[0066] The features and exemplary embodiments of various aspects of this application will now be described in detail. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain this application and are not configured to limit this application. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples of this application.

[0067] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0068] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0069] Various modifications and variations can be made to this application without departing from its spirit or scope, which will be apparent to those skilled in the art. Therefore, this application is intended to cover modifications and variations falling within the scope of the corresponding claims (the claimed technical solutions) and their equivalents. It should be noted that the embodiments provided in this application can be combined with each other without contradiction.

[0070] Before describing the technical solutions provided in the embodiments of this application, in order to facilitate understanding of the embodiments of this application, this application first specifically explains the problems existing in the related technologies:

[0071] The related tactile display technology relies solely on changes in the height of tactile pixels to convey brightness information, and its one-dimensional information expression method is similar to that of early black and white display technology.

[0072] For example, related technologies arrange tactile display pixels into tactile graphics, text, or Braille by changing the mechanical or electromagnetic structure of each tactile pixel according to the signal from the signal source. These technologies only use the height of individual "tactile pixels" to represent the signal strength of a single pixel, similar to early display technologies that only had brightness levels and no color variations, known as "black and white displays."

[0073] Because the relevant technologies are limited to the single dimension of height adjustment, they cannot convey visual information other than brightness, resulting in insufficient information richness of tactile feedback. This makes it impossible to realize the multi-dimensional information expression in color visual display technology, to fully convey real image information, and to meet the tactile interaction needs in complex scenarios.

[0074] Based on this, embodiments of this application provide a touch display device, method, and apparatus that realize the leap of tactile information from a single dimension (height) to a dual dimension (height + temperature), improve the information dimension of tactile display, enhance the richness of information transmission, can more completely transmit real image information, and can meet the tactile interaction needs in complex scenarios.

[0075] The touch display device provided in the embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0076] Figure 1 This is a schematic diagram of the structure of a touch display device provided in an embodiment of this application, as shown below. Figure 1As shown, the touch display device 100 may include a signal conversion module 10, multiple height adjustment modules 20, and multiple temperature adjustment modules 30.

[0077] The signal conversion module 10 is used to convert the image signal into a height control signal and output it in response to the image signal, and to convert the image signal into a temperature control signal and output it. The height control signal includes multiple height control sub-signals, and the temperature control signal includes multiple temperature control sub-signals.

[0078] Specifically, the signal conversion module 10 is the information processing center of the touch display device 100, responsible for receiving image signals and converting them into height control signals and temperature control signals. The height control signal contains multiple height control sub-signals, and the temperature control signal contains multiple temperature control sub-signals, enabling subsequent height and temperature adjustments to be more precise and flexible.

[0079] The height adjustment module 20 corresponds one-to-one with the height control sub-signal. The height adjustment module 20 is used to adjust the height according to the corresponding height control sub-signal to achieve the target height, wherein the target height is used to represent the first type of visual information.

[0080] Specifically, each height adjustment module 20 corresponds one-to-one with a height control sub-signal, ensuring that each height adjustment module 20 receives its own dedicated height control sub-signal. Each height adjustment module 20 adjusts its height according to its corresponding height control sub-signal to achieve the desired target height. When a user touches the screen, they can perceive different height changes, which can represent changes in first-type visual information (such as brightness information).

[0081] The temperature adjustment module 30 corresponds one-to-one with the temperature control sub-signal. The temperature adjustment module 30 is used to adjust the temperature according to the corresponding temperature control sub-signal to achieve the target temperature, wherein the target temperature is used to represent the second type of visual information.

[0082] Specifically, each temperature adjustment module 30 corresponds one-to-one with a temperature control sub-signal, ensuring the accuracy of temperature adjustment. Each temperature adjustment module 30 can adjust the temperature according to the corresponding temperature control sub-signal to achieve the desired target temperature. When the user touches the device, they can feel different temperature changes, which can represent changes in a second type of visual information (such as color information).

