Is now a good time to upgrade your e-reader for better color quality?
E Ink has officially introduced its Kaleido 4 color ePaper technology, which significantly enhances display performance over previous generations. Hanvon Technology is set to debut the M10C II tablet utilizing the new display and its specialized timing controller.
Why it matters
The technology aims to reduce image graininess and improve color definition, marking a notable jump in e-reader visual quality. It addresses long-standing limitations in color gamut and contrast that have previously hindered ePaper for more dynamic, media-rich content.
Kaleido 4 supports 300 pixels per inch for color and video playback at 18 frames per second. The technology uses an oxide thin-film transistor backplane to support higher driving voltages and faster pixel refreshes.
The players
E Ink
This company is a leading manufacturer of electronic paper display technology used in numerous e-reader and tablet devices worldwide.
Hanvon Technology
This organization is a consumer electronics firm based in China that specializes in digital writing and reading devices.
The details
