[0080] The following details the specific implementation manners of the present disclosure with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only for the purpose of illustrating and explaining the present disclosure, and are not used to limit the present disclosure.

[0081] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0082] Unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present disclosure should have the ordinary meanings understood by those of ordinary skill in the art to which the present disclosure pertains. The "first", "second" and similar terms used in the present disclosure do not denote any order, quantity or importance, but are only used to distinguish different components. Similarly, words such as "comprising" or "including" mean that the elements or objects appearing before this word cover the elements or objects listed after this word and their equivalents, without excluding other elements or objects. The terms "connected" or "coupled" and the like are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. The terms "upper", "lower", "left", "right", etc. are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0083] As used herein, "parallel" and "perpendicular" include the stated situations and situations similar to the stated situations, and the range of such similar situations is within an acceptable deviation range, where the acceptable deviation range is determined by those of ordinary skill in the art considering the measurements being discussed and the errors associated with the measurements of specific quantities (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, where the acceptable deviation range for approximate parallelism may be, for example, within 5° deviation; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, where the acceptable deviation range for approximate perpendicularity may also be, for example, within 5° deviation.

[0084] It should be understood that when a layer or element is referred to as being on another layer or substrate, it may be that the layer or element is directly on the other layer or substrate, or there may be an intermediate layer between the layer or element and the other layer or substrate.

[0085] Exemplary embodiments are described herein with reference to cross-sectional views and / or plan views that are idealized exemplary drawings. In the drawings, the thickness of layers and regions is exaggerated for clarity. Thus, variations in the shape relative to the drawings due to, for example, manufacturing techniques and / or tolerances are contemplated. Accordingly, the exemplary embodiments should not be construed as being limited to the shapes of the regions shown herein, but include shape deviations caused, for example, by manufacturing. Thus, the regions shown in the drawings are schematic in nature, and their shapes are not intended to show the actual shape of the regions of the device and are not intended to limit the scope of the exemplary embodiments.

[0086] Figure 1 It is a schematic diagram of the module structure of the display device provided in some embodiments of the present disclosure. As Figure 1 shown, the display device 10 includes: a display module 13, at least one sensor module 101, and a controller 12.

[0087] Among them, the sensor module 101 is configured to generate a detection signal and output the detection signal to the controller 12. For example, each sensor module 101 can generate a detection signal according to the information to be detected in the external environment. The information to be detected in the external environment may include: environmental information of the external natural environment, such as information on the brightness, temperature, humidity, noise, etc. of the external environment; it may also include information on surrounding users, such as whether there are users around, whether a user inputs an instruction to the display device 10, and so on.

[0088] Among them, the detection signal of each sensor module 101 corresponds to a signal identification range. In addition, each sensor module can correspond to a control instruction of the controller 12.

[0089] The controller 12 is configured to detect the duration of the valid edge in the received signal and determine whether the duration is within at least one signal identification range. If the duration is within at least one of the signal identification ranges, a corresponding control instruction is issued.

[0090] It should be noted that the valid edge is a rising edge or a falling edge. Figure 2 This is a waveform schematic diagram of the signal provided in some embodiments of the present disclosure. Figure 3 is Figure 2 the relationship curve of the voltage and time of the signal shown. As Figure 2 and Figure 3 shown, the duration of the rising edge in the signal refers to the time elapsed from the bottom position to the top position of the rising edge in the waveform of the signal; that is, Figure 2 and Figure 3 the t2 shown in; similarly, the duration of the falling edge in the signal refers to the time elapsed from the top position to the bottom position of the falling edge in the waveform of the signal; that is, Figure 2 and Figure 3 the t1 shown in.

[0091] For the controller 12, the signal it receives may be the detection signal output by one of the sensor modules 11, or it may be the signal output by other modules. In the embodiments of the present disclosure, when the data interface of the controller 12 receives a signal, the controller 12 not only detects the valid edge in the received signal, but also detects the duration of the valid edge. When the duration is within the signal identification range corresponding to the i-th sensor module 101, the controller 12 can determine that the signal it receives is the detection signal sent by the i-th sensor module 101, and thus can issue a control instruction corresponding to the i-th sensor module 101. By detecting the duration of the valid edge further when detecting the valid edge, the controller 12 can improve the recognition accuracy.

[0092] In some embodiments, there are multiple sensor modules 101, and the detection signals of different sensor modules 101 correspond to different signal identification ranges. Among them, different sensor modules 101 correspond to different control instructions.

