P8 P10 Soft Flexible Curved Round cylindrical cylinder Ring Shape LED Display Screen | Manufacturer From China | Enbon

┃ Product Description

Fixed cylindrical series is speciafically use for LED lighting display in various places of the column of lighting and decoration as a whole, the use of no water chest assembly technology, which can achieve any size of the column. The module is also designed with a waterproof groove around the module set and a vent at the bottom to make the product more perfect. The dead zone can satisfy the full 360 degree display of the entire image content. Optional brightness meets different visual demands, a good choice for exhibitions, airports, train stations and indoor or outdoor advertising screens.

┃FAQ

Q : What method do you use to improve luminance and color uniformity?

A:The most important thing is to find out is what your screen manufacturer does to fix the inherent non-uniformity issues found in all LEDs. The method that yields the best results is the PWM correction method, and it often produces a screen that is cheaper than extreme binning methods, because the screen manufacturer does not need to purchase such tight binning lots from the LED manufacturers in order to achieve uniformity. Also, it enables the user to recalibrate the screen as the LEDs become dimmer over the course of several years.

Q: Are correction coefficients used for each pixel or only for each module?
A: For best results, correction coefficients should be provided for each pixel. Correction coefficients for the module can reduce or eliminate the patchwork quilt effect that shows modules with different brightness and color, but it cannot completely remove the boundary differences between different modules and will do nothing to eliminate the dirty window effect caused by pixel-to-pixel uniformity differences

Q: How many correction coefficients are used for each pixel?
A: It is possible to produce correction only for luminance and white point. A screen of this type will use 3x1 correction coefficients (3 coefficients for each pixel). A full color corrected screen will use 3x3 coefficients (9 coefficients for each pixel).

Q: Are the PWM coefficients stored in the modules in addition to storing them in the video controller?
A: The coefficients need to be stored in the video controller in order to perform the video signal processing; however, it is also very convenient to store
