Description
Technical Field
The invention relates to the technical field of display equipment, in particular to a 64-level gray scale pixel structure and a display medium.
Background
The two-state development means that the two states can be presented, such as monochrome ink printing, any ink drop is the same black, and the visual effect of gray scale is generated by adjusting the distribution density of the ink drop on the paper surface. Similarly, the transparent/opaque display is a two-state image display, and the visual effect of gray scale display can be realized by using similar principles.
However, if the above method is used to realize n-order gray scale (e.g. 64-order gray scale), n-type droplet distribution density, e.g. 64-type droplet distribution density, needs to be made in a unit area of the imaging medium. For a density distribution near full black and white, i.e., a gray level "very close to white" or "very close to black", a fine texture is created (e.g., when the media substrate is "white", each droplet as "black" must be very fine and very sparsely distributed to achieve a gray level very close to full white).
The generation of the microstructure is not favorable for the adhesion of the microstructure and the medium substrate, and the microstructure is easy to fall off and wear and is expressed as macro pattern gray scale deletion, defect and the like. In addition, more sophisticated and expensive equipment is required to produce fine and delicate structures, and in practical applications, it is difficult to generate more expressive multi-gray scale images due to scarcity of high-end equipment and high application cost.
