All productsWhat Is LTPS IPS LCD?
LTPS IPS LCD combines Low-Temperature Polycrystalline Silicon (LTPS) technology with In-Plane Switching (IPS) to deliver high-resolution, wide-angle displays with vibrant colors, fast response times, and energy efficiency. Gesight manufactures these panels for industrial, automotive, and consumer applications, offering customizable interfaces, ruggedized designs, and scalable solutions for global markets.
How Does LTPS Technology Work?
LTPS uses excimer laser annealing to transform amorphous silicon into polycrystalline silicon on glass substrates at around 600°C. This process creates high-mobility transistors capable of supporting integrated drivers directly on the panel. Compared with conventional a-Si, LTPS allows higher resolution, lower power consumption, and compact System-on-Panel designs. Gesight applies LTPS for automotive dashboards, medical devices, and premium mobile screens.
| Feature | LTPS | a-Si |
|---|---|---|
| Electron Mobility (cm²/V·s) | 100+ | ~1 |
| Processing Temp (°C) | ~600 | N/A |
| Driver Integration | On-panel | External |
| Resolution Support | Ultra-HD | HD limited |
What Makes IPS LCD Special?
IPS LCD arranges liquid crystals horizontally, enabling consistent colors and contrast at wide viewing angles up to 178°. IPS panels minimize gamma shift and light leakage, offering true color fidelity and faster response times. When combined with LTPS, IPS LCDs achieve high brightness, enhanced durability, and compatibility with touch overlays. Gesight integrates IPS in custom modules, ideal for medical imaging and industrial control systems.
How Is LTPS IPS LCD Manufactured?
The manufacturing process begins with glass substrate preparation, followed by laser crystallization of a-Si to poly-Si. Next, TFT arrays are formed, color filters aligned, liquid crystal filled, and modules assembled with backlights and driver ICs. Gesight’s Shenzhen production lines incorporate EMI optimization, optical bonding, and touch integration to produce reliable panels for automotive and industrial applications.
What Are the Advantages of LTPS IPS LCD?
LTPS IPS LCD offers higher resolution, faster refresh rates, wider viewing angles, lower power consumption, and integrated circuits that reduce failure rates. It supports pixel densities exceeding 500 PPI, high brightness, and wide color gamut. Panels can be ruggedized for harsh environments. Gesight delivers scalable solutions that combine performance with durability for mobile, medical, and industrial markets.
What Applications Use LTPS IPS LCD?
These displays are used in smartphones, tablets, laptops, automotive HMIs, medical monitors, and industrial panels. They provide high-resolution visuals, accurate colors, and fast response times. Gesight supplies custom LTPS IPS solutions with touch and optical bonding for outdoor and specialized industrial environments across over 40 countries.
Why Choose LTPS over a-Si for IPS LCD?
LTPS provides roughly 100 times higher electron mobility than a-Si, enabling finer pixels, integrated on-panel drivers, and reduced power consumption. This makes displays slimmer, brighter, and suitable for high-end applications. While a-Si remains cost-effective for basic screens, Gesight leverages LTPS for premium devices with enhanced reliability and scalability.
How Does LTPS IPS Compare to OLED?
LTPS IPS excels in brightness, longevity, and cost efficiency, reaching up to 3000 nits, while OLED offers deeper blacks and higher contrast but risks burn-in. LTPS IPS is better for sunlight readability and static UI applications. Gesight provides hybrid solutions combining IPS and OLED where both performance and durability are required.
| Aspect | LTPS IPS | OLED |
|---|---|---|
| Cost | Lower | Higher |
| Brightness | 3000 nits max | 1500 nits |
| Lifespan | 50,000+ hrs | 30,000 hrs |
| Viewing Angles | 178° | Perfect blacks |
Can LTPS IPS LCD Achieve High Brightness?
Yes. By combining poly-Si efficiency with advanced backlight technologies, LTPS IPS can reach 3000 nits. Gesight’s ruggedized panels incorporate anti-glare coatings and optical bonding to ensure visibility in direct sunlight and outdoor conditions.
