What is e-ips in the liquid crystal display

It is well known that the quality of a liquid crystal display first depends on its panel, because the quality of the panel directly affects the viewing effect of the screen, and the price of the LCD panel to account for the entire display cost more than 70%, is the main factor affecting the cost of LCD, so to choose a good liquid crystal display, first of all to select its panel. At present, the production of LCD panel manufacturers mainly Samsung, LG, friends, and so on, due to the differences in technical level, the production of LCD panels are also roughly divided into different types of machine, Common has TN panels, MVA and PVA, such as VA panels, IPS panels.

And IPs is currently the king of these kinds of LCD panels, IPs (In-plane switching, plane conversion) technology is Hitachi in 2001 launched the LCD panel technology, commonly known as "Super TFT." IPS camp led by Hitachi, gathered together LG, Han Yu Crystal, IDTech (Chimei Mei Electronics and Japan's joint venture company) and other manufacturers, but in the market can not see a lot of models, and although the IPS is developed by Hitachi, but the follow-up research and development efforts Limited, At present we can see in the market IPs panel almost exclusively from LG.

E-ips is a h-ips, Super simplified version of the economic edition. Similarly, E-ips has all the advantages of IPs, and the response is faster and the display works better. has a 178-degree wide viewing angle, no indentation of the panel, color more sharp, image without trailing characteristics. We know that the traditional VA soft screen, whether MVA or PVA, its liquid crystal molecules are vertical distribution structure, compression is easy to deform, and e-ips belong to the hard screen, the use of planar conversion technology, molecular transformation is stable, better quality performance than the VA soft screen.

From the official E-ips technical documentation, we can see that e-ips has more advantages over our more familiar VA wide-angle panels. We often say that VA's visual angle and display effect is better than TN a lot, but compared with e-ips, but it is very different. This is also related to IPS special panel structure, the two poles of the IPS panel are on the same surface, and unlike other liquid crystal mode of the electrodes are in the upper and lower sides, three-dimensional arrangement, so the IPs will not produce drag shadow, and the VA panel drag shadow phenomenon is more serious, and e-ips also with IPs as hard screen, color saturation, The degree of being gorgeous is not equal to the VA.

There is no doubt that the VA panel is a wide-angle panel, but the VA panel is a lot less than IPs for a good degree. At 170 degrees above the angle of view, TN is already a white, but the VA panel is a lot better, but the screen color will fade, or to a certain extent affect the visual effects. And as the most powerful wide-angle panel, E-ips has a true 178 degrees of visual angle, so that you can see in any angle, the perfect picture, which is the IPs leading VA panel a big advantage.
