Be careful!Before buying a monitor, you must understand the certified cat's greasy for manufacturers

Yesterday, the little lion introduced the mysteries of interface standards during the display of display advertising. Today, we continue to scratch the subtext in the speech -the refresh rate synchronization and color certification. There are more and more display "certification". The purpose of certification is to clarify what function you have on a certain product, but now they bring "confusion" but more and more ...

Color authentication: certification is wide and strict, and the purchase of the machine must be strict

Color has become the focus of consumers to buy monitors. Not only the designers and video creators have higher and higher coverage of color accuracy and coverage. Players and audio -visual enthusiasts start from enjoying a more realistic gaming environment and the large -scale movie -level large -scale effects. They also require more accurate color performance Essence Passing professional color authentication is the best evidence and endorsement of the display of the display.

In the field of display, there are many certifications related to color, such as TUV (yes, which is the blue light authentication that) COLOR Accuracy series certification, and the Calman color certification under the support of the famous Portrait, the Technicolor color certification, covering printing There are PANTONE color authentication blessed by X-Rite, a school color instrument factory. But here, the water is not shallow. Because in this field, several certification standards are "wide and strict", and there are standard "water" beyond your imagination!

TUV: Everyone asked me to make a blue light ...

In 2015, Tüv, Germany, launched the TUV Color Accuration certification, requiring the presence of the presence of SRGB and Adobe RGB, the color stability, brightness and uniformity of the display when using it. Excitation, etc.

The four products of EZIO, the large factory of the CRT Long Tube, were the first batch of certification. However, it may be that TUV's Blu -ray eye protection certification is too dazzling. After so many years, most manufacturers are looking for TUV for authentication. It is mainly to make Blu -ray eye protection. The TUV color authentication display on the market can be said to be very small.

Technicolor: Deltae tolerance is amazing

Another well -known authentication is the Technicolor under the support of Portrait Display technical support for display equipment color technology research institutions. Many TVs and monitors have also claimed to pass its certification.

Technicolor certified press release stated: "Although high -end devices continue to bring more motivation and speed, the accuracy and consistency of colors are sometimes despised. Experience. Color is the key to ensuring that users get the best online viewing experience ... "Through Technicolor color certification, the display complies with the same strict standards used by Hollywood and the entire media and entertainment ..." Although Technicolor It has not been disclosed to the specific standards, but some information on a color technology website revealed the relevant standards of Portrait. Not much to say, look at the picture, pay special attention to the red circle part:

Although a quantitative color gamut accuracy coordinate system and GAMMA have been formulated, it seems strict, but suddenly a "acceptable change (error) <7 7 delta E" ... Deltae less than 7! We know that in general, the color of the display is accurate, and the Deltae value is less than equal to 3 to be excellent. But this error actually allows Deltae with less than 7!

BenQ professional display PD2705U paper outlet out -of -the -factor school color report, it can be seen that its Gamma and color temperature curve are smooth and stable, and Deltae is less than 3

In other words, a display that has passed this authentication, if it is strictly obtained in its strict quantitative color standard coordinate system, it is indeed an excellent display. But if it is passed within the scope of "acceptable <7 7 delta E error", it may not be available with "color precision". At least the little lion thinks that its quality control is afraid of a problem, it is actually so in this way, it is actually like this, it is actually like this, it is actually like this, and it is actually like this. Specifies within the scope of large errors. For consumers, the biggest problem is that you don't know what the authentication of this product is, and the manufacturer may not be clearly told you.

Calman certification: three levels, you need to distinguish

Calman is the name of the well -known school color software product of Portrait Display, a display color technology research institution. The agency has decades of experience in serving film and television, radio and television, and display industries. Its school color products are widely used in Hollywood, which can be said to be one of the leading companies in color industry software.

Therefore, its color authentication is named after Calman. Calman certification uses Calman software to evaluate whether the display meets the standard. The certification evaluation color temperature, gamma curve, and Delta E, the standard is that the dletae value between the test data of 19 colors and the reference color is less than 2.

