Description

[0002] Currently, when doctors use interactive tablets to view X-rays, they need to place the X-rays on the interactive tablet's display screen and open the "light box" software of the interactive tablet. After the "light box" software is turned on, the display screen brightness will be automatically adjusted to the specified brightness value to provide a light box lighting effect for doctors to use when viewing X-rays.

[0003] However, when using the "light box" software to view X-rays, the user needs to operate the display screen to open the tool window, select the "light box" software to open, and then place the X-ray on the display screen of the interactive tablet. The entire operation process requires many steps, and the display control process is relatively cumbersome. In addition, since a part of the display screen is blocked by the X-ray film at this time, when using the writing or control function of the interactive tablet, if you want to set the display properties or operation properties, sometimes the setting interface is blocked by the X-ray film. At this time, you need to take the X-ray film away and put it back after the setting is completed, which is cumbersome. Summary of the invention

[0031] In order to make the purpose, technical scheme and advantages of the present application clearer, the specific embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. It is understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for the convenience of description, only the part related to the present application but not all the contents are shown in the accompanying drawings. Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flow charts. Although the flow chart describes each operation (or step) as a sequential process, many of the operations therein can be implemented in parallel, concurrently or simultaneously. In addition, the order of each operation can be rearranged. The process can be terminated when its operation is completed, but it can also have additional steps not included in the accompanying drawings. The process can correspond to a method, a function, a procedure, a subroutine, a subprogram, etc.

[0032] The display control method provided by the present application aims to achieve simple and efficient control operation of brightness by triggering the control process of brightness through elastic wave detection and matching, simplify the control process of brightness, and then optimize the user's operating experience when using the brightness of the interactive tablet to view X-rays. For traditional interactive tablets, when using brightness to view X-rays, it is necessary to perform cumbersome operations to open the "light box" software. The "light box" software controls the brightness to a brightness value suitable for viewing the X-ray, and then the X-ray is attached to the display screen for viewing. Obviously, the entire operation process requires more interactive steps. For large-size display screens, users need to walk to both sides of the display screen to click to open the toolbox window on the sidebar, open the "light box" software from it, and then walk back to the center of the display screen to use the software. The whole process has a poor operating experience. Based on this, a display control method of an embodiment of the present application is provided to solve the technical problem of the cumbersome existing display control process.

[0033] Embodiment 1:

[0034] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only the parts related to the present application, rather than all structures, are shown in the accompanying drawings.

[0035] It should be noted that, in the present application, relational terms such as first and second are only used to distinguish one entity or operation or object from another entity or operation or object, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations or objects. For example, the "first" and "second" of the first touch operation and the second touch operation are used to distinguish the interactive operations of touching the display screen cover at two different times. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances. In addition, in the description of the present application, unless otherwise specified, "multiple" means two or more. "And / or" describes the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0036] The display control method provided in the embodiments of the present application can be executed by a display control device, which can be implemented by software and / or hardware, and the display control device can be composed of two or more physical entities, or can be composed of one physical entity. For example, the display control device can be a computer with a touch function, a tablet or an interactive tablet or other smart device.

[0037] For ease of understanding, the interactive tablet is used as a display control device for exemplary description in the embodiment. Among them, the interactive tablet can be an integrated device that operates the content displayed on the display tablet and realizes human-computer interaction through touch technology, which integrates one or more functions such as a projector, an electronic whiteboard, a screen, an audio system, a television, and a video conferencing terminal. In actual applications, the hardware part of the interactive tablet is composed of parts such as a display screen and an intelligent processing system, which are combined together by an integral structural member, and are also supported by a dedicated software system, wherein the display screen has a touch function. In the embodiment, the display screen displays an electronic whiteboard, and the user can touch the display screen with a finger or a touch pen, and the intelligent processing system performs corresponding interactive operations according to the touch operation input by the user. Typically, the interactive tablet is installed with at least one type of operating system, wherein the operating system includes but is not limited to systems such as Android system, Linux system, Windows system, Huawei Hongmeng system or Mac operating system, and the touch operation received by the display screen is processed by the operating system to realize the corresponding human-computer interaction operation.

