2.8-inch round screen is widely used in smart home, home appliances, industrial instruments and equipment, beauty instruments and other products, true round screen display, upscale design, welcome customers to email consultation, we provide technical support, also support customized services.

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.

TN LCD screen glass has high transmittance. Under the same backlight conditions, TN will have higher brightness. TN glass cost is relatively cheap, which is more cost-effective for customers with price requirements; IPS is better than TN in terms of viewing angle, display effect and other parameters, but the unit price is relatively higher. Customers need to choose according to the positioning of their products. Shenzhen Hongjia Technology specializes in the production of 1.14-inch to 10.1-inch LCD screens and matching touch screens. Both TN and IPS are available, with complete sizes and multiple interfaces. Customers are welcome to email for consultation.

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).

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.

Shenzhen Hongjia Technology focuses on 1.14-inch to 10.1-inch displays and matching touch screens. The company has many experienced TFT engineers who can provide customers with solutions to problems, including one-stop technical support before, during and after sales, and assist customers in the smooth mass production of projects.
