China 3.0 inch Sunlight-readable display 240*400 MCU Manufacturers, Suppliers, Factory

Some customers are still not very clear about the resolution of the display screen. We will explain it here. The resolution of the LCD screen refers to the number of pixels of the LCD screen, that is, the number of dot matrix, which is usually the number of pixels in the horizontal direction multiplied by the number of pixels in the vertical direction. Under the same LCD screen size, the higher the resolution dot matrix, the clearer and more delicate the display image effect is.

​An LCD display module is an electronic component used for displaying characters, symbols, and graphics in a clear, easy-to-read format. It typically consists of a liquid crystal display (LCD) panel, a driver circuit board, and other supporting components, such as backlighting and a controller chip.

Static electricity can be grounded in the early hardware design. In the later production, pay attention to wearing static bracelets and finger cots to avoid holding the display screen directly with your hands. Then, static electricity experiments can be performed to detect whether the static electricity of the entire machine meets the standards.

Shenzhen Hongjia Technology has successfully mass-produced the 4.45-inch TFT LCD screen, model HJ4450-01. This 4.45-inch horizontal screen LCD features IPS full viewing angle, 1920*1080 resolution, a MIPI interface, and a high refresh rate of 120Hz.

3.99-inch long strip LCD screen with a resolution of 400*960, supporting RGB/MIPI interfaces and featuring a capacitive touchscreen, is currently widely used in the market. Its aspect ratio is well-suited for home appliances, smart home devices, and consumer electronics. The 3.99-inch long strip screen uses common driver ICs, making debugging simple. Another core advantage lies in its unique physical shape and the fine display effect brought by its high resolution.

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.
