VA panels are mostly used in high-end LCD products and belong to wide viewing angle panels. Compared with the TN panel, the 8bit panel can provide 16.7M color and large viewing angle is the high-end capital of this kind of panel positioning, but the price is also more expensive than the TN panel. VA class panels can be further divided into MVA panels dominated by Fujitsu and PVA panels developed by Samsung, the latter being the inheritance and improvement of the former. The front (front view) of the VA panel has the highest contrast, but the uniformity of the screen is not good enough, and color drift tends to occur. But because of this, VA panels can be quite effective when displaying black and white text.
Fujitsu MVA Technology
(Multi-domain Vertical Alignment, multi-domain vertical alignment technology) can be said to be the earliest emerging wide viewing angle LCD panel technology. This type of panel can provide a larger viewing angle, usually up to 170°. The improved viewing angle of the P-MVA panel can reach a nearly horizontal 178°, and the gray-scale response time can reach 8ms or less.
Samsung Samsung Electronics PVA Technology
(Patterned Vertical Alignment) also belongs to the category of VA technology. It is the successor and developer of MVA technology. Its comprehensive quality has already surpassed the latter, and the improved S-PVA has been able to keep pace with the P-MVA, gaining an extremely wide viewing angle and faster and faster response time. PVA uses a transparent ITO electrode instead of the protrusions of the liquid crystal layer in the MVA, and the transparent electrode can obtain a better aperture ratio and minimize the waste of the backlight source. In addition, Samsung’s PVA-mode wide-angle technology is widely adopted by Japanese and American manufacturers due to its strong production capacity and stable quality control system. Currently PVA technology is widely used in high-end liquid crystal displays or LCD TVs.
