Victronix Tecesntar’s latest TRANSFLECTIVE TFT Displays specifically target demanding outdoor applications. This kind of LCDs can be readable in direct sunlight conditions, providing users with a clear image, because they’re designed with an internal transreflector.

The custom and standard TFT modules come in 320*240 (QVGA) resolution in 1.74 inch, 2.4 inch, 3.5 inch in sizes, and 800*480 (WVGA) in 5.0 inch in size. Standard brightness ranges from 80 to 160 nits, depending on the size. Additional options (e.g., resistive and projected capacitive touch panels, light guide features, and flex modifications) also can be incorporated.

Today, let’s talk about how the transflective LCDS works? And what advantages and disadvantages compared to transmissive LCDS and reflective LCDS.

Based on their light modulation methods, LCDs can be categorized into three main types: transmissive LCDs, reflective LCDs, and transflective LCDs. Each type has distinct working principles, advantages, and limitations. Below, we provide a detailed comparison to help customers select the most suitable solution for their needs.

1. Transmissive LCD

Working Principle:

Transmissive LCDs rely on a backlight unit (BLU) as their primary light source. The liquid crystal layer modulates the light from the backlight, allowing or blocking its passage through polarizers to create images.

Advantages:

High brightness and vivid colors, ideal for indoor use.

Excellent contrast and wide viewing angles.

Suitable for applications requiring rich graphical content (e.g., smartphones, monitors, TV, digital cameras, automotive displays, navigation systems, medical equipment, kiosks, and point-of-sale (POS) terminals).

Disadvantages:

Poor visibility in direct sunlight due to reliance on backlight.

Higher power consumption due to constant backlight usage.

Limited outdoor usability.

2. Reflective LCD

Working Principle:

Reflective LCDs utilize ambient light instead of a backlight. A reflective layer (usually behind the LC layer) bounces external light back through the display, making it visible.

Advantages:

Ultra-low power consumption (no backlight needed).

Excellent sunlight readability.

Lightweight and thin design, making them well-suited for portable devices.

Disadvantages:

Poor performance in low-light conditions (requires external lighting).

Lower contrast and color vibrancy compared to transmissive LCDs.

Limited use in dark environments.

3. Transflective LCD (Combined Solution)

Working Principle:

Transflective LCDs combine transmissive and reflective technologies. They feature a partially reflective layer that allows the display to use both backlight and ambient light. In bright conditions, it acts like a reflective LCD, while in darkness, the backlight supplements visibility.

Advantages:

Balanced performance in both indoor and outdoor environments.

Energy-efficient (reduces backlight dependency under sunlight).

Good sunlight readability while maintaining decent color quality.

Disadvantages:

Slightly higher cost due to hybrid design.

May not match transmissive LCDs in pure color richness or reflective LCDs in power savings.

Why Choose Transflective LCDs?

For customers needing a universal display that performs well in both sunlight and low-light conditions (e.g., marine equipment, outdoor handheld devices, automotive dashboards), our transflective LCDs offer the best compromise between visibility and power efficiency.
