IPS（In-Plane Switching，平面转换）硬屏技术是目前世界上最先进的液晶面板技术。IPS 技术到目前按照原开发商日立的官方说法是发展了四代，第一代是 IPS，又称为 SUPER TFT，第二代称为 S-IPS，第三代称为 AS-IPS，第四代称为 IPS-PRO。每一代历程都来源于晶格的变化，这也是判断日立系 IPS 所属世代的一个办法。
IPS (in plane switching) hard screen technology is the most advanced liquid crystal panel technology in the world. So far, according to the official statement of Hitachi, the original developer, iPS technology has developed for four generations. The first generation is IPS, also known as super TFT, the second generation is S-IPS, the third generation is as-ips, and the fourth generation is ips-pro. Each generation process comes from the change of crystal lattice, which is also a way to judge the generation of Hitachi IPS.
Advantages of IPS hard screen
1. Eliminate visual “dead corner”
IPS 屏幕面板的视角可达到 178 度，正面观看与不同角度观看时所产生的颜色变化程度成为色彩扭曲率，所得的数值几乎用肉眼分辨不出来。意味着从正面还是侧面观看画面的效果是相同的。传统的液晶显示屏，从侧面或者比较偏的角度看，画面会比较模糊，色彩会产生飘逸现象，IPS 技术完美的解决了这一问题。它利用其独特的分子水平转换结构，能够达到上下左右 178 度的超广视角，完美的消除了视觉“死角”。
The visual angle of IPS screen panel can reach 178 degrees, and the color change degree when viewing from the front and from different angles becomes the color distortion rate, which can hardly be distinguished by naked eyes. It means that the effect of viewing the picture from the front or side is the same. The traditional LCD screen, from the side or more partial point of view, the picture will be more fuzzy, color will produce elegant phenomenon, iPS technology perfectly solves this problem. Using its unique molecular level conversion structure, it can achieve a super wide viewing angle of 178 degrees up, down, left and right, and perfectly eliminate the visual “dead angle”.
2. Dynamic picture super clear
IPS 技术的响应技术远远超越传统的液晶显示屏幕，呈现出更加流畅的动态画面。IPS 技术下播放的动态画面图像没有残影、色彩也不会发生偏移现象。这种技术在普通模式下也许表现得差别不是非常明显，一旦播放急速画面时，差别和效果就会很明显的体现出来了。
The response technology of iPS technology is far beyond the traditional LCD screen, showing a more fluent dynamic picture. There is no residual shadow and no color shift in the dynamic image played under iPS technology. This kind of technology may not be very obvious in the ordinary mode. Once the fast screen is played, the difference and effect will be obvious.
3. Energy saving and environmental protection
IPS 屏幕技术在核能结束方面也有重大突破，IPS 屏幕耗电量进一步下降，更为节能环保。并且由于对液晶分子进行了更合理的排列，减少了液晶层厚度，从而改变了液晶屏的透光率，增加了显示效果，也可以让显示面板更薄、更省电。
IPS screen technology has also made a major breakthrough in the end of nuclear energy. The power consumption of IPS screen is further reduced, which is more energy-saving and environmental protection. And because of the more reasonable arrangement of the liquid crystal molecules, the thickness of the liquid crystal layer is reduced, thus the light transmittance of the liquid crystal screen is changed, the display effect is increased, and the display panel is thinner and more power-saving.
4. Not easy to damage
传统的液晶显示屏非常脆弱、容易损坏。传统显示屏只要用手持轻轻一触，就会产生水纹。 IPS 硬屏挤压也不会产生水纹，画质更具稳定性。IPS 硬屏不会像传统的软屏一样，轻易划伤，有一定自我保护的功能。
Traditional LCD is very fragile and easy to damage. Traditional display screen as long as you touch it with a hand, it will produce water lines. IPS hard screen extrusion will not produce water lines, and the image quality is more stable. IPS hard screen is not as easy to scratch as traditional soft screen, and has certain self-protection function.
5. Color is more professional
IPS 技术的调色能力堪称专家级别，许多专业从事设计、色彩方面的专职人员非常推崇 IPS。 IPS 技术在日常生活中有着极为广泛的应用，我们熟悉的 LG 电视、iphone 的手机都是采用这种 IPS 技术的硬屏。印刷和医用显示屏，则几乎完全采用这种技术。所以，IPS 其实早就“入侵”我们的生活中了。
The color matching ability of iPS technology can be called expert level, and many professional design and color professionals highly praise IPS. IPS technology has a very wide range of applications in daily life, we are familiar with LG TV, iPhone mobile phones are using this iPS technology hard screen. Printing and medical displays are almost entirely based on this technology. Therefore, IPS has “invaded” our life for a long time.
