[0001] This utility model relates to the field of display technology, and in particular to a multifunctional sensor adapter board and display. Background Technology

[0002] With the development of display technology, the demand for intelligent displays is increasing, and many sensor functions are beginning to be applied to displays.

[0003] Currently, placing LEDs and sensors too close together can cause mutual interference; for example, the light emitted by an LED can affect the operation of the brightness sensor. Therefore, traditional displays typically place LEDs and individual sensors as separate modules in different locations within the display, connecting them to the display's SOC via multiple cables. However, this separate design of LEDs and sensors in traditional displays results in each independent module occupying a large amount of space and complex wiring, making it unsuitable for use on small-sized displays. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

Therefore, the directional terms used are for explanation and understanding of this invention, and not for limiting it. Furthermore, in the accompanying drawings, structures that are similar or identical are indicated by the same reference numerals.

[0021] Reference Figure 1 and Figure 2This utility model provides a multifunctional sensor adapter board 100. The structure and working principle of the multifunctional sensor adapter board 100 are described in detail below with reference to the accompanying drawings. The multifunctional sensor adapter board 100 is applied to a display and includes: a board 10, with a recessed isolation notch 101 on its side for mounting with the display housing; the isolation notch 101 separates the board 10 into adjacent first plates 11 and second plates 12; an interface module 20 disposed on the board 10; an LED module 30 disposed on the first plate 11 and connected to the interface module 20; and a sensor module 40 disposed on the second plate 12 and connected to the interface module 20.

[0022] In practical implementation, the multi-functional sensor adapter board 100 is used on a display. This multi-functional sensor adapter board 100 is connected to the main control module of the display, which is typically a System on Chip (SOC). Through the connection of the multi-functional sensor 41 to the main control module of the display, the display can realize various functions of the sensor 41, such as automatically adjusting screen brightness according to ambient light, controlling the screen with an infrared joystick, and automatically turning the screen on and off. The multi-functional sensor adapter board 100 mainly includes a board 10, an interface module 20, an LED module 30, and a sensor module 40. The board 10 is a PCB (Printed Circuit Board). The side of the board 10 has a recessed isolation notch 101 for mounting with the display housing. The isolation notch 101 can be an elongated notch. The isolation notch 101 divides the board 10 into two adjacent parts: a first board 11 and a second board 12. The PCB printed circuits on the board 10 can be routed around the isolation notch 101, and normal routing is possible between the first board 11 and the second board 12. Interface module 20 is mounted on board 10, and can be mounted on either the first board 11 or the second board 12; no restriction is placed here. Interface module 20 is used to connect to the main control module of the display. Interface module 20 is specifically a socket structure with all signal ports for connecting to the adapter board. LED module 30 is mounted on the first board 11, while sensor module 40 is mounted on the second board 12. Both LED module 30 and sensor module 40 are connected to the corresponding ports of interface module 20. LED module 30 is mainly used to emit light to indicate the status of the display. Sensor module 40 can be composed of one or more sensors 41. The type of sensor 41 is not limited, including but not limited to infrared sensor 41, brightness sensor 402, distance sensor 41, etc.

[0023] In practical applications, the isolation notch 101 is used to mate with the display. During installation, the board 10 is mainly located inside the display housing, while the LED module 30 and sensor module 40 are mainly exposed outside the display housing. Specifically, during installation, a structure matching the shape of the isolation notch 101 is set inside the display housing to mate with the isolation notch 101. For example, an opaque baffle structure is set inside the display housing and inserted into the isolation notch 101. After installation, the first board 11 and the second board 12 are separated by an isolation notch 101. The LED module 30 and the sensor module 40 are located on opposite sides of the isolation notch 101 and are isolated by the display housing structure. When the LED module 30 is working, the light emitted by it can be blocked by the display housing structure and will not shine on the sensor module 40 on the second board 12, thus preventing interference with the sensor module 40 and making its operation more stable and reliable. Furthermore, since the LED module 30 and the sensor module 40 are integrated on a single board 10, compared to the traditional display method of placing the LED and each sensor 41 separately, the adapter board will not occupy too much space inside the display. At the same time, the LED module 30 and the sensor module 40 can be connected to the main control module of the display through the interface module 20 on the board 10, making the cable connection simpler.

[0024] In one embodiment, reference is made to Figure 1 The sensor module 40 includes multiple sensors 41, all of which are arranged at intervals on the second plate 12 and connected to the interface module 20. Specifically, the sensor module 40 consists of multiple sensors 41 of different types, including but not limited to an IR infrared sensor 401, a brightness sensor 402, and a TOF ranging sensor 403. All sensors 41 are connected to corresponding ports of the interface module 20 for power connection and signal transmission. These sensors 41 are primarily optical sensors; by selecting these sensors, the operating wavelength ranges of each sensor 41 are kept as separate as possible, reducing mutual interference between sensors 41. All sensors 41 are arranged at intervals along the same direction on the second plate 12, with a certain distance between adjacent sensors 41. When the adapter board is installed with the display, the orderly and spaced sensors 41 will not interfere with each other, resulting in more stable sensor operation.

