TFT screen, I believe everyone is familiar with it. But when it comes to IPS screens, many friends are still relatively unfamiliar. Recently, many friends who have just entered the industry have asked Top One Tech, how is the IPS screen? What are the advantages and disadvantages of the IPS screen? Today, Top One Tech will introduce you in detail!

First,what is an IPS screen

The full name of IPS screen is In-Plane Switching, which means plane switching screen technology. It is a liquid crystal panel technology launched by Hitachi in 2001. It is commonly known as "Super TFT". Compared with the ordinary LCD screen, the dynamic display effect of the IPS screen is clearer and more delicate, and the visual effect is better. It is a relatively high-end product in the LCD panel. At present, it has been widely used in display panels such as touch monitors and mobile phone screens.

Second, the advantages of IPS screen

1. Large viewing angle

The large viewing angle is a prominent feature of the IPS screen. The viewing angle can reach 178 degrees. It can be said to be a full-view screen. Whether it is viewed from the front or the side, the display effect of the screen is the same, ordinary screens cannot achieve this viewing angle effect, so IPS screens are more advanced LCD technology.

2. Size advantage

Compared with the old LCD screen, the size advantage of the IPS screen is very obvious. The screen monitor is larger, the user experience is better, and the original screen defect is greatly reduced.

3. Fast response

Since the liquid crystal molecules of the IPS screen are arranged horizontally and laterally, compared with other arrangements, the horizontal conversion can greatly improve the deflection speed of the liquid crystal molecules, which can greatly improve the response speed of the screen, and the speed is faster and more stable. Especially when watching high-speed moving pictures, the advantages of IPS screen are very obvious, the response speed is faster, the movement trajectory of the image is more delicate and clear, the picture effect is more real and smooth, and the irritation to the user's eyes, image smear and jitter are greatly reduced.

4. True colors

Because the IPS screen has very good color inversion and brightness conversion performance, the color display effect is more realistic. No matter which angle the user views from, the picture effect presented by the IPS screen is the same. You can see saturated and natural ideal picture, so that the advantages of IPS screen color fidelity are perfectly displayed.

5. Color is accurate

The color of the IPS screen is very accurate, so it is favored by many industries. IPS hard screen technology is very high in color saturation and restoration accuracy, so it can meet the needs of design, printing, aerospace and other industries. The IPS screen has a high contrast ratio, a very clear black level, and the color error between the design and the final sample is very small, so it is welcomed by people in the design field. The black contrast effect of the IPS screen is obvious, which is conducive to improving the speed and accuracy of diagnosis in the medical field, so it is also welcomed by the medical industry. All in all, the IPS panel has better consistency and more details, and is suitable for ultra-high grayscale and fine display requirements.

6, the picture is excellent

When users enjoy high-speed moving pictures, the LCD TV with IPS screen can present high-definition dynamic picture display, which is especially suitable for moving image reproduction, and there will be no afterimage and trailing phenomenon, so it is especially suitable for watching digital high-definition images, especially fast-moving footage such as races, racing games, and action movies.

7. Touch without water marks

Compared with other types of panels, the IPS screen is also called a hard screen, and the liquid crystal molecules of the hard screen are more sturdy and stable than the soft screen in terms of structure, so the IPS screen will not appear watermarks when touched by hand, and will not deform. So when Jobs saw the technical advantages of IPS screens, he used them as touch screens. Due to the unique horizontal molecular structure of the IPS hard screen, it is very stable without water lines, shadows and flashes when it is touched, so it is widely used in touch-enabled TVs and public display devices.

8. Environmental protection and electricity saving

Because the liquid crystal molecules of the IPS screen are arranged horizontally, the thickness of the liquid crystal layer is greatly reduced, and the IPS screen uses bipolar driving technology to increase the pixel aperture ratio by 25%, thereby greatly increasing the light transmittance of the liquid crystal screen and reducing the power of backlight,by which can achieve the effect of energy saving. Therefore, IPS hard screen technology is a major technological breakthrough in energy saving technology. Under normal circumstances, the service life of IPS screen is more than 70,000 hours.
