LCD (liquid crystal display) screens
LCD screens will be the present standard of the screen for TV screens, many PC screens and electronic devices including mobile phones, digital cameras, and MP3 players. Two polarizing filters are typically contained by LCD PC monitors with liquid crystal filled pixels or cells. The light which passes through the primary filter is created by a backlight, while electrodes regulate a current which passes throughout the liquid crystals and discovers their alignment. The electrodes modulate the alignment of the crystals, creating intensity as well as the light color of the picture.
OLED (organic light emitting diode) is an emerging display technology that is yet to make it to the PC monitor mainstream due primarily to high prices now related to HD monitors for gaming screen production. OLED displays take advantage of the rule of electroluminescence; using substances which glow when a current is used, as opposed to relying on a backlight. What this means is the computer screens have an unmatched color reproduction, contrast ratio and response time are a lot narrower and lighter and may be made flexible. Although this technology is not presently used on PC screens, smaller displays such as those on high-end touch screen telephones, digital cameras and the incredible 11-inch Sony XEL-1 TV (featured in the video below) attribute OLED technology.
An alternate technology is the utilization of highly efficient ‘white’ LEDs across the border of the display (typically called ‘edge-lit’). An actual benefit of edge-lit LED technology in HD monitors for gaming -the-display backlighting is you could make displays which can be lighter and significantly thinner. Even though the real color gamut isn’t typically expanded beyond that of standard CCFL lamps the purity of light and responsiveness may also supply a contrast and perceived luminance edge over CCFL backlighting. Without a suitably high color depth.
