[0033] In order to make the objectives, features, and advantages of the present disclosure more obvious and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present disclosure.

[0034] In current electronic devices such as laptops, tablets, and mobile phones, interfaces such as HDMI, DP, and VGA are widely used. However, for HDMI, DP, VGA and other interfaces, the interface needs to be connected to the adapter board through a wire, and the adapter board is then connected to its processor. Finally, after the processor processes the signal, it is displayed on the display screen. In addition, from the perspective of the monitor, having too many reserved interfaces is gradually becoming a redundant design, resulting in higher development costs and greater design difficulties. Therefore, in this application, a display device that uniformly uses a Type-C port as the data interface is adopted, so that intermediate links such as the adapter board and connection wires in the monitor do not need to be set, and it can be directly connected to an electronic device that supports Type-C DP data transmission for display, thereby reducing costs.

[0035] The following introduces the display device and electronic device provided in this application with reference to the accompanying drawings.

[0036] As Figure 1 shown, this application provides a display device, which includes: a Universal Serial Bus Type-C (Type-C) interface module 1, a data processing module 2, and a display module 3. The Type-C interface module 1 and the display module 3 are respectively connected to the data processing module 2;

[0037] The Type-C interface module 1 is used to receive input data from an input device;

[0038] The data processing module 2 is used to process the input data to generate a video stream signal and send it to the display module 3 when receiving the input data from the Type-C interface module;

[0039] The display module 3 is used to receive the video stream signal and display the video.

[0040] It can be understood that in this application, the Type-C interface module 1 complies with the Type-C interface specification and can be used to supply power to the backend and transmit display data signals. The Type-C interface in this application is the external interface of the display device of this application, and mainly has two functions: one is to send the DP signal from the source end to the data processing module 2 at the backend; the other is to provide power supply to provide power support for the backend modules such as the data processing module 2 and the display module 3. It can be understood that one or more Type-C interfaces are set in this application for data transmission or power supply. The display module 3 in this application is a module that converts a digital display signal into an optical signal visible to the human eye. After receiving the video stream signal, the display module 3 converts the electrical signal into an optical signal for output.

[0041] The input device in this application can be an external device such as a host system, a USB flash drive, or a power adapter. The power adapter can provide power to other modules of the display device through a Type-C interface. For example, the power adapter provides power to the data processing module 2, the touch control module 4, and the display module 3 through the Type-C interface. The USB flash drive can provide a data stream to the display device through the Type-C interface.

[0042] The display device provided in this application receives the input voltage or input data of the input device through the Type-C interface module 1, and then the data processing module 2 processes the input data to generate a video stream signal, and the display module 3 displays the video stream signal. This application uniformly uses the same Tpye-C data interface, so there is no need to set up intermediate links such as a monitor transfer board and connection wires, and it can be directly connected to and displayed on an electronic device that supports tpye CDP data transmission, thereby reducing costs. The data processing module 2 in this application can use a time controller data decoding module. The timecontroller data decoding module in this application can directly obtain the DP signal transmitted by the Type-C interface module 1 and directly display it on the display module 3 after processing.

[0043] In some optional embodiments, the display device further includes: a touch control module 4, and the touch control module 4 is connected to the data processing module 2;

[0044] The touch control module 4 is used to periodically receive user touch commands;

[0045] The data processing module 2 is further used to, when receiving a touch command from the touch control module 4, send the touch command to the system end through the Type-C interface module 1.

[0046] It can be understood that the display device is connected to the system end through the Type-C interface module 1. The touch control module 4 can scan and detect the user's touch behavior to generate a touch command. When the data processing module 2 receives the touch command from the touch control module 4, it sends the touch command to the system end through the Type-C interface module 1.

[0047] In some optional embodiments, the display device further includes: an audio module 5, and the audio module 5 is connected to the data processing module 6;

[0048] The data processing module 6 is further used to decode the input data of the input device into an audio stream signal;

[0049] The audio module 5 is used to receive the audio stream signal and output audio.

