- Spectra 6 uses E Ink's ACeP technology with microcups containing red, blue, yellow, and white ink particles to generate six standard colors.
- ChLCD e-paper has three layers reflecting red, green, and blue, capable of reproducing over 16 million colors with bistable liquid crystal states.
- Spectra 6 shows high saturation in yellow but lacks in green, magenta, and cyan, while ChLCD offers a more comprehensive color performance.
- In gradient tests, Spectra 6 displays cyan as light blue and magenta as purple, whereas ChLCD provides more accurate color gradients.
- Human portraits on Spectra 6 have sharp shadow edges, while ChLCD delivers smoother transitions and finer details in skin and hair.
- ChLCD outperforms Spectra 6 in food images with more vibrant colors and clearer details, such as in dragon fruit and kiwi representations.
- For fashion advertising, ChLCD's magenta performance is closer to the original image compared to Spectra 6's grayish tones.
- ChLCD is suitable for outdoor applications with an operating temperature range of -20°C to 70°C and resistance to harsh weather conditions.
- Spectra 6 takes around 15 seconds to refresh an image, while ChLCD updates a full-color image in 1-2 seconds.
- ChLCD, using traditional LCD manufacturing processes, is promising for large-size displays, potentially reaching 100-inch screens.
