The second input characteristic information here includes touch position information of the second touch input.

By the structure of the display device, a user can watch the content written on each part in the display device through the touch display screen 110, so that the user can watch the display device conveniently, and the display effect of the display device is enriched.

In consideration of cost performance, a double-side dense-lamp infrared touch scheme is often adopted in the related art, as shown in fig. 2, fig. 2 is a schematic diagram of a double-side dense-lamp infrared touch scheme shown in the related art, in the scheme, infrared grids on the left side and the right side of the touch display screen 110 are sparse due to the fact that infrared touch components are not arranged on the left side and the right side, and situations such as pen loss, pen jumping, line breaking during writing on the edge of the touch display screen 110 may occur. In order to make up for this drawback, manufacturers generally extend an extra section of infrared touch components, that is, the widths of the black edges at two sides of the display area of the touch display screen 110 are increased, so that the display area located at the inner side of the black edge has more dense infrared rays, and the situation of line missing and line breaking at the edge of the display area is reduced, but this way increases the volume of the touch display screen 110 and affects the appearance. It should be noted that the black border is a part of the touch screen display, and is integrated with the middle display area.

Based on this, in some embodiments, the first touch detection component includes a first infrared touch component disposed on at least one set of opposite borders of the writing panel 120, and the first infrared touch component covers at least a portion of edges of the at least one set of opposite borders of the writing panel 120;

the second touch detection assembly includes a second infrared touch assembly disposed on at least one set of opposite frames of the touch display screen 110.

In this embodiment, on the touch display screen 110 and the writing panel 120, infrared touch components are respectively disposed, on one hand, both the touch display screen 110 and the writing panel 120 can achieve the effect of touch writing, and on the other hand, because infrared touch components are also disposed on the handwriting board at the side of the touch display screen 110, the edge of the touch display screen 110 also has dense infrared rays, thereby avoiding situations such as pen loss, pen skip, line break writing, line break by multi-stroke line break at the edge of the touch display screen 110 as much as possible, and therefore, the touch display screen 110 in this embodiment can narrow the width of the black edge, thereby reducing the volume of the touch display screen 110, and improving the aesthetic measure of the touch display screen 110.

Optionally, when the infrared touch components are disposed on the writing panel 120 and the touch display screen 110, the infrared grids formed by the first infrared touch component and the second infrared touch component can be integrated into a whole, and the first infrared touch component and the second infrared touch component can be disposed on the upper and lower frames.

The infrared touch control assembly has the working principle that infrared rays are emitted through the infrared emitting tubes, the corresponding infrared receiving tubes receive the infrared rays, an infrared grid can be formed through the plurality of infrared emitting tubes and the plurality of infrared receiving tubes which are sequentially arranged, in the writing process, a user finger or chalk and the like can contact the infrared rays, the position where the infrared rays are touched is a touch control position, the touch control track is confirmed according to the touch control position, and input contents corresponding to the touch control track can be obtained.

Based on this, if the first infrared touch device and the second infrared touch device are both disposed on the upper and lower frames, referring to fig. 3, fig. 3 is a schematic view illustrating an arrangement of the infrared touch devices according to an exemplary embodiment. Then can set up a plurality of infrared transmitting tubes at the interval on last frame, set up a plurality of infrared receiving tubes at the interval on lower frame, infrared transmitting tube and infrared receiving tube's quantity and position are all one-to-one. Of course, the infrared transmitting tube may be disposed on the lower frame, and the infrared receiving tube may be disposed on the upper frame, which is not limited in this disclosure.

Optionally, because the touch display screen 110 is adjacent to the two writing panels 120, a set of infrared touch components may also be disposed on the left frame of the left writing panel 120 and the right frame of the right writing panel 120, for example, a plurality of infrared transmitting tubes are disposed on the left frame of the left writing panel 120, and a plurality of infrared receiving tubes are disposed on the right frame, that is, a four-sided infrared touch frame is formed, so as to further increase the density of infrared grids on the display device, and increase the accuracy and precision of touch recognition.

Optionally, the infrared transmitting tube may be an infrared lamp bead, and the infrared lamp beads are sequentially arranged on the lamp panel to form an infrared lamp strip. The infrared receiving tube may be a photosensor, which is also sequentially disposed on the substrate.

In other embodiments, the infrared grid formed by the first infrared touch device covers the entire writing panel 120, and the area of the minimum mesh of the infrared grid is smaller than the first predetermined area.

In this embodiment, the first infrared touch component may completely cover the entire edge of at least one set of opposite borders of the writing panel 120, for example, as shown in fig. 3, the first infrared touch component may completely cover the upper and lower borders of the writing panel 120; alternatively, the first infrared touch component may cover partial edges of at least one set of opposite borders, for example, as shown in fig. 4, where fig. 4 is another infrared touch component arrangement diagram according to an exemplary embodiment. The first infrared touch assembly may cover only 3/4 of the upper and lower borders of the writing panel 120. That is, the coverage ratio of the first infrared touch device to the frame of the writing panel 120 depends on the coverage area of the formed infrared grid. No matter which implementation manner is adopted, it is required to ensure that the infrared grid formed by the first infrared touch component can cover the whole writing panel 120 area, and in this case, it can be ensured that the whole writing panel 120 area can be subjected to touch input.

