[0055] With the development of the technology of the automotive cabin, the demand for personalization of the vehicle interior personnel is increasing, such as providing independent and personalized sound information, picture information, temperature information for drivers and passengers in different positions. The existing automotive cabin provides personalized pictures for different passengers by setting multiple screens.

[0056] Since the sound is spread in all directions, the independent sound effect provided by the headrest sound and sound shield function is poor. The existing display unit capable of realizing directional sound emission is placed separately with the display component and the directional sound emission unit, and cannot realize both display and directional sound emission functions, cannot realize separate display of different sound emission areas, and has limited functions in the vehicle cabin.

[0057] Embodiment one:

[0058] As shown in Figure 1 , Figure 2 , the embodiment one of the present application provides a display 100, comprising: a display component 110 for displaying images; a directional sound emission component 120 connected to the display component 110, the directional sound emission component 120 is used for emitting sound to a preset direction.

[0059] Through the directional sound emission component 120 connected to the display component 110, the directional sound emission component 120 is used for emitting sound to a preset direction, the preset direction is a specific position in the area where the display 100 is located, which realizes that the sound information obtained by personnel at different positions in the area where the display 100 is located does not affect each other, and improves the use experience of the display screen. The existing multiple screens are integrated into one screen, which saves the internal space of the vehicle and saves the use cost.

[0060] The preset direction is a specific position in the space where the display 100 is located, and the space where the display 100 is located refers to the space within a preset distance from the display 100. For example, the preset distance is 0m-100m, and the space where the display 100 is located refers to the space within 100m from the display 100; the preset distance is 50m-100m, and the space where the display 100 is located refers to the space within 50m-100m from the display 100. Correspondingly, the preset direction is a certain direction within 100m from the display 100, such as the ten o'clock direction, the six o'clock direction, etc., at this time the preset direction is a diffusion triangle or diffusion cone with the display 100 as the diffusion point; or the preset direction is a certain direction within 50m-100m from the display 100, such as the ten o'clock direction, the six o'clock direction, etc., at this time the preset direction is a sector with the display 100 as the center.

[0061] The display component 110 is a component that receives a specific display signal and displays the signal in the form of an image. The display component 110 is a structure for displaying images. The display component 110 includes but is not limited to a cathode ray tube display, a liquid crystal display, an LED display.

[0062] Further, the directional sound emission component 120 is adapted to realize directional sound emission by audible sound waves and / or ultrasonic waves.

[0063] The frequency of audible sound waves is between 20 Hz and 20 kHz, which is the range of sound that humans can perceive. The sound of speech, music, and the like in daily life belong to audible sound waves. The directional sound of audible sound waves is usually realized through beamforming technology. Beamforming technology often controls the phase and amplitude of audible sound waves through multiple loudspeaker units, which can be presented in the form of an array. By precisely adjusting the sound emission time and intensity of each loudspeaker unit, one or more sound beams are formed, thereby enhancing sound propagation in a specific direction while canceling each other out in other directions to reduce sound propagation and diffusion. The implementation of beamforming technology is to control the output of the loudspeaker array through digital signal processing (DSP) technology, so that sound can be superimposed in a specific direction to enhance the directional propagation of sound in the specified direction while canceling each other out in other directions to reduce sound propagation and diffusion. Beamforming technology is suitable for long-distance sound directional propagation and is usually used for fixed installation.

[0064] The frequency of ultrasonic waves is above 20 kHz, which is beyond the upper limit of human hearing. Ultrasonic waves have high reflectivity and are often used for non-destructive testing and positioning. By using ultrasonic waves as a carrier, audio information is carried by modulating the ultrasonic wave signal, and the ultrasonic wave is demodulated into audible sound using the nonlinear effect in the air.

[0065] Further, the directional sound component 120 includes an ultrasonic sound layer 121 for ultrasonic sound emission to at least one preset direction.

[0066] The implementation of ultrasonic directional sound is usually to use an ultrasonic transmitter to generate high-frequency ultrasonic waves, and to superimpose audio information on the ultrasonic waves through modulation technology. When the ultrasonic wave reaches a specific area, the nonlinear effect of the air produces audible audio. The ultrasonic transmitter is usually suitable for short-distance and specific small-range sound directional propagation, and has a relatively compact structure, relatively simple device design, and is easy to install and use.

