What Is LTPS Display?

LTPS (Low-Temperature Polycrystalline Silicon) display technology transforms traditional LCDs with faster electron mobility, enabling higher resolution, quicker response times, and improved energy efficiency. Its compact transistor structure supports pixel densities over 200 dpi and on-glass driver integration, making it ideal for smartphones, tablets, automotive dashboards, and industrial panels, where clarity, speed, and durability are crucial.

What Is LTPS Technology?

LTPS, or Low-Temperature Polycrystalline Silicon, is a TFT backplane technique that converts amorphous silicon into polycrystalline grains via laser annealing at 300–650°C. This significantly increases electron mobility, allowing smaller transistors, higher resolutions, and integrated circuits directly on the glass substrate.

By reducing component count and improving speed, LTPS enables compact, high-performance panels. Gesight integrates LTPS in custom LCD modules for automotive and industrial use, pairing panels from BOE, AUO, or LG with high-brightness, ruggedized designs up to 3000 nits. Key advantages include:

  • Higher Resolution: Smaller transistors allow denser pixels.

  • Faster Response: 12ms switching reduces motion blur.

  • Energy Efficiency: Lower power consumption prolongs battery life.

Gesight’s LTPS displays support versatile interfaces such as MIPI, LVDS, and Type-C, tailored for embedded and medical systems.

How Does LTPS Improve Display Performance?

LTPS achieves superior performance through its ordered polycrystalline silicon structure, allowing electrons to move roughly 100 times faster than in amorphous silicon. This enables precise pixel control, supporting 4K resolutions, 500 nits brightness, and high contrast ratios.

Fewer components and connections reduce failure risks while enabling system-on-glass integration. Response times reach 12ms, viewing angles expand to 170°, and power efficiency improves. Gesight applies LTPS in OEM/ODM IPS and TN panels with optical bonding and capacitive/resistive touch, suitable for industrial and consumer devices.

This comparison highlights why LTPS underpins high-end displays.

What Are LTPS Display Advantages?

LTPS displays deliver high resolution, fast response, energy efficiency, and brightness. Their thin design reduces IC count, enhancing reliability and heat management. Gesight customizes LTPS modules with optical bonding, rugged cover glass, and EMI/EMC optimization for automotive, industrial, and medical applications.

Core advantages:

  • Dynamic colors and clarity

  • Lower production temperatures

  • Enhanced brightness and viewing angles

  • Scalability for various panel sizes

These traits make LTPS an optimal choice for demanding environments.

What Are LTPS Display Disadvantages?

LTPS production involves complex laser processes, increasing costs compared to a-Si. High currents can affect lifespan, and uniformity may vary on larger substrates.

Gesight mitigates these issues with automated production lines capable of 10,000 units per day and rigorous testing to ensure durability, especially in industrial and automotive sectors. For high-performance applications, LTPS advantages outweigh potential drawbacks.

Why Choose LTPS for High-Resolution Devices?

LTPS supports dense pixels and low power consumption, making it ideal for smartphones, tablets, and laptops needing high-resolution displays and smooth motion.

4K devices benefit from LTPS’s fast electron mobility, low leakage, and system-on-glass integration. Gesight leverages Sharp and JDI modules for industrial HMI, optimizing rugged glass, firmware, and high-brightness options for real-world conditions.

How Is LTPS Manufactured?

LTPS panels begin with amorphous silicon deposition on glass, followed by laser annealing at low temperatures to form polycrystalline grains. TFT arrays are then patterned, and LCD layers are added.
