                                            The difference of amoled and pmoled

OLED display technology has the characteristics of self-luminous, wide viewing angle, high contrast, low power consumption, high reaction rate, light weight, thin thickness, full color, simple process, and is a representative of cutting-edge technology.


According to the driving method, OLED can be divided into active drive (AMOLED) and passive drive (PMOLED). Each pixel of AMOLED is equipped with a TFT (Thin Film Transistor) with a switch. The driving mode of the AMOLED is easier to achieve high brightness, high resolution, high color performance, and low power consumption. Such panels are widely used in consumer electronics products; PMOLED has a simple structure and easy process. It can effectively reduce manufacturing costs and response speed. It has great development potential in displaying simple micro devices. However, PMOLEDs will have large power consumption and long life if they are to be used for larger size applications. The problem of reduction is not suitable for large-size and high-resolution panels, and the current product size is limited to about 5 inches.


In the past two years, due to the slimness, power saving, ease of development of soft applications, and the ability to adapt to a variety of application scenarios, AMOLED displays have attracted widespread attention both inside and outside the industry. Compared with the investment of AMOLED or the transformation of a single production line that requires more than 10 billion investment, the investment of a single PMOLED production line is only about 200 million yuan. PMOLED technology is very advantageous in terms of small size and even small size. Under the premise of ensuring product quality, PMOLED can achieve the size that AMOLED can not achieve, or it can achieve the same size as AMOLED price, and its investment. Cost-effectiveness cannot be ignored.