[0083] According to the touch display device 100 provided in the embodiments of this application, the touch display device 100 includes a signal conversion module 10, a plurality of height adjustment modules 20, and a plurality of temperature adjustment modules 30. The signal conversion module 10 is used to convert an image signal into a height control signal and a temperature control signal in response to an image signal and output them, wherein the height control signal includes a plurality of height control sub-signals, and the temperature control signal includes a plurality of temperature control sub-signals. Each height adjustment module 20 corresponds one-to-one with a height control sub-signal, and is used to adjust the height according to the corresponding height control sub-signal to achieve a target height, where the target height represents a first type of visual information (such as brightness information). Each temperature adjustment module 30 corresponds one-to-one with a temperature control sub-signal, and is used to adjust the temperature according to the corresponding temperature control sub-signal to achieve a target temperature, where the target temperature represents a second type of visual information (such as color information). This application embodiment introduces a temperature adjustment module 30, which realizes the leap of tactile information from a single dimension (height) to a dual dimension (height + temperature), improves the information dimension of tactile display, enhances the richness of information transmission, can more completely transmit real image information, and can meet the tactile interaction needs in complex scenarios.

[0084] In some embodiments, the touch display area is divided into multiple first sub-display areas; each first sub-display area corresponds to a height adjustment module 20, and the height adjustment module 20 is located within the corresponding first sub-display area; the image signal includes first type sub-pixel values, second type sub-pixel values, and third type sub-pixel values ​​within the first sub-display area; the target height satisfies:

[0085] H = α × (R + G + B)

[0086] Where H, R, G, and B are the target height, first type of sub-pixel value, second type of sub-pixel value, and third type of sub-pixel value corresponding to the same first sub-display area, respectively, and α is a preset coefficient.

[0087] The first sub-display area is a height adjustment unit.

[0088] α is a pre-set coefficient that enables personalized display effects. The value of α can be flexibly adjusted according to different application scenarios and user needs. This application embodiment does not limit this.

[0089] Specifically, the touch display area is divided into multiple first sub-display areas, which are also divided into multiple height adjustment units. Each first sub-display area corresponds one-to-one with a height adjustment module 20, and the height adjustment module 20 is located within the corresponding first sub-display area. This ensures that the height adjustment module 20 can directly act on the corresponding display area, thus enabling independent height adjustment for different first sub-display areas, improving the accuracy and efficiency of the adjustment. Furthermore, the adjustability of the preset coefficient α allows the device to flexibly adjust the height adjustment strategy according to different application scenarios and user needs, achieving personalized display effects.

[0090] This embodiment divides the touch display area into multiple first sub-display areas, each serving as a height adjustment unit. Each first sub-display area corresponds one-to-one with a height adjustment module 20 located within it, enabling independent height adjustment for different first sub-display areas and significantly improving the accuracy and efficiency of the adjustment. The image signal contains the sub-pixel values ​​within each first sub-display area. Based on the target height formula H = α × (R + G + B), the required height adjustment for each height adjustment module 20 can be accurately calculated, further improving the accuracy and efficiency of the adjustment. Through the adjustability of the preset coefficient α, the height adjustment strategy can be flexibly adjusted according to different application scenarios and user needs, thereby presenting a personalized display effect and providing users with a personalized tactile experience.

[0091] In some embodiments, α is greater than 0 and less than or equal to 1.

[0092] In this embodiment, α being greater than 0 ensures a positive correlation between the target height H and the sum of sub-pixel values ​​(R+G+B), allowing height adjustment to reasonably change based on the sub-pixel values ​​of the image signal. This ensures that height adjustment is related to and logically consistent with the image display content. α being less than or equal to 1 acts as a limit, preventing excessive adjustment of the target height due to an excessively large sum of sub-pixel values. This avoids overly exaggerated height variations on the surface of the touch display device 100, maintaining the relative stability and rationality of the overall structure of the touch display device 100. It also ensures the harmony and comfort of the visual effect, allowing height adjustment to effectively enhance the tactile sense of depth without disrupting the overall tactile presentation due to over-adjustment.

[0093] In some embodiments, the first type of visual information is brightness information.

[0094] In this embodiment, the first type of visual information is determined to be brightness information, enabling the height adjustment module 20 to perform precise height adjustment based on the brightness differences of different areas of the image. A first sub-display area with higher brightness corresponds to a higher target height, and a first sub-display area with lower brightness corresponds to a lower target height, thereby creating a height variation on the surface of the touch display device 100 that matches the image brightness distribution, allowing the user to perceive changes in image brightness through touch.

[0095] It should be noted that the first type of visual information can also be other types of visual information besides brightness type information.

[0096] In some embodiments, the first sub-display area has N first-class sub-pixel values, N second-class sub-pixel values, and N third-class sub-pixel values, where N is an integer greater than or equal to 1.

