TFT vs. OLED Screens: Which is Better?

In the field of display technology, TFT and OLED screens are two common technologies, each with unique characteristics and application scenarios. This article will detail the differences between these two screen technologies and discuss their advantages and disadvantages. We will also highlight the contributions of Hangzhou LEEHON Technology Co., Ltd. in the field of display technology.

I. Display Principles

TFT Screen
TFT (Thin Film Transistor) screens are a type of liquid crystal display technology that displays images by adjusting the light transmittance through a liquid crystal layer. TFT screens require a backlight to provide light; the liquid crystal itself does not emit light. Its structure includes a backlight, a liquid crystal layer, a polarizer, a color filter, and a TFT driving layer.

OLED Screen
OLED (Organic Light Emitting Diode) screens are a self-emissive technology where each pixel is an independently emitting organic material. OLED screens do not require a backlight, thus allowing them to be thinner and lighter. Its structure includes an organic light-emitting layer, anode and cathode electrodes, and an encapsulation layer.

OLED Screen

OLED (Organic Light Emitting Diode) screens are a self-emissive technology where each pixel is an independently emitting organic material. OLED screens do not require a backlight, thus allowing them to be thinner and lighter. Its structure includes an organic light-emitting layer, anode and cathode electrodes, and an encapsulation layer.

II. Display Performance

Contrast Ratio
TFT Screen: Contrast ratio is generally around 1000:1, which may result in insufficient depth when displaying dark or black images.

OLED Screen: Extremely high contrast ratio, reaching over 1,000,000:1, resulting in pure blacks.

Color Performance
TFT Screen: High color fidelity, but a relatively narrow color gamut, which may be slightly inferior when displaying vibrant colors.

OLED Screen: Wider color gamut, more vibrant colors, and a richer range of color gradations.

Viewing Angle
TFT Screen: Limited viewing angle. Although IPS technology has improved this issue, color shifts may still occur at extreme angles.

OLED Screen: Viewing angles approach 180°, maintaining good display quality from any angle.

Response Time
TFT Screen: Response time is approximately 5-20ms, which may result in blurring when displaying fast-moving images.

OLED Screen: Extremely fast response time, approximately 0.1ms, suitable for high refresh rate applications.

III. Power Consumption

TFT Screen: The backlight of a TFT screen is always on, resulting in higher overall power consumption. Power consumption is similar whether displaying black or white.

OLED Screen: Each pixel in an OLED screen emits its own light. Pixels are off when displaying black, resulting in extremely low power consumption. However, power consumption is higher when displaying white or bright colors.

IV. Lifespan

TFT Screen: TFT screens have a long lifespan, typically 50,000-100,000 hours, and there is no risk of burn-in.

OLED Screen: OLED screens have a relatively short lifespan, typically 10,000-30,000 hours, and there is a risk of burn-in.

V. Price

TFT Screen: TFT screens have a mature manufacturing process and lower cost, making them relatively affordable.

OLED Screen: OLED screens have a complex manufacturing process and higher cost, resulting in a relatively higher price.

VI. Application Scenarios

TFT Screen: TFT screens are widely used in various electronic devices, such as laptops, tablets, monitors, and automotive displays. Their high resolution and fast response time make them ideal for displaying dynamic images and videos.

OLED Screens

OLED screens are commonly used in high-end smartphones, smartwatches, wearable devices, and high-end TVs. Their high contrast ratio, wide color gamut, and slim design make them the preferred choice for users seeking the ultimate display experience.

VII. Contributions of Hangzhou LEEHON Technology Co., Ltd.

As a leading company in the display technology field, Hangzhou LEEHON Technology Co., Ltd. has been committed to the research and development and production of TFT and OLED screens. The company continuously innovates in TFT screen technology, achieving remarkable results, particularly in high resolution, low power consumption, and narrow bezel design.

VIII. Conclusion

TFT and OLED screens each have their advantages and disadvantages. TFT screens have advantages in color reproduction, lifespan, and cost, making them suitable for users who prioritize cost-effectiveness but don’t have high demands for display quality. OLED screens perform better in contrast ratio, color performance, viewing angle, and response time, making them suitable for users seeking the ultimate display effect and a slim design.