[0038] The interactive tablet is equipped with a display screen with a touch function, which can be an infrared display screen, a capacitive display screen, a resistive display screen, an electromagnetic display screen or a pressure-sensitive display screen. On the display screen with a touch function, the user can touch the display screen with a finger or a writing pen to achieve touch operation. Correspondingly, the interactive tablet detects the touch position and responds according to the touch position to achieve the touch function. When the touch sensing modules used on the display screen with a touch function are different, the original touch signals collected by the touch sensing modules are different, and the converted touch signals are not completely the same.

[0039] For an infrared display screen, the touch sensing module is an infrared touch frame, and the touch signal collected by it may include a signal indicating that the infrared rays are blocked, and the converted touch signal may include a position touch signal, and the position touch signal may include the X coordinate and Y coordinate of the touch position. For a capacitive display screen, the touch sensing module is a capacitive touch panel, and the touch signal collected by it may include the current flowing through each electrode of the touch screen, and the converted touch signal may include a position touch signal, and the position touch signal may include the X coordinate and Y coordinate of the touch position. For a resistive display screen, the touch sensing module is a resistive touch panel, and the touch signal collected by it may include the voltage of the touch position, and the converted touch signal may include a position touch signal, and the position touch signal may include the X coordinate and Y coordinate of the touch position. For an electromagnetic display screen, the touch sensing module is an electromagnetic panel, and the touch signal collected by it may include the change in magnetic flux and the frequency of the received electromagnetic signal, and the converted touch signal may include a position touch signal corresponding to the change in magnetic flux and a pressure signal corresponding to the frequency, and the position touch signal may include the X coordinate and Y coordinate of the touch position; the pressure signal may include a pressure value. For a pressure-sensitive display screen, the touch sensing module is a pressure sensor, and the touch signal collected by the touch sensing module may include a pressure signal. The converted touch signal may include a position touch signal, and the position touch signal may include an X coordinate and a Y coordinate of the touch position.

[0040] Figure 1 A flow chart of a display control method provided in the first embodiment of the present application is given, referring to Figure 1 , the display control method specifically includes:

[0041] S110, receiving a first touch operation on a display screen, and detecting a first elastic wave feature corresponding to the first touch operation.

[0042] Specifically, during the use of the interactive tablet for medical scenarios, the user realizes human-computer interaction by touching the display screen of the interactive tablet. The touch operation can be a touch operation of various objects touching the display screen. The interactive tablet is pre-installed with a display control program. When the user triggers the display control program through human-computer interaction, the interactive tablet will control the brightness to a specified brightness value, so that the brightness of the interactive tablet simulates the lighting effect provided by a traditional X-ray light box. The user can then view the X-ray film by placing it on the display screen of the interactive tablet using the brightness provided by the interactive tablet.

[0043] When placing the X-ray film on the display screen, a corresponding fixing device is required to adsorb the X-ray film on the display screen. Here, the fixing device is used to fix the medical film on the display screen, and the medical film includes an X-ray film or a CT film, etc. The fixing device may include a base with a suction cup on one side, and the fixing device is adsorbed on the display screen of the interactive flat panel by using the base. The fixing device also includes a clamping structure, a magnetic structure or an adhesive structure, so that after the fixing device is adsorbed on the display screen, the fixing device is used to fix the medical film on the display screen of the interactive flat panel in the form of clamping, pasting, adsorption, etc. The fixing device can also be a base with a magnetic structure on one side. At this time, the interactive flat panel uses its magnetic structure to adsorb the display screen corresponding to the interactive flat panel, and then the fixing device is adsorbed on the display screen of the interactive flat panel. When the fixing device is adsorbed on the display screen of the interactive flat panel, it contacts the display screen cover of the interactive flat panel to generate a touch operation, and this touch operation is defined as the first touch operation. The signal feature obtained by converting the elastic wave generated by the first touch operation is the first elastic wave feature. The elastic wave characteristics are detected by the piezoelectric elastic wave sensor of the interactive flat panel. The piezoelectric elastic wave sensor is arranged at the frame of the display screen or the inner side of the display screen cover. It can convert the elastic wave into a voltage signal, and transmit the voltage signal to an IC chip with a temperature compensation circuit through a flexible printed circuit board for amplification and processing, and then convert it into a digital touch signal, that is, the corresponding elastic wave characteristic, through an analog-to-digital conversion circuit.

