In the above embodiments, by using the main board of the smart mobile terminal (e.g., smart phone) as the auxiliary main board 204 of the display device 10, on one hand, a way to recycle the obsolete smart mobile terminal is provided; on the other hand, even if the smart mobile terminal is eliminated, the performance of the main board (including the processing chip mounted thereon) greatly exceeds the performance of the processor of the conventional display device, so the performance of the display device 10 is greatly improved.

In the above embodiment, the auxiliary main board 204 may be a eliminated main board of the smart mobile terminal, for example, the eliminated main board of the smart mobile terminal together with the processing chip, the sensor, and other components thereon may be used as the auxiliary main board 204 in the display device 10. The auxiliary main board 204 may also be a factory-new main board of the intelligent mobile terminal.

In the above embodiment, the auxiliary main board 204 is configured to provide the following functions:

and (3) storage expansion: namely, the main board of the intelligent mobile terminal is used as an expansion memory;

data acceleration: the data processing load of a display device main board and a processor is shared by utilizing the excellent data processing capacity of the intelligent mobile terminal main board (including the processor);

and (3) separating an air-drop screen: the main board of the intelligent mobile terminal has a WIFI function, and by starting the Station mode, the main board accesses an AP (Access Point) to be connected, can obtain display content, and transmits the display content to the main board of the display device 10 through the electric connector 203 and displays the display content to a user;

and OTA connection: the main board of the smart phone has the OTA function, and can access the Internet through operator services such as 3G, 4G, 5G and the like to enjoy network services. The OTA data is acquired by the motherboard of the smart phone, transmitted to the motherboard of the display device 10 through the electrical connector 203 and displayed to the user, and the instruction sent by the user and related to the OTA is also transmitted to the motherboard of the smart phone through the motherboard of the display device 10 and the electrical connector 203.

In one embodiment, the auxiliary motherboard 204 and the motherboard of the display device 10 may operate independently, and the operation result on one of the motherboards is displayed on the display screen according to the requirement and the preset system logic. As another embodiment, the auxiliary main board 204 is only responsible for data operation and data storage, and feeds back the operation result to the main board of the display device 10 or transmits the stored data to the main board of the display device 10.

In the above embodiment, the display screen module 101 may be an LED screen, or an LCD screen with a backlight module. The housing 102 is provided with circuit components such as a power board and a main board, and the main board is provided with important elements such as the processor of the display device 10. A power line, an audio/video interface, a USB interface, and the like are provided on the periphery of the housing 102 (including the side edge and the rear cover of the housing 102).

Further, the display device 10 of the embodiment of the present application further includes an auxiliary motherboard mounting box 103, where the auxiliary motherboard mounting box 103 includes:

a case 206 having an opening (not shown);

a printed circuit board 201 mounted in the case 206, the printed circuit board 201 being provided with a plurality of printed lines (not shown);

the jig 202 is mounted on the printed circuit board 201 and configured to fix the auxiliary motherboard 204, the auxiliary motherboard 204 is electrically connected to one end of the printed circuit, the other end of the printed circuit is connected to the electrical connector 203, and the electrical connector 203 is disposed at the opening of the box 206 and serves as an input/output interface of the auxiliary motherboard mounting box 103.

In the above embodiment, the electrical connector 203 disposed at the box opening enables the auxiliary motherboard mounting box 103 to be quickly connected to and detached from the display device 10. Since the auxiliary board mounting box 103 supports hot plug, the auxiliary board 204 only serves as an auxiliary device and cannot acquire the right of ownership of the display apparatus 10. In addition to utilizing the insertion and extraction force between the electrical connector 203 and the housing 102, an additional locking structure may be provided to achieve further fixation between the auxiliary motherboard mounting box 103 and the housing 102. The locking structure may be a screw or a snap structure.

For convenience of popularization, the size of the box 206 may refer to the size of an OPS (Open plug capable Specification) housing, and the selection and location of the electrical connector 203 may also refer to the OPS standard. In addition, in order to adapt to the trend of ultra-thinning products, the design of the auxiliary main board mounting box 103 can be further optimized by referring to the size of the smart phone on the basis of the reference of the standard size of the OPS, so that the thickness of the auxiliary main board mounting box does not exceed 10 millimeters (mm).

In specific implementation, the auxiliary main board 204 may be fixed on the fixture 202, and then the fixture 202 and the auxiliary main board 204 thereon are fixed on the printed circuit board 201 by fastening methods such as screws and fastening structures, and the printed circuit board 201 and the fixture 202 and the auxiliary main board 204 thereon are fixed on the box 206 by fastening methods such as screws and fastening structures.

Further, the box body 206 of the auxiliary main board mounting box 103 according to the embodiment of the present application may be assembled by two or more shells, and the shells may be assembled and disassembled quickly by using screws and/or a snap structure. The auxiliary motherboard mounting box 103 may further include physical keys, such as a switch key and a volume key, which may completely correspond to the key functions of the smart mobile terminal (e.g., a mobile phone) to control the auxiliary motherboard 204.

