Daylight_Co wow that's awesome! If this thing does not use FRC and is true 8 or true 6 bit color depth and not 6+2 FRC or 8-2frc, and does not use any form of dithering.. I will totally buy one

    I think this is some kind of scam.

    It seems to be just and LCD that is made to be black and white, but I don't see any reason why it would not have temporal dithering or other source of flickering as any other LCD.

    Why they just cannot make the displays they made some 7 years ago - those were perfectly strain free, just copy that techn and most of us would be done. No need for any fance e-ink or reflective LCD's. It's not about blue light at all, it's all about flickering due to various forms of dither and PWM.

      Agree 100%. The fact that a screen has no backlight does not exclude flicker; it is not even a 2 way dependance, like the backlight can be flicker-free, not tens of kilotertz mumbo-jumbo. Instead of going back to a solid-tested route, the producers like to scratch the left side of their head with the right hand, bringing up all kind of marketing gimmicks.

      One other main issues is that the marketers don't even understand the problem (therefore neither the fix) and they just relay on whatever the tech division tells them. They sell something that sounds cool.

        This looks way better than eink display. How many OS update does it get? Are you guys working on a color too?

        Maxx I totally agree with you on this. But maybe this have to do with fining manufacturer that can produce them.

        Do you know what are the technical specs that 7nuesrs old lcd design that make so eye friendly?

        Two things that I really like about eink display is no really bright light shining on your eyes and can view in a bright sunny day outside.

            Whether or not I win the raffle, I would love to try out one of your tablets using whatever mechanism is available i.e. tester, sale tryout period, etc.

              magi44ken I don't know for sure, but it seems that the color gimmicks, i.e. Temporal Dithering and of course PWM are the things that irritate the eyes.

              There seems to be zero effort on producing a flicker free display, but yet there are many who complain about dry eyes. We should get people to realize that it is not a problem of lubrication in the eyes, it is a problem of flickering light. It is also not a blue light problem. While there is some evidence that blue light in large quantities is not good for the eyes long term, it is not the source of acute eye strain. This can be easily tested by anyone, using a total blue blocker glasses or just very dark sunglasses. If it was blue light, then the glasses would solve our problem, but it does not.

              I'm afraid these companies are just out to prey on people like us, trying to capitalize on the blue light problem.

              But yeah, I'm open to trying this device, too, but seeing is believing.

                I would love one. If I won, I'd do an unboxing review on YouTube. It would be awesome to not have blue light in a device. My eyes are sensitive to led lights so it would be great.

                Daylight_Co So, our pixels do not emit light, which means there is no flicker

                No light emission does not mean no flicker.

                For example, I own a BOOX e-reader with Android that I run almost all of the time with the screen frontlight disabled, meaning it's purely naturally illuminated.

                Since the screen can only display literally black and white, meaning no shades of grayscale (unless it's set to the really slow HD mode, where it actually does display real gray), it uses dithering in order to display shades of gray.

                Thankfully, when it's still, it doesn't refresh with nothing happening (because e-ink doesn't need to)

                But whenever I'm scrolling, or something on the screen is animated, the dithering of these shades of gray then starts needing to recalculate itself every single frame. This causes really obvious flicker, twitching edges of text, etc. while the screen is in motion, even though there is no backlight.

                Thankfully, it's not that bad for me on the BOOX because this is only happening when the screen is moving anyway (because my problems are usually related to when this happens while the screen is supposed to be still)

                But if your screen is constantly running at 60fps, there can 100% be sources of possible flicker introduced at the pixel level that aren't related to having or not having a backlight.

                    DisplaysShouldNotBeTVs that's true with eink I can't use it due to how it dithers.

                    With you saying with no backlight involved and can still flicker, you mean dithering right or do you also mean inversion?

                      worth trying of course.

                      although even e-ink didn't work for me (actually e-ink is even worse than LCD for some weird reason).

                        jordan You're totally correct that e-ink dithers in various implementations of Fast / Super Refresh modes, but one place e-ink doesn't dither is in "HD mode". When you're using HD mode to force it to a super slow framerate, you can still get real shades of gray (with heavy banding) and a higher resolution.

                        However, in HD mode, you instead sometimes get those full screen flashes when refreshing or turning pages, which may bother some people (even though it doesn't bother me that much).

                        (In edge cases, you can also still get a glitchy "inverting from black to white effect" in HD mode that definitely looks flickery if you try to "force a smooth animation or scrolling to activate" instead of static page transitions)

                            jordan Hypothetically, 120hz e-ink would probably still need full refresh pretty frequently since ghosting would likely remain an issue

                            Also given that the only way we've managed to surpass slow Kindle-like refresh speeds so far is with fast modes that use dithering, dither-free fast modes in general still seems to be out of reach for the tech

                            Btw, since I mentioned Kindles, I think it would be helpful to document here that the reason why the Kindle Paperwhite causes strain is due to it constantly keeping the backlight on even at the very lowest level of the slider. The backlight actually cannot be disabled.

                            However, in comparison, the Kindle Oasis (whatever model was latest in early 2022) feels incredible to read — one reason is because the backlight actually can be turned off on this specific model, unlike the Paperwhite.

                            I also swear that the Oasis screen panel or anti reflective coating just feels much crisper and sharper to my eyes in general compared to the Paperwhite, even when backlight is enabled.
