Display Drivers

Display driver power management integrated circuits are the core control units of the display system, responsible for precisely driving pixels and optimizing power distribution.

 

1. What are the Mainstream Types of Display Driver PMIC? 

1) LCD Driver Chip

TFT-LCD Driver Chip: Designed for thin-film transistor displays, it supports high resolution and fast response times, and is widely used in TVs, monitors, and mid-to-high-end mobile phones.

STN-LCD Driver Chip: Suitable for low-resolution devices such as early electronic watches and basic displays.

 

2) OLED Driver Chip

PMOLED Driver Chip: Utilizes a passive matrix drive system and is commonly found in small-screen devices such as smart bracelets.

AMOLED Driver Chip: Based on active matrix technology, it supports high refresh rates and high contrast, dominating the flagship mobile phone and high-end TV markets. Its core technology integrates a power management unit (PMIC), significantly reducing power consumption and improving battery life.

 

3) Micro-LED Driver Chip

Supports independent driving of ultra-large pixels, meeting the stringent requirements of AR/VR devices for ultra-high brightness and low power consumption.

 

4) Touch Display Integrated Circuit (TDDI)

Integrates touch and display functions into a single chip, reducing device space and optimizing response speed (latency <15ms). Widely used in mobile phones and tablets.

 

2. Core Technology Innovation of Display Driver PMIC

AMOLED-PMIC Integrated Design: Embedding the power management IC into the display driver chip reduces power consumption by 30% and lowers costs, providing long-lasting battery life for wearable devices.

Dynamic Frame Rate Adjustment: Supports a 165Hz high refresh rate and adaptive frame rate technology, eliminating screen tearing and reducing rendering processing requirements.

Anti-interference Optimization: The next-generation AFE architecture improves touch signal-to-noise ratio, resolving noise-induced touch failure issues.

 

3. Expanding Application Areas of Display Driver PMIC

This chip covers smartphones, tablets, smart wearables (such as the Xiaomi Mi Band and Xiaotiancai Watch), automotive displays, and AR/VR devices, and is compatible with various panel technologies, including a-Si, LTPS, and IGZO.

 

Future development trends will focus on higher integration, lower power consumption, and multi-technology integration (such as the combination of Micro-LED and TDDI) to meet the needs of ultra-thin flexible displays.
