Abstract
The utility model discloses an ITO film and a transparent touch key with the same. The ITO film is divided into at least two micro ITO films along a direction perpendicular to the bending direction, and the edges of two adjacent micro ITO films are connected through conductive materials. Since the ITO film is divided into at least two ITO films, bending resisting critical radius of the ITO film is reduced, deformation of the ITO film structure is reduced, conductivity failure caused by ITO film damage can be avoided, volume of the ITO film is reduced, and accordingly manufacturing cost of the ITO film is reduced correspondingly.
Description
Technical field
The utility model relates to a kind of ito thin film and has the transparent touch key-press of this ito thin film.
Background technology
Tin-doped indium oxide (Indium Tin Oxide is called for short ITO), ito thin film is a kind of n N-type semiconductor N material, its electrical conduction mechanism is the migration of charge carrier (electronics) between lattice.Have high conductance, high visible light transmissivity, high mechanical hardness and chemical stability by ito thin film, so it is the most frequently used thin-film material of transparency electrode of LCD (LCD), plasma display (PDP), electroluminescent display (EL/OLED), touch-screen (Touch Panel), solar cell and other electronic instrument.
When applying external force and act on ito thin film and significant change takes place, in case intrinsic film microstructure is destroyed, will cause the carrier mobility passage to be affected, show as the variation of film resiativity on the macroscopic view; Changes of microstructure comprises peeling off between film self fracture, film and the substrate, coming off of rete even, and these change and generally all occur in the zone that film edge and growth defect iso-stress are concentrated relatively.
Therefore, the utility model provides a kind of ito thin film and has the transparent touch key-press of this ito thin film, and it can improve the bending resistance folding endurance of ito thin film, improves the reliability of ito thin film.
The utility model content
The utility model provides a kind of ito thin film, and it can improve the bending resistance folding endurance of ito thin film, solves the problem that causes the ito thin film conductive capability to lose efficacy because of bending, improves the reliability of ito thin film at ito thin film.
The utility model reduces the bend resistance critical radius of ito thin film by ito thin film being divided into the little ito thin film of at least two fritters, reduces the deformation quantity of ito thin film structure, reduces the conductive capability failure phenomenon that causes because of the ito thin film damage.
The utility model has reduced the volume of ito thin film, thereby has reduced the manufacturing cost of ito thin film.
The utility model is achieved in that
A kind of ito thin film this ito thin film is divided at least two little ito thin films with it on perpendicular to overbending direction, and the edge of adjacent two these little ito thin films connects by electric conducting material.
Preferably, this ito thin film also comprises silver slurry line, by this silver slurry line will this a plurality of little ito thin films the bottom connection.
Preferably, this ito thin film is divided into four little ito thin films with it on perpendicular to overbending direction.
The utility model also provides a kind of transparent touch key-press, it is applied in the air-conditioning electric-control system, this transparent touch key-press includes ito thin film, this ito thin film is divided at least two little ito thin films with it on perpendicular to overbending direction, and the edge part of adjacent two these little ito thin films connects by electric conducting material.
Preferably, this ito thin film also comprises silver slurry line, by this silver slurry line will this a plurality of little ito thin films the bottom connection.
Preferably, this ito thin film is divided into four little ito thin films with it on perpendicular to overbending direction.
Preferably, this transparent touch key-press also comprises flexible circuit board, and described ito thin film is connected by electric conducting material with flexible circuit board.
Technique effect of the present utility model:
A kind of ito thin film of the utility model and have the transparent touch key-press of this ito thin film, the bend resistance performance that it has improved ito thin film has solved ito thin film because of the crooked problem that causes conductive capability to lose efficacy.
Description of drawings
Fig. 1 is the utility model ito thin film and the structural representation with transparent touch key-press of this ito thin film.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated:
As shown in Figure 1, wherein, the direction of arrow is the overbending direction of ito thin film.The transparent touch key-press of the utility model, it includes 6 key areas 1, reaches flexible PCB 3, each key area 1 includes ito thin film, this ito thin film is divided into four little ito thin films 10 with it on perpendicular to overbending direction, adopt silver slurry line 2 that it is connected in series in the bottom of these four little ito thin films 10, last, by electric conducting material ito thin film is connected with this flexible circuit board 3 again, in the present embodiment, electric conducting material is preferably silver slurry line 20.
In the utility model, the piece number of little ito thin film that this ito thin film is divided into is many more, and its bend resistance performance is just good more, and the utility model preferably is divided into ito thin film four little ito thin films.
Only be specific embodiment of the utility model below, do not limit protection range of the present utility model with this; Any replacement and the improvement done on the basis of not violating the utility model design all belong to protection range of the present utility model.
