Description

显示装置、显示界面的刷新方法及装置 Display means for displaying an interface refresh method and apparatus

技术领域 FIELD

[0001] 本发明涉及显示技术领域,尤其涉及显示装置及其显示界面刷新方法,显示界面刷新方法及装置。 [0001] The present invention relates to display technology, and particularly relates to a display device and a method of refreshing a display interface, the display interface means and refresh method.

背景技术 Background technique

[0002] 随着信息时代的来临,由于人们与外界信息沟通的需求增加,具有传播信息功能的显示装置已成为现代人不可或缺的电子产品之一。 [0002] With the advent of the information age, due to the increase in people communicate with the outside world information needs, dissemination of information display device having a function has become indispensable to modern electronic products. 显示装置由起始的阴极射线管(cathode ray tube, CRT)显示器发展至现今更轻薄的液晶显示器(liquid crystal display, IXD),已经广泛应用于通讯、信息及消费电子产品等。 The display device now slimmer liquid crystal display (liquid crystal display, IXD) from the starting of a cathode ray tube (cathode ray tube, CRT) monitor development, has been widely applied to communication, information and consumer electronic products. 然而,由于液晶显示器需持续提供电源供操作,所以更省电的电泳显示器(Electrophoretic display)的显示技术被开发出来。 However, since the liquid crystal display continuously provides power required for the operation, so more power an electrophoretic display (Electrophoretic display) display technology has been developed.

[0003] 利用计算机来处理与保存大量资料,然而,与纸张相比,由于计算机的体积、重量以及操作等均不及将信息记载于纸张印刷品的方便携带与便利阅读,因此在这种情况下, 基于电泳技术的电子纸显示器(Ε-paper display, EPD)应运而生,电子纸显示器的厚度可以与普通纸张相当,能够复制纸张的显示特点且能够重复利用,而且电子纸显示器能够显示动态画面。 [0003] The use of computers to store large data processing, however, compared with the paper, due to the volume of a computer, etc. and an operating weight of less information described in the print sheet easily and conveniently carried read, so in this case, electrophoresis technique based electronic paper display (Ε-paper display, EPD) came into being, the thickness of the electronic paper display may be rather plain paper, the paper can be copied and display characteristics can be reused, and the electronic paper display capable of displaying a moving picture. 电子纸以其较低的能源消耗和类似纸张的柔和显示效果以及可以替代纸张的前景预期,越来越受到市场的欢迎。 Electronic paper its low energy consumption and soft paper-like display could replace paper and the prospect of expectations, more and more welcomed by the market. 其优秀的保持特性非常适于文本阅读一类的静态显示 Its excellent retention characteristics well suited for reading the text of a class of static display

[0004] 目前研究较多的是基于电泳技术的电子纸显示器,电泳是指带电粒子在施加的电场中运动,其基本原理是:电泳液里面存在带电颗粒,这些带电颗粒在电场的作用下可以移动,且可以对环境光进行反射,如纸张般显示图像被人眼接收;在画面转换阶段,根据电泳液两端所加电压的大小和时间可以控制带电微粒在电泳液里面所在的位置,从而控制反射光的强弱实现灰阶显示;在画面保持阶段,使电泳液两端等电位,使得带电微粒在电泳液里面保持位置从而能够以低能耗保持静态画面,实现静态画面显示。 [0004] The current research is based on the electronic paper display electrophoresis, electrophoretic movement of charged particles refers to the applied electric field, the basic principle is: the presence of charged particles inside the electrophoresis liquid, these particles can be charged under the influence of an electric field mobile, and may be ambient light reflection, such as paper-like display image recipient eye; the screen transition phase, the voltage applied to both ends according to the size and electrophoretic fluid may control the time position of the charged particles in the electrophoretic fluid is located inside, whereby controlling intensity of the reflected light to achieve grayscale display; screen holding phase, the potential of both ends of the electrophoresis running buffer and the like, so that the charged particles in the electrophoretic fluid inside the holding position can be maintained with low energy consumption still picture, still picture display realized.

[0005] 然而现有技术中对EPD显示屏上画面的更新采用全局(全屏)刷新,如果屏幕的大小为600 X 800,每次传送的数据必须是600 X 800个像素数据,发送显示命令后,EPD控制器将显示600X800个像素值;即更新显示屏屏幕上的画面时,在显示屏上只有部分画面发生变化时,仍然将整个画面重新进行更新,由于现有技术中EPD的刷新速度慢(刷新速度约为700ms),采用全局刷新时会出现闪屏的现象。 [0005] However, the prior art to update the display screen using the Global EPD (full screen) to refresh, if the screen size is 600 X 800, each data transfer must be 600 X 800 pixel data, transmitted display command , EPD controller will display 600X800 pixel values; i.e. update screen on the display screen, only a part of the screen when the change will still re-update the whole picture on the display screen, since the prior art EPD refresh slower (refresh rate of about 700ms), using the phenomenon of splash screen will appear when the global refresh.

[0006] 现有技术中有许多关于电子纸显示器及其驱动方法的专利,例如申请号为200880000725. 3的中国专利申请,然而均没有解决以上所述的现有技术的缺点。 [0006] There are many prior art patents on electronic paper display and a driving method, for example, Application No. 200880000725.3 Chinese patent application, however, did not address the drawbacks of the prior art described above.
