Smile for a selfie. Most smartphone users today use their phones to take photos and more specifically selfies. But where did the word 'selfie' originate? The selfie terminology was coined ten years ago from an Australian posting a photo of his injured lip with a caption "... sorry about the focus, it was a selfie".
Today people worldwide are taking selfies with their smartphones. But the selfie camera takes up extra room, room that limits the size of the display while making the phone larger. There is therefore a great demand to hide the camera under the display, eliminating the typical border, or notch, above the display.This ability to have a camera underneath the surface of a smartphone screen comes with its own development and production challenges.
One of these challenges is the pixels of the OLED display and its uniformity. The display in front of the camera interfere with the light reaching the camera sensor resulting in unclear and blurry images. And the camera can be seen behind the display. Careful measurements of the small area in front of the camera are used to correct these effects using software.
Konica Minolta Sensing's CA-VP402 display analyzer probe is an instrument that is able to address this need.