The first predetermined area is a cross-sectional area of the writing tool on the writing panel 120, and for example, if the writing tool on the writing panel 120 is chalk, the first predetermined area is a cross-sectional area of the chalk, an area of a minimum mesh of the infrared mesh is required to be smaller than the cross-sectional area of the chalk, the area of the minimum mesh of the infrared mesh depends on an installation density of the infrared beads, and the area of the minimum mesh is smaller as the density is larger. Under the condition, the track of the chalk can be accurately identified only when the chalk is used for writing, the conditions of line breakage and line leakage are avoided, and the touch identification precision is ensured. That is, the touch recognition accuracy of the writing panel 120 depends on the setting density of the infrared lamp beads in the first infrared touch component.

Similarly, in order to ensure the recognition accuracy of the touch display screen 110 and avoid the occurrence of line breakage and line leakage, the setting density of the infrared lamp beads in the second infrared touch component also depends on the area of the minimum mesh of the infrared grid formed on the touch display screen 110, and since the touch display screen 110 is usually written by a finger or a stylus, the area of the minimum mesh of the infrared grid needs to be smaller than the sectional area of the finger or the stylus.

Optionally, the writing panels 120 are respectively disposed on two sides of the touch display screen 110, and the setting density of the infrared lamp beads in the second infrared touch component may be the same as the setting density of the infrared lamp beads in the first infrared touch component. In this case, since the touch display screen 110 is located between the two writing panels 120, and the infrared receiving tube in the second infrared touch component can also receive the infrared rays emitted from the first infrared touch component, the infrared grids on the touch display screen 110 are dense, and can support fine writing without error, while the infrared grids at the edge portions of the left and right writing panels 120 are sparse, and the sectional area of a general writing tool is large, for example, the diameter of the writing tool on the writing panel 120 is greater than 8mm, so that it is ensured that no pen is lost or broken. In this case, writing can be performed with a thin pen on the middle touch display screen 110, and writing can be performed with a thick chalk or the like on the both writing panels 120. Of course, the above is only an example, the setting density of the infrared lamp beads in the second infrared touch component may also be different from the setting density of the infrared lamp beads in the first infrared touch component, for example, the setting density of the infrared lamp beads in the first infrared touch component is greater than that of the second infrared touch component, which is not limited in this disclosure.

In other embodiments, as shown in fig. 3, the first touch detection device and the second touch detection device may be an integrated structure. That is, the infrared lamp strip in the first touch detection assembly and the infrared lamp strip in the second touch detection assembly can be of an integral structure, or the infrared lamp bead in the first touch detection assembly and the infrared lamp bead in the second touch detection assembly are arranged on the same substrate; the infrared receiving tube in the first touch detection assembly and the infrared receiving tube in the second touch detection assembly are arranged on the same substrate. Under the condition, the first touch detection assembly and the second touch detection assembly can be located on the same horizontal line as far as possible, so that the edges of the formed infrared grid are relatively neat, the deformation is relatively small, and the accuracy of touch detection is improved.

In still other embodiments, as shown in fig. 5, fig. 5 is a schematic diagram illustrating an infrared touch device with a split structure according to an exemplary embodiment. The first touch detection assembly and the second touch detection assembly can be of a split structure. Namely, the first touch detection assembly and the second touch detection assembly are three independent structures. The infrared lamp strip in the first touch detection assembly and the infrared lamp strip in the second touch detection assembly are of independent structures respectively, and the infrared receiving tube in the first touch detection assembly and the infrared receiving tube in the second touch detection assembly are not arranged on the same substrate. Under the condition, when a fault occurs in the subsequent touch detection assembly, the maintenance of workers is facilitated, and the touch detection assemblies with the faults can be maintained while other parts of the touch detection assemblies can work normally, so that the reliability of the display equipment is improved.

In this embodiment of the disclosure, after recognizing the input trajectory of the user in the writing panel 120, in order to ensure that the input trajectory on the writing panel 120 can be displayed at the same position on the touch display screen 110, the processor 130 needs to determine the coordinate of the input trajectory on the writing panel 120 and convert the coordinate into the rectangular coordinate system of the touch display screen 110, where an origin of the rectangular coordinate system corresponding to the writing panel 120 may be a boundary point of the writing panel 120, for example, a lower left corner boundary point of the display device may be an origin of the rectangular coordinate system corresponding to the writing panel 120, and an origin of the rectangular coordinate system corresponding to the touch display screen 110 is a boundary point of the touch display screen 110.

