Entering the World of OLED

OLED is a cutting-edge display technology with many advantages. Its display technology is divided into two categories: PM-OLED and AM-OLED, each with different characteristics and application scopes.

   An Organic Light-Emitting Diode (OLED) is a semiconductor device based on organic materials. It is made by placing a series of organic thin films between two conductors. When electrical current is applied, a bright light is emitted. It has a number of advantages. For example,  the property of self-emitting makes it colorful, high contrast and can present realistic and clear picture. OLED screens are so thin and soft that can be bent, folded and be used to make a variety of innovative products. Meanwhile, they consume less energy that can effectively save power.

   An OLED display can be driven with a AMOLED (active-matrix) or PMOLED (passive-matrix) control scheme. The AMOLED has longer lifetime, and the picture quality is high, full color, high contrast, and high efficiency, but more expensive and complicated. Therefore, it is suitable for full color OLED display products with large size, high resolution and high information capacity. PMOLED has a shorter pixel lifetime and limited resolution, but it is more suitable for simple and small-sized display devices because of its low cost and simple manufacturing process.
