LCD Bonding

LCD & Flat Panel Display

Example images revealing pressure distribution

Pressurex® is a thin flexible mylar film that reveals pressure distribution and magnitude between any two contacting surfaces. Pressurex® indicates precisely how flat panel displays surfaces deform and engage under stress and is useful in the design and quality control process. The spatial resolution is fine enough to expose minute surface defects, patterns and other imperfections as well as detecting lower / higher pressure areas of contact to improve the set up, calibration, materials and bonding process.

Upon the application of force the microcapsules rupture, producing an instantaneous and permanent color change. Like Litmus paper, the color intensity of Pressurex® is quantifiable; the color intensity reveals precisely what pressure level (PSI or kg/cm²) was applied at any discrete point on the surface of the film.
