Jargon Explained #2

It seems like there are always new television technologies being released and here we explain a few of them.

OLED (Organic Light Emitting Diode) - Unlike an LED/LCD television screen where light from LEDs is blocked from, or allowed through to, the front of the screen to produce variations in brightness and colour (the picture you see) an OLED screen produces light and colour directly from each individual pixel (the OLEDs). This means much better contrast (the difference between black and white) and more realistic colours, plus the physical screen can be made much slimmer. LG own this technology so any OLED tv will use an LG panel.

QLED (Quantum Dot Light Emitting Diode) - is an LED/LCD screen with a layer of ‘quantum dots’ and special blue LED added to create a better picture, pure whites and high brightness levels. It is a technology unique to Samsung and is nothing like OLED.

HDR (High Dynamic Range) is one of the latest technologies for 4K televisions and 4K content. The term originates in photography and refers to the technique to heighten a picture’s dynamic range – or contrast between the brightest whites and darkest blacks. This technology therefore gives you more detail to what is being shown on screen. Colours will be richer and more life-like and details will be more easily seen, making the picture more natural, more as you would see it in real life.


HDMI ARC (Audio Return Channel) – This input differs from the other HDMI connections by allowing audio to pass back down the HDMI cable in a compatible soundbar or AV receiver. A feature of most modern televisions, there is usually only one HDMI input that supports ARC.


CEC (Consumer Electronics Control) is a feature of HDMI which allows compatible devices connected via an HDMI cable to be controlled by the product they are connected to. For example, a tv being able to control a soundbar or DVD player when both products have the CEC feature. This way you only need one remote control, the tv remote.
