How To Identify The Quality Of Flexible Led Screen?

The development of full-color LED display in recent years can be said to be brilliant, but more and more scenes have been deployed on it, resulting in the current display effect has long been not as able to give people a strong sense of shock, everyone's requirements for display have become higher and higher, is no longer limited to the conventional flat display modeling, in view of this, Special-shaped LED flexible screen was born, which not only has the characteristics of thin, flexible, folding, but also can achieve stretching, twisting, rotating and other changeable modeling, stretching amplitude can reach 133%, because of these characteristics, special-shaped LED flexible screen can be a more fashionable appearance and more scientific and technological flavor of the shape appeared in everyone's field of view. For example, we can often see LED cylindrical screen, LED ribbon screen, LED wave screen, LED Mobius ring, LED spherical screen, LED hemisphere screen, LED ball screen, LED sleeve ring screen and other products, can use shaped LED flexible screen to splice, as a user of us, how should we identify the quality of LED flexible screen? Identification can be made from the following dimensions:

1. Flatness

The surface flatness of the LED flexible screen is required to be less than 1mm error, in order to ensure that the image will not be distorted when the product is displayed, local convex or concave will lead to the viewing Angle of the full-color LED display dead Angle, flatness is directly related to the manufacturer's production process;

2. White Balance Effect

White balance effect is a very important indicator of LED shaped screen, color science when the red, blue and green three colors of the primary color ratio of 14:60:16 will show pure white, if the actual proportion of a little deviation will appear white balance deviation, generally need to pay attention to whether the white will be blue or yellowish green pure in, The quality of white balance is mainly determined by the control system of the LED shaped screen, and the tube core will also have a certain impact on the reducibility of color;

3, Whether There Are Color Blocks

The color block refers to the obvious color difference between the adjacent modules on the LED flexible screen, and the excessive color block phenomenon caused by the module is mainly caused by the control system crossing and the gray level is not high, and the scanning frequency is too low;

4, Display Brightness And Viewing Angle

As we all know, the display brightness of the full-color LED display used in the indoor scene needs to be above 800cd/㎡, the semi-outdoor scene needs to be above 1500cd/㎡, and the pure outdoor scene needs to have a display brightness of at least 3500-5000cd/㎡ to ensure that the display can obtain a clear display effect. The display brightness of the LED display is directly related to the use of the LED core, the size of the viewing Angle will be directly related to the number of the audience, therefore, the viewing Angle is theoretically the larger the better, the size of the viewing Angle is mainly determined by the packaging of the led core, but the need to find a balance between the display brightness and viewing Angle;

5, Whether There Is A Mosaic And Dead Point Of Imagination

Mosaic refers to the small four squares that are often black or steady on the LED flexible screen, that is, the phenomenon of necrosis occurred in the module, mainly because the quality of the connector used by the LED flexible screen is not up to standard, the dead point is a single point that is always on or often black on the LED flexible screen, and the number of dead points is mainly determined by the quality of the LED concerned;

6. Reducibility Of Color

The reducibility of color mainly refers to the reducibility of the full-color LED flexible screen for the color itself, that is, the color displayed by the LED flexible screen should be kept at a higher level with the color of the playback source, so as to ensure the realism of the image;
