In the digital era, screens have become essential media for work, study, and entertainment. As screen time continues to increase, “eye protection” has gradually become a core consideration for consumers when purchasing electronic devices.
So, how does TFT screen perform? Compared to OLED, which display technology is more beneficial for eye health? Let’s take an in-depth look at the characteristics of these two types of displays.
1. Key Features of TFT Screens
As a mature LCD display technology, TFT screens maintain an important position in the market due to the following advantages:
True Color Reproduction: Natural and accurate color representation, especially suitable for text reading and office scenarios.
High Cost Performance: Production costs are significantly lower than OLED, making it an ideal choice for budget-conscious users.
Long Lifespan: The non-self-emissive property effectively avoids burn-in issues, ensuring better device durability.
However, TFT screens have certain limitations in contrast performance, black level purity, and viewing angles.
2. Breakthrough Advantages of OLED Screens
In recent years, OLED technology has rapidly gained popularity in high-end display fields, with standout advantages including:
Infinite Contrast: Pixel-level light control achieves true black display.
Ultra-Fast Response: Nearly zero-latency refresh rates, perfect for high-speed dynamic visuals.
Innovative Form Factor: Ultra-thin and bendable properties have ushered in a new era of foldable devices.
Note: OLED may have higher blue light intensity and potential image retention issues with long-term static display.
3. In-Depth Comparison of Eye Protection Performance
Blue Light Emission
OLED: Uses blue LED light sources with a higher proportion of blue light in the spectrum.
TFT: Backlight systems can more easily integrate blue light filtering technology to reduce harmful blue light exposure.
Screen Dimming
OLED: Often uses PWM dimming at low brightness, which may cause eye strain.
TFT: Typically employs DC dimming for more stable light output.
Environmental Adaptability
OLED: Excellent in low-light environments but limited brightness improvement in strong light.
TFT: High brightness ensures clear visibility outdoors.
Usage Recommendations
Long work/reading sessions: Devices with TFT screens are recommended.
Multimedia entertainment: OLED screens deliver a more immersive visual experience.
4. Purchasing Guide
Eye Health First: Choose TFT screen products with low blue light certification.
Premium Visuals: OLED screens offer top-tier visual enjoyment.
Budget Considerations: TFT screens provide the best cost-performance solution.
Future Trends: OLED is gradually addressing eye protection concerns as technology advances.
