Excellent signal transmission: tesa 6070x supports high-precision integration of OLED fingerprint film locks

Today, in the pursuit of "ultimate screen-to-body ratio" and "thin and light aesthetics," display technology is undergoing unprecedented changes. As a core link to improve user interaction experience, ultrasonic fingerprint recognition technology has become a standard feature of high-end flagship mobile phones and smart terminals due to its advantages such as strong penetration, unlockability with wet hands, and high security.

However, for display manufacturers and terminal equipment engineers, how to ensure the firm fixation of the fingerprint film lock module and achieve precise signal transmission in the continuously compressed internal space? This is undoubtedly an extreme challenge about "a small area".

The "new pain points" brought about by increased integration

As the design of mobile terminals develops in the direction of thinner, lighter and more integrated devices, the structure of fingerprint film locks becomes increasingly compact.

In practical applications, engineers often face the following thorny problems:

Fixed area reduction

The area and space left for fingerprint film locks to be fixed is getting smaller and smaller. How to maintain high-strength and reliable fixation in a small size to cope with long-term and high-frequency use pressure?

Signal loss anxiety

Ultrasonic fingerprint recognition is extremely sensitive to signal transmission. If the impedance of ordinary adhesive materials is unstable, it can easily lead to a decrease in sensitivity.

Harsh environmental test

Accidental collisions, UV aging and daily waterproofing requirements require fixing solutions to have excellent impact resistance, weather resistance and waterproofing.

Flatness Challenge

In module integration such as OLED, tiny thickness unevenness or surface bubbles will affect the final display effect and recognition accuracy.

tesa® 6070x series

Born for high-quality signal transmission

In response to the above pain points, tesa has launched a targeted conductive bonding solution for ultrasonic fingerprint film lock bonding applications - tesa® 6070x tape series.

Innovative design, flat, stable and aesthetic

This series adopts a unique product design, using copper foil as the base material, and cleverly applying two different acrylic adhesives, black and transparent, on both sides of the base material.

Black side: ensures consistent appearance and prevents light leakage or visual interference.

Transparent surface: Provides excellent bonding performance to ensure that components are firmly fixed.

Excellent performance, enabling high-quality integration

Excellent signal transmission:

Specifically designed for FPC and display modules, it performs well in signal transmission and ensures stable ultrasonic fingerprint sensing performance.

Excellent reliability:

It still has high stability even in a small space, providing reliable fixation for the module without fear of daily impact and high-frequency use.

High flatness and customization:

It has good flatness, and the thickness can be accurately controlled and customized according to the different design requirements of the terminal OLED display.
