[0220] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the present disclosure will be described in further detail below in combination with the drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present disclosure.

[0221] The application scenarios described in the embodiments of the present disclosure are to more clearly illustrate the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Those of ordinary skill in the art can know that with the emergence of new application scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems. In the description of the present disclosure, unless otherwise specified, the meaning of "multiple" is two or more.

[0222] At present, LED display products suitable for indoor use have begun to appear in 135-inch to 165-inch splicing products, and with the progress of technology, they begin to be equipped with infrared touch frames to realize touch, video conferencing and other functions. However, in the process of use, especially in close-range operation or writing, the high brightness is very easy to cause visual fatigue and is very dazzling. LED display has very high brightness and can be spliced arbitrarily, and is very suitable for large venues, large conference rooms, and is very clear and bright for long-distance viewing. More and more LED splicing products have begun to be equipped with infrared touch frames to realize writing and touch functions, and are integrated with cameras, microphones, screen transmitters and other accessories, and are applied to conference scenarios. And on a very large size, it makes up for the seam problem of liquid crystal products.

[0223] After the LED splicing system is installed, there are two ways to adjust the brightness of the LED display. One is manual setting, which involves adjusting the display brightness through the system software. The other is to use the ambient light sensor installed in the system to adjust the LED display brightness based on the ambient light. Both of these methods are conventional brightness adjustment methods. The adjusted brightness is set to L0, which is the brightness value suitable for the current usage environment and for viewing from a distance. Based on current industry products, L0 may be around 500-600 nits. Because LED displays are bright, touch and writing operations require the user to be close to the screen, which can be very harmful to the human eye.

[0224] To solve the above technical problems, this embodiment proposes a more intelligent brightness adjustment method. When people operate at close range, the brightness of the user operation area can be lower than the brightness of other areas, thereby intelligently reducing the display brightness of the LED screen used by users operating at close range and improving the user experience.

[0225] In some examples, this embodiment provides a smart interactive flat panel, which includes but is not limited to LED splicing products and LCD products, and has the characteristics of large size and high brightness. Figure 1 As shown, it includes a display screen 100, a touch component 101, and a driving circuit 102, wherein:

[0226] The display screen 100 is used to display content;

[0227] The touch component 101 is used to receive touch operation instructions;

[0228] The driving circuit 102 includes a processor 103 and a memory 104. The memory 104 is used to store a program executable by the processor 103. The processor 103 is used to read the program in the memory 104 and perform the following steps:

[0229] Step 1) determining a first area and a second area of ​​a display area of ​​the display screen, wherein the first area and the second area do not overlap, wherein the first area includes at least part of the content of the display area, and the first area is configured to receive a user's touch operation instruction;

[0230] Step 2) Controlling the display brightness of the first area to be lower than the display brightness of the second area.

[0231] This embodiment divides the display area of ​​the display screen into two areas, namely the first area and the second area, wherein the first area is set to receive the user's touch operation instructions, that is, the first area is the area where the user performs close-range operations, and the second area can be configured as an area for display to facilitate users to watch from a distance. In some examples, the second area can also be configured as an area for receiving touch operation instructions, or the second area can be configured as an area for display and an area for receiving touch operations. This embodiment does not impose too many restrictions on this. This embodiment controls the display brightness of the first area to be lower than the display brightness of the second area, so that the display brightness of the first area operated by the user who operates the smart interactive tablet at close range is reduced to be lower than the display brightness of the second area. Since the first area is the area where the user operates and the second area is the area where users watch from a distance, the brightness of the first area is lower than the brightness of the second area. This can ensure that it does not affect users watching from a distance while improving the user experience of users using the smart interactive tablet at close range, and will not cause visual fatigue due to the high brightness of the smart interactive tablet, thereby improving the user experience.

[0232] It should be noted that the first area and the second area divided in this embodiment are only an example of area division based on software or an example of area division based on algorithm, that is, the processor of the smart interactive tablet is used to divide the display screen into areas algorithmically or by software, and the presentation method is to distinguish the first area and the second area in the area displayed on the full-screen display screen through various forms such as area frames, area blocks, and dividing lines, but the above-mentioned area division does not exist in the hardware of the display screen.

[0233] In some examples, the content displayed in the first area includes at least a portion of the content in the display area.

[0234] In some examples, such as Figure 2 As shown, the second area 202 in this embodiment is the remaining area in the display area 200 except the first area 201; or Figure 3 As shown, the second area 302 in this embodiment is a portion of the remaining area in the display area 300 except the first area 301, wherein the second area does not overlap with the first area. In some examples, the shapes of the first area and the second area in this embodiment can be the same or different, and the shapes of the first area and the second area in this embodiment are not excessively limited. In some examples, the display area can be divided into a preset number of equal areas, for example, the display area can be divided into four equal parts, such as Figure 4AAs shown, there are four areas, 400a, 401a, 402a, and 403a, wherein the first area is located in one of the four areas, and the second area is located in any one of the other three areas except the first area. In some examples, the display area can also be divided into field-shaped areas, such as Figure 4B As shown, there are four regions, 400b, 401b, 402b, and 403b, wherein the first region is located in one of the four regions, and the second region is located in any one of the other three regions except the first region. The positional relationship between the first and second regions in this embodiment includes, but is not limited to, diagonally opposite, adjacent, and axially symmetrical, and this embodiment does not impose any additional restrictions on this.

