Recently, at the 2019 International New Display Technology Exhibition, Liu Xiaodong, vice president of BOE, announced that BOE has successfully developed an optical fingerprint recognition technology under the LCD screen and will start mass production of embedded optical sensors at the end of 2019. LCD panels are mainly used in low-end smart phones.

Data shows that the ratio of global full-screen smartphones has soared from 9% in 2017 to 65% in 2018. It is expected to increase to 81% in 2019. By then, the global demand for full-screen smartphones will reach 1.26 billion units. As the demand for full-screen smartphones soars to 1.46 billion units in 2020, the ratio of full-screen smartphones will also increase to 90%, opening the market for the promotion and application of under-screen fingerprint technology.

The advantage of the LCD screen is that it uses a three-color standard arrangement, which is not prone to visual fatigue. The definition of the LCD screen will be higher under the same resolution; but its disadvantage is The light source is provided by the backlight, which cannot display true black, and there will be light leakage from the side. The most important thing is that the fingerprint technology under the screen could not be realized before.

Under-screen fingerprint recognition is generally carried on flagship mobile phones. Few mid-to-low-end phones are equipped with under-screen fingerprints, because fingerprint recognition previously required an OLED screen, which will inevitably increase the cost of mobile phone manufacturing. But now this shortcoming may be solved, and more low-end mobile phones can be equipped with under-screen fingerprint technology!

It is understood that the current price gap between LCD for Samsung panels and LCD panels has narrowed to less than US$5. The rapid growth of LCD for Samsung screen shipments is also constantly eroding the LCD panel market. Some analysts predict that LCD will lose about 30 million pieces of the market this year.

Currently, the fingerprint technology under the LCD screen has not yet entered the commercial stage. After mass production at the end of the year, it will be of great significance to Huawei. Because Huawei has always been a big seller of BOE, and Huawei mobile phones basically use screens produced by BOE. Previously, LCD screens could not achieve under-screen fingerprint technology, which directly led to Huawei’s failure to carry the current popular low-end mobile phones. Fingerprint technology under the screen. Today, BOE's overcoming of this technology will meet the purchase needs of Huawei's mid- and low-end mobile phone users, and these users can buy mobile phones equipped with under-screen fingerprint recognition at a lower price.
