a desktop, and increasing or decreasing a sound, so as to further increase the response speed of the display data.
In one embodiment, the control module 20 may include a central processor.
The programmable logic device 30 may comprise one or more of a CPLD, an FPGA, or a combination of application specific integrated circuits.
In this embodiment, the control module 20 may select a central processing unit to implement the control and processing operations of the present application, and the programmable logic device 30 may select one or more of a CPLD, an FPGA, and an asic to implement the fast response operations of the present application.
It will be appreciated that the present application preferably implements the fast response operation of the present application using FPGAs, most of which contain high-level built-in modules (such as adders and multipliers) and built-in memory, so that the FPGAs support full or partial intra-system reconfiguration, allowing their design to change as the system is upgraded or dynamically reconfigured. Some FPGAs allow a portion of the device to be re-edited while other portions continue to operate normally. In the actual production environment of the electronic ink screen equipment, the programmable logic device 30 with high editing flexibility is adopted, the subsequent plasticity is high, and the continuous optimization upgrading of the software level of the electronic ink screen equipment in the actual production environment can be met, and the requirement change of different conditions can be met.
In an embodiment, as shown in fig. 2, fig. 2 is a schematic flow chart of a display method of an electronic ink screen according to an embodiment of the present invention; the invention also provides a display method of the electronic ink screen, which is applied to electronic ink screen equipment, wherein the equipment comprises a control module 20 and a programmable logic device 30, and the method comprises the following steps:
s110: the control module 20 receives an input command triggered by a user.
S120: when the control module 20 determines that the application scene corresponding to the input instruction belongs to the setting scene, it notifies the programmable logic device 30 to process the input instruction, and transmits the processing result to the electronic ink screen 40 for display through the programmable logic device 30.
In the above embodiment, after the control module 20 receives an input instruction triggered by a user, the control module 20 may determine whether an application scene corresponding to the input instruction belongs to a set scene, and if so, may notify the programmable logic device 30 to process the input instruction, and transmit a processing result to the electronic ink screen 40 for display; because the programmable logic device 30 can provide powerful operation performance, and can also greatly improve the overall comprehensive performance of the electronic ink screen device with lower power consumption cost, for example, the programmable logic device 30 can be used to perform secondary development on a touch signal in the application, and when the control module 20 determines that the application scene corresponding to the input instruction belongs to a set scene, the control module can inform the programmable logic device 30 to perform optimization processing on the input instruction in the set scene, so that not only can the response speed of the input instruction be improved, but also the user experience is improved, and the computing resources of the control module 20 cannot be excessively occupied.
In one embodiment, in S120, when the setting scene is a handwriting optimization scene, the notifying, by the control module 20, the programmable logic device 30 to process the input instruction may include:
s121: the control module 20 sends the relevant handwriting parameters corresponding to the input instruction to the programmable logic device 30, and the programmable logic device 30 constructs a first handwriting corresponding to the point data in the input instruction according to the relevant handwriting parameters, and converts the first handwriting into first display data.
In this embodiment, when the control module 20 determines that the application scenario corresponding to the current input instruction is the handwriting optimization scenario, since the programmable logic device 30 also receives the input instruction synchronously, the control module 20 may notify the programmable logic device 30 to process the input instruction. Further, the handwriting optimization scene refers to an application scene for optimizing the handwriting display effect on the premise of not needing third-party software adaptation because the first handwriting is constructed by inputting instructions. Therefore, when the programmable logic device 30 constructs the fitting handwriting, the control module 20 may issue relevant handwriting parameters, where the relevant handwriting parameters may be parameters set by the user in the handwriting optimization scene in advance, or may be default handwriting optimization parameters. After the programmable logic device 30 obtains the relevant handwriting parameters and the input instruction, the relevant handwriting parameters may be used to construct a first handwriting corresponding to the point data in the input instruction.
In one embodiment, the method may further comprise:
s122: and the control module 20 constructs a second handwriting corresponding to the point data in the input instruction according to the relevant handwriting parameters, and converts the second handwriting into second display data.
S123: the control module 20 sends the second display data to the programmable logic device 30, and the programmable logic device 30 synthesizes the first display data and the second display data to obtain a synthesis result.
In this embodiment, in a handwriting optimization scenario, the control module 20 calls the programmable logic device 30 to perform fast fitting on the point data in the input instruction to obtain the first display data, and since the display speed of the first display data is fast, the user's requirement can be responded fast, and the user's experience is improved. However, the portion of programmable logic device 30 is responsible only for fitting the writing, and programmable logic device 30 does not calculate whether the fitting writing should be displayed for that segment, and the occlusion relationship of the fitting writing to the front and back layers.
Therefore, in order to display a truly accurate result on the basis of quickly responding to a user, the control module 20 can be combined with the operation logic and the relevant handwriting parameters in the system to operate the point data in the input instruction to obtain second display data, the second display data is sent to the programmable logic device 30 to be synthesized with the first display data, and finally the synthesized result is displayed on the electronic ink screen 40.

s210: programmable logic device 30 receives an input command triggered by a user;
s220: after receiving the processing instruction sent by the control module 20, the programmable logic device 30 processes the input instruction to obtain a processing result;
s230: programmable logic device 30 sends the results of the processing to electronic ink screen 40 for display.
In the above embodiment, the programmable logic device 30 may receive an input instruction triggered by a user, process the input instruction after receiving a processing instruction sent by the control module 20, and send a processing result to the electronic ink screen 40 for display; for example, the programmable logic device 30 can be used for carrying out secondary development on the touch signal, and when the control module 20 judges that the application scene corresponding to the input instruction belongs to a set scene, the programmable logic device 30 can be informed to carry out optimization processing on the input instruction in the set scene, so that not only can the response speed of the input instruction be improved, and the user experience be improved, but also the computing resources of the control module 20 cannot be excessively occupied.
