At this time, at least part of the light is reflected by the display panel to the second reflector. The second reflector reflects the incident light to the display panel and passes through the display panel and is received by the human eye.

[0039] Existing in-vehicle display devices are all flat displays, with poor effects. The far-image display device is a special optical device that extends an object originally at a short distance to a long distance through free-form surface technology, making it feel like telescoping when viewed by the eyes, and seeing a virtual image in the distance. The existing far-image display devices are relatively large in volume and are difficult to be applied to application scenarios where thin and light products are required.

[0040] For example, when we want to install a far-image display device inside a moving object such as a car or a recreational vehicle, or on a fixed object with limited installation space, the disadvantages of a large-volume far-image display device are very obvious. In the existing related technologies, the light emitted from the display screen is incident on the display panel, reflected by the display panel and then incident on the reflector, and after being reflected by the reflector, the light passes through the display panel and is received by the human eye. The applicant has found through research that since far-image display needs to be achieved, the propagation path of the light from the display screen to the reflector needs to be long enough, otherwise the effect of far-image display cannot be achieved. Therefore, in actual design, the distance between the display screen and the display panel is designed to be relatively far, or the distance between the display panel and the reflector is designed to be relatively far. The drawback of this is that a greater requirement is placed on the volume of the outer shell of the far-image display device, resulting in the volume of the far-image display device not being able to be reduced under the existing design.

[0041] Therefore, the present invention proposes a far-image display device.

[0042] Refer to Figure 1 and Figure 2, according to some embodiments of the present application, the present invention provides a far-image display device 100. The far-image display device 100 includes a housing 11, a display panel 13, an image generation unit 12, a first reflector 14, and a second reflector 15. The housing 11 forms a receiving cavity 111, and the housing 11 is provided with an opening communicating with the receiving cavity 111; the display panel 13 is disposed at the opening; the image generation unit 12 is disposed in the receiving cavity 111; the light emitted by the image generation unit 12 is reflected by the first reflector 14 and then incident on the display panel 13, reflected by the display panel 13 and then incident on the second reflector 15, and reflected by the second reflector 15 and then incident on the display panel 13 again and emitted from the display panel 13.

[0043] The display panel 13 has the property of being semi-transmissive and semi-reflective, and can reflect part of the light and transmit the other part of the light. Specifically, it can be a semi-transmissive and semi-reflective plate or provided with a semi-transmissive and semi-reflective layer 132. In the embodiments of the present application, it can also be that the display panel 13 includes a transparent glass substrate 131 and a semi-transmissive and semi-reflective layer 132 disposed on the side of the glass substrate 131 facing the receiving cavity 111. The image generation unit 12 can emit image information in the form of light. For example, the image generation unit 12 can be a display screen 121, specifically, it can be an ordinary display screen 121, an LCD display screen or an LED display screen. The display screen 121 can emit polarized light in a certain direction, polarized light in several directions, or light with all polarization directions. In terms of the arrangement in space position, the image generation unit 12 can be disposed between the display panel 13 and the first reflector 14. Both the first reflector 14 and the second reflector 15 are disposed in the receiving cavity 111 and on the same side of the image generation unit 12. The display panel 13 is disposed facing the first reflector 14 and the second reflector 15 respectively. The first reflector 14 can be a reflector, specifically, it can be a plane mirror, and the plane mirror is attached to the inner wall surface of the housing 11. In this way, the light emitted from the image generation unit 12 is incident on the first reflector 14, reflected by the first reflector 14 and then incident on the display panel 13. At this time, at least part of the light is reflected by the display panel 13 to the second reflector 15. The second reflector 15 reflects the incident light to the display panel 13 and passes through the display panel 13 and is received by the human eye. What the human eye sees is the virtual image on the reverse extension line of the light emitted from the display panel 13, realizing far-image display. In the related art, the light emitted by the image generation unit 12 is directly incident on the display panel 13, that is, the image generation unit 12 is located at Figure 1 the position where the first reflector 14 is located in the figure. In order to ensure that the path of the light incident on the second reflector 15 is long enough or the angle meets the requirements, the image generation unit 12 needs to be moved to the upper right corner, which increases the space of the receiving cavity 111, undoubtedly increases the thickness of the housing 11, and thus increases the volume of the far-image display device 100.

