Liquid-crystal display
A liquid-crystal display (LCD) is a flat-panel display or other electronic visual display that uses the light-modulating properties of liquid crystals. Liquid crystals do not emit light directly.
LCDs are available to display arbitrary images (as in a general-purpose computer display) or fixed images with low information content, which can be displayed or hidden, such as preset words, digits, and 7-segment displays as in a digital clock. They use the same basic technology, except that arbitrary images are made up of a large number of small pixels, while other displays have larger elements.
3LCD
3LCD is the name and brand of a major LCD projection color image generation technology used in modern digital projectors. 3LCD technology was developed and refined by Japanese imaging company Epson in the 1980s and was first licensed for use in projectors in 1988. In January 1989, Epson launched its first 3LCD projector, the VPJ-700.
Although Epson still owns 3LCD technology, it is marketed by an affiliated organization simply named after the technology:"3LCD". The organization is a consortium of projector manufacturers that have licensed 3LCD technology to be used in their products. To date, about 40 different projector brands worldwide have adopted 3LCD technology.
According to electronics industry research company Pacific Media Associates, projectors using 3LCD technology comprised about 51% of the world's digital projector market in 2009.
3LCD technology gets its name from the three LCD panel chips used in its image generation engine.
How 3LCD technology works
Creating Colours from White Light:
A projector using 3LCD technology works by first splitting the white light from the lamp into its three primary colours of red, green and blue by passing the lamp light through special dichroic filter / reflector assemblies called “dichroic mirrors.” Each dichroic mirror only allows specific colored wavelengths of light to pass through while reflecting the rest away. In this way, the white light is split into its three primary color beams and each is directed toward, and subsequently through its own LCD panel.

Each Time
Please come back, I miss you, baby
C´mon, each time, ayeah
C´mon, each time, is the track blowin´ my mind, ayeah
Have you heard of a sayin´
For those who are playin´
You don´t know what you´ve got ´till it´s gone
Well, there was my calling
I knew I was falling
Into something that would be so wrong
But I caught hold of myself
And change for the better
I can´t get you out of my mind
´Cos something inside
Made me realize you were fine
Each time when we´re alone
I guess I didn´t know
How far we were appart
Should´ve spoken to my heart
I guess I didn´t know
That each time you´d go away I´d cry
I can´t take all these good-byes
I know from this feelin´
Deep inside there´s a heelin´
I know that I´m in controll
Every day I am yearnin´
This love I feel burnin´
Burnin´ right through my soul
So let´s make the start
Of somethin´ that cannot be broken
The mould is so strong
Treat this love as a child
That grows into somethin´ worthwhile, ohh
Deep, love so deep
Deep, love so deep, yeah
I can´t take all these good-byes
Faithfully, I will be
You will see, please believe me
I can´t take all these good-byes
All the time we were alone
Guess I should´ve really known
