China 3.17 inch touch screen 320*480 mcu Manufacturers, Suppliers, Factory

​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.

How to choose between amorphous silicon (a-Si) and low temperature polysilicon (LTPS) for project development with display

At present, the touch technologies applied to products mainly include infrared, resistive, capacitive, surface acoustic wave, optical image, image recognition, panel induction, electromagnetic, light spot, and ultrasonic. The following is an analysis of the advantages and disadvantages of various touch technologies.

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.

In addition, when designing the touch screen circuit principle, the grounding of the FPC cable can be increased, or the touch screen cable can be covered with double-sided black electromagnetic film, which can also reduce the electromagnetic interference problem of the touch screen in practical applications. Shenzhen Hongjia Technology has been professionally developing and producing 1.14-inch to 10.1-inch displays and supporting touch screens for 12 years. It has a R&D team of more than 20 people who are familiar with solving common problems in the industry and can reduce troubles for customers.
