LCD Display Key Problem is Solved -- Fingerprint Technology on LCD! LCD display manufacturers
For most mid-to-high-end smartphones, the display fingerprint function has become an indispensable selling point, but consumers must have discovered that the current mobile phones that use display fingerprints basically use AMOLED display, which is for some consumers who are dissatisfied with AMOLED displays. It is inevitable that the person will feel a little unhappy.
Of course, this is a helpless move. According to the feedback from the supply chain, since the LCD display needs to add a backlight layer and the display module is thick as a whole, the display fingerprint technology based on photoelectric technology cannot be applied to the LCD display . Most display fingerprint phones have to be used with AMOLED display .
But for some consumers, the use of PWM dimming on AMOED display at low brightness causes eye discomfort. Although some manufacturers have added DC-like dimming strategies to alleviate this problem, it is not a cure. In addition, AMOLED display have relatively strong color and poor color accuracy, so they are not as good as LCD display in some display competitions.
However, with continuous breakthroughs in the supply chain, the monopoly of AMOLED display on display fingerprints is expected to be broken. According to Internet news, the supply chain manufacturer Fushi Technology announced that it has successfully developed an LCD panel-based display fingerprint solution, and using a neural network deep learning solution, the recognition speed and accuracy are almost the same as capacitive fingerprint recognition.
It stands to reason that LCD display have more advantages in terms of production capacity and cost. If LCD display fingerprint unlocking solutions can be successfully popularized, it will obviously play an important role in reducing the cost of mobile phones. It's just that the current supply chain has not yet mass-produced this plan, and perhaps products equipped with this technology will not be able to meet with us in a short period of time.
Xiaomi's product manager said that he has indeed heard of LCD display fingerprint solutions in the supply chain, but I am afraid that it will not appear on the market within this year. In fact, it often takes a long time for a technology to appear to mature. For example, it took 3 years for display fingerprint technology from its birth to commercial use.
In addition, if only one supplier has developed an LCD display fingerprint solution, there is a high probability that it will not be adopted by other manufacturers, because the manufacturer will have no advantage in bargaining.

In the current field of electronic devices, the lcd display screen is a crucial part of human-machine interaction. However, traditional lcd display solutions often face structural design constraints, limiting their effectiveness in specific scenarios. Against this backdrop, UART lcd displays, which are easier to develop and do not require consideration of underlying display technology, are gradually emerging as the optimal solution to overcome these structural limitations.
