Abstract

An 8K4K-LCD with the diagonal size of 55 inch has been developed. The backplane is based on an amorphous silicon (a-Si) technology and can operate at 120Hz, which is achieved by developing a technology to compensate the charging voltage of pixels. The realization of a high resolution of 8K4K and a high frame frequency of 120Hz is the world first for LCDs with a-Si backplanes. Moreover, a backlight system with laser light sources expands the color gamut. The newly developed LCD covers 99% of color space defined in BT.2020.

Additionally, we have established three dimensional 8K4K technology. A 3D polarization filter is attached on the 55-in. 8K4K LCD. The vertical viewing angle of 8K-3D LCD prototype is 8.6 degrees at its optimal viewing position set to 1.2m.
