Television Screen
Haven't you ever wondered about how your television screen works? The concept is really quite simply. Inside the screen there are thousands of tiny light bulbs most commonly Light Emitting Diodes. They are placed in sets of four including two green lights, one red light, and one blue light bulb. These light bulbs work together to form your screen. You may still be wondering how your screen manages to get all of these different colors. When your eyes see many colors that are not so easy to distinguish your eyes tend to combine the colors forming another different color. This concept operates much in the sense of blending paints together to form a different color, only your eyes are doing the blending not the paint in itself. With the use of computers each light bulb is individually turned on or off. With all of these light bulbs producing different colors they combine to form a picture as a whole, which is what you see. You may hear people talking about picture quality and pixelations and wonder how these relate. Pixelations are the representation of the amount of light bulbs and their size that are used in the screen. If you were to go up close to a jumbo tron you would notice the individual light bulbs and how each of them is a different color. Meanwhile if you look at an LCD television you would see no bulbs this is because they are too small to be seen with the naked eye. So how do Jumbo trons retain their brilliant picture quality with such terrible pixelations? Its all in the size of the Jumbo tron since they are made to be big and viewed from quite a distance away you don't see the tiny light bulbs because you are too far away to see. So jumbo trons are just a blown up version of your regular LCD television set.
