Description
Technical field
The present invention relates to the display technique field, relate in particular to display device and display interface method for refreshing thereof, display interface method for refreshing and device.
Background technology
Along with the arriving of information age, because the increase in demand that people and external information are linked up, the display device with the function of diffusing information has become one of indispensable electronic product of modern.(cathode ray tube, CRT) display is developed to now more frivolous LCD (liquid crystal display LCD), has been widely used in communication, information and consumption electronic product etc. display device by initial cathode-ray tube (CRT).Yet because LCD need continue to provide power supply for operation, like this, the waste electric energy is so more the display technique of the electrophoretic display device (EPD) of power saving (Electrophoretic display) is developed.
Utilize computing machine to handle and preserve great mass of data, yet, compare with paper, because volume, weight and the operation etc. of computing machine are all read not as good as information being recorded in being convenient for carrying with convenient of paper printing matter, therefore in this case, electric paper display (E-paper display based on electrophoretic techniques, EPD) arise at the historic moment, the thickness of electric paper display can be suitable with plain paper, can duplicate the display property of paper and can reuse, and electric paper display can show dynamic menu.Electronic Paper more and more is subjected to the welcome in market with the soft display effect of its lower energy resource consumption and similar paper and the prospect expection that can substitute paper.The static state that its outstanding retention performance is very suitable for text reading one class shows product.
Study the more electric paper display that is based on electrophoretic techniques at present, electrophoresis is meant that charged particle moves in the electric field that applies, its ultimate principle is: there is charged particle in the electrophoresis liquid the inside, these charged particles can move under effect of electric field, and can reflect surround lighting, be received by human eye as display image as the paper; In the picture conversion stage, according to the electrophoresis liquid two ends alive size and time can control the position of charged corpuscle at place, electrophoresis liquid the inside, show thereby control the catoptrical strong and weak GTG of realizing; Keep the stage at picture, make electrophoresis liquid two ends equipotential, thereby make charged corpuscle can keep tableaux with low energy consumption, realize that tableaux shows in holding position, electrophoresis liquid the inside.
Yet adopt the overall situation (full frame) to refresh to the renewal of picture on the EPD display screen in the prior art, if the size of screen is 600 * 800, each data that transmit must be 600 * 800 pixel datas, and behind the transmission display command, the EPD controller will show 600 * 800 pixel values; When being the picture on the update displayed screen, when on display screen, having only the part picture to change, still whole image is upgraded again, since the refresh rate of EPD slow (refresh rate is about 700ms) in the prior art, the phenomenon that screen can occur dodging when adopting the overall situation to refresh.
Many patents about electric paper display and driving method thereof are arranged in the prior art, and for example application number is 200880000725.3 Chinese patent application, yet does not all solve the shortcoming of above-described prior art.
