Description
Technical field
The invention belongs to the electronic paper technology field, be specifically related to the color electric paper of three-dimensional colour mixture.
Background technology
The overall development process of Electronic Paper can be summarized and be divided into three developing stage, and the phase one has storage property, utilizes surround lighting to show, energy saving, the friendly white and black displays of flicker free vision are main application fields with electronic reader and e-book etc.; Subordinate phase can realize multicolor displaying, but can't satisfy the requirement that video shows, can be applied to magazine, advertisement, and the application market scope is further widened; Phase III is can reach video to show the response speed of demand and the color rendering that full color shows.Wherein subordinate phase is the key that can the Electronic Paper product finally occupy the reader leading position, thereby color electric paper is the R&D direction of numerous manufacturers, but up to now, does not still have ripe scheme to move towards market.
The technical scheme of existing color electric paper has a variety of, and more influential color mode is cholesteric, optical filter type, colour particles type and Electrowetting type scheme.In color electric paper, that the display effect quality depends on is black, white, the situation of the reflection strength of five kinds of states of three primary colours.In the existing display mode, have and directly utilize KPT Scatter or liquid, solid-state surface reflection, also utilize birefringent selection reflection or scattering.Up to the present, be that which kind of display mode all can't obtain desirable colored show state simultaneously, main restriction is chroma-luminance and color reproduction scope.
Colored cholesteryl liquid crystal Electronic Paper adopts the lamination demonstration to reach full color demonstration purpose; The principle of this technical scheme is following: cholesteric liquid crystal material has unique light reflection selectivity characteristic; The ratio of cholesteryl liquid crystal is different; Select the wavelength of reflecting light also different, can realize the light of reflect red, green, blue three kinds of wavelength through selecting suitable material, these three kinds of light realize that as the three primary colours of additive color mixing full color shows.The basic structure of cholesteryl liquid crystal Electronic Paper pixel is sandwich construction, and each pixel is piled up formation by 3 layers that can reflect " blue-green-red " respectively, and indigo plant-green-red three kinds of liquid crystal materials not overlapping mutually being placed on realizing the color stack in one deck spaced apart also arranged.Bottom is the black light absorption layer, and each reflection horizon (or unit) to the corresponding change of reflectivity of 3 kinds of primary lights in the surround lighting, the primary lights of 3 kinds of suitable intensity that reflected just can be mixed into required certain color according to the colour mixture principle, thereby realize colored the demonstration.Its advantage is that color effect brightness is better, shortcoming be deceive, the display effect of white state is poor, particularly white states is gloomy.
Use the color electric paper of optical filter mode to be easy to technically realize; But color filter can reduce light reflectivity or display brightness; Become a display pixel must not have overlapping with a plurality of color sub-pixel combinations simultaneously; Reduced the pixel quantity of unit area, this scheme is that cost realizes colored the demonstration to reduce brightness and resolution.TFT is had the display mode of backlight,, can realize high brightness and high resolving power, obtain excellent display effect through improving brightness backlight.For the Electronic Paper pattern, utilize surround lighting to reach electronics and show that its tone heights relies on the reflectivity of Electronic Paper, this is colored filter application limit place.Therefore, many manufacturers and research institution all have the reflected colours optical property, need not the electronic paper technology that colored filter just can be realized the colour demonstration being devoted to develop pixel self.
Do not need the technology of colored filter that cholesteryl liquid crystal Electronic Paper, horizontal electrophoretic techniques, inverted emulsion electrophoretic techniques, electrowetting technology, interferometry modulation technique, photonic crystal demonstration, electrochromic display etc. are arranged.Horizontal electrophoretic techniques and inverted emulsion electrophoretic techniques, these two kinds of EPD can utilize the mechanism of its pixel self reflect color light to realize colored the demonstration.Horizontal electrophoretic display technology, characteristics such as the high brightness and the high grade of transparency make IP-EPD can adopt multiple mode to realize colored the demonstration.These two kinds of electrophoretic techniquess all are to adopt the method for sub-pixel stack to realize colored the demonstration.The pixel of the wetting demonstration of electricity is a kind of sandwich construction that is made up of water, pigment oil, hydrophobic material, transparency electrode, white substrate etc.When not having impressed voltage, pigment oil has formed a stable flat oil film on the hydrophobic material surface, but reflect ambient light and make pixel show a colored point; When on-load voltage on electrode; The electric field that it produced descends the hydrophobicity of hydrophobic material, and the water on upper strata can contact with the hydrophobic material surface as much as possible, thereby causes pigment oil to be pushed on one side; Following white substrate reveals, and makes pixel be shown as white point.Utilize the reflection characteristic of EWD, will adopt blue-green (Cyan), carmetta (Magenta), yellow (Yellow) 3 kinds of primary colours EWD display layer to pile up, promptly can utilize its CMY primary lights that reflect respectively to realize colored the demonstration with the substractive color mixing mode to colorama.The power consumption of EWD is very low, but does not possess the zero-power bistable characteristic.The interferometry modulation technique is similar to the principle of the Fabry Perot etalon (Fabry-Perot etalon) in the optics, and its major defect is to make to have very difficulty of two adjustable reflectings surface of nanoscale distance, and range deviation will cause contrast to descend.The challenge of particularly in one several inches Electronic Paper display surface, making millions of zero defect display units is huge.Interferometry modulation technique color sub-pixel realizes that colored method realizes through RGB three primary colours mode arranged side by side.Photonic crystal shows that (Photonic Crystal Display, PCD) technology is that the wavelength that powers up the single pixel in back changes and can cover the overall optical spectral limit.In existing color display method, show with the dual mode realization is colored side by side through the lamination of three primary colours.This dual mode can be produced desirable Electronic Paper theoretically, but in fact the desired target of effect distance of color electric paper also there is a big difference.Chief reason is that the performance of three primary colours is unbalanced, no matter be additive color mixing or substractive color mixing to present sub-pixel structure, all can't utilize and loyal reproduction coloured light is efficient.
