OLED display is a term commonly seen in technology products. So what sets apart a screen equipped with this feature from other TV models, and what advantages does it offer to consumers? Let's explore this technology further with Mytour Blog!
What is OLED display?
OLED display (short for Organic Light Emitting Diodes) is a type of organic light-emitting diode (LED). The emissive electroluminescent layer of the diode consists of a film of organic compounds that emit light in response to an electric current.

OLED displays are composed of four separate components serving different purposes:
- Anode: This is the empty region at the end of the display, accumulating positive charge when a current runs through.
- Cathode: An empty region above serving to hold negative charge when a current runs through.
- Organic conducting layer: This component lies between the two electrodes. The conducting layer consists of two main components playing separate roles: the conducting layer (constructed from high molecular weight organic molecules to transmit 'electron holes' from the positive electrode) and the light-emitting layer (responsible for transporting electrons from the negative electrode).
- Substrate: Often made of plastic or glass, it's tasked with supporting the components of the OLED.

Like many other types of displays, alongside fantastic advantages, OLED displays also possess some minor drawbacks. You can refer to the following overview to support your purchasing decision.
Advantages:
OLED displays have the ability to showcase images with high contrast and brightness, creating deep blacks, providing wider viewing angles, and occupying less space compared to traditional displays; thereby allowing viewers to enjoy vivid, stunning images. Furthermore, this display offers wider viewing angles while consuming relatively low power and maintaining good image quality.
Drawbacks:
In addition to its outstanding advantages over other technologies, OLED panels have some drawbacks to consider, including high cost, susceptibility to low humidity, and not being highly durable. When exposed to water or low-humidity environments, this display has a relatively high probability of damage.
Review of OLED display
To provide users with a clearer understanding of products using OLED technology, Mytour will introduce some of its current outstanding features:
Image Quality
OLED integrates various color filters, contributing to deeper blacks and wider color gamut. The absence of a backlight will result in better contrast (the difference between the brightest and darkest points on the screen).
Power Consumption
OLED displays do not require the creation of LED backlighting using any electrical current or circuitry, so they consume very little power. Additionally, completely closing the shutter of the pixels and backlight (although it still exists but is generally blocked) helps the OLED panel achieve deeper black colors. In this case, the display will completely disable the pixels to produce black, maximizing energy savings in the process.
Viewing Angle
Products employing OLED technology provide wide viewing angles (Source: Internet)Compared to conventional LED displays, OLED displays offer wider viewing angles of nearly 90 degrees on many substrates without compromising image clarity and sharpness.
Durability
Manufacturers have replaced the fragile and bulky glass substrate of OLED panels with a lighter and more robust plastic substrate, thereby eliminating the backlight and shutter layers. Additionally, the device has been uniquely developed with a curved surface. OLED film also has a significantly wider operating temperature range compared to traditional LED displays.
Comparison of OLED, LCD, and AMOLED displays
In addition to OLED displays, the current market also offers two other types: LCD and AMOLED. Let's take a look at the comparison table of these 3 types of displays to evaluate which criteria are suitable for you.
| Đặc điểm so sánh | OLED | LCD | AMOLED |
| Nguyên lý hoạt động | Được trang bị tấm điốt hữu cơ hoạt động theo cơ chế màn hình sẽ tự động sáng lên khi có dòng điện chạy qua. | Phát sáng gián tiếp bằng đèn nền và các hạt tinh thể lỏng | Cấu tạo nguyên lý khá giống OLED nhưng nó được trang bị hệ thống Active Matrix (ma trận chủ động). |
| Độ dày | Mỏng | Dày | Siêu mỏng |
| Độ sâu màu đen | Hiển thị màu đen sâu | Xuất hiện hiện tượng hở sáng | Hiển thị màu đen sâu |
| Góc nhìn | Độ sắc nét và chất lượng màu của hình ảnh vẫn vẹn nguyên kể cả những góc nhìn nghiêng trên 40 độ. | Chuyển đổi góc nhìn từ 40 độ trở lên sẽ tạo ra sự khác biệt. | Góc nhìn màn hình cực rộng và độ sắc nét tuyệt vời. |
| Màu sắc hiển thị | Màu sắc sống động hơn màu thật. | Màu sắc chân thật | Phổ màu rộng và sặc sỡ |
| Tuổi thọ | Từ 20000 – 50000 giờ | Từ 40000 – 10000 giờ | Khoảng vài năm |
| Lượng điện năng tiêu thụ | Ít | Nhiều | Ít ở mức tối đa |

Devices Integrated with OLED Display
Let's take a look at 3 standout devices featuring OLED displays on the market below!
Television
We can see OLED displays appearing quite frequently in the product lines of the most prominent OLED TV manufacturers today, including LG, Sony, and Panasonic. OLED TVs feature an OLED panel as thin as 2.57mm, eliminating the need for backlighting. Therefore, their designs are often lighter and thinner than QLED TV models.
Laptop
This display is not only integrated into TVs but has also appeared quite frequently in laptops. Many laptop brands have implemented OLED technology into their products to best meet customer needs.
Mobile Phone
OLED panels are no longer unfamiliar as they are widely used in many markets, most notably in mobile phones, tablets, digital cameras, and VR headsets. Samsung Display (a subsidiary of the Samsung Group) specializes in manufacturing mobile devices equipped with this display, and the company has incorporated this technology into all of its flagship products, most recently the Galaxy S8, S8 Plus, and Note 8.

OLED displays are relatively high-priced, so not everyone is willing to pay for devices integrated with this type of display. The high price of OLED panels is also because they are made from organic materials, which often have low productivity, especially for large screens. Therefore, the prices of these products when released to the market are quite high.
Conclusion
This article has shared all the relevant information about OLED displays that readers are interested in. Mytour hopes that through this, you will recognize the outstanding features you are looking for to support your selection process for your TV, phone, and laptop screens!