[0235] In some examples, the content displayed in the first area in this embodiment includes the content of the second area, that is, the content of the first area in this embodiment includes the content of the second area. Optionally, the content displayed in the first area includes a thumbnail of the second area, or the content displayed in the first area includes the background of the second area, or the content displayed in the first area includes the core content of the second area, such as certain key icons, texts, images and other content; or the content displayed in the first area includes part or all of the content of the second area after removing the background. In implementation, the content of the second area that needs to be displayed in the first area is determined specifically according to user needs, and the content of the second area is copied to the first area for display. Since the first area is configured as the user's operation area, the content in the second area can be displayed in the first area, which is convenient for users to operate in the operation area (first area) when using a large screen, thereby improving the user experience. Among them, the content of the second area can be copied and displayed in the first area by zooming or panning, for example, the icon in the second area is zoomed and copied and displayed in the first area, or the content of the second area without the background is zoomed and copied and displayed in the first area, or all the content in the second area is zoomed and copied and displayed in the first area. The display method of the second area in the first area provided in this embodiment is only an example, and the display method determined based on the core idea of ​​the present disclosure belongs to the protection scope of the present disclosure.

[0236] In this embodiment, the partial content of the display area includes, but is not limited to, the background of the display area, icons in the display area, documents in the display area, pictures in the display area, and other content. The partial content of the display area also includes partial or all content in the second area, and partial or all content in areas other than the first and second areas.

[0237] In some examples, if the first area includes icons of the second area, this embodiment can receive touch operation instructions of the icons of the first area, and convert the touch operation instructions of the icons of the first area into touch operation instructions for controlling the icons of the second area. Optionally, a first icon is displayed in the second area; a second icon associated with the first icon is displayed in the first area; a first touch operation instruction of the first area for the second icon is received; and the first touch operation instruction of the first area for the second icon is converted into a second touch operation instruction for the first icon of the second area to control the second area. In implementation, when the first area includes the content of the second area, for example, icons of the second area are displayed in the first area, the user can operate the icons of the second area displayed in the first area. Since the screen size of the current display screen is large, it is inconvenient for the user to perform touch interaction. Through the method provided by this embodiment, certain key content in the larger screen can be displayed in the first area (an area that is convenient for the user to perform touch operations), so that the user can operate the key content displayed in the full screen in the first area at a close distance, effectively improving the user's operating experience on the large screen.

[0238] In some examples, the first touch operation instruction and the second touch operation instruction are used to distinguish between a touch operation on the second icon in the first area and a touch operation on the first icon in the second area. Essentially, the first touch operation instruction and the second touch operation instruction both conform to the definition of touch operation instructions in this embodiment. Optionally, the first touch operation instruction for the second icon includes, but is not limited to, a click icon operation instruction, an open icon operation instruction, a start icon operation instruction, and a delete icon operation instruction. The second touch operation instruction includes, but is not limited to, a click icon operation instruction, an open icon operation instruction, a start icon operation instruction, and a delete icon operation instruction. It should be noted that the first touch operation instruction and the second touch operation instruction correspond to each other. In implementation, the user only needs to perform the first touch operation instruction on the second icon in the first area. Accordingly, the processor of the smart interactive tablet in this embodiment will convert the first touch operation instruction into the second touch operation instruction for the first icon. Therefore, the first touch operation instruction for the second icon in this embodiment is equivalent to the second touch operation instruction for the first icon. For example, if a click operation is performed on the second icon in the first area, the click operation is correspondingly converted into a click operation on the first icon in the second area.

[0239] In some examples, the first icon displayed in the second area and the second icon associated with the first icon displayed in the first area may have the same or different shapes; the names of the two icons may be the same or different; the first icon and the second icon in this embodiment may be exactly the same or different; the position of the second icon in the first area may be the same as or different from the position of the first icon in the second area. In this embodiment, the first icon and the second icon are associated with each other, and this embodiment does not impose too many restrictions on the shape, name, color, position, etc. of the first icon and the second icon that are associated with each other. Figures 5A-5D As shown, this embodiment shows multiple ways of displaying a second icon associated with a first icon in a first area. Figure 5A It shows that only some of the icons in the second area are displayed in the first area, and the names corresponding to the icons are not displayed. Figure 5B It shows that all icons in the second area are placed in the first area, wherein the shape of each icon is changed; Figure 5B It shows that all icons in the second area are displayed in the corresponding positions of the first area, where icon 1 corresponds to the photo album, icon 2 corresponds to music, icon 3 corresponds to the calendar, icon 4 corresponds to settings, icon 5 corresponds to the application store, icon 6 corresponds to security maintenance, icon 7 corresponds to writing tools, and icon 8 corresponds to weather. Figure 5C It shows that all icons in the second area are scaled and then displayed in the first area, without displaying the icon names and the background of the second area; Figure 5D It should be noted that the way of displaying the icons in the second area in the first area in this embodiment is only an example, and the way of displaying icons determined based on the same inventive concept all fall within the scope of protection of this disclosure.

