How to judge the good and bad of flexible LED display?
Flexible LED display is a new type of display technology that has developed rapidly in recent years, it has the advantages of lightweight, thin, easy to carry, etc. It can change its shape by bending, folding, stretching, etc., so that it can be adapted to different application scenarios, so that it can satisfy the demand for display of various shapes and sizes, so the flexible LED display in the field of outdoor advertisement, exhibitions, performances, stadiums, etc. has a Therefore, flexible LED display has a wide range of application prospects in outdoor advertising, exhibition, performance, stadiums and other fields. When we buy flexible LED display, it is also very important to learn to judge its good and bad. So do you know how to judgeFlexible LED Displayof good or bad? The following Vishay Technology editorial is for you:
Ways to determine whether a flexible LED display is good or bad:
1. Leveling
The surface flatness of the flexible LED display is required to be no more than 1mm error, to ensure that the product in the display image will not be distorted, and its flatness is directly related to the manufacturer's production process. Otherwise, localized bumps or depressions will lead to dead ends in the viewing angle of the flexible LED display.
2、White balance effect
White balance effect is a very important indicator for flexible LED display. In color science, when the primary color ratio of red, blue and green is 14:60:16, it will show pure white, if there is a little deviation from the actual ratio, there will be white balance deviation. Generally speaking, it is necessary to pay attention to whether the white color will be blue or yellowish green, the white balance is mainly dependent on the control system of the flexible LED display, and the tube core will also have a certain impact on the color reproduction.
3、Color reproduction
Color reproducibility mainly refers to the flexible LED display for the color itself, that is to say, the color displayed by the flexible LED display screen to maintain a high degree of consistency with the color of the playback source, so as to ensure the realism of the image.
4, display brightness and viewing angle
The display brightness of the flexible LED display is directly related to the LED tube core used, and the size of the viewing angle will be directly related to the number of viewers. Therefore, the viewing angle is theoretically the larger the better. Flexible LED display brightness and viewing angle for its application effect and user experience has an important impact, a flexible LED display to meet the requirements should have enough brightness to be clearly visible in a variety of environments, and to provide a large viewing angle, so that the audience no matter from which angle to watch are able to see a clear image. Therefore, only in the case of brightness and viewing angle to meet the requirements, flexible LED display can really play its role in information dissemination, to attract more audience attention.
To summarize, it is the way to judge the good and bad of flexible LED display. In addition, we should also consider the brightness, contrast, encapsulation process, appearance quality, the presence or absence of color blocks, the presence or absence of mosaic, the presence or absence of dead pixels, etc., only a comprehensive consideration of these aspects, a careful view to help us better judge the good and bad of the flexible LED display.