[0097] Specifically, a height adjustment unit (first sub-display area) has N first-type sub-pixel values, N second-type sub-pixel values, and N third-type sub-pixel values. Since a first-type sub-pixel, a second-type sub-pixel, and a third-type sub-pixel can constitute a pixel, in other words, a height adjustment unit (first sub-display area) contains N pixels. Since a height adjustment unit (first sub-display area) corresponds to a height adjustment module, N pixels correspond to a height adjustment module 20.

[0098] In this embodiment, N pixels correspond to one height adjustment module 20. The value of N can be adjusted according to needs, which can ensure that the height of the first sub-display area is adjusted as a whole and reasonably based on the comprehensive information of multiple pixels in the first sub-display area, so as to achieve a layered three-dimensional tactile presentation. This avoids the high cost and complex design of equipping each pixel with a separate height adjustment module 20, and improves the tactile effect while taking into account the practicality and economy of the touch display device 100.

[0099] In some embodiments, N is 1.

[0100] Specifically, N=1 indicates that a height adjustment unit (first sub-display area) has a first type of sub-pixel value, a second type of sub-pixel value and a third type of sub-pixel value, that is, one pixel corresponds to one height adjustment module 20.

[0101] In this embodiment, height adjustment is precise down to a single pixel, greatly improving the fineness of height adjustment. The first type of visual information of each pixel can be independently presented through the corresponding height adjustment module 20, so that the first type of visual information of each pixel can be accurately reflected by height changes, presenting a realistic tactile effect, bringing a better tactile experience to the user, and is suitable for application scenarios with high requirements for image detail.

[0102] Figure 2-A This is a schematic diagram of the structure of a height adjustment module 20 in a touch display device 100 provided in an embodiment of this application.

[0103] In some embodiments, such as Figure 2-A As shown, the height adjustment module 20 may include an electrodeformation layer 21.

[0104] The electro-deformable layer 21 is used to deform according to the corresponding height control sub-signal to achieve the target height.

[0105] In this embodiment, the height adjustment module 20 includes an electro-deformable layer 21, which deforms according to a corresponding height control sub-signal to achieve a target height. The introduction of the electro-deformable layer 21 provides an efficient, precise, and flexible method for height adjustment. By receiving the height control sub-signal, the electro-deformable layer 21 can deform quickly and accurately, thereby achieving fine adjustment of the height of the corresponding position in the touch display area. The electro-deformable layer 21 is based on an electrical signal-controlled deformation mechanism, which not only has a fast response speed, enabling height adjustment to be completed in a short time to meet dynamically changing display requirements, but also high adjustment accuracy, precisely reaching the preset target height, ensuring the height adjustment effect, and improving the reliability and stability of the touch display device 100.

[0106] Figure 2-B This is another structural schematic diagram of the height adjustment module 20 in a touch display device 100 provided in this application embodiment.

[0107] In some embodiments, such as Figure 2-B As shown, the height adjustment module 20 may include an electro-deformable layer 21 and a support layer 22. The electro-deformable layer 21 is used to deform according to the corresponding height control sub-signal so that the electro-deformable layer 21 and the support layer 22 together reach the target height.

[0108] In this embodiment, the height adjustment module 20 consists of an electro-deformable layer 21 and a support layer 22. The electro-deformable layer 21 deforms according to the corresponding height control sub-signal, working together with the support layer 22 to reach the target height. The electro-deformable layer 21 has the ability to quickly respond to the height control sub-signal and achieve precise deformation, enabling the height adjustment module 20 to flexibly adapt to different target height requirements, achieve fine height adjustment, and thus more accurately present the stereoscopic effect of the image. However, the electro-deformable layer 21 may not be able to reach the target height on its own. At this time, the role of the support layer 22 becomes prominent. The support layer provides stable support for the entire height adjustment module 20 to flexibly adjust the height, making up for any shortcomings of the electro-deformable layer 21, and ensuring that the height adjustment module 20 can stably and reliably reach the target height under various conditions.

[0109] In some embodiments, the electrodeformation layer 21 is made of a piezoelectric ceramic material.