In the process of certification, Calman will display the currently measured color blocks and reference color blocks, and also marked the color coordinates of the measured value, as shown in the figure below. The upper side of each color block is the data read by the caliber. Below is the reference data. After the measurement of each color block is measured, the measurement results of the corresponding color block will appear on the Deltae 2000 results chart. As shown on the left side of the figure below, the CIE 1976 U'V 'Figure appears on the screen, as shown in the right of the figure below -that is, that means It is said that its school color itself is under the color gamut standard to cover the color requirements of multi -scenes.

Then compare whether the Calman Eyeglass has a display to calibrate the correction effect of LUT.

Calman also verifies the degree of illuminance, Deltae maximum value, Deltae average, gamma and related color temperature. The test results show that in a color chart, the result is used to indicate whether the result is passed or not passed the test. Deltae values ​​of different colors are displayed in the column diagram. The figure below is a comparison of the display (above) and the display of not certification (below).

This authentication will test the actual location of 19 test points in the CIE1931 color map, and obtain as accurate color gamut coverage points as possible.

The Calman certification also provides the results of the color gamma curve detection.

It can be seen that this certification is still very rigorous.

But it also divides three levels: Calman Verify, Ready, Powered. When choosing a product certified by Calman, you must also understand whether the specific level of school color standards meets your needs.

Calman Verify: The school color result is used to use

The information provided by this certification standard is: the display has used Calman technology and products for measurement and verification. Consumers who purchase this level Calman certified product can be convinced that their equipment is performed in accordance with the intention of the manufacturer and reached the highest level of color accuracy. The ASUS project display introduced in the last article, and many products of Benq's PD series, and some laptops of MSI are all representatives of this level.

Calman Ready: Frequent colors to meet the diverse colors

The Calman Ready certification level display and device can communicate and connect directly with the Calman color calibration software, using Calman's fast, accurate school color, and automated functions in many cases.

Therefore, the advantage of this certified display is that traditional color calibration is time -consuming, especially when calibrating multi -display. The Calman Ready certified display, through direct connection with the Calman school color software, can achieve rapid automation custom colors in multiple scenarios. Therefore, it is suitable for professional designers and corporate users who need to quickly convert the fields and scenes.

Benq's 4K design professional display PD2705U, PD3205U is the representative product of the Calman Ready certification level

Calman PowerEd: higher integration, increased cost increase

这个认证的产品将Calman色彩引擎直接集成到显示器或设备中，简单来说就是认证机构协助将色彩校准所需的所有组件直接集成到显示器或设备中，进一步简化校准过程，并提供附加功能，创造Personalized viewing experience. For example, a Dell's color meter integrates Calman through a authentication display. However, due to the increase in costs, there are not many display products that have passed this certification.

In summary, ordinary users can choose products that have been certified by Calman Verify. Enterprise users can choose Calman Ready to adapt to a more complex application environment, while more professional single design elites can consider the Calman PowerEd -level certification product. The price of each certification level is increasing, so it needs to be tailored according to demand.

Pantone Caitong (Pan Tong) Certification: Old -fashioned professional history

Pantone Caitong (Pan Tong) was the earliest US printing company and later provided standard chromatography for the printing industry. In the 1960s, a well -known PMS Pan Tong color matching system provided as many as 500 standard color scheme cards. The authority of the printing industry, of course, before the IT era, is the most authoritative color professional technology enterprise. Later, it began to provide color technology services for the film and television, television, and IT industries, until it was acquired by the famous school chromatographic manufacturer X-Rite. To this day, Pan Tong PMS color library has been from 500 standard colors in 1963 to more than 10,000 standard colors. The release of the new version of the "Pan Tong color" library every year is still an important concern in the design world.

Therefore, its color -related certification authority is no problem.

