[0022] The specific principle of the present invention is described in detail below: 1. Display of power supply working parameters, including: 1. Voltage display: The input and output voltages are detected in real time and displayed on the display. With the built-in adapter voltage protection solution, if the voltage fluctuates abnormally and exceeds the safe output range, intelligent disposal can be carried out to avoid damage to the equipment. Disposal plan: a. The adapter takes corresponding measures in real time; b. The user takes corresponding measures after the alarm.

[0023] 2. Current display: The input and output currents are detected in real time and displayed on the display screen. With the built-in power current protection solution, if the current is too large or too small, intelligent disposal can be carried out to avoid damage to the equipment. Disposal plan: a. The adapter takes corresponding measures in real time; b. The user takes corresponding measures after the alarm.

[0024] 3. Real-time power display and power supply working efficiency display; based on the detected real-time voltage / current, calculate the real-time power and efficiency and output them on the display screen.

[0025] 4. Working status display: According to the output results of the adapter, text or graphic prompts are output on the display screen in real time, such as "normal working", "charging", "fault", etc., to inform the user of the status of the power adapter more clearly, and the prompt information is clearer.

[0026] 5. Device operating temperature display: Built-in temperature sensor detects the operating temperature of high-temperature devices in real time, and through the built-in over-temperature protection solution, it intelligently adjusts the output of the adapter and reminds the user in real time.

[0027] 2. Electronic calendar and electronic alarm clock display: (1) Basic functions include the following: 1. Calendar display: Ensure that the desk calendar can accurately display information such as the Gregorian calendar, lunar calendar, holidays, etc., and that date switching is smooth and correct. Support multiple calendar views, such as day view, week view, month view, etc., view schedules according to different needs, and choose the appropriate view mode according to your daily usage habits. 2. Schedule management: You can add, edit, and delete schedules on the desk calendar, set reminder times (including single reminders, repeated reminders, etc.), and synchronize schedules with mobile phones or other devices so that you can view and manage them anytime, anywhere. For example, some smart desk calendars support voice input of schedules, which is more convenient to operate. 3. Clock function: Accurate clock display is a basic requirement, and supports functions such as world clock, countdown, and stopwatch.

[0028] (2) The electronic calendar and electronic alarm clock display have corresponding operational convenience: 1. Interaction mode: Touch operation, key operation and voice operation can be used. Touch operation is more intuitive and convenient, but the screen sensitivity and response speed must be good enough; key operation is relatively simple and easy to understand, suitable for users who are not accustomed to touch operation; voice operation is more convenient, especially when both hands are busy, you can complete the operation through voice commands, but the accuracy of voice recognition must be high. 2. Connection and setting: The connection methods include Wi-Fi connection, Bluetooth connection and USB connection. Wi-Fi connection can realize remote control and data synchronization, but a stable network environment is required; Bluetooth connection is suitable for close-range connection with mobile phones and other devices; USB connection is mainly used for data transmission. 3. Personalized settings of electronic calendar and electronic alarm clock display: 1. Background and theme: Choose a smart calendar that can change the background picture, theme color or style, and you can personalize it according to your preferences and usage scenarios to increase the beauty and fun of the calendar. 2. Customized reminders: In addition to regular schedule reminders, it supports customized reminders, such as birthday reminders, anniversary reminders, repayment reminders, etc. You can set the corresponding reminder content and method according to your needs.

[0029] (3) Additional functions include weather display: If the desk calendar can display real-time weather information, weather forecast, etc., it will be very helpful for daily travel and activity arrangements.

[0030] 3. Intelligent switching display interface: 1. The adapter is not connected to the power supply: only the electronic calendar is displayed; 2. The adapter is not connected to the device: the electronic calendar / electronic clock is displayed; 3. The adapter is connected to the device: while displaying the electronic calendar / electronic clock, the output display of the adapter's working parameters is added.

[0031] Furthermore, screen size and resolution: select the appropriate screen size and display resolution based on the placement and actual functional requirements.

[0032] Furthermore, the display screen can be a liquid crystal display (LCD), an organic light-emitting diode display (OLED), and an electronic ink screen (E-ink), etc. LCD / OLED displays have bright colors and good display effects, but are relatively power-consuming; the electronic ink screen has a display effect similar to that of a paper book, is not dazzling, and can be clearly seen even in the sun.

[0033] The present invention adopts the above technical solution, breaking the existing power adapter that only provides a simple device power supply function, and equips the power adapter with a display screen, which can display the working parameters of the adapter, can be used as an electronic desk calendar, wirelessly charge mobile phones, and provide signal conversion and other functions.
