LCD, or the liquid crystal display, weren't "invented" for use in televisions. Televisions are just one application of liquid crystals.
The properties of liquid crystals were noted many years ago. When a voltage is applied to a liquid crystal molecule, it moves, or rotates. This property can be used to affect light transmission through a transparent medium.
A liquid crystal display is just an application of this phenomenon. The earliest application I know of was the production of low powered numerical displays used as an alternative to LED seven segment displays. Think of the handheld calculator. It typically uses an LCD.
The picture superiority of LCD televisions over CRT is debatable. I own a widescreen CRT television, and I am amazed at how superior it is to typical consumer level LCD or plasma displays in terms of colour accuracy, black levels and contrast. But it sure has its drawbacks: limited size, hernia producing weight and higher power consumption than LCD panels, for example. Plasma displays suck more power than either LCD or CRT, though.
I am sure that flat panel displays will one day offer something better, but they just aren't as mature a technology as CRTs yet. But unless you buy used, you are pretty well out of luck for buying a CRT display these days.
Also standard crt screens require a lot of power in their vertical and horizontal hold architecture. Using liquid crystal displays reduce the power used.
for convenience and luxury
first lets start where lcd's where invented: they where invented by Hans lcd who was king of timbuktoo and gave them to the rest of the world by military force
Sharp is the first compnay to use lcd in TVs
It was invented at Hull University
in the vagina age
Liquid Crystals were discovered almost a century ago, and first appeared in devices in the 60's. The first active-matrix lcd monitor was invented in 1972.
LCD TVs were initially meant for the portable market because they did not consume as much battery. The first commercially available LCD was made by Casio in 1983.
The active matrix LCD was invented by Westinghouse. Prior to that there had been numerous attempts to make a display using liquid crystals. None of these prior attempts produced anything usable.

Allen B. Dumont; 1972... i think
It was not Allen B. Dumont. George H. Heilmeier was credited with the invention of LCD. Allen B. Dumont developed an improved version of the cathode ray tube.
I don't know exactly who or when exactly they invented it. But I know that LCD screens have been around for quite a while. Remember all those little hand-held pocket TVs? they all have LCD screens, and they have been around for quite a while, way before regular home LCD TVs become popular with the advent of HDTV.
An LCD panel is actually a LCD screen that is part of your computer monitor or LCD Television. There are different types of screens such as plasma as well, but to answer your question, an LCD panel is the LCD screen on your monitor or television (provided it is an LCD model).
There are four major types:LCD (Invented in 1968)Plasma (Invented in 1964)LED (Invented in 1977)OLED (Invented in 2007)
The person that is credited with inventing the LCD monitor is George H. Heilmeier from RCA David Sarnoff Research Center. Heilmeier also worked with Lucian Barton and Louis Zanoni to create the first LCDs.

The LCD refers to integers. The LCD of 12 and 34 is 204
LCD refers to integers. The LCD of 15 and 23 is 345
The difference is in the backlight and resolution. LCD usually have better resolution.
