Since the introduction of the on-screen fingerprint recognition technology, it has courted lots of interest from fans who are always on the lookout for that piece of tech on any new flagship phone. The technology can only be used on OLED panels and this has limited the proliferation of the technology a great deal.
However, that may soon change as Chinese display manufacturer BOE Display Technology has announced that it has successfully developed an optical fingerprint technology-supporting LCD panel and that it plans to start mass producing the panels by the end of this year.
Basically, the current on-screen fingerprint recognition technology in use are either optical or ultrasonic technology and both can only be used on OLED panels. This is because the thickness of OLED panels are not so much as compared to LCD panels. Thus, it is easier for penetration to take place between the finger on the screen and the sensor that has to be under the screen. AMOLED panels are more expensive than LCD, making it difficult to have the fingerprint technology on low-end and mid-range phones. Therefore, this new technology is an important one.

Just last month, Taiwanese display maker AU Optronics had earlier announced a 6-inch full-screen optical embedded fingerprint scanning LTPS display. AUO’s display is the world’s first fingerprint scanning technology that supports optical sensors embedded in LCD screens. The panels come with FHD+ resolution (2304×1080) as well as a sub-pixel resolution of 403PPI.
We may likely start seeing phones with this optical fingerprint supporting display from next year or towards the end of this year. It will be interesting to see how responsive the fingerprint sensors would be.
