Abstract
The invention discloses an ITO (Indium Tin Oxide) thin film and a transparent touch key provided with the same. The ITO thin film is divided into at least two micro-ITO thin films in a direction which is vertical to a bending direction; and the edge parts of the two adjacent micro-ITO thin films are connected through a conductive material. According to the invention, the ITO thin film is divided into at least two micro-ITO thin films, therefore the anti-bending critical radius of the ITO thin film is reduced, the transformation of the structure of the ITO thin film is decreased, and the phenomenon that the conductive capacity is ineffective because the ITO thin film is broken is reduced. The volume of the ITO thin film is reduced so that the manufacture cost of the ITO thin film is correspondingly cut down.
Description
Technical field
The present invention relates to a kind of ito thin film and have 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 type, semiconductor 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 present invention 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.
Summary of the invention
The present invention 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 present invention reduces the bend resistance critical radius of ito thin film through 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 present invention has reduced the volume of ito thin film, thereby has reduced the manufacturing cost of ito thin film.
The present invention is achieved in that
A kind of ito thin film is divided at least two piece little ito thin films with it with this ito thin film on perpendicular to overbending direction, and the edge of adjacent two these little ito thin films connects through electric conducting material.
Preferably, this ito thin film also comprises silver slurry line, through 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 present invention 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 through electric conducting material.
Preferably, this ito thin film also comprises silver slurry line, through 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 said ito thin film is connected through electric conducting material with flexible circuit board.
Technique effect of the present invention:
A kind of ito thin film of the present invention 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 ito thin film of the present invention and the structural representation with transparent touch key-press of this ito thin film.
Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are 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 present invention; 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, through 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 present invention, 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 present invention preferably is divided into ito thin film four little ito thin films.
Be specific embodiment of the present invention only below, do not limit protection scope of the present invention with this; Any replacement and the improvement on the basis of not violating the present invention's design, done all belong to protection scope of the present invention.
