The RGB code is a system of three (3) primary color-coded bands that represent the colors of red, blue, and green. The RGB code is useful in a number of situations, ranging from computer screens to television sets to the backlight on digital cameras. The RGB code also makes up the contrast ratio used by LCD monitors.

The RGB code was first developed by a German electronics company called RAL (Radio Corporation of Germany). The original code was designed for use with the Nuvoton laser printer, which was a German company. Since then the code has been developed further and adapted for other uses. Today the RGB code can be used for all kinds of devices.

The most commonly used RGB code is the traditional RGB code, which is still widely used in printers. Other uses for the RGB code include computer monitors, projectors, DVD players, video game consoles, DVD drives, CD burners, TV monitors, VCRs, DVD players, DVRs, CRT monitors, and DVD players. In the past decade, however, the RGB code has been superseded by the dot matrix method. The dot matrix method uses black and white stripes that create a much more uniform appearance.

There are two different types of color TVs: LG, Samsung, Panasonic, Sony Ericsson, Vizio, Samsung LCD, Samsung Plasma and Sony CRT. All have different color channels, which correspond to different color ranges.

Most television sets now have a display option called True Color (or Full spectrum), which is a combination of the standard RGB and the DVI (Digital Video Interface). This option automatically converts the standard CRT scanlines into the correct range of color, which helps produce a more accurate color display. Another option is the Automatic Brightness Control feature, which automatically adjusts the television's brightness according to ambient light. The last option is the Automatic Color Temperature control feature, which allows the television's internal colorimeter to automatically adjust the temperature of the plasma screen according to the user's preferred setting.

The reason why the RGB code is useful is that it is not dependent on the color filter being used. For example, if a CRT monitor was to be replaced with a plasma monitor, the new monitor would display a color that is dependent on the pixels that make up the CRT pixel. Instead of displaying the color that is based on the pixel, the new monitor will display a different color based on the phosphor layer that makes up the CRT layer.
