LCD screens and OLED screens are currently the mainstream display technologies, but there are significant differences between them. Shenzhen Full View Electronics will delve into the differences between OLED screens and LCD screens, and compare their advantages and disadvantages.

The difference between OLED screens and LCD screens

OLED screen (Organic Light Emitting Diode)

OLED screen is an organic light-emitting diode technology, characterized by each pixel being composed of light-emitting diodes. When current passes through a pixel, it emits light. OLED screens do not require backlighting and have the characteristic of self illumination. In addition, OLED screens can achieve higher contrast and wider viewing angles, while also having faster response times.

LCD screen (Liquid Crystal Display)

LCD screen is a type of liquid crystal display technology, characterized by each pixel being controlled by a liquid crystal unit. LCD screens require a backlight source to illuminate pixels. The LCD unit controls the degree of light transmission by adjusting the transparency, thereby achieving image display. LCD screens typically use LED backlighting, known as LED LCD screens.

Comparison between LCD screens and OLED screens

1. Contrast

OLED screen: OLED screens can achieve higher contrast, with each pixel self illuminating. When black is displayed, pixels can be completely turned off, achieving infinite contrast.

LCD screen: The contrast of an LCD screen is affected by the backlight, which cannot reach the contrast level of an OLED screen. Especially when black is displayed, the backlight cannot be completely turned off, resulting in a "gray" situation.

2. Perspective

OLED screen: OLED screens have a wider perspective, and even when viewed from the side, images can still remain clear and bright without color distortion.

LCD screen: The viewing angle of the LCD screen is relatively narrow, and when viewed from the side, there may be color changes or distortion in the image.

3. Response speed

OLED screen: OLED screens have faster response speed and can achieve smoother dynamic effects, suitable for watching high-speed videos and playing games and other scenes.

LCD screen: The response speed of LCD screen is relatively slow, and there may be situations where the dynamic effect is not smooth enough, especially when displaying rapidly moving images.

4. Energy consumption

OLED screen: When displaying black, OLED screens can turn off pixels and consume almost no energy, resulting in lower energy consumption when displaying images with dark tones.

LCD screen: LCD screens require backlighting to illuminate pixels, resulting in high energy consumption. Regardless of the color displayed, the energy consumption remains the same.

5. Life expectancy

OLED screen: Due to the decay of organic luminescent materials in OLED screens over time, the lifespan of OLED screens is relatively short and may experience screen burning.

LCD screen: LCD screens have a longer lifespan and are less prone to screen burning, but the LCD unit may experience pixel failures caused by aging.

How to choose?

Choosing an OLED screen: If you focus on display effects and want to achieve higher contrast, wider viewing angle, and faster response speed, then an OLED screen may be more suitable for you.

Choosing an LCD screen: If you focus on cost and durability, and want to achieve a longer lifespan and stable display effect, then an LCD screen may be more suitable for you.

summary

OLED screens and LCD screens are currently the mainstream display technologies, each with its own advantages and disadvantages. When choosing, it is necessary to consider comprehensively based on one's own needs and preferences. I hope this article can help you better understand and choose OLED screens and LCD screens.