Based on this, in some embodiments, the sum of the areas of the two writing panels 120 may be equal to the area of the touch display screen 110. In this case, when the coordinate conversion is performed, the coordinates of the input trajectory on the writing panel 120 can be directly added or subtracted, that is, converted into the rectangular coordinate system corresponding to the touch display screen 110, without scaling the coordinates, and the like, so that the coordinate conversion process is simplified, and the touch display efficiency is improved. Alternatively, if the heights of the writing panels 120 and the touch display screen 110 are the same, it may be limited that the sum of the widths of the two writing panels 120 may be equal to the width of the touch display screen 110.

In one or more embodiments, the writing panel 120 and the touch display screen 110 may be fixedly connected, that is, neither the writing panel 120 nor the touch display screen 110 is movable. Alternatively, the writing panel 120 may be a push-pull type structure, i.e., the writing panel 120 can move along a horizontal track in a horizontal direction. When the two writing panels 120 move toward the middle, the two writing panels 120 block the front of the touch display screen 110.

In the case that the processor 130 is disposed on the touch display screen 110, since the first touch detection component on the writing panel 120 needs to send the first input feature information to the processor 130, there needs to be an electrical connection between the writing panel 120 and the touch display screen 110. Based on this, optionally, a spring probe is disposed on one side of the writing panel 120, which is in contact with the touch display screen 110, and probe points are disposed on two sides of the touch display screen 110 and at positions corresponding to the spring probe respectively; the spring probe is conducted after being contacted with the probe point; when the two writing panels 120 move to the position of contact, the two spring probes disposed on the two writing panels 120 are in contact conduction.

That is, in the present embodiment, the connection between the two writing panels 120 and the middle touch display screen 110 is through a spring probe, referring to fig. 6, fig. 6 is a schematic diagram illustrating a push-pull type display device according to an exemplary embodiment. When the left and right writing panels 120 are pushed to the middle region, the left and right writing panels 120 may be coupled together again by a spring probe, as shown in fig. 7, and fig. 7 is a schematic view illustrating a push-pull type display device according to another exemplary embodiment. In this case, the user can move the writing panel 120 according to his or her needs, for example, in the case of not touching the display screen 110, the writing panel 120 can be moved in the manner of fig. 7. The use mode of the display device is enriched.

Since the two writing panels 120 can be pushed and pulled to the middle position in the above embodiment, when the heights of the two writing panels 120 are the same as the height of the touch display screen 110 and the sum of the widths of the two writing panels 120 is equal to the width of the touch display screen 110, as shown in fig. 8, fig. 8 is a schematic size diagram of a display device according to an exemplary embodiment. In the state of fig. 7, two writing panels 120 exactly cover the touch display screen 110, and at this time, coordinate conversion is not needed to display the input content on the writing panels 120 on the touch display screen 110; if the sum of the areas of the two writing panels 120 is not equal to the area of the touch display screen 110, then coordinate conversion is required to display the input content on the writing panels 120 on the touch display screen 110.

In still other embodiments, the display device may further include a memory for storing a program or instructions, and the processor 130 may implement the functions by executing the program or instructions. Further, the memory may be further operable to: the first input content or the second input content is stored based on a control instruction of the processor 130.

In this embodiment, the display device can store the input content in the writing panel 120 or the touch display screen 110, so that the user can subsequently view the historical input content and can also invoke the historical input content to be displayed. The use modes of the display device are enriched, and the convenience of a user is improved.

The memory may be implemented by any type or combination of volatile or non-volatile memory devices, such as Static Random Access Memory (SRAM), electrically erasable programmable read-only memory (EEPROM), erasable programmable read-only memory (EPROM), programmable read-only memory (PROM), read-only memory (ROM), magnetic memory, flash memory, magnetic or optical disks.

In addition, to ensure the above-described functionality in the display device, each component in the display device needs to be connected to a power supply, which may include a power management system, one or more power supplies, and other components associated with generating, managing, and distributing power for the display device.

Based on the display device provided in the above embodiments, an embodiment of the present disclosure further provides an information display method, and fig. 9 is a flowchart illustrating an information display method according to an exemplary embodiment, as shown in fig. 9, the method includes the following steps.

S210, receiving a first touch input of a user on a writing panel.

The first touch input may be input by a finger, a stylus, or the like, in which the first touch detection component can detect the first touch input, but the writing panel has no writing trace, that is, the user cannot see the writing content on the writing panel with naked eyes. Alternatively, the first touch input may be writing input on the writing panel by an entity pen such as chalk or a marker pen, and in the writing process, since the entity pen is also in contact with and moves along the writing panel, not only the first touch detection module can detect the first touch input, but also a writing trace exists on the writing panel, and a user can see the writing content on the writing panel by naked eyes.

S220, identify a touch trajectory of the first touch input, and obtain first input content corresponding to the first touch input.

In order to determine the first input content corresponding to the first touch input, a position coordinate set of a touch point of the first touch input needs to be identified, and a touch trajectory of the first touch input is determined according to the position coordinate set. Subsequently, the touch track can be directly used as first input content, the original proportion of the touch track is reduced to the touch display screen for display, and the content on the writing panel is mainly written manually, so that the recognition process can be simplified by directly displaying the touch track, and the complete and accurate display of the written content is ensured.