[0093] In addition, multiple sensor modules 101 are configured to transmit signals to the same data port of the controller 12. Among them, this data port can be an I2C (Inter-Integrated Circuit) interface. In this case, the signals received by the data port include a clock signal and a data signal. When the controller 12 detects the duration of the valid edge in the received signal, specifically, it detects the duration of the valid edge in the data signal received by the data port.

[0094] Among them, the data port includes a data receiving end and a clock receiving end. The data receiving end is used to receive the data signal, and the clock receiving end is used to receive the clock signal. In an example, the period of the clock signal is less than the period of the data signal; and the period of the clock signal is fixed. The controller 12 can determine the duration of the valid edge according to the period of the clock signal occupied by the valid edge. For example, when the controller 12 receives the high level of the n1th clock signal, the valid edge in the data signal is at the starting moment; when the controller 12 receives the high level of the n2th clock signal, the valid edge in the data signal is at the termination moment, then the duration of the valid edge is (n2 - n1) * the period of the clock signal.

[0095] In the embodiments of the present disclosure, the controller 12 can monitor the duration of the rising edge in the received signal and issue a corresponding control instruction when the duration of the rising edge is within the corresponding signal identification range; or it can monitor the duration of the falling edge in the received signal and issue a corresponding control instruction when the duration of the falling edge is within the corresponding signal identification range; or it can monitor the duration of the rising edge and the duration of the falling edge at the same time and issue a corresponding control instruction when the duration of the rising edge and the duration of the falling edge are respectively within their corresponding signal identification ranges, so that when the number of sensor modules 101 is relatively large, these sensor modules 101 can be monitored simultaneously.

[0096] Specifically, in some embodiments, the above signal identification range is the rising edge duration range; in this case, the controller 12 is specifically configured to detect the duration of the rising edge in the received signal and determine whether the duration is within the rising edge duration range. If the duration is within the rising edge duration range, a corresponding control instruction is issued.

[0097] In some other embodiments, the above signal identification range is a falling edge duration range; in this case, the controller 12 is specifically configured to detect the duration of the falling edge in the received signal, and determine whether the duration is within the falling edge duration range. If the duration is within the falling edge duration range, a corresponding control instruction is issued.

[0098] In still some other embodiments, the signal identification range is a rising edge duration range and a falling edge duration range. In this case, the controller 12 is specifically configured to detect the durations of the rising edge and the falling edge in the received signal, and determine whether the durations of the rising edge and the falling edge are respectively within the rising edge duration range and the falling edge duration range. If the durations of the rising edge and the falling edge are respectively within the rising edge and the falling edge duration ranges, a corresponding control instruction is issued.

[0099] Taking the sensor module 101 in the display device 10 including a first sensor module 11 and a second sensor module 15 as an example below, the specific functions of the controller 12 will be described.

[0100] In the first example, the first sensor module 11 corresponds to a first signal identification range, and the second sensor module 13 corresponds to a second signal identification range; the first signal identification range is a first rising edge duration range, and the second signal identification range is a second rising edge duration range. In this case, the controller 12 can be specifically configured to detect the duration of the rising edge in the received signal, and determine whether the duration of the rising edge is within the first rising edge duration range. If the duration is within the first rising edge duration range, a corresponding control instruction is issued in response to the first sensor module 11; and, determine whether the duration of the rising edge is within the second rising edge duration range. If the duration is within the second rising edge duration range, a corresponding control instruction is issued in response to the second sensor module 15.

[0101] Among them, in the embodiments of the present disclosure, there is a preset mapping relationship between each sensor module 11 and the control instruction of the controller 12; "issuing a corresponding control instruction in response to the first sensor module 11", that is, issuing a control instruction corresponding to the first sensor module 11; "issuing a corresponding control instruction in response to the second sensor module 15", that is, issuing a control instruction corresponding to the second sensor module 15.

[0102] Among them, after the controller 12 determines the duration of the rising edge, it can first compare the duration with one of the first rising edge duration range and the second rising edge duration range. If it is within one of the ranges, it will no longer be compared with the other; of course, it can also compare the duration of the rising edge with the two time ranges twice.

