taustavalonlähteitä
Taustavalonlähteitä, or backlight sources, are fundamental components in many display technologies. Their primary function is to provide illumination that allows images to be visible on the screen. Without a backlight, technologies like Liquid Crystal Displays (LCDs) would appear dark and unreadable, as they themselves do not emit light but rather control the passage of light through them.
Historically, Cold Cathode Fluorescent Lamps (CCFLs) were the dominant backlight technology for LCD screens. These lamps
The advent of Light Emitting Diodes (LEDs) revolutionized backlight solutions. LEDs offer significant advantages over CCFLs,
