Product Description

The CH240QV64A is a 2.4-inch IPS TFT LCD module with 240x320 resolution, 4-Line SPI interface, and 300cd/m2 brightness, designed for compact embedded systems. Featuring full 80/80/80/80 viewing angles and a transmissive normally-black display mode, it delivers sharp contrast and consistent color from any direction. The module supports a wide operating temperature range of -20°C to +70°C, making it suitable for industrial control panels, portable instruments, and outdoor handheld devices. With a compact 10-pin SPI connection, this display enables straightforward integration with low-pin-count MCUs while maintaining crisp 240x320 pixel rendering. The IPS panel ensures sunlight readability when paired with proper enclosure design, while the normally-black mode delivers deep blacks and excellent contrast ratio for applications demanding clear data visualization in varying ambient light conditions.

Product Features

1. Compact 2.4-Inch IPS Display for Space-Constrained Embedded Systems

The small 2.4-inch form factor fits into handheld meters, portable diagnostic tools, and compact IoT control panels where every millimeter of enclosure space matters.

2. Full 80/80/80/80 Viewing Angles for Multi-Position Readability

IPS panel technology ensures consistent color and contrast from any viewing direction, enabling operators to read data clearly from off-axis positions in industrial equipment panels and monitoring stations.

3. Wide Operating Temperature Range (-20°C to +70°C)

Reliable performance across extreme environments makes this module suitable for outdoor instrumentation, cold-chain logistics trackers, and factory-floor control interfaces exposed to temperature swings.

4. Simple 4-Line SPI Interface for Low-Pin-Count MCU Integration

With just 10 pins and a straightforward SPI protocol, this display connects easily to resource-constrained microcontrollers, reducing PCB complexity and accelerating prototype development.

5. Transmissive Normally-Black Mode with 300cd/m² Brightness

The normally-black display mode delivers deep blacks and high contrast for crisp data visualization, while 300cd/m² brightness ensures legibility in indoor and shaded outdoor environments.
