Low Cost 2.4 inch QVGA TFT LCD Product Introduction
2.4-inch 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 (262K color). This model
SFTO240JY-7182AN has an SPI interface and can achieve a brightness
of 400cd/m ², adapting to different lighting conditions. 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.
This 2.4-inch QVGA TFT display is widely used in various fields
such as medical equipment, industrial control, smart homes, and car
navigation. Their high brightness (up to 1000 nits) and contrast
make them still clearly visible outdoors or in direct sunlight. Low
cost is a major advantage of the 2.4-inch TFT 240 * 320 dot matrix
product SFTO240JY-7182AN, making it an ideal choice for projects
with limited budgets but requiring good display performance.
For developers, driver support for display screens and development
libraries are equally important. SFTM240JY-7182AN (with PCB)
support development libraries such as GFX Library for Arduino,
providing efficient display performance and simplified development
processes.
