Description

Technical Field

[0001] Embodiments of the present utility model relate to the technical field of display devices, and in particular, to a retractable light sensing structure and a display device. Background Art

[0002] In current display devices, in many scenarios, it is necessary to have both a remote control function and a function of adjusting the screen brightness at the same time. For the remote control function, an infrared sensor is generally set to receive the infrared remote control signal of the remote control, so as to realize the remote control function; for the function of adjusting the screen brightness, an ambient light sensor is generally set to receive the ambient light signal, and the screen brightness is adjusted according to the situation of the ambient light signal.

[0003] For the setting of the infrared sensor and the ambient light sensor, in existing display devices, these sensors are usually hidden inside a wide border, and then the interfering wavelength light is filtered through a lens so that the sensors can work normally. For example, a special lens that can filter non-infrared wavelengths is used in front of the infrared sensor to allow infrared light to pass through, so that the infrared sensor can work normally; then a transparent lens is used in front of the ambient light sensor to achieve dust prevention while allowing visible light to pass through, so that the ambient light sensor can work normally.

[0004] In addition, for the remote control requirement of current display devices, there is also a method of remote control behind the screen, that is, an infrared sensor is arranged by opening a hole on the back plate of the backlight module to achieve remote control. When using this method of remote control behind the screen, the infrared sensor is located behind the display screen of the display device, and the external signal needs to pass through the display screen before reaching the infrared sensor.

[0005] In the prior art, the setting methods of the infrared sensor and the ambient light sensor will cause the border of the display device to become wider, affecting the user's visual experience and increasing the cost. At the same time, it will also weaken the optical signal entering the sensor, affecting the user's control of the display device.

[0006] In view of this, how to overcome the defects existing in the prior art and solve at least one of the problems existing in the prior art is a difficult problem to be solved in this technical field. Summary of the Utility Model

[0007] In view of the above technical problems, an embodiment of the present utility model provides a telescopic light sensing structure and a display device. An infrared sensor and an ambient light sensor are integrated in a light sensing module, and then the telescopic movement of the light sensing module is realized through a motor. When this telescopic light sensing structure is applied to a pure display product, the entire telescopic light sensing structure is located behind the display device, without affecting the design of the narrow border. When the sensor needs to work, the light sensing module is driven by a linear motor to extend from the bottom of the display device, so that the infrared sensor and the ambient light sensor in the light sensing module can work normally. When the sensor does not need to work, the light sensing module is driven by the linear motor to retract into the bottom of the display device. In this way, the impact on the appearance of the product will be very small, and because the entire telescopic light sensing structure is arranged behind the display device, the width of the border will not be increased, and the design of the narrow border can be realized. When multiple products are spliced, the splicing seam of the picture display is smaller, the visual experience is better, the cost of using the border is reduced, and it meets the border requirements of pure display products.

The buckle structure connects and fixes the second connecting surface and the light sensing module in a vertical plane, and the limiting structure limits the second connecting surface and the light sensing module in a horizontal plane to fixedly connect the light sensing module to the second connecting surface.

[0017] In some embodiments, the buckle structure includes barbed buckles disposed on both sides of the light sensing module, and the light sensing module is connected to two side edges of the second connecting surface through the barbed buckles on both sides.

Through the setting of the ultrasonic sensor, the damage of the structure caused by the misoperation of the motor can be avoided. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The present utility model will be described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present utility model, but do not limit the present utility model in any form. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can be made. These all belong to the protection scope of the present utility model.

[0035] In order to make the purpose, technical solution and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0036] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in this specification of the present utility model are only for the purpose of describing specific embodiments and are not used to limit the present utility model. In addition, the technical features involved in the following various embodiments of the present utility model can be combined with each other as long as they do not conflict with each other.

[0037] In the prior art, display devices generally have infrared sensors and / or ambient light sensors. Among them, the display device can be a television, an intelligent interactive flat panel, a digital signage, etc. The infrared sensor is usually used to receive the infrared remote control signal emitted by the remote control to achieve the remote control function; the ambient light sensor is usually used to receive the ambient light signal to adjust the screen brightness according to the brightness of the ambient light. Usually, the infrared sensor and / or the ambient light sensor are arranged on a printed circuit board (Printed Circuit Board, abbreviated as: PCB) and are installed on the display device through the PCB.

