    LCD PC Monitor Questions!

    Well after searching Ebay, I have become discouraged to buy a car based 21" inch TV for the rear seats (they go for about 500 - 1000 dollars). Instead I am going back to an older idea of simply buying a PC LCD display, which I can get for about 180.00 - 200.00 dollars. and creating a kit to hang it up.....

    I went to tigerdirect and lifted a few of the smaller ones and they are light as hell. The panels that are 17 and up are heavy. So I wanted to get some feed back on what I can do to lighten a display.... Is the technology similar to whats in a laptop? Is it possible to take out all the insides... example all the monitor connections for VGA and power and relocate them some place else, then have only the casing and panel on the roof? Also what would I have to do to power the thing? is it easier to buy and inverter or simply add it to my carpc power supply.....

    Any help would be appreciated!

    Everything is needed in an LCD and cannot be removed or even extended with some parts. LCDs dont use much power, even the big ones. You could run it off a 12v rail from a dc-dc psu. Choose one with a slim frame design, you know the ones with a 1/2inch border. Wide screen depends on mounting space and headroom I guess.

    Hi Hijack,

    My suggestion would be to look at some of the DIY LCD projectors. A lot of them are using larger, PC monitors stuck on an overhead projector. Their photos and worklogs should give you some clues about the monitor guts.

    I'd consider finding a monitor that uses an AC-DC power brick. A monitor like that would not have the AC-DC power conversion inside the monitor and would probably make the insides easier to deal with and the power supply easier to relocate.

    Also keep in mind that many of the desktop LCD monitors have rather sturdy metal framing inside, which makes them heavier. The LCD panel itself is probably significantly lighter than the whole monitor.

    Finally, most newer desktop LCD's use an LVDS interface. The cabling on LVDS can usually be longer than the older TTL signaling and requires fewer wires. If you get a monitor that uses an LVDS panel, you should be able to extend the wiring to the controller. In fact, you can even get a motherboard that has onboard LVDS, which may allow you to ditch the rest of the monitor's components entirely.

    HiJack,

    If you use a regular PC monitor, then you just need a VGA cable to connect to the LCD controller board that will be inside the monitor case.

    You would only need the LVDS connection if you plan on doing away with the control hardware inside the monitor. If that's the case, and the panel supports LVDS, then yes, the item you linked would work, provided the backlight inverter is separate from the VGA->LCD controller and still works.

    You should probably start doing some research on LCD panels, backlight inverters and signaling types if you plan on going down that road. You will probably get a much nicer, OEM look with very good image quality if you follow this path. Just remember that it's going to take a lot more research and work than simply mounting a monitor designed for desktop use and powering it with an AC-DC inverter.
