What is an OLED TV?
OLED TVs use a display technology called OLED (Organic Light Emitting Diodes) that enables displays that are brighter, more efficient, thinner, flexible and with higher contrast and faster refresh rates than either LCD. Simply put, OLED TVs deliver the best picture quality ever!
OLED TV technology
Each pixel in an OLED TV emits light on its own (in fact each pixel is made from 3 different OLEDs, red, green and blue). OLEDs are truly emissive devices with a simple design which gives them many advantages over current LCD technology:
- High contrast: in OLEDs we have true blacks as when a pixel is off it does not emit any light. In LCDs, the backlighting is always on and so true blacks are impossible to achieve. Even when compared to the latest high-end mini-LED backlit LCDs, the contrast of OLEDs is superior.
- High refresh rates: OLEDs can switch on and off much faster than LCDs.
- Better power consumption: OLEDs only consume light on lit pixels - as opposed to LCDs who always need to use the backlighting. The power consumption of OLEDs depends on the image shown, but in most cases OLEDs will be more efficient than LCDS.
- Flexibility: the simple design of OLEDs enables next-generation flexible, bendable, foldable and even rollable displays. LG is now shipping the world's first rollable TV, the 65" 65RX.

OLED TVs on the market - what can you buy today?
As of 2022, the leading company that produces OLED TV panels is LG Display - making panels ranging from 42-inch to 97-inch. These OLEDs offer the best image quality of all TVs on the market today. LGD is offering its OLED panels to many companies, including LG Electronics, Sony, Vizio and Panasonic.
In 2022 Samsung joined LGD and started to produce its own OLED TV variant, called QD-OLED (which is based on blue OLED emitters and quantum dots color conversion technology). Samsung is producing 55-inch and 65-inch QD-OLED TV panels.
There are dozens of models available today, ranging from entry-level OLED TVs to high-end rollable, bendable and even transparent ones. Click here for the latest OLED TVs on the market.
Reviews of OLED TVs are terrific, and most experts and consumers agree that these OLED TVs are the best TVs ever produced - with virtually perfect image quality and beautiful form factors.
Direct Emission vs WRGB / QD-OLED
The most straightforward OLED architecture uses 3 color OLED sub-pixels (Red, Green and Blue) to create each 'pixel'. This is referred to as a direct emission OLED, and is the design used in mobile OLED displays (for example those used in Apple's latest iPhones and Watches).
For its OLED TVs, however, LG Display is using a different architecture, called WRGB (or WOLED-CF) which uses four white OLED subpixels (each created by using both blue and yellow OLED emitters) with color filters on top (RBG and W). The WRGB technology (developed by Kodak and now owned by LG Display) was found to be easier to scale-up for large-area OLED production, although it suffers from lower efficiency and more complicated design.
As we stated, Samsung's OLED TV architecture is based on blue OLED emitters and quantum-dots color conversion layers.

Samsung officially launches its first OLED TV based on LG's 83" 4K WOLED panels
Samsung officially launched the 83S90C, the company's first TV to use LG's WOLED panels. It uses a 4K 120K 83" OLED display, and is powered by Samsung's AI-powered Neural Quantum Processor. The S83S90C will start shipping in a few days in the US, with a suggested price of $5,400.
Interestingly, Samsung decided to have its first WOLED TV sit in the same range as its QD-OLED TVs, the S90C, which includes 55-, 65- and 77-inch QD-OLED TV panels. It's likely the company will try to blur the differences between the QD-OLED and the WOLED panels, and not discuss too much its reliance on LG Display's supply.

What can deuterium do for OLED displays?
The following is a sponsored post by Cambridge Isotope Laboratories
OLED has become the display technology of choice for many commercial products such as smartphones, laptops, tablets, TVs, automotive dashboards and wearables. OLED has advantages with improved image quality (better contrast, higher brightness, fuller viewing angle, wider color range, and faster refresh rates), lower power consumption, and simpler designs (ultra-thin, flexible, foldable, and transparent displays).

OLED, however, faces several technical challenges. While OLED TVs yield better picture quality than common LCDs, they are usually less bright. Research using a compound that has at least one hydrogen replaced with its heavier isotope, deuterium, is showing promise toward achieving greater brightness. Since the bonds between carbon and deuterium are stronger than those between carbon and hydrogen, materials made with deuterated compounds tend to have a longer lifetime, which allows OLED displays to run brighter but still last as long.
