I bought this
works perfect and is affordable. I would say it is just as readable as that playbook
In the first two shots of my last post, it appears as if mine works almost as well as yours when the sun/camera angles line up like they do in your shots.
When the screens are flooded with light they both perform well, but when the light is at an angle where it is reflected back into the camera or eyes it's impossible to see anything through the blinding reflection.
I think it's just a difference in installation.
In my car there is a ton of light and many opportunities for the light to reflect directly off the screen. You don't have an oversized sunroof to contend with.
Oh well, screens are a real problem with Car PCs. I spent hundreds of dollars already and have not found the perfect one. I dont care about resistive or capacitive, but even then its seemingly impossible to find a proper one. The one I use right now from a German manufacturer is extremely good at sunlight (even direct sunlight from above - convertible), but at night it is far, far too bright, even at lowest settings.
As if that wasnt a big enough problem, its also a PITA to find proper drivers or at least DTD values for those screens, if you use an Intel GPU and want to use the native resolution.
I always shed a tear when I see higher resolution screens in smartphones, where the whole smartphone is cheaper than the best Car PC screen you can get, while also having vast superior picture quality.
Right now I am even willing to pay up to $1500 for a 7" Car PC touchscreen that works good at direct sunlight, wont burn out your retina at night (and will adjust automatically to night and daylight of course) and has proper drivers.
I'm sorta with you. That screen's problem can be fixed though. You just need to create your own dimming circuit. Probably it only modifies the LCD's settings not the actual back light brightness.
I understand what you are saying about smartphones, but keep in mind 2 things. Smart phones are subsidized and are closer in price to $500 - $700+ without a subsidy from a phone company. Also, they sell millions of them so the price goes down per device manufactured.
I have no clue about electronics, so I dont know how to do that, and I also dont know if its even possible on my model. However, I am pretty sure the actual backlighting is dimmed on my screen. If I hold my hand over the sensor, it dims instanly and turns back to normal when taking it off again.
How can I find out if it would be possible to dim it more?
Just my thoughts.....
True, I always look at things like this as me doing it myself, since I'm good at it. Plus, any screen I buy I have to take apart down to the panel and embed in my dash anyway, so it really is a matter of to each their own.
To be honest though, I think the difference in quality would make it worth it. The playbook for instance is WAY more visible than the transflective screen. It just blows it away. You get what you pay for, and if you have to pay time vs money to get something that good, then so be it. If something is unavailable otherwise, it makes it invaluable.
Oh, if it has a sensor it likely is adjusting the actual backlight. Unfortunately it definitely sounds like that project would be over your head.
I absolutely agree that it doesn't make it less annoying... unfortunately there is the law of supply and demand. video games are not worth $60 but they can get it so they do.
I was into mp3car stuff a few years back and have an 8" transflective touchscreen that I paid $800 for, anyone interested in making an offer? Its daylight readable
