Tianma TED FingerPrint (TFP): World’s First Multi-point Fingerprint Recognition LCD Display with 50% Less Thickness
In-screen fingerprint recognition (or under-screen fingerprint recognition) is today’s absolute mainstream solution, but because of the nature of the screen, OLED panels are an excellent partner, while LCD panels are more embarrassing. Fortunately, various panel manufacturers have been seeking breakthroughs.
Today, Tianma officially released the world’s first self-developed LCD screen multi-point fingerprint solution “TED Finger Print”, referred to as TFP, with independent intellectual property rights, high integration, full-screen multi-point fingerprint recognition, high screen-to-body ratio features, and reducing the screen thickness by 50%
It is reported that this solution embeds the fingerprint image collector in the TFT display substrate, and for the first time realizes the integration of the three functions of touch, display, and fingerprint recognition into one, and at the same time covers the entire display screen with the optical path and sensor, and is equipped with a sensor based on the glass substrate, and the size of the sensor is not limited and can realize “full-screen multi-point” fingerprint recognition on the full screen.
Tianma’s multi-point fingerprint solution in the TED FingerPrint (TFP )screen has three core advantages:
First is high integration
For the first time, it realizes the three-in-one combination of touch, display and fingerprint recognition, and breaks through the limitation that the optical fingerprint in the LCD screen is difficult to match the thickness of the normal cover plate. It is more market competitive and mass-producible.
At the same time, because the optical path modulation unit is integrated inside the display screen, the thickness of the display screen is reduced by more than 50% compared to the external collimated optical path design scheme, and the terminal product design is lighter and thinner.
The second is full-screen fingerprint multi-point recognition.
It supports multi-point fingerprint recognition in any display area of the full screen, which can be applied to blind unlocking of the full screen, APP encryption unlocking, and custom fingerprint control, which can bring higher security and privacy.
The third is the high screen ratio
The fingerprint recognition function is built into the display screen, which can effectively increase the screen-to-body ratio of the terminal product.
Although “in-screen” and “under-screen” fingerprint recognition are often mixed, they are strictly different.
The so-called under-screen fingerprint recognition refers to a technology that completes the fingerprint recognition and unlocking process through the bottom of the screen glass, including capacitive, optical, ultrasonic and other categories, but due to technical and cost reasons, most of them can only be used in a fixed area to realizes single-point fingerprint recognition.

The TED FingerPrint (TFP) screen multi-point fingerprint solution released by Tianma this time uses an optical fingerprint recognition mode to integrate the fingerprint image collector into the display screen, which can realize “full-screen multi-point” fingerprint recognition on the full screen, which is better than the fingerprint under the screen. The product has a larger screen recognition area.
Tianma said that this technology will greatly enhance the diversified space of intelligent terminal human-computer interaction experience. For example, it can deepen the APP, protect wealth and safety, and enhance the driving experience of vehicles; it can also be used for smart factories, smart cities, smart homes, and smart transportation. Intelligent medical information security provides a higher level of protection.
At present, Tianma’s multi-point fingerprint technology in the LCD screen is ready for mass production, and it is sending samples to well-known brand terminals around the world and will cooperate with customers promptly to achieve the world’s first terminal models.