[0240] In some examples, after determining the first and second areas of the display area of ​​the display screen, this embodiment is further used to copy at least part of the content of the first area to the second area for display. Optionally, a writing instruction in the first area is received, and writing handwriting is generated in the first area according to the writing instruction; the writing handwriting generated in the first area is copied to the second area for display. After generating the writing handwriting in the first area, this embodiment copies the writing handwriting to the second area and retains the content that has been written. During implementation, when the user performs a writing operation in the first area, the writing-related content can be displayed in the second area, so that users watching from a distance can see the writing-related content of the writing user in real time, thereby improving the interactive experience.

[0241] In some examples, after copying at least part of the content of the first area to the second area for display, this embodiment may further remove the copied content of the first area's handwriting from the second area after determining that the writing instruction in the first area has ended. In some examples, the end of the writing instruction is determined by any one or more of the following methods: determining that writing is complete, determining to wait a preset time after writing is complete, determining to close or delete the first area, or determining to receive a user-triggered end instruction. This embodiment does not impose any additional limitations on how to determine the end of the writing instruction.

[0242] In some examples, this embodiment determines the first area by any of the following methods:

[0243] Method 1) determining the first area according to a predefined first position;

[0244] Method 2) determining, based on the received control instruction, a first region corresponding to the control instruction;

[0245] In some examples, this embodiment determines the second area by any of the following methods:

[0246] Method 3) determining the second area according to the position of the predefined second area;

[0247] Mode 4) determining, based on the received control instruction, a second region corresponding to the control instruction;

[0248] Method 5) Determine a second area corresponding to the first area based on the first area.

[0249] In some examples, the correspondence between the first area and the second area predefined in this embodiment includes but is not limited to any of the following: the positional relationship between the first area and the second area on the display area is axisymmetric or centrally symmetrical; the display area is Figure 4A When the area is divided into four equal parts, the first area is located at 400a, the second area is located at one of 401a, 402a, and 403a, or at least one area is set between the first area and the second area, that is, the second area is located at one of 402a and 403a; or the first area is located at 401a, the second area is located at one of 400a, 402a, and 403a; or the first area is located at 402a, the second area is located at one of 400a, 401a, and 403a; or the first area is located at 403a, the second area is located at one of 400a, 401a, and 402a; the display area is Figure 4BIn the embodiment, the first area is located at 402b, and the second area is located at one of 400b, 401b and 403b; or, the first area is located at 403b, and the second area is located at one of 400b, 401b and 402b. In order to facilitate user operation, the first area is generally set as an area close to the ground, but in the embodiment, the first area can also be set as 400b or 401b. If the first area is located at 400b, the second area is located at one of 401b, 402b and 403b. If the first area is located at 401b, the second area is located at one of 400b, 402b and 403b.

[0250] In the embodiment, the above-mentioned manner 1) to manner 2) for determining the first area and the above-mentioned manner 3) to manner 5) for determining the second area can be combined with each other. The following examples of combination are given in the embodiment.

[0251] Example 1): determining the first area according to a pre-defined first position, and determining the second area according to a pre-defined position of the second area.

[0252] In the embodiment, after the smart interactive panel is started, the first area is determined according to a pre-defined position of the first area on the smart interactive panel, and the second area is determined according to a pre-defined position of the second area on the smart interactive panel. In order to facilitate user operation on the smart interactive panel at a close distance, the first area can be determined according to a height range of the user, and the second area can be determined according to a comfort range of the smart interactive panel for long-distance viewing. For example, the position of the first area is determined to be within a range of 1m to 2m from the ground on the smart interactive panel, and the position of the second area is determined to be within a range of more than 2m from the ground on the smart interactive panel.

[0253] Example 2): determining the first area according to a pre-defined position of the first area, and determining the second area according to a received control instruction corresponding to the control instruction.

[0254] In the embodiment, the position of the first area on the smart interactive panel can be pre-determined, and the position of the second area can be determined by receiving a control instruction. Optionally, different control instructions correspond to the same second area, or different control instructions correspond to different second areas, which is not limited in the embodiment.

[0255] Example 3): determining the first area according to a received control instruction corresponding to the control instruction, and determining the second area according to a pre-defined position of the second area.

