Defining LCD LED TVs
Before diving into the specifics, it’s essential to clarify what we mean by LCD LED TVs. The term “LCD LED TV” can often be confusing, as it merges two distinct technologies: Liquid Crystal Display (LCD) and Light Emitting Diode (LED) technology.
What is an LCD?
Liquid Crystal Display (LCD) is a flat-panel technology commonly used in televisions and computer monitors. The core principle behind LCDs involves manipulating light through liquid crystals sandwiched between layers of glass.
How Does LCD Work?
LCD screens require a backlight to illuminate the image since liquid crystals do not emit light on their own. Here’s a brief overview of how the technology functions:
- Backlighting: The backlight is typically fluorescent or, in modern displays, LED-based.
- Polarization: Light from the backlight passes through a polarizing filter that allows only certain light waves to pass through.
- Liquid Crystal Layer: The light then travels through a layer of liquid crystals that can twist and block light based on electric currents.
- Image Production: Finally, the light passes through a second polarizing filter and displays the image on the screen.
What is LED Technology?
Light Emitting Diode (LED) technology refers to the use of diodes that emit light when an electric current is applied. LED TVs essentially use LEDs as the source of backlighting instead of traditional fluorescent tubes.
Types of LED Backlighting
There are primarily two types of LED backlighting for LCD TVs:
- Edge-Lit LED: LEDs are placed around the edges of the screen, which helps to create a slimmer profile but may result in less uniform lighting.
- Full-Array LED: LEDs are placed directly behind the LCD panel in a grid pattern, offering better control over brightness and contrast.