[0050] It can be understood that the data processing module 2 in the present application adopts a time controller data decoding module, which can realize the operation, decoding and distribution of data such as display, audio and touch control. The data processing module 2 is responsible for communicating and handshaking with the system side to establish a device connection relationship. After the connection relationship is established, the data processing module 2 is responsible for the operation and distribution of data. It can directly decode the input data, i.e., the DP signal, sent by the tpye-C data interface into a video signal stream and an audio stream signal. The video signal stream is distributed to the backend display module 3 to display the picture, and the audio signal is distributed to the audio module 5 to emit sound. At the same time, the data processing module 2 in the present application is also used to drive the touch module 4 to scan. If user touch data is detected, it is transmitted to the system side. Therefore, in the present application, the Type-C interface module 1 and the time controller data decoding module capable of directly processing the DP signal input by the Type-C interface module 1 are adopted, so that no wires and adapter boards are required, and the structure is simpler.

[0051] The audio module 5 provided in the present application is used to convert the received audio signal into a sound audible to the human ear or provide an audio signal that can be received by the earphone.

[0052] As a specific implementation manner, as Figure 2 shown, in the present application, first, the system side and the display device are connected by wiring through the Type-C interface module 1, and then the display device is turned on through the switch module 6, that is, the display device starts to connect. The system side and the display device perform an identification and handshaking process. After the identification and handshaking are successful, the system side transmits the DP signal data to the display device through the type-C wiring. The data processing module 2 of the display device decodes and distributes the DP signal, the display screen outputs a video image, the audio module 5 outputs sound, and the touch module detects the user touch data and transmits it back to the system side. Finally, the switch is turned off and the Type-C interface module 1 is removed to end the display.

[0053] In some optional embodiments, the display device provided in the present application further includes:

[0054] A power supply module (not shown in the figure), which is used to input a voltage to the Type-C interface module to supply electrical energy to the display device.

[0055] Specifically, the power supply module provided in the present application can be converted by supplying power through the type-C interface using a power adapter, and is used to support the power supply of the backend display module and the touch module, etc., and match the current supply input through the type-C interface to the power supply required by the backend display module 3, the touch module 4 and other modules.

[0056] In some optional embodiments, the display device provided in the present application further includes:

[0057] A switch module 6 for controlling the on / off state of the display device;

[0058] One end of the switch module 6 is connected to the power supply module, and the other end of the switch module 6 is connected to the data processing module 2.

[0059] In this application, the switch module 6 is used to turn on and off the display screen. The switch module 6 is connected to the data processing module 2 and the power supply module. The switch module 6 can send a switch control signal to control the startup and shutdown of the display module 3.

[0060] In some optional embodiments, the display device provided in this application further includes: a circuit board,

[0061] The Type-C interface module 1, the data processing module 2, the power supply module, and the switch module 6 are arranged on the circuit board, and the display module 3 and the touch module 4 are connected to the circuit board through wires.

[0062] It can be understood that the audio module 5 in this application can be arranged on the circuit board or connected to the circuit board through wiring.

[0063] In some optional embodiments, the display device further includes:

[0064] An indication module 7 for indicating the on / off state of the display device;

[0065] The indication module 7 is connected to the data processing module 2.

[0066] It can be understood that after the display device is started through the switch module 6, the display device displays that it has been started through the indication module 7. The indication module 7 in this application can adopt an indicator light. In this application, the on / off state of the display device can be indicated by the lighting and extinguishing of the indicator light. The indicator light can be a red indicator light. When the display device is started, the red indicator light is on, and when the display device is turned off, the red indicator light is off.

[0067] In some optional embodiments, the touch module 4 is a resistive, capacitive, electromagnetic, infrared, or surface acoustic wave touch panel.

[0068] The touch module 4 is a resistive, capacitive, electromagnetic, infrared, or surface acoustic wave touch panel. In this application, the touch module 4 can cooperate with the data processing module 2 to detect voltage or capacitance changes generated by the user's touch thereon, or large magnetic field changes generated by the touch of an electromagnetic pen thereon, and use methods such as light source reception of blocked light and signal attenuation caused by the absorption of surface acoustic wave energy by the contact object to obtain the position of the touch point coordinates through calculation and judgment, which can be implemented by existing technologies and will not be elaborated herein.