[0256] In implementation, the position of the second area on the smart interactive tablet can be predetermined, and the position of the first area can be determined by triggering the receipt of a control instruction. Optionally, different control instructions correspond to the same first area, or different control instructions correspond to different first areas. This embodiment does not impose too many restrictions on this.

[0257] Example 4) Based on a received control instruction, a first area corresponding to the control instruction is determined, and based on the first area, a second area corresponding to the first area is determined.

[0258] In implementation, the position of the first area on the smart interactive tablet can be determined by receiving a control instruction. Optionally, different control instructions correspond to the same first area, or different control instructions correspond to different first areas. This embodiment does not impose too many restrictions on this. The position of the second area on the smart interactive tablet can be determined based on the first area. After determining the first area, the second area corresponding to the first area can be determined based on the position of the first area on the smart tablet. In some examples, the position of the second area can be determined based on a predefined positional relationship between the first area and the second area. The positional relationship between the first area and the second area includes but is not limited to: axial symmetry, central symmetry, and adjacent. In this embodiment, if the display area is pressed Figure 4A The plurality of regions includes at least one other region between the first region and the second region. Optionally, the second region is located above, below, to the left, or to the right of the first region. This embodiment does not impose any restrictions on the positional relationship between the first region and the second region.

[0259] In some examples, the control instructions in this embodiment include, but are not limited to, any one or more of the following:

[0260] Touch operation instructions; instructions for the proximity sensor; instructions for the distance sensor; instructions for the Bluetooth receiver; instructions for the hotspot receiver; instructions for the WIFI receiver; instructions for peripheral devices that establish a communication connection with the smart interactive tablet. The touch operation instructions may be instructions received by the touch component, instructions for the proximity sensor and instructions for the distance sensor, which are used to represent instructions for detecting the position of a human body, that is, the distance between the human body and the smart interactive tablet can be measured according to the instructions; instructions for the Bluetooth receiver, instructions for the hotspot receiver, and instructions for the WIFI receiver are used to represent instructions sent by the terminal that establishes a communication connection with the smart interactive tablet; instructions for peripheral devices that establish a communication connection with the smart interactive tablet include but are not limited to instructions sent by a stylus pen and instructions sent by a remote control, such as clicking a shortcut button set on the stylus pen.

[0261] In some examples, the touch operation instructions of the user received by the first area in this embodiment include but are not limited to click instructions, writing instructions, and instructions sent by keys.

[0262] In some examples, this embodiment determines the first area according to the received control instruction. When the smart interactive tablet receives the control instruction, the first area is determined, which is specifically implemented in any of the following ways:

[0263] Method 1) If the control instruction is a received touch operation instruction for controlling the first area, determining the first area according to the position of the touch operation instruction in the display area;

[0264] In some examples, this embodiment specifically determines the first area according to the position of the touch operation instruction in any of the following ways:

[0265] Method 1a) If the touch operation instruction is a click operation instruction, obtaining a time difference between adjacent click operation instructions; if the time difference is less than a continuous click threshold, determining the first area based on the position of the most recently received click operation instruction in the display area;

[0266] In order to prevent the user from continuously clicking on the content in the first area, which may cause the display brightness of the first area to be unstable and flickering, this embodiment can determine the first area by detecting the last click operation instruction in the continuous touch operation instructions.

[0267] Mode 1b) If the touch operation instruction is a writing instruction, the first area is determined according to the position of the writing instruction in the display area.

[0268] During implementation, the first area can determine the first area at different positions as the writing instructions are different. If the position of the writing instruction keeps changing during the writing process, whether to update the position of the first area can be determined based on whether the range of change of the writing instruction exceeds a threshold. If the range of change of the writing instruction exceeds the threshold, the first area is updated based on the position of the latest writing instruction.

[0269] In some examples, this embodiment specifically determines the first area according to the position of the touch operation instruction in any of the following ways:

[0270] Mode 1c) taking the position of the touch operation instruction in the display area as the center, determining an area within a preset range as the first area;

[0271] The present embodiment does not impose too many restrictions on the shape of the first area. The area within the preset range is located in the display area.

[0272] Mode 1b) taking the position of the touch operation instruction in the display area as the center, determining a circular area with a field of view radius as the first area;

[0273] The field of view radius is determined according to the distance between the user who issues the touch operation instruction and the smart interactive tablet. Figure 6 As shown, the field of view radius is determined in the following way:

[0274] The human eye has approximately 124 degrees of visual acuity. When focused, the visual field is approximately one-fifth, or 25 degrees. The comfortable viewing range for a single eye is 60 degrees. A preliminary assumption is that when the user is at a distance S from the screen, the user's visually sensitive area is a 30-degree area around the central axis of their field of vision. The field of vision radius A can be calculated as S / √3, so the first area is a circle with the field of vision radius A as its radius.

