Display panel, roller, manufacturing system and display device

Abstract

The invention discloses a display panel, a roller, a manufacturing system and a display device. The display panel comprises a driving substrate, a micro-cup base body, electrophoretic liquid and an electrode layer. The micro-cup base body comprises a plurality of micro-cup structures with openings facing the driving substrate; each micro-cup structure is filled with the electrophoretic liquid, andcharged particles are doped in the electrophoretic liquid; a plurality of grooves are formed on inner walls, opposite to the openings, in the micro-cup structures; the inner walls of the grooves arecambered surfaces, and the charged particles can make contact with the cambered surfaces with the grooves under the action of an electric field. The embodiment of the invention provides the display panel, the charged particles can be in contact with the cambered surfaces of the grooves under the action of the electric field, the charged particles are in surface contact with the cambered surfaces of the grooves, so that the contact area between the charged particles and the inner walls of the micro-cup structures is increased, more light rays can be directly emitted to the charged particles, the light energy loss of the light rays is reduced, the reflectivity of the display panel is improved, and the display effect and the contrast ratio of the display panel are improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a scroll wheel, a manufacturing system and a display device. Background technique [0002] Modern society is an era of information and display. More and more electronic products are springing up like mushrooms after a spring rain. Display technology serves the transmission of information. As people pursue more and more information acquisition methods, traditional newspapers and magazines have become Gradually replaced by electronic media, electronic media brings greater convenience to people living in the information society, especially the emergence of electronic paper displays, which overcomes the shortcomings of general electronic media such as high power consumption and inconvenient portability. [0003] The most common types of electronic paper displays are electrophoretic displays, and microcapsules and microcups are the most common types of electrophoreti...
