The Basics of LCD Panel

The basic concept of the workings of a basic liquid crystal "elements" or "sub-pixel":

• Elements of liquid crystal or LCD (liquid crystal display) is the material between liquid and solid, which are composed of molecules of the Crystal. Liquid crystal is then put in a container that has a surface of furrows like the image above.

• Liquid crystal having the nature of "where is the order of molecul-molecular alignment automatically follow the shape of the grooves their vessels"

• The upper plot different containers with under container flow, so that the arrangement of the liquid crystal molecules would like twisted.

• The top and bottom of the container mounted "polarizer" compiled with different direction 90 degree movies

• If a container of liquid crystal "got no voltage"-then the arrangement of crystals will be twisted like the picture below (left). And the rays "can break out" passing container

• If the voltage gets "Crystal"-then the molecules neatly arranged the crystals aligned vertically and rays "can not penetrate"

• Or simply put liquid crystal is said to be "can be arranged such as opening and closing the window" by giving the voltage on their vessels.

The Structure Of The LCD Panel

• The LCD Panel is composed of hundreds of thousands of sub-pixel like image below.

• To set the opening and closing of each sub pixel here there are thousands of very soft and transparent cables arranged vertically (up and down) and horizontal (left to.

• Connecting cable arrangement so often called matrix

• For example for glass panel with a resolution of 1280 x 800. There is a vertical cable connection as much as 1280 x 3 and hoisontal cable 800.

• Each sub-pixel given the color filter arranged like the picture below

THE ARRANGEMENT OF THE LCD PANEL.

The picture below shows the contents or order the complete LCD Panel.

• Backlight: the location there is the backmost. Generally use some sort of neon lights is called a CCFL is used to produce white light beam evenly on entire areas of the screen. It usually consists of several fruit CCFL lights are mounted horizontally and lined up for the new models has been changed using LED lights.

• Diffuser: a kind of filter that is used so that the rays of backlight exactly evenly on the entire surface of the field towards the future.

• Back Polariser: the rays are generated at random polarization has a backlight. Polariser is a type of filter that is used so that the rays of backlight single polarized vertically.

• LCD glass panel: this is the real part of the form image. Glass panels consists of hundreds of thousands of elements called LCD Sub pixels (picture elements). The number of sub pixel depending on the magnitude of the resolution and screen size. Each sub-pixel LCD controlled by a voltage so it can block the rays of light from the back or forward a ray of light froback. So the m the LCD is valid is similar to a kind of hundreds of thousands of small Windows, each of which can be opened-closed by a voltage matrix controller that can adjust the a little or much rays of backlight that will penetrate through it towards the front of the screen. Each sub-pixel is controlled by a transistor (TFT) that Act regulates the number of rays of backlight that will penetrate through each sub-pixel.

• Fiter RGB: RGB Filter pixels composed on the LCD so that similar kind of layers forming phospor as found in CRT television. His goal was to be able to produce color images.

• Front: polariser : is a filter type of Polariser Back, but has a horizontal polarization.
