Hi buts101,
You can using RF modules. These modules operate on 433.92, 418 or 315 Mhz., same as the standard TLP & RLP 434 modules but they have made significant changes in the size of the unit. They are SAW based and offer about 100 meters range in Line-of-Sight operating form 2-12 volts. The new version has a data rate of 4.8KB/s, over double the speed of the previous version and still provides 16DBm of output power off under 20mA of current. The module uses ASK as the form of modulation and has both digital and analogue outputs.
The size and simplicity of these units make them a professional and economical solution for many wireless applications. Is full compatible with the older version of the RLP433 for the advantage of people with existing units however we would recommend their use with the New RLP433(A) Module as they will provide better stability due to the inbuilt SAW resonator as opposed to an LC type.

Hi
From my viewpoint it depends on the LCD characteristics. Some questions you may think about are, is the LCD a comercial one or are building it? is it connected to a pc or pc like device? is it going to work indoors and can be connected to a wired network?
According to your answer there are many solutions, the easiest is of course that you LCD can support conexion a LAN, then you can use a wireless server for 802.11a/b/g. If your LCD woks connected to a PC, you can employ 802.11a/b/g or bluetooth (considerations such as distance and data rate will determine which one you use) between the local and remote computers, for example look at this link for and example http://www.pc-counselor.com/ad-hoc.htm. The advantages of employing this standards is that most ot them are already embedded on the modern laptops (you need to confirm according to your applications). If you want to build your own one you need further information.
good luck
Sal