[0038] For usage scenarios that require simultaneous setup of an infrared sensor and an ambient light sensor, existing display devices have the following problems: 1. The infrared sensor and the ambient light sensor are arranged inside the frame of the display device. At this time, the display device needs to have a relatively wide frame to accommodate the PCB. Currently, display devices are developing towards the trend of extremely narrow frames, especially for pure display products (such as digital signage), where the requirements for the frame width are more stringent. In scenarios where splicing is required for display, after splicing, the frame size will affect the visual appearance of the product. The narrower the frame, the smaller the splicing seam of the displayed image, and the better the visual appearance; the wider the frame, the larger the splicing seam of the displayed image, and the worse the visual appearance. Currently, if the infrared sensor and the ambient light sensor are arranged inside the frame of the display device, this traditional design can no longer meet the requirements for the frame width of pure display products and will increase the frame cost. 2. When arranging the infrared sensor in the way of behind-screen remote control, that is, the infrared sensor is arranged behind the display screen of the display device. In this case, the infrared remote control signal of the remote control needs to pass through the display screen to reach the infrared sensor. As a result, the quality of the infrared remote control signal will be affected, and the infrared remote control distance will be reduced, which will have a certain impact on the user experience. Moreover, this method cannot design an ambient light sensor because the ambient light will also be affected and weakened when passing through the display screen, which will cause the ambient light sensor to be unable to measure the true ambient light brightness. Therefore, based on the above two points, for usage scenarios that require simultaneous setup of an infrared sensor and an ambient light sensor, the traditional sensor setup method of display devices can no longer meet the requirements.

[0039] To solve the above problems, the embodiments of the present utility model provide a telescopic light sensing structure. By integrating the infrared sensor and the ambient light sensor into a light sensing module, and then realizing the telescoping of the light sensing module through a linear motor. When this telescopic light sensing structure is applied to a display device, the telescopic light sensing structure is located behind the bottom of the display device and does not affect the design of the narrow frame. When the sensor needs to work, the linear motor drives the light sensing module to extend from the bottom of the display device, so that the infrared sensor and the ambient light sensor in the light sensing module can work normally. When the sensor does not need to work, the linear motor drives the light sensing module to retract into the bottom of the display device. In this way, the impact on the product appearance will be very small, and because the entire telescopic light sensing structure is arranged behind the display device, it will not increase the width of the frame, and the design of a narrow frame can be achieved. When multiple products are spliced, the splicing seam of the displayed image is smaller, the visual appearance is better, and the frame usage cost is reduced, which meets the frame requirements of pure display products.

[0040] Specifically, with reference to the accompanying drawings, the embodiments of the present utility model will be further described below.

[0041] Reference Figure 1 and Figure 2As shown in the figure, an embodiment of the present utility model provides a telescopic light sensing structure, which includes a driving module 2, a light sensing module 3 and a connecting member 4 arranged behind the display device. An infrared sensor 3041 and an ambient light sensor 3042 are integrated inside the light sensing module 3. Among them, the driving end of the driving module 2 is connected to the connecting member 4, and the connecting member 4 is fixed to the light sensing module 3. The driving end of the driving module 2 drives the connecting member 4 to move, and drives the light sensing module 3 to move between a first position and a second position. When the light sensing module 3 is in the first position, the light sensing module 3 is located within the projection range of the display device in the direction perpendicular to the display surface of the display device. When the light sensing module 3 is in the second position, the light sensing module 3 is located outside the projection range of the display device in the direction perpendicular to the display surface of the display device. When working, the driving end of the driving module 2 moves in a certain direction, which can drive the connecting member 4, and then drive the light sensing module 3 to move in this direction, so that the light sensing module 3 extends out of the display device or retracts into the display device. Generally speaking, it is preferably to set the moving direction of the light sensing module 3 as the vertical direction. When extending, it extends from the bottom of the display device, and when retracting, it retracts from the bottom of the display device. For the convenience of description, the subsequent movement of the light sensing module 3 will be described as moving in the vertical direction, and the supporting orientation will also be described as up and down.