[0044] Of course, depending on the different detection methods of the elastic wave sensor, the signal type converted from the elastic wave is different. For example, it can also be a change in magnetic flux, and then the corresponding digital information is generated according to the change in magnetic flux to realize the detection of the elastic wave.

[0045] It should be noted that when various objects touch the display screen cover of the interactive flat panel (including point touch and slide), elastic waves with corresponding object characteristics will be generated. The elastic wave starts from the contact point between the touch object and the display screen, and propagates along the display screen cover to the surroundings or to the inside of the cover. At this time, the piezoelectric elastic wave sensor located at the display screen frame or the inside of the display screen cover can convert the physical vibration signal of the elastic wave into a voltage signal, which is transmitted to the IC chip with a temperature compensation circuit through a flexible circuit board for amplification and processing, and converted into a digital touch signal through an analog-to-digital conversion circuit. It can be understood that different touch objects generate different elastic wave signals when touching the display screen cover, and the corresponding elastic wave characteristics (i.e., digital touch signals) are also different, so different touch objects can be distinguished by elastic wave characteristics. The elastic wave characteristics are used as input signals, and the identification of the touch object is output through the machine learning model, and the touch object corresponding to the elastic wave characteristics is determined by the identification of the touch object. After the interactive flat panel obtains the elastic wave characteristics of the touch object, the elastic wave characteristics are input into the pre-trained machine learning model, and the machine learning model outputs the identification of the touch object corresponding to the elastic wave characteristics. Correspondingly, the elastic wave characteristics of the fixture are used as the model input signal, and the identification of the fixture is output through the machine learning model, so that the interactive tablet can detect the fixture.

[0046] More specifically, a detection scheme for touch operation of the embodiment of the present application is provided. The optical touch sensor is used to detect the touch characteristics (such as touch position, click, slide, etc.) of the touch operation, and the piezoelectric elastic wave sensor is used to detect the elastic wave characteristics of the touch operation.

[0047] In the embodiment of the present application, the display screen cover is a cover glass set on the surface of the interactive flat panel display screen to protect the display screen from being scratched by the touch object. In order to realize the touch function of the display screen, optical touch sensors are set on both sides of the display screen surface. When the touch object touches the display screen cover, the optical touch sensor scans the touch object through the light signal to sense the operation performed by the touch object on the display screen cover. Specifically, the optical touch sensor includes an infrared transmitter and an infrared receiver. The infrared transmitter is used to emit infrared light, and the infrared receiver is used to receive infrared light. The infrared light densely distributed in different directions is used to form a beam grid to locate the touch point. Exemplarily, M infrared transmitters are set on one side of the horizontal direction of the display screen, and N infrared transmitters are set on one side of the vertical direction. Correspondingly, M infrared receivers are set on the other side of the horizontal direction, and N infrared receivers are set on the other side of the vertical direction. The infrared transmitter emits infrared light at a certain frequency, and the corresponding infrared receiver receives infrared light at a certain frequency. When the touch object touches the display screen cover, the touch object will completely or partially block one or more vertical and horizontal infrared lights, and then obtain an M*N infrared light intensity pixel map. First, find a position greater than the first light intensity threshold on the infrared light intensity pixel map. The first light intensity threshold represents a real and effective touch, rather than noise or the light intensity measured when the infrared light is half-blocked when an object is close but not completely touched. The real touch position is the touch position when the touch object contacts the display cover. Further, find a position greater than the second light intensity threshold in the vicinity of the real touch position. The second light intensity threshold is greater than the noise value, which can represent the extension of the real touch area. Mark the position greater than the second light intensity threshold in the vicinity of the real touch position as a valid touch area. The area of ​​the touch area is the contact area between the touch object and the display cover. When the touch object moves on the display cover, the infrared light intensity pixel map with multiple frames of time continuous records the touch position and contact area of ​​the touch object on the display cover. The moving speed of the touch object on the display cover can be obtained through the touch position and contact area recorded in the continuous frames. When the touch object leaves the display cover, the infrared light is less blocked by the touch object. If the touch position in the previous frame of the infrared light intensity pixel map, the relative position in the current infrared light intensity pixel map, and the pixels in the adjacent area do not exceed the third light intensity threshold, then it is determined that the relationship between the touch object and the display cover is out of touch, and the third light intensity threshold represents the maximum light intensity when out of touch. It is understandable that when the user touches the display cover of the display screen with a touch object, the optical touch sensor installed on the display screen will measure the contact area between the touch object and the display cover, the moving speed of the touch object on the display cover, and the touch position when the touch object contacts the display cover. That is, touch features such as contact area, moving speed, and touch position are all measured by the optical touch sensor.

