SPI interface 2.4 inch TFT LCD Product Introduction
The 2.4-inch TFT LCD screen is a common active matrix LCD display
device with high resolution, vivid colors, and fast response speed.
It is widely used in embedded systems, consumer electronics,
industrial control fields, and more. In the field of consumer
electronics, 2.4-inch TFT LCD screens are widely used in smart
wearable devices, portable game consoles, smart home control
panels, and other products. Its full color and wide viewing angle
meet consumers' requirements for display effects.
2.4-inch IPS TFT display with a resolution of 240 × 320 pixels
provides clear image display. Its driver IC is ST7789V and supports
multiple interfaces and high color depth. This model
SFTO240JY-7179AN has an SPI interface and can achieve a brightness
of 400cd/m ², adapting to different lighting conditions. It adopts
IPS technology, providing a nearly 180 ° full field of view,
ensuring a good visual experience from all angles. The product can
operate between -20 ℃ and 70 ℃ and adapt to various environmental
conditions. It can be stored between -30 ℃ and 80 ℃, ensuring that
long-term storage will not affect its performance.