[0025] Furthermore, referring to Figure 2One of the sensors 41 is an IR infrared sensor 401. The interface module 20 has GPIO ports, and the IR infrared sensor 401 is connected to the GPIO ports of the interface module 20. Specifically, one of the sensors 41 on the second board 12 is an IR infrared sensor 401, which is a device that can collect data by receiving infrared radiation emitted by an object. The interface module 20 has GPIO ports GPIO1 and GPIO2. The IR infrared sensor 401 is connected to the GPIO ports GPIO1 and GPIO2 of the interface module 20. Specifically, after the interface module 20 is wired to the display, the GPIO ports GPIO1 and GPIO2 of the interface module 20 are connected to the GPIO ports of the display's main control module (such as a SoC). Thus, the display's main control module communicates with the IR infrared sensor 401 through simple GPIO ports, realizing the function of the IR infrared sensor 401.

[0026] Furthermore, referring to Figure 2 The two sensors 41 are a brightness sensor 402 and a TOF distance measuring sensor 403. The interface module 20 has an IIC port, and both the brightness sensor 402 and the TOF distance measuring sensor 403 are connected to the IIC port of the interface module 20. In a specific implementation, the two sensors 41 on the second board 12 are a brightness sensor 402 and a TOF distance measuring sensor 403. The brightness sensor 402 is a sensor that automatically converts ambient light intensity into an electrical signal, and the TOF distance measuring sensor 403 is a distance measurement sensor based on the time-of-flight principle. The interface module 20 has IIC ports IIC_SCL and IIC_SDA. The brightness sensor 402 and the TOF distance sensor 403 are both connected to the IIC ports IIC_SCL and IIC_SDA of the interface module 20. Specifically, after the interface module 20 is connected to the display, the IIC ports IIC_SCL and IIC_SDA of the interface module 20 are connected to the IIC bus of the display's main control module (such as SoC). Thus, the display's main control module communicates with the IR infrared sensor 401 through IIC, realizing the functions of the brightness sensor 402 and the TOF distance sensor 403.

[0027] Furthermore, a silicone sleeve is fitted over the outside of the TOF ranging sensor 403. In practice, the operation of the TOF ranging sensor 403 is easily affected by the external environment. Therefore, fitting a silicone sleeve over the outside of the TOF ranging sensor 403 can reduce interference from external environmental factors.

[0028] In one embodiment, reference is made to Figure 2The system also includes a power supply module, which is located on the board 10 and connected to the interface module 20, the brightness sensor 402, and the TOF ranging sensor 403. The power supply module is used to supply power to the brightness sensor 402 and the TOF ranging sensor 403. In a specific implementation, the multi-functional sensor adapter board 100 further includes a power supply module, which is located on the board 10. It can be located on the first board 11 or the second board 12. The power supply module connects to the interface module 20, the brightness sensor 402, and the TOF ranging sensor 403. The power supply module draws power from the interface module 20 to independently power the brightness sensor 402 and the TOF ranging sensor 403, thereby ensuring their normal operation.

[0029] Furthermore, referring to Figure 2 The interface module 20 has a power port and a control port. Both the brightness sensor 402 and the TOF ranging sensor 403 have power supply ports. The power supply module includes a first transistor Q1 and a first PMOS transistor Q2. The base of the first transistor Q1 is connected to the control port of the interface module 20, and its collector is connected to the power port and the gate of the first PMOS transistor Q2. The source of the first PMOS transistor Q2 is connected to the power port of the interface module 20, and its drain is connected to the power supply ports of the brightness sensor 402 and the TOF ranging sensor 403. Specifically, the interface module 20 has a +3.3V power port and a control port VCC_CTL. Specifically, after the interface module 20 is connected to the display, the +3.3V power port of the interface module 20 is connected to a power source to obtain 3.3V DC power. The control port VCC_CTL is connected to the I / O port of the display's main control module to transmit the power control signals of the main control module. The power supply module may include a first transistor Q1, a first PMOS transistor Q2, a first resistor R5, a second resistor R6, a third resistor R7, a first capacitor C1, and a second capacitor C2. The first transistor Q1 may be an NPN transistor. The base of the first transistor Q1 is connected to the control port VCC_CTL of the interface module 20 through the first resistor R5. The collector of the first transistor Q1 is connected to the power supply port +3.3V through the second resistor R6 and the third resistor R7 in series. The gate of the PMOS transistor is connected between the second resistor R6 and the third resistor R7. The source of the PMOS transistor is connected to the power supply port +3.3V of the interface module 20. The drain of the first PMOS transistor Q2 is connected to the power supply port VCC_3.3V of the brightness sensor 402 and the TOF ranging sensor 403. The first capacitor C1 is connected in parallel across the third resistor R7. One end of the second capacitor C2 is connected to the drain of the first PMOS transistor Q2, and the other end is grounded.

