Today, many choose to buy an LCD TV - Optics and weight play a major role. Furthermore, these TVs also contribute to a better viewing experience. LCD stands for Liquid Crystal Display (liquid crystal display). These TV images are created by using liquid crystals.
How LCD TVs work
The liquid crystals are located between two panels, power changed the characteristics of individual particles. The amount of light transmitted depends on the particle state and varies from opaque to display a black screen up to full amount of light to display a white image.
Do not produce the liquid crystal light itself, but the fluorescent backlight. The backlight produces a scattered light which provides uniform illumination of the screen.
The different light intensities by a change of Tension of each liquid crystal produced. To control this voltage, two methods are used - passive matrix and active matrix structure structure. LCD TVs use the active matrix structure. In this way, individual pixel electrodes on acting, which enables more precise, more accurate images. More detailed and more colorful images are created.
Each pixel consists of other subpixels that represent the colors red, green and blue. Certain colors, up to a certain extent be filtered out, with the combination of red, green and blue, the representation of each color succeed.
Why an LCD TV benefits
These TVs are suitable for watching HDTV content, but also for playing video games. Moreover, these TVs via composite video port and Scart connection.
Another advantage of LCD TVs is the most energy-efficient fluorescent backlight, so these TVs are among the current savers. Besides these advantages, LCD TVs also offer the following advantages:
space savings - LCD TVs are in all Sizes, ranging from 15 inches to 45 inches. Compared to conventional tube TVs they need despite the big screen - but thanks to the flat design - less space. Even more space you save when wall mounting.
video and audio of the highest quality - These TVs are known for their high quality display of video material, which contributes to improve the viewing experience. If you compare an LCD TV with an older standard TV, the differences are clearly visible - but especially for larger Screens, in which errors particularly noticeable.
LCD TVs have many great extras, it is still important in the purchase, to deal with factors such as contrast ratio, color and brightness. These televisions can display, usually more than 16 million colors. Brightness is measured in ANSI lumens and here, the higher the measured lumen rating, the better the image quality. Considering these factors, we find a high-quality low-cost LCD TV determined.