[0048] On the other hand, when the piezoelectric elastic wave sensor detects the elastic wave characteristics, it first converts the physical vibration signal of the elastic wave into a voltage signal. The continuous voltage signal will be scanned at a certain frequency f. When its voltage value is greater than the set first voltage threshold V1, the voltage value will be recorded as an effective piezoelectric value higher than the noise, otherwise it will be recorded as zero voltage. It should be noted that since the circuit noise will change with the change of temperature, and the coupling coefficient of the piezoelectric material will also change accordingly with the temperature, the voltage threshold can change accordingly with the change of temperature. Furthermore, the continuous recording of K voltage signals is an elastic wave signal segment, and the duration of the elastic wave signal segment is T. 0 (T 0 =K / f). In the elastic wave signal segment, if none of the K signals is greater than the first voltage threshold V1, the strength of the elastic wave signal segment does not reach the effective touch strength and is discarded; otherwise, it is recorded as a valid digital touch signal (i.e., elastic wave feature).

[0049] Furthermore, according to the different characteristic quantities such as the generation time and frequency of the elastic wave characteristic signal, some noise signals can be removed, such as external vibration, internal speaker or frame vibration, and other vibration signals that are not from touch operations. In addition, combined with the detection information of the optical touch sensor, the time period when the valid signal appears can be determined, and the elastic wave signals in other time periods are all signals caused by non-touch. Removing non-valid touch signals in different time periods is conducive to the identification and judgment of touch objects in subsequent steps.

[0050] S120. Compare the first elastic wave feature with a pre-stored standard elastic wave feature, wherein the standard elastic wave feature is an elastic wave feature generated when a fixed device touches the display screen, and the standard elastic wave feature is pre-bound and stored with corresponding display control information, and the display control information is used to control the brightness of a specified area of ​​the display screen to a set value.

[0051] The interactive tablet can query the pre-stored mapping relationship based on the detected first elastic wave feature, and compare and match the first elastic wave feature. Prior to this, the interactive tablet pre-collects the elastic wave feature of the fixed device and defines this elastic wave feature as the standard elastic wave feature. When the first elastic wave feature matches the standard elastic wave feature, it can be determined that the touch object of the current display screen is a fixed device. By binding the standard elastic wave feature to the display control information, the display control information is used to trigger the display control program to control the brightness of the specified area of ​​the display screen to a set value. It can be understood that if it is determined through a mapping relationship query that the first elastic wave feature matches the standard elastic wave feature, the display control information can be used to trigger the display control program to control the brightness.

[0052] Specifically, when constructing the mapping relationship, the interactive flat panel pops up a binding interface between the standard elastic wave features and the display control information based on the relevant interaction operations of the user. At this time, by adsorbing the fixing device on the display screen of the interactive flat panel to generate corresponding touch operations, the interactive flat panel detects the corresponding elastic wave features based on the touch operations, and stores the elastic wave features as the standard elastic wave features corresponding to the display control information, thereby completing the construction of the mapping relationship. Moreover, according to actual needs, the display control information can be modified through this binding interface, such as operations like increasing the brightness value.

[0053] Based on the pre-construction and storage of the above mapping relationship, subsequent query through the mapping relationship can determine whether the currently detected first elastic wave feature matches the standard elastic wave feature.

[0054] S130. Determine that the first elastic wave feature matches the standard elastic wave feature, and in response to the first touch operation, control the brightness of the specified area of the display screen to a set value based on the display control information; determine that the first elastic wave feature does not match the standard elastic wave feature, and obtain the display attribute or operation attribute corresponding to the first touch operation according to the first elastic wave feature; generate a writing trajectory corresponding to the first touch operation according to the display attribute, or perform an operation response to the first touch operation according to the operation attribute. The display attribute is used to indicate the display manner of the writing stroke on the interface of the whiteboard application. The difference in the display attribute can be the difference in color, thickness, or line type (such as solid and dashed lines), etc., or it can be a combination of multiple display attributes, such as including both color and line type at the same time. The operation attribute includes writing operation, moving operation, erasing operation, selecting operation, and / or mouse operation.