[0110] In this embodiment, the electro-deformable layer 21 is composed of piezoelectric ceramic material. Piezoelectric ceramic material possesses excellent electro-mechanical coupling characteristics, enabling deformation at lower voltages to achieve functions such as height adjustment. This prevents injury to personnel or damage to related equipment due to high voltage. When an electric field is applied, it can rapidly and accurately generate deformation, allowing the electro-deformable layer 21 to efficiently convert the height control sub-signal into mechanical deformation, thereby achieving fast and precise height adjustment. Furthermore, piezoelectric ceramic material has high response speed and sensitivity, completing the deformation process in a short time to meet dynamically changing display requirements and effectively improve the real-time performance of height adjustment. In addition, piezoelectric ceramic material also possesses good stability and repeatability, maintaining stable performance during multiple deformation processes, ensuring the accuracy and consistency of height adjustment, and providing a strong guarantee for the touch display device 100 to achieve high-quality and reliable touch effects.

[0111] In some embodiments, the piezoelectric ceramic material is a single crystal material of lead magnesium niobate-lead titanate.

[0112] In this embodiment, lead magnesium niobate-lead titanate (PMN-PT)[Pb(Mg1 / 3Nb2 / 3)O3](1-x)-[PbTiO3]x single crystal material is used as the piezoelectric ceramic material. PMN-PT single crystal material possesses characteristics such as high piezoelectric constant, large electromechanical coupling coefficient, high dielectric constant, and low loss, and its piezoelectric performance is approximately 10 times higher than that of ordinary piezoelectric materials. This allows the electrodeformation layer to generate a larger deformation amplitude when receiving a height control sub-signal, thereby achieving more precise and sensitive height adjustment. Furthermore, PMN-PT single crystal material also exhibits good stability and temperature characteristics, maintaining stable performance under different environmental conditions, ensuring the accuracy and reliability of height adjustment. Therefore, using PMN-PT single crystal material as the piezoelectric ceramic material can significantly improve the stereoscopic display effect and performance of touch display devices.

[0113] Figure 2-C This is another structural schematic diagram of the height adjustment module 20 in a touch display device 100 provided in this application embodiment.

[0114] In some embodiments, such as Figure 2-C As shown, the height adjustment module 20 includes an electromagnetic drive layer 23, an elastic layer 24, and a support layer 22 connected in sequence.

[0115] The electromagnetic drive layer 23 is used to generate a magnetic field according to the corresponding height control sub-signal, and the magnetic force of the magnetic field causes the magnetic elements in the support layer 22 to be displaced, so that the elastic layer 24 is deformed and the height adjustment module 20 reaches the target height.

[0116] In this embodiment, the height adjustment module 20 employs a design of an electromagnetic drive layer 23, an elastic layer 24, and a support layer 22 connected in sequence. The electromagnetic drive layer 23 generates a magnetic field based on a corresponding height control sub-signal. This magnetic force displaces the magnetic elements in the support layer 22, thereby deforming the elastic layer 24 to achieve the target height. The electromagnetic drive layer 23 is driven by an electric signal generating a magnetic field, resulting in a fast response time and rapid height adjustment based on the height control sub-signal. The elastic layer 24 provides greater buffering and flexibility during height adjustment, allowing for varying degrees of deformation based on the displacement of the magnetic elements. This enables precise height adjustment while absorbing and dispersing stress, protecting the entire module structure. The magnetic elements in the support layer 22, in conjunction with the electromagnetic drive layer 23, provide a stable and precisely controllable driving force for height adjustment, ensuring that the height adjustment module 20 can stably and accurately reach the target height. This effectively improves the accuracy, speed, and reliability of the touch display device 100 in height adjustment.

[0117] In some embodiments, the electromagnetic drive layer 23 includes an electromagnetic coil.

[0118] In this embodiment, the electromagnetic drive layer 23 includes an electromagnetic coil. The electromagnetic coil is a key component for generating a magnetic field; when current is applied, it can quickly and accurately generate a magnetic field of specific strength and direction. This allows the electromagnetic drive layer 23 to flexibly adjust the magnitude and direction of the magnetic field according to the corresponding height control sub-signal, thereby precisely controlling the magnetic force on the magnetic elements in the support layer 22. Because the magnitude and direction of the magnetic force can be precisely controlled, the displacement of the magnetic elements is more accurate, thus more accurately driving the elastic layer 24 to deform, enabling the height adjustment module 20 to stably and quickly reach the target height.

[0119] In some embodiments, the elastic layer 24 includes a spring.

[0120] In this embodiment, the elastic layer 24 is a spring. The spring has good elasticity and resilience, and when subjected to displacement by the magnetic element, it can deform quickly and accurately, providing flexible elastic support for the height adjustment module. This makes the height adjustment process smoother and more stable, effectively buffering the impact force caused by the displacement of the magnetic element and protecting the entire height adjustment module 20 structure from damage. Simultaneously, the spring's elastic coefficient is relatively stable, maintaining good performance under different environmental conditions, ensuring the accuracy and consistency of height adjustment. Moreover, the spring has a simple structure, low cost, and is easy to replace, reducing the production cost of the height adjustment module, facilitating later maintenance and upgrades, and contributing to improving the overall reliability and economy of the touch display device 100.

