Mobile devices

OLCD provides a route to borderless large area displays for mobile devices.

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 other mobile devices such as notebooks and tablets. 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 areas display products such as notebooks.

OLCD enables borderless displays

Notebook with borderless OLCDThe bezels on mobile devices exist because electronics circuitry and wiring is needed around the edge of the displays to connect the pixels to the outside world. Organic LCD (OLCD) provides a route to borderless displays through curved edges and folded borders. It is cost-effectively scalable to large sizes and is therefore suitable to replace the glass displays in notebooks and tablets.

OLCD also brings other advantages to notebooks and tablets by enabling 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.