[0275] It should be noted that, in this embodiment, method 1c)-1b) and method 1a)-1b) are two parallel schemes for determining the first area, wherein method 1a)-1b) is used to illustrate the method of determining the first area according to different touch operation instructions, and method 1c)-1b) is used to illustrate the method of specifically determining the first area according to the touch operation instruction. The two parallel schemes can be implemented in combination.

[0276] Method 2) If the control instruction is an instruction indicating that a human body position is detected, the first area is determined according to the human body position and the distance between the human body position and the smart interactive tablet.

[0277] In some examples, this implementation can be determined based on the distance between the user and the smart interactive tablet. The specific implementation steps are as follows:

[0278] Based on the human body position, the center of the area in the display area corresponding to the human body position is determined; and the first area is determined based on the area center. In some examples, the area center can be the position of the display area directly opposite the human face, or directly opposite the shoulder, or directly opposite the chest. This can be set according to user needs and is not limited in this embodiment. In implementation, the specific implementation method of determining the first area based on the area center is any of the following:

[0279] Mode 2a) Taking the center of the region as the center, an area within a preset range is determined as the first region;

[0280] Mode 2b) taking the center of the region as the center, determining a circular region with a field of view radius as the first region;

[0281] The field of view radius is determined according to the distance between the user who issues the touch operation instruction and the smart interactive tablet. Figure 6 As shown, the field of view radius is determined in the following way:

[0282] According to the human eye visual degree of about 124 degrees, when concentrating attention is about one-fifth, i.e. 25 degrees, the single eye comfortable visual field is 60 degrees, a preliminary setting can be made that when the user distance from the screen is S, the user visual sensitive area is the 30-degree area around the visual axis in the visual field. The visual field radius A can be calculated as Then the first area is a circle with the visual field radius A as the radius.

[0283] Mode 3) If the control instruction is an instruction other than a touch operation instruction and an instruction representing that a human body position is detected, the first area is determined according to a predefined position.

[0284] In some examples, the display brightness of the first area in the embodiment decreases as the distance between the human body position and the smart interactive panel decreases. Optionally, a multi-level dimming scheme can be provided in the embodiment, and the display brightness of the first area is controlled to decrease step by step as the human body is closer and closer to the smart interactive panel. In some examples, the step-by-step decreasing scheme provided in the embodiment is as follows:

[0285] If the distance between the human body position and the smart interactive panel is greater than an operation threshold and less than a viewing threshold, the display brightness of the first area is determined to be a first-level brightness, wherein the operation threshold is less than the viewing threshold; and if the distance between the human body position and the smart interactive panel is less than or equal to the operation threshold, the display brightness of the first area is controlled to be lower than the first-level brightness. In implementation, when the user is in a click operation state, the display brightness of the first area can be reduced, and when the user is in a writing operation, the display brightness of the first area can be reduced again. It should be noted that the two-level dimming scheme is only one example of the multi-level dimming scheme in the embodiment, and the multi-level dimming scheme based on the above principle also belongs to the protection scope of the disclosure.

[0286] In some examples, the area of the first area in the embodiment decreases as the distance between the human body position and the smart interactive panel decreases. It is easy to understand that when the user is in close operation, a smaller first area can be set to ensure that the user in operation can see more content other than the first area, thereby improving the viewing experience.

[0287] In some examples, the processor of the smart interactive panel in the embodiment is further configured to perform:

[0288] The touch operation instruction of the first area is received; and the touch operation instruction of the first area is converted into a touch operation instruction for controlling the second area. In implementation, when the user performs a touch operation in the first area, the second area can also be controlled to perform the touch operation, i.e. the touch operation instruction performed in the first area can be synchronized in the second area.

[0289] In some examples, to ensure that users who are watching from a distance can see the operations of the user who is operating the smart interactive tablet, this embodiment also provides a display mode for the second area, including but not limited to any of the following:

[0290] Mode 1) copying at least part of the content of the display area to the second area for display;

[0291] This embodiment can copy at least part of the content of the display area to the second area for display, so that users can operate in the first area without affecting users who are watching from a distance from the content of the display area.

[0292] Method 2) Copy at least part of the content of the first area to the second area for display.

[0293] This embodiment can control the second area to copy the content of the operation being performed in the first area. For example, the first area receives a click operation instruction to perform a click operation on an icon, and the icon and the click operation on the icon can be copied to the second area for display. Alternatively, the first area receives a writing instruction to perform a writing operation, and the writing instruction and the writing operation can be copied to the second area for display. That is, the content displayed in the first area can be copied to the second area, and according to the touch operation instruction of the first area, the corresponding operation is performed in the second area, so that users watching from a distance can watch the real-time operation content of the user operating the smart interactive tablet in real time.

