Common causes of uneven color on stadium LED screens
There are many reasons for the uneven color of the stadium LED screen, the following are some of the most common causes of LED screen failure:
- Use inferior LED display panel
- The LED screen has illegal operations during the installation process
- 3. Lack of regular LED screen maintenance and maintenance
- 4. The influence of the lighting environment of the gymnasium
Stadium LED screen usually does not have very serious problems, and the manufacturing process and quality control of the existing LED display panel are very good. Sometimes the uneven color of the stadium LED screen is not necessarily caused by a single problem, but may be caused by multiple reasons. In order to let you better understand the professional content in this area, we propose corresponding solutions to the problems that may exist in the above-mentioned four aspects in the following content.
How to Ensure the Color Uniformity of a Stadium LED Screen
Purchasing qualified LED display panel
As long as the overall budget of the stadium audio-visual system integration project does not exceed the budget, try to choose a good-quality LED display panel. Although purchasers want to pursue the highest cost performance, in fact price is often the final factor that determines their purchasing behavior. Galaxyav has more than 20 years of history in the field of LED screen manufacturing and deeply understands the principle that you get what you pay for. Those so-called cost-effective LED display panels are often the most prone to problems.
Quality-qualified LED display panels must pass 100% quality inspection, and the dust and water resistance must reach IP67 water. The failure rate of display pixels of the LED display panel cannot reach 2/10,000, and the service life should not be less than 100,000 hours.
In addition, stadium LED screens are usually used in outdoor environments, so the refresh rate, brightness, viewing angle, white balance, color vividness, etc. of the LED display panel need to be specially tested. Only when all batches pass the test can they be put into use . It is recommended to only use a certain batch of LED display panels, otherwise the color of the entire screen will be uneven due to the difference in light emission of self-illuminating pixels.
Install the stadium LED screen correctly according to the technical guide
Theoretically speaking, it is best for the stadium’s LED screen installation project to be fully responsible for by the audio visual solution provider. But in reality, there will be various reasons why the plan cannot be finally implemented.
The usual mode of operation is that the local project construction party installs the entire LED screen according to the construction plan, but there will be various mistakes in the details during the installation process. At this time, the stadium audio visual solution provider should exclude professionals to supervise the progress of the entire construction project, give professional advice in some technical links, and supervise the smooth installation of the entire project in real time.
Regularly arrange special personnel to overhaul and maintain the LED screen
The LED screen will also have uneven overall color when it encounters various situations such as insufficient rated voltage, electromagnetic signal interference, and solder joints on the circuit board. These problems can only be eliminated one by one by professional technicians, otherwise more and more problems will directly reduce the service life of the entire stadium LED screen. Regular inspection work is very necessary, it allows you to find and deal with the problem at the initial stage, so that the loss is minimized.
Appropriately improve the usage environment of the stadium LED screen
Although there are more and more large gymnasiums, not all gymnasiums have automatic opening and closing domes, because the construction of domes will consume a lot of resources and sufficient technical reserves. A stadium without a dome cannot avoid the interference of sunlight, wind and rain on the LED screen, resulting in uneven color of the LED screen.
Strong direct sunlight causes the LED screen to have to adjust the display brightness to the highest level. These tens of thousands of LED screen light-emitting pixels work at full power, which will soon affect its service life. Most of the self-illuminating pixels have local uneven color display within 3-4 years of overall project use. If conditions permit, it is necessary to properly improve the use environment of the stadium LED screen.
There are many reasons for the uneven color of the Stadium LED screen. The common ones are poor quality LED display panel, unreasonable installation process, no regular inspection and maintenance, and poor external use environment, etc. Galaxyav provides you with corresponding solutions based on more than 20 years of professional experience, hoping to help you solve the problem of how to ensure the color uniformity of the stadium LED screen.
