What is LCD Technology?
Liquid Crystal Display (LCD) technology has been a staple in the television industry for many years. It utilizes a liquid crystal solution sandwiched between two layers of glass or plastic. LCD TVs create images by blocking light in various ways to form distinct colors. Here’s a closer look at how it works:
How LCD TVs Work
LCD TVs rely on a backlight to illuminate the liquid crystals, which modulate the backlight to create images. The three main components of an LCD screen are:
- Liquid Crystals: These are the key players in an LCD screen. They change orientation when an electric current is applied, thus controlling the amount of light that passes through.
- Backlight: LCDs require a backlight as they are not inherently luminous. Originally, cold cathode fluorescent lamps (CCFL) were used, but today, LEDs are predominantly used for backlighting, leading to the term “LED TVs.”
- Filters: Color filters are used to produce the RGB (red, green, blue) colors necessary for creating images.
Understanding LED Technology
LED, or Light Emitting Diode technology, is often associated with LCD because most modern LED TVs use an LCD screen with LED lighting. However, there are direct LED TVs that operate without the LCD mechanism.
How LED TVs Work
In LED TVs, the core technology remains LCD, but the difference lies mainly in the type of backlighting used:
- Edge-Lit LED: LEDs are placed around the edges of the screen. This allows for slim designs but can affect uniformity in brightness.
- Full-Array LED: LEDs are distributed across the entire back of the screen. This design provides better control over brightness and contrast, as some sections can be dimmed or turned off completely.
Key Differences Between LCD and LED TVs
