Product Features

1. Customizable Text and Image Display
Using the dedicated application, downloadable from [Santek Direct Shop → Contact → Product Support → 4.2” 4 Color E-paper Display → Download (EZ Sign 1.2.0.0)], you can easily change the display text. Up to 5 text or image entries can be registered, and any fonts installed on your PC are usable. Not only text but also images can be displayed, allowing you to create and showcase your preferred designs.

2. Simple Operation
The device is designed for maximum ease-of-use and efficiency, minimizing stress and confusion. Switching the display is as simple as pressing the button on the right side of the unit, enabling quick and intuitive use.

3. Low Power Consumption & Long Operation
Leveraging the low power consumption of electronic paper (E-paper), the display can maintain content continuously for long periods. The device does not require daily charging, as the screen retains images without power after updating. No ON/OFF operation is needed.

4. Built-In Stand Function
The unit includes a built-in stand, allowing placement on reception counters, desks, or flat surfaces. The stand can also be folded flat, enabling attachment to doors, whiteboards, or refrigerators at home or in the office.

5. 4-Color Display
The display supports black, red, yellow, and white for both text and images. Colors can be selected to attract attention or highlight important information, making the display easily visible even from a distance.

Practical Use Cases

• Notes for short absences at work

• Information display at hotels or accommodations

• Reception desk signage

• Messages from children

• Family messages

• Entrance signage

The Santek EZ Sign was developed as a new interactive tool for situations where you want to convey information quickly, whether at home or in the workplace. For example, during telework, you can display "Working" when you don’t want to be disturbed, or leave detailed messages like “Away / Visiting Mr. X / Back around 1 PM.” At home, you can leave notes for children or even scan and display their drawings permanently.