[0121] In some embodiments, the touch display device 100 further includes a height detection module 40; the height adjustment module 20 is used to adjust the height according to a corresponding height control sub-signal to achieve a target height, including:

[0122] The height adjustment module 20 is used to adjust the height according to the corresponding height control sub-signal to reach the first height;

[0123] The height detection module 40 is used to detect information about the first height, and when the absolute value of the height difference between the first height and the target height is greater than a preset threshold, it generates a target height control sub-signal based on the height difference.

[0124] The height adjustment module 20 is used to adjust the height according to the corresponding target height control sub-signal to reach the target height.

[0125] In this embodiment, the touch display device 100 is equipped with a height detection module 40. The height adjustment module 20 and the height detection module 40 work together to achieve precise height adjustment. The height adjustment module 20 first adjusts to a certain height based on the height control sub-signal, which can be called the first height. At this time, the height detection module 40 can accurately detect the information of the first height. If there is a height difference between the first height and the target height that exceeds a preset threshold, it means that the height adjustment module 20 needs to be controlled to further adjust the height to reach the target height. At this time, the height detection module 40 can generate a new height control sub-signal based on the height difference, which can be called the target height control sub-signal. The height adjustment module 20 then performs a second adjustment based on the target height control sub-signal, and finally accurately reaches the target height. Alternatively, if the height difference between the reached height and the target height is less than the preset threshold, it is also considered that the height adjustment module 20 has reached the target height. The closed-loop feedback adjustment mechanism of this embodiment makes the height adjustment more accurate and reliable, effectively avoiding adjustment deviations caused by various factors, ensuring that the touch display device 100 can stably and accurately present the required stereoscopic touch effect in different application scenarios, and improving the performance and user experience of the touch display device 100.

[0126] In some embodiments, the touch display area is divided into multiple second sub-display areas; the temperature adjustment module 30 corresponds one-to-one with the second sub-display area, and the temperature adjustment module 30 is located within the corresponding second sub-display area; the image signal includes first type sub-pixel values ​​and third type sub-pixel values ​​within the second sub-display area.

[0127] The target temperature meets the following requirements:

[0128] T = β(RB) / (R + B + ε)

[0129] Alternatively, the target temperature satisfies:

[0130] T = β(R / B) / (R+B+ε)

[0131] Where β is a preset coefficient, ε is a zero-prevention constant, and T, R, and B are the target temperature, first-class sub-pixel value, and third-class sub-pixel value corresponding to the same second sub-display area, respectively.

[0132] The second sub-display area is the temperature control unit.

[0133] It should be noted that, according to the "color temperature-hue" principle, the larger the RB or R / B value, the warmer the image hue; the smaller the RB or R / B value, the cooler the image hue. Therefore, the hue represented by the RB or R / B value can be used to represent the temperature that a temperature control unit should achieve.

[0134] In this embodiment, the touch display area is divided into multiple second sub-display areas, which are also divided into multiple temperature adjustment units. Each second sub-display area is equipped with a temperature adjustment module 30 located within it. The target temperature can be determined using the formula T = β(RB) / (R+B+ε) or T = β(R / B) / (R+B+ε). By dividing the area into second sub-display areas and equipping them with temperature adjustment modules 30, precise temperature control can be achieved at different locations within the touch display area, satisfying the differentiated tactile effects caused by different displayed content (such as different colors) in each area. When changes in image content cause changes in sub-pixel values, the target temperature can be automatically adjusted according to the target temperature formula, improving the touch effect and touch quality of the touch display device 100 and providing users with a better touch experience.

[0135] It should be noted that both the target temperature formulas T = β(RB) / (R+B+ε) and T = β(R / B) / (R+B+ε) can convert color information into temperature information. Because the two target temperature formulas have different sensitivities to changes in the first and third type of sub-pixel values, they can be applied to different types of image display scenarios.

[0136] In some embodiments, the second type of visual information is color information.

[0137] In this embodiment, the second type of visual information is determined as color information, so that the temperature adjustment module 30 can make precise temperature adjustment according to the color differences of each area of ​​the image, thereby forming a temperature change on the surface of the touch display device 100 that matches the color distribution of the image, allowing the user to perceive the change in image color through touch.

