The causes of flickering streaks on LCD screens involve multiple factors, potentially related to hardware component anomalies, signal transmission issues, or external interference

First, it should be clear that the main type of radiation produced by LCD monitors is low-frequency electromagnetic radiation, and its radiation level is far below international safety standards. Compared with the old cathode ray tube (CRT) monitors, LCDs have much less radiation. Therefore, the impact of LCD devices on the human body is very limited. However, there are ways to reduce the impact of this radiation. In this article, we will explore some effective ways to reduce LCD screen radiation.

Completely eliminating LCD light leakage is difficult (especially against a pure black background, where slight light leakage may occur at the edges). However, through optimized design (such as high-precision shading structures and zoned light control), the use of high-quality materials (such as low-defect light guide plates and high-light-shielding adhesive strips), and rigorous production processes (such as full lamination and precision assembly), light leakage can be significantly reduced. Shenzhen Hongjia Technology has 12 years of industry experience, specializing in the research and development, production and sales of 1.14-inch to 12.1-inch LCD screens and matching touch screens. It has rich experience in dealing with backlight leakage and can meet the demanding requirements of our customers. We can also accept customization.
