What is the operating voltage and backlight for this screen?
A:
The specific operating voltage and backlight details must be confirmed in the official datasheet. Typically, the core logic voltage for such monochrome FSTN-LCD modules can be 3.3V or 5V. Regarding the backlight, it might come without one, or have an optional LED side-light (often yellow or white). If a backlight is included, its driving voltage and current will be specified separately.
Q:
What products or devices is this display commonly used in?
A:
Due to its low power consumption, high reliability, and cost-effectiveness, it is well-suited for various industrial control and consumer electronics fields. Examples include portable instrumentation, handheld devices, HMI for industrial controllers, display panels for home appliances, auxiliary screens for medical devices, and older pagers or walkie-talkies.
Q:
What is the interface of this LCM module and is it easy to integrate into my project?
A:
The "LCM" in the product name indicates it's a Liquid Crystal Module, which typically includes the driver circuitry. For such standard industrial modules, the common interface is a parallel MCU interface (like 8080 or 6800 series). The exact interface type should be confirmed in the G321EV5R00X datasheet. Integration is of moderate difficulty; you will need an MCU with sufficient GPIO pins or a dedicated LCD controller to drive it, along with writing corresponding initialization and display driver code.
Q:
What type of LCD technology does it use and what are its characteristics?
A:
It uses FSTN-LCD (Film Compensated Super Twisted Nematic) technology. FSTN is an improved version of STN, offering higher contrast and wider viewing angles, resulting in a clearer monochrome image (typically blue on white or black on white) compared to standard STN. It is a passive-matrix display and can be very power-efficient, especially when readable under ambient light without a backlight.
Q:
What is the resolution of this 4.7-inch screen and how is the clarity?
A:
This display has a QVGA resolution (320 x 240 pixels). Its pixel density is approximately 84 PPI. For a 4.7-inch screen, this PPI is relatively low, so the display may not be very sharp. However, it is well-suited for industrial or basic HMI applications that prioritize low power consumption and cost over displaying complex, high-definition graphics.
