Why Is E
Currently on the market a Electronic Reader wave
, various vendors rush to launch electronic reader Attacking boom, the market area we do not talk aside (easy to be seen as the gun culture), just why the e-paper e-reader chat about industry plays a key role . However, these data are purely of subjective feeling, not objective and are probably not comprehensive enough.
Must first understand the concept of electronic paper, electronic paper displays in general are different reasons for the invention is to be a substitute for paper-based, basic reading compared with the general characteristics of displays, electronic paper will not self-luminous, completely dependent on the human eye can see the reflection of light from outside the content of this advantage is to reduce the pressure to read, Here is a simple example, in well lit conditions, the same half an hour staring at a screen with a white row, eye fatigue degree or different. Therefore, the development of electronic paper
the beginning of the concept paper is to develop the closest. However, the reading level, high-end coated paper up to Eighty percent of the refractive capacity, that is only able to read little light, but the refractive index of electronic paper in general fell about four percent, so the previous e-reader, rarely adding touch features, but also because the resistance is lower cost will result in touch about 15% of light loss, the electronic equivalent to a continuous decrease of reflection paper twice.
Another threshold is the reaction rate, the electronic imaging process requires the paper to renovate the entire page, that is, flip the page will need to brush the black screen after all the procedures, or whitewashed, touch a key objective is as handwriting used record, but the touch detection response was much faster than the refresh rate of most electronic paper under the premise of the current hand-written record of the e-book can be even less.
Although the electronic paper that so many shortcomings, the market of electronic readers are invariably chosen as the electronic paper display, reading less pressure, the electronic paper modules more light than existing liquid crystal displays, and does not require backlighting, it only needs power when the flip procedures to be used in flea market Advertisement Electronic paper, for example, can drive only 2 AA batteries, and no need to replace the content in, at least show a few weeks duration; alone device endurance capacity, beyond the LCD display. In addition, flexible electronic paper technology has been the purpose of, imagine, if folding e-book reader, or rolled, but also conducive to carrying and collection.
Is why most electronic reader instead of liquid crystal display using electronic paper, the basic conditions of difference is already clear, the focus of e-reader is not high dynamic display capabilities, but allows users to read a long time, and the device itself as not to heat (liquid crystal lamp so hot ~), and can be read at any time (e-paper flip can be maintained after the imaging), although a number of ways of reading digital content, but to be able to read books with general experience, the short term is still the advantage of electronic paper.