[0042] Based on the above settings, in this embodiment, the infrared sensor 3041 and the ambient light sensor 3042 are integrated in a light sensing module 3, and then the telescopic function of the light sensing module 3 is realized through the driving module 2. When this telescopic light sensing structure is applied to a pure display product, the entire telescopic light sensing structure is located behind the bottom of the display device, without affecting the design of the narrow border around the front display device. When the sensor needs to work, the driving module 2 drives the light sensing module 3 to extend from the bottom of the display device, so that the infrared sensor 3041 and the ambient light sensor 3042 in the light sensing module 3 can work normally. When the sensor does not need to work, the driving module 2 drives the light sensing module 3 to retract into the bottom of the display device. In this way, the impact on the product appearance will be very small, and because the entire telescopic light sensing structure is arranged behind the display device, the width of the border will not be increased, and the design of the narrow border can be realized. When multiple products are spliced, the splicing seam of the picture display is smaller, the visual effect is better, and the border use cost is reduced, which meets the border requirements of pure display products.

[0043] Through the above settings, the driving module 2 can drive the connecting member 4 to move in the vertical direction, and then drive the light sensing module 3 to move in the vertical direction, realizing the telescopic function of the light sensing module 3. Figure 3 It is a schematic structural diagram when the telescopic light sensing structure extends. At this time, the light sensing module 3 is driven by the driving module 2 and the connecting member 4 to extend from below the rear cover 1, and then can receive the infrared remote control signal of the remote control and the ambient light signal around, and the signal does not need to pass through the screen, so there will be no discount in the effect. Refer toFigure 4 As shown, it is a schematic structural diagram of the retractable light-sensing structure when retracted. At this time, the light-sensing module 3 is driven by the driving module 2 and the connecting member 4 to retract from below the rear cover 1. In this state, the impact on the appearance of the product will be very small. And because the entire retractable light-sensing structure is arranged behind the display device, it will not increase the width of the frame, enabling a narrow-frame design. When multiple products are spliced, the splicing seam of the picture display is smaller, the visual effect is better, the cost of using the frame is reduced, and it meets the frame requirements of pure display products.

[0044] Refer to Figure 2 and Figure 5 As shown, in one embodiment, the rear cover 1 includes a back plate 101 and a bottom plate 102. The bottom plate 102 is perpendicularly arranged with the back plate 101. A through hole 103 matching the size of the light-sensing module 3 is provided on the bottom plate 102; the driving module 2 is fixed on the back plate 101, and its driving end faces the through hole 103, that is, is arranged downward, so as to drive the light-sensing module 3 to extend or retract along the through hole 103 through the connecting member 4. The schematic diagram when extending refers to Figure 3 As shown, and the schematic diagram when retracting refers to Figure 4 As shown. It should be noted that the driving module 2 can be fixed on the back plate 101 of the rear cover 1, or directly fixed at other positions behind the display device, as long as it does not affect the width of the frame around the display device and can drive the light-sensing module 3 to extend outside the display device for normal operation, and can retract the light-sensing module 3 into the display device without affecting the appearance and splicing.

[0045] Continue to refer to Figure 2 and Figure 5 As shown, in one embodiment, the driving module 2 includes a motor 201 and a motor fixing seat 202. The motor 201 is fixed in the middle of the motor fixing seat 202. Among them, the middle of the motor fixing seat 202 can be set as an arc-shaped groove matching the outer arc of the motor 201 to place the motor 201 on the arc-shaped groove for fixation, and the fixation can be by welding. The motor 201 can be a linear motor, and the driving end of the motor 201, that is, the driving shaft, faces the through hole 103 below to drive the connecting member 4 and the light-sensing module 3 to extend or retract along the through hole 103. In addition, connecting plates 203 are arranged on both sides of the motor fixing seat 202, and the motor fixing seat 202 is fixed to the back plate 101 through the connecting plates 203; among them, several through holes can be provided on the connecting plates 203, and corresponding connection holes can also be provided on the back plate 101 to fix the connecting plates 203 and the back plate 101 through connecting members such as bolts or screws.

