OLED monitors: introduction and industry news
OLED (Organic Light Emitting Diode) technology offers bright, efficient and fast displays, outperforming LCD display. OLEDs deliver the best picture quality ever and are used in many devices, from smartwatches through smartphones and tablets to TVs and more.
OLEDs are also used to enable high-end monitors that offer excellent contrast, image quality, colors and new form factors. This article will explain the benefits, the current status and the future of OLED monitors.
OLED monitors vs LCD monitors
- OLED provide a better image quality with a much higher contrast (true blacks), wide color gamut, better viewing angles and a much faster refresh rate (great for gaming!)
- OLED panels are much thinner and lighter compared to LCD panels
- OLED monitors consume less power - as only lit pixels draw energy on OLED displays
- An OLED monitor can be flexible, bendable, rollable - and transparent
Of course OLED technology is not perfect. One of the major drawbacks of an OLED display is image retention / burn-in. In an OLED display each pixel is driven independently and each pixel ages differently - and as brightness is reduced with use (the lifetime of OLED materials is limited), we have burn-in problems.
For mobile phones and TVs this is less of a problem - but in a computer user interface many UI elements are quite fixed (toolbars, icons, etc) which means that burn-in is a real problem. There are some technologies to handle this problem - for example by measurement and compensation, or by adopting a tandem architecture to increase the lifetime. In addition user-interface designers can design a user interface that will be more suited for OLED displays. As there are already millions of OLED monitors on the market, it seems that this problem has been mostly solved.
OLED monitors on the market
OLED technology is very popular in smartphones, wearables and TVs - and in recent years OLED monitors has entered the market as display makers now target this market, starting with high-end models aimed towards gaming and content creation. OLED producers, led by LG Display (WOLED) and Samsung Display (QD-OLED) are offering several high-end OLED panels for monitor makers, and today many leading monitor producers have already adopted OLED displays in their high-end models - including LG Electronics, Samsung, Viewsonic, Asus, Dell, Acer and more.