And S230, under the condition that the display device is in the first mode, displaying the first input content on the touch display screen.

Here, the first mode is a sub-page mode, in which the touch display screen directly displays the input content of the user on the writing panel. Optionally, in order to avoid collision between the input content on the writing panel and the input content on the touch display screen and ensure that the input content in the writing panel can be imaged on the touch display screen in the original size and writing position, in the first mode, the input content in the touch display screen of the user may not be displayed, but only the input content in the writing panel is displayed.

Optionally, the manner of controlling the display device to enter the first mode may include: and controlling the display device to enter the first mode in response to the received triggering input of the first mode control by the user. Or, if the current display device is in the second mode, the display device may be controlled to be switched from the second mode to the first mode in response to a received user trigger input to the mode switching control. The second mode will be described later herein. Specifically, which way to enter the first mode is adopted, and the disclosure is not limited.

In the embodiment of the disclosure, a writing panel on a side of a touch display screen in a display device can receive a first touch input, and send first input characteristic information of the first touch input to a processor for trajectory recognition, a subsequent processor can recognize first input content corresponding to the first input characteristic information, and display the first input content on the touch display screen, and the touch display screen can also display the touch input content received by the touch display screen. The structure of the display device enables a user to watch the content written on each part in the display device through the touch display screen, facilitates the watching of the user on the display device, and enriches the display effect of the display device.

In other embodiments, referring to FIG. 10, FIG. 10 is a flow chart illustrating another method of displaying information according to an exemplary embodiment. The above method may further comprise:

s240, receiving a second touch input of the user on the touch display screen.

The second touch input may be input by a finger, a stylus, or the like, in which the second touch detection component can detect the second touch input, but no physical writing trace is on the touch display screen.

S250, identifying a touch trajectory of the second touch input to obtain a second input content corresponding to the second touch input.

In order to determine second input content corresponding to the second touch input, a position coordinate set of a touch point of the second touch input needs to be identified, and a touch trajectory of the second touch input is determined according to the position coordinate set. Subsequently, the touch trajectory can be directly used as second input content, the original proportion of the touch trajectory is reduced to the touch display screen for displaying, and the second touch input content is manually written, so that the recognition process can be simplified by directly displaying the touch trajectory, and the complete and accurate display of the written content is ensured.

And S260, displaying second input content on the touch display screen under the condition that the display equipment is in the second mode.

Here, the second mode is a home mode, in which the touch display screen directly displays the input content of the user on the touch display screen. In the second mode, the user's input content in the writing panel may not be displayed, but only the input content in the touch display screen.

Wherein, there is no restriction on the sequence between S210-S230 and S240-S260.

Optionally, the manner of controlling the display device to enter the second mode may include: and controlling the display device to enter the second mode in response to the received user trigger input to the second mode control. Or, if the current display device is in the first mode, the display device may be controlled to be switched from the first mode to the second mode in response to a received user trigger input to the mode switching control. Specifically, which way to enter the second mode is adopted, and the disclosure is not limited.

In this embodiment, a user can perform touch input on the touch display screen, and when the display device is in the second mode, input content of the touch input can be displayed on the touch display screen. Under the condition, the user can adjust the source of the content displayed on the touch display screen only by adjusting the mode of the display device in the process of using the display device, so that the user can watch the content written on each part in the display device through the touch display screen, and the user can watch the display device conveniently. Moreover, the content displayed on the touch display screen is distinguished through the second mode and the first mode, the conflict between the content written on the touch display screen and the content written on the writing panel during display can be avoided, the touch display screen can be guaranteed to display the written content through the original size as far as possible, and the display effect is better.

In some embodiments, a target application software may be provided within the display device, the target application software being capable of detecting whether the location of the touch input is a writing pad or a touch display screen. For example, when the first touch input or the second touch input is received, the coordinates corresponding to the first touch input or the second touch input are the coordinates in the same rectangular coordinate system, in this case, the target application software can determine the position of the touch input according to the coordinates corresponding to the touch input, for example, assuming that the coordinate corresponding to the touch input is X, the widths of the two writing panels are both a, the width of the touch display screen is b, the heights of the two writing panels and the touch display screen are the same, the lower left corner of the left writing panel is taken as the origin of the rectangular coordinate system, then when 0< X < a, it means that the touch input is the first touch input in the left writing panel, when a < X < b, the touch input is represented as a second touch input in the touch display screen, and when b < X < c, the touch input is represented as a first touch input in the right writing panel.

After determining the position of the touch input, the target application software may further detect whether the current mode of the display device is the first mode or the second mode, and based on the position of the touch input and the mode of the display device, the target application software may control the content displayed in the touch display screen. For example, after receiving the touch input, the target application software determines that the touch input is a first touch input in the writing panel according to the coordinates of the touch input, and then detects whether the target application software is currently in the first mode, if the target application software is in the first mode, the target application software controls the touch display screen to display first input content of the first touch input, and if the target application software is in the second mode, the target application software does not display the first input content.

