Advanced-MVA is a panel technology developed by AU Optronics, or AUO, a Taiwanese manufacturer of display and screen products. There are many different flatpanel types -- such as TN, IPS and earlier VA lines -- and AMVA was developed to fix some of the deficiencies of the earlier VA and MVA products.
MVA panel can be said to be the earliest wide viewing angle technology. Its liquid crystal layer contains a protrusion for the attachment of liquid crystal molecules. When no voltage is applied, the MVA panel looks no different from the traditional technology. The liquid crystal molecules are perpendicular to the screen. , And once under the action of voltage, the liquid crystal molecules will adhere to the protrusions and shift, forming a state perpendicular to the protrusion surface. This technology effectively improves the response time and viewing angle of the LCD, allowing the viewing angle to reach 170 At the same time, the contrast ratio has also been greatly improved, and the color display capacity has reached 16.7M. Nowadays, this technology is relatively mature, so the market penetration rate is relatively high. Maya's Dabai, Philips' 190P7 and ViewSonic's VX2025wm all use MVA panels.
