BUYING GUIDE FOR TElevision
Types of LED TV:
The LED (Light-emitting Diode) Televisions are divided on the type of backlighting it has. Hence, they are divided into two major types, namely, Edge Lighting and Direct Lighting. Both types come in different variations and may or may not have local dimming.
· Full LED TV or Direct-lit LED TV:
Full LED or commonly referred to as full-array or direct-lit LED, have the LED lights arranged behind the entire LCD panel covering all the area of the panel. Their design is thicker than other LEDs and have the picture quality similar to LCDs.
· Edge-Lit LED TV:
Like the name suggests, this type of LED have a sequence of LED backlights that run along the outside edges of the screen, which are spread across the entire screen by light guides. Due to this alignment, manufacturers have been able to reduce the thickness of the TV and also reduce costs. This type of design increases the brightness around the edge of the screen and gradually decreases the depth of the blacks, but it is not noticeable when it is viewed in brightly lit rooms.
· Local Dimming in LED TVs:
Some LED televisions use local dimming, which simply means either individual LEDs or groups of LEDs can be dimmed or brightened autonomously of one another. Most frequently, local dimming is found in LED televisions with full-array LED backlighting. This design offers significant improvement over other LCD TVs when it comes to black levels and uniformity.
There are also edge-lit LED televisions that use a type of local dimming sometimes called as 'micro dimming”.
The OLED TV uses a new display technology called the OLED (Organic Light-emitting Diode) which has revolutionized how TVs are classified. OLED displays are made by employing thin films of organic materials between two conductors. When electrical current is applied, light is emitted. OLED displays are emissive and do not require a backlight. OLED has quicker refresh rate, better contrast and better color reproduction. OLED offers a 180-degree viewing angle.
QLED TVs are a type LED TVs that use quantum dots to enhance performance in key picture quality areas. Quantum dots operate exactly like a filter that produces purer light than LEDs alone can offer. Quantum dots do not directly emit the colors you see. They’re spread on a piece of film that acts almost as a filter within an LED TV panel. Essentially, LED backlights beam through this film, the light is polished to an ideal color temperature, and afterwards, the brightness and color are significantly enhanced.
· Curved Screen TV:
The emergence of Curved TVs has totally changed how one watches breathtaking visuals and help in enhancing the TV watching experience. The curving of the screen helps in wrapping the image around your peripheral vision and you have an immersive experience. A curved screen often mimics a 3D screen and gives a 3-dimensional experience. Curved TVs are said to provide wider viewing angles, theoretically and give you a grandiose viewing experience.
· Smart TV:
In simple words, Smart TV is nothing but any TV that can be connected to the internet to access streaming media services and that can run entertainment apps, such as on-demand video-rental services, internet music stations and web browsers. You can play games, stream YouTube videos and access all the internet through a Smart TV.
