Dynamic clarity
IPS screen technology is currently the world's leading liquid crystal technology. Compared with the traditional screen LCD, the hard screen LCD of the IPS screen technology has a faster response speed and a smoother motion picture. It has the following advantages:
1, dynamic picture, no image afterimage
2, dynamic picture, uniform response speed
3, dynamic picture, color without offset
In order to detect the dynamic definition of the hard screen, it can be seen in the comparison of the gray level of the dynamic image response time of the authoritative test. In the 60Hz picture, the dynamic response speed of the IPS screen liquid crystal is faster than that of the ordinary screen liquid crystal, and the IPS screen liquid crystal The TV shows a balanced "dynamic response time" in all gray levels. When the maximum speed of 120Hz is reached, the dynamic response speed of the hard screen is still faster than that of the soft screen. That is to say, the IPS screen can still express the dynamic picture effect well when playing the fast picture.
Wide viewing angle
The traditional soft-screen LCD TV, when viewed from the side, will cause color drift, resulting in blurred images. Because IPS hard screen has a unique molecular level conversion structure, it can reach a viewing angle of 178 degrees from top to bottom and left and right. The color expression at any angle is not compromised, almost reaching the limit of liquid crystal display technology, basically eliminating visually. The "dead angle". At the same time, there is no color drift like a soft screen, and a clear picture can be seen from the side.
Sturdy screen
There is no residual image when touched, no water grain, the physical structure of IPS hard screen is stable, and the inevitable residual image and flickering phenomenon on the ordinary screen will not appear when touched. The molecular arrangement of the IPS hard screen is horizontal, so the molecular structure is slightly depressed downward when touched, but the whole molecule is still horizontal, and the ordinary screen with the molecules arranged vertically is heavily depressed when touched, the structure is unstable, and after touching the screen The IPS hard screen has a recovery speed of about 10 times faster than a normal screen soft screen.
Professional color
The IPS hard screen is comparable to the coloring ability of color experts and can realistically present images. It is widely used in professional fields such as TV stations and is highly sought after by professionals.
Universal screen
With the development of liquid crystal products, various liquid crystal products currently appearing on the market, televisions, monitors, mobile phones, etc., respectively, adopt IPS hard screen panels, and the color effects exhibited can reach a consistent field.
Size advantage
Due to the difference between the IPS screen and the VA screen in the panel cutting process, the IPS screen is generally 42 å‹ and 47 在 in the mainstream size, while the VA screen is cut in 40 å‹ and 46 ,, 42 å‹ IPS screen. The diagonal length is 106.68 cm, while the 40-inch VA screen diagonal length is 101.6 cm, and the 42-inch IPS screen is 12% larger than the 40-inch VA screen. It is roughly equivalent to the size of a 5†mobile phone screen.
The IPS panel has a greasy feel and is tired. But not everyone's eyes are so sensitive, some people don't feel it. According to GZ users, if it is the mirror screen of the LG IPS panel, it will reduce the greasy feeling through the glass. This is why the Apple monitor uses the LG IPS panel to make the mirror screen.
The IPS screen produced by LGD belongs to the cheap version of the high-end screen and belongs to the worst-case screen.
Don't say that Apple is also used. Apple's IPS and IPS on general monitors and laptops are not on a cost line. Although everyone is called IPS.
I don't know what kind of backlight the IPS screen can be found. If it is LED backlight, it should be a tragedy for the eyes. The earliest use of IPS is DELL. Currently, the version of white LED is not as good as the previous version of the traditional light source.
In fact, the K27's screen is worse, it doesn't matter to me. The notebook has always been used for external monitors and keyboards. Occasionally "moving", very few. Change the price of an IPS screen, add a little, and have been able to start the mainstream 19 to 22 display.
Which of the IPS screens and TN screens is less harmful to the eyes?We all know that there are many factors to consider when purchasing a computer. In addition to the important configuration and price, the screen network dimension is also an extremely important aspect, because more and more people need to work in front of the computer for a long time, for glasses. The damage is not negligible, and currently there are two main types of notebook screens on the mainstream market: one is the TN screen, which belongs to the soft screen, and a similar water pattern appears by hand. The other is the IPS screen, which is called a hard screen, which has the advantages of accurate color reproduction and fast response speed compared to the TN panel.
The difference between TN screen and IPS screen
Knowing it and knowing why, so before discussing and analyzing which eye damage is less between IPS and TN, Zifan still has to discuss with you the difference between TN screen and IPS screen.
The main advantage of the TN screen in the LCD era is that the cost is lower, but the visual effect of viewing from the side is less than that of the TN screen. The viewing angle of the screen of the TN panel is not good. Exit the mainstream market.
From the advantages and disadvantages of the TN panel, the advantages of the TN panel are that the output gray level is small, the liquid crystal molecules have a fast deflection speed, and the response time is easy to be improved. Currently, the liquid crystal products below 6ms on the market basically adopt a TN panel. With the continuous improvement of the TN panel, the latest TN panel display no longer sacrifices image quality due to high-speed response, and the picture quality is close to the simplified version of the wide viewing angle panel display. There is also a big gap in price compared to the wide viewing angle panel.
The IPS screen can be said to be an upgrade of the TN screen. When users enjoy high-speed motion pictures for a long time, the IPS hard screen can ensure clear, smooth and real effects. It has a large viewing angle, accurate color reproduction and low power consumption. Advantage, but the price is more expensive than the TN screen, while the eye irritation is significantly reduced, fully in line with health appeals.
TN screen and IPS screen selection
After talking about the difference, then which of the IPS screen and TN screen is less harmful to the eyes? Let's start here and discuss with you in detail!
In fact, for the IPS screen and TN screen which is less harmful to the eyes, there is no accurate limit and judgment. For the damage of the display screen to the eyes, it is not blind to the difference of the display panel. The mid-to-high end TN display effect is similar to the IPS.
Eye protection is probably related to the following aspects
Backlight type (WLED, RGB-LED, etc.) display effect (gamut, white or color cast)
Usually, if the brightness of the display is too large, it will easily cause visual fatigue. The refresh rate and flicker of the screen are all factors that cause eye damage. For some people, it is wrong to say that “the LCD monitor will not cause any injury to the eyesâ€. Liquid crystal displays are also radiation-free, but they are much smaller than previous CRT monitors. Because it is too small, people don't feel its radiation. In the previous CRT, after two or three hours, I felt my face dry, because of radiation.
So in choosing the display panel type is not too tangled, it is recommended that you give priority to the IPS screen, after all, this will be a trend.
H-K9L (N-BK7) is crystal clear and has excellent transmittance from visible to near infrared (350-2000nm). It is the most commonly used optical glass for the preparation of high-quality optical components. When the additional advantages of UV fused silica are not required (in When the ultraviolet band has good transmittance and low thermal expansion coefficient), H-K9L is generally selected for optical coating and other fields.
The ball lens is a very useful optical element used to improve the signal coupling between the fiber, the transmitter and the detector. In addition, it is also suitable for applications such as endoscopes, barcode scanning, pre-processed materials for Aspheric Lenses and sensors. The ball lens is made of a single glass substrate and can focus or output parallel light, depending on the geometry of the input source. Hemispherical lenses are also very common, and are used interchangeably with (full) spherical lenses when the physical constraints of the application require a more compact design.
