Laser-etched hole to enable exceptional camera performance in new Samsung smartphone

Share this on social media:

Samsung Display has developed an extremely small, laser-etched hole that will be located near the top front of the flexible polyimide OLED displays of the Galaxy Note10 and Note10+ – due to go on sale tomorrow – through which photos can be shot without any loss in picture quality.

The firm’s laser ‘hole-punching’ technology enables the creation of a completely independent photo-shooting pathway only 4.7mm in diameter between the OLED panels of the two new smartphones. This is much smaller than the space in the Galaxy S10’s hole design. The display enhancement is said to offer exceptional uniformity of image quality and transmissivity of light.

The new camera hole retains an unimpeded 92 per cent of high light transmissivity, which means a camera shooting through it will boast the same performance as the protruded cameras of conventional smartphones, even though the new hole has been poked directly through the display.

‘Representing a major advancement in display design, this extremely small hole in our flexible OLED display allows for picture-taking that is as consistently excellent as that of other premium smartphones,’ a Samsung Display official said. ‘This much-improved space utilization will take smartphones to the next level of design efficiency in the future.’

Overall, Samsung said the superb performance of its 4.7mm laser-cut hole is attributable to the OLED display’s flexibility, its simple yet rugged features, and the state-of-the art laser cutting techniques used to make each camera hole.

While Samsung hasn't specified which type of laser was used to create the new holes, Dr Arnold Gillner of Fraunhofer ILT informed Laser Systems Europe readers recently that ultrafast lasers are increasingly being used to cut holes in displays to create openings for camera lenses.
