Pixel Qi, recently presented a working prototype of the display 3Qi, which certainly attracted the attention of the public. At SID exhibition Korean giant introduced 10.2-inch diagonal screen-based electronic paper capable to reproduce video. It sounds very unusual, but the screen is indeed a combination of LCD and E Ink (in 3Qi there was just 2 mode LCD).
Active matrix works with « cholesteric» (cholesteric liquid crystals), which can be switched between two states. In the «memory» pixels retain their state even without the constant feeding, and during a «dynamic» mode, they work as LCD panel and can display moving images.
«We are not interested to develop conventional displays based on electronic paper … this time we decided to do something that no one would do» – said the representative of Samsung Electronics.
The demonstrated prototype has a resolution of 320×240 and can display 64 colors with a response time less than 25 milliseconds. Judging by the reviews, the concept is still quite far from entering the market. There is still no information that the company plans to use this technology.
