LED and OLED screens have the following main differences:

Luminous principle:

[LED screen](https://sostron.com/product?category=2): LED screens use a backlight, usually LED beads or fluorescent tubes, to illuminate the screen. This backlight illuminates an LCD screen or other type of panel, allowing it to display content. Therefore, an LED screen is actually a combination of a liquid crystal display (LCD) and an LED backlight. Liquid crystal is used to control the transmission and blocking of light, while LED backlight provides brightness.

OLED screen: OLED screen is self-luminous, and each of its pixels is a small organic light-emitting diode. Each pixel can be illuminated or turned off independently, without the need for a backlight. This means that OLED screens can achieve pixel-level precise control, higher contrast and more vivid colors.

Contrast and Color:

OLED screens generally have higher contrast ratios because they can achieve true blacks when turned off completely. Compared with LED screens, OLED screens have deeper blacks, brighter whites, and richer and fuller colors. This makes OLED screens better in terms of viewing experience, especially in low-light conditions.

life:

The organic materials in OLED screens can become damaged over time, causing the screen to suffer from image retention or burn-in issues. LED screens don’t have this problem and are more durable.

cost:

OLED screens are relatively expensive to manufacture, so they're generally more expensive. LED screens are more cost competitive.

Advantages of LED display:

1. Mature and stable technology

LED technology has been developing for decades. From LED chips to lamp bead packaging to LED displays, China has a complete industrial chain. The technology is mature and the products are very stable. From products for outdoor applications to indoor small-pitch products, there are Many specifications.

2. Good splicing integrity

One of the great advantages of LED displays is that there are no splicing marks after splicing. The integrity of the entire screen is very good, so when displaying the picture, the full-screen display effect is good and there is no visual impact. However, 0LED displays will have splicing gaps, just like LCD Same as splicing.

3. Waterproof and sunproof, supports outdoor applications

Another advantage of LED display is that it can be used for outdoor display, because it supports waterproof, sunproof and moisture-proof features, and it is also very bright. Even if the sun shines directly on the screen, it can still display normally.

4. Low price and wide range of options

The cost of LED displays is more advantageous than OLED displays, so in terms of price, LED displays are more cost-effective, and their specifications range from P20 to P1.2. They have many specifications and a wide range of options. [Do you want to know about the top 9 LED display manufacturers in Africa? ](https://sostron.com/news/5789)

Advantages of OLED display:

1. Better picture quality

In terms of the fineness, softness, and contrast of image display, OLED displays have great advantages. They are even better than LCD screens.

2. High definition

0LED display has high resolution and can achieve 4K display. The resolution is higher and the clarity is better. It is especially suitable for use at close range. This is one of its major advantages.

3. Energy saving

OLED display has very low power consumption because it is self-luminous and does not require a backlight, so it is very energy-saving and environmentally friendly. If it needs to be turned on continuously for a long time, it will save a lot of power and directly reduce the cost of use.

4. Suitable for large-size curved screens

Since OLED screens are thin, lightweight and easier to bend, large-size curved screens are mostly OLED screens.
