What is the difference between OLED and LED

Abstract: With the continuous development of science and technology, the display technology is also constantly improving and updating. LED and OLED are two common display technologies that have their own advantages and disadvantages and are widely used in different fields. Although they both can emit light, there are actually quite a few differences between them. So what is the difference between LED and OLED? How should we choose?

1. The difference between LED and OLED

1. Differences in working principles

LED display uses the principle that electrons and holes in semiconductor materials recombine and release energy near the PN junction, and controls the brightness and color of LED light by controlling the current. LED displays require a backlight to display images.

OLED displays use thin films containing organic materials to generate and release energy in the form of excitons under the action of an electric field to emit light. OLEDs can emit light directly and do not require a backlight, so they have higher contrast ratios and faster response times.

2. Differences in display effects

The LED display needs a backlight to display images, so its display effect is affected by the backlight, and it is difficult to achieve true pure black. The OLED display can directly emit light without a backlight, so its black is more pure, the display effect is more realistic, the color is more saturated, and the contrast is higher.

3. Difference in viewing angle

The display effect of the LED display will change with the change of the viewing angle, while the display effect of the OLED display is basically unchanged under different viewing angles.

4. Differences in energy consumption

LED displays require higher voltage and current to emit light, so their energy consumption is higher; while OLED displaysscreen can emit light at low voltage and current, so their energy consumption is lower.

5. Differences in application fields

LED displays are mainly used in application scenarios that require large size, high brightness, and long life, such as indoor and outdoor billboards, stage backgrounds, stadiums and other fields.

OLED displays are mainly used in application scenarios that require high contrast, wide viewing angles, and low power consumption, such as consumer electronics such as mobile phones, tablet computers, and TVs.

2. Comparison of the advantages of led and oled

1. Advantages of LED display

High brightness: LED display has high brightness, suitable for outdoor use;

Long life: The LED display has a long life and can be used for many years;

Low power consumption: Compared with other display technologies, LED displays have lower power consumption;

The display effect is limited by the angle: the display effect of the LED display will be limited under different angles.

2. Advantages of OLED display

High contrast ratio: The black of the OLED display is very pure, the color saturation is high, and the contrast ratio is higher;

Wider viewing angle: OLED display can show the same display effect under different angles;

Faster response time: The response time of the OLED display is faster, and the dynamic image display effect is better;

Uniform display brightness: OLED display can display brightness evenly;

Display colors more accurately: OLED displays are capable of accurately representing various colors.

3. How to choose led or oled screen?

All things considered, you can choose the screen type that suits you according to your needs. If you need a screen with high brightness and contrast for outdoor use, then an LED screen may be more suitable; if you need to use it indoors and require higher picture quality and color saturation, then an OLED screen may be more suitable.

To sum up, LED and OLED are two different display technologies, but no matter which display technology is constantly developing and updating, future display technologies will continue to emerge. I believe that in the near future, we will see the emergence of more advanced display technologies.

It is worth mentioning that Chenghao Display has been focusing on OLED research and development and production for a long time. It has accumulated a lot of OLED technology and experience, and has also developed its own OLED products. If you are interested in this, welcome to contact us. connect!