[0103] In the second example, the first sensor module 11 corresponds to a first signal identification range, and the second sensor module 13 corresponds to a second signal identification range; the first signal identification range is a first falling edge duration range, and the second signal identification range is a second falling edge duration range. In this case, the controller 12 may specifically be configured to detect the duration of the falling edge in the received signal, and determine whether the duration of the falling edge is within the first falling edge duration range. If the duration of the falling edge is within the first falling edge duration range, then in response to the first sensor module 11, corresponding control instructions are issued; and, determine whether the duration of the falling edge is within the second falling edge duration range. If the duration of the falling edge is within the second falling edge duration range, then in response to the second sensor module 15, corresponding control instructions are issued.

[0104] Wherein, after the controller 12 determines the duration of the falling edge, it may first compare the duration with one of the first falling edge duration range and the second falling edge duration range. If it is within one of the ranges, then it will not compare with the other; of course, it may also compare the duration of the falling edge with the two time ranges twice.

[0105] In the above first example and second example, the controller 12 monitors the rising edge duration in the signal it receives. When the rising edge duration is within the rising edge time range corresponding to the first sensor module 11, then the controller 12 determines that the signal received is the signal emitted by the first sensor module 11; when the rising edge duration is within the rising edge time range corresponding to the second sensor module 15, then the controller 12 determines that the signal received is the signal emitted by the second sensor module 15. Alternatively, the controller 12 monitors the falling edge duration in the signal it receives. When the falling edge duration is within the falling edge time range corresponding to the first sensor module 11, then the controller 12 determines that the signal received is the signal emitted by the first sensor module 11; when the falling edge duration is within the falling edge time range corresponding to the second sensor module 15, then the controller 12 determines that the signal received is the signal emitted by the second sensor module 15.

[0106] In the third example, the first sensor module 11 corresponds to a first signal identification range, and the second sensor module 15 corresponds to a second signal identification range; the first signal identification range is a first rising edge duration range, and the second signal identification range is a second falling edge duration range. In this case, the controller 12 is specifically configured to detect the duration of the rising edge in the received signal and determine whether the duration is within the first rising edge duration range. If the duration is within the first rising edge duration range, a corresponding control instruction is issued in response to the first sensor module 11; and, to detect the duration of the falling edge in the received signal and determine whether the duration is within the second falling edge duration range. If the duration is within the second falling edge duration range, a corresponding control instruction is issued in response to the second sensor module 15.

[0107] In this example, when the controller 12 detects that the rising edge duration in the received signal is within the first rising edge duration range, it is determined that the received signal is the detection signal generated by the first sensor module 11; when the controller 12 detects that the falling edge duration in the received signal is within the second falling edge duration range, it is determined that the received signal is the detection signal generated by the second sensor module 15, so that the source of the received signal can be distinguished.

[0108] For example, when the controller 12 first receives the rising edge of the signal, it detects the duration of the rising edge and determines whether the duration is within the first rising edge duration range. If so, it is determined that the received signal is the detection signal generated by the first sensor module 11 and a corresponding control instruction is issued; at this time, the duration of the falling edge may no longer be detected. If the duration of the rising edge is not within the first rising edge duration range, the duration of the falling edge is continuously detected.

[0109] When the controller 12 first receives the falling edge of the signal, it detects the duration of the falling edge and determines whether the duration is within the second falling edge duration range. If so, it is determined that the received signal is the detection signal generated by the second sensor module 15 and a corresponding control instruction is issued; at this time, the duration of the rising edge may no longer be detected. If the duration of the falling edge is not within the second falling edge duration range, the duration of the rising edge is continuously detected.

[0110] In the fourth example, the first sensor module 11 corresponds to a first signal identification range, and the second sensor module 15 corresponds to a second signal identification range. The first signal identification range is a first rising edge duration range, and the second signal identification range is a second rising edge duration range and a second falling edge duration range. In this case, the controller 12 is specifically configured to detect the duration of the rising edge in the received signal and determine whether the duration is within the first rising edge duration range. If the duration is within the first rising edge duration range, a corresponding control instruction is issued in response to the first sensor module 11; and to detect the durations of the rising edge and the falling edge in the received signal and determine whether the durations of the rising edge and the falling edge are respectively within the second rising edge duration range and the second falling edge duration range. If the durations of the rising edge and the falling edge are respectively within the second rising edge duration range and the second falling edge duration range, a corresponding control instruction is issued in response to the second sensor module 15.

