What is an LCD and how does it work


LCD stands for “Liquid Crystal Display” and it is a type of flat panel display that is commonly used in electronic devices such as smartphones, televisions, and computer monitors. LCDs are preferred over traditional cathode ray tube (CRT) displays because they are thinner, lighter, and consume less power.

The LCD works by using liquid crystals that are sandwiched between two polarizing filters. When an electric current is applied to the liquid crystals, they align themselves in a particular way that allows light to pass through them. The alignment of the liquid crystals determines whether the light passes through the polarizing filters and is visible on the screen or is blocked and is not visible.

LCDs use a backlight to illuminate the screen, which can be either fluorescent or LED. The backlight is placed behind the polarizing filters and shines through the liquid crystals (slot machine with bonus) to produce the image on the screen.

LCD displays have a fixed resolution, which means that the number of pixels on the screen cannot be changed. This is different from CRT displays, which can be adjusted to display different resolutions. LCD displays are also sensitive to temperature changes, which can affect the quality of the image displayed.

Overall, LCDs are a popular choice for electronic displays because of their thin design, low power consumption, and high image quality.