Or, in the foregoing embodiment, it is determined whether the position of the touch input is the writing panel or the touch display screen according to the coordinates, or the determination may be performed by the processor, that is, after the processor determines the interval range where the coordinates of the received touch input are located, the processor uploads the protocol flag bit corresponding to the interval range where the coordinates are located to the target application software, for example, the first writing panel corresponds to the first sub-page flag bit, the second writing panel corresponds to the second sub-page flag bit, and the touch display screen corresponds to the main page flag bit. And the target application software determines the position of the touch input according to the content of the zone bit.

In other embodiments, the target application software may also detect whether the position of the touch input is the writing panel or the touch display screen without based on the coordinates of the touch input, for example, when the first touch detection component and the second touch detection component send the input feature information corresponding to the touch input, the first touch detection component and the second touch detection component may carry the component identifier of the touch detection component, and the target application software may determine whether the position of the touch input is the writing panel or the touch display screen according to the component identifier of the touch input. The target application software may also detect the position of the touch input in other ways, which is not limited by this disclosure.

In addition, optionally, in the foregoing embodiment, the target application software first detects the position of the touch input, and then determines the mode of the current display device, which is only a specific example. In other embodiments, the target application software may also first detect the mode of the current display device, and then determine the position of the touch input. Alternatively, the target application software may also perform the detection of the position of the touch input and the detection of the mode of the display device in parallel using different processes. The present disclosure is not limited to specific methods.

In addition, in the foregoing embodiment, in order to facilitate the target application software to determine the position of the touch input, the coordinates corresponding to the first touch input or the second touch input are the coordinates in the same rectangular coordinate system, but when the touch display screen is displaying, the display position is determined based on the rectangular coordinate system in which the self boundary point is the origin, and therefore, in this case, if the first input content or the second input content is to be displayed in the touch display screen, coordinate conversion is required.

Based on this, in some embodiments, the above S230 may include:

s2301, in a case that the first touch input is a touch input to the second writing panel, converting a first position coordinate corresponding to the first touch input in the first rectangular coordinate system into a second position coordinate corresponding to the second rectangular coordinate system.

The first writing panel and the second writing panel are located on different sides of the touch display screen, the origin of the first rectangular coordinate system is a first boundary point, far away from the touch display screen, on the first writing panel, and the origin of the second rectangular coordinate system is a second boundary point, closest to the first boundary point, on the touch display screen. For example, the first writing panel is a writing panel on the left side of the touch display screen, the first boundary point is a boundary point on the lower left corner of the first writing panel, and the second boundary point is a boundary point on the lower left corner of the touch display screen.

Since the first rectangular coordinate system uses the first boundary point of the first writing panel far from the touch display screen as the origin, if the touch input is the first touch input in the first writing panel, the value of the coordinate is not changed after the first position coordinate corresponding to the first touch input in the first rectangular coordinate system is converted into the second position coordinate corresponding to the second rectangular coordinate system. That is, assuming that the first position coordinate is X1, after converting X1 to the second rectangular coordinate system, the second position coordinate X1' is X1.

If the touch input is the first touch input in the second writing panel, assuming that the first position coordinate is X2, the widths of the first writing panel and the second writing panel are both a, the width of the touch display screen is b, and the heights of the two writing panels and the touch display screen are the same, after converting X2 to the second rectangular coordinate system, the second position coordinate X2 ═ X2- (a + b) + a ═ X2-b.

S2303, displaying the first input content at the second position coordinate of the touch display screen.

Accordingly, the S260 may include:

s2601, converting a third position coordinate of the second touch input in the first rectangular coordinate system into a fourth position coordinate of the second rectangular coordinate system.

If the touch input is the second touch input in the touch display screen, assuming that the third position coordinate is X3, the widths of the first writing panel and the second writing panel are both a, the width of the touch display screen is b, and the heights of the two writing panels and the touch display screen are the same, after converting X3 into the second rectangular coordinate system, the fourth position coordinate X3' is X3-a.

In the above, for the case that the sum of the areas of the two writing panels is equal to the area of the touch display screen, if the sum of the widths of the two writing panels is not equal to the width of the touch display screen, it indicates that the two writing panels cannot exactly cover the touch display screen after being spliced together, and therefore, in this case, when the input content in the two writing panels is displayed in the touch display screen, in order to ensure that the input content can have the same display effect as that in the writing panels as much as possible, the change of the position coordinates may further include an equal-scale increase, an equal-scale decrease or other translation operations. How to realize the coordinate transformation is related to the sizes of the writing panel and the touch display screen, which is not limited in the present disclosure.

S2603, displaying the second input content at the fourth position coordinate of the touch display screen.

In this embodiment, a first rectangular coordinate system is constructed with a first boundary point of the first writing surface, which is far away from the touch display screen, as an origin, and initial coordinates of the first touch input and the second touch input are both coordinates in the first rectangular coordinate system. After the target application software determines the position of the touch input based on the initial coordinates, the initial coordinates of the first touch input and the second touch input need to be converted from the first rectangular coordinate system to coordinates in the second rectangular coordinate system. Therefore, when the input content in the writing panel is displayed in the touch display screen, the input content can be displayed according to the same size and input position, and the viewing effect of a user is facilitated.