[0044] In the above-mentioned embodiment of the present invention, by setting the first reflector 14, the light emitted from the image generation unit 12 is reflected by the first reflector 14 and then incident on the display panel 13, thereby extending the length of the light incident on the second reflector 15, ensuring the telescopic image display effect. Compared with directly incidenting the light of the image generation unit 12 on the display panel 13, this embodiment sets the first reflector 14 and through reasonable spatial layout, the housing 11 of the telescopic image display device 100 can be designed to be thinner, thereby reducing the thickness of the telescopic image display device 100, and thus reducing the volume of the telescopic image display device 100. It should be noted that the thickness in the present invention refers to Figure 1 The thickness in the direction indicated by the arrow H in the figure. This embodiment is particularly suitable for scenes where the thickness of the telescopic image display device 100 is relatively high, such as in a car or a motorhome. The telescopic image display device 100 can be installed in the seat headrest of the car or motorhome, or on the inner wall surface of the motorhome. With the embodiment of the present application, the thickness of the device during telescopic image display is realized within 15 cm, and the virtual image distance can be realized between 1 m and 4 m.

[0045] Reference Figure 1 In some embodiments, the telescopic display device 100 further includes a sensing unit 16, a control element 17, and a compensation device 18. The sensing unit 16 is used to detect acceleration information and send it to the control element 17. The control element 17 generates a compensation instruction according to the received acceleration information, and sends the compensation instruction to the compensation device 18 to control the compensation device 18 to perform a compensation operation. The sensing unit 16 may be an inertial sensing unit, which may be installed on the housing 11 or other components of the telescopic display device 100. It is mainly used to measure the jitter information of the telescopic display device 100, and specifically, it may be the jitter or bump of the housing 11, because the jitter of the housing 11 may cause the jitter of the display panel 13. The control element 17 may be a controller, which is used to receive the jitter information measured by the sensing unit 16, and generate a compensation instruction according to the jitter information. Specifically, the jitter information includes acceleration information. Because this embodiment is to prevent the jitter of the telescopic display device 100, it is necessary to adjust or compensate when there is a jitter trend. If compensation is performed after the jitter is complete, it is meaningless, so generally displacement information is not measured. Specifically, the control unit 17 can generate a compensation instruction based on the received acceleration information, where the acceleration information may include the numerical value of the acceleration and the direction of the acceleration. The control unit 17 generates a corresponding compensation instruction based on the acceleration information to compensate for the possible jitter, thereby reducing the jitter or bump of the telescopic image display device 100. Especially when the telescopic image display device 100 is applied to a car or other moving object, jitter or bump is inevitable during the movement of the moving object. This embodiment has the function of protecting against bumps or jitters, preventing the virtual image from shaking significantly and affecting the viewing experience, thereby reducing the jitter of the telescopic image display device 100.

[0046] Referring to Figure 1 and Figure 3 Figure 3 , in some embodiments, the compensation device 18 includes a substrate 181, an air inflation pump 182, and an air inflation layer 183 communicating with the air inflation pump 182. A support platform 184 is provided on a side of the air inflation layer 183 facing away from the substrate 181, and the housing 11 is mounted on the support platform 184. The air inflation pump 182 inflates or sucks air from the air inflation layer 183 according to a received compensation instruction to perform a compensation operation. Specifically, the compensation device 18 may be a four-axis three-dimensional bump anti-shake air floating platform.

[0047] The air inflation pump 182 is connected to the control member 17 and is configured to receive the compensation instruction from the control member 17, and can function to inflate and suck air. The air inflation layer 183 may be an air cushion, which will expand when inflated and shrink when air is sucked. The substrate 181 may include a bottom plate and a connection end connected to each other. The connection end is used for connection with the outside. For example, if the telephoto display device 100 is mounted on a vehicle, the connection end is used for connection with the vehicle housing 11 to fixedly connect the telephoto display device 100. The air inflation pump 182 may be mounted at the bottom of the substrate 181, and the air inflation layer 183 is mounted on the top surface of the substrate 181. The substrate 181 can support the air inflation layer 183. The support platform 184 is used for mounting the housing 11, and the support platform 184 is provided on the air inflation layer 183. When the air inflation layer 183 inflates or deflates, the support platform 184 will move along with the change in the volume of the air inflation layer 183, causing the housing 11 to move together. Specifically, it may be a vertical movement, and the vertical direction is as shown by the arrow L in Figure 1 to play a role in compensating for jitter. Specifically, the air inflation pump 182 may be a four-corner air floating pump.

[0048] In some embodiments, both the number of the air inflation pumps 182 and the number of the air inflation layers 183 are multiple and are in one-to-one correspondence and communication. The support platform 184 is disposed in close contact with the air inflation layer 183. The one-to-one correspondence and communication between the air inflation pump 182 and the air inflation layer 183 means that each air inflation pump 182 is individually connected to an air inflation layer 183, and each air inflation pump 182 individually controls the amount of gas in each air inflation layer 183. In this way, by adjusting the volume of each air inflation layer 183, the movement of the support platform 184 can be adjusted. Specifically, the position of each part of the support platform 184 in the vertical direction can be controlled to play a role in preventing vertical jitter. In addition, since the air inflation layer 183 itself can play a buffering role and has a certain flexibility, it can also reduce jitter in all directions to a certain extent. The close contact between the support platform 184 and the air inflation layer 183 enables the support platform 184 to move along with the change in the volume of the air inflation layer 183, playing a role in anti-shake.

