For making the purpose, technical solutions and advantages of the present invention clearer, embodiments of the present invention are described in further detail below in conjunction with accompanying drawing.
The present inventor finds that for different environment and different reading materials, the user may be different to the requirement of screen size.For example, in comparatively crowded subway, screen may can only draw back 2/3; And for example, when seeing the e-book of text, do not use whole screens that effect preferably may also be arranged.Therefore wish to pass through the solution of the present invention, the user can arbitrarily adjust screen size according to oneself hobby and demand, and simultaneously, displaying contents also can be adjusted automatically according to screen size, regardless of screen size, can show complete content all the time.
First embodiment of the invention relates to a kind of display packing of electronic information reader, and this reader of the display packing of this electronic information reader comprises Scroll container and flexible screen, and this flexible screen can curl and be accommodated in this Scroll container.
The flow process of first embodiment as shown in Figure 2.
In step 101, the variation of the effective display width by the sensor monitors flexible screen.The height of flexible screen is fixed, and width is that the user can adjust voluntarily.Effectively display width is exactly that flexible screen is unfolded from the Scroll container, the effective screen width of displaying contents.
After this enter step 102, judge whether effective display width variation has taken place,, continue monitoring otherwise get back to step 101 if enter step 103.
In step 103,, just displaying contents is set type again according to current effective display width as long as variation has taken place effective display width.
After this enter step 104, refresh flexible screen.
In above-mentioned steps 103, again the method for Pai Baning have multiple, below for two examples.
Method one: other sets type classification again.
Set in advance the rank of a plurality of display widths.The display width of actual use is little and immediate rank than current effective display width when setting type again.
Carry out actual composing by predetermined width rank, can guarantee the display effect of the space of a whole page, simplify the workload of setting type.Because the space of a whole page of some information (as webpage) is based on specific resolution design, so only have preferable display effect under several specific resolution.If show that with irregular resolution not only display effect is not good enough, the calculated amount during composing also can be bigger.
For example, the rank of width can be 480,600,800,1024,1280 etc., if current effective display width is 613, the then actual display width that uses is 600, stays the blank of 13 pixels on the limit.
Method two: use whole effective display widths during composing.
For example, current effective display width is 613, and the then actual display width that uses also is 613.
Show with whole effective display widths, can give the display area of user, be particularly suitable for the demonstration of literal electron-like book with maximum.
With the variation of effective display width of sensor monitors flexible screen, set type again according to current effective display width in the back that changes, can make the live part optimum matching of display mode and flexible screen, the invisible situation of partial content can not appear.The user can as long as draw back required width, will show the optimal space of a whole page on the screen according to the optimal screen width of dissimilar selections of information, and is convenient for users to use.

After this enter step 302, judge whether effective display width variation has taken place,, continue monitoring otherwise get back to step 301 if then enter step 303.
In step 303, judge that further the time that effective display width stops to change surpasses scheduled duration, if then enter step 304, continue monitoring otherwise get back to step 301.
Stop to change for effective display width of flexible screen multiple judgment mode can be arranged, can be that any variation does not take place effective display width, but consider the shake of staff or the factor of ambient vibration, also can allow effective display width to have only the fluctuation of very small (as 1,2 pixel).
Scheduled duration is better in second at 0.2-1 usually, if oversize, can give the user with sluggish bad experience; If too short, then can before putting in place, repeatedly not refresh the twitch flexible screen, do not have energy-conservation effect.
In step 304, displaying contents is set type again according to current effective display width.
After this enter step 305, refresh flexible screen.After this getting back to step 301 continues to monitor.
After effective display width of flexible screen stops to change, set type again again and refresh, can significantly reduce the number of times of setting type and refreshing, thereby reduce the consumption of valuable electric energy effectively.
Four embodiment of the invention relates to a kind of display packing of electronic information reader.
The 4th embodiment improves on the basis of second embodiment, main improvements are, change enough greatly and set type again again after stopping variation and refresh at the effective display width of flexible screen, can further reduce the number of times of setting type and refreshing like this, thereby further reduce the consumption of valuable electric energy.
The idiographic flow of the 4th embodiment as shown in Figure 5.Wherein step 401-403 respectively with 201-203 roughly the same, step 405-407 respectively with 205-207 roughly the same.The key distinction is that 404 is different with 204 Rule of judgment.