In addition, under the condition that the sum of the areas of the writing panels on the two sides is equal to the area of the touch display screen, if the writing blackboards on the two sides contain touch input, coordinates corresponding to the touch input in the writing blackboards on the two sides can be converted and combined, and the two parts of coordinates are combined into a whole complete coordinate and then reported to target application software for display. By the mode, when the content of the writing panels is displayed on the touch display screen, the content of the writing panels on the two sides can be displayed simultaneously, and a user can conveniently check the content of the writing panels on the two sides.

Optionally, when the writing panels in the display device are push-pull type and the sum of the areas of the two writing panels is equal to the area of the touch display screen, the two writing panels are pushed to the middle area to completely cover the touch display screen, and then the rectangular coordinate systems formed on the two writing blackboards are overlapped with the rectangular coordinate system formed on the touch display screen, so that coordinate conversion is not required.

In addition, in the above case, since the touch display screen is completely shielded, the touch function of the touch display screen can be shielded at this time. Therefore, the power consumption of the touch display screen is reduced.

In other embodiments of the present disclosure, the method may further include at least one of:

in response to a first save input to the first save control, saving first input content;

in response to a second save input to the second save control, save the second input content.

The two writing panels may correspond to the same first saving control, that is, after the user triggers the first saving control, the contents in the two writing panels are saved at the same time, for example, the contents in the two writing panels are integrated into one page for saving; or each writing panel may correspond to one first saving control individually, that is, after the user triggers the first saving control, only the content in the writing panel on the side corresponding to the first saving control is saved. Or, the first saving control and the second saving control may correspond to the same function key, and the user may save the first input content or the second input content through different input modes, for example, clicking a saving function key, saving the content of the writing panel, pressing the saving function key for a long time, and saving the content of the touch display screen. The present disclosure is not limited to specific methods.

In addition, the first saving control and the second saving control are disposed in a fixed area on the display device, and may be implemented in the form of a soft switch (e.g., a touch screen button) or a hard switch (e.g., a physical button).

In this embodiment, the user can save the input content in the writing panel or the touch display screen by triggering the first saving control or the second saving control. Therefore, in the first mode, when the touch display screen cannot display the second input content, the user can select to store the second input content, and in the second mode, when the touch display screen cannot display the first input content, the user can select to store the first input content, so that the subsequent user can conveniently call the stored content to check and learn. In addition, the storage mode manually controlled by the user can avoid occupation of storage space by excessive invalid data, and storage efficiency is improved.

In other embodiments, since the input content is mainly recognized through the touch trajectory in the present disclosure, at the time when the first save input or the second save input is received, only the touch trajectory at the time can be recognized, which results in that the above-mentioned purpose of saving cannot be achieved. Based on this, in the first mode, as for the first input content, the processor already acquires the first input content, the first input content can be directly acquired from the buffer of the processor for saving, and the same is true for the second input content in the second mode. For the second input content in the first mode and the first input content in the second mode, the second input content and the first input content may be temporarily stored in a preset buffer area, if the storage input is not received or an erasing input for the contents is received within a preset time (for example, 30s), the part of the contents may be deleted, and if the erasing input is not received and the storage input is received within the preset time, the buffered input content may be stored.

In addition, in other embodiments, in the first mode, the second input content may also be automatically saved, where whether the first input content is saved depends on whether the first saving input is received; in the second mode, the first input content may be automatically saved, where whether the second input content is saved depends on whether a second save input is received. In this way, the undisplayed touch input content can be automatically stored, so that information omission is avoided, and subsequent users can conveniently view the content undisplayed in the touch display screen.

In other embodiments, the user may directly invoke the saved first input content or the saved second input content for viewing. Optionally, the types of the input contents that the user is allowed to view in the different modes may also be limited, for example, in the first mode, the user is only allowed to invoke the first input contents for viewing, and in the second mode, the user is only allowed to invoke the second input contents for viewing. Namely, the flow of this embodiment is: in the first mode, after receiving the first touch input, the first input is displayed in the touch display screen, if the second touch input is received, the second input content is not displayed, the second input content is automatically stored, and after subsequently switching to the second mode, the stored second input content can be checked. In the second mode, after receiving the second touch input, the second input is displayed in the touch display screen, if the first touch input is received, the first input content is not displayed, the first input content is automatically stored, and after subsequently switching to the first mode, the stored first input content can be checked.

In still other embodiments, the saving the first input content in response to the first save input to the first save control may include:

in response to a first save input to the first save control, saving the first input content to a blank first page of the first memory region.

The saving the second input content in response to the second save input to the second save control may include:

in response to a second save input to the second save control, saving the second input content to a blank second page of the second memory region.

