First of all: IPS is not a screen material, but a technical name. Its essence is actually superTFT, which means that the IPS screen is also one of the TFT screens!

If you want to say which is better, it is of course the screen with IPS technology is better. The IPS screen changes the arrangement of the TFT liquid crystal molecules (generally, the common TFT liquid crystal molecules are arranged horizontally, while the IPS liquid crystal molecules are arranged vertically), which can make it have a larger viewing angle, press the surface of the screen will no longer have obvious water ripples (this is what we call a hard screen), the color reproduction is better, and the picture is more realistic. These aspects are incomparable with ordinary TFT.

With so many advantages, it will also increase its cost, and the price of IPS LCD screen will definitely be higher than that of ordinary TFT panel. What is the meaning of IPS screen?

IPS (In-PlaneSwitching) technology is a liquid crystal panel technology launched by Hitachi in 2001, commonly known as "SuperTFT". In response to the question of what IPS screen means, the advantages of IPS screen are its fast response speed, high viewing angle, and accurate color reproduction. It is positioned as a high-end product in the LCD panel. Moreover, compared with PVA panels, the dynamic definition of LCD TVs using IPS screens can reach 780 lines. In terms of static definition, high-definition can still be achieved according to the requirements of the 720-line high-definition standard. This panel technology enhances the dynamic display effect of LCD TVs. When we watch sports events and action movies and other fast-moving programs, we can get better picture quality. Compared with other types of panels, the IPS panel is not easy to be deformed by the water pattern by gently scratching it with your hand, so the IPS screen is also known as a hard screen. When you look at the screen carefully, if you see fish-scale pixels facing left, plus a hard screen, then you can be sure that this is an IPS screen.

What are the advantages of IPS screen?

Flat-panel TV manufacturers have all shown some selling points such as "free high-definition color", "smart light", "dynamic high-definition", "full-mode high-definition digital TV-body machine", etc. A round of competition for market share. The wide-viewing angle technology of the PVA model, which is mainly promoted by Samsung, is widely adopted by Japanese and American manufacturers due to its relatively strong production capacity and stable quality control system. Now PVA technology has been widely used in high-end LCD monitors or LCD TVs. The VA panel also belongs to the soft screen category, and a similar watermark effect will appear when you gently stroke it with your hand.

The effect of voltage

The biggest feature of the IPS screen is that its two poles are on the same plane, unlike other liquid crystal mode electrodes that are arranged three-dimensionally on the upper and lower sides. This technology optimizes the arrangement of liquid crystal molecules and adopts a horizontal arrangement. When encountering external pressure, the structure of the molecules will sink slightly downward, but the overall molecules are still horizontal. When it encounters external force, the solidity and stability of the liquid crystal molecular structure of the hard screen will be far better than that of the soft screen! Therefore, it will not produce picture distortion and affect the color of the picture, which can protect the picture effect to the greatest extent. damage. In addition, there is another S-IPS panel which is an improved type of IPS.

Comparison chart

The LCD panel with IPS hard screen technology not only has certain advantages in terms of durability and easy cleaning, but also leads the VA soft screen in terms of functional parameters and performance indicators. Response time has always been a shortcoming of LCD TVs, but with the continuous advancement of LCD technology, the problem of screen trailing of LCD TVs has also been well resolved on IPS panels. The advantage of its short response time enables the IPS screen to display clearer images in dynamic images. In addition, the IPS screen also has a series of performance advantages such as accurate color reproduction and outstanding black expressiveness compared with the VA soft screen.

IPS

According to the test results, technical experts said: IPS hard-screen LCD TV can display dynamic high-definition pictures, especially suitable for the reproduction of moving images, without afterimage and trailing, and is an ideal carrier for watching digital high-definition images ( Especially - some fast-moving pictures, such as races, racing games and action movies). The expert group said that due to the unique horizontal molecular structure of the IPS screen, it is very stable without water arks, shadows and flashes when touched, so it is extremely suitable for touch-enabled TVs and public display devices.