[0049] In some embodiments, the number of the inflatable pumps 182 and the inflatable layers 183 is four each, and the four inflatable layers 183 are distributed at the four vertex positions of the support platform 184. When the support platform 184 is square, the inflatable layers 183 can be distributed at the four vertices of the support platform 184, so that the tilt angle of the support platform 184 can be adjusted to the greatest extent. Of course, when the support platform 184 is circular, the inflatable layers 183 can be arranged on the outer periphery of the support platform 184, and the tilt angle of the support platform 184 can also be adjusted to the greatest extent, that is, the angle of the outer shell 11 is adjusted, so as to better play the role of anti-shake.

[0050] In some embodiments, the control member 17 includes a control circuit layer 19, the second reflector 15 includes a support area 151 and a reflection area 152, the reflection area 152 includes a concave mirror, and the concave mirror is arranged in the accommodation cavity 111 with the reflecting concave surface facing the display panel 13. The support area 151 is formed with a mounting hole, the reflection area 152 is arranged in the mounting hole, and the control circuit layer 19 is arranged on the side of the support area 151 facing away from the display panel 13.

[0051] The second reflector 15 can be a curved mirror, including a reflection area 152. The light emitted from the display screen 121 is reflected by the semi-transmissive and semi-reflective layer 132 onto the reflection area 152. Specifically, the reflection area 152 is a curved reflection area. The material of the reflection area 152 is glass, and a reflection coating is applied to the reflection area 152 for reflecting light. On the surface of the support area 151 away from the display screen 121, a control circuit layer 19 is provided. The control circuit layer 19 is arranged in a layered form on the side of the support area 151 away from the display panel 13, replacing the control member 17 in the related art; that is to say, setting the control circuit layer 19 in the support area 151 can cancel the setting of the control member 17, which can not only reduce the production cost, but also eliminate the need to assemble the control member 17, improve the assembly efficiency, and reduce the overall size of the telephoto display device 100, enabling the telephoto display device 100 to be installed in some small-sized spaces, such as the headrest area of a car. Moreover, the integrated design of the second reflector 15 and the control circuit layer 19 can reduce the vibration of the control circuit layer 19 during the driving of the car, so as to solve the problem of the loose installation of the control member 17 (PCB board) in the related art due to the separate setting. In addition, setting the control circuit layer 19 on the side of the support area 151 away from the display panel 13, that is to say, setting the control circuit layer 19 on the side of the support area 151 away from the image generation unit 12, the second reflector 15 can act as a heat insulation member to separate the control circuit layer 19 from the environment where the image generation unit 12 is located, so as to avoid the influence of the heat generated by the image generation unit 12 on the stability of the control circuit layer 19. It should be noted that when setting the control circuit layer 19 on the support area 151, the control circuit layer 19 needs to be avoided from the reflection area 152 to prevent the manufacturing of the driving circuit from damaging the thinner position of the curved reflection area.

[0052] In a specific embodiment, the manufacturing process of the control circuit layer 19 is similar to that of TFT (thin film transistor). For example, a conductive film can be deposited on the surface of the reflection area 152, a layer of photoresist is applied on the conductive film, and then a suitable mask is selected for exposure according to the pattern or shape of the control circuit layer 19 required. After the exposure is completed, etching can be carried out, which can be dry etching or wet etching. Finally, the remaining photoresist is removed by heating and curing to obtain the required control circuit layer 19; in addition, in a more specific embodiment, a protective film can be deposited on the reflection area 152, which can be physical vapor deposition or chemical vapor deposition.

[0053] In some embodiments, a touch layer 21 is provided on the side of the display panel 13 away from the accommodation cavity 111. The touch layer 21 can also be said to be a touch screen layer, or the display panel 13 is a touch screen, which can facilitate the user's operation and can be directly touched and controlled by hand.

[0054] In some embodiments, one side of the display panel 13 facing away from the accommodation cavity 111 has a light-emitting surface, and the included angle between the light-emitting surface and the central axis of the concave mirror ranges from 60° to 120°. Among them, the included angle between the light-emitting surface and the central axis of the concave mirror is as shown by Figure 1 α in. Limiting the included angle between the light-emitting surface and the central axis of the concave mirror to be between 60° and 120° enables the user to view the far-image display device 100 in a way of looking directly at the light-emitting surface, which conforms to the usage habit of the human eye A looking directly at the screen, can improve the user experience; at the same time, it can also reduce the dust falling on the light-emitting surface, reduce dust accumulation, and further reduce the wiping frequency, avoiding damage to the far-image display device 100. Further, the included angle between the light-emitting surface and the central axis of the concave mirror is 90°. During actual installation and use, the user can tilt the far-image display device 100 according to actual needs. For example, when the far-image display device 100 is installed at a high place, the far-image display device 100 can be tilted downward by a certain angle to ensure that the users below can look directly at the light-emitting surface when looking up at the far-image display device 100.