[0294] In some examples, after copying at least part of the content in the first area to the second area for display, this embodiment may also determine whether the writing instruction in the first area has been completed. If the writing instruction in the first area is determined to be completed, the entire content in the second area is removed. Since a remote user does not need to continue viewing the written content after the user completes writing, the entire content in the second area may be removed after the writing in the first area is completed, thereby improving the user experience for users viewing the content from a distance.

[0295] In some examples, the display brightness of the second area can be set to be greater than the display brightness of other areas in the display area. Since the second area is provided for viewing by users at a distance, the display brightness of the second area can be set to the highest brightness in the display area to ensure a good viewing experience for users at a distance.

[0296] In some examples, the brightness of the display area in this embodiment can be set to multiple different brightness levels, where the display brightness of the first area is the lowest brightness and the display brightness of the second area is the highest brightness. If the display area includes other areas in addition to the first and second areas, the display brightness of the other areas is greater than the display brightness of the first area and less than the display brightness of the second area. Optionally, the display area also includes a third area, the display brightness of the second area is greater than the display brightness of the third area, and the display brightness of the third area is greater than the display brightness of the first area.

[0297] In some examples, this embodiment also provides a method for reducing the full-screen display brightness. Before determining the first area and the second area of ​​the display area of ​​the display screen, it is also used to receive a control instruction to reduce the display brightness of the full screen of the display screen. At this time, the brightness of the first area and the second area are both reduced to the minimum. If a touch operation instruction of the first area is received, the display brightness of the second area is increased, thereby achieving the effect of controlling the display brightness of the first area to be lower than the display brightness of the second area.

[0298] In some examples, this embodiment provides a method for display brightness restoration. The core idea is to control the display brightness of the first area to be lower than the display brightness of the second area, and then adjust the display brightness of the first area after the first area is displayed at the display brightness for a preset period of time. The specific adjustment methods include but are not limited to any of the following methods, as shown below:

[0299] Method 1) After determining that the operation of the first area ends for a preset period of time, adjusting the display brightness of the first area to a preset brightness;

[0300] In practice, the preset brightness is used to represent the default brightness set by the user, that is, the brightness is displayed according to the preset brightness after the device is turned on.

[0301] Method 2) after determining that the operation of the first area ends for a preset period of time, adjusting the display brightness of the first area to the display brightness of the previous preset period of time;

[0302] For example, the display brightness of the first area is L0. After controlling the display brightness of the first area to be lower than the display brightness of the second area, the display brightness of the first area is L1. After the first area is displayed at L1 for 10 minutes, the display brightness of the first area is adjusted to L0.

[0303] Mode 3) After determining that the operation of the first area ends for a preset period of time, the display brightness of the first area is adjusted to the same display brightness as that of the second area.

[0304] In some examples, this embodiment determines the preset brightness by any of the following methods:

[0305] Method 1: receiving a user image captured by a camera, and determining the preset brightness according to a pre-stored brightness requirement corresponding to the user image;

[0306] In this mode, the smart interactive tablet is equipped with a camera, which pre-sets and saves corresponding brightness requirements for different users through a face recognition algorithm, so that when each user is detected, personalized brightness can be provided for different users.

[0307] In practice, the smart interactive tablet is also equipped with a camera for capturing user images; the processor receives the user images captured by the camera and determines the preset brightness based on the brightness requirements corresponding to the user images. Different user images have different brightness requirements, which can provide a more personalized brightness setting method. In some examples, a face recognition algorithm can be used to store the personally set display brightness for users with specific brightness requirements, such as Figure 7 The specific implementation process is as follows:

[0308] Step 700: When the smart interactive tablet is powered on for the first time after installation, a prompt is displayed to set the brightness.

[0309] Step 701: Receive brightness requirements from a first user;

[0310] The brightness requirement includes but is not limited to a specific brightness value, or a brightness adjustment method, which includes but is not limited to the brightness adjustment method provided in this embodiment, or a method for adjusting the brightness according to the ambient brightness measured by a light detection sensor.

[0311] Step 702: Determine whether a global setting instruction has been received. If yes, proceed to step 703; otherwise, proceed to step 704.

[0312] Step 703: Set the brightness requirement as the brightness requirement corresponding to all users;

[0313] Step 704: Set the brightness requirement to the brightness requirement corresponding to the first user.

[0314] After setting the brightness requirements of multiple users using the above method, this embodiment uses a face recognition algorithm to use the user image captured by the camera on the smart interactive tablet to perform face recognition on the user image, and determines the brightness requirement of the user corresponding to the user image based on the recognition result, thereby setting the brightness of the smart interactive tablet.

[0315] Mode 2: In response to a brightness setting instruction from a user, determining the brightness corresponding to the setting instruction as the preset brightness;

[0316] Mode 3: receiving the ambient brightness measured by the light detection sensor, and determining the preset brightness according to a pre-stored brightness corresponding to the ambient brightness.

