Embodiment
Because the ability of flexible material opposing high temperature or high humidity is not as glass, therefore if use the substrate material of flexible material, may make made electrophoresis type display as array base palte, under the environment of high temperature or high humidity, produce the problem of fiduciary level deficiency.In addition, because flexible material has the characteristic of flexible, therefore after repeatedly bending, around the driving circuit or the transparency electrode place of viewing area also may have the phenomenon generation of broken string.Therefore, the following embodiment of the present invention will propose a kind of electrophoresis type display, and it utilizes shell to coat display module, even if therefore display module is to use flexible array base palte, also can provide enough intensity and fiduciary levels by shell.
Fig. 1 illustrates the exploded view according to the electrophoresis type display of one embodiment of the invention, and Fig. 2 then illustrates the stereographic map of the electrophoresis type display of Fig. 1.As shown in the figure, the electrophoresis type display of present embodiment comprises display module 100, drain pan 210 and top frame 220.Wherein, drain pan 210 will be combined into a shell 200 by tying part (fastener) 300 with top frame 220, and this shell 200 will coat display module 100, providing display module 100 enough support structure, and avoid display module 100 to be subjected to the invasion and attack of aqueous vapor and high temperature.
Fig. 3 illustrates the longitudinal diagram that cuts along the line segment A of Fig. 2.As shown in the figure, the display module 100 of present embodiment comprises flexible array base palte 110, front panel (Front plane laminate; FPL) 120, driving circuit 130 and flexible printed circuit board (Flexible printed circuit board) 140.Wherein, flexible array base palte 110 comprises viewing area 112, and the periphery circuit region 114 that is disposed at 112 peripheries, viewing area.Front panel 120 is positioned on the viewing area 112.Driving circuit 130 electrically connects flexible array base palte 110.Flexible printed circuit board 140 electrically connects driving circuit 130.
In the present embodiment, the periphery circuit region 114 of above-mentioned top frame 220 flexible array base palte 110 for frame covers, drain pan 210 then coat the one side of flexible array base palte 110 back to front panel 120.In other words, though shell 200 coats display modules 100, expose front panel 120 to small part but still have a display aperture 230.So not only can keep the normal Presentation Function of electrophoresis type display, and solve the broken string problem that produces because of overflexing.
Though Fig. 1 is complete structure for drain pan 210 is illustrated, in fact, drain pan 210 also can have a plurality of holes 212 arrangements and (illustrate as Fig. 4) thereon.In case this is to consider that aqueous vapor intrudes into shell 200 inside, these holes 212 can assist aqueous vapor is discharged, and can not be accumulated in the shell 200.
In the present embodiment, the material of shell 200 (comprising drain pan 210 and top frame 220) can be various plastics, for example: polycarbonate (Polycarbonate; PC) or acrylonitrile-butadiene-phenylethylene polymkeric substance (Acrylonitrile-Butadene-Styrene; ABS).
As shown in Figure 1, the knot spare of present embodiment 300 can be the trip fastener.But this does not get rid of being suitable for of other kind knot part, and those skilled in the art should look elasticity of demand at that time selects.
Should be appreciated that above-mentioned " flexible array base palte " should be interpreted as: " substrate material is the array base palte of flexible material ".For instance, the substrate material of the flexible array base palte 110 of present embodiment can be polyimide (Polyimide; PI), polyethylene terephthalate (Polyethylene terephthalate; PET), polyethersulfone (Polyethersulfone; PES), Triafol T (Cellulosetriacetate; TAC) or photosensitive macromolecular (Photosensitive polymer).Certainly, more than the material lifted only be illustration, be not that the substrate material of flexible array base palte also can be other flexible material in order to restriction the present invention.
In addition, the driving circuit 130 of Fig. 3 is when coming to electrically connect with flexible array base palte 110 and flexible printed circuit board 140 by the circuit 116 on the flexible array base palte 110.In addition, though Fig. 1 is chip glass joint (Chip on glass for driving circuit 130 is illustrated; COG) structure, but other suitable encapsulating structure, for example the chip mantle engages (Chip on film; COF) and coil type chip join (Tapeautomated bonding; TAB), also can be one of embodiment of driving circuit.
In addition, in order to strengthen the protection to front panel 120 and driving circuit 130, the display module 100 of Fig. 3 also can comprise protective seam 150, edge protection material 160 and peripheral armature 170.Wherein, protective seam 150 covers the one side of front panel 120 back to flexible array base palte 110.Edge protection material 160 is around the edge of front panel 120.170 parcel driving circuits 130 of periphery armature.
Below will lift example of the present invention, the electrophoresis type display of key diagram 1～Fig. 4 can have enough fiduciary levels really under the environment of high temperature and high humidity whereby.In the following description, annexation of having carried in the above-described embodiments and material will no longer repeat to give unnecessary details, and only just need further not define the person and be replenished, close chat earlier bright.
In this example, electrophoresis type display has following common parameter:
(1) drain pan 210 is 0.2mm with the thickness of top frame 220;
(2) length of drain pan 210 and width are respectively 145.5 ± 0.15mm and 112 ± 0.15mm;
(3) length of top frame 220 and width are respectively 145.5 ± 0.15mm and 112 ± 0.15mm;
(4) if hole 212 is arranged, the diameter of hole 212 is 1.5mm, and spacing is 4.9mm;
(5) substrate material of flexible array base palte 110 is a polyimide; And
(6) thickness of flexible array base palte 110 is 0.01mm.
Under the condition of above common parameter, will be with regard to the material (polycarbonate and acrylonitrile-butadiene-phenylethylene polymkeric substance) of shell 200, and drain pan 210 whether complete (drain pan 210 of Fig. 1 and the drain pan 210 of Fig. 4), divide into 4 groups, and carry out motion test respectively, store test and thermal cycle test.
Below will chat respectively bright motion test, store the condition of test and thermal cycle test:
Motion test: persistent switch is 240 hours under the environment of 40 ℃ of temperature and relative humidity 90%.
Store test: storage is 240 hours under the environment of 60 ℃ of temperature and relative humidity 80%.
Thermal cycle test: environment temperature circulates 100 times between-25 ℃～70 ℃, and wherein programming rate is 3 ℃/min, and cooling rate is 1 ℃/min, and when reaching-25 ℃ or 70 ℃ in environment temperature, stops heating and cooling 30min.
Test result shows, no matter the material of shell 200 is polycarbonate or acrylonitrile-butadiene-phenylethylene polymkeric substance, no matter whether also have hole 212 on the drain pan 210, all can allow electrophoresis type display by motion test, store test and thermal cycle test, and still keep normal function.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
