OLED Advantages

The different manufacturing process of OLEDs lends itself to several advantages over flat panel displays made with LCD technology. Lower cost in the future OLEDs can be printed onto any suitable substrate by an inkjet printer or even by screen printing,[53] theoretically making them cheaper to produce than LCD or plasma displays. However, fabrication of the OLED substrate is more costly than that of a TFT LCD, until mass production methods lower cost through scalability. Roll-roll vapour-deposition methods for organic devices do allow mass production of thousands of devices per minute for minimal cost, although this technique also induces problems in that multi-layer devices can be challenging to make due to registration issues, lining up the different printed layers to the required degree of accuracy. Light weight & flexible plastic substrates OLED displays can be fabricated on flexible plastic substrates leading to the possibility of flexible organic light-emitting diodes being fabricated or other new applications such as roll-up displays embedded in fabrics or clothing. As the substrate used can be flexible such as PET,[54] the displays may be produced inexpensively. Wider viewing angles & improved brightness OLEDs can enable a greater artificial contrast ratio (both dynamic range and static, measured in purely dark conditions) and viewing angle compared to LCDs because OLED pixels directly emit light. OLED pixel colours appear correct and unshifted, even as the viewing angle approaches 90° from normal. Better power efficiency LCDs filter the light emitted from a backlight, allowing a small fraction of light through so they cannot show true black, while an inactive OLED element does not produce light or consume power.[55] Response time OLEDs can also have a faster response time than standard LCD screens. Whereas LCD displays are capable of between 2 and 16 ms response time offering a refresh rate of 60 to 480 Hz, an OLED can theoretically have less than 0.01 ms response time, enabling up to 100,000 Hz refresh rate.
