Description
SAEF TECHNOLOGY SF-TO350M-8840A-CT is a 3.5-inch liquid crystal
display unit that uses thin film transistors as active components
and includes pixels. This model consists of a single 3.5 (4:3) inch
transparent TN-LCD main panel. The resolution of this panel is 320
(RGB) x 240 pixels, and it can display up to 167M colors.
SF-TO350M-8840A-CT is equipped with a PCAP touch screen, which is a
G+G structure. SF-TO350M-8840A-CT supports RGB interface, and the
touch screen is IIC interface.
The SF-TO350M-8840A-CT TFT LCD module is widely used in handheld
devices such as black boxes, smart devices, mobile POS, cash
readers, GPS handheld phones, handheld ordering machines, signal
analyzers, desktop laboratory equipment, security systems, home
automation, mini audio players, and baby monitors.