[0138] It should be noted that the second type of visual information can also be other types of visual information besides color type information.

[0139] In some embodiments, the second sub-display area has M first-class sub-pixel values, M second-class sub-pixel values, and M third-class sub-pixel values, where M is an integer greater than or equal to 1.

[0140] Specifically, a temperature adjustment unit (second sub-display area) has M first-type sub-pixel values, M second-type sub-pixel values, and M third-type sub-pixel values. Since a first-type sub-pixel, a second-type sub-pixel, and a third-type sub-pixel can constitute a pixel, in other words, a temperature adjustment unit (second sub-display area) contains M pixels. Since a temperature adjustment unit (second sub-display area) corresponds to a temperature adjustment module 30, M pixels correspond to a temperature adjustment module 30.

[0141] In this embodiment, M pixels correspond to one temperature adjustment module 30. The value of M can be adjusted according to needs, which can ensure that the temperature of the second sub-display area is adjusted in a comprehensive and reasonable manner based on the comprehensive information of multiple pixels in the second sub-display area, so as to realize the tactile presentation with temperature changes. This avoids the high cost and complex design of equipping each pixel with a separate temperature adjustment module 30, and improves the tactile effect while taking into account the practicality and economy of the touch display device 100.

[0142] In some embodiments, M is 1.

[0143] Specifically, M=1 indicates that a temperature adjustment unit (second sub-display area) has a first type of sub-pixel value, a second type of sub-pixel value and a third type of sub-pixel value, that is, one pixel corresponds to one temperature adjustment module 30.

[0144] In this embodiment, temperature adjustment is precise down to a single pixel, greatly improving the precision of temperature control. The second type of visual information for each pixel can be independently presented through the corresponding temperature adjustment module 30, thus accurately reflecting the second type of visual information (such as color information) of each pixel through temperature changes. This results in a realistic tactile effect, providing users with a better tactile experience. It achieves a leap from single-dimensional (height) to dual-dimensional (height + temperature) tactile information, enhancing the information dimension of tactile display and making it suitable for application scenarios with high image detail requirements.

[0145] Figure 3-A This is a schematic diagram of the structure of a temperature regulation module 20 in a touch display device 100 provided in this application embodiment.

[0146] In some embodiments, such as Figure 3-A As shown, the temperature regulation module 30 includes a temperature regulation layer 31; the temperature regulation layer 31 is used to regulate the temperature according to the corresponding temperature control sub-signal to achieve the target temperature.

[0147] In this embodiment, the temperature regulation module 30 includes a temperature regulation layer 31, which can regulate the temperature according to the corresponding temperature control sub-signal to achieve the target temperature. The temperature regulation layer 31 makes the temperature regulation process more direct and efficient, can quickly respond to the temperature control sub-signal, and accurately adjust the temperature to quickly reach the target temperature.

[0148] Figure 3-B This is another structural schematic diagram of the temperature adjustment module 20 in a touch display device 100 provided in this application embodiment.

[0149] In some embodiments, such as Figure 3-BAs shown, the temperature regulation module 30 includes a temperature regulation layer 31 and a heat-conducting layer 32; the temperature regulation layer 31 is used to regulate the temperature according to the corresponding temperature control sub-signal and then reach the target temperature through the heat-conducting layer 32.

[0150] In this embodiment, the temperature regulation module 30 includes a temperature regulation layer 31 and a heat-conducting layer 32. The temperature regulation layer 31 adjusts the temperature according to the corresponding temperature control sub-signal and then reaches the target temperature through the heat-conducting layer 32. The temperature regulation layer 31 can accurately respond to the temperature control sub-signal and quickly and effectively adjust its own temperature. The heat-conducting layer 32 plays a key role in efficiently transferring heat, and can evenly and quickly conduct the heat generated by the temperature regulation layer 31, ensuring that the temperature regulation unit (second sub-display area) can stably and quickly reach the target temperature, effectively improving the working stability and touch effect of the touch display device 100, and bringing a better user experience.

[0151] In some embodiments, the temperature regulating layer 31 includes a Peltier element.

