Ordinary LCD screens use CCFL light sources, that is, cold-cathode fluorescent lamps (similar to the scanning lamps in the copy), with one on each side of the screen and a backlight on the back of the display, which is composed of fluorescent substances. The light sources on both sides can be evenly distributed on the back of the entire screen, so that the entire screen can be evenly illuminated. However, due to technical limitations, the brightness of such a display is not completely uniform, but it is difficult to find it. At the same time, the lamp also has a certain lifespan, and it will turn yellow after a long time.

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.

TFT-LCD liquid crystal displays or LCD monitors have become a popular choice for a wide range of applications. However, LCD monitors can be divided into two categories: industrial and consumer. While both types of monitors offer excellent display quality, their designs differ. Industrial LCD monitors are often deployed in places such as factories, outdoor kiosks, digital signage, military and naval applications, food processing, and hospitals. On the other hand, consumer monitors are usually used in office and home environments.

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.

why TN LCD screens are brighter than IPS LCD screens when using the same backlight brightness. Today, engineers from Shenzhen Hongjia Technology will explain this. First, TN (Twisted Nematic) and IPS (In-Plane Switching) LCD glasses have fundamental differences in transmittance, which directly leads to differences in their display effects (such as contrast, color, and viewing angle).