In one embodiment of the fixture 202, the fixture 202 is provided with a mounting groove (not shown) matching the shape of the auxiliary main board 204 and configured to mount the auxiliary main board 204. As another embodiment of the jig 202, as shown in fig. 3, the jig 202 is provided with a plurality of clips 301, each clip 301 includes a spring, one end of the spring is fixedly installed, the other end of the spring is configured to elastically press against a side portion of the auxiliary main plate 204, and the plurality of clips 301 elastically press against different sides of the auxiliary main plate 204. Due to the arrangement of the card holder 301, the jig 202 can be matched with and installed with the auxiliary main boards 204 of different manufacturers and different models/sizes, so that the cost is reduced, and the universality is improved.

Further, in the display device 10 of the embodiment of the application, the auxiliary main board 204 is electrically connected to one end of the printed circuit board through a conductive wire. The auxiliary main board 204 and the printed circuit board 201 are connected by wires, so that a circuit structure can be prevented from being arranged in the jig 202, and the structure of the jig 202 can be simplified. That is, the jig 202 in the embodiment of the present application only plays a role of fixing, and does not have an electrical connection function. The conductive wires may be flexible (bendable) discrete cables, or may be a flexible circuit board (FPC) 205.

The connector of the auxiliary main board 204 taken from the intelligent mobile terminal has various communication interfaces, such as a USB interface, a speaker interface, a motor interface, an earphone interface, a power interface, an I/O interface, etc., but when the display device 10 works, the auxiliary main board 204 only needs to be connected with the power interface and the USB interface, so that a power interface line and a USB interface line only need to be reserved on the flexible circuit board 205, wherein the USB interface line is used for communication between the auxiliary main board 204 and the printed circuit board 201, and the power interface line is used for supplying power for the work of the auxiliary main board 204.

Only one flexible circuit board 205 is shown in the figure, but actually, there may be a plurality of flexible circuit boards 205, which are used to transmit electric signals such as USB signals, battery signals, key signals, and touch signals. In order to facilitate the connection between the flexible circuit board 205 and the auxiliary main board 204, the printed circuit board 201, etc., connectors may be disposed at two ends of the flexible circuit board 205, and mating connectors may be disposed at corresponding positions of the auxiliary main board 204 and the printed circuit board 201. The connectors at the two ends of the flexible circuit board 205 are matched with the mating connectors, and BTB or ZIF type connectors can be adopted.

In the above embodiment, the electrical connector 203 may be a USB connector. The electrical connector 203, as an element for connecting the display device housing 102 (e.g., a processor) and the auxiliary motherboard mounting box 103, mainly provides transmission in terms of power and signals, and a USB connector can be well adapted to this requirement. Since the main board and the auxiliary main board 204 of the display device 10 both use USB interfaces, all data (including but not limited to audio/video data, network data, control data, etc.) must be converted into data types supported by the USB protocol, which is not only beneficial to popularization, but also beneficial to corresponding software development and cost reduction. As another embodiment, the electrical connector 203 may be an OPS connector, and correspondingly, the main board of the display device 10 also uses an OPS interface.

As an embodiment for realizing the connection between the display device 10 and the auxiliary main board mounting box 103, a second connector (not shown) is provided on the surface of the housing 102; the auxiliary main board mounting box 103 is fixed and electrically connected to the housing 102 by the mating and abutting of the electrical connector 203 and the second connector. As another embodiment for realizing the connection between the display device 10 and the auxiliary main board mounting box 103, a second connector (not shown) is provided on the surface of the housing 102; the auxiliary motherboard mounting box 103 is connected to the housing 102 by a cable connector assembly (not shown) including a third connector configured to mate with the electrical connector 203, a fourth connector configured to mate with the second connector, and a cable connected between the third connector and the fourth connector.

The second connector, the third connector, the fourth connector, and the like may also be USB connectors, but they may not necessarily be Type-C Type USB connectors since compatibility with the flip-flop insertion capability does not need to be considered. The high-speed data can be transmitted by using pins such as SSRX +, SSRX-, SSTX +, SSTX-, DP, DM and the like, the control signals and the low-speed data can be transmitted by using pins such as CC1, CC2, SBU1, SBU2 and the like, and the power supply can be transmitted by using pins such as VBUS, GND and the like. In order to enable the auxiliary motherboard box 103 to support hot plug function, the plug detection can be implemented by using the variation of the high and low levels of the CC1 pin, for example, the printed circuit board 201 can be connected to a pull-down resistor, and when the CC1 pin detects the low level, it indicates that the auxiliary motherboard box 103 is inserted into the housing 102 of the display device 10.

Further, in the display device 10 of the embodiment of the present application, in addition to the electrical connector 203 and the auxiliary main board 204, the printed circuit board 201 is further mounted with a sensor (e.g., a temperature and humidity sensor), a communication module and/or a processing unit. The arrangement of the above-described sensors, communication module, processing unit, and the like is advantageous for expanding the use of the display device 10.
