China 5.5 inch lcd display module 720*1280 Manufacturers, Suppliers, Factory

Usually, touchable LCD screens are capacitive screens, and the positioning method of the touch screen is through the electric field. Therefore, when static electricity and discharge occur, the LCD touch screen will have a "drift" screen effect, that is, the click position is offset from the actual response position.

Small and medium size LCD screen IC supplier

This 5.5-inch INCELL LCD screen can be used in consumer electronics, smart home devices, beauty devices, home appliances, industrial equipment, and other products. Shenzhen Hongjia Technology also accepts custom orders.

In short, for small-sized LCD screens, QSPI is a better choice: through pin multiplexing and queue mechanism, while maintaining sufficient transmission rate, PCB design and master control resource usage are greatly simplified, which is especially suitable for scenarios that require dynamic display and limited space. SPI is only applicable to extreme cases where the driver IC does not support QSPI or has extremely simple functions. When actually selecting, it is necessary to first confirm the interface specifications of the screen driver IC (some screens support both SPI and QSPI, which can be switched by configuring pins).

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.

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
