How to Work in Producing Color LCD Monitor
The Simple LCD (Liquid Crystal Display) consists of two main parts. the backlight and liquid crystals. Backlight LCD itself is the source of light which usually consists of 1 to 4 pieces (such tech) fluorescent lamps. Backlight lamp is white. So how LCD can display more colors? Here, the role of liquid crystals. Liquid Crystals will screen backlight. White light is the order of several hundred light with different colors (if you still remember the lesson of Physics). Several hundred light will be visible if the white light reflection or a change in direction experience beam. Colors that will be generated depending on the angle of reflection. So if different angle of reflection will also vary the resulting color. By providing electrical voltage to a certain value. Liquid crystal can change the angle. And because the liquid crystal duty is to reflect light from the backlight, the previously white backlight can be turned into many colors. Liquid crystal works like a window curtain. If you want a white color liquid crystal displays will be open as wide so that a white backlight that will appear on the screen. But If you want to display the color black. Liquid crystal-meeting will close tightly so that no backlight is that through (so the screen will appear black.) If you want to show the other colors live set the angle of reflection liquid crystal.
Good for laptop or desktop screen, an LCD display consists of many layers, the term is a "sandwich". A fluorescent light source, or backlight, is the bottom layer. This light will pass through the filter of the first two filters (polarizing). Rays that have been polarized and then passed through a layer that contains thousands of spots aligned liquid crystals in a small container called a cell. Each cell, also lined up forming a line on the screen, one or more cells will form a single pixel (the smallest dot size on a screen). Electrical source around the LCD forming an electric field that will thrill crystal molecules, which will regulate the light that will pass on the second layer form a polarized filter and pass it. On a monochrome LCD screen, like on a PalmPilot or a digital watch, so how it works: Closing open, and the work is completed. But on the color LCD, like on a PC laptop, they work more complex.
In a color LCD panel, each pixel consists of three liquid crystal cell. Every third cell has a red filter, green, or blue (red-green-blue/RGB). Light passing through the filtered cells will create the colors you see on the LCD. Sometimes the system that sends an electric current in one cell or more is not going well; incident gave rise to a dark pixel and "broken".
Almost all modern color LCD screen-as-a laptop or desktop monitor using a thin film transistor (thin-film transistor / TFT), known as active matrix, to turn every cell. TFT LCD creates a clearer image, clear and bright. Previous LCD technology is very slow, less efficient, and the contrast is very low. Previous matrix technology, passive-matrix, capable of displaying clear text but leave a shadow when the display changes in quick time, so not optimal for video. Currently, most of the black-white palmtops, pagers, and cell phone use passive-matrix LCDs.
Contrast Ratio Contrast ratio is the ratio of the lightness (brightness) at the position of most whites and most black. At the time of liquid crystal-tightly closed meeting to produce a black color should be no backlight light through it. But in reality there is still a light that can penetrate the backlight of liquid crystal so it can not display black properly. This is one of the LCD shortage. So the greater the contrast ratio the better it will display the color LCD. the easiest way to
find out how good Contrast Ratio LCD is to display the black color on the screen. If the black color tends to gray then there are few who managed to penetrate the backlight of liquid crystal.
Time Response of liquid crystals in the LCD works by opening and closing like curtains. Open and close the process takes place very rapidly (follow the movement of images on the screen). That is why there is the term Response Time on LCD. Response time is the time it takes to change from liquid crystal sealed position (when displaying black color) to a liquid crystal wide-open position (when displaying white color). So the faster the response time the better. Response Time, which later would cause picture defects called ghosting or image trail. Normally on fast-moving objects and generate trace images like some squares that look like a square.
Point of View (Viewing Angle) LCD Monitor has a limited perspective when compared to CRT monitors. Image objects on a CRT monitor can be seen clearly from the point of 180 degrees though. But not with the LCD monitor. If we look a little shifted from the LCD then the image of the object will appear darker or lighter. If the view from 25 degrees above the line it will show the maximum contrast and best display. If the view from 30 degrees above the line will appear to the reduction of contrast, the more upward contrast eat les
