It has been 5 years sence I worked in LED industry. I am getting use to taking photos of the local LED screens at home and abroad. Following I am going to share you these notes along with some pictures that I've met. 

Look at this picture, there are 2 reasons that made such bad screen white balance. The first reason is the screen used different LED lamps,the other reason is poor quality of LEDs. That's why it looks non-uniformity.

Look at the picture below, This is best describled as a mosaic.

Look at the picture below, This following outdoor LED screen is telling you what is "toufu modules".

 Look at the picture below, There is no more good modules in white balance on this LED screen display.

Look at the picture below, feel Trypophobia when seeing this picture regardless of brightness and gray.

Look at the following screen,it can hardly see anything under the sunlight.

Watching this screen, it's 100 percent sure that this display was not made by legal manufcturer. Look at the modules, wires and LEDs,it can see a lot of dark blocks and only used very bad quality raw materials could make this vision.

Below one has badly color unevenness problem, endless color unevenness...

You can see this screen constantly show balck change into white or white to black images. black is white, white is black, Philosophical problems.

This screen is located besides The Chinese Pavilion of Shanghai World Expo, however, I have no idea what is the screen displaying on

Speaking of this one, I thought it was matching by splice technology but not a whole set of display.

 Paying attention to this LED display following, not only is the white balance problems, there is also the problem of the mask.

The following screen are installing in downtown street, but I think no one want to display their advertisements on it.

Look at the following picture, there is no white part out there, the only color we can is red.

The following display was import from other country, but we still can see the wires and dark block.

Did Mr. Wang know about that his company (Dalian Wanda Group）is using such poor quality LED display like this? 

These two projects are made by the same company, you may compare of them.

By the way, do you dare to buy such terrible quality LED screens? Or you are willing to choose Verypixel -- Only Offer Quality LED Displays.
