As a manufacturer specializing in capacitive touch solutions, we supply 4-inch 5-wire capacitive touch screens designed for stable performance in industrial and embedded environments. This model is frequently integrated into compact devices that require reliable user input, such as thermostats, handheld control panels, smart appliances, and medical terminals. Its G+G structure ensures durability under daily use, while the customizable interface options (I2C, USB, SPI, UART) allow easy adaptation to various host systems. We support low-volume prototyping and large-scale production, offering engineering support to match each customer's application scenario and electrical design.

By default, this 4-inch capacitive touch screen is RoHS-compliant, ensuring it meets the Restriction of Hazardous Substances Directive - a mandatory environmental standard within the EU that limits the use of substances like lead, mercury, and cadmium in electronic components. This is especially important for companies targeting international markets or adhering to global sustainability and safety standards.
For projects that require additional regulatory compliance - particularly in the medical, industrial, or automotive sectors - we can support CE (Conformité Européenne) and FCC (Federal Communications Commission) certification upon request. These certifications are typically needed if your final product will be marketed in Europe or North America, and require documented EMC (Electromagnetic Compatibility) and electrical safety compliance testing at the system level.
