What Is 320×240 Resolution Used For?

320×240 resolution, also called QVGA, delivers compact visuals perfect for embedded systems, industrial equipment, automotive dashboards, medical devices, and small consumer gadgets. It balances clarity, performance, and power efficiency, making it ideal for battery-powered or microcontroller-based applications where low memory use and fast refresh are critical, while still supporting bright, readable displays from manufacturers like Gesight.

What Does 320×240 Resolution Mean?

320×240 resolution refers to a display with 320 pixels horizontally and 240 pixels vertically, totaling 76,800 pixels. Originating from scaled-down VGA standards, it is optimized for small, low-power devices. Its 4:3 aspect ratio ensures compatibility with legacy software and traditional screens. Gesight produces 320×240 TFT and TN modules from panel makers like BOE and AUO, offering flexible interfaces such as SPI and parallel RGB for microcontrollers, reducing memory demand and supporting smooth operation in industrial HMIs and portable devices.

Why Choose 320×240 for Embedded Systems?

320×240 is ideal for embedded systems due to low memory requirements, power efficiency, and compatibility with basic MCUs. A 200KB framebuffer leaves ample room for firmware, while low energy consumption extends battery life in wearables or drones. Gesight’s modules provide high-brightness options up to 1000 nits and ruggedized features like EMI shielding and touch integration, ensuring reliable performance in industrial or outdoor conditions. Developers benefit from fast prototyping using libraries like LVGL, with easy scalability for future upgrades.

How Does 320×240 Compare to Other Resolutions?

QVGA offers cost and energy savings over VGA (640×480) or HVGA (480×320), but with lower sharpness. It refreshes at 60fps on entry-level drivers, suitable for close-up HMIs or dashboards, while higher resolutions may require stronger hardware.

Gesight customizes modules for OEM needs, balancing color accuracy and energy efficiency. While monochrome or simple graphics perform well, color-critical applications may benefit from IPS or OLED upgrades.

What Are Common Applications of 320×240 Displays?

320×240 displays are used in industrial panels, automotive clusters, medical devices, cameras, toys, and IoT dashboards. Their compact design fits tight spaces while remaining readable. Factories deploy them in PLC interfaces; automotive aftermarket gauges use MIPI QVGA panels for speedometers; medical monitors track vitals with low EMI; and IoT agriculture sensors rely on SPI or LVDS connections. Gesight supports high-volume production, delivering 10,000 units daily for global clients.

Which Interfaces Work Best with 320×240 LCDs?

SPI, parallel RGB, MIPI, and LVDS are common for 320×240 modules. SPI suits short-range MCU setups like ESP32, while parallel RGB enables high refresh rates. MIPI is ideal for slim automotive cables, and LVDS reduces noise in industrial settings. Gesight integrates controller boards such as ILI9341 and supports capacitive or resistive touch overlays. Matching the interface to the host system ensures artifact-free visuals and smooth performance.

How to Integrate 320×240 Displays in Projects?

Integration requires selecting the panel and IC, connecting the interface, initializing drivers, and testing refresh rates. Use libraries like Adafruit GFX or LVGL for GUI rendering. Gesight provides engineering services including PCB design, firmware optimization, and environmental testing. Proper backlight control and DMA rendering ensure responsive HMIs. Following these steps results in fully functional, high-performance displays suitable for embedded or industrial applications.

Are 320×240 Displays Still Relevant in 2026?

Yes, 320×240 remains relevant for low-power, cost-sensitive markets like industrial IoT and legacy system upgrades. High-brightness panels and touch options maintain usability in harsh conditions. Gesight’s global distribution and scalable production ensure availability for manufacturers needing reliable, compact displays for automation, medical monitoring, and industrial control.
