Well, the LG Signature OLED R is finally available to purchase, which means you can now enjoy a stylish TV with an OLED screen that rolls down and disappears in the comfort of your own home. LG first announced its rollable OLED TV at CES 2019, and since then we've been waiting patiently for this seemingly magical concept television to actually ship.

Like LCD, OLED is well suited to accommodate new video technologies like 4K resolution, a wider color gamut, and High Dynamic Range capability. Panasonic has also continued its OLED development, although the company has yet to introduce an OLED TV to the U.S. You can view the company's complete lineup here. LG has remained committed to OLED and has brought many models to market, in sizes up to 78 inches. Sony and Samsung never introduced new OLED TVs to market after the ones described above. TV manufacturers encountered a number of stumbling blocks in trying to bring large-screen OLED TVs to market-namely, it is expensive to produce at large screen sizes, and the yield rate (the number of defect-free models that can be sold) was low-causing companies like Samsung, Sony, and Panasonic to abandon or at least postpone their OLED TV development efforts. In addition to red, green, and blue color filters within each pixel, LG adds a clear filter that allows white light to pass through, which is designed to improve brightness and efficiency. LG's approach is called White OLED (or WOLED), which uses RGB color layers that are applied to the organic layer and act as color filters for the light being emitted. Samsung used RGB OLED, in which each pixel contains a red, green, and blue sub-pixel laid directly on the display panel, which eliminates the need for color filters. ![]() ![]() Samsung and LG use different approaches in creating an OLED pixel. You can read our review of the first Samsung OLED TV here. We did not see a large-screen OLED TV until 2013, when Samsung and LG both brought 55-inch panels to market. In the TV realm, Sony was the first company to introduce an OLED monitor back in 2008: the 11-inch XEL-1. OLED technology is currently used in many personal electronic devices, like cell phones, portable audio players, etc. Beyond their potential to produce an amazing contrast ratio, OLED TVs can have a wider viewing angle than LCD, they can produce less motion blur, and they can be packaged in an even thinner, lighter cabinet that can even be flexible. An OLED display generally can't be as bright as an LCD, but it is capable of more light output than a plasma display. Therefore, it is better able to produce a true black (no electric current equals no light). When the compound receives an electric current, it emits light.īecause an OLED can generate its own light (as plasma could), it does not require the use of a backlighting or edge-lighting system the way LCD does. An OLED consists of a thin film of organic carbon-based compounds sandwiched between two electrodes. OLED stands for Organic Light-Emitting Diode, and OLED technology is an alternative to LCD and (the now deceased) plasma technologies in display production. ![]()
