The display device provided by the utility model can be applied to a device system. Fig. 1 is a schematic diagram of an equipment system provided in the present invention, and as shown in fig. 1, the equipment system includes: a display device 100 and an external device 200. The external device 200 is plugged through the audio interface 110 in the display device to realize information interaction between the external device 200 and the display device 100.
If the external device 200 is an infrared receiver, the infrared receiver can receive infrared data transmitted from the outside, for example, an infrared control signal sent by an infrared remote controller, and then the infrared data can be transmitted to a processor in the display device 100 through the infrared receiver, so as to control the display device through the infrared remote controller. If the external device 200 is an audio device, audio data transmission may be implemented, for example, the processor sends the audio data to the audio device and/or the processor receives the audio data transmitted by the audio device. The infrared receiver and the plug-in part of the audio device, i.e. the plug, are of the same shape and can be plugged into the audio interface 110 in the display device.
In the practical application process of the equipment system provided by the utility model, if the display equipment does not have the infrared data transmission function, the first pin of the processor in the display equipment can be connected with one conductive pin of the audio interface, and the second pin of the processor is connected with the functional pin of the audio interface through the electronic selection switch, so that the audio data transmission can be realized through the audio interface when the first pin of the processor is in a first level state, and the infrared data transmission can be realized through the audio interface when the second pin of the processor is in a second level state, namely, the transmission of the audio data can be realized through the audio interface, and the transmission of the infrared data can also be realized.
In the existing solutions, if the infrared data transmission function of the device needs to be implemented, an infrared receiver is usually integrated in the display device, and meanwhile, an adapting hole needs to be formed on the housing of the device, which undoubtedly increases the hardware cost of the device and the design difficulty of the appearance of the display device. If a user needs to realize infrared data transmission of the equipment, for example, when the infrared data is used for controlling the display equipment, the infrared data transmission of the equipment can be carried out only by taking the infrared receiver as external equipment and inserting the infrared receiver into an audio interface of the display equipment, so that the infrared receiver does not need to be integrated in the display equipment, and the shell does not need to be improved by an adaptive hole, thereby effectively reducing the hardware cost and the appearance design difficulty. If the user does not need to carry out infrared data transmission and needs to carry out audio data transmission, the user only needs to take the audio equipment as external equipment to be plugged in the audio interface of the display equipment. Compared with the existing scheme, the equipment system provided by the utility model can respectively carry out audio data transmission and infrared data transmission aiming at different external equipment through the audio interface of the display equipment, does not need to add an additional infrared receiver in the display equipment, and does not need to change the appearance of the display equipment, so that the display equipment has infrared data transmission capacity, namely, the expansion capacity of the display equipment is enhanced, and different requirements of users can be facilitated.
An exemplary explanation of a display device 100 provided by the present invention is as follows with reference to the accompanying drawings. Fig. 2 is a schematic structural diagram of a display device according to an embodiment of the present invention, and as shown in fig. 2, the display device 100 includes: a processor 120, an electronic selector switch 130, and an audio interface 110.
The audio interface 110 comprises a conductive pin 111 and a functional pin 112, wherein the conductive pin 111 comprises two conductive pins, and the two conductive pins are oppositely arranged. The first pin 121 of the processor may be connected to any of the two conductive pins of the audio interface and the second pin 122 of the processor is connected to the functional pin 112 of the audio interface via an electronic selection switch 130. The audio interface may be, for example, an earphone interface, and the audio interface has a left channel pin, a right channel pin, a microphone pin, and a ground pin, wherein the conductive pin is the microphone pin, and the functional pins are the left channel pin and the right channel pin.
Specifically, the first pin 121 of the processor is connected to one conductive pin 111a of the audio interface, and in this case, the conductive pin 111a is used to identify the type of the external device 200 plugged into the audio interface 110. Aiming at different external equipment, the pins corresponding to the conductive pins on the plugging component are different in material, and the pins made of different materials are different in conductive performance. For example, for an audio device, the material of the pins corresponding to the conductive pins on the plugging component may be conductive, that is, conductive pins, and for an infrared receiver, the material of the pins corresponding to the conductive pins on the plugging component may be non-conductive, that is, non-conductive pins. Wherein, the pins corresponding to the conductive pins on the plug part refer to: pins that contact the conductive pins when the plug member is inserted into the audio interface.
Therefore, when the plug part made of different materials is inserted into the audio interface, the level state of one conductive pin 111a of the audio interface can be made different, and since the first pin 121 of the processor is connected with the one conductive pin 111a of the audio interface, the level state of the first pin 121 of the processor is made different, the processor can determine the type of the external device plugged into the audio interface based on the level state of the first pin.
