Description

Technical Field

[0002] A receiver is a device or apparatus whose main function is to receive, pick up or capture a specific signal, information or energy. Different types of receivers are designed to receive various types of signals such as radio waves, light waves, sound waves, etc. These signals are converted into a usable form by the receiver so that we can further process and utilize them;

[0003] Most existing receivers are small electronic devices with a USB interface, which are used as a "bridge" device to connect a host device (such as a computer host, tablet computer, etc.) that does not have a wireless connection module to a wireless external device (such as a wireless mouse, wireless keyboard, etc.);

[0004] For example, a wireless receiver with publication number CN213026813U is used for wireless connection between a wireless input device and a computer, including a PCB board, an insulating shell, a first interface structure and a second interface structure. At least part of the structure of the PCB board is arranged in the insulating shell. The first interface structure forms a first USB interface, and the second interface structure forms a second USB interface. The first USB interface and the second USB interface are different types of interfaces, which are respectively used to electrically connect the PCB board of the receiver to different interfaces of the computer. The orientation of the first USB interface is perpendicular to the orientation of the second USB interface. The wireless receiver has both the first USB interface and the second USB interface, and the types of these two interfaces are different, which enhances the product adaptability of the wireless receiver. When plugged into a computer, the wireless receiver requires less external space.

[0005] The inventors have found that the existing receivers cannot display the relevant information of connecting to external devices, resulting in that when problems occur in the connection between the external device and the host device, the user cannot easily find the cause of the problem, which affects the user experience.

[0006] In view of this, the utility model provides a receiver with a screen to solve the above problems. Utility Model Content
