I need help creating a thesis and an outline on How Does LCD TV Work. Prepare this assignment according to the guidelines found in the APA Style Guide. An abstract is required. The liquid crystals are split into small parts which are known as pixels. pixels can be considered as the smallest unit of screen resolution. Kondolojy states in one of his articles that these pixels have the same features as the liquid crystals. They have an alternating behavior in allowing the light to pass through them. The crystal molecules are activated or deactivated on the screen&nbsp.on the basis of the image that is to be generated. LCD TV Reviews UK (2009) explains that the front screen which is made of glass is imprinted with a grid. This facilitates the alternating behavior of the crystal molecules between activation and deactivation.

Producing Picture

Crystal molecules do not emit light, therefore, a system has to be put in to do the job. A backlight system provides the necessary light to the molecules which are required to produce a picture on the screen. LCD TV Reviews UK (2009) explains that there are three backlight systems that are commonly used in LCD TVs. EL system (Electro Luminescent), CCFL system (Cold Cathode Fluorescent Lamp) and LED system (Light Emitting Diode).

TopBits.com describes the process and states that when a picture is required to be displayed on the screen of the LCD TV, an electric current is allowed to be passed through the crystal molecules. The amount of electric current corresponds to the intensity of the colors required for each pixel. A unique feature of the crystal molecules is that they act as shutters and allow only a specific amount of light to pass through them. If there is a requirement of a dark picture on the screen then the molecules will prevent light from going out of them. In the same way, the lighter picture will make the molecules emit the corresponding amount of light. Tyson states that due to the variation in the emitting of the light, the output on the screen will be exactly similar to the input video signal. Colour is added to the picture by a special filter layer that is placed behind the crystal layer. In LCD TV technology, one pixel contains three pixels. These three pixels are of primary colors. red, blue and green. Kondolojy explains the process of coloring the picture in LCD TV and states that due to the variation of the electric current applied to the pixels. every pixel is able to generate over 256 shades.
