[0057] The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application. The terms used in the implementation method section of the embodiments of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0058] Figure 1 A schematic diagram of the process of the first temperature sensing method provided in the embodiment of the present application is shown as follows: Figure 1 As shown, the method comprises the following steps:

[0059] Step S110: Determine the ambient temperature of the image to be displayed.

[0060] Wearable display devices are display devices integrated into wearable devices, including but not limited to AR glasses, VR glasses or other wearable display devices. The picture to be displayed can be the next frame display picture of the current frame display picture, that is, the picture to be displayed can be the picture to be displayed soon.

[0061] See also Figure 2 , determining the ambient temperature of the picture to be displayed may include the following steps S111 to S113.

[0062] Step S111, obtaining voltage data of the picture to be displayed.

[0063] The voltage data of the picture to be displayed may include various data voltages corresponding to the picture to be displayed. Exemplarily, when displaying the picture, the display panel can use a row-by-row scanning to drive the gate lines to turn on in sequence, and output the data voltage through the data line to charge the pixel capacitor of each row. The data voltage is different, and the gray scale presented by the pixel is different. After all rows are charged, the display panel displays a complete frame of the image. In an embodiment of the present application, the next frame of video signal transmitted by the system on chip (System on Chip, SOC) can be received by a timing controller (TimerController, TCON). After receiving the next frame of video signal, the video signal is parsed to obtain the voltage data of the picture to be displayed.

[0064] The embodiment of the present application uses a timing controller to determine the ambient temperature of the picture to be displayed. In some embodiments, the timing controller can transmit the voltage data to the processor after obtaining the voltage data of the picture to be displayed, so as to reduce the workload of the timing controller.

[0065] Regarding the acquired voltage data of the picture to be displayed, the following is an exemplary description by taking the processor processing the voltage data of the picture to be displayed as an example.

[0066] Step S112: Match the voltage data of the picture to be displayed with the voltage data of various temperature pictures in the stored first corresponding relationship.

[0067] Before matching, a first correspondence between various temperature images and voltage data can be generated in advance, and the first correspondence can include a correspondence between the ambient temperature of the various temperature images and the voltage data. Exemplarily, images at different ambient temperatures and different images at the same ambient temperature can be displayed on a display device, and the ambient temperature and the corresponding voltage data can be recorded. It can be understood that the accuracy of the voltage data and the corresponding ambient temperature in the first correspondence can be gradually improved with the richness of the training data.

[0068] The ambient temperature of the picture can be determined by whether the environment in which the picture is displayed is "cold" or "hot". For example, when the ground is covered with snow, a white scene is formed on the ground, and the bottom of the picture is usually displayed in white. Therefore, the picture of ice and snow can be marked as cold 1, the picture of a large amount of snow is marked as cold 2, the picture of a small amount of snow is marked as cold 3, the picture of frost is marked as cold 1, the picture of heavy rain is marked as cold 2, the picture of the warm spring sun is marked as warm 1, the indoor picture is marked as warm 2, the natural picture under the sun is marked as hot 1, the picture of the scorching sun is marked as hot 2, etc. The specific picture markings can be divided according to actual needs, and each picture marking can also include multiple pictures. Among them, the pictures of cold 1, cold 2 and other marks can correspond to a temperature range or a specific temperature value respectively. The present application is described by taking each picture corresponding to a specific temperature value as an example.

[0069] When the display device displays different scene pictures, the voltage data corresponding to the scene pictures are recorded and stored, thereby generating a first corresponding relationship between the scene pictures and the voltage data corresponding to the scene pictures.

[0070] The storage location of the first correspondence relationship may be in the storage space of the processor itself, or in a memory external to the processor. The embodiment of the present application does not specifically limit the storage location of the first correspondence relationship.

[0071] After the voltage data of the picture to be displayed is acquired, the voltage data of the picture to be displayed may be matched with the stored voltage data line by line.

[0072] Step S113: determine the ambient temperature corresponding to the matched voltage data as the ambient temperature of the picture to be displayed.

[0073] When the matching degree (data overlap rate) between the voltage data of the screen to be displayed and the stored voltage data is greater than the target threshold, the ambient temperature corresponding to the matched voltage data can be determined as the ambient temperature of the screen to be displayed. The target threshold can be set to 70%, and the specific target threshold can be set according to actual needs, and the embodiment of the present application does not impose any special restrictions on this.