[0111] In the fourth example, for example, when the controller 12 determines whether the received signal is from the first sensor module 11, it can monitor only the duration of the rising edge in the received signal. If the duration of the rising edge is within the first rising edge duration range, it is determined that the received signal is from the first sensor module 11; otherwise, it is determined that the received signal is not from the first sensor module 11. When the controller 12 determines whether the received signal is from the second sensor module 15, it needs to monitor the durations of the rising edge and the falling edge respectively. If the duration of the rising edge is within the second rising edge duration range and the duration of the falling edge is within the second falling edge duration range, it is determined that the received signal is from the second sensor module 15; otherwise, it can be determined that the received signal is not from the second sensor module 15. In this case, the rising edge duration range and the falling edge duration range corresponding to each sensor module do not need to be set too small, thereby improving the design flexibility.

[0112] For example, after the controller 12 receives a signal, it detects the duration of the rising edge in the signal. If the duration of the rising edge is within the first rising edge duration range, a control instruction corresponding to the first sensor module 11 is issued; at this time, the duration of the falling edge does not need to be detected. If the duration of the rising edge is not within the first rising edge duration range, the duration of the falling edge can be detected, and it is determined whether the durations of the rising edge and the falling edge are respectively within the second rising edge duration range and the second falling edge duration range. If they are respectively within the second rising edge duration range and the second falling edge duration range, a control instruction corresponding to the second sensor module 15 is issued.

[0113] In the fifth example, the first sensor module 11 corresponds to a first signal identification range, and the second sensor module 15 corresponds to a second signal identification range. The first signal identification range is a first falling-edge duration range, and the second signal identification range is a second rising-edge duration range and a second falling-edge duration range. In this case, the controller 12 is specifically configured to detect the duration of the falling edge in the received signal and determine whether the duration is within the first falling-edge duration range. If the duration is within the first falling-edge duration range, a corresponding control instruction is issued in response to the first sensor module 11; and to detect the duration of the rising edge and the duration of the falling edge in the received signal and determine whether the duration of the rising edge and the duration of the falling edge are respectively within the second rising-edge duration range and the second falling-edge duration range. If the duration of the rising edge and the duration of the falling edge are respectively within the second rising-edge duration range and the second falling-edge duration range, a corresponding control instruction is issued in response to the second sensor module 15.

[0114] The judgment principle of the fifth example is similar to that of the fourth example, and will not be elaborated here.

[0115] In some embodiments, at least one sensor module 101 in the display device 10 includes: a first sensor module 11, which is configured to detect whether a user leaves a preset area on the display side of the display module 13, and generate and output a first detection signal when it detects that the user leaves the preset area.

[0116] Wherein, the controller 12 is specifically configured to, when it is determined that the duration of the valid edge of the received signal is within the signal identification range corresponding to the first detection signal, it can be determined that the user has left the above preset area. At this time, the display module 13 can output a first control instruction to control the display module 13 to complete a first operation; and / or output a second control instruction to the host-side circuit board 20 to control the host-side circuit board 20 to complete a second operation. Wherein, the first operation is to turn off the display module 13 or put the display module 13 on standby; the second operation is to turn off the host or put the host on standby, thereby reducing power consumption.

[0117] Wherein, the host-side circuit board 20 specifically refers to the system main board provided on the host side. In the case where the first sensor module 11 does not generate a first detection signal, the host-side circuit board 20 can provide a driving signal to the controller 12 in the display device 10 according to the image information of the image source and the instructions input by the user (such as instructions input through a mouse or keyboard), and the controller 12 drives the display module 13 to display according to the driving signal.

[0118] Among them, the host circuit board 20 can be communicatively connected to the controller 12 through the I2C interface. The controller 12 can be connected to the display module 13 through the LVDS interface, the EDP interface, and the VBO interface.

[0119] In some embodiments, as Figure 1 shown, the first sensor module 11 includes: a first sensor 111 and a control chip 112. The first sensor 111 is configured to detect whether a user leaves a preset area, and output an induction signal when it detects that a user leaves the preset area. The control chip 112 is configured to output a first detection signal in response to the induction signal, and the first detection signal is a signal that switches between a high level and a low level.

[0120] In some embodiments, the first sensor 111 can be a pyroelectric infrared sensor (PIR). The pyroelectric infrared sensor can detect infrared rays emitted by humans or certain animals and convert them into electrical signals for output. When some crystals are heated, equal amounts of opposite-sign charges will be generated at both ends of the crystal. This phenomenon of polarization due to thermal changes is called the pyroelectric effect. Usually, the bound charges generated by the spontaneous polarization of the crystal are neutralized by the free electrons attached to the crystal surface from the air, and its spontaneous polarization electric moment cannot be manifested. When the temperature changes, the centers of positive and negative charges in the crystal structure shift relative to each other, the spontaneous polarization changes, and charge depletion will occur on the crystal surface. The condition of charge depletion is proportional to the degree of polarization. Figure 4 shows the principle of the formation of the pyroelectric effect.

