Features

Exceptional Readability: The display’s reflective properties ensure effortless legibility of text and images in different lighting environments.
Ultra-Low Power Usage: The E-Paper only consumes power during updates, leading to prolonged battery life and efficient energy use.
Wide Viewing Angles: Greater than 170 degrees, unaffected by light direction.
Flexibility and Portability: Allowing bending and curling for versatile applications.
Eye-Friendly and Heat-free: Eliminate glare, providing a comfortable viewing experience while remaining cool without generating heat.

The 1.54-inch E-paper Display offers a high-quality, low-power solution with a 200×200 resolution and a 1-bit black and white display. It features high contrast, high reflectance, ultra-wide viewing angle, ultra-low power consumption, and pure reflective mode, is ideal for e-readers, smart wearables, and portable devices. This bi-stable display operates in landscape and portrait modes, and is capable of commercial temperature range operation.

It is available in COG package IC thickness 280um and has an on-chip display RAM and waveform stored in On-chip OTP. The display also has a serial peripheral interface available, on-chip oscillator, and on-chip booster and regulator control for generating VCOM, Gate, and source driving voltage.

What is an E-Paper?

E-Paper, short for Electronic Paper, is a type of display technology that aims to mimic the appearance of traditional paper and ink. It’s designed to provide high contrast and readability in various lighting conditions, including direct sunlight, without the need for a backlight. E-Paper displays use tiny microcapsules containing charged particles suspended in a liquid to produce images. When an electric field is applied, the particles move to the top or bottom of the microcapsules, resulting in different shades or colors being visible to the viewer. E-Paper is often used in e-readers, electronic shelf labels, smartwatches, and other devices where energy efficiency and readability are essential.

Advantages Over Traditional Displays

E-paper displays offer advantages over traditional displays, including better readability like paper, visibility in sunlight, low energy consumption, thin design, wide viewing angles, and longer battery life. They are ideal for portable devices and environments where glare and power efficiency matter.