In this embodiment, in order to facilitate the user's viewing and subsequent calling, the first input content and the second input content are respectively stored in different storage areas. Moreover, because the user usually writes one page before writing the next page in the writing panel or the touch display screen, the first input content can be saved in pages, that is, the first input content to be saved is saved into a new page every time the user receives the first saving input, and the second input content is also the same. In this case, the subsequent user can further conveniently view the input content and search the information.

In the case of paged saving based on the first input content and the second input content, in a further embodiment, the method may further include:

under the condition that the display device is in the first mode, responding to a first switching input of a first switching control, and displaying first target input content on the touch display screen, wherein the first target input content is first input content stored in a first page selected by the first switching input.

And under the condition that the display equipment is in the second mode, responding to a second switching input of a second switching control, and displaying second target input content on the touch display screen, wherein the second target input content is second input content stored in a second page selected by the second switching input.

In this embodiment, in the first mode, the user may call the stored first input content to display, and at this time, the user may perform switching input on the first switching control to view the content stored in each first page and select the first page that is desired to be displayed. Similarly, in the second mode, the user may invoke the stored second input content to display, and at this time, the user may check the content stored in each second page by performing switching input on the second switching control, and select the second page that is desired to be displayed. In this way, the user can conveniently find the content which the user wants to view, and the content stored in each page can be completely displayed on the touch display screen, so that the situation that the data size is too large and the content cannot be completely displayed is avoided, and the display of the history input content by touch display is facilitated.

Furthermore, in some embodiments, the input content allowed to be viewed in each mode may not be limited, that is, the first input content and the second input content may be viewed in each mode, and in this case, similarly to the above-described embodiments, only the mode in which the display device is located is not limited, and the first target input content can be displayed as long as the first switching input is received, and the second target input content can be displayed as long as the second switching input is received.

In still other embodiments of the present disclosure, the method may further comprise:

under the condition that the erasing function of the display device is not in a shielding state and the display device is in the first mode, in response to a first erasing input to the writing panel, an erasing area corresponding to the first erasing input is identified, and display content corresponding to the erasing area in the touch display screen is deleted.

The writing panels on both sides are written by a physical pen (e.g. chalk), so the first erasing input is a physical erasing input, for example, the first erasing input may be an erasing input of a physical eraser (i.e. an eraser with a fixed size), or may be an erasing input of an object with an area larger than a preset size, such as an erasing input of a human hand or a towel.

And under the condition that the erasing function of the display device is not in a shielding state and the display device is in the second mode, responding to a second erasing input to the touch display screen, and deleting display content corresponding to the second erasing input in the touch display screen.

Here, the second erasing input may be a dragging input to the erasing control, for example, an input of dragging the erasing key in a state where the erasing key is pressed for a long time. Or, the second erasing input may include a selection input and a deletion input for the target display area, that is, the target display area is selected, and then the content in the target display area is deleted by clicking a deletion control. The present disclosure does not limit the specific contents of the second erasure input.

In this embodiment, the display device may be provided with an erasing function, and the content displayed in the touch display screen can be erased when the erasing function is not shielded. In the first mode, because the content in the writing panel is displayed in the touch display screen, when the first erasing input to the writing panel is detected, an erasing function can be simulated to erase the content synchronously displayed in the writing panel and the touch display screen, so that the effect of correspondingly erasing the same displayed content in the touch display screen is realized while the chalk handwriting is actually erased. In the second mode, since the displayed content is the input content of the touch display screen, when a second erasing input to the touch display screen is received, the corresponding displayed content is deleted. Under the condition, the display process of the display device on the input content in the writing panel and the touch display screen is perfected, and when the user needs to modify or delete the input content, the input content can be erased through the erasing input.

In the case where a user is likely to touch the writing panel while the user is writing on the writing panel, for example, the user may press the left hand on the writing panel and write the right hand, and the left hand may be mistaken for an erasure input. Based on this, in other embodiments, in a case where the erasing function of the display device is not in the shielding state and the display device is in the first mode, before responding to the first erasing input to the writing panel, the method may further include:

under the condition that a third touch input to the writing panel is received, detecting the size of a touch screen area corresponding to the third touch input;

and under the condition that the size is matched with the preset eraser size, determining the third touch input as the first erasing input.

In this embodiment, after receiving a third touch input to the writing panel, first, a size of a touch screen area corresponding to the third touch input is detected, and by comparing the size with a preset eraser size, it can be determined whether the third touch input is currently caused to be an eraser, if not, the third touch input is considered not to be the first erase input, possibly to be a false input, and not to be responded, and if the third touch input is caused to be an eraser, the third touch input is considered to be the first erase input, and the third touch input is responded to the first erase input to be erased. By the method, the accuracy of information erasing in the first mode is improved, the display content in the touch display screen is synchronously erased only when the content in the writing panel is erased by using the eraser as far as possible, and the possibility of mistaken erasing is reduced.

In some scenarios, the user may simply place the eraser very close to the writing panel, for example, if the user lifts the eraser before the writing panel but does not determine what portion of the content to erase, then infrared light may be touched due to the proximity of the eraser to the writing panel, resulting in the detection of a first erase input, but the content on the writing panel is not actually erased, resulting in a false erase condition if the first erase input is responded to directly.

