[0020] The present invention will be explained in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0021] Figure 1 This is a schematic diagram of the structure of the present invention. Detailed Implementation

[0022] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be given below with reference to the accompanying drawings, which illustrate several embodiments of the present invention. However, the present invention can be implemented in different forms and is not limited to the embodiments described in the text. Rather, these embodiments are provided to make the disclosure of the present invention more thorough and complete.

[0023] Reference Figure 1 The present invention provides a wristwatch remote control display system comprising: Watch design: Main control chip: The ESP32S3 chip is selected, which has a dual-core processing capability of 240MHz, which can meet the needs of system operation and signal processing. It also has a built-in Bluetooth 5.0 module to support low-power Bluetooth communication.

[0024] Touchscreen module: A 1.46-inch circular capacitive touchscreen with a resolution of 412×412 pixels is used. The screen and touch control chip is the SPD2010, and the ESP32S3 chip refreshes the screen interface via the QSPI interface and acquires touch data via the IIC interface. Users can perform various operations through the touchscreen.

[0025] Bluetooth Module: Utilizing the built-in Bluetooth function of the ESP32S3 chip, the internal program is used in GATT client mode. It can scan for BLE devices and connect to multiple devices, supporting simultaneous remote control of multiple displays from a single watch. Communication with external devices is achieved through a Bluetooth antenna located on the watch band to ensure good signal transmission.

[0026] Power management module: It uses a 3.7V, 300mAh rechargeable lithium battery, equipped with a micro USB charging port and a power management chip. When there is no touch operation or Bluetooth data interaction for more than 10 seconds, the device turns off the screen and enters a low-power mode (the set time can be configured as needed, and is preferably 10 seconds in this embodiment). Through low-power design and power management strategy, the watch can achieve a battery life of more than 7 days under normal use.

[0027] User Interface: The device runs the LVGL lightweight general-purpose graphics library and features a simple and intuitive user interface on the touchscreen, including a menu bar. Users can access corresponding control pages by clicking different options in the menu bar, such as the display configuration interface, brightness adjustment page, and signal source switching page. On each control page, virtual buttons and sliders facilitate user operation. When the watch is connected to multiple displays, the user interface provides a device list view, allowing users to select the display they need to control.

[0028] Display end: Bluetooth receiver module: Matches the Bluetooth module on the watch, receives control commands from the watch, and converts them into a signal format that the display can recognize. This module also supports Bluetooth 5.0, ensuring communication compatibility and stability with the watch.

[0029] The signal processing and conversion module can be a driver running on the main processor inside the display, or a dedicated microcontroller, used to parse Bluetooth commands and convert them into control bus signals for the display (such as I2C, USB HID commands, etc.).

[0030] Continue to refer to Figure 1 The present invention also provides a method for controlling a wristwatch remote control display, comprising the following steps: Step S1: Initialize the watch system, including power, touchscreen, Bluetooth and user interface initialization; Step S2: The watch searches for and connects to the display device via Bluetooth; Step S3: The user performs an operation on the touchscreen of the wristwatch, generates control commands, and sends them to the display via Bluetooth; Step S4: The display receives and parses the control commands, and executes the corresponding display control operations; Step S5: The display terminal feeds back the operation result or status information to the watch terminal and displays it on the watch terminal interface.

[0031] The control commands include, but are not limited to, brightness adjustment, signal source switching, resolution adjustment, and menu control.

[0032] In step S2, the wristwatch can connect to multiple displays simultaneously and can send control commands individually or uniformly.

[0033] The watch automatically enters a low-power mode after detecting no touch operation or no Bluetooth data transmission for a set time, and is then woken up by touch or Bluetooth data.

[0034] The specific process of the wristwatch software of this invention is as follows: 1. System Initialization: After the watch starts up, it performs self-tests and initialization operations to ensure the system is in normal working condition. Initialization includes power initialization, touch initialization, LCD screen initialization, backlight PWM initialization, LVGL initialization, Bluetooth initialization, and RTOS initialization.

[0035] 2. Bluetooth Task: The watch searches for nearby display devices via Bluetooth module. The user selects the display device to connect to on the watch's user interface. The watch and the display's Bluetooth module establish a stable Bluetooth connection, and Bluetooth data communication begins after the connection is successful.

[0036] 3. Control Command Generation and Transmission: Users operate the touchscreen on the wristwatch, such as clicking virtual buttons or swiping the screen. The touchscreen module converts these touch actions into corresponding control command signals, which are then transmitted to the display via the Bluetooth module of the ESP32S3 chip. Upon receiving the control commands from the wristwatch, the display's Bluetooth receiver module parses and converts the commands, generating signals that the display's internal control system can execute. These signals are then sent to the display's control circuitry, enabling remote control of the display.

[0037] 4. Feedback Information Reception and Display: After performing a control operation, the display sends feedback information such as the operation result or the current status of the display back to the wristwatch via Bluetooth. After receiving and parsing the feedback information, the wristwatch displays the corresponding prompts on the user interface, such as operation success, current brightness value, signal source status, etc., so that the user can understand the operation result and the status of the display in a timely manner.

[0038] 5. Power Management Task: When there is no touch action or Bluetooth data interaction for 10 seconds, the backlight is turned off and low power mode is entered. It can be woken up by Bluetooth data or touch interruption.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
