First to the 3rd basilar part 111a-113a can extend from the first to the 3rd side surface 110a-110c of transmission unit 110 respectively.
First to the 3rd basilar part 111a-113a can be formed by the material identical with transmission unit 110.It is to say, the first to the 3rd basilar part 111a to 113a can be formed by the material identical with transmission unit 110, such as PET, TAC film, PE, acrylic aldehyde or polyolefin etc..
First to the 3rd light shield 111b-113b can be arranged respectively on the surface of the first to the 3rd basilar part 111a-113a.Such as, the first light shield 111b is configurable on the first basilar part 111a, and the second light shield 112b is configurable on the second basilar part 112a, and the 3rd light shield 113b is configurable on the 3rd basilar part 113a.First to the 3rd light shield 111b-113b can be formed by the paint of extinction or coating, and makes by being respectively applied such paint or coating on the surface of the first to the 3rd basilar part 111a-113a.First to the 3rd light shield 111b-113b can absorb the ambient light on the side surface inciding flat panel display equipment 1000.
First to the 3rd reflecting element 111c-113c can be formed respectively on the first to the 3rd light shield 111b to 113b.First to the 3rd reflecting element 111c-113c can be formed by the paint of reflection light or coating, and makes by being respectively applied such paint or coating in the first to the 3rd light shield 111b-113b.First to the 3rd reflecting element 111c-113c configures towards flat display module 10, and goes out launching the luminous reflectance from flat display module 10, is therefore prevented from light and reveals through the side surface of flat display module 10.
Adhesive 114 can be configured to cover transmission unit 110 and the surface of the first to the 3rd reflecting element 111c-113c.Optical bonding film 100 is sticked to above flat display module 10 by adhesive 114.
According to another embodiment of the invention, optical bonding film 100 may be attached on flat display module 10 by self-adhesion, without using adhesive 114.In this article, self-adhesion note is that such a is pasted: by being connected mutually of two kinds of polymer and inorganic surfaces, does not uses cohesive force but utilizes the power of surface energy, such as, through moistening, magnetic force or electric charge between the two.According to another embodiment of the present invention, due to surface energy therebetween, optical bonding film 100 can be attached on flat display module 10 by self-adhesion.That is, the transmission unit 110 of optical bonding film 100 can be attached to the front surface of flat display module 10 by self-adhesion, and the first to the 3rd wing member 111-113 not only can be attached to the side surface of flat display module 10 but also can be attached to the part of rear surface of flat display module 10 by self-adhesion by self-adhesion.
Fig. 4 is the schematic, exploded perspective view of the flat panel display equipment 1000 of the optical bonding film 100 including Fig. 1 according to an embodiment of the invention.Fig. 5 is the perspective schematic view of the flat panel display equipment 1000 of Fig. 4.
With reference to Fig. 4 and Fig. 5, flat panel display equipment 1000 includes flat display module 10 and optical bonding film 100.
Flat display module 10 can be liquid crystal display or organic light-emitting diode (OLED) display apparatus.
Optical bonding film 100 can be attached to the front surface of flat display module 10 by self-adhesion.More specifically, flat display module 10 can include for showing the viewing area 10a of image and being connected to the pad regions 10b of external circuit (not shown).The transmission unit 110 of optical bonding film 100 is correspondingly arranged on the viewing area 10a of flat display module 10.First to the 3rd wing member 111-113 can be bonded together and cover side part and a part for rear surface for flat display module 10 with flat display module 10.Especially, the first wing member 111 side surface 10c to cover flat display module 10 bonding with flat display module 10 and a part for rear surface.Second wing member 112 side surface 10d to cover flat display module 10 bonding with flat display module 10 and a part for rear surface.3rd wing member 113 is bonding with flat display module 10 and covers the part facing side surface 10e and rear surface of flat display module 10.First to the 3rd wing member 111-113 can be bonding with the form of " C " with the side surface of flat display module 10 and rear surface.
But, it is formed without wing member in the bottom (corresponding to the bottom face 110d of Fig. 1) of transmission unit 110, and transmission unit 110 is configured to correspond to the viewing area 10a of flat display module 10.Correspondingly, optical bonding film 100 is not disposed on the pad regions 10b of flat display module 10, and pad regions 10b is to expose.
If flat display module 10 is liquid crystal display, then from the point of view of routine, liquid crystal panel and back light unit realize bonded to each other by gluing note two-sided tape in the rear surface of liquid crystal panel and the front surface of back light unit.But, optical bonding film 100 available transmission unit 110 according to the present embodiment and all front surfaces (being equivalent to the viewing area 10a of Fig. 4 and Fig. 5) of the first to the 3rd wing member 111-113 slurry crystal display device and side surface and rear surface, thus improve the adhesive strength between liquid crystal panel and back light unit.
First, second, and third light shield 111b, 112b and 113b and first overlay on the surface of the first to the 3rd wing member 111-113 to the 3rd reflecting element 111c-113c, and the first to the 3rd reflecting element 111c-113c is set in the face of flat display module 10.Thus, the light launched from the side surface of flat display module 10 is reflected by the first to the 3rd reflecting element 111c-113c, is therefore prevented from light and reveals through the side surface of flat display module 10.
