Description
Technical field
The present invention relates to a kind of display technology field, more particularly to a kind of microcapsules liquid crystal and micro- glue comprising conductive material
Cyst fluid crystal device, to realize black and white or colored display.
Background technology
Whether the CRT disappeared is on the verge of, still the LCD of main flow now, inherently belongs to traditional rigid display.With
Common rigid display is compared, and flexible display has many advantages, such as：Impact resistance, shock resistance is stronger；Lightweight, volume
It is small, carry and more facilitate；Using the roll-to-roll process similar to newspaper printing technique, cost is cheaper etc..It is main at present
Flexible display material is broadly divided into three kinds：Electronic Paper (or flexible electrophoresis showed), flexibility OLED and flexible liquid crystal etc., wherein again
It is the most extensive with Electronic Paper.
General marketplace expected from Flexible Displays, which is applied, to be included substituting newspaper, books and paper in magazine, point of sale (POS) end
End equipment, indoor and outdoor sign board, smart card and retail shelf label.Potentiality of this technology in automobile market are especially huge
Greatly, it is related to windshield, instrument board, bumper bar label, upholstery, GPS and other information amusement function.With wearable electricity
Sub- equipment is increasingly pursued, and market will further expand to the demand of flexible display screen, the commercialization road of flexible display screen
Also it will stride forward step by step.
Flexible Displays can provide polynary external form and design, and frivolous, impact-resistant characteristic be then applied to mobile phone,
In the portable product such as PDA or notebook computer.In addition, exploitation flexible display is another important factor is that its technique can
Roll-to-Roll Manufacturing can be converted into by Sheet-fed Batch Processing, it is meant that display
Manufacturing cost can be greatly reduced.With reference to the advantage to sheet properties in similar and engineering properties and the renewable letter of digital and electronic media
The characteristic of breath, adds the advantage of manufacturing cost, and flexible display very likely replaces current flat-panel screens, and in emerging city
Field obtains business opportunity.
Flexible display based on bi-stable electronic paper technology is the developing direction of more practical.Bistable state is a kind of
Image (data) can be made in the case where no applied voltage drives, the stabilization " memory effect " that can still keep.Tradition
Display, regardless of whether using backlight, be required for power supply update picture and it is stable keep picture, therefore consumed
Electric power is excessive.And the Electronic Paper with bistable state feature, when an image is written into Electronic Paper, it is not necessary to input extra electricity again
Source, this image can be retained always, and additional power supply only need to be just inputted when image does and switched, therefore can be with power and energy saving.And
And, Electronic Paper is shown using ambient light, compared to active active display or the LCD of use backlight, more power saving.
One of the reason for flexible display is not yet popularized comprehensively is that the special-purpose member for constituting flexiblesystem is complete not enough.
The development of Flexible Displays is related to developing material, processing procedure improve, process apparatus is changed, new display pattern is developed, yield is controlled etc.
Problem.Bi-stable electronic paper technology is related to the problems such as bistable material exploitation, processing procedure improvement.
For example, in the patent CN85104765A of application in 1985, the quick microcapsules system of crystalline emulsion is proposed earliest
Method, is mainly characterized by using double-layer encapsulation liquid crystal with two kinds of wall materials；In manufacturing process, by the inside and outside wall of liquid crystal nuclear capsule material
Material, alcohol, water are made into by a certain percentage to dissolve each other and insoluble mixture, and carries out cyst wall with heating cure method simultaneously in its emulsification
Cure process.It is that the color-changing liquid crystal with notable temperature effect and optical characteristics further expands to make liquid crystal microcapsule with the present invention
Its big application provides favourable condition.
Bi-stable electronic paper technology mainly includes particle mobile model electronic paper technology and bistable liquid crystal Display Technique two is big
Class.The main flow of particle mobile model electronic paper technology is Microencapsulated Electrophoretic Display Technology, but the particle translational speed in microcapsules
It is relatively slow, it have impact on the page turning switch speed of the Electronic Paper based on Microencapsulated Electrophoretic Display Technology.Liquid crystal molecule is than in microcapsules
Particle is small, can be with quick rotation, so it is development bi-stable electronic paper to develop bistable liquid crystal microcapsule under electric field action
One important directions of technology.