[0046] Refer to Figure 2 and Figure 6As shown, in one embodiment, the connecting member 4 includes a first connecting surface 401, a second connecting surface 402, and a supporting surface 403. The first connecting surface 401 and the second connecting surface 402 are arranged in parallel, and the supporting surface 403 is connected to one side of the first connecting surface 401 and the second connecting surface 402. Among them, the first connecting surface 401, the second connecting surface 402, and the supporting surface 403 can be an integrated structure. The first connecting surface 401, the second connecting surface 402, and the supporting surface 403 together form a U-shaped connecting support for connecting the driving module 2 and the light sensing module 3.

[0047] Continue to refer to Figure 2 and Figure 6 As shown, in one embodiment, the driving end of the driving module 2 is connected to the first connecting surface 401, that is, the driving shaft of the motor 201 is connected to the first connecting surface 401. It should be noted that the motor 201 can be a linear motor, and the driving shaft of the motor 201 is perpendicularly connected to the first connecting surface 401, and thus can drive the first connecting surface 401 to move up and down in the vertical direction. The light sensing module 3 is fixedly connected to the second connecting surface 402; the light sensing module 3 and the second connecting surface 402 can be connected and fixed by means of a buckle.

[0048] Continue to refer to Figure 2 and Figure 6 As shown, in one embodiment, the light sensing module 3 is provided with a buckle structure 301 and a limiting structure 302 on the surface connected to the second connecting surface 402. The buckle structure 301 limits the second connecting surface 402 and the light sensing module 3 in the vertical direction. That is to say, through the setting of the buckle structure 301, the light sensing module 3 is snap-fitted on the second connecting surface 402. When the second connecting surface 402 does not move, even if the light sensing module 3 is affected by gravity, it cannot fall downward and cannot move in the vertical direction relative to the second connecting surface 402; here, the vertical direction corresponds to Figure 6 in which it refers to the direction in which the output end of the motor 201 drives the light sensing module 3 to move. The limiting structure 302 limits the second connecting surface 402 and the light sensing module 3 in the horizontal direction to fixedly connect the light sensing module 3 to the second connecting surface 402; here, the horizontal direction corresponds to Figure 6 in which it refers to the direction of the plane of the second connecting surface 402. Figure 6 in which the horizontal direction can be divided into the front-back direction and the left-right direction. The limiting structure 302 limits the front-back direction; the left-right direction is limited by the buckle structure 301. Specifically, the buckle structure 301 includes inverted hook-shaped buckles provided on both sides of the light sensing module 3. The inverted hook-shaped buckle refers to a buckle extending upward from the upper end surface of the light sensing module 3, and the upper end of the buckle is in an inverted hook shape and hooks on the upper surface of the second connecting surface 402, so that the second connecting surface 402 and the light sensing module 3 cannot move relative to each other in the vertical direction and the left-right direction. Through both sides (for exampleFigure 6 Barbed buckles on the left and right sides in the middle connect the light sensing module 3 to two side edges of the second connection surface 402. The limiting structure 302 includes protruding limiting posts, and the positions of the other two sides (such as the front and back sides in the middle) of the light sensing module 3 are limited by the limiting posts. It should be noted that the limiting structure 302 is only shown and set on the front side of the light sensing module 3 in the figure. This is because during actual use, the light sensing module 3 only receives the up and down pulling and pushing forces in the vertical direction. Therefore, in the horizontal direction, it is actually not stressed. So the setting of the limiting structure 302 is a safety setting, and only one side needs to be set. Of course, both sides can also be set, that is, it can also be set on the back side blocked in the figure. The above descriptions of directions are all based on the attached drawings for the convenience of understanding, rather than limitations. Figure 6 As shown in FIGS.