[0055] Finally, based on the query results of the above mapping relationship, it is determined whether the detected first elastic wave matches the standard elastic wave feature. It is understandable that the first elastic wave feature is input into a pre-trained machine learning model. If it is detected that the identifier of the touch object corresponding to the standard elastic wave feature matches the identifier of the touch object corresponding to the standard elastic wave feature, then the first elastic wave feature matches the standard elastic wave feature. At this time, the display control information bound to the standard elastic wave feature is extracted according to the mapping relationship, and the display control program is triggered by the display control information, and then the brightness of the specified area is controlled to the set value, thereby completing the display control process based on elastic wave feature detection and matching in the embodiment of the present application. It is understandable that during the entire process, the user only needs to adsorb the fixing device on the display screen of the interactive flat panel to realize display control and use brightness to view medical films such as X-rays. On the other hand, if no standard elastic wave feature matching the first elastic wave feature is detected through the mapping relationship query, the display attribute or operation attribute corresponding to the first touch operation is obtained according to the first elastic wave feature, so as to generate corresponding writing handwriting according to the display attribute or perform corresponding operation response according to the operation attribute, and directly perform display or operation response through the display attribute or operation attribute associated with the elastic wave feature, without going through a complicated operation process, and there is no problem of medical film affecting the operation area. Therefore, the embodiment of the present application can conveniently and quickly realize the brightness adjustment of the display screen and the touch operation response.

[0056] Exemplarily, when a user uses an interactive tablet to view an X-ray film, refer to Figure 2 First, the fixing device 11 is adsorbed on the display screen 12 of the interactive tablet. At this time, the interactive tablet performs elastic wave detection and matching on the fixing device 11 based on the above steps S110~S130, and then responds to the touch operation generated by the current fixing device 11 touching the display screen 12, controls the brightness of the display screen based on the display control information, and simulates the X-ray light box to provide corresponding brightness light. At this time, the user uses the fixing device to stick the X-ray film on the display screen, and can check the X-ray film with the help of the light provided by the display screen. When the user touches the display screen with a finger or a pen, the interactive tablet performs elastic wave detection and comparison based on the above steps S110~S130, and after determining that its elastic wave characteristics do not match the standard elastic wave characteristics, it detects the touch characteristics of the current touch operation, and then displays the corresponding touch handwriting on the display screen according to the touch trajectory of the touch characteristics, thereby completing the response to the touch operation.

[0057] As described above, when the touch object performs the first touch operation on the display screen, the corresponding operation is performed by detecting the first elastic wave feature corresponding to the first touch operation. If the first elastic wave feature matches the elastic wave feature generated by the fixed device touching the display screen, the brightness of the specified area of ​​the display screen is controlled to be the set value, so that when the fixed device is detected to touch the display screen, the brightness of the specified area of ​​the display screen can be controlled for the user to view the medical film, which simplifies the control process of the brightness of the specified area of ​​the display screen. If the first elastic wave feature does not match the elastic wave feature generated by the fixed device touching the display screen, the display attribute or operation attribute corresponding to the first touch operation is obtained according to the first elastic wave feature, so as to generate the corresponding writing handwriting according to the display attribute or perform the corresponding operation response according to the operation attribute, and directly perform the display or operation response through the display attribute or operation attribute associated with the elastic wave feature, without going through a complicated operation process. Therefore, the embodiment of the present application can conveniently and quickly realize the brightness adjustment of the display screen and the touch operation response.

[0058] Based on the above embodiments, a more specific implementation of the display control of the embodiment of the present application is provided. Among them, the embodiment of the present application performs the corresponding brightness split screen display operation according to the position where the fixed device touches the interactive flat panel. Figure 3 , a brightness split-screen control flow chart of an embodiment of the present application is provided, wherein the interactive flat panel of the embodiment of the present application responds to the first touch operation, and controls the brightness of the specified area of ​​the display screen to a set value based on the display control information, including:

[0059] S1301, in response to the first touch operation, determining a first touch position of the first touch operation;

[0060] S1302. Determine the split-screen area where the first touch position falls, and control the display screen brightness of the corresponding split-screen area to a set value based on the display control information. The split-screen area is determined by dividing the area according to the display area of ​​the display screen.

