Embodiment

Now with reference to accompanying drawing the utility model is described more fully, exemplary embodiment of the present utility model shown in the drawings.

Fig. 1 is the perspective schematic view according to theflexible display panels 100 of the utility model embodiment, and Fig. 2 is the cut-open view along theflexible display panels 100 shown in Fig. 1 of the intercepting of the line II-II among Fig. 1.

See figures.1.and.2,flexible display panels 100 be included in the upper directed viewing area D in the first plane (x-y plane) and on the plane of viewing area D outside directed non-display area N1, N2, N3 and N4(N1 and N3 directed on the x-z plane different from the first plane (x-y plane), N2 and N4 are directed on the x-y plane).Among non-display area N1, N2, N3 and the N4 to stride across non-display area N1 and N3 edge-z direction that viewing area D faces with each other folding ,-z direction and the z opposite direction that shows viewing area D institute edge.

Since non-display area N1 and N3 along with the z opposite direction that shows viewing area D institute edge-the z direction is folding, so when seeingflexible display panels 100, the user identifies width W from the front (z direction) of viewing area D as the user₁, wherein, non-display area N1 and N3 are in width W₁The place is folded into around the right side of viewing area D and the border in left side.

With reference to Fig. 2, because the width W of non-display area N1 and N3 burst₁Become than non-display area N1 and the folding original width W before of N3₀Little a lot, so recognizing the size on the border that is formed by non-display area N1 and N3 of viewing area D, the user significantly reduces.When the area of viewing area D before non-display area N1 and N3 are folding and when not changing respectively afterwards, the Area Ratio of the non-display area N1 that the user identifies and N3 and viewing area D reduces, and therefore, the D relatively effect of amplification in viewing area can be shown.Because the width (W that reduces by non-display area N1 and N3₀-W₁) can increase the width of viewing area D, so when the identical display device of the specification thatflexible display panels 100 is applied to specification andflexible display panels 100, compare with other display panels,flexible display panels 100 can realize the picture screen that increases.

By the intrinsic curvature radius R of the folded part of viewing area D and non-display area N1 and N3 and the thickness T sum offlexible display panels 100, can determine the folding width W of non-display area N1 and N3₁Although the below is described, but because the intrinsic curvature radius R of the folded part of viewing area D and non-display area N1 and N3 and the thickness T offlexible display panels 100 can significantly reduce, so the user can recognize almost non-boundary of the viewing area D that formed by non-display area N1 and N3.

Because it is flexible consisting of theflexible substrates 111 offlexible display panels 100, so be difficult onflexible substrates 111, directly form viewing area D and non-display area N1 and N3.Therefore, although not shown, the method for makingflexible display panels 100 may further comprise the steps: formflexible substrates 111 at the substrate of glass (not shown) with rigidity;Form restraining barrier 112 inflexible substrates 111; 112 form viewing area D and non-display area N1 and N3 on the restraining barrier; Form flexibility andseal member 113 to cover viewing area D; Use the second bonding agent (not shown) that thesecond diaphragm 115 is attached to flexibility andseal member 113; The substrate of glass (not shown) is separated withflexible substrates 111; And use the first bonding agent (not shown) that thefirst diaphragm 114 is attached toflexible substrates 111.

Thefirst diaphragm 114 and thesecond diaphragm 115 according to present embodiment can be applied to following other embodiment that will describe of the present utility model.

Non-display area N1 on the left side of the viewing area D of the flexible display panels 100-B of Fig. 5 and the non-display area N3 on the right side along and show viewing area D direction (z direction, see Fig. 1) when opposite-z direction is folding, theflexible display panels 100 shown in pie graph 1 and Fig. 2.

Inflexible display panels 100, when non-display area N1 and N3 are folded, boundary formation curved surface that can be between viewing area D and non-display area N1 and N3.

Refer again to Fig. 2, comprise that the borderline region RB of predetermined curved surface is positioned at D(first area, viewing area RI) and non-display area N3(second area RII) between.Borderline region RB forms the curved surface with intrinsic curvature radius R.

In current embodiment, the non-display area N3 of second area II extends from borderline region RB.When the user from the front (z direction) of viewing area D when seeing foldedflexible display panels 100, the width W of the non-display area N3 that the user identifies from the front of viewing area D₁Be considered to the intrinsic curvature radius R of the folding part of viewing area D and non-display area N3 and the thickness T sum of flexible display panels 100.In current embodiment, the width W of the non-display area N3 that is identified by the user₁RB is identical with borderline region.

The thickness T offlexible display panels 100 can be selected in the scope of tens microns (μ m) and hundreds of micron (μ m).Specifically, because in the situation of small-sized display device, the thickness of flexible display panels can be from than selecting in the less scope of above-mentioned scope, so the width W of the non-display area that the user identifies₁Can reduce further.Be apparent that the utility model is not limited to above-mentioned thickness range, if necessary, then can select the thickness range wider than above-mentioned thickness range.

