All productsWhat Is a 5.5 Inch TFT LCD?
A 5.5 inch TFT LCD is a compact, high-performance thin-film transistor liquid crystal display with a 5.5-inch diagonal. It supports resolutions from 720×1280 to 4K UHD, IPS or TN panels, and interfaces like MIPI, LVDS, or HDMI. Ideal for industrial, automotive, and handheld applications, it delivers bright, vibrant visuals, optional touch, and reliable operation in varied environments.
What Are 5.5 Inch TFT LCD Specifications?
A 5.5 inch TFT LCD typically features resolutions from 720×1280 to 3840×2160, IPS or TN panels, and brightness levels of 400–1000 nits (up to 3000 nits in high-brightness models). Interfaces include MIPI, LVDS, HDMI, and Type-C. Dimensions range roughly 70–80 mm width and 120–140 mm height. Optional capacitive touch enhances interactivity. Operating temperatures span -20°C to 70°C, with rugged versions for industrial use.
| Specification | Typical Range | Notes |
|---|---|---|
| Resolution | 720×1280 to 3840×2160 | HD to 4K UHD |
| Brightness | 400–1000 nits | Up to 3000 nits for outdoor/industrial |
| Interface | MIPI, LVDS, HDMI, Type-C | Flexible connectivity |
| Panel Type | IPS, TN | IPS for wide viewing angles |
| Touch Option | Capacitive/Resistive | Optional based on project needs |

What Are Common Applications?
5.5 inch TFT LCDs are used in handheld devices, automotive dashboards, industrial controls, medical equipment, VR/AR systems, and embedded applications. Their compact size, wide viewing angles, and touch options make them ideal for portable media players, security monitoring, instrumentation, and outdoor signage.
High-brightness and ruggedized versions are suitable for outdoor displays or industrial machinery, while touch-enabled models enhance smart home interfaces and medical devices.
What Are the Advantages?
Advantages include vibrant 16.7M color depth, wide IPS viewing angles, low power relative to size, and seamless integration via standard interfaces. Compared to OLED, TFT LCDs offer longer lifespans (~50,000 hours) and better readability in direct sunlight. Ruggedization and touch integration make them suitable for industrial, automotive, and embedded solutions.
What Are the Disadvantages?
Disadvantages include higher power consumption than OLED and potential color shifts in TN panels. Non-IPS displays have narrower viewing angles. Limited flexibility restricts bending or folding without custom solutions. Mitigation includes choosing IPS panels, optical bonding, and selecting high-brightness versions for outdoor use.
How to Choose the Right One?
Select based on resolution, brightness, panel type, interface, touch requirements, and operating environment. Industrial or outdoor use demands high nits and ruggedization, while consumer devices prioritize cost-effectiveness. Verify supplier capability for custom interfaces like HDMI or Type-C and ensure environmental compliance for long-term reliability.
| Factor | Indoor Use | Outdoor/Industrial |
|---|---|---|
| Brightness | 400 nits | 1000–3000 nits |
| Panel Type | TN/IPS | IPS High-Bright |
| Touch | Optional | Rugged CTP |
| Temperature Range | -20°C–70°C | -30°C–80°C |
Gesight excels in customizing panels for automotive, medical, and embedded markets.
How to Integrate into Projects?
Integration involves connecting the LCD via MIPI or LVDS to microcontrollers like Raspberry Pi or Android boards. Controller boards enable HDMI/Type-C support. Testing for EMI/EMC and firmware compatibility is critical. Gesight provides full engineering support, including controller design, firmware customization, optical bonding, and environmental testing for seamless project integration.
What Innovations Exist?
Innovations include 4K resolutions, sunlight-readable displays up to 3000 nits, IGZO panels for low power consumption, and flexible OLED hybrids. Optical bonding reduces reflections, while high-PPI panels enhance VR and projector applications. Gesight offers advanced solutions with touch integration, high-brightness, and customized interface options, meeting industrial, automotive, and medical needs.
