Screen brightness-MFD vs Tablet

Hence its either dedicate ruggedised sunlight tablets etc or you buy a MFD.

personally for reliability , ease of use and outdoor suitability thd modern MFD can’t be beaten for value/performance

The market for ruggedized tablets is industry, not boating. It is huge and much of it is out of doors.

The problem is that the technology does not yet exist. Someday, perhaps soon, an e-ink (paperwhite) screen will be used on an android compatible device. They are not there yet.

Or another solution will be found.

Boaters can piggy back on the needs of field work.

High quality optically bonded transreflective lcd provides exceptional outdoor lcd readability , easily the the best

This could be seen in handheld plotters like the Garmin 276. Absolutely brilliant in sunlight.

E-ink will never cut it. Primarily because the nature means a slow display and hence not gif for colour or movement orientated displays.

Tablets are available ( I was a supplier of outdoor rugged computing ) with good sunlight screens and rugged usability. These have been available for years. But they can be 5x the cost of office ones.

This limits the market.

I’m not sure what you are arguing , rugged sunlight lcd can be purchased today , it’s just expensive that’s all.

Get a used one 2-5 years old.

Costs far less than new. Many of them where never used as hard as one should expect from their spec...

Navigation is not really an application requiring the latest processing power.

Thanks, but not helpful, and wrong.

Are you sure that the 1000 nits are correct? As a reference the B&G Zeus3 and Vulcan have 1200 nits (albeit I seem to remember that the Zeus is said to be brighter?).

Thanks, but not helpful, and wrong.

hu? why? Seems 100 % correct to me. E-Ink will never cut it (but could be an option if one is willing to accept the refreshing limitations). There is a Tripltek tablet with 1200 nits, no idea how good, but thus at least one tablet is available. I think you lost the way/arguments this time ...

What I meant is that my current tablet is spec'd at 1000Nits and it is unsatisfactory. I'm not sure if you are referencing Zeus3 and Vulcan MFD's or some tablet used with them via the Link app. If the B&G MFD's are 1200 Nit's that is good news for me because I know they are viewable and the tablet I've now purchased is 1200Nits as well, so that gives me some confidence,

E-Ink refresh rate on E-Readers is the main problem and lack of color saturation but we're not playing video games or watching Tik-Tok so black and white and mediocre refresh could be OK. However, the deal stopper is that the E-Readers do not provide the access to full android capability, (ie Google Play Store) and have not published, as far as I know, the API which would allow developers to develop their apps for the E-Readers. The apps I need cannot be run on E-Readers. (YET)

Thanks , but wrong and irrelevant

That guy makes those pithy one liners and clearly doesn’t understand the market. A few minutes with google will show you what’s available and the cost basis.

The industry typically sees 1000nits for outdoors , but systems are out there with upto 2500 nits for high intensity direct sun angle viewing . These are big power hogs and need serious heat handling systems.

Trans reflective lcd is probably better , but the huge TFT lcd production means large lcd outdoor has largely gone to high backlight tatics.

Trans reflective has remained popular for smart watches etc.

Unfortunately I agree again (with the wrong part).

Bye bye

fyi this could also be expressed with kthxbye. Or if it is really serious... KTHXBYE

Good night!

Well, I just bought it and it won't get to me for several days. I've been looking at what's available for a couple of weeks and holding off on the Tripltek but I finally decided there just are not many choices. Most of what people allude to just are not there, I mean a small, rugged, battery powered android tablet with Nits higher than 1000, or at least I never found them. Without a link or some sort of reference, it's just talk, not helpful.

As for the Tripltek, I'm looking forward to setting it up, got some networking to do and some apps to load. But it should be good, the specs are good.

And at least 10 more products , Android, portable 1000 nits or more

.

In your math you're forgetting the battery voltage. 15000mWh = 15000mAh only in a 1-Volt battery. In a 3-4V battery it is 4-5000mAh, which is in the realm of available, but still only gives you one hour of run time. But maybe that is enough for your use case?

Not a fan boy, but the iPhone 13 Max Pro is pretty much a small tablet, splash resistant if not waterproof (IP68 to 6 meters for 30 minutes), has a 1200nit maximum brightness in HDR mode (1000nit without HDR), and a 16.75Wh battery that will last several hours at that level. The hardware is out there. May not be your OS of choice, or large enough, or have the right apps available, but the hardware exists. Even pretty robust to drops, but if you want to improve that a case can be added.

The Samsung S22 Ultra carries similar specs, reports up to 1700 nits at maximum brightness, and carries the same IP68 rating to 1.5 meters (although they are very specific that that is tested in fresh water).

Yep, just as I thought, you're all talk but no facts. None of these ones you listed have screen brightness which you claim is so common.

ALGIZ RT8-Nits not stated

sihovision SC300A- Not a tablet, just a monitor, only 1000nits

Rugline mt1-Nits nor stated, and with 4400mAh battery it won't have much brightness for long

t71-1000nits, I have this one, it is unsatisfactory

Shandong Senter-scanned the first 10 or so, none NONE have stated NIT spec of ove 1000NITs and most either don't state it or are less

We're all still waiting for you to back up your claim that there are available 8" Adroid tables with screen brightness over 1000NITS (other than the one Tripltek I have known about for several days which I have since purchased.)

In my experience 1000Nits is unsatisfactory in bright sunlight, even with optically bonded screens.

Thank you, my math was wrong when I inserted AmpHours into the equation. But when the vendor says they need 1.25 amps at 12 volts, that's 15 watts, or 15000milliwatts regardless of the voltage. And the batteries in most android tablets are 10,000 mwh or less, as I read it.

As for the phones, the screen size and lack of "ruggedness" makes it unsuitable for my usage.

As I have been mentioning, I know the reason why tablets don't have the screen brightness of MFD's; it's that they don't have the power in a battery like the MFD has in the ship's power attachment. I should have never asked the question.

I did already know about an android 8" rugged tablet with 1200NITS and a 12000mwh battery, the Tripltek 8 pro, and I've purchased it. I was looking for options. I have not found any.