How is Pan Tong certification measured by the display? This authentication mainly tests the ability of Pan Tong's color library to accurately reproduce the standard color of the color library, that is, the ability to reproduce the industry's standard color. Only those displays that can reproduce a certain percentage of Pan Tong can be verified. The test involves thousands of colors of Pan Tong's color library.

In the laboratory environment, the instrument that can be tested by the thick Pan style chromatography (in the school color box in the picture) can be completed in order to pass the Pan Tong certification. In addition to the comparison printing chromatography in the school color box, it will also use the industry authority in the laboratory environment. The X-Rite school color meter is measured for color temperature.

Pan Tong certified the most advanced X-Rite school color instrument of the parent company

The certification even uses Pan Tong's instrument to measure the actual color spectrum information of the display, and the quantification accuracy is amazing.

A Pan Tong certified result table, in addition to the common curves such as color temperature, GAMMA, it can be seen that there are many test colors (in the upper right corner), and the chromatography control coverage (bottom)

It can be seen that Pan Tong certification is already a very powerful display in terms of color accuracy.

But there is another certification level, Pantone Skintone, what does it mean? This certification is more targeted at business and professional photography, medical care, and film and television industries. In simple terms, Pan Tong released a Pantone Skintone certification guide, the first science system for matching and reproduction of human skin color. Including 110 discrete skin tone standards, the actual measurement results of the skin from thousands of people from different races and ages. As a extension of Pan Tong's certification, Pantone Skintone certification guarantees to professionals in industries such as movies, portrait photography, medical anatomy, beauty and beauty, that the certified device not only meets Pan Tong certification, but also accurately reproduces lifelike skin tone.

At present, there are also many designer displays that have passed Pan Tong's certification. Benq and other manufacturers have many products for users to choose from. However, there are relatively few certifications through Pantone Skintone, and the BenQ professional design display 05U series is the world's first professional display that has passed the certification. Dual Pantone certification means more professional color performance, of course, the price is slightly higher than the single certification.

Panjie color card Shanghai Laboratory. At present, the 27-inch entry level passes the display of Pan Tong School for more than 3,000 yuan (such as BenQ PD2705Q). If it is 24-25 inches, it is cheaper. Designer friends may wish to consider

Therefore, for ordinary consumers, choosing the original color effect of the producer of the material producer through Pan Tong's identity can maximize the use of the color.

For people in the industry of medical, photography, film and television, beauty and beauty, then a display that has been certified by Pantone Skintone is even better -they perfectly reproduce the skin color of real people in the real world.

How to choose color authentication?

The answer is simple, according to your specific needs. The budget required for too high certification (for example, ordinary consumers do not need to use Calman Powered). However, the little lion here recommends that it is better to choose more certified products. Because this means that it is recognized in different laboratory environment, different measurement and evaluation and certification standards. Cross -certification is consistent, and it can also effectively screen some products that pass the "water" standard.

What do you need to pay attention to when you have certification?

Certification is easy to maintain. Due to the complexity and professionalism of color authentication, how to maintain the actual performance of the product with the level of certification performance standards requires attention when buying.

For example, some have only one mode through the authentication display. For example, SRGB has passed a color certification, but it does not provide the function of how users can easily adjust the display of the original color accuracy level in other colors and temperature modes. - Users still need to use professional instruments and other help. Or due to environmental light and other reasons, the color brightness performance of the display is unevenly affecting the original color performance.

And some big brands such as BenQ through technologies such as AQCOLOR, Color Consistetency, Uniformity Technology, etc., in use, the uniformity of brightness and color performance in the use ensure the consistency between different screens; or ensure that after long -term adjustment, simple Operation can restore color consistency. These are additional factor that consumers can consider.

Color consistency technology (below) can ensure the color accuracy used in each display, which is especially important for corporate users

What do you want to say or ask for the display of the display? In the future, we will continue to bring you a series of display lines of display advertisements. Welcome to continue to pay attention!
