Sharp introduces innovative new technology "UV 2 A technology" leading to 3D TV

Sharp has developed the world's first photo alignment technology "UV 2 A technology" to improve the contrast and response speed of liquid crystal panels.

This technology is said to be a technology leading to next-generation 3D television, and it is planned to be adopted entirely at the Sakai new factory that will be operating from October.

Details are from the following.
Introduced production of the core technology "UV2A (Ubuyueei) technology" of next-generation liquid crystal panel for television | News Release: Sharp

According to this release, Sharp has developed a photo alignment technology "UV 2 A technology" that adopts a special material that reacts by ultraviolet light as an alignment film and precisely controls the alignment of liquid crystal molecules according to the irradiation direction.

By using UV2A technology, it becomes possible to tilt liquid crystal molecules of 2 nano (1 billionth of a meter) with accuracy of pico (1 trillion parts per meter) scale. By using this as the alignment film of the liquid crystal panel, it is possible to display the black sinking without light leakage from the backlight. Also, since the aperture ratio becomes large, it becomes possible to use backlight light more efficiently, so that it is possible to achieve energy saving while displaying vivid colors. It is regarded as the optimum technique for enhancing the performance of high definition 4k 2k display and 3D television expected as a next generation television.

The characteristics of UV2A are summarized as follows.

■ High contrast "5000: 1" displaying "submerged black" (1.6 times compared to conventional)

■ High light utilization efficiency that realizes overwhelming energy saving (aperture ratio: over 20% upward)

■ High-speed response (up to 2 times faster than before)

■ Improvement of production efficiency by simplifying panel structure

This is a brief description of the outline of UV2A technology


Sharp is going to fully introduce the panel adopting this UV 2 A technology to the production lines of the Sakai new factory and the Kameyama No. 2 plant.
