More Information About Flat Screen Display Systems
Some of the most exciting developments that have taken place within the audiovisual market in recent years have, without doubt, centred around flat screen display technology. The choices available for both commercial and domestic applications are diverse and offer outstanding viewing quality.
From transmissive LCD (Liquid Crystal Display) monitors to emissive displays that include LED (Light Emitting Diode), OLED (Organic Light Emitting Diode), Plasma Display Panels (PDP) and a wide range of matrix displays that incorporate active and passive display technologies, Asysco's product range offers a realm of stunning visual solutions.
The technology behind flat screen display products continues to develop apace and this is a guide to the science behind today's most exciting display equipment.
LCD monitors comprise two polarised, transparent panels with liquid crystals and a matrix of electrodes held in between. When light shines from behind the panels, each crystal will either allow it to pass through or block it. Transistors allow red, green or blue light to pass through the liquid crystals which forms a colour picture. Colour saturation and intensity is determined by the speed with which the light is allowed to pass through the LCD.
LED displays incorporate light emitting diodes. The LED acts as a semi-conductor in the same way as a transistor and when voltage is passed through it, light is emitted. Red, green and blue LEDs together form a "pixel module" and large numbers of modules are arranged to form the viewing surface.
OLED displays function in a similar way to LEDs and LCDs, but comprise an emissive electroluminescent layer that contains a polymer substance which enables a film of organic compounds to be deposited in rows and columns to form a matrix of pixels.
Plasma displays comprise thousands of tiny pixels with their own sub-pixels of red, green and blue and filled with a mixture of neon and xenon gas. When a pixel is "energised", the inert gas ionizes, takes on a plasma states and gives off ultra-violet rays that strike phosphorescent chemicals and produce light.
