Why is GooDisplay E-Paper Faster to Refresh?
Three Key Technological Breakthroughs Leading the Industry in Refresh Speed
Optimized Fast-Refresh FPL
We rigorously select fast-refresh FPL films at the raw material level, laying a solid hardware foundation for high-speed performance.
Smart Temp-Controlled Drive
Our engineers optimize waveform files for different temperature ranges, ensuring excellent display quality even during rapid refresh cycles.
Chip-Level Integrated Solution
The optimized waveform files are built directly into the display driver chip. Plug and play—users can easily activate fast refresh mode with a simple code call!
