Android Central Labs is a weekly column dedicated to deep dives, experiments, and a targeted look into the tech you utilize. It covers telephones, tablets, and all the things in between.
Likelihood is, you have used an Amazon Kindle earlier than. The primary time I set my eyes on that beautiful paper-like show instructed me it was the way forward for show know-how, however its apparent limitations meant that future was probably a long time away.
As we close to the twentieth anniversary of the primary Kindle, E Ink is better than ever. It not solely helps 1000’s of colours for a extra magazine-like expertise, however with refresh charges at round 40Hz, it is lastly ok for all types of content material, not simply books. Consequently, we have E Ink tablets, displays, and even smartphones that can do basically everything you need.
However one other show know-how could exchange it in most gadgets. It is referred to as Transflective Liquid-Crystal Show or Reflective Liquid-Crystal Show, typically abbreviated as RLCD. RLCD takes a “conventional” LCD subpixel construction and provides it the reflective properties of E Ink, making it seen in any sort of mild with out utilizing a backlight, all with as much as a 120Hz refresh charge. It seems like a win-win, however like something, it isn’t with out its faults. Let’s break them down.
Daylight, meet laptop
I have been utilizing a pill for the previous few weeks referred to as the Daylight Laptop. Whereas the pill is usually marketed towards the identical crowd that might be excited about a minimalist phone, I am most excited about it as a result of I can use it outdoor through the summer season with out squinting my eyes.
The pill itself would not look notably particular at first look, however its design is considerate and spectacular in a approach that does not shine on a spec checklist. It has sizable bezels, which is truly helpful on a pill, because it gives a handy space to carry.
The again of the Daylight Laptop is manufactured from a soft-touch materials, giving it grippiness that aluminum tablets do not have. Plus, it is received a pleasant contour that matches your hand, in contrast to the remainder of the overly skinny and flat tablets.

And whereas these design traits are fantastic, it is the show that basically shines for me, pun totally meant. Go outdoors, flip off the backlight, and benefit from the brightest, quickest show you have ever seen. It is 120Hz, so it is liquid easy, it doesn’t matter what you are doing. Extra importantly, the refresh charge ensures that it would not really feel gradual or sluggish, in contrast to even the quickest E Ink shows.
Daylight Laptop’s founders ensured that the bespoke show was 100% flicker-free. Whereas many shows declare to be flicker-free by way of TUV Rhineland certification, more often than not meaning there is not any perceivable flicker, not that the show is definitely flicker-free. Daylight Laptop is totally flicker-free, would not use colour dithering or FRC, and is totally eye-safe based on my own testing.
Its reflective nature additionally ensures that it really works completely in any sort of mild, and the twin colour backlight means it is snug to make use of even in dim mild. I notably love that there is not any perceivable ghosting, the best way many LCDs undergo from, and the backlight would not have that faint glow that the majority LCDs have, both.
It isn’t the primary RLCD machine by any means, but it surely’s the most effective examples of how good the know-how could be. After all, like several know-how, there are just a few downsides. First, Daylight Laptop’s RLCD is black & white solely. Whereas it would be honest to imagine this was performed for “minimalist functions,” it was truly resulting from reflectivity, in keeping with the corporate’s founder and CEO, Anjan Katta.
Katta instructed me that transflective LCDs change into considerably dimmer when colour is added to the combo as a result of approach pixel colour filters function. On account of testing, the corporate determined that daylight visibility was extra essential than colour. This review of the HannsNote 2, a colour RLCD pill, exhibits this off effectively. Verify the three:50 mark to see what I imply.
RLCD vs E Ink
So what’s higher, RLCD or E Ink? As with every show know-how, the reply relies on your wants. E Ink has been the go-to customary for a very long time for anybody involved with eye well being and the adverse results of backlights with PWM dimming, however RLCD can also be fully flicker-free.
The truth is, it is extra flicker-free than any present E Ink product as a result of the 120Hz refresh charge falls within the most secure vary, according to research. E Ink must refresh the show totally infrequently, and the comparatively gradual refresh charge (beneath 40Hz) has the potential to hassle folks prone to epilepsy.
E Ink additionally closely depends on utilizing particular display modes relative to the content material. Quicker refresh charges used for movies and web site scrolling cut back the general distinction and element to be able to make E Ink’s magnetic dots transfer sooner. RLCD makes use of a conventional show pixel construction, so the lights are both on or off and needn’t change modes for various content material.
The RLCD display on the Daylight Laptop produces extra element than any of the E Ink tablets I’ve due to its greater distinction picture, but it surely nonetheless one way or the other comes off trying “softer” than E Ink. Desire will dictate which look you favor, however there is not any denying the distinction in distinction the Daylight Laptop’s RLCD gives.
Moreover, colour RLCD has points with distinction on deep colours, primarily based on current colour RLCD tablets, whereas colour E Ink appears nice throughout the board.
Whites on E Ink additionally look loads higher as they’re truly white. The RLCD on the Daylight Laptop has a really heat, inexperienced tint to it, which does not hassle me, but it surely’s price noting as a quirk of the know-how. Viewing angles are additionally poorer than E Ink, however once more, I am undecided how a lot this impacts precise use of the product.
RLCD additionally requires fixed energy to show a picture, whereas E Ink magnetizes the picture as soon as, and it stays there till bodily modified once more. Consider E Ink a bit like an Etch a Sketch; as soon as the picture is there, it would not go away till you modify or erase it.
Which means RLCD tablets just like the Daylight Laptop can final days on a cost, however E Ink tablets could final weeks, even with common use. No matter this, RLCD’s 120Hz efficiency could also be well worth the tradeoff. It definitely is for me.
I’ve beforehand used an RLCD monitor, the EazeEye 1.0, and whereas that was illuminated from behind by pure mild to make sure it is brilliant sufficient for regular laptop use, I am assured {that a} bit extra time will produce one thing comparable in a pill that may eclipse colour E Ink for most individuals. The HannsNote 2 is a superb begin for colour RLCD tablets, and I hope to see extra colour RLCD tablets with nice frontlights sooner or later.
Prepare for a brand new sort of pill that challenges assumptions. The 120Hz RLCD display is ideal for outside computing, and the 100% blue light-free backlight ensures deep consolation even in dim lighting. Plus, a pleasant design makes it straightforward to carry and sketch with the included Wacom stylus.