[0067] Sound waves are mechanical disturbances caused by the alternating expansion and compression of the medium. As a result of the disturbance, the density, pressure, and temperature of the medium change. If the disturbance is very small, the acoustics are small quantities, and the acoustics are linearly related. The equation governing the motion of sound waves is also linear. The acoustic theory constructed from this is linear acoustics. However, if the change in these acoustic quantities is not small, but limited, or even quite large, the relationship between the acoustic quantities is no longer linear, and the equation governing the motion of sound waves is also no longer linear. The acoustic theory constructed from this is nonlinear acoustics. At this time, the propagation speed of the sound disturbance is related to the strength of the disturbance, and a series of nonlinear phenomena such as wave form distortion, sound saturation, and nonlinear interaction between sound waves occur during the propagation of sound waves.

[0068] The ultrasonic sound emitting layer 121 is configured to emit ultrasonic waves in at least one preset direction, such as one preset direction, two preset directions, and three preset directions as shown in the figure. Figure 3

[0069] The ultrasonic sound emitting layer 121 generates directional sound by using ultrasonic modulation and self-demodulation technology. First, the audio signal is modulated onto a high-frequency ultrasonic carrier wave. Due to the high frequency, the ultrasonic wave has good directivity and can accurately control the direction of sound propagation. When the modulated ultrasonic wave propagates in the air and encounters an obstacle, the nonlinear effect of the air causes part of the ultrasonic energy to be demodulated back to the original audio signal, which is then received by the human ear.

[0070] Further, the ultrasonic sound emitting layer 121 includes at least one sound emitting unit 1211 configured to emit ultrasonic waves in a preset direction.

[0071] The sound emitting unit 1211 is the smallest unit for emitting sound in a preset direction. When the ultrasonic sound emitting layer 121 includes only two sound emitting units 1211, the ultrasonic sound emitting layer 121 can realize directional sound emission in two different preset directions or in the same preset direction.

[0072] The sound emitting unit 1211 is connected to the display component 110 and is arranged on one side of the display component 110 in the thickness direction to obtain a display screen that both displays and emits directional sound.

[0073] Further, the sound emitting unit 1211 includes a vibration cavity 1212 and an ultrasonic sound emitter 1213 arranged in the vibration cavity 1212.

[0074] Each sound emitting unit 1211 includes a vibration cavity 1212 and an ultrasonic sound emitter 1213 arranged in the vibration cavity 1212. Arranging the ultrasonic sound emitter 1213 in the vibration cavity 1212 can reserve sufficient space for the vibration of the ultrasonic sound emitter 1213 and also reserve air to facilitate the propagation of sound waves. In addition, it has a certain sealing effect, which ensures the normal operation of the ultrasonic sound emitter 1213 and improves the service life of the ultrasonic sound emitter 1213.

[0075] Further, the sound emitting side of the ultrasonic sound emitter 1213 and the light emitting side of the display component 110 are oriented in the same direction.

[0076] Orienting the sound emitting side of the ultrasonic sound emitter 1213 and the light emitting side of the display component 110 in the same direction makes the visual area of the display component 110 and the audible response range of the ultrasonic sound emitter 1213 approximately coincide, which conforms to the visual and auditory habits of users.

[0077] ​Further, the display 100 further comprises an insulation layer 130, which is arranged between the display component 110 and the directional sound component 120 along the thickness direction of the display 100.

[0078] As shown in Figure 2 , the thickness direction of the display 100 is the Z direction, as shown in Figure 2 , Figure 4 , the length direction and the width direction of the display plane of the display 100 are the Y direction and the X direction respectively.

[0079] The insulation layer 130 realizes the insulation and shielding between the display component 110 and the directional sound component 120, ensures the stability of the dielectric space of the display component 110, and provides a buffer space for the vibration of the ultrasonic sound layer 121.

[0080] The material of the insulation layer 130 is not specifically limited, and generally uses indium tin oxide / polyethylene terephthalate composite material, polypropylene, polycarbonate and the like. The thickness of the insulation layer 130 is not specifically limited, such as 0.002mm-12mm.

[0081] Further, the display component 110 comprises a refractive layer 111, which is used for refracting the light emitted by the light source.

[0082] The refractive layer 111 changes the direction of the light emitted by the light source by refracting the light, and obtains the display effect of directional light.

[0083] As shown in Figure 5 , the refractive layer 111 uses the refraction of liquid crystal to light to generate pictures in different directions. The principle is that: the liquid crystal has an electro-optic effect, the molecules in the liquid crystal layer can present a specific arrangement under the action of a specific electric field, so that the light of the light source can be deflected according to the preset direction. When the electric field is applied to the liquid crystal layer, the liquid crystal molecules will rearrange and change their influence on the light. By controlling the light direction of the display component 110 or blocking the light of the light source through the electro-optic effect of the liquid crystal, different refractive index columns such as column A and column B are formed on the display 100, and then different direction picture information is formed.

