What's VA?

VA panel is now a high-end LCD application of more panel types, belonging to the Wide view panel. Compared with the TN panel, 8bit panels can provide 16.7M color and a large visual angle is the type of panel positioning high-end capital, but the price is also relative to the TN panel more expensive. The VA panel can also be divided into the Fujitsu-led MVA panel and the PVA panel developed by Samsung, the latter being inherited and modified by the former. The VA class panel faces the highest contrast, but the uniformity of the screen is not good enough and tends to cause color drift. Sharp text is its killer, black and white contrast is quite high.

Fujitsu's MVA Technology

MVA (multi-domain Vertical alignment, multi-quadrant vertical distribution technology) can be said to be the earliest appearance of the wide view of the LCD panel technology. This type of panel can provide a larger visual angle, usually reaching 170 °. Through the technical authorization, our country Taiwan Province electronic (odd crystal photoelectric), the friend reaches photoelectric and so on panel enterprise all uses this panel technology. The improved P-MVA class panel can reach the near-horizontal 178°, and the gray-scale response time can be up to 8ms.

PVA Technology of Samsung Samsung Electronics

PVA (Patterned Vertical alignment) is also a category of VA technology, and it is the successor and development of MVA technology. Its comprehensive quality has been more than the latter, and the modified S-PVA has been able to keep pace with the P-MVA, gaining a very wide visual angle and faster response time. PVA adopts transparent Ito electrode instead of the liquid crystal layer in MVA, the transparent electrode can obtain better opening rate and minimize the waste of backlight. This model greatly reduces the appearance of the LCD panel "bright spot" the possibility of LCD TV in the era of the status of the same as the CRT TV era of "Dragon tube." Samsung main push of PVA mode wide-angle technology, due to its strong capacity and stable quality control system, by the Japanese and American manufacturers widely used. At present, PVA technology is widely used in high-end liquid crystal display or LCD TV. VA class panel is a soft screen, with the hand lightly strokes will appear similar to the watermark.
