Description
Technical field
The present invention relates to field of display, more particularly to the computer display based on electronic ink screen screen protection side
Method and device.
Background technology
Electronic ink technologies (Electronic Paper Display, English abbreviation EPD) are shown by ambient light
New technology.Be packaged in the charged particle of black, white dichromatism in microcapsule structure by EPD Display Techniques system, by extra electric field control not
With the lifting moving of electric charge black and white particle (ink droplet), to show the display effect of monochrome, in the presence of electric field, black and white
Two kinds of different ink droplets can not stopped transport, and when the ink droplet of white rises to upper surface, all of ambient lighting is mapped to upper surface quilt
It is fully reflective, material is thus formed white state, that is, paper state.After electrode is exchanged, two kinds of ink droplet meetings of color
Exchange position, so white ink droplet can just be gone to following, and the ink droplet of black is arrived above, and light is by the ink droplet whole of black
Absorb, as a result result in black, be also formed white and black displays.In addition, can also have the state of mixing in upper surface, two kinds are not
The proportional mixing of same ink droplet, so can form black and white and have the different colours of gray-level.
The white and black displays effect of high reflectance, contrast high can be showed due to EPD technologies, while there is memory effect, works as handle
After extra electric field is cancelled, the currently presented display of instant playback, the content as shown in same printed paper.Due to tool
There is bistability, after power electrical field cancellation, image is retained into some months or several years still on EPD display screens.The skill
Art is similar to the typographical display effect of plain paper because reflective display can be realized by ambient light.So, with respect to self-luminous
The traditional display screen such as CRT, LED, LCD, OLED, EPD display screens are not easy to make one kopiopia, stare to damage for a long time and regard
Nethike embrane.Additionally, EPD display screens also have, and power consumption is low, energy saving advantage.
Currently, in addition to EPD technologies are applied in the handheld electronic reader device such as e-book, technology incites somebody to action
EPD display screens are used as computer display.But, the life-span of existing EPD computer displays has dynamic element in display
Picture when may be affected.For example, when EPD computer displays show the webpage with flash animation element, if
User does not change webpage in certain hour, and the quick change of flash animation element can cause ink droplet in the pixel of EPD display screens
Accelerated ageing, and then influence display quality and the life-span of whole EPD computer displays.Therefore, EPD computer displays are needed
Timely screen protection is carried out when computer is not operated.
Some computer displays of prior art can carry out screen protection operation.For example, CRT (cathode-rays
Kinescope) the imaging principle of display is mainly by filament heating negative electrode, and then emission of cathode electronics is accelerating the work of pole electric field
Under, line focus pole is polymerized to very thin electron beam, under anode high voltage effect, obtains huge energy, is gone with high speed
Bombardment phosphor powder layer.The target of these beam bombardments is exactly the three primary colors on fluorescent screen.Under the operating system of graphical interfaces,
Show that the color of screen display is varied, when user stops operating computer, screen display will be fixed on all the time
On same picture, i.e., electron beam bombards the same area of fluorescence coating for a long time, goes down for a long time, can be because of display screen fluorescence coating
Fatigue effect causes screen aging, and even kinescope is breakdown.Therefore, the screen protection method for CRT display screens is logical
Cross and show that the figure shows being continually changing make the fixing point on fluorescence coating not bombarded for a long time, so as to avoid the damage of screen
It is bad.
But, existing screen protection method is only applicable to CRT monitor and is not suitable for other types of display.
For liquid crystal display, i.e. LCD, the display of image is controlled by the switch of liquid crystal molecule, on-off times are more, damaged
Consumption is bigger.Therefore, when we stop operation to computer, if allowing on LCD and showing the screen protection program for moving repeatedly,
Liquid crystal molecule can be then set still to be on off state repeatedly, this will accelerate the service life of consumption LCD, easily go out being old for one's age, bad
The phenomenons such as point.Therefore, in the prior art, it is necessary to close screen protection program when using LCD as computer display.
For EPD computer displays, equally screen guarantor can not be carried out using the screen protection method of prior art
Shield, because the screen protection method of prior art needs carrying out making the image shown on screen fast when screen protection is operated
Speed change so that the ink droplet fast lifting in microcapsules, this screen protection method is even counted than not performing screen protection to EPD
The life-span of calculation machine display is more harmful to.
In the prior art, some E-book readers employ EPD display screens, but, these electronic readers are only used for
Reading electronic book, and cannot function as computer display and use.In addition, being shown as the EPD of the display screen of E-book reader
Screen need not show the fast-changing pictures such as such as flash animation of display adapter output as computer display, and
It is the static e-book picture for only needing to be stored according to user's operation display in E-book reader.Therefore, e-book is read
The EPD display screens for reading device will not be faced because picture fast refresh is so as to the problem for needing screen protection to increase the service life.
Although E-book reader has such as standby etc function, the purpose of such function is for power saving and prevents from missing
Touching, rather than in order in solving E-book reader non-existent fast-changing picture cause the ink droplet in pixel to accelerate
Aging problem.
Therefore, in the prior art, in the absence of the technology that screen life protection is carried out to EPD computer displays.
