Lehman officially launched the world's first PM-driven glass-based Micro LED display, with a 220inch screen on display for the first time.

CTOnews.com October 27 news, Lehman announced today, officially released the world's first PM drive glass based Micro LED display, and for the first time exhibited the application of PM drive glass substrate 220-inch Lehman Micro LED ultra-high definition home giant screen.

CTOnews.com organizes Lehman PM driver glass-based Micro LED display as follows:

LEHMAN's first PM-driven glass-based Micro LED display adopts LEHMAN's patented latest COB packaging technology, and at the same time, it uses PM driver to realize image display, which can greatly reduce manufacturing cost while realizing finer picture details; using LEHMAN's unique latest COB packaging technology, combined with the latest glass substrate based on semiconductor, lithography and advanced copper technology, ultra-fine circuit design structure can be obtained on a large area.

The 220-inch Lehman ultra-high definition home giant screen with PM-driven glass-based Micro LED display has a resolution of 3840*2160, brightness of 600nits, viewing angle of more than 170°, color gamut of 90% DCI-P3, and screen display surface protection level of IP65.

According to the official, compared with the traditional PCB board, the core material of the glass substrate and the LED light-emitting chip are inorganic semiconductor crystals, and the two are closer in thermal deformation coefficient; The glass substrate has high thermal conductivity, can better dissipate heat, has the characteristics of low thermal expansion coefficient and low temperature impact resistance, thereby improving the picture performance quality and the service life of the screen, and can also meet the requirements of more complex wiring and higher electrical connection density, thereby meeting the display requirements of smaller size and higher resolution.