[0121] The pyroelectric sensor utilizes the pyroelectric effect and is a temperature-sensitive sensor. It consists of ceramic oxides or piezoelectric crystal elements, with electrodes formed on both surfaces of the elements. When the temperature within the monitoring range of the sensor changes by ΔT, the pyroelectric effect generates a charge ΔQ on the two electrodes, that is, a weak voltage ΔV is generated between the two electrodes. Due to its extremely high output impedance, there is a field-effect transistor in the sensor for impedance transformation. The charge ΔQ generated by the pyroelectric effect will combine with the ions in the air and disappear. When the ambient temperature remains stable, ΔT = 0, and the sensor has no output. When a human body enters the detection area, since there is a difference between the human body temperature and the ambient temperature, ΔT is generated, and a signal is output; if the human body remains stationary after entering the detection area, the temperature does not change, and the sensor also has no output. Therefore, this type of sensor can detect the activities of humans or animals. The first sensor 111 mainly consists of a housing, a filter, a pyroelectric element (sensing sensitive element), a field-effect transistor FET, etc. Among them, the filter is arranged at the window to form a window for infrared rays to pass through. The filter can effectively filter out the short wavelengths (about 5um or less) of sunlight and fluorescent light. The pyroelectric element (sensing sensitive element) converts the weak change of the infrared signal with a wavelength between 8 - 12um into an electrical signal. In order to be sensitive only to the infrared radiation of the human body, a special Fresnel lens is usually covered on its radiation surface, significantly suppressing environmental interference.

[0122] In some embodiments, the first sensor module 11 further includes: a Fresnel lens 14, which is arranged on the incident light side of the pyroelectric infrared sensor and is used to converge the received infrared light to the receiving end of the pyroelectric infrared sensor. Figure 5 The schematic diagram of the detection by the first sensor module provided in some embodiments of the present disclosure is as Figure 5 shown. The Fresnel lens 14 is made according to the Fresnel principle, divides the infrared light into a visible area and a blind area, and at the same time has a focusing effect, greatly increasing the sensitivity of the pyroelectric passive infrared sensor (PIR). The Fresnel lens has two forms: refractive and reflective. Its first function is the focusing effect, refracting (reflecting) the pyroelectric infrared signal onto the pyroelectric infrared sensor; the second function is to divide the detection area into several bright areas and dark areas, enabling the moving objects entering the detection area to generate a changing pyroelectric infrared signal on the pyroelectric infrared sensor in the form of temperature change, so that the pyroelectric infrared sensor can generate a changing electrical signal. In the static state, infrared light exists in space. Due to the complementary technology adopted by the dual-element probe, no electrical signal output will be generated. In the dynamic state, when a human body passes by the probe and is successively sensed by source A or source B, the dual-source loses the complementary balance effect and very sensitively generates a signal output.

[0123] Among them, for the control of the sensing range and distance of the first sensor 111, it can be achieved through lens selection, thereby achieving a more precise sensing effect.

As Figure 6 shown, the display device 10 further includes an outer frame 30, and the outer frame 30 surrounds the display module 13. The first sensor 111 can be disposed on one side of the display module 13, and a detection window corresponding to the first sensor 111 is provided on the outer frame 30.

[0125] Figure 7 The following is a schematic connection diagram of the first sensor and the control chip provided in some embodiments of the present disclosure. As Figure 7 shown, the first sensor 111 has a first pin 1, a second pin 2, and a third pin 3. The first pin 1 of the first sensor 111 is connected to the power supply terminal VCC, the second pin 2 of the first sensor 111 serves as the output terminal; the third pin 3 of the first sensor 111 is grounded; the control chip 112 has first pins 1 to eighth pins 8. The first pin 1 of the control chip 112 is connected to the first power supply terminal VDD, the second pin 2 of the control chip 112 is connected to the second pin 2 of the first sensor 111, the third pin 3 of the control chip 112 is connected to the first pin 1 of the first sensor 111, the fourth pin 4 of the control chip 112 is connected to one end of the first resistor R1, and the other end of the first resistor R1 is connected to the pulse input terminal PULSE; the fifth pin 5 of the control chip 112 is connected to the output terminal VOUT; the eighth pin 8 of the control chip 112 is grounded; the seventh pin 7 is connected to the first end of the second resistor R2, the second end of the second resistor R2 is connected to the first end of the third resistor R3, and the second end of the third resistor R3 is grounded; the sixth pin 6 is connected to the connection node between the second resistor R2 and the third resistor R3. A capacitor C1 is connected between the first power supply terminal VDD and the ground terminal GND. Among them, the pulse signal on the pulse input terminal PULSE is used to adjust the sensitivity of the output signal of the control chip 112.

