Description of lcd touch screen

Chenghao Optoelectronic CH400WV22A-CT is a 4.0-inch TFT LCD screen. The display module contains two main modules: a TFT LCD Panel and a Capacitive Touch Panel.
The TFT LCD Panel has a vertical display area with a diagonal length of 3.97 inches, which can display 480 x 800 pixel views. Thanks to the design of the IPS display mode, the TFT LCD Panel has an ultra-high contrast ratio (800:1) and supports free viewing angles (85/85/85/85).
The Capacitive Touch Panel contains a glass panel and a capacitive sensing module. The glass panel can be provided by the customer or designed by our company according to their requirements. The capacitive sensing module uses the I2C interface and supports multiple touch points, responsible for collecting touch signal from the screen, and is an important medium for achieving human-computer interaction.
To cope with the changing environmental temperature, CH400WV22A-CT uses a wide-temperature design. It performs well in environments ranging from -20°C to +70°C, and has a service life of over 30,000 hours.
It is worth mentioning that Chenghao Optoelectronic, as a long-time LCD manufacturer serving global customers, can provide various customized services such as FPC, TFT interface, and backlight luminance to customers. All of our LCD products can provide customers with FCC, RoHS, and CE certificates and a one-year quality guarantee.