[0317] In some examples, this embodiment also provides a method for setting the display brightness of the eye protection mode, specifically including controlling the display brightness of the first area to be lower than the display brightness of the second area, receiving an eye protection instruction sent by a peripheral device that establishes a communication connection with the smart interactive tablet, and reducing the display brightness of the full screen of the display screen.

[0318] The embodiment of the present disclosure is based on the core idea of ​​controlling the brightness of the first area to be lower than the brightness of the second area, and adaptively adjusts the display brightness of the smart interactive flat panel, so that the viewing experience of users watching from a distance is not affected while users operating at a close distance can have a more comfortable operating experience. Based on this core idea, this embodiment provides multiple specific methods for adjusting the display brightness, which are specifically shown below.

[0319] Implementation 1: The positional relationship among the display area 800, the first area 801 and the second area 802 in this embodiment is as follows: Figure 8 As shown, the combination of the first area 801 and the second area 802 forms a display area 800. Figure 9 As shown, the specific implementation process of the first brightness adjustment method provided in this embodiment is as follows:

[0320] Step 900: Receive a user's touch operation instruction on the first area;

[0321] In implementation, the touch operation instruction may be a click of a shortcut button set on a stylus, or a click operation of an icon on a touch screen, or a touch gesture, used to determine the first area.

[0322] The content displayed in the first area includes at least a portion of the content in the display area. For example, the first area replicates all of the content or at least key elements of the display area. Key elements include, but are not limited to, program icons, tool icons for a program, and stylus icons for handwriting software. In a specific implementation, zooming is used to translate the content displayed in the display area to the first area for display, or only key content is displayed, for example, by omitting the background image of the display area and displaying only key program icons or tool icons.

[0323] Step 901: determining a corresponding first area according to the touch operation instruction;

[0324] Step 902: Determine that the second area is the remaining area in the display area except the first area;

[0325] Step 903: Control the display brightness of the first area to be lower than the display brightness of the second area.

[0326] During implementation, the user's operation in the first area can be mapped to the full screen. For example, when the user performs a text handwriting operation in the first area, the handwritten text is displayed in the first area and the second area at the same time, and the text displayed in the second area is a proportional enlargement of the text displayed in the first area.

[0327] This embodiment combines brightness adjustment with interactive control of a large-size display screen. The current 135-inch display screen is difficult to interact with in full screen due to its large size. Therefore, operations or handwriting can be performed through the first area, and the operation instructions or handwriting can also be displayed in the second area.

[0328] In some examples, a brightness adjustment option can also be displayed in the first area to provide brightness adjustment settings for users operating at close range. If the first area is currently in a handwriting interface, the handwriting background in the first area can be directly set to a low-brightness background or a brightness adjustment option can be provided in the first area. If the first area is an operation interface, such as a homepage, in addition to displaying operation icons, the homepage background can also be removed in the first area. In addition, the size and simplicity of the operation icons can also be adjusted.

[0329] Implementation 2: The positional relationship between the display area 1000, the first area 1001, and the second area 1002 in this embodiment is as follows: Figure 10 As shown, the combination of the first area 1001 and the second area 1002 forms a display area 1000. Figure 11 As shown, the specific implementation process of the second brightness adjustment method provided in this embodiment is as follows:

[0330] Step 1100: Receive a user's touch operation instruction on the first area;

[0331] Step 1101: determining a corresponding first area according to the touch operation instruction;

[0332] Step 1102: Determine a corresponding second area based on the first area;

[0333] Step 1103: Set the display brightness of the first area to the lowest brightness, and set the display brightness of the second area to the highest brightness.

[0334] In practice, the second area is used to copy the content of the first area, that is, the user's operation or writing in the first area can be copied to the second area. The second area can overlap with other areas to a certain extent, that is, the second area is floating on the upper layer of the display area.

[0335] Specifically, the full screen can form three areas. The first area 1001 is a low-brightness area where the user operates; the second area 1002 is a high-brightness area, and the content completely copies the content of the first area 1001, that is, the content written by the user in the first area 1001 is synchronously displayed in the second area 1002; the remaining area 1003 except the first area 1001 and the second area 1002 can adopt an intermediate brightness.

[0336] In some examples, after the user finishes writing, the content of the second area 1002 disappears, leaving only the first area 1001. In implementation, an animation effect can be set, such as the second area 1002 floating toward the first area 1001 until the two areas merge into one area.

[0337] In some examples, the display content of the remaining area 1003 may be scaled or translated to ensure that the first area 1001 does not block existing display elements.

[0338] Implementation 3: This embodiment provides a method for adjusting the display brightness according to the distance between the human body and the intelligent interactive tablet. Figure 12 The specific implementation process of this method is as follows:

[0339] Step 1200: receiving a control instruction, wherein the control instruction is used to indicate that a human body has been detected;

[0340] The control instruction includes but is not limited to one of a proximity sensor instruction, a distance sensor instruction and a touch operation instruction;

[0341] In this embodiment, it is possible to determine whether a human body is approaching the smart interactive tablet through a control instruction, and determine the position information of the human body relative to the smart interactive tablet according to the control instruction.