[0030] In practical applications, when the VCC_CTL signal output from the main control module of the display is high, the first transistor Q1 is turned on, which in turn turns on the first PMOS transistor Q2. This powers the VCC_3.3V power supply to the brightness sensor 402 and the TOF distance sensor 403, causing them to operate. Conversely, when the VCC_CTL signal is low, the first transistor Q1 is turned off, which in turn turns off the first PMOS transistor Q2. This disconnects the VCC_3.3V power supply to the brightness sensor 402 and the TOF distance sensor 403, preventing them from operating. The main control module controls the brightness sensor 402 and the TOF distance sensor 403 by controlling the level of the VCC_CTL signal output to the control port.

[0031] In one embodiment, reference is made to Figure 2 The LED module 30 includes light-emitting diodes (LEDs), and the interface module 20 has GPIO ports. The anodes of the LEDs are connected to the GPIO ports of the interface module 20, and the cathodes are grounded. Specifically, the interface module 20 has GPIO ports GPIO3 and GPIO4, and the LED module 30 is composed of LEDs. One or more LEDs can be used; in this embodiment, two LEDs, LED1 and LED2, are used. The anodes of LED1 and LED2 are connected to the GPIO ports GPIO3 and GPIO4 of the interface module 20, and the cathodes of LED1 and LED2 are grounded. After the interface module 20 is connected to the display, the GPIO ports GPIO3 and GPIO4 of the interface module 20 are connected to the GPIO ports of the display's main control module (such as a SoC). In practical applications, the display's main control module can control the on / off state of LEDs LED1 and LED2 by controlling the GPIO outputs, thus providing status indication. In summary, the multi-functional sensor adapter board of this application integrates the LED module and the sensor module into a single board. By creating an isolation notch on one side of the board, the board is divided into an adjacent first board and a second board to house the LED module and the sensor module. The isolation notch is installed in conjunction with the display housing, which can isolate the LED module and the sensor module from each other, avoid mutual interference between the LED module and the sensor module, reduce the space occupied by the display, and simplify the wiring connection.

[0032] See Figure 3The present invention also provides a display 200, which includes a housing 210 and a multi-functional sensor adapter board 100 as described in the above embodiments. The multi-functional sensor adapter board 100 is disposed in the housing 210, wherein the housing 210 is provided with a non-transparent structural member 2101, which passes through the isolation notch 101 of the multi-functional sensor adapter board 100 to block the LED module 30 and the sensor module 40 of the multi-functional sensor adapter board 100.

[0033] In a specific implementation, the display 200 includes a housing 210 and a multi-functional sensor adapter board 100. It may also include components such as a screen. Since the specific structure and working principle of the multi-functional sensor adapter board 100 have been described in detail in the preceding description, they will not be repeated here for the sake of brevity. The multi-functional sensor adapter board 100 is housed within the housing 210. The multi-functional sensor 41 is installed in conjunction with the housing 210 through the isolation notch 101 on the board 10. During installation, the LED module 30 and the sensor module 40 of the multi-functional sensor adapter board 100 are exposed outside the housing 210 of the display 200. Specifically, a non-transparent structural component 2101 is provided in the housing 210. The non-transparent structural component 2101 is designed with an opaque material and can be a baffle structure. Its shape matches the isolation notch 101 on the board 10. The non-transparent structural component 2101 passes through the isolation notch 101, blocking the LED module 30 and the sensor module 40 of the multi-functional sensor adapter board 100. This places the LED module 30 and the sensor module 40 on opposite sides of the isolation notch 101 and isolates them from each other by the non-transparent structural component 2101. In practical applications, when the LED module 30 is working, the light emitted is blocked by the non-transparent structural component 2101, thus preventing it from illuminating the sensor module 40 and causing interference. This makes the sensor module 40 work more stably and reliably. Furthermore, since the LED module 30 and the sensor module 40 are integrated on a single board 10, the entire adapter board does not occupy too much space in the housing 210 of the display 200, allowing for a smaller display size design.

[0034] Furthermore, referring to Figure 3The system also includes a main control module 220, which is connected to the interface module 20 of the multi-functional sensor adapter board 100 via a cable. In a specific implementation, the display 200 further includes the main control module 220, which is the control core of the display 200. The main control module 220 specifically adopts a System on Chip (SOC) and is used for signal processing, decoding, and system operation control of the display 200 system. The main control module 220 is connected to the interface module 20 of the multi-functional sensor adapter board 100 via a cable, thereby establishing communication with the multi-functional sensor adapter board 100 and enabling the functions of sensor 41, such as automatically adjusting screen brightness according to ambient light, controlling the screen with an infrared joystick, and automatically turning the screen on and off. Since the LED module 30 and the sensor module 40 of the multi-functional sensor adapter board 100 share the same interface module 20, the connection between the adapter board and the main control module 220 can be achieved by plugging and unplugging the cable once, making the wiring simpler.

[0035] In summary, the display of this application, by adopting the multi-functional sensor adapter board provided in the above embodiments, can realize various sensor functions, and the size of the display can be designed to be smaller, meeting the user's small size requirements.
