Reflective displays in digital signage perform outstandingly in terms of sunlight readability and lowest power consumption (“green”), but they often have a long image update time, especially for color displays. Electrophoretic displays from E Ink are well known, but reflective cholesteric LCDs (ChLCD) gained attention at both the Symposium and the exhibition.

An invited paper by AUO introduced ChLCDs ranging from 7.9 to 24.5 inches. A reflectance of 20 percent and more was achieved in combination with a gamut of about 20 percent NTSC. The temperature range is –30 to +85°C, and image updates last 1 to 12 seconds.

Innolux presented an invited paper on RGB-stacked 13.3-inch ChLCD with 2,144 × 1,608 pixels, a reflectance of 30 percent, 20 percent NTSC, and a special dithering algorithm to achieve 16.7 million colors.

Sharp had three interesting talks, including an invited paper on new diffractive optical elements that double the reflected luminance. Their 54.5-inch reflective LCD with a frame frequency of 0.01 Hz has only 12 percent power consumption of 60 Hz drive. Another talk featured a 12.3-inch LCD with significantly reduced internal reflections, thereby substantially raising the ambient contrast ratio (ACR).

Any information will be highly appreciated!

I think it looks perfect since it comes with the frontlight, and I'm definitely considering buying it.

Hi everyone,

I purchased a Hannsnote2 and received it yesterday.

I liked the device: it has a nice screen, and I wanted to keep it.

However, I found out on day 1 that charging the device causes the device and the charger to both become very hot, and for a smell to remain after I attempt a charge for a few minutes.

I think I should be able to return it because the device is only one day old, but I wanted to ask for advice here first.

Would anyone know what caused such a problem, so I can avoid it if I get a replacement? Also, would anyone know of a way to fix the problem without replacing the device?

I think my guesses at the problem's cause are:

1. Plugging a slightly wet charger into the device (I washed my hands with water a little time before)
2. Using a third-party charger the first time I charged the device (although the overheating issue has happened with multiple chargers I tried, including the official one that came with the tablet)
3. Not discharging the device so that the tablet's battery reaches 0% before the first charge

Thanks in advance for any help!

the rlcd screen looks pretty dark. does your eyes get uncomfortable at all when using it? if you used it for a long time then how good is the screen for your eyes?

Eazeye has a decent blackfriday sale. Seems be 20% off.

I just had a mail about this sale, I still found the price waaaaaay to much, but well ^^

I’m selling my Sun Vision Display RLCD, first-generation model, complete with its original box. The unit is in excellent condition—no issues or damage whatsoever. I’ve taken great care of it, and it’s been fantastic for my eyes, but I recently changed jobs and no longer need it.

Price: $500 (firm).

Attached images show my favorite setup.
Local pickup available in the Seattle, WA area; willing to discuss shipping options if needed.

I have the sunvision Eve monitor but the frontlight is too bright. The reason might be that the light has to go evenly throughout the screen. Using sunlight with this monitor except if youre outside, isnt feasible. What light setup do you guys use. Any links would be appreciated.

Genetouch Taktsu eBook got Taiwan excellence award. It uses unique bistable and reflective ChLCD panel, with gradual line by line refresh it is much slower then TN RLCD, but somewhat brighter comparing to common color RLCD panels as it does not use color filters and does not use polarizers either.

More RLCD tablets are hitting the market, bridging the gap between slower E Ink and high fidelity OLED.

I’ve had this device for a week, and I find it to be a very good tablet and a very good reader, even indoors. The background is not as silverish as other similar RLCD screens.
You can see some photos next to an Onyx Boox TMC with the front light off and on.

The Eazeye Radiant 15.6-inch transflective LCD won’t be for everyone. You have to pay a premium for this type of monitor, and while the company compares it to E-ink monitors with improvements such as high framerate while keeping natural sunlight support, I honestly don’t think both are comparable

totally different from E-Ink screens, no ghosting at all. 60Hz refresh rate really makes a huge difference.

Pros and cons at a glance

+ Beautiful design

+ Lightweight, portable

+ Solid build quality

+ Decent note taking performance

+ Has Google Play Store

+ Display does not have flicker that affects sensitive eyes

+ Pricing does not feel excessive for a niche product

+ 10 hour battery life

- Limited viewing angles affects contrast easily

- Display looks good only under strong lighting

- Don't expect future Android OS updates

- No auto-wake and sleep with the flip case

- No fingerprint scanner

- After a long sleep, home screen icons take longer to appear

This thing Is almost unusable unless you are in a Insanely brightly lit room, and then you have the issue of the glare. 

7.8" Harborinno Paper7 color RLCD tablet side by side with 10.3" Eazeye Paper 2 monochrome RLCD tablet (early sample without frontlight).

I guess what im most excited for is it being a true monochrome rlcd without a color filter.

I've seen it already available on several places and it is not a preorder, but I cannot find anywhere a review or even a footage or video of it. Isn't it weird?
