I dont know if you've seen it, but lolje on UTI created color without frying your lcd or in any way damaging or frying it through the use of xLib.

Very nice indeed. I tried it out and you can change the effect of Blue by changing the waiting period between runs.

Yeah someone already made a Pong game in asm with that effect.

Well I never tried it on my SE, but on the 83+ it would look ok. Btw Michael of ticalc was the one who made it

wow I just tried it and its amazing, I think it would be cool for thunder animation in magics. I always noticed the screen flash when turning contrast down on the SE, but it is so fast that you dont even notice the blue effect, and it only happpens when the contrast goes from very dark to light

well I did notice that when you turn the calculators contrast way up it looks blue. where can I find a program that uses this blue line thing? and assuming that it is harmless is it possible to up the contrast on some pixels and not others?

DJ Omnimaga · « **Reply #6 on:** February 22, 2006, 10:12:00 am »

The blue line program is harmful but not the new blue screen one. I'll post the code later

Wow are you sure? I've heard that all blue screenness was bad especially on calculators as it damages the lcd. That would be nifty if there was a non-damaging way to do that.

DJ Omnimaga · « **Reply #8 on:** February 22, 2006, 10:32:00 am »

well that xlib one doesnt seems to make the Liquid crystal going out of the screen like the one at ticalc (which got deleted)

kalan_vod · « **Reply #9 on:** February 22, 2006, 02:47:00 pm »

With just changing contrast from the highest to the lowest (which this does) it will not damage the calc. But the other way is to overload the LCD (driver?) which can be harmfull.

elfprince13 · « **Reply #10 on:** February 22, 2006, 03:53:00 pm »

yeah...the usual way just sends to much power to the lcd. this way rapidly adjusts the contrast

crzyrbl · « **Reply #11 on:** February 22, 2006, 04:47:00 pm »

For the xLib blue method, would it be possible to make one area blue without changing the shade of the pixels around it? It would be cool to make an RPG char with blue eyes...

(btw, this gives a whole new meaning to "blue screen of death")

kalan_vod · « **Reply #12 on:** February 22, 2006, 05:22:00 pm »

No, single pixel rendering isn't possible with the calcs (unless diff. software/hardware was added).

Radical Pi · « **Reply #13 on:** February 23, 2006, 11:23:00 am »

...or you change the way TIOS percieves contrast...

Liazon · « **Reply #14 on:** February 23, 2006, 11:40:00 am »

it's probably more a hardware thing. Isn't LCD uniform contrast? in other words, the same electric current runs through all the pixels, and the only way to adjust contrast is by weakening/strengthing the current?