If the first pin 121 of the processor 120 is in the first level state, the processor can determine that the external device 200 plugged in the audio interface is an audio device, and the processor 120 can perform audio data transmission through the electronic selection switch 130 and the audio interface 110. Specifically, when the first pin 121 of the processor 120 is in the first level state, the processor 120 may control the electronic selection switch 130 to turn on the transmission switch of the audio data, turn off the infrared data transmission switch, and enable the audio data transmission channel between the processor 120 and the audio interface to be connected, so as to transmit the audio data to the function pin 112 of the audio interface 110, and enable the audio data transmission between the processor 120 and the audio interface 110.
If the first pin 121 of the processor 120 is in the second level state, the processor can determine that the external device 200 plugged in the audio interface is an infrared receiver, and the processor 120 can perform infrared data transmission through the electronic selection switch 130 and the audio interface 110. Specifically, an infrared control signal sent by the infrared remote controller is transmitted to the processor 120 through the infrared receiver, then the first pin 121 of the processor 120 is in the second level state, and the processor 120 can control the electronic selection switch 130 to turn off the transmission switch of the audio data, turn on the infrared data transmission switch, and achieve communication between the processor 120 and the infrared data transmission channel, so as to transmit the infrared data to the function pin 112 of the audio interface 110, and achieve infrared data transmission between the processor 120 and the audio interface 110.
In summary, the present invention provides a display device, which comprises a processor, an electronic selection switch and an audio interface, wherein a first pin of the processor is connected to a conductive pin of the audio interface, a second pin of the processor is connected to a functional pin of the audio interface through the electronic selection switch, the processor detects a level state of the conductive pin of the audio interface through the first pin, and determines whether an external device connected to the audio interface is an audio device or an infrared receiver by determining the level state, and further, the second pin of the processor selects a corresponding data transmission channel through the electronic selection switch to perform data transmission on corresponding audio data or infrared data, the display device enables the audio interface to transmit not only audio data but also infrared data through function expansion of the existing audio interface, and a user can select the display device according to needs, if the user need not to carry out infrared data transmission, and need carry out audio data transmission, then only need with audio equipment as external equipment peg graft on display device's audio interface can, if the user is as the infrared data transmission that needs to realize equipment, for example when using infrared data control display device, only need with infrared receiver as external equipment peg graft at display device's audio interface, can carry out the infrared data transmission of equipment, both need not to integrate infrared receiver in display device, also need not to carry out the improvement of adaptation hole to the shell, hardware cost and appearance design degree of difficulty have effectively been reduced.
Further, on the basis of the structure of the display device shown in fig. 2, the first level state and the second level state of the first pin 121 of the processor 120 are further explained by a possible implementation example of the level state of the first pin 121 of the processor 120. When the external device 200 is plugged into the audio interface 110 of the display device, a conductive pin 111a of the audio interface 110 contacts a corresponding pin of the external device 200.
If the pin corresponding to the external device 200 is a conductive pin, and one conductive pin 111a of the audio interface 110 is in communication with the circuit of the pin corresponding to the external device 200, the level state of the first pin 121 of the processor 120 is a first level state. Specifically, if the external device 200 is an audio device, the corresponding pin of the external device 200 is a conductive pin.
If the pin corresponding to the external device 200 is a non-conductive pin and the circuit of the conductive pin 111a of the audio interface 110 and the pin corresponding to the external device 200 is disconnected, the level state of the first pin 121 of the processor 120 is the second level state. Specifically, if the external device is an infrared receiver, the corresponding pin of the external device 200 is a non-conductive pin.
According to the embodiment of the application, the conductive pin of the audio interface is in contact with the corresponding pin of the external device, and the level states of the first pin of the processor are different due to different conductive properties. The material of the pin corresponding to the conductive pin of the audio interface contacting the infrared receiver is non-conductive, that is, non-conductive, and the material of the pin corresponding to the conductive pin of the audio interface contacting the audio device is conductive, that is, conductive. Therefore, in the embodiment of the present application, the material of the pins contacting the conductive pins of the audio interface 110 is different, so that the level states of the first pin of the processor are different, and different external devices can be identified through different level states, thereby performing transmission of audio data or transmission of infrared data.

Therefore, when the first level state of the first pin 121 of the processor is a low level state, the external device 200 is an audio device, and the processor sequentially performs audio data transmission through the electronic selection switch 130 and the audio interface 110.
If one conductive pin 111a of the audio interface 110 of the display device 100 contacts a non-conductive pin corresponding to the external device 200, the external device 200 is an infrared receiver, the one conductive pin 111a and the other conductive pin 111b of the audio interface are not connected, the circuit is in an off state, and the first pin 121 of the processor 120 is connected to the preset power source 150 through the preset resistor 140, so that the level state of the first pin 121 of the processor 120 is a high level state. Therefore, when the second level state of the first pin 121 of the processor 120 is the high level state, the external device 200 is an infrared receiver, and the processor sequentially performs infrared data transmission through the electronic selection switch 130 and the audio interface 110.
