Dead pixels?
A dead pixel is an individual pixel on a display panel that is not functioning properly and is always off, locked to a specific color, or has a lamp that has fallen off the PCB. This causes small black dots or certain colors to remain on the screen.
Dead pixels are a big source of screen quality degradation, especially on high-resolution displays, where they are more noticeable and can break immersion. Once noticed, dead pixels get on your nerves and interrupt your viewing experience.
Causes of dead pixels
Dead pixels can be caused by defects in the display manufacturing process, thermal damage from prolonged use, or electromagnetic interference. But the biggest culprit is physical damage.
Strong impacts or pressure can damage certain pixels. This is why surface durability is important for LED screens.
Minimize the incidence of dead pixels
High-quality display manufacturers, like Impact, are doing a lot to minimize these issues.
We conduct TQL testing for strict quality control to ensure product quality. We also apply our own technologies such as cable-free, low-power, Flip-chip, and Simpleboard to ensure overwhelmingly low heat generation.
And a high-quality double coating that provides high surface durability to minimize physical damage, DualCoattechnologies and apply them to our products. We maximize the durability, image quality, maintenance efficiency, and the ability to adapt to the environment in which they are used.
