Embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention is described in detail.
Fig. 1 shows the schematic diagram of the transparent display according to the embodiment of the present invention.As shown in Figure 1, the both sides up and down according to display panel 11 back side of the transparent display of the embodiment of the present invention are provided with light source 12, are preferably LED light source.Light source 12 irradiates backward, and the light reflected frontward utilizing reflection shield 13 to be irradiated backward by light source 12 is on display panel 11.
Should be appreciated that light source 12 and reflection shield 13 are not limited only to be arranged on the both sides up and down of display panel 11, also can be arranged on the left and right sides of display panel 11.When size of display panels is less, also only light source and reflection shield can be set in the side of display panel; When size of display panels is larger, in order to make light more even, also light source and reflection shield can be all set on three sides of display panel, even four sides
Because light source 12 and reflection shield 13 are all positioned at the proceeds posterolateral of display panel 11, so can not impact the Transparence Display effect of transparent display panel 11, and light source 12 improves the brightness of transparent display panel, improves the display effect of display panel.But the light major part reflected by reflection shield 13 is high angle scattered light, thus the positive apparent brightness of display panel cannot be improved.
For head it off, preferably, also there is according to the display panel back side of the embodiment of the present invention microstructure of multiple protuberance formation, make towards the direction of the light of the back surface incident of display panel to change, make it to change the direction outgoing to being approximately perpendicular to display panel into, namely, what emergent ray is concentrated on user faces approximate angle, thus improves the display effect of display panel further.Fig. 2 shows the light path simulation drawing of the transparent display panel according to the embodiment of the present invention, as shown in Figure 2, when the display panel back side also has the microstructure of multiple protuberance formation, can make to change direction outgoing to being approximately perpendicular to this display panel into towards the light of the back surface incident of display panel, even if most of light concentrates on the direction of user's viewing, thus promote the brightness of display panel, improve image quality.
Protuberance shown in Fig. 2 is triangle, but those skilled in the art are to be understood that the shapes such as such as trapezoidal, half elliptic are also feasible, may be used to according in display panel of the present invention as long as can play any microstructure changed into the direction outgoing being approximately perpendicular to this display panel by the light of the back surface incident towards display panel.
Fig. 3 shows the index path of triangular shaped projections to the incident light of different angles.As seen from Figure 3, after light enters triangular shaped projections, reflect at the inclined-plane place of projection, thus change exit direction, and towards being approximately perpendicular to the direction outgoing of display panel.Fig. 4 and Fig. 5 shows the light path schematic diagram of trapezoidal protuberance and half elliptic protuberance, the direction of incident light can be changed into towards the direction outgoing being approximately perpendicular to display panel.The invention is not restricted to above-mentioned shape, anyly the light of the back surface incident towards display panel all to be fallen within the scope of the present invention by the lobe shape changed into the direction outgoing being approximately perpendicular to this display panel.
Should be appreciated that the shape of protuberance needs not to be on all four, can change according to the angle of incident light, and make the lobe shape of diverse location different, with better by light with the direction outgoing perpendicular to display panel.
Fig. 6 and Fig. 7, to be easy to most the triangular shaped projections manufactured, shows the schematic diagram of the transparent display panel according to the embodiment of the present invention.Accompanying drawing just in order to explain and the present invention be described, and and be not intended to carry out any restriction to the present invention.
The schematic diagram of protuberance when the right side that Fig. 6 shows only display panel exists light source.As shown in Figure 6, the back side is pasted with one deck blooming 22 to transparent display panel 21, and blooming 22 has multiple triangular shaped projections 23.Triangular shaped projections 23 is acute angle from the angle of blooming 22 outwardly convex, and the right side of the acute angle the top of the horn of the projection of triangular shaped projections 23 deflection triangular shaped projections 23, namely near the side of light source.Reflecting through triangular shaped projections 23 from the light of light source outgoing, changing the direction outgoing to being approximately perpendicular to display panel 21 into.
The schematic diagram of protuberance when the left and right sides that Fig. 7 shows display panel all exists light source.In this case, near the tapered point deflection left side of triangular shaped projections 23 projection of left side light source, the left side light source that it is close is namely partial to; Near the tapered point deflection right side of triangular shaped projections 23 projection of right side light source, be namely partial to the right side light source that it is close.Thus, reflecting through triangular shaped projections 23 from the light of light source outgoing, changing the direction outgoing to being approximately perpendicular to display panel 21 into.
Further, Fig. 6 and Fig. 7 intermediate cam shape protuberance 23 is isosceles right triangle, and the tapered point being positioned at the isosceles right triangle projection on the left of display panel is positioned at left side, and the tapered point being positioned at the isosceles right triangle projection on the right side of display panel is positioned at right side.The bump sizes of triangular shaped projections 23 is 5 to 50 microns.Can find out by adopting the simulation of Lighttools optical software, by adopting the display panel according to the embodiment of the present invention, comparatively uniform lighting effect can be obtained, thus provide area source comparatively uniformly for Transparence Display, achieve good Transparence Display effect.
Fig. 8 shows the manufacture method of the transparent display panel according to the embodiment of the present invention.Step S1, the back side of transparent display panel 21 applies blooming 22; Step S2, blooming 22 applies optical cement; Step S3, forms multiple protuberance 23 by patterning processes; Step S4, is cured process to multiple protuberance 23.
Preferably, this patterning processes is pressing process, is suppressing multiple protuberance 23 by the mode of the roll-in adopting pressure roller on optical cement.The technique of this roll-in is comparatively simple, is easy to realize and cost is low, easily can extrude triangle, the figure such as trapezoidal at optical cement top roll.
By adopting transparent display panel disclosed in this invention and manufacture method, display device, improving the problem that Transparence Display brightness is too low, light is uneven, strengthening the display effect of Transparence Display.
Although describe embodiments of the present invention by reference to the accompanying drawings, but those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, such amendment and modification all fall into by within claims limited range.
