Low Cost 2.4 inch QVGA TFT LCD Product Introduction
Saef Technology specializes in producing TFT display screens and
touch screens. We can also provide customized services according to
customer requirements. Due to the large-scale production of 2.4
"TFT LCDs, our company has achieved good control and optimization
of product costs, resulting in extremely high cost-effectiveness.
Therefore, more users will choose SAEF as their long-term partner.
2.4-inch TFT display SFTO240JY-7182AN 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 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.