[0084] As shown in Figure 4 , the display components 110 corresponding to different direction picture information can be arranged in cross direction along the column direction. In addition, the display components 110 corresponding to different direction picture information can also be arranged in cross direction along the row direction; or can be arranged in cross direction along the row direction and the column direction. The essence of cross arrangement is the control of the refractive index of the refractive layer 111 in different directions. When it is detected that different picture information A and B of the display 100 need to be watched at the same time at the left side of the display 100 and the right side of the display 100, the pixel points of the color display layer display the contents of picture A and picture B in interval. As shown in Figure 4As shown, the pixel points of the picture A and the pixel points of the picture B are displayed at intervals, such as Figure 5 As shown, the picture A and the picture B are respectively projected to different areas through the change of the arrangement mode of the refractive layer 111.

[0085] Liquid crystals can be divided into thermotropic liquid crystals and lyotropic liquid crystals. Thermotropic liquid crystals refer to liquid crystals formed by a single compound or a uniform mixture of a small number of compounds. Generally, the substances only show liquid crystal phase in a certain temperature range. The molecular weight of the typical long rod-shaped thermotropic liquid crystal is generally about 200-500 g / mol. Lyotropic liquid crystals are liquid crystals formed by two or more compounds including solvent compounds. They appear in a certain range of solute molecular concentration in a solution. The solvent is mainly water or other polar molecular solvents. The main reason for causing long-range order of molecular arrangement in this liquid crystal is the interaction between solute and solvent molecules, and the interaction between solute molecules is secondary. Lyotropic liquid crystals are liquid crystals formed by two or more compounds including solvent compounds.

[0086] The display 100 transmits the respective independent sound and picture information to a specific position in the area where the display 100 is located through the refractive layer 111 and the directional sound emitting component 120.

[0087] Further, the display component 110 further comprises a display layer 112, which is arranged on the first side of the refractive layer 111, the first side of the refractive layer 111 being the side away from the directional sound emitting component 120, and the display layer 112 is used to generate a light source.

[0088] The display layer 112 generates a light source, and the light rays of the light source change the propagation direction of the light rays of the display layer 112 at different positions through the refractive layer 111, so as to realize the effect of directional light emission and directional display.

[0089] Further, the display layer 112 comprises at least two pixel areas, which are configured to be individually controlled.

[0090] The display layer 112 comprises a plurality of pixel areas, which are arranged at intervals in the display plane and are respectively used to display different pixel points, so as to realize display in different directions.

[0091] As shown in Figure 7 , Figure 8 As shown, one person uses the display 100 on the left side of the display 100 and one person uses the display 100 on the right side of the display 100 at the same time, the display 100 simultaneously displays the picture A and the picture B, and then the light rays are displayed in zones through the refractive layer 111, the left person can only see the picture A and control the picture A, and the right person can only see the picture B and control the picture B, without affecting each other.

[0092] Furthermore, at least two pixel intervals are set.

[0093] At least two pixel regions are spaced apart along one or more directions. The pixel regions are spaced apart along the Y and / or X directions of the display plane. With the size of the display 100 remaining constant, the more pixel regions there are, the higher the resolution of the display 100.

[0094] Furthermore, the display component 110 also includes a touch layer 113, which is disposed on the second side of the refractive layer 111. The second side of the refractive layer 111 is the side of the refractive layer 111 that is close to the directional sound-emitting component 120. The touch layer 113 is used to identify control signals.

[0095] The touch layer 113 is disposed on the side of the refractive layer 111 near the directional sound-emitting component 120. The touch layer 113 enables people in different sound-emitting areas and positions to display and touch the display 100 independently, and the obtained sound and image information does not affect each other.

[0096] like Figure 7 , Figure 8 As shown, one person uses the monitor 100 simultaneously on the left and right sides of the monitor 100. The monitor 100 displays screen A and screen B at the same time. The light is then divided into zones by the refractive layer 111. The person on the left can only see screen A and touch screen A, while the person on the right can only see screen B and touch screen B. The two do not affect each other.

[0097] The touch layer 113 is typically made of a transparent conductive material, such as indium tin oxide (ITO). The basic principle of the touch layer 113 is based on the electrical properties of the human body. When a finger touches or approaches the surface of the display 100, the finger forms a coupling capacitor with the capacitive touch layer on the display 100. A small current is applied to the four corners or edges of the display 100. By detecting changes in this current, the controller of the display 100 can calculate the specific location of the touch point. By recognizing the capacitance changes caused by a finger touching the display 100, touch information is collected and transmitted to the control module 300.

[0098] Furthermore, in the thickness direction of the display 100, the directional sound-emitting component 120 is disposed on the light-emitting side of the display component 110.

