Flexible OLED Display
Nowadays, traditional paperback dictionaries are seemingly becoming obsolete as more consumers are turning to electronic dictionaries for their portability as well as versatility. With the emergence of next-generation flexible displays, experts predict that heavy notebook computers may also become outdated in the near future.
Recently, a Korean firm unveiled an ultra-thin flat panel that allows users to access information rolled up in e-papers. Developed by Samsung Mobile Display, the full-color flexible organic light emitting diode (OLED) panel is thin, light, and can be rolled up like paper. The new display is 0.02mm thick, which is 1/10 of thickness of human hair, and weighs 0.29g, which is roughly 1/3 of weight of a bank note. Their new product is reported to be the slimmest and the lightest phone in the world as it incorporates a durable display panel. Even when dropped or hammered, the ultra thin display panel does not break and has the ability to show vivid color range.
Rolled-Up Electronic Appliances
How is it possible that the OLED enhances durability and aesthetic appeal of high-end gadgets? Experts claim that the answer lies in the special plastic component that is used instead of glass plates.
The liquid crystal display (LCD) is widely used in a variety of electronic appliances like mobile phones, MP3 players, televisions, washers, and more. Despite its wide use, LCD has its drawbacks. The liquid crystal of LCDs cannot produce light on its own, and thus must depend on backlights. In addition, the surface of LCD panel is made up of glass plate, and is thus subject to frequent damage. In order to make up for such shortcomings, Samsung Mobile Display chose to manufacture next generation flat panels by switching the glass plate into plastic.
Use of Plastic In Lieu of Glass
The process of making LCDs involves converting the silicon into a semiconductor, which produces a great amount of heat at 500 degrees Celsius. Naturally, it makes it difficult for plastic to survive the extremely high temperature. But with the use of plastic instead of glass plates, next-generation flat screens can be bent or rolled up like a scroll. Given these rewards, many leading flat panel suppliers have invested time and their tireless efforts to produce flexible OLED panels. Applying the innovative technology, those produced by the Korean firm do not come with glass plates as frames. Before the recent technology was introduced, flat panel suppliers had to undergo heating the displays at low temperatures to make sure the glue did not melt. Without the plates, it is unnecessary to go through such complicated processes anymore; the new technology allows suppliers to produce wearable displays including watch-like mobile phones, electronic books and passports at lower costs.
