The key difference lies in the backlighting technology. Here's a breakdown: * How it works: Instead of the older Cold Cathode Fluorescent Lamps (CCFLs) used in traditional LCDs, LED TVs use Light Emitting Diodes (LEDs) to illuminate the LCD panel. The LCD panel itself is responsible for creating the image by selectively blocking or allowing light to pass through its pixels. The LEDs provide the light source. * Advantages of LED backlighting: * Improved Picture Quality: LEDs offer better brightness, contrast, and a wider color spectrum compared to CCFLs, leading to more vivid and immersive viewing experiences. * Deeper Blacks: Full-array LED TVs (where LEDs are placed behind the entire screen) with local dimming can achieve significantly deeper blacks by selectively dimming individual zones of LEDs. * Energy Efficiency: LEDs consume less power than CCFLs, making LED TVs more energy-efficient. * Slimmer Design: LEDs are smaller than fluorescent lamps, allowing manufacturers to create much thinner and lighter TV designs. * Longer Lifespan: LEDs generally have a longer lifespan than CCFL backlights. * Types of LED Backlighting: * Edge-lit LED: LEDs are placed around the edges of the screen, and light is directed across the panel using a diffuser. This allows for very thin designs but can sometimes lead to uneven backlighting. * Full-array LED: LEDs are placed directly behind the entire screen, often in zones that can be individually dimmed (local dimming). This provides more precise control over brightness and contrast, resulting in superior picture quality, especially with HDR content. * Evolution of LED TVs: * QLED (Quantum Dot LED): This is an enhancement of LED technology, primarily championed by Samsung. QLED TVs use an additional layer of "quantum dots" between the LED backlight and the LCD panel. These tiny semiconductor crystals emit specific colors when exposed to light, significantly boosting color volume, brightness, and color accuracy. They are still LED-backlit LCD TVs. * Mini-LED: This is another evolution that uses thousands of tiny LEDs for backlighting, arranged in many more dimming zones than standard full-array LED. This allows for even finer control over contrast, deeper blacks, and brighter highlights, getting closer to OLED performance in some aspects. * QNED: LG's technology that combines Quantum Dot and Nanocell technology with Mini-LED backlighting. * Distinction from OLED: It's important to differentiate LED TVs from OLED (Organic Light Emitting Diode) TVs. OLEDs are a completely different display technology where each individual pixel emits its own light. This means OLED TVs don't require a backlight, allowing for perfect blacks, infinite contrast, and extremely thin designs. Popular LED TV Brands in India (as of 2024/2025): Some of the leading brands offering LED (and their advanced variations like QLED, Mini-LED) TVs in India include: * Samsung * LG * Sony * Xiaomi (Mi/Redmi) * TCL * Hisense * Acer * Vu * OnePlus * Panasonic * Haier * Toshiba * Croma (store brand) * Motorola * Infinix * Realme * BPL When choosing an LED TV, consider factors like: * Screen Size * Resolution (Full HD, 4K Ultra HD) * Smart TV features (operating system like Android TV, Google TV, WebOS, Tizen) * HDR support (HDR10, Dolby Vision) * Picture Quality technologies (Local Dimming, Quantum Dots) * Audio Quality (Dolby Atmos, wattage) * Connectivity (HDMI ports, USB ports) * Refresh Rate (important for gaming) * Budget
