Special Features

    
    Our product boasts distinctive features that set it apart from the competition    
    ESP32-L is an E-Paper display driver board based on ESP32, and ESP32 is a serial port WiFi+BT module. Compared with ESP8266, it adds Bluetooth function, and its processor speed is faster and power consumption is lower. Its internal integrated MCU can realize serial communication between single-chip computers; this module is easy to learn, small in size, and convenient for embedded development. ESP32 is specially designed for mobile devices, wearable electronic products and IoT applications, and achieves ultra-low power consumption through a number of proprietary technologies.

The power saving mode of ESP32 is suitable for various low-power application scenarios. We can understand the ESP32 module as a single-chip microcomputer with WiFi and BT functions. When we use our own single-chip microcomputer to control, we only need to let the two single-chip microcomputers communicate with each other, the instructions are the same, and the corresponding operations are performed

Every day is Earth Day

 

 

You don't need to be an environmental scientist to make sustainable choices.
At Good Display, we passionately integrate sustainability into the production of e-paper.

 

 

 

 

 

 

Substitute for Paper Usage

Epaper provide a paper-like touch and reading experience, serving as a sustainable alternative to traditional paper and reducing environmental impact from deforestation and paper manufacturing.

Device Packaging
95% of this device's packaging is crafted from wood fiber-based materials sourced responsibly from managed forests or recycled sources.

Energy Efficiency
Epaper consumes minimal energy compared to conventional displays, reducing electricity bills and easing the demand on power plants, thereby lowering greenhouse gas emissions—a perfect choice for eco-conscious consumers.