[0074] Considering that there may be multiple matched voltage data greater than the target threshold, the ambient temperature corresponding to the voltage data with the highest matching degree may be determined as the ambient temperature of the picture to be displayed.

[0075] Step S120: When there is a contact area between the wearable display device and the user's skin, output an electrical pulse signal corresponding to the ambient temperature to the contact area.

[0076] Considering that the wearable display device can contact the user's skin through a transmission medium to transmit an electrical pulse signal to the user, for example, the transmission medium can be an electronic skin. The electrical pulse signal can act on the user's nervous system through the electronic skin, causing the user to have a corresponding temperature perception.

[0077] Electronic skin is an ultra-thin electronic device that can produce touch. It is as soft as skin and can be attached to the surface of the human body. It senses changes in external parameters such as pressure and temperature, and transmits signals to the nervous system through circuits, thereby controlling the nervous system to produce a nearly real sense of touch, thereby enhancing the user's ability to interact with the environment or themselves.

[0078] like Figure 3 As shown, step S120 may include:

[0079] Step S121: determine a voltage signal corresponding to the ambient temperature according to the second corresponding relationship.

[0080] The human body has an important type of sensation called "warmth" and "coldness". According to the reaction characteristics of temperature receptors to dynamic stimuli, they can be divided into cold receptors and heat receptors. When temperature receptors sense changes in the environment, cold receptors and heat receptors can produce transient cold and hot sensations, and send neural electrical signals at the same time, which are transmitted through neurons to the central nervous system of the brain (referred to as the nervous system, including the brain and spinal cord) for integration, so that the human body produces corresponding cold and hot sensations. Different temperatures can produce different neural electrical signals.

[0081] In an embodiment of the present application, a neuron conduction detection instrument (equipment used in the biomedical field) can be used to observe the pulse signal waveform of the neuron conduction of the human body under different ambient temperatures, and simulate the magnitude of the current conducted. For example, the ambient temperature corresponding to the cold 1 screen can be -10°C, and the ambient temperature corresponding to the warm 1 screen can be 10°C. When the human body enters the warm 1 ambient temperature from the cold 1 ambient temperature, the temperature receptors of the human skin will continuously transmit the ambient temperature information (neural electrical signals) to the nervous system through neurons. After receiving the neural electrical signals, the nervous system determines that the ambient temperature of the human body has changed, and generates a control perception command to make the human body perceive the increase in ambient temperature. Therefore, the simulated current data can be measured by the neuron conduction detection instrument.

[0082] The voltage of the voltage signal can be obtained based on the current data and the impedance (the impedance of the neuron conduction detection instrument is known), thereby generating a second correspondence between the ambient temperature of the temperature screen and the voltage signal. After determining the ambient temperature of the screen to be displayed, the processor can determine the voltage signal corresponding to the ambient temperature based on the second correspondence and instruct the power supply circuit (Power IC) to generate a voltage signal.

[0083] The second correspondence relationship may be generated in advance and stored in the same location as the first correspondence relationship for easy retrieval. Of course, the second correspondence relationship may also be stored separately from the first correspondence relationship, and this application does not limit this.

[0084] Step S122: convert the determined voltage signal into an electrical pulse signal.

[0085] In order to allow the voltage signal to be received by the target nerve cell, the voltage signal can be processed to generate an electrical pulse signal. The target nerve cell is a cell that has a special protein that is sensitive to electric current and can absorb the electrical pulse signal and convert it into a neural electrical signal.

[0086] For example, as the current of the electric pulse signal increases, the frequency of the electric pulse will also increase accordingly. An operational amplifier (OP) can be used for OP amplification, and the amplification factor can be selected according to actual needs. Then, an oscillator can be used to change the signal amplitude to generate an electric pulse signal that can be received by the target nerve cells, so as to realize the conversion of digital signals into neural electrical signals, and then transmit them through nerve cells to finally reach the central nervous system of the brain.

[0087] It is understandable that the above-mentioned processing operation on the voltage signal may also include other processing methods, such as filtering, etc. In actual operation, the processing operation on the signal may be selected according to actual needs.

[0088] Step S123: outputting an electric pulse signal to the contact area.

