AMOLED and PMOLED display
PMOLED is a passive matrix OLED. PMOLED cannot be made into a large size because it requires direct current drive, generally under 3 inches. AMOLED stands for Active Matrix Organic Light Emitting Diode, which is hailed as the next generation of display technology because of its thinness and high performance.
what is PMOLED display?
PMOLED is the abbreviation of Passive matrix OLED, which uses cathode and anode to form a network, and the position where the cathode and anode cross will be lit up by continuous scanning with voltage, thus creating an image.
Is PMOLED better than AMOLED?
PMOLED is a simple display, usually monochrome low resolution. AMOLED is complex to produce, with ultra-high resolution and perfect optical indicators, AMOLED performance is better than PMOLED, but the cost is also several times higher
what is AMOLED display?
AMOLED is to use TFT to control each pixel, using current to drive each pixel individually, the process is complex but can achieve very high resolution, known as the next generation of display technology
What is the difference between the structure of OLED and LCD？
The structure of TFT LCD is very complicated, TFT LCD needs backlight as light source, two polarizers are needed to adjust the polarization direction of light, and the thickness of the whole display module is about 2~3mm. As LCD needs to maintain a certain thickness to work properly, so LCD can only bend a small curvature.
OLED for self-lighting technology, no other light source so you can do very thin, if you use a flexible substrate can also be bent, bending radius can be achieved 5mm. and has ultra-high resolution, ultra-high color gamut and contrast ratio
What is electroluminescence？
Electroluminescence (EL) refers to the phenomenon that luminescent material is excited by current under the action of electric field to glow. It is a luminescence process that converts electric energy directly into light energy. There are many kinds of solid materials that can produce electroluminescence, mainly divided into inorganic compound semiconductor materials and organic compound semiconductor materials. The development rate of inorganic compound semiconductor materials is higher than that of organic compound semiconductor materials.
p-n Junction inorganic semiconductor light-emitting diodes have been greatly developed, achieving coverage of the visible spectrum and emitting more light efficiency than incandescent bulbs. Inorganic LED devices have many advantages, such as strong structure, low driving power, long service life, high efficiency, strong stability and so on, and have been widely used. However, the production cost of inorganic LED devices is high, processing is difficult, low efficiency, light color is not easy to adjust. Organic compound semiconductors have been slow to develop, so high-end OLED (organic Light-Emitting Diode) displays remain highly priced
