    Yes I like that Samsung, getting a bit confused to what’s on offer tbh, my thinking is lcd back lit ok in its day however would be better off going for a mini led, or a q Ned,q led or better still a oled, however then you get into q led evo type stuff going upto £25.000.. Suddenly q led/mini led sounds great

    Evo are next generation OLEDs by LG. Samsung calls them QD OLED  and so on. They are extremely bright, perhaps too bright and expensive.

    LCD is the panel/screen type, which require a back light. Older TV’s like your use cold cathode fluorescent lamps as the backlight. Newer ones use LED as a backlight. This type of TV can be edge lit, backlit or have an array of local dimming zones. These TV’s produce 300-600 nits peak brightness

    QLED or Quantum dot what ever the manufacturer calls it, is a LED backlit LCD TV as above, that also use electrically charged semoconducturs nanocrystals (quantum dots) layer. A quantum Dot TV produces brighter and more vibrant and accurate colours. As above it can be edge lit, backlit or have local dimming zones. These TV produce 300-800 nit peak brightness.

    A Mini LED TV uses an LCD screen but, use miniture LED’s as a backlight. The use of mini LED’s allows the manufacturer to use more LEDs as a backlight. They are alot brighter than the above TV’s producing between 900 – 2000 nits peak brightness, making them even brighter and perhaps the bigger advantage is they have far more local array dimming zones upwards of 150 depending on the price you pay. They also use Quantum Dot technology.

    An OLED TV does not need an LCD screen or backlight. OLED (organic light emitting diodes) produce there own light  on a thin panel, that has a much harder glass/perspex outer layer making them easier to clean. Each pixel on an OLED TV has four individual subpixels (WRGB), which are never all on at the same time. OLEDs are able to individually dim, turn on or off pixels, resulting in an infinite contrast ratio that produces deep and inky blacks and a better overall image. Due to the ability to dim, turn on or off each of the 8,294,400 to create indvidual local dimming zones, thus does not suffer any picture blooming as the other tv types and provides an even spread of light throghout the screen. 99% of OLEDS use screens manufacturerd by LG. OLED’s like the Hisense A85 and LG C1/2 produce aeound 800 nits peak brightness.

    EVO, QD OLED use a much bigger heat sink or slighty different subpixel layout. These TV’s can produce the same peak brightness as seen in mini LED’s, whils’t retaining a stunning pictue quality. I have the first of LG’s EVO panels (LG G1), that is said to be 20% brighter than a traditional OLED. To my naked eye I can’t really tell much of a difference and certainly not 20% worth compared to my old OLED. Of course the later ones will be massively brighter but retain the same picture quality and as you said they are expensive.

    One of the main benifits of an OLED is they take the guess work out of choosing a TV because, you can’t get a bad one – the picture quality will look much the same as the next with a narrower gap between manufactures compared to LCD type’s which can be mind field choosing one. However each persons budget dictates what they can afford and get the best for their £’s