[0049] Reference Figure 7 , Figure 8 And Figure 9 In one embodiment, the light sensing module 3 includes a lens assembly 303 and a sensor board 304. A placement groove 3031 is formed inside the lens assembly 303, and the sensor board 304 is arranged in the placement groove 3031. The sensor board 304 can be a PCB board. The opening of the placement groove 3031 faces upward. Referring to Figure 6 , the upward opening here refers to the direction towards the second connection surface 402 in Figure 6 . After the sensor board 304 is arranged inside the placement groove 3031, the overall height of the sensor board 304 and its components thereon needs to be less than the height of the upper surface of the placement groove 3031. The sensor board 304 can be fixed in the placement groove 3031 by bonding, screwing, etc. Two sensor board limiting posts 3033 can also be arranged in the placement groove 3031. Correspondingly, sensor board limiting grooves 3044 can be formed on both sides of the sensor board 304, and the sensor board 304 is limited and its position is determined by the sensor board limiting posts 3033 and the sensor board limiting grooves 3044.

[0050] In one embodiment, an infrared sensor 3041 and an ambient light sensor 3042 are arranged on the sensor board 304. A transparent lens is arranged on the lens assembly 303 at a position corresponding to the ambient light sensor 3042, and an infrared lens is arranged on the lens assembly 303 at a position corresponding to the infrared sensor 3041, so as to meet the working requirements of the infrared sensor 3041 and the ambient light sensor 3042. Specifically, during production, a special paint that can transmit infrared light can be sprayed on the surface of the lens assembly 303, and only the front of the ambient light sensor 3042 is covered and sprayed to meet the working requirements of the ambient light sensor.

[0051] In one embodiment, an ultrasonic sensor 3043 is provided on the sensor board 304, and the lens assembly 303 is provided with a bottom opening 3032 at a position corresponding to the ultrasonic sensor 3043. The receiving end of the ultrasonic sensor 3043 extends to the other side of the sensor board 304 and is located at the bottom opening 3032 of the lens assembly 303 to meet the working requirements of the ultrasonic sensor 3043. With the setting of the ultrasonic sensor 3043, when the user turns on the machine, the ultrasonic sensor 3043 detects whether there is an external object within the telescopic distance value of the motor 201 outside the light sensing module 3. For example, if the telescopic distance value of the motor 201 is 5 cm, then the ultrasonic sensor 3043 detects whether the distance between the light sensing module 3 and an external obstacle is within 5 cm; if so, it means that the distance between the external obstacle and the light sensing module 3 is too close, and at this time, the light sensing module 3 cannot be extended, so the motor 201 does not work at this time to avoid damaging the light sensing module 3 after extension; if not, it means that the distance between the external obstacle and the light sensing module 3 meets the requirements, so the motor 201 can be pushed outwards to reach the preset telescopic distance value of 5 cm, and then drive the connecting member 4 and then drive the light sensing module 3 to be pushed outwards. After being pushed out, the light sensing module 3 can work normally and receive signals. When the user turns off the machine, the motor 201 retracts the drive shaft in the reverse direction to retract the light sensing module 3 into the rear cover 1, and the light sensing module 3 is not visible from the outside.

[0052] In summary, the embodiment of the present utility model provides a telescopic light sensing structure, which integrates an infrared sensor and an ambient light sensor in a light sensing module, and then realizes the telescoping of the light sensing module through a motor. When this telescopic light sensing structure is applied to a pure display product, the entire telescopic light sensing structure is located behind the display device and does not affect the design of the narrow border. When the sensor needs to work, the light sensing module is extended from the bottom of the display device by a linear motor, so that the infrared sensor and the ambient light sensor in the light sensing module can work normally. When the sensor does not need to work, the light sensing module is retracted into the bottom of the display device by a linear motor. In this way, the impact on the appearance of the product will be very small, and because the entire telescopic light sensing structure is arranged behind the display device, the width of the border will not be increased, and the design of the narrow border can be realized. When multiple products are spliced, the splicing seam of the picture display is smaller, the visual effect is better, the cost of using the border is reduced, and it meets the border requirements of pure display products.

[0053] Furthermore, the distance of the external structure can also be identified by the ultrasonic sensor to determine the working state that the linear motor should be in. When the distance between the external obstacle and the light sensing module is too close, the motor does not work to avoid damaging the light sensing module after extension; when the distance between the external obstacle and the light sensing module meets the requirements, the motor works normally. With the setting of the ultrasonic sensor, the damage to the structure caused by the misoperation of the motor can be avoided.
