VIENNA (Reuters) – Apple supplier AMS has a light and infrared proximity sensor that can sit behind a smartphone screen, reducing the area required for such sensors, and so for a bigger view, AMS said on Monday.

AMS provides Apple with optical sensors for 3D face recognition features on the latest iPhones. The shares slid by a fifth on Thursday, after Apple issued a sales warning, though they have now of that.

AMS, an Austrian company listed in Switzerland, does not identify Apple as a customer, but analysts estimate that the US tech giant accounts for about 45 percent of the revenue.

“By developing this ‘behind OLED’ ambient light/proximity sensor, AMS enables smartphone manufacturers to achieve the highest possible ratio of displayed area to body size,” AMS said in a statement on the launch of the new device, referring to the OLED display technology used in devices such as the latest iPhones.

“The TCS3701 the phone designers of this trend to a new level, possibly eliminating the bezel entirely,” AMS said, with the new name displayed. The bezel is the border between a smartphone screen and the frame.

Light sensors are used for adjusting the brightness of the display, while infrared sensors are used in areas such as facial recognition.

AMS’s shares closed up 9.6 percent, but they peaked earlier in the session after the company announced a deal with the Chinese software maker Face++ for the production of a new 3D facial recognition for smartphones.
