One of the major goals of the development of e-paper is to replace the traditional computer monitors.
Traditional computer monitors have a lot of problems while e-paper does not have.
Firstly, e-paper does not need backlight. In order to display images on the screen, traditional computer monitors have to emit strong enough light, which is called backlight. The lighting of the screen consumes a lot of power. Other problems such as to control the strength of the light, to illuminate the screen evenly, etc. will also have to be solved.
Secondly, e-paper do not need refresh constantly, while the monitors have to be refreshed constantly, which means to display images for more than 60 times a second. This is so important that refresh rate became an important parameter for a computer monitor.
Thirdly, e-paper has no glare problem. Glare is a problem for traditional computer displays. Glare is caused by reflecting of light from the computer screen. As we discussed before, the computer monitor have to emit its own light to show the image; therefore, the light reflecting from the screen will distract the user.