[0089] After the determined voltage signal is converted into an electrical pulse signal, it can be output to the user through the electronic skin so that the user can perceive the corresponding temperature without the need for a temperature sensor. For example, when the user uses a wearable display device, the display screen switches from cold 1 to warm 1. The wearable display device generates an electrical pulse signal corresponding to the ambient temperature and transmits it to the target nerve cells through the electronic skin. The target nerve cells receive the electrical pulse signal and convert it into a neural electrical signal and then transmit it to the brain. After receiving the neural electrical signal, the brain determines that the ambient temperature of the user has changed and generates a control perception command to make the user perceive the increase in ambient temperature.

[0090] Taking into account the temperature diversity of the images to be displayed, when the ambient temperature of the images to be displayed is an extreme temperature (-30°C), if the user's nervous system is controlled for a long time to make it mistakenly believe that the user is under such a temperature when watching such images, it may have an impact on the user's health.

[0091] Figure 4This is a flow chart of the second temperature sensing method provided in the embodiment of the present application. Figure 4 , after step S110 and before step S120, the temperature sensing method may further include steps S210 to S230.

[0092] Step S210, determining whether the ambient temperature of the image to be displayed is lower than a first temperature threshold or higher than a second temperature threshold, if so, executing step S220.

[0093] The second temperature threshold may be higher than the first temperature threshold. For example, the first target threshold may be set to -5°C, and the second temperature threshold may be set to 40°C.

[0094] Step S220: performing temperature compensation on the ambient temperature of the image to be displayed.

[0095] Exemplarily, when the ambient temperature of the picture to be displayed is -20°C. In some embodiments, the ambient temperature of the picture to be displayed can be compensated to the first temperature threshold, that is, the compensated ambient temperature is -5°C. Similarly, when the ambient temperature value of the picture to be displayed is 50°C, the ambient temperature can be compensated to the second temperature threshold, that is, the compensated ambient temperature is 40°C.

[0096] In some other embodiments, when the ambient temperature value of the picture to be displayed is lower than the first temperature threshold, the ambient temperature can be increased by the first temperature. Taking the first temperature setting as 5°C as an example, the ambient temperature value of the picture to be displayed after compensation is -15°C. Similarly, when the ambient temperature value of the picture to be displayed is higher than the second temperature threshold, the ambient temperature is reduced by the second temperature. Taking the second temperature setting as 5°C as an example, the ambient temperature after compensation is 45°C.

[0097] In addition, when the ambient temperature of the image to be displayed is lower than the first temperature threshold, the temperature below the first temperature threshold can be reduced in proportion. For example, when the ambient temperature to be displayed is -20°C, which is 15°C lower than the first temperature threshold, it can be reduced in a ratio of 5:1, that is, when the ambient temperature of the image to be displayed decreases by 5°C, the ambient temperature corresponding to the output electrical pulse signal decreases by 1°C, and the compensated ambient temperature is -8°C.

[0098] Similarly, when the ambient temperature of the image to be displayed is higher than the second temperature threshold, the temperature value higher than the second temperature threshold can be reduced proportionally. For example, for every 5°C increase in the ambient temperature of the image to be displayed, the ambient temperature corresponding to the output electrical pulse signal increases by 1°C.

[0099] It can be understood that in actual operation, the first temperature threshold, the second temperature threshold, the first temperature, the second temperature and the ratio can be set as needed, and the embodiment of the present application does not impose any special restrictions on this.

[0100] Step S230: updating the ambient temperature of the image to be displayed to the compensated ambient temperature.

[0101] The compensated ambient temperature is determined as the final ambient temperature of the image to be displayed. The electronic skin can output an electrical pulse signal corresponding to the compensated temperature to the user, so that the user can have a good user experience while reducing the adverse effects of the ambient temperature change of the display image on the human body.

[0102] The embodiment of the present application provides a temperature sensing method, which includes: determining the ambient temperature of the image to be displayed; when there is a contact area between the wearable display device and the user's skin, outputting an electric pulse signal corresponding to the ambient temperature to the contact area. The technical solution provided by the present application can make the user feel the change of the ambient temperature when the ambient temperature in the display image changes, thereby improving the functional diversity of the wearable display device to better meet the user's usage needs.
