OLCD enables bezel-less displays for notebooks and tablets.

In the last few years there has been a trend to reduce the size of the bezel on mobile devices. This trend has started with smartphones where it is driven by consumers’ requirements for larger screens without necessarily increasing the size of the device.

The same drivers are now leading to a trend to reduce bezels on notebooks and tablets as well. Many notebooks and tablets today can have bezel sizes up to around 1-2cm on each side. Removing these bezels could nearly allow a 15” display to fit into today’s 13” notebook casing. Some notebooks with glass displays have smaller borders than this today (3-4mm), but it is recognised that going much smaller requires flexible displays such as OLED or OLCD. However, the high cost of today’s flexible OLED displays is why they are not used in mass market large area display products such as notebooks.

Notebook with borderless OLCDThe bezels on mobile devices exist because electronic circuitry and wiring is needed around the edge of the displays to connect the pixels to the outside world. FlexEnable has demonstrated that its Organic LCD (OLCD) technology enables bezel-less displays through curved edges and folded borders. OLCD is cost-effectively scalable to large sizes and is therefore suitable to replace the glass displays in notebooks and tablets. It also brings other advantages to notebooks and tablets by allowing thinner, lighter and shatterproof screens. Lighter and shatterproof screens have clear benefits for users, and thinner screens can improve the overall performance of the device by freeing up space that can be used for additional battery capacity or processing power.
