E-Paper Refresh Technologies

What is E-Paper Refresh Technology?

E-Paper refresh technology combines hardware, advanced algorithms, and system-level optimizations to control how quickly and precisely ink particles move, align, and retain images on the screen. Designed to overcome slow refresh rates and ghosting in traditional ePaper, it improves smoothness while keeping eye comfort and low power benefits. Today, refresh solutions range from full and partial updates to fast-refresh modes, reaching up to 60Hz continuous video playback.

Hardware

thinner FPL films, high charge-mobility materials, and optimized refresh ICs for faster, uniform, and ghost-free screen updates.

Algorithms

waveform compression, partial refresh + historical frame compensation, Auto-Clear for ghost suppression, and temperature LUT adjustments.

System

dynamic content-based refresh modes (text, images, video) switching between GC16, DU, A2 to balance speed and visual quality.

Types of E-Paper Refresh Technology

Refresh Type	Core Principle	Key Advantages	Limitations
Full Refresh	Refreshes the entire screen at once, regardless of how much content changes.	Produces the cleanest display with almost no ghosting, like a brand-new page.	Slow speed, visible flashing (“black screen”), higher power consumption.
Partial Refresh	Refreshes only the parts of the screen where content changes.	Faster, more power-efficient, and less flicker, making reading smoother.	May leave light ghosting after long use, requiring occasional full refresh.
Fast Refresh (e.g., BSR)	Uses optimized waveforms and algorithms to accelerate refresh speed.	Enables smoother web browsing, handwriting, and even video playback with minimal flicker.	Slight loss in sharpness; text edges may appear less crisp than in full clarity mode.
Smart/Adaptive Refresh	Dynamically selects the best refresh mode based on content type (text, charts, or dynamic data).	Seamlessly balances clarity and speed without manual switching.	Requires complex algorithms and advanced hardware, often limited to premium devices.