[0126] In some embodiments, the controller 12 is further configured to shape the waveform of the received signal. Among them, when determining the duration of the valid edge, the duration of the valid edge in the shaped waveform is determined. It should be noted that shaping the waveform of the received signal means removing the noise in the signal, that is, removing the spikes in the signal waveform, and the duration of the valid edge in the signal waveform remains unchanged or basically unchanged before and after shaping. By shaping the signal waveform, the noise interference in the signal can be removed. Figure 8 The following is a schematic diagram of the control chip provided in some embodiments of the present disclosure. As Figure 8As shown in the figure, the control chip 112 includes: a shaping unit 122, a switching transistor 123, and a logic judgment unit 121. Among them, the shaping unit 122 is connected between the data interface and the logic judgment unit 121, and the data interface is also connected to the fourth resistor R4. The shaping unit 122 is used to shape the waveform of the signal received by the data interface. The control electrode of the switching transistor 123 is connected to the logic judgment unit 121, the first electrode is connected to the shaping unit 122, and the second electrode is grounded. The logic judgment unit 121 is used to determine the duration of the valid edge of the signal waveform.

[0127] Figure 9 It is a schematic diagram of the modules of the display device provided in some other embodiments of the present disclosure. As Figure 9 shown, in some other embodiments, the sensor module in the display device 10 further includes: a second sensor module 15, and the second sensor module 15 is configured to detect the actual brightness of the external environment and generate a corresponding second detection signal. The controller 12 is specifically configured to, when it is determined that the duration of the valid edge of the received signal is within the signal identification range corresponding to the second detection signal, output an adjustment instruction to the display module 13 according to the received signal to adjust the display parameters of the display module 13, so that the display parameters of the display module 13 can change according to the actual brightness of the environment, thereby improving the user's viewing experience.

[0128] In one example, the controller 12 is specifically configured to, when it is determined that the duration of the valid edge of the received signal is within the signal identification range corresponding to the second detection signal, determine the actual brightness level corresponding to the actual brightness according to the amplitude of the received signal and the signal amplitudes corresponding to multiple brightness levels; and output an adjustment instruction to the display module 13 according to the actual brightness level to adjust the display parameters of the display module 13.

[0129] Among them, the display parameters of the display module 13 may include parameters such as brightness and color temperature. For example, multiple brightness levels include: high brightness, medium brightness, and low brightness. The signal amplitude range corresponding to high brightness is V1 to V2, the signal amplitude range corresponding to medium brightness is V3 to V4, and the signal amplitude range corresponding to low brightness is V5 to V6. When the controller 12 determines that the amplitude of the signal it receives is within the range of V1 to V2, it determines that the current actual brightness is high brightness, and outputs an adjustment instruction to the display module 13 to adjust the brightness of the display module 13 to between L1 and L2; when the controller 12 determines that the amplitude of the signal it receives is within the range of V3 to V4, it determines that the current actual brightness is medium brightness, and outputs an adjustment instruction to the display module 13 to adjust the brightness of the display module 13 to between L3 and L4; when the controller 12 determines that the amplitude of the signal it receives is within the range of V5 to V6, it determines that the current actual brightness is high brightness, and outputs an adjustment instruction to the display module 13 to adjust the brightness of the display module 13 to between L5 and L6. In one example, the higher the brightness level of the actual brightness of the external environment (i.e., the brighter the brightness), the higher the adjusted display brightness of the display module 13.

[0130] Among them, when the display device 10 includes the second sensor module 15, the controller 12 may also first shape the signal output by the second sensor module 15, and then detect the amplitude of the signal.

[0131] It should be noted that the embodiments of the present disclosure are described by taking the display device 10 including the first sensor module 11 or the second sensor module 15 as an example. In other examples, the display device 10 may include both the above-mentioned first sensor module 11 and second sensor module 15, and of course, other sensor modules may also be included.
