QWhat is the driver IC and interface mode of the H024HQ40E2543 LCD module?
The module utilizes the ST7789V controller IC and supports an 8-bit/16-bit 40-pin MCU parallel interface as well as serial SPI control modes for high-speed graphics transmission.
QCan this 2.4-inch display be customized with a touch panel?
Yes. Although the standard model comes without a touch screen, capacitive touch screen (CTP) and resistive touch screen (RTP) solutions can be custom integrated upon request.
QWhat are the supported operating and storage temperatures?
The operating temperature range is -20°C to +70°C, and the storage temperature range is -30°C to +80°C, allowing dependable performance in industrial and commercial environments.
QWhat is the optimal viewing direction for this TN TFT LCD?
The display is designed with a 12 o’clock viewing angle, making it ideal for handheld devices, portable testing terminals, and upright equipment panels.
QWhat are the typical operating voltages for logic and backlighting?
The logic power supply (IOVCC/VCI) operates between 2.8V and 3.3V (typically 3.2V), while the LED backlight operates between 3.0V and 3.4V (typical 3.2V).
QIn which applications is this 2.4-inch module commonly utilized?
Common applications include industrial portable detectors, data acquisition terminals, medical instruments (such as blood glucose monitors), and smart home devices like digital thermostats and smart locks.