[0152] In this embodiment, the temperature regulation layer 31 employs a Peltier element. The Peltier element possesses highly efficient thermoelectric conversion performance, enabling rapid and precise temperature changes based on the temperature control sub-signal, achieving rapid heating or cooling, thereby efficiently regulating the temperature of the temperature regulation unit (second sub-display area). The Peltier element is small and lightweight, facilitating integration into the temperature regulation layer and contributing to the slim and lightweight design of the touch display device 100. The Peltier element has a fast response speed, reaching the target temperature quickly, effectively reducing delays in the temperature regulation process. This ensures that the touch display device 100 stably and quickly presents the optimal temperature effect under different ambient temperatures, improving the overall performance and user experience of the touch display device 100. Furthermore, the miniature Peltier element can be driven by low voltage, preventing injury to personnel or damage to related equipment due to high pressure and high temperature.

[0153] In some embodiments, the thermally conductive layer 32 is made of graphene material.

[0154] In this embodiment, the heat-conducting layer 32 is made of graphene. Graphene has extremely excellent thermal conductivity, far exceeding that of many traditional materials. It can quickly and efficiently transfer the heat generated by the temperature regulation layer, enabling the touch display device 100 to achieve faster and more uniform heat conduction during temperature regulation. Simultaneously, graphene also possesses good flexibility and mechanical strength. When integrated into the heat-conducting layer, it ensures a tight fit with the temperature regulation layer and other components while remaining resistant to damage, thus improving the stability and reliability of the entire temperature regulation module 30. Furthermore, graphene is lightweight and thin, not significantly increasing the weight and volume of the touch display device 100, contributing to a thinner and lighter design and ultimately providing a better user experience.

[0155] It should be noted that, Figure 3-A and Figure 3-B In this configuration, the height adjustment unit (first sub-display area) and the temperature adjustment unit (second sub-display area) are identical, i.e., M = N. For example, if M = N = 1, then one pixel corresponds to one height adjustment module 20 and one temperature adjustment module 30. Therefore, the temperature adjustment module 30 can be located above the height adjustment module 20. When the size of the temperature adjustment module 30 is limited (e.g., the Peltier element is large), one temperature adjustment module 30 can correspond to multiple height adjustment modules 20, meaning the area of ​​the temperature adjustment unit (second sub-display area) is larger than that of the height adjustment unit (first sub-display area).

[0156] For example, such as Figure 3-C As shown, the height adjustment unit (first sub-display area) and the temperature adjustment unit (second sub-display area) are different, with N=1 and M=3. One pixel corresponds to one height adjustment module 20, and three pixels correspond to one height adjustment module 20. That is, one temperature adjustment module 30 can correspond to three height adjustment modules 20. Therefore, when the size of the temperature adjustment module 30 is limited (such as when the Peltier element is large), by having one temperature adjustment module 30 correspond to multiple height adjustment modules 20, a higher degree of integration can be achieved in a limited space, effectively reducing production costs and energy consumption, while improving the efficiency and stability of temperature adjustment, making the equipment layout more flexible.

[0157] It should be noted that, in Figure 3-C In this system, since the height adjustment unit (first sub-display area) and the temperature adjustment unit (second sub-display area) are different, the temperature adjustment module 30 can be located on the side of the height adjustment module 20. The temperature adjustment module 30 may include a temperature adjustment layer 31 and a heat-conducting layer 32. The height adjustment module 20 may include an electrodeformation layer 21 and a support layer 22. The support layer 22 has thermal conductivity. The temperature adjustment layer 31 transfers temperature to the support layer 22 through the heat-conducting layer 32, and then the support layer transfers the temperature to the contact surface.

[0158] For example, such as Figure 4 As shown, the height adjustment unit (first sub-display area) and the temperature adjustment unit (second sub-display area) are different. One pixel in the touch display area corresponds to one height adjustment unit (first sub-display area), and the touch display area is divided into four temperature adjustment units (second sub-display areas). It should be noted that the division of the temperature adjustment units (second sub-display areas) can be flexibly adjusted according to actual needs to achieve optimal performance and layout, and this embodiment does not limit this.

[0159] In some embodiments, the touch display device 100 may further include a temperature detection module 50; the temperature adjustment module 30 is used to adjust the temperature according to a corresponding temperature control sub-signal to achieve a target temperature, including:

[0160] Temperature regulation module 30 is used to adjust the temperature according to the corresponding temperature control sub-signal to reach the first temperature;

[0161] The temperature detection module 50 is used to detect information about the first temperature, and when the absolute value of the temperature difference between the first temperature and the target temperature is greater than a preset threshold, it generates a target temperature control sub-signal based on the temperature difference.

