This means that whether in the harsh outdoor conditions of northern winters or the high temperatures inside a car in summer, this 240×320 TFT LCD Display can operate stably, with strong anti-interference capabilities and an extremely low failure rate.

• Ready-to-Use Standard Interface and Driver Advantage: It uses a common 40PIN FPC interface and MCU parallel bus, with the core driver chip being ST7789.  Market resources are abundant, and sample code is readily available. Developers can quickly integrate it into projects such as Arduino or STM32, significantly shortening product development cycles.
• Compact Design and High-Definition Resolution Advantage: With a compact size of only 2.4 inches, it boasts a 240×320 QVGA resolution and high pixel density, making it particularly suitable for outdoor portable devices that need to display rich information (such as icons, Chinese characters, and data curves) on a small panel.

What does a 240×320 resolution mean? What kind of display effect does it produce when applied to a 2.4-inch display?

The 240×320 TFT LCD display achieves an impressive pixel density of approximately 166 PPI on its compact 2.4-inch screen. This means 76,800 individual pixels are finely arranged within the active display area (36.72mm x 49.26mm), with each pixel measuring a mere 0.153mm. Such a high-resolution layout in this small form factor results in exceptionally sharp and detailed visual output, effectively eliminating any grainy or pixelated appearance. The 240×320 resolution provides ample canvas space for clear text rendering—capable of displaying hundreds of characters—vibrant icons, and structured graphical user interfaces. This combination delivers a smooth and information-rich viewing experience, rivaling early smartphone displays, while maintaining an optimal balance between visual fidelity, power efficiency, and system performance. The 240×320 TFT LCD display thus transforms the 2.4-inch viewing area into a premium visual interface ideal for applications requiring both compact size and high-quality graphics.

Application areas of 240×320 TFT LCD displays

The 2.4-inch 240×320 TFT LCD display, due to its compact size, high definition, low power consumption, and excellent outdoor visibility, is primarily used in fields requiring miniaturized devices, information visualization, and strong environmental resistance.
