Classical LED/LCD TVs, also known as liquid crystal display televisions, have been a staple in home entertainment for decades. Here are some key points about them:
Display Technology: LCD TVs use liquid crystal displays to produce images. These crystals do not emit light on their own; instead, they modulate light produced by a backlight.
Backlighting: In LED/LCD TVs, the backlight is typically provided by LEDs (light-emitting diodes) placed behind the LCD panel. This backlight shines through the liquid crystal layer to produce the images on the screen.
Resolution: LED/LCD TVs come in various resolutions, including HD (720p), Full HD (1080p), and Ultra HD (4K). The resolution determines the clarity and detail of the images displayed.
Contrast Ratio: Contrast ratio refers to the difference between the brightest and darkest parts of an image. Higher contrast ratios generally result in better image quality, with more vivid colors and deeper blacks.
Refresh Rate: The refresh rate indicates how many times per second the image on the screen is refreshed. Higher refresh rates, such as 60Hz, 120Hz, or even 240Hz, can result in smoother motion and reduce motion blur, especially during fast-paced scenes.
Smart Features: Many modern LED/LCD TVs come with smart features, allowing users to access streaming services, browse the internet, and run apps directly on the TV.
Connectivity: LED/LCD TVs typically offer various connectivity options, including HDMI, USB, Ethernet, and wireless connections like Wi-Fi and Bluetooth, allowing users to connect external devices such as gaming consoles, Blu-ray players, and sound systems.
Energy Efficiency: LED backlighting is generally more energy-efficient compared to traditional CCFL (cold cathode fluorescent lamp) backlighting used in older LCD TVs, resulting in lower power consumption and potentially lower electricity bills.
Overall, LED/LCD TVs have been popular due to their relatively affordable pricing, wide availability, and versatility in terms of features and screen sizes. However, they are gradually being phased out in favor of newer display technologies like OLED and QLED TVs, which offer superior picture quality and thinner form factors.