[0061] For example, refer to Figure 4When the user adsorbs the fixing device 11 on the display screen 12 of the interactive tablet, the interactive tablet, on the one hand, performs elastic wave detection and matching on the touch operation of the fixing device 11 based on the above steps S110 to S130, and on the other hand, detects the touch position of the touch operation of the fixing device 11 based on the optical touch sensor. Define this touch position as the first touch position, and determine the split-screen area where the first touch position falls. Prior to this, the interactive tablet pre-sets the split-screen area corresponding to the display area of ​​the display screen. Among them, the display area of ​​the display screen can be divided into two split-screen areas in half on the left and right, or a number of split-screen areas can be set according to the size of the X-ray film. Furthermore, when the interactive tablet responds to the touch operation generated by the current fixing device 11 touching the display screen 12, it first determines the split-screen area where the first touch position falls, and then controls the display screen brightness of the split-screen area based on the display control information. Figure 4 As shown, the split screen area where the first processing position corresponding to the fixing device 11 falls simulates an X-ray film light box to provide corresponding brightness illumination, and the user can cover the X-ray film on the split screen area and use the brightness provided by the split screen area to view the X-ray film. For the remaining display screen areas, related human-computer interaction operations can still be performed.

[0062] As described above, by realizing the brightness split-screen display through the split-screen area, adaptive control of the brightness display area can be realized. It is understandable that part of the display screen outside the brightness display area can be used to perform other human-computer interaction operations. By using the remaining display screen display area to perform related operations of X-ray film viewing while viewing the X-ray film, the user's operating experience can be further improved and the user's related work needs when viewing the X-ray film can be met.

[0063] On the basis of the above embodiment, the embodiment of the present application further performs selection control of the brightness display area. After responding to the first touch operation and controlling the brightness of the designated area of ​​the display screen to a set value based on the display control information, the embodiment of the present application further includes:

[0064] A selection bar for the brightness display area is displayed at a designated position on the display screen, wherein the selection bar includes a plurality of control options for the brightness display area.

[0065] For example, Figure 4As shown, a selection bar is displayed below the interactive flat panel display screen, and the selection bar includes control options such as "split screen", "full screen", "horizontal screen" and "exit". Correspondingly, the user can make the interactive flat panel adaptively switch different styles of the brightness display area by touching and selecting the corresponding control option. For example, when the user touches and selects the "full screen" control option, the interactive flat panel will switch the brightness of the current split screen display to full screen display; when the user touches and selects the "horizontal screen" control option, the brightness of the current split screen display will be switched to horizontal screen display; when the user touches and selects the "exit" control option, the current brightness split screen display mode will be exited and the display will be restored to the initial display state.

[0066] As described above, by providing different control options for the brightness display area, the display area of ​​the display screen can meet the user's different display mode requirements for the brightness display area when viewing X-rays, further improving the user's interactive operation experience.

[0067] Specifically, the interactive tablet calls the recovery control corresponding to the fourth touch operation in response to the received fourth touch operation, and controls the brightness of the specified area of ​​the display screen to be restored to the initial state value based on the recovery control. For example, the user clicks the "Exit" option in the selection bar, and the interactive tablet detects the corresponding touch operation and defines the touch operation as the fourth touch operation. In response to the fourth touch operation, according to the "Exit" option selected by the touch operation, the corresponding recovery control is called, and the brightness of the specified area of ​​the display screen is controlled to be restored to the initial state value using the recovery control. That is, the corresponding display mode of the current brightness is exited through the fourth touch operation, and the display screen is restored to the initial display state.

[0068] In addition, based on the above-mentioned embodiment, the interactive tablet of the embodiment of the present application controls the brightness of the designated area of ​​the display screen to be the set value based on the display control information in response to the first touch operation, and then controls the brightness of the designated area of ​​the display screen to be restored to the initial state value based on the elastic wave feature detection to determine that the fixing device is detached from the display screen. Specifically, it is different from the above-mentioned touch operation to trigger the recovery control, and then exit the brightness display mode of the designated area of ​​the current display screen. Here, the elastic wave feature of the fixing device is detected by a piezoelectric elastic wave sensor. When it is detected that the elastic wave feature of the fixing device disappears, it triggers the exit of the brightness display mode of the designated area of ​​the current display screen, and restores the initial display state of the designated area of ​​the display screen. It can be understood that when the fixing device is adsorbed on the display screen, the piezoelectric elastic wave sensor can detect the corresponding elastic wave feature. Similarly, when the fixing device is detached from the display screen, the piezoelectric elastic wave sensor detects that its elastic wave feature disappears. Based on this detection result, the brightness recovery of the designated area of ​​the display screen can be triggered.

