Detailed electronic paper is how it works oled module

E-wrap design with two components, the first one of course is the electronic ink, sometimes also referred to as "front panel"; another component of the relative is also known as the backplane, is mainly used to produce electronic ink page circuit assembly text or image. lcd module 
After the birth of the concept of electronic ink many years, engineers have developed a variety of manufacturing methods of electronic ink. E Ink was born in the seventies of last century, largely comprising a layer of tiny plastic beads of flexible plastic sheet, every little beads are packaged in tiny oil capsule, into the suspended state, so every little beads in Plastic plates are free to rotate. Each hemisphere beads with different colors and different charge. When the electric field is applied back on the beads, beads force rotation, thus forming a pattern of color. Of course, electronic ink is also limited, the brightness is relatively low, difficult to improve the resolution, and the lack of color. As the originator of electronic ink technology, electronic ink are still constantly improving in order to solve the above problems, but comes more and more manufacturers are optimistic about the prospects for electronic ink in recent years, the development of other improved design.
Electrophoretic electronic ink contains millions of microcapsules, each microcapsule diameter of about 100 microns, and the cross-sectional diameter of the hair rather our adult. Each of the main components of the microcapsule, transparent liquid, which carries a lot of white particles and negatively charged black particles positively charged. When the electrophoresis "Front Panel" negative field is applied, all of the white particles move to the top of the microcapsules, is then presented to the reader of a white point, and all of the black particles sink to the bottom of the microcapsules, in the eyes of the reader disappeared. When a positive electric field is applied, the black particles will move to the top of the white particles sink to the bottom, on the formation of black text or images. Electrophoretic electronic ink technology has its own characteristics, brightness and resolution targets, based on electronic ink technology it is more than good, but in one respect they are the same, but the disadvantage is the monochrome display technology, can not render colors.
Another drawback electrophoretic electronic ink is its low refresh rate, so that the technology is not suitable for displaying dynamic content such as animation and video. This is also due to the color particles in the electric field moves from one end of the microcapsules to the other side still needs to spend some time, the screen switches slowly caused. OLED Display
