The vivo X23 is the latest model of X-series. In addition to the Qualcomm Snapdragon 670 mobile processor with more advanced 10nm technology, the audio architecture is also upgraded to AKM's latest mobile DAC technology. Thanks to the introduction of icc support, the screen performance of X21 brought us some small surprises. The subsequent NEX also inherits the advantages of icc color management. What color and performance can the X23 screen bring?
The X23 screen still uses the Samsung AMOLED panel. The 6.41-inch color seems to be the same as the Galaxy Note9. However, since the LCD screen has flourished, the screen size is measured by the long side by default, and the X23 screen ratio is already 2.17. 1, in fact, the length and width dimensions are only a few millimeters more than the X21. The screen is cut with rounded edges and top round holes. It is also called ¡°water drop¡±. Foxconn¡¯s Sharp mobile phone has also tried similar screen cutting and layout schemes. The screen to the end of the X23 is also narrower than the X21. The screen-to-body ratio is about 90%. Looking at the mainstream video 16:9 aspect ratio video, there will be no problem, but in the 21:9 that movies and TV shows like, then this type of cutting will affect the screen viewing, of course, more and more game and applications are adapting for widescreen.
X23 screen resolution is 2340x1080 [diagonal], the nominal PPI is 401, due to the AMOLED's diamond-shaped Pentile molecular arrangement, the actual pixel density of the screen is lower, and the sub-pixel gap is larger than the RGB-arranged TFT. The reason for choosing AMOLED are better colors, higher contrast, as well as faster screen response and higher brightness. These features will have a significant impact on the consumer's experience when used intuitively. The under display fingerprint sensor like an optical camera, therefore, with the improvement of resolution and aperture, ISP processing speed and other performance indicators, the recognition rate and speed of the fingerprint under the X23 screen have also improved.
In the X23's FuntouchOS system, vivo has finally added the color temperature adjustment function. From the actual test, the color temperature adjustment and the original eye protection mode have the same effect on the screen color temperature and Gamma, but the adjustment range is somewhat different. It is a common practice to test the objective index of the screen by SpectraCal Calman. If there is no special explanation, it is the test score under the standard dynamic range static image.

In the vivo X21 UD Review: Display we have briefly introduced vivo join icc members of technical significance and user value, X23 color performance remained since the X21 and NEX bring icc characteristics, so color style and color performance are basically the same, this consistency is a mobile phone company concerned about display technology should be achieved and maintained. Of course, the mobile phone is not a professional display device. The grayscale and color accuracy of the X23 are consistent with NEX, while Gamma is slightly higher. The grayscale and color difference indicators of X23 are slightly inferior to the X21. The main problem is that the error of the warm color such as red is obvious. Look carefully at the triangle of the color gamut. The red dot will always be slightly offset from the standard coordinates, but it will not affect the overall visual experience. There is no obvious color dynamic loss. The P3 mode gamut coverage is 103%, and the sRGB mode is the standard 100% sRGB. In the built-in album apps, it has certain reference in color when browsing the sRGB and P3 color gamut images, and the color accuracy in the two different color gamuts is basically the same. The default desktop and third-party applications remain P3 colors. display.
Using Experience: Compared with X21 or NEX, X23 has a higher brightness performance, and its peak brightness exceeds 600cd/m2. It still has good graphic readability under the big sun, and upgrades for X20 and X21. The progress of such a user should be very obvious. In the side view, the screen can still maintain a good color contrast, with a slight red and green alternating color distortion [need to move the phone or line of sight to see, easy to adapt when stationary], low-brightness flicker of X23 is are basically the same with NEX. Using the iPad Pro's high refresh rate screen will appear below 30% brightness. Overall, compared with the X21 or NEX, the significant improvement in brightness of the X23 screen will greatly improve the user's experience in outdoor and other environments, as well as the readability of the screen when taking pictures. Of course, if the manufacturer can correct the performance of the red tone, it will highlight the use value of the color reference.
