Description

Display

Technical field

The present invention is relevant with display, refers to have the big anti-display of ability that falls especially.

Prior art

Touch control display device (touch panel display) has been widely used in various portable electronic devices, for example on the product such as Smartphone or panel computer.And because the problem that portable electronic devices will inevitably be dropped because of carelessness in the face of the user, so touch control display device in process of production, must fall to falling test by one, the ability when guaranteeing the product withstand shock.

See also Fig. 1 (a), it is the synoptic diagram that touch control display device falls to falling test, wherein expresses touch control display device 1 and impacts to the plane 19 state with its corner 18.

See also Fig. 1 (b) again; it is the part diagrammatic cross-section through above-mentioned touch control display device 1 after falling to falling test; wherein the surface of display panel 10 is pasted with polaroid 11, and substratum transparent 12 is covered in the surface of this polaroid 11 again, and last transparency protected 13 is covered on this substratum transparent 12.Wherein, cause transparency protected 13 and 11 generations of polaroid bubble 14 at last because the distortion power of transparency protected 13 distortion will drive substratum transparent 12 to be peeled off with 11 moments of polaroid and air is entered.And how to improve these shortcomings, be exploitation fundamental purpose of the present invention.

Embodiment

But go out by the stress deformation synoptic diagram clear view among Fig. 2; cause the bending scope 139 of transparency protected 13 distortion when reaching the corner of polaroid 11 when falling to falling test; all peeling forces all concentrate in end points 17 attaching place on every side, and this makes that producing the probability of peeling off with polaroid 11 for transparency protected 13 heightens.

At the problems referred to above; the present invention will use the shape in polaroid corner always and improve; as Fig. 3 (a) (b) shown in the synoptic diagram of first preferred embodiment of the present invention; wherein Fig. 3 (a) is the part diagrammatic cross-section of first preferred embodiment of display of the present invention; display includes display panel 30; it can comprise upper substrate 308 and the infrabasal plate 309 that is superimposed; upper substrate 308 surfaces of display panel 30 are pasted with polaroid 31; substratum transparent 32 is covered on this polaroid 31; be that substratum transparent 32 is covered in the surface of polaroid 31 away from upper substrate 308; transparency protected 33 are covered on this substratum transparent 32, and wherein the area of polaroid 31 is less than this transparency protected 33.The edge of substratum transparent 32 is between the edge and this edge of transparency protected 33 of this polaroid 31.For example as shown in Fig. 3 (a), the edge of substratum transparent 32 can exceed the edge of polaroid 31.Perhaps also can be as shown in Fig. 3 (d), the edge of substratum transparent 32 roughly trims with the edge of polaroid 31.

And the top view shown in Fig. 3 (b) as can be known, the present invention is with the corner corner cut of polaroid 31 and make polaroid 31 have at least one truncated portion 310, and the neighboring area 302 that display panel 30 mainly can be divided into a viewing area 301 and center on this viewing area 301, this neighboring area 302 comprises at least one corner part 3021, and the corresponding corner part 3021 in the position of this truncated portion 310 is to expose corner part 3021.So design can improve transparency protected 33 and the concentrated situation of 31 peeling forces of polaroid when falling to falling; make the peeling force of transparency protected 33 corner bending be dispersed in all attachings place in the side cut 311; concentrating on end points 17 with peeling force among Fig. 2 compares; the design of polaroid 31 corner cuts of the present invention concentrates in the side cut 311 peeling force; so can be linear side cut 311 opposing peeling forces, make to fall to falling the moment that is produced and peel off probability and significantly reduce.And with polaroid 31 corner corner cuts; also can make transparency protected 33 and the attaching edge in polaroid 31 corners moves in more past because of the relation of corner cut; therefore the zone of transparency protected 33 bending needs the wider attaching edge that could arrive transparency protected 33 and polaroid 31, just needs bigger to fall to falling that impulsive force just is enough to pull substratum transparent 32 and generation is peeled off.It should be noted that though above-mentioned only to have a truncated portion 310 with polaroid 31 be example, the number of truncated portion 310 is not limited thereto, for example, the also visual demand of the number of truncated portion 310 and be designed to 2～4.

But if the mode of corner cut is shown in Fig. 3 (b), can find out in corner cut and level or vertical edge junction place and have drift angle a and drift angle b, and with the variation of land wrestling degree, peeling force still might concentrate in drift angle a and drift angle b attaching place on every side, therefore still may have the problem that peeling force is comparatively concentrated.Even point to the arrow of drift angle a and drift angle b among the direction that produces of peeling force such as the figure, still have peel off in drift angle a and drift angle b place possible.

So the present invention reintroduces second preferred embodiment shown in Fig. 3 (c), present embodiment can change the rescinded angle shape shown in Fig. 3 (b) into arc rescinded angle 39 by angle.Do not have sharp-pointed drift angle owing to each position on the circular arc of arc rescinded angle 39 and with the edge junction place; that is; arc rescinded angle 39 makes the peeling force of transparency protected 33 corner bending be dispersed in arc all attachings place on 390 the camber line of cutting edge; therefore can solve the problem that above-mentioned peeling force concentrates on drift angle a and drift angle b; can more improve the ability of display antistripping, make to fall to falling the moment that is produced and peel off probability and more reduce.

In sum, after the present invention improves common technology, can eliminate the shortcoming of common technology effectively, successfully reach the fundamental purpose of case of the present invention.And above-mentioned display panel 30 can be a touch-control display panel, for example be display panels, Plasmia indicating panel (the plasma display panel that includes touch control unit, PDP), organic LED display panel (organic light emitting diode display, OLEDdisplay) or electrophoretic display panel (electrophoretic display, EPD) etc.32 of above-mentioned substratum transparents can be finished with optics glue-line (OPTICAL CLEAR ADHESION), and wherein substratum transparent 32 for example is a transparent adhesive tape diaphragm.In addition, can select glass sheet or acryl sheet for use for above-mentioned transparency protected 33, but be not limited thereto, can use the higher protective material of other hardness in addition.Though therefore the present invention discloses as above with preferred embodiment; right its is not in order to limiting the present invention, anyly is familiar with present technique field person, without departing from the spirit and scope of the present invention; when can doing a little change and retouching, so protection scope of the present invention is when being defined by claims.