[0069] Based on the above embodiments, the embodiment of the present application performs focus display control corresponding to brightness, referring to Figure 5 , providing a flow chart of brightness focus display control. Among them, after the interactive tablet of the embodiment of the present application controls the brightness of the specified area of ​​the display screen to a set value based on the display control information in response to the first touch operation, it also includes:

[0070] S140, receiving a second touch operation on the split-screen area, and detecting a second elastic wave feature corresponding to the second touch operation;

[0071] S150: Determine that the second elastic wave feature matches a predefined elastic wave feature, determine a second touch position of the second touch operation in response to the second touch operation, and focus and display the second touch position.

[0072] Specifically, in order to simplify the operation process of brightness focus display, the embodiment of the present application collects the elastic wave characteristics of the corresponding touch tool in advance and uses this elastic wave characteristic as a predefined elastic wave characteristic. Further, referring to the construction method of the above mapping relationship, this predefined elastic wave characteristic is pre-bound to the brightness focus display information, and the brightness focus display information is used to control the brightness for focusing display of the corresponding touch position.

[0073] Afterwards, when the user uses a touch tool to click on the split-screen area, the touch operation received by the interactive tablet is defined as the second touch operation. The elastic wave feature of the second touch operation is detected by the piezoelectric elastic wave sensor of the interactive tablet, and the elastic wave feature is defined as the second elastic wave feature. This second elastic wave feature is further compared with the predefined elastic wave feature. If the two match, the second touch operation is responded to and the brightness focus display operation is performed. Otherwise, the touch operation is ignored. Wherein, when responding to the second touch operation, based on the binding relationship between the predefined elastic wave feature and the brightness focus display information, the brightness focus display information is used to control the current brightness for focus display. In addition, the touch position of the second touch operation is detected by the optical touch sensor, and this touch position is defined as the second touch position. The brightness of the set range is further displayed with the second touch position as the center, and the brightness of the remaining positions is not displayed or a mask display effect is provided to reflect the focus display effect of the second touch position.

[0074] For example, refer to Figure 6 , using the touch pen 13 as a touch tool, the elastic wave characteristics of the touch pen 13 are set to predefined elastic wave characteristics and bound to the brightness focus display information. Figure 6 As shown, when the touch pen 13 is used to touch the split screen area of ​​the display screen 12, the focus display effect within the range corresponding to the touch position is displayed according to the touch position of the touch pen 13.

[0075] It should be noted that, since the X-ray film is attached to the display screen of the interactive tablet when viewing it, the touch tool needs to touch the split screen area across the X-ray film. In order to ensure the accuracy of the comparison of the elastic wave features, when collecting the predefined elastic wave features, it is necessary to use the touch tool to touch the display screen of the interactive tablet across the X-ray film, and then set the corresponding elastic wave features generated by the touch operation as the predefined elastic wave features, so as to facilitate the subsequent accurate comparison and matching according to the elastic wave features of the second touch operation of the touch tool.

[0076] As described above, by focusing the brightness display area, it is convenient for users to view the details of the X-ray film, thereby improving the efficiency and user experience of viewing the X-ray film.

[0077] Further, based on the above embodiment, the embodiment of the present application corresponds to a zoom operation of the focused display area. Wherein, after determining the second touch position of the second touch operation and focusing on the second touch position, the interactive tablet further includes:

[0078] In response to the received third touch operation, a zoom operation corresponding to the focused display area is performed.

[0079] Exemplarily, based on the focused display area provided by the brightness focus display, the embodiment of the present application performs a zoom operation on the focused display area by responding to a touch operation (ie, a third touch operation) predefined by the user. Figure 7 As shown, the user touches the display screen with a touch pen and slides upwards. At this time, the interactive tablet detects the touch operation and determines that the touch operation is a predefined touch operation for controlling the zooming of the focused display area. At this time, in response to the third touch operation, the focused display area is zoomed in. Similarly, the user touches the display screen with a touch pen and slides downwards. At this time, the interactive tablet detects the touch operation and determines that the touch operation is a predefined touch operation for controlling the zooming of the focused display area. At this time, in response to the third touch operation, the focused display area is zoomed out.

