China 3.92 inch Square tft touch screen SPI Manufacturers, Suppliers, Factory

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.

mainly reflected in high-speed transmission, simplified wiring, low power consumption, high compatibility and other aspects. The following is a detailed analysis of its "advantages" from the perspective of technical principles and practical applications

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.

Generally speaking, the main reasons may include: reducing the number of pins to accommodate a small package size; reducing the need for host control resources (GPIO, parallel interface); simplifying hardware design (PCB layout, level conversion); the small amount of initial configuration data, which is sufficient and easy to implement with SPI; and the driver IC design supporting serial interface configuration.

The 2.0-inch 1U chassis TFT screen produced by Shenzhen Hongjia Technology Co., Ltd. has an outer size of 34.76mm*47.86mm, which can be perfectly installed in a 1U chassis. It has a resolution of 240*320, 4 high-brightness lights, IPS full viewing angle, supports SPI and MCU interfaces, and can be displayed horizontally. Customers are welcome to email for consultation.

​Our company has successfully mass-produced 2.3-inch TFT horizontal screens with a resolution of 480*360 and IPS full viewing angles, filling the long-term vacancy in the 2.3-inch horizontal screen market with only low resolution and no full viewing angles.
