LCDteknologiaan

LCDteknologiaan refers to Liquid Crystal Display technology. This technology is a flat-panel display that utilizes the light-modulating properties of liquid crystals. Liquid crystals do not emit light on their own; instead, they require a backlight or a reflector to produce an image. In a typical LCD, a backlight, often made of LEDs, shines through a series of polarizing filters and liquid crystal cells. Each pixel in an LCD is made up of these liquid crystal cells. By applying an electric voltage to these cells, the orientation of the liquid crystal molecules can be changed. This change in orientation affects how polarized light passes through them. Different voltages result in different amounts of light passing through, which can be controlled to create various shades of gray. Color is achieved by adding color filters to the sub-pixels, typically red, green, and blue. By controlling the amount of light that passes through each of these color sub-pixels, a wide range of colors can be produced. LCDs are widely used in televisions, computer monitors, smartphones, and many other electronic devices due to their relatively low cost, good color reproduction, and energy efficiency. Advancements in LCD technology have led to improved refresh rates, contrast ratios, and viewing angles over the years.