Based on this, in a further embodiment, after the determining that the third touch input is the first erase input, the method may further include:

and under the condition that the touch screen area corresponding to the first erasing input is not changed, not responding to the first erasing input.

Accordingly, the identifying an erased area corresponding to the first erasing input in response to the first erasing input to the writing panel may include:

under the condition that the touch screen area corresponding to the first erasing input changes, responding to the first erasing input to the writing panel, and identifying the erasing area corresponding to the first erasing input, wherein the erasing area is the touch screen area corresponding to the first erasing input.

In this embodiment, when the touch screen area corresponding to the first erasing input is not changed, the first erasing input indicates that the eraser is merely placed on the writing panel or very close to the writing panel, and is not moved. And when the touch screen area corresponding to the first erasing input is changed, the board eraser is indicated to move on the writing panel, and the board eraser moves on the writing panel, which generally indicates that the user is erasing with the board eraser, so that the content on the touch display screen can be erased in response to the first erasing input. The method can avoid the situation that the effective content on the touch display screen is deleted by mistake as far as possible, and improves the reliability and the accuracy during erasing.

In other embodiments of the present disclosure, the method may further include:

in response to a masking input to the erasure control, masking an erasure function of the display device;

under the condition that the erasing function is in a shielding state, under the first mode, under the condition that a second erasing input is received, keeping the content displayed in the touch display screen unchanged;

and under the condition that the erasing function is in a shielding state, not responding to a second erasing input to the touch display screen in the second mode.

In this embodiment, the erasing function of the display device may be masked, and after the erasing function is masked, in the second mode, the second erasing input of the user to the touch display screen may not be responded, that is, the user may only perform the touch input to the touch display screen, but may not perform the erasing. In the first mode, if the user erases the content in the writing panel by using the eraser, only the physical writing (such as chalk) on the writing panel is erased, but the same content is not erased synchronously in the touch display screen. Under the condition, the content different from the content written in the writing panel can be displayed in the touch display screen, so that the user can simultaneously check the previously written content and the subsequently written content through the writing panel and the touch display screen in the first mode, and the convenience of the user is improved.

To facilitate understanding of the contents of the above embodiments, the above embodiments are described below by way of example. Assuming that the first input content can be paged and saved to the first storage area, the display device is in the first mode, and the erasing function of the display device is in a shielding state. The working process of the display device is as follows:

step one, when the writing panel finishes the first edition writing, the touch display screen synchronously displays the first edition writing content. At this time, the user triggers the first saving control, and then the first version of the written content is saved in a first page of the first storage area.

And secondly, erasing the first edition writing on the writing panel through the board eraser, wherein the touch display screen does not synchronously erase the self-displayed content due to the shielded erasing function, so that the touch display screen keeps displaying the first edition writing content.

And step three, completing second edition writing on the writing panel, wherein the writing panel displays second edition writing content, and the touch display screen displays first edition writing content. So that the user can view both versions of the written content at the same time.

And step four, the user can trigger the first saving control to save the second version of the written content into the other first page of the first storage area.

And step five, because the touch screen is in the first mode at the moment, the touch screen can be switched through the first switching control, so that the touch screen can display the writing content of the first version and can also display the writing content of the second version.

And step six, the user can continuously erase the content of the writing panel and rewrite new content, and the written content can be continuously stored in a new page, so that the user can conveniently switch display on the touch display screen.

It should be noted that, after the erase function mask is applied, the touch display screen does not respond to the first erase input of the user on the writing panel, so that the touch display screen cannot synchronously display the first input content in the writing panel after the user erases the writing panel. In the first mode, after the erasing function is shielded, the touch display screen synchronously displays first input content before receiving a first erasing input; after receiving the first erasing input, the touch display screen does not synchronously display the input content newly written by the writing panel after erasing, in this case, the touch display screen can only display the content displayed before erasing, or after erasing, if the input content written by the writing panel is stored in a new first page, the touch display screen can display the content stored in the new first page by responding to the first switching input.

Based on the above method embodiments, the present disclosure also provides an information display apparatus 300, and referring to fig. 11, fig. 11 is a block diagram illustrating an information display apparatus 300 according to an exemplary embodiment.

In this embodiment, the user can perform touch input on the touch display screen, and can display the input of the touch input on the touch display screen when the display device is in the second mode. Under the condition, the user can adjust the source of the content displayed on the touch display screen only by adjusting the mode of the display device in the process of using the display device, so that the user can watch the content written on each part in the display device through the touch display screen, and the user can watch the display device conveniently. Moreover, the content displayed on the touch display screen is distinguished through the second mode and the first mode, the conflict between the content written on the touch display screen and the content written on the writing panel during display can be avoided, the touch display screen can be guaranteed to display the written content through the original size as far as possible, and the display effect is better.

After the target application software determines the position of the touch input based on the initial coordinates, the initial coordinates of the first touch input and the second touch input need to be converted from the first rectangular coordinate system to coordinates in the second rectangular coordinate system.
