LG G7 Coming with an Advanced Iris Scanner; Patent Reveals
LG has had a lot of success with the release of the G6 this year in Feb and the G5 in 2015. The next year’s G7 2018 will be coming with an 18:9 Full-Screen display with very minimum bezels, and according to a new report, the G7 will be featuring an iris scanner. There were reports that both Samsung and LG were developing a biometric authentication method in the form of an iris scanner. This was confirmed after LG showed a working iris scanner module at the Korea Electronics Show (KES).
The two smartphone manufacturers both omitted the iris scanner from their past flagships. LG on the G6 and the G5, while Samsung on the Galaxy Note 7. Samsung has already included it on the S8 and the S8+, which will likely remain in the S9 flagship series. Next month, both the flagships are expected, and there is a great change in the LG G7 coming with an iris scanner. Even new evidence shows that LG is still working on its iris scanner in the background.
The biometric scanner scans the properties of the iris with infrared light. During KES, LG showed a camera that can switch between infrared light and the rest of the color spectrum. This one camera can function as a front and iris scanner. This will save money. LG applied for this patent in mid-2017 at WIPO, which was recently assigned. The patent describes the working of the iris scanner, too.
An iris scanner cannot scan an iris properly when the person is not directly in front of the camera or when the ambient light is insufficient. Also, pupil size differs because of the ambient light and the distance from the eye to the display. And in many cases, people have cracked the security using photos, so LG has provided a solution. The device records an iris image, which it stores in the memory. An exposure sensor can detect the ambient light, and the display emits light from a preset area. The camera then detects a second iris photo or a pupil. Then, these images are compared, and if they match, authentication is registered. Still, if it doesn’t match, the display illumination is automatically adjusted to detect differences in the pupil size. Further, smartphones even provide a pattern or image to look at, which can detect and follow your pupil’s movements, preventing the use of photos.
There is a high probability that the LG G7 will appear at CES 2018, which will be held one month later. We will get more details about the iris scanner and the device there.
