About this item Graphic FSTN COG LCD SFBM12864HX792
The graphic dot matrix FSTN COG LCD 128x64 dot VDD 3.3V monochrome
display module is a display solution designed specifically for
applications that require high clarity and reliability. The
following is a detailed introduction of the product:
- Resolution: 128x64 pixels, suitable for displaying text and basic
graphics.
- Display mode: FSTN (Film Super Twisted Nematic), providing high
contrast and wide viewing angle display effects.
- FSTN technology: Compared to traditional STN display technology,
FSTN improves display quality by adding compensation films,
providing clearer black and white display.
- COG (Chip On Glass) technology: The driver IC is directly bonded to
the glass, reducing the thickness and weight of the module while
improving reliability.
- Working voltage: 3.3V, suitable for battery powered portable
devices with low power consumption characteristics.
- Application scenarios:Suitable for devices such as instruments, medical equipment,
industrial control panels, household appliances, etc. that require
clear display of information.
Environmental adaptability:Working temperature range: usually between -20 ℃ and+70 ℃, able to
adapt to various environmental conditions.
Multiple interface options may be provided, such as SPI and MCU, to
facilitate connection with microcontrollers or other processors.
Backlight options:Backlight color: Provides multiple backlight color options such as
white, blue, yellow, and red to meet different design and usage
needs.
Customized services:According to customer needs, customized services may be provided,
including size, color, character shape, etc.
Environmental standards:Compliant with RoHS and REACH standards, ensuring the environmental
protection and safety of the product.
Multiple interface options may be provided, such as SPI and MCU, to
facilitate connection with microcontrollers or other processors.
This FSTN COG LCD display module is an ideal choice for various
application scenarios due to its high definition, low power
consumption, and high reliability.
