CCFLtaustvalgustused

CCFL taustvalgustused refers to Cold Cathode Fluorescent Lamp backlighting. These lamps were a common technology used to illuminate LCD screens in monitors, televisions, and laptops before the widespread adoption of LED backlighting. A CCFL is a type of fluorescent lamp that operates at a lower temperature than traditional hot cathode fluorescent lamps. In a CCFL backlight system, a series of these lamps are positioned behind the LCD panel. Light emitted by the CCFLs passes through diffusers and filters to provide even illumination for the pixels on the screen, allowing images to be visible. CCFLs typically require an inverter to convert the low DC voltage from the device's power supply into the high AC voltage needed to start and maintain the plasma discharge within the lamp. While offering good color reproduction and brightness, CCFLs have several disadvantages compared to modern LED backlighting. They are less energy-efficient, generate more heat, have a shorter lifespan, and are generally thicker, contributing to bulkier device designs. Furthermore, their mercury content poses an environmental concern. The transition to LED backlighting has largely replaced CCFLs due to their superior energy efficiency, thinner profiles, longer lifespans, and better dimming capabilities.
