LCD Panel Technology Explained

by:Teeho     2020-06-19
There are many different panel technologies used as production of LCDs. They range from budget TN panels for expensive, professional quality S-IPS and S-PVA panels. The average consumer usually has no idea what panel technology working at their LCD. In fact, many power users also unaware, simply because the panel type is rarely listed by the manufacturer of the monitor specs. Many users buy monitors based on price and size. The price in order to be a factor, but ought to still know the advantages and disadvantages of the different LCD panel types and have the ability to identify them before shifting which LCD to buy. IPS Panel Technology S-IPS/H-IPS (In Plane Switching) panels are generally considered the best overall LCD technology for image quality, color accuracy and viewing angles, but it comes at a price. These types of suitable for graphic design and other applications requiring accurate and consistent color reproduction. S-IPS panels deliver best angles for all current LCD technology, with wide viewing angle all the way to 178 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, players should take this into funds. Fast-paced games may suffer from motion blur or ghosting with S-IPS panels that have a response time higher than 8 ms. IPS LCD's is actually adequate stopgap technology till the screen OLED displays are commercially viable. S-IPS panels can be identified buy a little purple hue on blacks when viewed from a wide angle. There are currently few manufacturers using S-IPS panels in comparison whilst other panels types of choices limited and they often have a higher package price. H-IPS is a newer variation of the S-IPS with a second pixel structure, which improves contrast ratio and lowers the pixel pitch to be able to provide better image good quality. VA Panel Technology VA (Vertical Alignment) technology such S-PVA/MVA the middle of the road LCD panels. Supply better color reproduction and wider viewing angles than TN panels, but have slower response times. Usually are very similar to S-IPS on paper. They offer wide viewing angles and good color rendition, even so as good as S-IPS. Response times are generally worse than TN or S-IPS panels, and there has been reports of a few panels that suffer from input lag, so maybe VA technology can end the best choice for fast paced games. VA panels have the advantage of higher contrast ratios when compared with other panel types, which leads to better black levels. Lowered disadvantage of VA panels is color shifting. Color shifting is when bulk seen from one angle changes or 'shifts' when viewed from a slightly different angle, makes various uneven brightness levels through display. This bothers many users to the point that they will not consider buying a VA based panel, while other users will not notice / aren 't bothered by the color fluctuates. Colour change also cause loss of shadow detail in dark scenes when viewed directly from the center. VA panels are much easier to find compared to the IPS, because so many manufacturers use them. They supply you with a better picture quality than TN is cheaper than IPS based panels. TN panel technology Example of viewing angles commonly found with TN-based LCD TFT module . TN (twisted nematic) end up being most common type of panel in the manufacturing of LCDs. TN panels are cheap and offer excellent response times, these perfect for fast paced games. Response times of current TN panels coming from 2ms to 5ms. However, color reproduction, viewing angles and contrast ratios of TN panels are waist of all current LCD panel technology. Unlike most 8-bit IPS / VA panels are TN only 6-bit and unable to show the full 16.7 million colors available in 24-bit true colors. They can mimick the 16.7 million colors of 8-bit panels using a technique called dithering, but the email address details are not impressive. TN panels have become popular the actual use of average computer user since they will be very cheap and currently dominate the China LCD module market availability.