[0055] In one embodiment, a button 20 is provided on the housing 11. The button 20 is electrically connected to the control member 17, and the button 20 is used to implement human-computer interaction.

[0056] In some embodiments, the image generation unit 12 includes a display screen 121. A notch 112 is provided on the housing 11. A sliding frame 113 is slidably provided on the notch 112. The display screen 121 is detachably installed on the sliding frame 113. A charging interface 114 electrically connected to the display screen 121 is provided on the sliding frame 113. Here, the display screen 121 is one of LCD, OLED, and MLED, and can be pulled out of the housing 11 by pulling, and can be used alone as a display tablet, which is also convenient for the repair and replacement of the display screen 121. Specifically, a notch 112 is provided on the housing 11, a sliding frame 113 is slidably provided on the notch 112, the display screen 121 is installed on the sliding frame 113, the sliding frame 113 forms a card slot at least partially accommodating the display screen 121, and the sliding frame 113 can slide on the notch 112 to pull out the display screen 121 located on the sliding frame 113 together, facilitating the removal of the display screen 121. And, a charging interface 114 can be provided on the sliding frame 113 or the housing 11. When the display screen 121 is put back on the sliding frame 113, the display screen 121 can be charged by electrically connecting the charging interface 114 to the display screen 121. The charging interface 114 can be electrically connected to the display screen 121 through a power cord or directly docked in the form of a gold finger.

[0057] Refer to Figure 6 , Figure 6FIG. 1 is a flow chart of an anti-shake control method of a telescopic image display device 100 according to a first embodiment of the present invention. The present invention further provides an anti-shake control method of a telescopic image display device 100. The anti-shake control method of the telescopic image display device 100 can be applied to the above-mentioned telescopic image display device 100, and comprises the following steps:

[0058] S100, receiving acceleration information sent by the sensor unit 16;

[0059] Specifically, a sensor unit 16 may be provided on the housing 11 of the telescopic image display device 100. The sensor unit 16 may obtain the shaking information of the housing 11. The shaking information reflects the shaking of the telescopic image display device 100. The specific shaking information may be acceleration information. The acceleration information includes the magnitude and direction of acceleration. The sensor unit 16 sends the acceleration information to the control unit 17.

[0060] S200, generating a compensation instruction according to the acceleration information;

A support platform 184 is provided on the side of the air-filled layer 183 facing away from the substrate 181. The housing 11 is mounted on the support platform 184. The air pump 182 inflates or sucks air from the air-filled layer 183 according to the received compensation instruction to perform a compensation operation. The air pump 182 is connected to the control unit 17 and is used to receive the compensation instruction of the control unit 17. It can play the role of inflating and sucking air. The air-filled layer 183 can be an air cushion. When inflated, the air cushion will expand, and when sucked, the air cushion will shrink. The substrate 181 may include a bottom plate and a connection end that are connected to each other. The connection end is used to connect to the outside world. For example, if the telescopic display device 100 is installed on a car, the connection end is used to connect to the housing 11 of the car to fix the telescopic display device 100. The air pump 182 can be installed at the bottom of the substrate 181, and the air-filled layer 183 is installed on the bottom surface of the substrate 181. The substrate 181 can support the air-filled layer 183. The support platform 184 is used to install the housing 11, and the support platform 184 is arranged on the air-filled layer 183. When the air-filled layer 183 is inflated or deflated, the support platform 184 will move with the change of the volume of the air-filled layer 183, so that the housing 11 moves together, which plays a role in compensating for the shaking.

[0064] In the above embodiments of the present invention, the acceleration information of the housing 11 is obtained through the sensing unit 16, and the control member 17 receives the acceleration information and generates a compensation instruction, which is used to control the compensation device 18 to compensate for the jitter that the housing 11 will generate, thereby reducing the jitter of the telephoto display device 100.

[0065] According to some embodiments of the present application, the present invention also provides a vehicle, which is provided with a housing, an installation position is formed on the housing, and the telephoto display device 100 of any one of the above is installed on the installation position. The telephoto display device 100 can be applied to scenarios with relatively thin thickness requirements and scenarios where jitter often occurs, such as moving objects like cars or caravans. When a car or caravan is driving, jitter may often occur due to road conditions or the driver. The telephoto display device 100 of the present application can play an anti-jitter role. Moreover, the installation space of a car or caravan is limited, and there is a particular need for the relatively thin telephoto display device 100 of the present application. Specifically, the telephoto display device 100 can be installed on the headrest of a car seat or the inner wall surface of a caravan.

[0066] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