[0080] In addition, in some embodiments, the focus display area can also be controlled to be zoomed and displayed through corresponding interactive operations. For example, the pressure value of the touch pen touching the focus display area is detected by a pressure-sensitive pressure sensor, and the size of the focus display area is adjusted according to the change in pressure. Specifically, the essence of the pressure-sensitive pressure sensor is a piezoresistor, which can cause a change in resistance according to the change in pressure. By applying a constant voltage to the pressure-sensitive sensor, the output current value can be detected, and then the change in the piezoresistor can be obtained, thereby inferring the change in sensor pressure. The piezoresistor is set under the display cover or at the frame. Due to the superposition of force, multiple pressure sensors can sense pressure information at different positions. Combined with the optical touch sensor, the pressure of each touch point can be inferred. Based on the above-mentioned pressure-sensitive sensor, the pressure value of the second touch operation can be detected, and then the size of the focus display area is adjusted according to the pressure value and the pre-set zoom size, so as to achieve adaptive adjustment of the focus display area.

[0081] As described above, through the adaptive adjustment of the focused display area, the focused display area can meet the real-time viewing needs of the user, further improving the user's operating experience.

[0082] On the basis of the above embodiment, the embodiment of the present application further provides an associated toolbar, wherein after the interactive tablet controls the brightness of the specified area of ​​the display screen to a set value based on the display control information in response to the first touch operation, it also includes:

[0083] A context toolbar is displayed on one side of the split screen area, wherein the context toolbar includes a plurality of predefined application options.

[0084] It is understandable that when the user is viewing the X-ray film, by displaying the associated toolbar, the user can use the corresponding application options to assist in viewing the X-ray film, so as to improve the viewing efficiency and interactive operation experience of the X-ray film. Among them, the application options may include display brightness adjustment, medical record viewing and X-ray film file creation. Figure 8 As shown, the context toolbar is displayed on one side of the split screen area. The management toolbar contains

[0085] Options such as "Display screen brightness adjustment", "Medical record review" and "X-ray file creation". When the user is viewing the X-ray film using the brightness provided by the split-screen area, if the brightness of the split-screen area needs to be adjusted, the user can click the "Display screen brightness adjustment" application option. At this time, the interactive tablet will pop up the display screen brightness adjustment interface on one side of the split-screen area for the user to choose to adjust the brightness of the current split-screen area. When the user needs to view the medical record corresponding to the current X-ray film, click the "Medical record review" application option. At this time, the interactive tablet will display the medical record list interface on one side of the split-screen area for the user to select the corresponding medical record for review. When the user needs to create an X-ray file based on the X-ray review results, click the "X-ray file creation" application option. At this time, the interactive tablet will display the X-ray file operation interface on one side of the split-screen area for the user to create the X-ray file.

[0086] As described above, by displaying the associated toolbar on one side of the split-screen area, the different associated needs of users when viewing X-rays can be adaptively met, the user's work efficiency can be improved, and more convenience can be provided for the user to view X-rays, further improving the user's operating experience.

[0089] The detection module 21 is used to receive a first touch operation on the display screen and detect a first elastic wave feature corresponding to the first touch operation;

[0107] As described above, when the touch object performs the first touch operation on the display screen, the corresponding operation is performed by detecting the first elastic wave feature corresponding to the first touch operation. If the first elastic wave feature matches the elastic wave feature generated by the fixed device touching the display screen, the brightness of the specified area of ​​the display screen is controlled to be the set value, so that when the fixed device is detected to touch the display screen, the brightness of the specified area of ​​the display screen can be controlled for the user to view the medical film, which simplifies the control process of the brightness of the specified area of ​​the display screen. If the first elastic wave feature does not match the elastic wave feature generated by the fixed device touching the display screen, the display attribute or operation attribute corresponding to the first touch operation is obtained according to the first elastic wave feature, so as to generate the corresponding writing handwriting according to the display attribute or perform the corresponding operation response according to the operation attribute, and directly perform the display or operation response through the display attribute or operation attribute associated with the elastic wave feature, without going through a complicated operation process.