[0099] The directional sound-emitting component 120 is disposed on the light-emitting side of the display component 110, which avoids the influence of the display component 110 on the vibration and sound generation of the directional sound-emitting component 120, improves the propagation quality of directional sound, ensures the overall display and sound quality of the display 100, and improves the service life of the display 100.

[0100] Furthermore, the display 100 also includes at least one substrate 140, which is disposed on the light-emitting side of the display component 110 and / or the sound-emitting side of the directional sound-emitting component 120 along the thickness direction of the display 100.

[0101] The substrate 140 is disposed on the light-emitting side of the display component 110 and / or the sound-emitting side of the directional sound-emitting component 120, which helps to improve the physical strength of the display 100 on the light-emitting and / or sound-emitting sides. In the Z direction, the light-emitting side of the display component 110 is disposed opposite to the light-emitting side of the display component 110, the sound-emitting side of the directional sound-emitting component 120 is disposed opposite to the sound-emitting side of the directional sound-emitting component 120, and the light-emitting side of the display component 110 is disposed opposite to the sound-emitting side of the directional sound-emitting component 120.

[0102] like Figure 1 As shown, substrates 141 and 142 are provided on both sides of the display 100 along the Z direction to provide physical and chemical protection for the functional layers inside the display 100.

[0103] Example 2:

[0104] like Figure 8 As shown, Embodiment 2 of this application provides a display system, including an identification module 200 and the display 100. The identification module 200 is connected to the display 100 and is used to identify the desired direction, which is a preset direction of the display 100.

[0105] The recognition module 200 identifies the required direction and then obtains the preset direction of the display 100, so that the sound information obtained by people in different positions within the area where the display 100 is located does not interfere with each other, thus improving the user experience of the display screen.

[0106] Furthermore, it also includes a control module 300, which is located between the recognition module 200 and the display 100.

[0107] The recognition module 200 identifies the desired direction, the control module 300 acquires the desired direction, obtains a preset direction based on the desired direction, and controls each component of the display 100 to emit light and sound in the preset direction, thereby obtaining a directional light and sound audiovisual effect.

[0108] Furthermore, the identification module 200 includes at least one of a pressure identification device, an image acquisition device, and a wireless location detection device.

[0109] The identification module 200 includes a pressure identification device 210, an image acquisition device 220, and a wireless location detection device 230.

[0110] The pressure recognition device 210 is not limited in type and can be a commonly used pressure sensor.

The display 100 integrates multiple screens into one screen, saves the internal space of the vehicle, and saves the use cost.

[0123] Further, based on the demand direction obtained by the recognition module 200, the display component 110 emits light to the demand direction, including: based on multiple demand directions obtained by the recognition module 200, the refraction layer 111 refracts light to the multiple demand directions.

[0124] When the demand direction obtained by the recognition module 200 is at least two, the display 100 is in a partition mode, the refraction layer 111 refracts light to the multiple demand directions, and the display 100 emits personalized screen information and sound information to the at least two demand directions, and personnel in the at least two demand directions adjust the sound and the image individually by touching the display 100.

[0125] Further, the recognition module 200 includes at least one of a pressure recognition device, an image acquisition device, and a wireless position detection device, and based on multiple demand directions obtained by the recognition module 200, including:

[0126] The pressure recognition device detects pressure information of a to-be-detected area, and obtains a demand direction in response to the pressure information satisfying preset pressure information.

[0127] And / or, the image acquisition device detects image information of a to-be-detected area, and obtains a demand direction in response to the image information satisfying preset image information.

[0128] And / or, the wireless position detection device detects target object information in a to-be-detected area, and obtains a demand direction in response to the target object information satisfying preset target object information.

[0129] The pressure recognition device 210 is used to monitor the pressure information of personnel in the area where the display 100 is located. When the pressure signal of the pressure sensor reaches the set threshold value, it is determined that there is personnel at this position. The direction of this position is the demand direction of the recognition module 100, and the preset direction of the display 100 in the display system.

[0131] The wireless position detection device 230 is used to monitor the motion information of the person in the area where the display 100 is located. For example, the millimeter wave radar calculates the distance between the person and the display 100, and provides distance information for the directional sound emitting component 120 in the display 100, and then sends the sound to the person in a specific distance range.

[0132] The control module 300 receives the number of persons using the display 100 and the position area from the identification module 200, and divides the image and sound of the display 100 into multiple independent partitions according to the distribution of the persons watching the display 100, converts the image and sound data into partition signals, and outputs the partition signals to the directional sound emitting component 120 of the display 100. On the other hand, the control module 300 receives the touch signal returned by the touch layer 113 in the display 100, and identifies the person touching the display 100 in combination with the image information, and adjusts the partition of the picture and the sound.
