High-end VA class LCD panels are now the widely used type of panel as it has a wide viewing angle panel. This 8b panel can offer 16.7M color panel and its large viewing angles target high-end class panel and have a relative price when compared to the TN panel which is more costly. VA panel can be divided into Fujitsu MVA panel and Samsung PVA panel, the latter serves as a continuation and an improvement. The VA type front panel has the highest contrast though the screen’s uniformity is not that good as the color tends to occur in drift. It has a sharp text that serves as its trump card alongside its high black and white contrast.
Fujitsu MVA technology (Multi-domain Vertical Alignment, multi-quadrant vertical alignment technology) is the earliest wide viewing angle LCD panel technology. Such panels can provide greater viewing angles, typically up to 170 °. AU Optronics panel companies adopted this panel through the Taiwan Province of China’s technology licensing CMO (Chi Mei Optoelectronics). The improved class of P-MVA panel has a nearly horizontal viewing angle of up to 178 ° and its gray response time can be achieved at 8ms or less. MVA is used is some LCD at rest since it is not a traditional tower, but a biased point of rest. When a voltage is applied to the liquid crystal molecules, the backlight level is changed much more quickly through, so that the display room is significantly shortened allowing wider viewing angle as the alignment of liquid crystal molecules changes. MVA was first used as a rapid response panel to conduct propaganda because it has a common LCD response time of up to 50ms or more. It considered a big step forward of history since it is a liquid crystal display that relies on excellent MVA
Taiwan’s Chi Mei Optoelectronics (CMEL), AU Optronics panel enterprises are using this panel technology pursuant to its licensing policy. Taiwan-based panel makers have supported the use of such an LCD display panel market as such TV has been widely used by consumers and it has a cheaper price because many manufacturers produce such technology with large output. After technical improvements, MVA is known as the P-MVA, which retains the MVA panel while the merits of the chip can be used with a variety of booster to achieve a higher response time.
Currently, the MVA panel is considered the most widely used wide-angle LCD panel. Samsung Electronics PVA (Patterned Vertical Alignment) technology also belongs to the VA technology category, which is the successor of MVA technology and developers. Its overall quality has been more superb than the latter. While the S-PVA modified the viewing angles for up to 170 degrees and the P-MVA can go hand in hand with pressurized chip, S-PVA has a response time of up to gray levels and contrast of 700:1.
PVA transparent electrode can get a better opening ratio instead of using the transparent ITO electrode MVA projection of the liquid crystal layer to minimize the waste of backlight. This mode significantly reduces the liquid crystal panel, a “bright” possibility, as the liquid crystal TV era’s position is equivalent to the CRT TV era of the “Long Guan.” Samsung’s main push of the PVA mode wide viewing angle technology, which is attributable to its strong production capacity and stable quality control system, is now widely used by Japanese and U.S. manufacturers. PVA technology is widely used in the current market of high-end liquid crystal display or LCD TVs. VA class panel also consists of soft screen and when gently drawn will appear similar to the waterlines.
Carefully look at the screen roughly like this:
By virtue of Samsung’s powerful panel production capacity, only Samsung’s own production of S-PVA occupies a lot of share in the S-PVA and PVA market due to the absence of licensing requirements.
