Applications of TFT and AMOLED in industrial design: What are the differences between them?

In the field of industrial design, the choice of display technology is crucial to product performance and user experience. TFT (Thin Film Transistor) and AMOLED (Active Matrix Organic Light Emitting Diode) are two mainstream display technologies, each with unique advantages and disadvantages, suitable for different application scenarios. LEEHON Technology, as a professional display technology provider, is committed to providing customized display solutions for industrial clients.

I. Performance Comparison of TFT and AMOLED

(I) Contrast Ratio

TFT: Relies on backlighting, blacks are relatively gray, contrast ratio is typically around 1000:1.

AMOLED: Pixels can be completely turned off, achieving pure black, contrast ratio is close to infinite.

(II) Color Performance

TFT: Narrow color gamut, high-end IPS screens have better color accuracy.

AMOLED: Vivid colors, wide color gamut, but may be oversaturated.

(III) Response Time

TFT: Slow response time, prone to ghosting, especially in low-end TN/VA panels.

AMOLED: Extremely fast response time (microsecond level), suitable for high-speed dynamic images.

(IV) Viewing Angle

TFT: IPS screens have a wider viewing angle, but brightness still decreases.

AMOLED: Almost no viewing angle limitation, high color consistency.

(V) Power Consumption

TFT: Power consumption is fixed when backlight is on.

AMOLED: More energy-efficient for displaying dark colors, but consumes more power for full white images.

(VI) Thickness and Flexibility

TFT: Relatively thick, cannot be bent.

AMOLED: Ultra-thin, can be used for flexible/foldable screens.

(VII) Lifespan

TFT: Long backlight lifespan, suitable for displaying static content for extended periods.

AMOLED: Organic materials are prone to degradation, and prolonged high brightness can cause screen burn-in.

II. Application Scenarios Comparison

(I) TFT Application Scenarios

Industrial Equipment: The durability and stability of TFT make it an ideal choice for industrial control panels and monitoring equipment.

Automotive Screens: The reliability and long lifespan of TFT make it widely used in automotive dashboards and central control screens.

Large-Size Displays: In the television and monitor field, TFT dominates due to its cost advantage. (II) AMOLED Application Scenarios

High-end smartphones: AMOLED’s high contrast and color performance make it the preferred choice for high-end smartphones.

Wearable devices: AMOLED’s slim profile and low power consumption make it excellent in wearable devices such as smartwatches.

High-end TVs: AMOLED’s superior picture quality has gradually secured its place in the high-end TV market.

III. FQA

(I) Which is better suited for industrial applications: TFT or AMOLED?

TFT: Better suited for industrial applications due to its durability, long lifespan, and stability.

AMOLED: AMOLED also has unique advantages in high-end industrial equipment requiring high contrast and color performance.

(II) How to solve the AMOLED burn-in problem?

Live wallpapers: Avoid displaying static images for extended periods.

Screen savers: Use screen saver software to periodically move screen content.

(III) Which is more energy-efficient: TFT or AMOLED?

TFT: TFT power consumption is relatively stable when displaying white or bright content.

AMOLED: AMOLED consumes less power when displaying black or dark content. (IV) What is the lifespan of AMOLED?

AMOLED: Organic materials have a relatively short lifespan, especially at high brightness. However, with technological advancements, the lifespan of AMOLED is gradually improving.
