About this item: Lowest price guarantee 1.77 inch TFT LCD
The 1.77-inch TFT LCD meets the market's demand for
miniaturization, low power consumption, and high-definition
displays with its moderate size and high performance. It has
obvious market advantages in portable electronic devices and other
fields, while also demonstrating its unique value in professional
fields such as industry and healthcare. In the industrial field,
1.77-inch TFT LCD is commonly used to display the operating status
and parameters of instruments, such as temperature and humidity
meters, pressure gauges, etc. This display screen can also be used
as an interface for automation control systems, providing real-time
data monitoring and operational feedback.
The commonly used driver chip is ST7735S, which supports SPI
interface and is easy to integrate into various systems. The
product brightness can reach 300cd/m ², suitable for different
indoor and outdoor lighting conditions. Usually equipped with 2 LED
lights to provide uniform backlight effect.
Our company has an absolute cost advantage in this type of product and guarantees to provide customers with high-quality products at the lowest prices in the industry.
