The Tianma Group introduces true circular 5.0-inch LCD for use in smart home devices

Chino, CA, May 23, 2018 The Tianma Group has developed a true circular 5.0-inch LCD for smart home and high-end medical applications. The full active display features resolution and contrast ratio performance that rivals that of OLED displays. Tianma will demonstrate the true circular 5.0-inch LCD at Display Week 2018.

Tianma developed this true round LCD prototype as the ultimate expression of the freeform display design style, featuring a super-narrow 3mm concentric border and ultra-thin construction (2.1mm).

For backlighting, the module utilizes mini-LED technology for multi-zone local dimming, achieving a dynamic high contrast ratio of more than 1,000,000:1. The high contrast ratio and high resolution of 1080x1080 make this LCD comparable in performance to OLED technology.

The true circular display uses GFF (glass, film, film) capacitive touch, with haptic feedback technology to enhance the unit’s functionality and heighten the user experience.

Tianma expects this prototype to be ready for market by the end of 2019.
