How to solve the electromagnetic interference problem of small and medium size touch screen

First of all, the advantage of incell LCD screens is that they are thinner and lighter than traditional TFT displays because they integrate the touch sensor and display layer into a single layer. Traditional TFT LCD screens require external mounting to fit the touch screen, which increases the thickness. In addition, the touch screen also requires a separate design of a cable, which will occupy the space inside the machine. Incell LCD screens only need to be attached to a layer of glass cover to form a complete LCD touch screen assembly, which makes them ideal for portable devices such as smartphones and tablets. The reduction in thickness and weight makes the design more compact and stylish, which is very important for the trend of thinner and more portable devices.

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

LCD screen leakage typically refers to the leakage of liquid/gel-like substances such as liquid crystal material or sealant from within the screen due to external forces or inherent material defects. Common symptoms include abnormal patches (such as black spots, white spots, or lines) or localized malfunctions in the display area. Lightly pressing the edge of the screen can cause a sensation of liquid flowing, which is common in LCD (liquid crystal display) screens

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. Customers are welcome to email us for consultation.