[0342] Step 1201: Determine the first area and the second area, and the distance between the human body and the intelligent interactive flat panel according to the control instruction;

[0343] In this embodiment, the distance between the human body and the smart interactive flat panel can be determined based on the received control instruction, and the brightness of the smart interactive flat panel can be adjusted based on the distance. The specific brightness adjustment method is as follows.

[0344] Step 1202: Control the display brightness of the first area to be lower than the display brightness of the second area according to a preset brightness level corresponding to the distance.

[0345] In some examples, the display brightness of the first area of ​​the smart interactive tablet is controlled to decrease as the distance decreases.

[0346] This embodiment pre-sets multiple brightness levels, so that the brightness of the smart interactive tablet can be adjusted according to the brightness level. In implementation, the higher the brightness level, the higher the corresponding brightness, and the lower the brightness level, the higher the corresponding brightness. This embodiment does not impose too many restrictions on the correspondence between brightness level and brightness.

[0347] In this embodiment, the brightness level corresponds to the distance between the human body and the intelligent interactive flat panel. As the distance decreases, the brightness level of the first area decreases, and the display brightness of the first area decreases accordingly. In some examples, as the distance decreases, the brightness level of the second area increases, and the display brightness of the second area increases accordingly. In some examples, as the distance decreases, the display brightness of the first area decreases, while the display brightness of the second area increases.

[0348] In some examples, the brightness level in this embodiment corresponds to the distance interval to which the human body is connected to the smart interactive flat panel. According to the brightness level corresponding to the distance interval to which the distance belongs, the display brightness of the first area is controlled to be lower than the brightness of the second area. In some embodiments, based on the above core concept, this embodiment provides a specifically implemented three-level dimming solution, which specifically includes the following dimming solutions:

[0349] Solution 12a: If the distance is not less than the viewing threshold, controlling the display brightness of the first area to be the same as the display brightness of the second area;

[0350] Optionally, the display brightness of the first area and the second area is controlled to be a preset brightness; the viewing threshold value set in this embodiment is used to characterize that the distance between the human body and the smart interactive flat panel is a long distance, and is suitable for the brightness value corresponding to long-distance viewing. Optionally, if the distance between the human body and the smart interactive flat panel is a long distance, the brightness of the smart interactive flat panel can be adjusted to a preset brightness. The preset brightness can be a brightness pre-set by the user, or it can be a brightness corresponding to the current environment obtained by automatic adjustment of a light detection sensor in the prior art. The above method in this example has already described various implementation methods for determining the preset brightness, which will not be repeated here.

[0351] Solution 12b: If the distance is greater than the operation threshold and less than the viewing threshold, the display brightness of the first area is controlled to be level one, and the display brightness of the second area is controlled to be a preset brightness;

[0352] The first level brightness is lower than the preset brightness; that is, the brightness of the smart interactive flat panel is controlled to be lower than the brightness of the second area;

[0353] Solution 12c: If the distance is not greater than the operation threshold, the display brightness of the first area is controlled to be the second level brightness, and the display brightness of the second area is controlled to be the preset brightness.

[0354] The secondary brightness is lower than the primary brightness.

[0355] This embodiment can detect in real time whether a person is approaching the smart interactive tablet based on the proximity sensor or distance sensor built into or external to the smart interactive tablet, and feed back the received instructions to the driving circuit of the smart interactive tablet in real time. When a person approaches the front of the smart interactive tablet, the feedback received from the proximity sensor is used to determine whether the person is approaching the smart interactive tablet. The straight-line distance S between the person and the smart interactive tablet can be set to S2. <S<S1时,确定当前用户有近距离使用需求,则通过驱动电路将第一区域的显示亮度降低为L1,第二区域的显示亮度设置为L0,其中L0为预置亮度,L1<L0。当人与智能交互平板的直线距离S为S<=S2时,确定当前用户有书写需求,则通过驱动电路将第一区域的显示亮度降低为L2,第二区域的显示亮度设置为L0,其中L2<L1。

[0356] In some examples, after controlling the display brightness of the first area for a preset period of time, this embodiment adjusts the display brightness of the first area based on the display brightness corresponding to the distance. For example, in this embodiment, after controlling the display brightness of the first area for a preset period of time, and determining that the current distance S between the human body and the smart interactive tablet is greater than or equal to S1, the brightness of the first area is restored to L0.

[0357] In summary, the adjustment method for adjusting the smart interactive tablet provided in this embodiment can effectively control the display brightness of the area where the user operates the smart interactive tablet to be lower than the display brightness of other areas, and provides multiple methods for determining the first area and the second area, as well as multiple methods for controlling the display brightness, so that when the user uses the smart interactive tablet at a close distance, the user experience is improved and the viewing experience of users watching from a distance is not affected.