Disadvantages of IPS hard screen
由于 IPS 屏幕采用横向液晶分子排列，增加了可视角度的同时却减少了光线的穿透性，为了更好的展示亮色就要增加背光的发光度，所以漏光现象在 IPS 屏幕是极为普遍的，随着屏幕的加大，大面积的边缘漏光问题一直是 IPS 的诟病。
Because IPS screen adopts horizontal liquid crystal molecular arrangement, which increases the viewing angle but reduces the light penetration. In order to better display the bright color, it is necessary to increase the brightness of the backlight. Therefore, light leakage phenomenon is very common in IPS screen. With the increase of screen size, large area edge light leakage problem has been criticized by IPS.
由于 IPS 屏幕无法改善穿透性而提升背光的做法也让它失去了高对比度的竞争优势，一般 IPS 的静态对比度在 2000:1–3000:1 之间。而 AV 屏幕的静态对比度可以轻松达到 5000:1，因此对比度不高，也是其一个不足。
As the IPS screen can not improve the penetrability, the practice of improving the backlight also makes it lose the competitive advantage of high contrast. Generally, the static contrast of IPS is between 2000:1 – 3000:1. The static contrast of AV screen can easily reach 5000:1, so the contrast is not high, which is also a disadvantage.
怎样识别 IPS 硬屏
How to identify IPS hard screen
1、在播放画面时轻触液晶屏幕，若无水纹现象，则可确认为 IPS 硬屏；若出现水纹现象，则可确认为软屏。
1. Touch the LCD screen when playing the picture. If there is no water mark, it can be confirmed as IPS hard screen; If there is water mark, it can be confirmed as soft screen.
2、可使用放大镜，对比液晶分子形状图，全像素鱼鳞状方向朝左即为 IPS 硬屏。
2. You can use a magnifying glass to compare the shape of liquid crystal molecules. The full pixel fish scale direction is to the left, which is the IPS hard screen.
How to distinguish S-IPS, H-IPS and e-IPS
可以通过像素结构来判断，S-IPS 为渔鳞方向向左，H-IPS 和 E-IPS 均为类像条线型。 H-IPS 是 S-IPS 加强版，而 E-IPS 是 AS-IPS 低成本改良版。
It can be judged from the pixel structure that S-IPS is the scale direction to the left, and H-IPS and e-IPS are image like striplines. H-IPS is an enhanced version of S-IPS, while e-IPS is a low-cost improved version of as-ips.
H-IPS & gt; S-IPS> E-IPS
IPS hard screen and soft screen which is good
1、就电视产品来说，IPS 硬屏的画面色彩更优于 VA 软屏，因为它独特的液晶分子排列结构，画面色彩得以完美的展现，同时让画面更加细腻，凸显真实，许多高端领域例如航天、广播电视等都采用了 IPS 硬屏技术研发的产品。
1. As far as TV products are concerned, the picture color of IPS hard screen is better than that of VA soft screen. Because of its unique liquid crystal molecular arrangement structure, the picture color can be perfectly displayed. At the same time, the picture is more delicate and realistic. Many high-end fields, such as aerospace, radio and television, have adopted products developed by IPS hard screen technology.
2、对于追求现代尖端技术的人来说，能够与 3D 电影配套使用的 IPS 硬屏电视也能给他们带来更多不一样的视听体验，画面流畅，无闪无拖，某些使用率 IPS 屏幕的 3D 眼镜环保自然，得到不少科技达人的青睐。
2. For those who pursue modern cutting-edge technology, IPS hard screen TV, which can be used with 3D movies, can also bring them more different audio-visual experience. The picture is smooth, no flash and no drag. Some IPS screen 3D glasses are environmentally friendly and natural, and are favored by many technology experts.
3、从物理性质上来说，IPS 屏幕也更胜一筹。众所周知，不少液晶屏幕只要用手稍稍一点，就会像水纹一样轻轻散开来，而 IPS 硬屏很好地规避了这个问题，它所形成的表面比其他的屏幕更为坚硬，不易划伤。
3. In terms of physical properties, IPS screen is also better. As we all know, many LCD screens will spread like water lines just with a little bit of hand. IPS hard screen can avoid this problem very well. Its surface is harder than other screens and is not easy to scratch.
4、对于一些小型的终端设备例如手机等，由于观看规格的限制，IPS 硬屏技术的优势并不能得到完全的凸显，因此对画面要求一般的人还是可以选择软屏的设备，VA 屏等软屏作为屏幕市场的“经典角色”，对大部分的消费者来说还是能诠释良好的视觉效果的。
4. For some small terminal devices, such as mobile phones, due to the limitation of viewing specifications, the advantages of IPS hard screen technology can not be fully highlighted. Therefore, people who require ordinary pictures can still choose soft screen devices. As the “classic corner” of the screen market, VA screen and other soft screens can still interpret good visual effects for most consumers.
