All productsWhat Is LTPS IPS?
LTPS IPS combines Low-Temperature Polysilicon (LTPS) backplane technology with In-Plane Switching (IPS) liquid crystal panels for high-performance displays. It delivers sharp resolution, fast response times, wide viewing angles, and low power consumption. LTPS IPS is ideal for smartphones, tablets, automotive dashboards, industrial monitors, and custom applications where compact, reliable, and bright displays are essential.
How Does LTPS Technology Work?
LTPS (Low-Temperature Polysilicon) converts amorphous silicon into polysilicon using laser annealing at approximately 600°C. This process increases electron mobility by over 100 times compared to a-Si, allowing integrated drivers directly on the glass and resolutions above 300 PPI. LTPS modules are thinner, more power-efficient, and suitable for system-on-panel designs.
Gesight leverages LTPS for custom TFT modules from BOE and AUO, achieving high-volume production with enhanced reliability and reduced component count.
| Feature Comparison | LTPS | a-Si |
|---|---|---|
| Electron Mobility | >100 cm²/Vs | <1 cm²/Vs |
| Resolution | 300+ PPI | <200 PPI |
| Power Consumption | Lower | Higher |
| Driver Integration | On-panel | External ICs |
| Response Time | ~12ms | Slower |
What Distinguishes IPS Panels?
IPS (In-Plane Switching) aligns liquid crystal molecules horizontally to provide 178° viewing angles without color shift. IPS panels offer accurate color reproduction, stable gamma, and faster pixel response compared with TN panels. Combined with LTPS, IPS achieves high pixel density and consistent brightness.
Gesight integrates IPS into high-brightness automotive and industrial displays up to 3000 nits, using LVDS or MIPI interfaces and rugged optical bonding.
How Does LTPS IPS Function?
LTPS IPS creates polysilicon TFTs on a glass substrate, followed by IPS electrode placement in-plane with liquid crystals. Laser annealing enables compact, high-speed transistors with embedded drivers. This structure ensures smooth refresh rates and uniform brightness. Peripheral circuits are integrated directly on the glass, minimizing bezel size.
What Are the Advantages of LTPS IPS?
LTPS IPS offers high pixel density, low power consumption, fast response, wide viewing angles, and integrated circuitry for slim, efficient designs. It reduces component counts, supports high-brightness operation, and enhances durability. LTPS optimizes electron mobility, ideal for mobile and industrial applications.
Gesight’s modules support multiple interfaces and touch options, serving medical, automotive, and industrial markets worldwide.
Which Applications Benefit from LTPS IPS?
LTPS IPS is used in smartphones, tablets, smartwatches, automotive HMIs, industrial monitors, AR/VR devices, and foldable displays. Its high resolution and efficiency improve gaming, video, and medical imaging.
Emerging applications leverage its flexibility and ruggedness, making it suitable for demanding environments.
Why Select LTPS IPS Over AMOLED?
LTPS IPS is cost-effective, durable, and free from burn-in while maintaining excellent color and viewing angles. AMOLED displays excel in contrast and black levels but can degrade faster outdoors. For high-bright environments, LTPS IPS offers stable performance and lower failure rates.
| Feature Comparison | LTPS IPS | AMOLED |
|---|---|---|
| Cost | Lower | Higher |
| Burn-in Risk | None | Possible |
| Brightness | Up to 3000 nits | High peak |
| Lifespan | Longer | Shorter outdoors |
| Viewing Angle | 178° | Excellent |
What Are the Limitations of LTPS IPS?
LTPS IPS costs more than standard a-Si IPS and requires precise laser processes. Its contrast ratio is lower than OLED (~500:1), and sunlight readability depends on high-bright variants. Solutions include rugged glass, optical bonding, and EMI-optimized firmware.
