  LCD projector - Wikipedia, the free encyclopedia
LCD (liquid crystal display) projectors usually contain three separate LCD glass panels, one each for the red, green, and blue components of the video signal.
As light passes through the LCD panels, individual pixels can be opened to allow light to pass, or closed to block the light, as if each little pixel were fitted with a Venetian blind.
In 2004 and 2005, LCD front projection has been enjoying a come-back because of the addition of the dynamic iris which has improved contrast up to the levels of DLP.

 The Great Technology War: LCD vs. DLP
As light passes through the LCD panels, individual pixels ("picture elements") can be opened to allow light to pass or closed to block the light, as if each little pixel were fitted with a Venetian blind.
LCD projectors have historically had three weaknesses, all of which are more relevant to video than they are to data applications.
LCD has made significant improvements in visible pixelation and contrast, which were the two big deficiencies in LCD that caused many people to prefer DLP for video use.

LCDs can be added quite easily to an application and use as few as three digital output pins for control.
The LCD can be thought of as a "Teletype" display because in normal operation, after a character has been sent to the LCD, the internal "Cursor" is moved one character to the right.
For this instruction, bit 7 of the instruction byte is set with the remaining seven bits used as the address of the character on the LCD the cursor is to move to.

The LCD is made of two sheets of a flexible polarizing material with a layer of liquid crystal solution between the two.
The amount of transistors are defined by the LCD manufacturer, for example, the manufacturer may define 800 transistors along the x-axes and 600 transistors along the y-axes.
Because of this, an LCD screen which has a set resolution of 1024 x 768 can have a smaller display, however when the screen is decreased in size it will not use the complete screen causing the image to have a fl border around image.

There are lots of LCD types such as 1x8, 2x8, 1x16, 1x20, 2x20, 2x20, 2x10, 1x40 and there are also many different vendors.
Mostly an LCD has a 14 pin connection which are D0-D7 (Data Bits), E (Enable), R/W (Read/Write), RS (Register Select), Vee or Vo (Contrast), Vdd or Vcc (+5V supply), Vss (Ground/Earth connection) so there are 8 data, 3 power and 3 control lines for a standard non-backlight LCD.
If an LCD has a backlight it has additional two lines for that which are 15th (VB+) and 16th(VB- or Ground) lines.

 What is TFT LCD TV and LCD Monitor Panel?
Nearly all TFT LCDs are made from a-Si because of the technology's economy and maturity, but the electron mobility of a p-Si TFT is one or two orders of magnitude greater than that of an a-Si TFT.
The performance of the TFT LCD is related to the design parameters of the unit pixel, i.e., the channel width W and the channel length L of the TFT, the overlap between TFT electrodes, the sizes of the storage capacitor and pixel electrode, and the space between these elements.
In a TFT LCD's unit pixel, the liquid crystal layer on the ITO pixel electrode forms a capacitor whose counter electrode is the common electrode on the color-filter substrate.

LCD TV (or Liquid Crystal Display) works by trapping a liquid crystal solution between two sheets of polarized glass.
Within LCD televisions each crystal then either blocks or allows light to pass based on the broadcast information.
LCD technology allows screens to be thinner, and televisions to be lighter and more energetic than before, resulting in a flat panel TV that can fit in place where conventional televisions cannot.

The data lines on the LCD match up well with the data lines of the parallel port, and extra parallel port I/O lines can be used to simulate the RS, R/W, and E signals on the LCD.
The LCD module is pretty low-lower (with the exception of the backlight), so I found that it can be powered from most parallel ports.
The 10K pot controls the contrast of the LCD, though, in practice, I've found that it usually ends up at the ground rail, so you might be able to get by without the pot, and just tie VLC to ground.

 PC World - How It Works: LCD Monitors
The downside: The color quality of LCD displays typically can't compare with that of CRTs, and the high price tags of desktop LCDs mean they're still a luxury for most.
Electric leads around the edge of the LCD create an electric field that twists the crystal molecule, which lines the light up with the second polarizing filter and allows it to pass through.
But LCDs process information digitally, so when analog data from a standard graphics board reaches an LCD monitor, the monitor needs to convert it back to a digital form.