Fig. 9 shows the width W that the user of the intrinsic curvature radius R of the folding part of viewing area D and non-display area N3 and non-display area N3 identifies₂And W₃Between relation.

With reference to Fig. 9, when the thickness T of hypothesisflexible display panels 100 be uniformly and non-display area N3 folded so that borderline region RB has radius of curvature R₂, the width W of the non-display area N3 that the user identifies₂It is radius of curvature R₂Thickness T sum (W withflexible display panels 100₂=R₂+ T).When non-display area N3 folded so that the radius of curvature R of borderline region RB₃Compare radius of curvature R₂When larger, the width W of the non-display area N3 that the user identifies₃It is radius of curvature R₃Thickness T sum with flexible display panels.In other words, along with the increase (R of radius-of-curvature₃＞R₂), the width W of the viewing area N3 that the user identifies₃Increase.

The intrinsic curvature radius of the part that viewing area D and non-display area N3 are folding can be between 0.01mm and 10mm.When the intrinsic curvature radius of this part during less than 0.01mm,flexible display panels 100 can not keep folded state because of bending stress, when the intrinsic curvature radius of this part during greater than 10mm, and the width W of non-display area N3₃Increase.Specifically, in the situation of small-sized display device, the scope of radius-of-curvature can be chosen as less than 1mm, so that the width W of the non-display area N3 that the user sees₃Can further reduce.

With reference to Figure 10, the viewing area D of first area RI extends from borderline region RB.When the user sees foldingflexible display panels 100 from the front of viewing area D, the width W of the non-display area N3 that the user identifies₄Be 0.Like this, in current embodiment, the user can recognize almost non-boundary of non-display area N3.

With reference to Figure 11, the two can be arranged on the viewing area D of first area RI and the non-display area N3 of second area RII among the borderline region RB.About this point, the width W of the non-display area N3 that the user identifies₅The width W of the non-display area N3 that identifies greater than the user₄And the width W of the non-display area N3 that identifies less than the user (as shown in figure 10),₁(as shown in Figure 2).Yet, even in this case, the width W of the non-display area N3 that the user identifies₅Also less than the width of the non-display area of thepanel display board 10 among Fig. 3 and Fig. 4, in Fig. 3 and Fig. 4, non-display area N1 and N3 are folding.

In the situation of theflexible display panels 100 of Fig. 1, non-display area N1 and N3 on the left and right sides of viewing area D are folded.Yet the utility model is not limited to this.In other words, spirit of the present utility model is applied to the folded situation of any one non-display area among non-display area N1 and the N3 equally.

Figure 12 is the perspective schematic view according to theflexible display panels 200 of another embodiment of the utility model, Figure 13 is the cut-open view along theflexible display panels 200 shown in Figure 12 of the intercepting of the line XIII-XIII among Figure 12, and Figure 14 is the non-display area N2 of Figure 12 and the schematic plan view that N4 folds the example of flexible display panels 200-B before.

Hereinafter, will current embodiment be described for the difference of the embodiment of Fig. 1 and Figure 12.

With reference to Figure 14, in the flexible display panels 200-B according to current embodiment, be positioned at viewing area D downside non-display area N2 and be positioned at viewing area D upside non-display area N4 along with show viewing area D direction (z direction) opposite-the z direction is folding.As a result, according to theflexible display panels 200 of another embodiment of the utility model as shown in Figure 12.

With reference to Figure 12 and Figure 13, non-display area N1, N2, N3 and N4 thatflexible display panels 200 comprises viewing area D and is positioned at viewing area D outside.Among non-display area N1, N2, N3 and the N4 stride across non-display area N2 that viewing area D faces with each other and N4 along with the z opposite direction that shows viewing area D institute edge-the z direction is folding.

Since non-display area N2 and N4 along with the z opposite direction that shows viewing area D institute edge-the z direction is folding, when seeingflexible display panels 200, the user identifies width W so the user is from the front (z direction) of viewing area D₆, wherein, non-display area N2 and N4 are in width W₆The place is folded into around the border of upside and the downside of viewing area D.

As mentioned above, because the width W of non-display area N2 and N4 burst₆Become than the original width W before non-display area N2 and N4 are folding₀Little a lot, so recognizing the border of the viewing area D that is formed by non-display area N2 and N4, the user significantly reduces.Specifically, because the area of the non-display area N2 at pad cell P place is larger, thus the non-display area N2 at pad cell P place is folding, so that recognizing the border of the viewing area D that is formed by non-display area N2, the user significantly reduces.
