![]() ![]() This affects some aspects of picture quality, which we discuss in more detail below. The lights illuminate the crystals fairly evenly, which means all regions of the picture will have similar brightness levels. CCFL BacklightingĬCFL backlighting is an older, now-abandoned form of display technology in which a series of cold cathode lamps sit across the inside of the TV behind the LCD. Each of these illumination technologies is different from one another in important ways. ![]() Three basic illumination forms have been used in LCD TVs: CCFL backlighting, full-array LED backlighting, and LED edge lighting. For those interested, we’ll go deeper into backlighting below, or you can move onto the Local Dimming section. Since the technology is better, all LCD TVs now use LED lights and are colloquially considered LED TVs. Older LCD TVs used cold cathode fluorescent lamps (CCFLs) to provide lighting, whereas LED LCD TVs used an array of smaller, more efficient light-emitting diodes (LEDs) to illuminate the screen. Since both LED and LCD TVs are based around LCD technology, the question remains: what is the difference? Actually, it’s about what the difference was. Think of it as a shutter, either allowing light to pass through or blocking it out. When an electric current passes through the liquid, it causes the crystals to align, so that light can (or can’t) pass through. ![]() These panels are typically composed of two sheets of polarizing material with a liquid crystal solution between them. Sony releases its 2023 TV prices with one very big exceptionĭespite having a different acronym, LED TV is just a specific type of LCD TV, which uses a liquid crystal display (LCD) panel to control where light is displayed on your screen.
