[OTZ80] [Poll] What do you want the screen resolution to be?
« on: August 25, 2010, 01:46:58 am »
As the title says: What do you want the screen resolution to be?

Consider the CPU speed, the cost of the screen, and the use of the resolution.
Especially consider the cost - you don't want the screen costing a half or a third of the total cost!

Note that the screen will be grayscale, and that the size should be similar (maybe 1/4-1/2 cm off) to the TI-83/84 screen size.

I put 240x160.  Not huge, but its a very reasonable resolution for a calculator.  Also cuts cost

1920x1080.

just kidding :P

I think for the OTZ80 calc, 240x160 seems fine. Not too big and not too small.

240x160 seems fine great to me!

if it get's too expensive (which I am not sure about) then we might go one step lower but I think we Definetely want more then good ol' 96x64

I voted 192x128-it'll be good enough for a calc, cost less than the others, and make our lives easier when writing a compatibility layer for 8x programs. (multiple of 96x64)
Also, I think the screens themselves aren't grayscale, just the lcd driver does the same thing we do with calc grayscale, though a lot more efficiently.

Why not have hardware greyscale? Basically, it is the same thing we do with software grey, but the LCD Hardware Controller outputs lower and higher voltages, using Pulse Width Modulation (basically, the only way for digital stuff to do analog output) and that is exactly what we do with software Grey, except that the controller can do it much faster. Combining hardware and software can get you around 64-level greyscale with a fast calc.

Agreed :) And it's tied.

I voted for 240X160, although the next size down wouldn't be too bad either.

I dont know very much about screens, but this comment does it for me. I know how hard compatibility can be for some hardware.

Yeah we need a LCD driver that either has native grayscale (4 levels?) or supports good looking grayscale. Something like the original TI-89 HW1. By HW2, grayscale started to look a bit less good.

So, in the end, no one voted for 96x64 :D

Guess it really does suck...

Yeah it does. Few lines of text at once, unless you use small fonts, which are harder to read x.x

Right, so will this still use 5x7?

Idk. I guess anything that is easy to read on small screen but won't take too much space on the screen.
