240×320 TFT LCD modules deliver sharp QVGA resolution (240×320 pixels) with vivid color reproduction and wide viewing angles, ideal for embedded systems, industrial HMI, medical devices, and consumer electronics. Their 3.5” to 4” sizes, 16-bit RGB interface, and 300-500 cd/m² brightness ensure readability under sunlight. Panox Display’s modules integrate IPS technology for 170°+ viewing angles and support SPI/MCU interfaces, enabling seamless compatibility with Raspberry Pi and Arduino.
How Does Flexible Display Technology Transform Modern Electronics?
Why is 240×320 resolution optimal for embedded systems?
The 240×320 (QVGA) resolution balances clarity and processing efficiency, offering 76,800 pixels—enough for detailed icons/text without overloading microcontrollers. Compatible with 16-bit color depth (65K colors), it maintains smooth GUI rendering even on entry-level SoCs like STM32F4.
Unlike higher resolutions (e.g., 480×800), QVGA requires less RAM (150KB vs. 750KB for framebuffer) and lower clock speeds, reducing power consumption. For example, Panox Display’s 3.5” 240×320 TFT draws 120mA at 3.3V, ideal for battery-powered IoT devices. Pro Tip: Pair SPI-based modules with DMA controllers to offload CPU usage. Think of it as a smartphone screen shrunk for embedded use—sharp enough for graphs but frugal on resources.
| Resolution | RAM Usage | Typical Applications |
|---|---|---|
| 240×320 | 150KB | Industrial HMIs, Wearables |
| 480×272 | 255KB | Car Dashboards |
| 800×480 | 750KB | Advanced Medical Devices |
How do these modules enhance industrial HMI displays?
Industrial HMIs demand sunlight-readable screens with wide temperature ranges (-30°C to 80°C). Panox Display’s 240×320 TFTs use LED backlighting with 500 cd/m² brightness and resistive/capacitive touch options, enduring factory vibrations and moisture.
Their 4-wire resistive touchscreens support gloved inputs—critical for manufacturing lines. With a 16ms response time, they prevent lag during rapid parameter adjustments. Pro Tip: Opt for optical bonding to eliminate air gaps, reducing glare by 60%. Imagine an automotive dashboard: readable in direct sunlight, responsive to touch, and immune to temperature swings.
What makes 240×320 TFTs suitable for medical devices?
Medical gear requires EMI-resistant displays with precise color accuracy. Panox Display’s modules feature shielded LVDS interfaces and 72% NTSC color gamut, critical for ultrasound imaging and vital sign monitors.
They’re compliant with ISO 13485 standards, ensuring reliability in sterilization cycles. A 3.5” 240×320 TFT in a portable ECG monitor provides clear waveform visuals while drawing under 0.5W. Practically speaking, these modules are the unsung heroes in operating rooms, delivering life-critical data without flicker or lag. But what if a surgeon needs to view the screen from an angle? IPS panels maintain color consistency even at 178°.
| Feature | Medical Grade | Consumer Grade |
|---|---|---|
| Temperature Range | -30°C to 85°C | 0°C to 50°C |
| EMI Shielding | Yes | No |
| MTBF | 50,000 hrs | 20,000 hrs |
How does power efficiency benefit portable devices?
At 3.3V operation and dynamic backlight control, 240×320 TFTs extend battery life in handheld scanners or drones. Panox Display’s modules with PMOLED backlight drivers cut power by 30% via dimming idle zones.
A drone telemetry screen using this tech can last 8+ hours on a 2000mAh battery. Pro Tip: Enable sleep modes during inactivity—drops consumption to 5mA. Think of it like a hybrid car’s engine: ramping down when full brightness isn’t needed.

Can these displays handle custom interfaces?
Yes, Panox Display offers custom FPC connectors and pinouts, adapting 240×320 TFTs for legacy industrial PCs or proprietary ARM boards. Their modules support MIPI DSI, SPI, and RGB interfaces—no need for costly signal converters.
For instance, a client’s CNC machine required a 40-pin FPC with reversed scan direction; Panox delivered a drop-in solution in 3 weeks. Remember, while customization adds lead time, it eliminates external adapters, saving space and cost. Why force a square peg into a round hole when you can reshape the peg?

FAQs
Only if your MCU has enough RAM and GPIOs. Upgrading from 20KB to 150KB framebuffer often requires a processor upgrade—consult Panox Display’s compatibility matrix first.
Do 240×320 TFTs support multi-touch?
Capacitive versions support 2-point touch, but resistive types are single-touch. For industrial use, resistive is preferred for glove compatibility.
