In actual implementation procedure, for different files, its indicating characteristic data can be different, the mode of its display image also can be slightly different, but control principle is identical, all the voltage of two electrodes by controlling the actuator below flexible screen, change area and the shape of actuator, thus realize raised or sunken on hardware of flexible screen, apparently, the position of the alteration of form of actuator is corresponding with the position at display image place, and for how controlling to show the raised or sunken of image, raised or sunken position can be set as required, or the character according to display image self sets.
The present embodiment can make image present the display effect of 3D, compares existing single document display mode, and the present embodiment has enriched the display mode of file, also enhances the expressive force of file content.
Embodiment 2
The present embodiment provides a kind of document display method of mobile terminal, and as shown in Figure 3, the difference of the document display method of the present embodiment and embodiment 1 is: described file to be output is audio file, and described display image is audio frequency polar plot; Step 101 comprises:
Step 101a, by the decoding of described audio file to obtain Wave data, fft algorithm conversion is carried out to described Wave data, from scaling results, extracts the voice data in each moment;
Wherein, this audio file is the audio file of nondestructive compression type, described voice data comprises the amplitude of some frequency ranges and each frequency range, the present embodiment have employed audible spectrum analytical technology, utilize Fast Fourier Transform (FFT) that continuous print Wave data in time domain is converted to voice data discrete in frequency domain, also namely extract the voice data in the per unit moment of Wave data, voice data is shown.Suppose that the voice data extracted comprises the amplitude of 5 frequency ranges and each frequency range.
Step 101b, generate audio frequency polar plot according to described voice data;
Wherein, described audio frequency polar plot comprises some graphic elements, each graphic element is correspondingly for representing a frequency range in described voice data and amplitude thereof, each graphic element is a rectangular show bar, the length of described show bar for represent corresponding frequency range and width for representing corresponding amplitude, in a straight line, the frequency size according to the frequency range of correspondence is arranged side by side successively on the base of whole show bar.
And convex manner is described flexible screen is provided with a rectangular display box 300 for showing audio frequency polar plot, audio frequency polar plot is shown in wherein, as shown in Figure 4,5 show bars 301 are had in display box 300, the length of each show bar 301 represents five frequency ranges in voice data respectively, the frequency range of the frequency range of the length h1 20Hz of expression successively (hertz) to 500Hz from left to right of each show bar 301, the frequency range of 500Hz to 1000Hz, the frequency range of 1000Hz to 5000Hz, the frequency range of 5000Hz to 10000Hz and 10000Hz to 20000Hz.The width w1 of each show bar 301 represents the amplitude in this frequency range, and the audio file of voltage when can be exported by audio playing device by to(for) the acquisition of amplitude or current detecting are obtained.
The frequency size of the frequency range of base according to correspondence on the base straight line 302 of described display box of whole show bar 301 is arranged side by side successively.When utilizing flexible screen to show, the viewing area only residing for five show bars is raised or sunken to present described audio frequency polar plot.When the viewing area of described show bar is protruding, described bossing is rectangular shape, and the height of the projection of the rectangular shape that each show bar is corresponding is all identical.That is, each show bar its height when projection is consistent, and the height of projection of each show bar inside is identical, is in same level after making each show bar projection.Namely the width maximal value of described show bar equals the width w of described display box 300, and minimum value is zero, and also the amplitude maximum of show bar can be the width w of display box 300, minimum value then with base straight line 302 conllinear.
The present embodiment also provides a kind of mobile terminal 100b, and as shown in Figure 5, the difference of the mobile terminal of the present embodiment and the mobile terminal of embodiment 1 is: described file to be output is audio file, and described display image is audio frequency polar plot; Described generation unit 2 comprises:
Extraction unit 20, for decoding described audio file to obtain Wave data, and extract the voice data in each moment from described Wave data, described voice data comprises the amplitude of some frequency ranges and each frequency range;
