LCD panels

[zardoz]

Keep in m ind the specs on the 462....they only list it as being tested on some prety big panels. 17 thru 20 inch models....if it will support smaller panels it is a great piece of gear... if not I think the cost of the LCD screen up at these sizes would scare a guy silly!

If you want to use a LCD monitor as the basis of your PJ I'd look a the viewsonic device.

Oh ****!

I just found a 1600x1200 15" display /w an inverter for $525. Now I know that's out of many people's price ranges (as well as mine) so you probably don't care. But for just that much you can make the best projector on the planet.

IBM Dell Inspiron 8000 C800 15" UXGA LCD w/inverter $525.00

Now what would the inverter's output be? Since the LCD is from a laptop.

Screw $525. There have been a bunch sold on eBay from $170-$225 for just the panel. Hope somebody puts up more. I wonder if the AVR-462 will work with it. Or what will up to 1600x1200?

if you plan of removing the backlight from the LCD the inverter is useless. It only fires the CCFL backlight tube...kinda like a mini flourescent tube and ballast setup. I agree it would make an awesome PJ !

Shadow... you are going to have to try to find out what model of panel is in a Dell inspiron( or whichever you choose). Here's where we run into trouble.....take for instance Toshiba laptops...lets say we have model X... the toshiba model X can have many differant screens fitted to it, this was made clear to me by a very helpfull guy that does laptop repair near me...he showed me one model of toshiba that has 18 different screens that will run on it....allthough they are all listed as from model X only the one matched to the controller in the laptop will work. (according to him) Further experimentation might prove otherwise, but he doesnt care... it's customer money so he just orders THE screen that is being replaced.

I will have my S270M card next week and have a sharp screen coming from the US next week also. The thing is mine are matched and known to work, but I have suspicion that if pinouts are the same from a ...oh .. say 12 inch LVDS sharp to a 15 inch LVDS sharp I think the 15 might also work. It's my theory that Spectra couldnt possibly test all the panel variants, so they only post the KNOWN to work with list

I emailed Spectra and asked if the Sharp LQ150U1LH22 (the model for the 15" UXGA screen) will work on any of their 1600x1200 controllers. I also emailed another company if they knew of a controller for the LQ150U1LH22. If a 1600x1200 one does exist, I'm going to get the screen and controller in a heartbeat.

I hope that certain other folks that are in this forum learn from the likes of you and I, too many just sit back and look for reasons/excuses not to comit to anything. And as such do nothing to further the effort... and in some cases setting us back a fair bit.

In any event it is never a total loss a failed attempt is just one more "could be" that we can rule out......for now at least

Code breaking

I was very interested in shadowfax's LQ150U1H22 lcd panel so looked it up on Google and got no documents.

Anyway how do they code these panels

Here is a partial breakdown of Sharps panel code

LQ..........150............U.........1............ L.........H...........22
LCD......15.0 inch....UXGA

The 1 after the U is likely to be year of manufacture = 2001

Rest of code = unknown

Examples

LQ133F......... = 13.3 inch SXGA
LQ141F......... = 14.1 inch SXGA
LQ150F......... = 15.0 inch SXGA
LQ150U......... = 15.0 inch UXGA
LQ196U......... = 19.6 inch UXGA

My last tracking on my parcels shows my US money order for my panel was recieved yesterday. Does the US post deliver on Saturday? (that's prety cool if they do... talk about service!)

My controller is in Montreal awaiting fedex broker/customs clearance ... seems they dont work on the weekend.

Still in debate on the lamp mount in my reflector of the moment. I think I'm going to mount the lamp on a board and just do some position tests by moving the reflector around the lamp.

It's gonna get REALLY BRIGHT !!! in my living room tonight

Dell Inspiron UXGA displays normally have a 250:1 contrast ration, however the new "Ultrasharp" UXGA displays have a 400:1 contrast ratio as well as a better response time. Someone should find out which model is the "Ultrasharp" one is and which ones are not.
