trying to use my Samsung Galaxy Tab S9 Ultra ( i think that's the model ) in the car in Florida didn't work. too big, not bright enough during the day ( great at night ).
unfortunately there still doesn't seem to be any daylight worthy android tablet. the brightest ones are only about 30% brighter than my Samsung which is not worth upgrading for ( especially considering all other specs would be worse ).
this is pathetic because my ( now dead ) Sony Z9J TV was 3,500 nits and that was designed for use in the dark ... why can't they make an Android tablet with the same 3,500 nits for use in daylight ? why do the brightest tablets top out at 1,200 nits and that's for Windows tablets. Androids only go to 1,000.
because they're all fucking retards. battery life my ass. i have 92% battery life on my S9 Ultra after half a day of use - i don't need more battery life in my tablet - i need daylight visibility. i can't see shit on it while driving in Florida, meanwhile the car's screen is perfectly clear ( and about 4X brighter ).
why can't they just put the same screen they use in the car into the tablet ?
i think nostr:npub1rfw075gc6pc693w5v568xw4mnu7umlzpkfxmqye0cgxm7qw8tauqfck3t8 said he had some kind of daylight computer but it just seems to be e-paper like Kindle. e-paper is black and white and has slow refresh rate.
i just want an Android tablet but with about 4X the brightness of my Samsung and they don't exist.
the best solution i found so far is Android Auto ... but it would be nice to not have to use a single car screen for everything. would be nice to have a tablet that is equally bright.
oh well ...
It's not e-paper/e-ink or any marketing variation of that. The Daylight Computer has a custom 120hz transflective rLCD display that's perfectly legible in the sun without any backlight whatsoever. The more light, the better.
1600x1200, 120hz, 10.5", 190ppi
but it's black and white and has no backlight for use at night - correct ?
Yes, it's greyscale, no way around that. Perfect for reading though, not for comics or mangas and the like.
It has two backlights: One is amber and doesn't impact your circadian rhythm/sleepcycles, one is traditional LED backlight. Never used the latter, can't say much about it. But the amber one is very bright without burning out your eyes at night.
Only gripe: If you disable the backlight at night you need an external lightning source to illuminate the display sufficiently to pull own brightness controls to increase it.
cool device. last time i mis-understood your health claims regarding it. you said it helps with circadian rhythms because it doesn't emit blue light but you didn't mention that you were referring to amber backlight for night time use. it seemed you were talking about day-time use in which case the statement about no blue light made no sense since daylight is primarily blue light.
i am going to accept their claim that their amber backlight has less blue light than a regular color LCD screen with blue light dimmed in software, because LED backlighting is primarily blue and LCD panel has finite contrast so it can't block out the blue from the backlight completely, though probably with an OLED screen ( like in my Tab S9 Ultra ) with orange text on black background probably amount of blue light emitted will be negligible - less than what you would get from the moon at night ...
the main benefit of this daylight computer is probably for mental health due to being able to spend more time outside. and also from the extra vitamin D due to being in the sun, especially if you're in a northern climate where you guys don't get enough sun.
but it's not the type of device i want.
i want a regular android tablet but with 5 times the brightness versus what i have in S9 Ultra, which is already the brightest android tablet outside of rugged / industrial ones.
and i actually WANT a rugged / industrial one like Panasonic / Getac / Zebra etc. but those cost 2X versus Samsung and have much lower specs and are only slightly brighter ...
so i will continue suffering with my Samsung for the time being.
PS: thanks for clarifying what daylight computer is.

On thing though: The display ships with 2 different backlights, that are completely different hardware components built into the display and both can be turned on/off as you please. One is LED, one is amber. If you just use the amber one, there's 0% blue light. Don't have to filter out what you don't emit.
They even confirmed that in the lab.
yes i understood that.
but i think an OLED screen in dark mode would also be effective at cutting blue light, since OLED doesn't have a global backlight - each pixel has its own backlight and in dark mode 90% of pixels are simply turned off.
but if you have to use a global backlight it's nice to have an option to switch from a white to amber one.
anyway i have zero complaints about the OLED screen in my Tab S9 Ultra when using it at night. it is quite perfect for that.
and the other problem is that during the day i don't need my tablet to work in the park - i need it to work in the car - where it is somewhat shaded - but still too bright for my tablet - but may not be bright enough for your daylight computer.
so OLED is perfect at night. yours transflective display perfect in direct sunlight. but the situation in the car is in-between where you really want just a super bright LED display like the one the car has for infotainment system. i compared it side by side with the tablet it was about 4 times brighter. they don't seem to make tablets like that.
when i was driving i wanted to see what was around me in the area using google maps opened on the tablet while still keeping GPS navigation directions on the car screen ... but i was unable to do this because the tablet was too big, too heavy and too dim. best i could do was set up Android Auto on the car's screen and switch from perspective view for navigation to regular map view to check what's around me but that required switching back and forth between two modes ...
well this actually depends on the car. when i rented the new Mercedes E-Class i was able to see regular map view ( from Android Auto ) on the large center console screen and directions in the instrument cluster screen ... but i can't do that in my own car or in the cheaper cars that i have rented. also the Mercedes was the only one with a screen large enough to compare to a tablet - the cheaper cars i rented had a more phone-like screen.
the problem with that mercedes is when cornering you want to lean your knee on the door and the arm rest has a sharp edge that digs into the knee and is quite painful. typical mercedes retarded ergonomics.
so the situation is hopeless, but thanks for trying to help.
OLED in dark mode is quite decent, true. Now PWM either. Good on the eyes.
I bet the DC would work great for your scenario. Just set the brightness to 50% and you'll have perfect illumination in the dark/shades without being blinded by it and great legibility under the sunlight (where the amber backlight basically just wastes energy because you can barely see it).
If you're in the US you can buy it and send it back without costs, I think.
yes we have consumer protections in US so that we can return stuff to the store
on several occasions i would buy power tools from home depot, do some home remodeling and then return them - they always took them back without question even when they were obviously used
but i never returned anything i liked and had use for - i only returned stuff that i either didn't like or i knew i would never use again
so in practice it isn't a big problem. any business bankrupted by returns is a shitty business to begin with. i return stuff to Amazon all the time including expensive things like a TV ( because i didn't like the picture quality ) and Jeff Bezos is still one of the richest men on earth
i think this return stuff that seems to be unique to America is good - because it weeds out companies with poor products who get destroyed by returns. Chinese think if they sold you some trash they successfully tricked you - which is true if you bought from China - but if you bought from an American store in America you just return it.
Haha, I do the same. Started buying new games ewely 2000s, copied them and returned them and just kept following that pattern with various devices and tools, though with some limits and only when it didn't come with collateral damage to a small business.
Europe has good consumer protection laws in that respect as well.
i make no distinction between small and large business. in fact i generally avoid dealing with small businesses because they usually are a lot more greedy than large corporations. some pajeet in Amazon call center in India doesn't give a fuck if Amazon loses money when he grants me a refund, but a small business owner CARES A LOT if HE PERSONALLY loses that money. i find small businesses are a lot more reluctant to refund money than large corporations. only times i ever had issue getting refunded was with small businesses.
the purpose of business is to make money - this is the same for small and large business - only difference is to a large business you are a statistic and to a small business your refund is money the owner was personally planning to spend and therefore you aren't going to get the refund.
