What happened to transflective displays?

In recent years, transflective displays have undergone significant evolution across four key dimensions: materials, structure, driving mechanisms, and application scenarios. They have evolved from early, simple solutions—designed merely to "balance outdoor visibility with low power consumption"—into a new generation of display technology characterized by full-scenario adaptability, high image quality, low power consumption, and flexibility.

1. Core Technology Advancements

Optical Materials and Structures

It uses special tiny particles and special reflective layers to make the light reflect back up to 30% more, while still letting 50% of the light through.

Polarisers with a high transmission and low haze rating can achieve an outdoor contrast ratio of over 1000:1.

Using a combination of special films and tiny lenses helps to fix problems with colour shift and uneven grey tones.

Drive and Control Systems

MIP Pixel Memory: It uses very little energy when it is not being used, which means that in total it can save 70% to 90% of energy.

Light-sensing technology lets you switch between reflective and transmissive modes in under 100 milliseconds, and the brightness levels range from 50 to 1500 cd/m².

Low-power ICs support ultra-low refresh rates (less than 1 Hz) and updates to just a part of the screen.

Image Quality and Form Factor

Full-color capability (NTSC 85%+) with a maximum refresh rate of 60Hz.

Ultra-thin profile (<0.3mm) with flexible, bendable properties.

Outdoor brightness of 1500 cd/m², offering high resistance to strong ambient light (up to 100,000 lux).

1. Application Expansion

Wearables: Smartwatches and fitness bands (featuring high visibility and extended battery life).

Industrial/Medical/Military: Applications requiring performance in strong lighting conditions and harsh environments.

Retail/IoT: Electronic shelf labels (they last 3–5 years).

Automotive/Transportation: HUDs (Head-Up Displays), central control panels, and outdoor display screens.

E-Paper Integration: It supports a full colour display and dynamic content refreshing.

1. Market Positioning

This is a change from a small, less important technology to a key solution for outdoor and low-power display applications.

The cost has been reduced by more than 50%, which is making it more popular.

1. Future Trends

Micro LED Integration: Combining high brightness with low power consumption.

AR/VR Pancake Optics: Enabling thinner and lighter form factors.

Transparent Displays: Realizing "suspended imaging" effects.

Summary: This display technology started out as a compromise, but has now become popular. It is bright, uses low power and can be used in many different ways.
