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.

In the field of small-size TFT screen driver ICs, ST7796 and ILI9488 ICs are often used by customers. Many customers also have questions when choosing ICs. Which IC is more cost-effective and has better performance? Today I will briefly express my views here. If users are making devices that require high refresh rates, such as gaming devices or video playback, ST7796U may be more suitable. ILI9488 may have more advantages in cost or be more flexible in some interfaces.

The LCD screen itself does not emit light, and a backlight needs to be added to the back of the glass for normal display. This involves how to test the surface brightness and backlight uniformity of the LCD screen. The brightness of the LCD screen surface and backlight brightness are measured through BM -7 equipment test, the test is more accurate when the display is powered normally and displays a solid color picture.

In order to meet the increasing number of new orders, Shenzhen Hongjia Technology added a fully automatic TFT screen production equipment to the factory on November 25, 2024, including one-stop feeding such as glass cleaning, COG bonding, FOG bonding, backlight assembly, etc. before production.

Shenzhen Hongjia Technology focuses on 1.14-inch to 10.1-inch displays and matching touch screens. The company has many experienced TFT engineers who can provide customers with solutions to problems, including one-stop technical support before, during and after sales, and assist customers in the smooth mass production of projects. Customers are welcome to email 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).
