What is flexible OLCD?


Although flexible OLEDs are now widely used in flagship smart phones and smart watches and other products, there is no low-cost alternative display technology that can be used for mainstream applications that require large-size displays (such as smart home devices, car monitors, etc.). And digital billboards) to provide curved displays. However, the latest development of flexible organic LCD (OLCD) technology has opened up a new design dimension for the broader display market.


 


     Unlike glass substrate LCDs, OLCD uses organic materials as substrates instead of amorphous silicon transistors. The temperature required to produce these organic transistors is much lower, so flexible biological substrates as thin as 40 microns—such as triacetyl cellulose (TAC)—can be used to obtain conformable, plastic thin and light OLCDs. It does not damage its optical display performance, and has the same large-scale scalability as glass LCD.


   OLCD can not only achieve a more aesthetic product appearance, but its softness can also fold the edges behind the display to achieve an ultra-narrow bezel. This brings huge advantages to applications such as notebook computers and tablet computers. The absence of borders means that devices of the same size can achieve larger display sizes. OLCD technology can also produce ultra-high contrast dual cell displays with true pixel-level dimming functions, thereby providing OLED-like performance at a very low cost.


Compared with glass displays, extremely thin OLCD substrates have advantages in terms of cost, viewing angle, and module thickness, while retaining the flexibility required for various applications, such as surface-integrated automotive displays. This new technology represents a major advancement in the display industry. OLCD has entered mass production in Asia, and for the first time both large and small screens have been manufactured on flexible substrates.
