TFT-LCD Display is developed as a further development is the active-matrix display the control of a matrix of thin-film transistors has been included. A liquid crystal display LCD or TFT-LCD Display is a screen whose function is direction of polarized light affect when a certain level of electrical voltage is applied.
How TFT-LCD Display Works
Just like LCD screen which consist of segments that can change independently their transparency controlled with electrical voltage in each segment of liquid crystals, TFT-LCD Display works in the same basic principle. A further development is active-matrix display which is employed in TFT-LCD Display.
TFT-LCD Display contains transistors manufactured from silicon which are formed to a crystalline silicon wafer like structures, they are processed from a mechanically thin film cut section of silicon deposited on any inert mold-able transparent layer like glass. The silicon layer for TFT-LCD is deposited using more complex methods. Transistors take up a small fraction of TCT-LCD display to allow light to pass through.
Material like Polycrystalline silicon is used in high quality TFT-LCD Displays.
Advantages and Disadvantages of TFT-LCD Display
TFT-LCD Displays lowers the power consumption, TFT-LCD Display has no radiation unlike Plasma Display. TFT-LCD provides a flicker, distortion-free images, which is ideal for sharp image resolution.
The liquid crystals inside the any variant of LCD display including TFT-LCD are toxic in nature and as the displays are usually used on movable electronic devices, they are liable to break. In that cases, the materials TFT-LCD leaks out and often the user never knows the leaked content of TFT-LCD can be poisonous as the manufactures usually never mention this point and keep the device with leaking materials from the TFT-LCD Displays which touches the sensitive part of the skin and the body might absorb the toxic materials. Users are advised not to use any electronic device with TFT-LCD Display which has a leaking screen, must pack it in a sealed bag and wash the skin to get rid of the toxic material if it comes in contact and consult an specialist Doctor at earliest if needed.
