RGB 9 Inch TFT with RTP Product Introduction
SFTO900SH-7170A4T is an 800 × 4800 high brightness TN TFT LCD
display. The module size is 211.1(W)×126.5(H)×7.3(D) mm, with an
effective area of 201.8 × 114.5 mm and a diagonal dimension of 9
inches. This TFT module adopts TN technology, with a typical aspect
ratio of 4:3 and a wide viewing angle (70/70/50/70 degrees), which
has a good cost advantage and enhances customers' visual experience
of its products.
In addition, SFTO900SH-7170A4T offers three product features: high
brightness (1000 cd/m2), high contrast (800:1), and anti glare.
These features improve image display in complex lighting
environments, enhancing the visual experience of customer products
under various conditions.
The TFT module adopts 24 bit RGB interface (connector Hirose
FT12A-50S-0.5H). The 9 inch series is an optional configuration for
LVDS, MIPI, and RGB interfaces, depending on the requirements of
the customer's MCU.