[0162] The temperature regulation module 30 is used to adjust the temperature according to the corresponding target temperature control sub-signal to achieve the target temperature.

[0163] In this embodiment, the touch display device 100 is equipped with a temperature detection module 50. The temperature adjustment module 30 first adjusts to a certain temperature based on a temperature control sub-signal, which can be called a first temperature. Then, the temperature detection module 50 detects the first temperature information. If the absolute value of the temperature difference between the first temperature and the target temperature is greater than a preset threshold, a new temperature control sub-signal is generated based on the temperature difference. This new temperature control sub-signal can be called a target temperature control sub-signal. The temperature adjustment module 30 then adjusts to the target temperature based on the target temperature control sub-signal. The addition of the temperature detection module 50 forms a closed-loop feedback adjustment mechanism, which can monitor the temperature adjustment effect in real time and accurately. When the initial adjustment fails to reach the target temperature, a new target temperature control sub-signal can be quickly generated based on the detected temperature difference, allowing the temperature adjustment module 30 to make targeted adjustments until the target temperature is accurately reached. Alternatively, if the temperature difference between the reached temperature and the target temperature is less than a preset threshold, the temperature adjustment module 30 is also considered to have reached the target temperature. This improves the touch effect and user experience of the touch display device 100 and ensures that the touch display device 100 can work stably and reliably in different environments.

[0164] Figure 5 This is a flowchart illustrating a touch display method provided in an embodiment of this application.

[0166] S110, the control signal conversion module 10 responds to the image signal by converting the image signal into a height control signal and outputting it, and converting the image signal into a temperature control signal and outputting it.

[0175] In this embodiment, the height adjustment module 20 first adjusts to a first height based on the height control sub-signal. At this time, the height detection module 40 can accurately detect the information of the first height. If there is a height difference between the first height and the target height that exceeds a preset threshold, it indicates that the height adjustment module 20 needs to be further adjusted to reach the target height. At this time, the height detection module 40 can generate a new target height control sub-signal based on the height difference. The height adjustment module 20 then performs a second adjustment based on the target height control sub-signal, and finally accurately reaches the target height. Alternatively, if the height difference between the reached height and the target height is less than the preset threshold, it is also considered that the height adjustment module 20 has reached the target height. The closed-loop feedback adjustment mechanism of this embodiment makes the height adjustment more accurate and reliable, effectively avoiding adjustment deviations caused by various factors, ensuring that the touch display device 100 can stably and accurately present the required stereoscopic touch effect in different application scenarios, and improving the performance and user experience of the touch display device 100.

[0176] Figure 7 This is a flowchart illustrating a touch display method provided in an embodiment of this application.

[0177] In some embodiments, such as Figure 7 As shown, the touch display device 100 may also include a temperature detection module 50; step S130 controls the temperature adjustment module 30 to adjust the temperature according to the corresponding temperature control sub-signal to achieve the target temperature, and may include steps S131 to S133.

[0178] S131, the temperature regulation module adjusts the temperature according to the corresponding temperature control sub-signal to reach the first temperature.

[0179] S132, the control temperature detection module detects the information of the first temperature, and when the absolute value of the temperature difference between the first temperature and the target temperature is greater than a preset threshold, it generates a target temperature control sub-signal based on the temperature difference.

[0180] S133, the temperature regulation module adjusts the temperature according to the corresponding target temperature control sub-signal to reach the target temperature.

[0181] In this embodiment, the temperature adjustment module 30 first adjusts to a first temperature based on a temperature control sub-signal. Then, the temperature detection module 50 detects this first temperature information. If the absolute value of the temperature difference between the first temperature and the target temperature is greater than a preset threshold, a new target temperature control sub-signal is generated based on the temperature difference. The temperature adjustment module 30 then adjusts to the target temperature based on the target temperature control sub-signal. The addition of the temperature detection module 50 forms a closed-loop feedback adjustment mechanism, which can monitor the temperature adjustment effect in real time and accurately. When the initial adjustment fails to reach the target temperature, a new target temperature control sub-signal can be quickly generated based on the detected temperature difference, allowing the temperature adjustment module 30 to make targeted adjustments until the target temperature is accurately reached. Alternatively, if the temperature difference between the reached temperature and the target temperature is less than a preset threshold, the temperature adjustment module 30 is also considered to have reached the target temperature. This improves the touch effect and user experience of the touch display device 100 and ensures that the touch display device 100 can work stably and reliably in different environments.
