With the rapid development of technology, mobile phone screen technology is also constantly upgrading. Among the many screen technologies, OLED and AMOLED have attracted much attention. So, what exactly are the differences between these two, and which is better? Today, we will take a comparative journey between OLED and AMOLED, take you to appreciate their respective advantages and disadvantages, and create an exclusive vision for you.
1. The difference between OLED and AMOLED
1.Rationale:OLED (Organic Light Emitting Diode) is a solid-state organic semiconductor material. When an electric current is passed, the organic material emits light. AMOLED (Active-Matrix Organic Light Emitting Diode) is an active matrix organic light-emitting diode, which uses a series of organic thin film materials to form a luminous effect between the positive and negative electrodes.
2.Differences in strengths:AMOLED has a faster response time, higher contrast ratio, and a wider viewing angle. OLEDs can achieve thinner thickness, lower power consumption, and unique flexibility.
3.Materials & Construction:OLED uses a very thin coating of organic materials and a glass substrate. AMOLED, on the other hand, uses a series of organic thin film materials between the positive and negative electrodes.
Second, the practical application case of OLED and AMOLED
1.Mobile phone field: At present, the mainstream high-end mobile phones on the market basically use AMOLED screens, such as Apple, Samsung, Huawei and other brands. OLED screens are more common in low-to-mid-range phones.
2.TV: OLED TVs have gradually become the mainstream choice in the high-end market, with their self-illuminating characteristics, they can achieve the ultimate black effect and a wide color gamut. AMOLED TVs have a relatively small market share due to their high cost.
3.Automotive display: OLED and AMOLED screens are used in the field of automotive display. Due to the high contrast and fast response characteristics of AMOLED screen, it performs well in navigation, instrument cluster and other scenarios. OLED screens are popular in in-vehicle infotainment systems due to their thin, light, and power-saving characteristics.
3. Analysis of the advantages and disadvantages of OLED and AMOLED
1.OLED Pros:
Thinner thicknesses can be achieved without the need for backlighting;
The colors are vivid and the display effect is excellent;
Low power consumption, which is conducive to prolonging the battery life of the device;
Flexible features, can make curved screens and other innovative designs.
OLED Cons:
The process is relatively immature, and the production cost is high;
It is easy to cause screen burning and affect the service life;
It is more harmful to the eyes.
2.AMOLED Pros:
The response speed is fast and the display effect is excellent;
Low power consumption, which is conducive to energy saving;
With the development of technology, the problem of short life has been gradually improved.
AMOLED Cons:
The cost is high, and the production cost needs to be reduced;
The AMOLED materials and quality used by some manufacturers are uneven.
Fourth, purchase suggestions
When shopping for electronic products such as mobile phones and TVs, you can choose according to your needs and budget. If you pursue the ultimate display effect, fast response and high-end quality, you can choose AMOLED screen; If you're more interested in thin and light design, power-saving features, and flexibility, then an OLED screen may be more suitable for you.
In short, OLED and AMOLED screens have their own advantages and disadvantages, and they need to be considered comprehensively according to personal needs and budget. Hopefully, this article will provide you with a useful reference and help you create your own vision.
