1. Theoretically, it is superior to the traditional LCD screen in terms of thickness, viewing angle, energy consumption and color reproduction ability. However, these advantages are useless. Digital products have belief bonus, and the performance of amoled screen has not been improved to earth-shaking level. Better screens alone can't grab Apple's market share.
2. Disadvantages are short service life and difficult manufacture. However, these shortcomings cannot be called shortcomings. I believe that few people use their mobile phones until the end of their lives before replacing them with new ones. As long as the screen life is longer than the product replacement cycle, no one cares about the screen life limit; Speaking of production difficulty, Samsung's screen is made by itself, and the cost can be controlled to a minimum. Amoled screens are also used in high-end products, so there is no need to fight price wars.
This is Samsung's patented technology, and only Samsung's high-end products and a few authorized products use amoled screens.
