TN iPS PVA ต่างกันอย่างไร

จอ LCD มีสามประเภทหลัก
1. TN ราคาถูกสุด มีการผลิตออกขายแพร่หลายที่สุด เป็นจอที่พอเห็นทั่วไป เหมาะกับการใช้เล่นเกมส์ เพราะ response time น้อยที่สุด ไม่ค่อยมี ghost เลาเล่นเกมส์เร็วๆหรือดูหนัง ข้อเสียคือสีไม่ตรงจริง สี ไม่ดำสนิท
2. จอ iPS ให้สีสรร เที่ยงตรงสุด แต่ข้อเสียคือแพงมาก ไม่แพร่หลาย หาซื้อยาก หลายยี่ห้อไม่ทำ
3. จอ PVA เจ้าตำหรับคือ Samsung เอามาจาก MVAของยี่ห้อดังเดิม แต่ Samsungเอามาปรับปรุงและทำได้ดีกว่าแพร่หลายกว่า คุณภาพสียังสู้ iPSไม่ได้แต่ราคาถูกกว่าและ response time ตํากว่า iPS จึงอาจใช้ทดแทน TNได้ในการดูหนัง หรือพอเล่นเกมส์ได้

S-IPS Panel Technology

S-IPS panels are generally considered the best overall LCD technology for image quality, color accuracy and viewing angles, but this comes at a price. They are well suited for graphics design and other applications which require accurate and consistent color reproduction. S-IPS panels offer the best viewing angles of any current LCD technology, with wide viewing angles up to 178 degress. VA panels can also have specs as high as 178 degress, but many suffer from a loss of contrast around 165-170 degrees. The response time of S-IPS is adequate, ranging from 6ms to 16ms with current panels. This is only slightly slower than TN panels. However, gamers should take this into consideration. Fast paced games may suffer from motion blur or ghosting with S-IPS panels that have a response time higher than 8ms. S-IPS panels can be identified buy a slight purple hue on blacks when viewed from a wide angle. There are currently few manufacturers using S-IPS panels in comparison to the other panels types making choices limited and they often carry a premium price tag.

Two of the most popular widescreen S-IPS monitors are the NEC 20WMGX2 and Dell 2007WFP. The NEC 20WMGX2 monitor uses an AS-IPS panel (basically a custom S-IPS panel made specifically for NEC), has a 6ms response time, glossy coating and includes a TV tuner and speaker bar. The price of the 20WMGX2 ranges from $500-$600. The Dell 2007WFP is much more affordable at around $350, but you are not guranteed an S-IPS panel and it has less features. Unfortunately Dell uses two panel types in this monitor. S-IPS and S-PVA. It is a completely random process so there is no way to know which panel you will receive. However, due to the much lower price of the 2007WFP many are willing to take the risk for a cheap widescreen S-IPS panel.

VA Panel Technology

S-PVA and MVA panels are middle of the road panels. They offer better color reproduction and wider viewing angles than TN panels, but have slower response times. They are very similar to S-IPS on paper. They also offer large viewing angles and good color reproduction, though not as good as S-IPS. The response times are generally worse than TN or S-IPS panels and there have been reports of a few monitors with VA panels that suffer from input lag, so they may not be the best choice for gaming. S-PVA has the advantage of higher contrast ratios than the other panel types which leads to better black levels. The biggest disadvantage of S-PVA panels is color shifting. Color shifting is when the image from one angle changes or "shifts" when viewed from another angle. This bothers many users to the point they will not even consider buying an S-PVA panel, while others don't even notice the color shifts. Color shifts also cause a loss of shadow detail in dark scenes when viewed directly from the center. Prices on S-PVA panels are around the same or slightly cheaper than S-IPS panels, but they are much easier to find as many manufacturers use S-PVA panels. Also, almost all monitors in the popular 24" category use S-PVA panels.

TN Panel Technology
TN panels are the most widely used panel type as they are cheap and offer excellent response times, making them perfect for fast paced gaming. The response times of current TN panels range from 2ms to 5ms. However, color reproduction, viewing angles and contrast ratios of TN panels are the worst of any LCD panel technology. Unlike most 8-bit S-IPS/S-PVA/MVA panels, TN panels are only 6-bit and unable to display the full 16.7 million colors available in 24-bit true color. They can mimick the 16.7 million colors of 8-bit panels using a technique called dithering, but the results are unimpressive. TN panels have become popular with the average user because they are very inexpensive. They are also the only panels currently being used in 22" widescreen monitors, a very popular size. Many of these 22" TN panels are around the same price or cheaper than other 20" monitors with different panel types, so it is easy to see how how they gained popularity. Afterall, the average user buys a monitor based on price and size
