TVs and monitors

OLCD provides a route to ultra-high contrast TVs and monitors.

HDR TVPicture quality is one of the most important display features when it comes to TVs and monitors. OLED TVs provide ultra-high contrast thank to pixel dimming - every single pixel generates light itself and turns on/off independently achieving excellent black level. However, OLED TVs are a premium market due to their higher price. 

LCD TVs are lower cost and dominate the TV market, but haven’t been able to achieve the ultra-high contrast performance of OLED TVs.

Ultra-high contrast dual cell LCD TVs

Recent developments in glass LCD technology have made it possible to increase the LCD contrast by stacking two LCD displays on top of each other: dual cell LCDs. While this approach significantly improves the contrast ratio of the display, the display becomes much thicker as four sheets of glass are required which also adds to the cost of the module and requires a brighter backlight. Another disadvantage of this approach is that there is a large separation between the two cells (i.e. two pixels placed on top of each other) caused by the two layers of glass in between. This means that the dimming effect is spread over many tens of pixels or more which does not provide the pixel-level contrast performance of an OLED TV.

The issues of increased thickness and lack of true pixel-level local dimming can be overcome with FlexEnable’s OLCD technology. The TAC film onto which OLCD is build, is ten times thinner than glass, meaning that the two cells can be brought together with a separation that is much smaller than the pixel pitch for a TV. In addition, the display architecture becomes much thinner and it can be manufactured in a simpler way (than dual cell glass LCD and OLED) at lower cost with higher optical performance.

Since OLCD is highly scalable to large Gen size lines for large area displays, it can be implemented in today’s Gen 8/9/10 lines and produce the same large sizes as glass LCDs today.
