During to bending, the display width of adjusting displayed content；When the only vertical bending of display screen 100, the display of adjusting displayed content is high
Degree；When display screen 100 not only transverse curvature but also during vertical bending, the now display width and display width of adjusting displayed content.
Also referring to Fig. 9, before the transverse curvature of display screen 100, display screen 100 shows for plane, from display screen 100 just
Top is observed, and can obtain the display effect of approaches uniformity.Figure 10 is referred to, after 100 transverse curvature of display screen, display screen 100
Shown with plane display mode identical mode, but because multiple flexural deformation, people occurs in a lateral direction in display screen 100
Eye 400 obtain visual effects be：Display screen 100 is bigger with the angle of the direction of observation 500 of human eye 400, the size of display content
It is bigger；Display screen 100 is smaller with the angle of the direction of observation 500 of human eye 400, and the size of display content is smaller.Namely such as Figure 10
Shown in, the visual size of the display content around doublet in display screen 100 is larger, and the display content around single dotted line is regarded
Feel that size is smaller.
When the initial display width of display content is w, the vision width that human eye 400 is obtained is w*cos θ, therefore vision
Width can be less than display width.In order to increase display effect, the display width of display screen 100 can be adjusted, adjust display width
Formula be：W=w/cos θ, wherein, W is the display width after regulation, and w is initial display width, and θ is the first angle.When aobvious
When showing width adjusting for W, vision width is changed into W*cos θ=w/cos θ * cos θ=w, vision width and initial display width w phases
Together, the display effect of display screen 100 is good, and the visual effect of the display width of the display content of display screen 100 after overregulating is illustrated
Figure is as shown in figure 11.
Also referring to Figure 12, vertically before bending, display screen 100 shows display screen 100 for plane, and human eye 400 is from display
Observation, can obtain the display effect of approaches uniformity directly over screen 100.Figure 13 is referred to, after display screen 100 vertically bends, is shown
Display screen 100 shows with plane display mode identical mode, but occurs bending change in a vertical direction due to display screen 100
Shape, human eye 400 obtain visual effect be：Display screen 100 is bigger with the angle of the view direction 500 of human eye 400, display content
Size is bigger；Display screen 100 is smaller with the angle of the direction of observation 500 of human eye 400, and the size of display content is smaller.As in Figure 13
Shown, numeral 1,2,3 is larger on display screen 100, dials key and " x " key etc. smaller.
When the initial display of display content is highly h, the eye level that human eye 400 is obtained is h*cos θ, therefore vision
Height can be less than display height.In order to increase display effect, the display of display screen 100 can be adjusted highly, regulation display height
Formula be：H=h/cos θ, wherein, H be display after regulation highly, h is initial display height, and θ is the first angle.When aobvious
When showing that height is adjusted to H, eye level is changed into H*cos θ=h/cos θ * cos θ=h, eye level and initial display height h phases
Together, display effect is good.Visual effect schematic diagram such as Figure 14 institute of the display height of the display content of display screen 100 after overregulating
Show.
When bending when display screen 100 not only transverse curvature but also vertically, the regulation of display width can be first carried out, then shown
The regulation of height, or first carry out showing the regulation of height, then the regulation of display width is carried out, so as to realize the tune of display size
Section.Wherein, display width is identical with the adjusting method of display height with foregoing display width with the adjusting method of display height,
It is not repeated herein.
Figure 15 is referred to, in present embodiment, above-mentioned display method is according to the first angle theta, regulation target observations point institute
Also include after the step of display size of the display content of predeterminable area 800 on display screen 100：
Step S160：Obtain the visual pattern after display screen 100 is adjusted.
After the display size of the display content of predeterminable area 800 on display screen 100 where regulation target observations point, due to
The display size of the display content of predeterminable area 800 is exaggerated, therefore portions of display content in predeterminable area 800 can be moved
The region beyond predeterminable area 800 where moving target observations point.The display size of this portions of display content by thus according to
What the first angle theta formed between the plane 600 of predeterminable area 800 and second where target observations point was adjusted, target is seen
The angle and the first angle theta formed between other regions beyond the predeterminable area 800 at a place and the second plane 600 is examined very may be used
Can be different, so that visual size can change, display effect becomes uneven.Therefore, to the display content of display screen 100
After display size is adjusted, the visual pattern after display screen 100 is adjusted need to be obtained, so as to further be adjusted.
Step S170：According to the visual pattern after regulation, the predeterminable area on display screen 100 where target observations point is determined
The visual size of 800 display contents.
According to the visual pattern for obtaining, the preset areas on display screen 100 where the target observations point of display screen 100 can be obtained
The visual size of the display content of domain 800.
Step S180：Judge whether visual size is identical with default visual size, if differing, according to the first angle
θ, the display size of the display content of predeterminable area 800 on display screen 100 where regulation target observations point.
After the visual size of the display content of predeterminable area 800 in acquisition display screen 100 where target observations point, pass through
Compared with default visual size, visual size and the default vision of the predeterminable area 800 where judging target observations point
Whether size is identical.If differing, show that the display effect of display screen 100 is uneven, now, according to where target observations point
The the first angle theta regulation display size formed between the plane 600 of predeterminable area 800 and second.It is adjusted to display size
Afterwards, visual size is repeatedly obtained, and display size is adjusted according to the new visual size for obtaining, entered by display size
Row repeatedly regulation, finally makes display screen 100 have uniform display effect.
After the display size to the display content of display screen 100 is adjusted, due to part display size being carried out
Amplify, because the tool of display screen 100 has the dimensions, therefore whole contents can not be shown.If stilled need in display all
Hold, then need to carry out a certain proportion of compression to overall display size.After being compressed to overall display size, then to display
Size is repeatedly adjusted, so that display screen 100 can either show the content that need to all show, display screen 100 can again had
There is uniform display effect.
Additionally, when some predeterminable areas 800 are smaller with the angle of the direction of observation 500 of human eye 400, visual size ratio now
It is smaller, especially for some predeterminable areas 800 and the direction of observation 500 of human eye 400 close to it is parallel when, almost not seeing now should
The content shown on predeterminable area 800.Therefore, before display size is adjusted, the vision figure of display screen 100 can be obtained ahead of time
Picture, the visual size of each display content of predeterminable area 800 in display screen is obtained according to visual pattern, when a certain predeterminable area
It is to show the predeterminable area 800 and eye-observation direction 500 close to parallel when 800 visual size is less than default size,
In order to adjust display size faster, can directly ignore the content that the predeterminable area 800 should show, be indirectly displayed as white screen,
