Description
Technical field
A kind of touch panel that can reduce Murray Effect, especially it is a kind of can while improving touch signal identification,
And effectively reduce interference fringe generation touch panel, as long as and induction electrode using film light shield manufacture, therefore be not necessary to using
Glass light shield, and cost of manufacture is effectively saved, it is not generated when being especially used together with the display panel of various mainstream sizes dry yet
Relate to striped.
Background technique
The metal grill of touch panel is bonded in application, be also easy to produce so-called interference line (Moire) with display panel, is influenced
Image display quality.The generation of interference line is the line width shadow because of metal grill pattern form, arrangement mode and metal grill
Several factors of light transmittance are rung to influence each other.When adjacent candy strip regularly arranges each other, i.e., optical interference line can be generated,
In order to effectively prevent the optical phenomenas such as interference fringe (interference fringes), such as so-called Murray Effect
(Moire effect).The line width of metal grill is fabricated between 1 micron to 3 microns, and adjustment metal grill
Shaped angles or arrangement mode are very effective method.
When another reason is then that touch panel is bonded with display panel, the metal grill of touch panel and display panel it is thin
Film transistor array (Thin-Film Transistor array, TFT array) (such as black matrix" (black matrix) or
Rgb pixel arrangement) it is all the arrangement of rule mesh trellis, therefore when the pattern overlapping of two rule mesh trellis arrangement, can also generate optics
Interfere line.
For the generation for avoiding or reducing interference line phenomenon, it can make the line width of conducting wire between 1 micron to 3 microns, in this way
Fine line width must make by high-resolution glass light shield, but involving great expense for glass light shield, and initial stage is caused to be opened
Hair and manufacturing cost increase.
Therefore it can be made through film light shield (ginseng Figure 1A), but film light shield 1a is low compared with glass light shield because of resolution ratio
Relationship, therefore relative to glass light shield, the phenomenon that having expansion with the infall of line online, and penetrate film light shield 1a via
Exposure development etch process, the metal grill 1b (such as Figure 1B) being made, line width only between 5 to 8 microns, and online with line
Infall then will form many node N, such as above-mentioned, larger with the line width that film light shield 1a is produced, therefore the area of node
It is larger, and each node is all the uniform shape of positive cross again, therefore is easy to happen diffraction phenomenon when light reaches at node, and
It influences light transmittance and seriously affects display effect.
Refering to Taiwan patent of invention notification number I601043 " with non-inductive function metal wire touch panel " a case,
It include mainly transparent substrates and two induction electrodes, two induction electrodes are opposite across transparent substrates, the metal grill of two induction electrodes
The metal wire of metal wire and non-inductive function respectively comprising tool inducing function, and opposite metal grill is also formed with mutually
Staggered lines；The purpose of the case is to avoid that diffraction effect occurs, and the technological means which uses is by each of metal grill
Grid area becomes larger (namely mesh-density becomes larger), and can be reduced the quantity of node, however it is to indicate to send out that number of nodes, which tails off,
The position of diffraction effect tails off out, but there is no reduced for the area of node itself, it would still be possible to generate diffraction effect.
In addition, the case incites somebody to action " metal wire of tool inducing function " with " metal wire of non-inductive function " in interlaced
When, although can constitute the not visible lattice of naked eyes on the whole, both above-mentioned itself is all the lattice of systematicness,
Therefore it is interlaced be still systematicness lattice, that is, interval between a metal wire is fixed, therefore is worked as
It, can be with the black matrix" (Black Matrix) and color filter layers of certain specifications when being bonded with the display panel of different size
Interfere line phenomenon, it is therefore necessary to which in addition the metal grill of different arrangement pitches is provided in design；But cost of manufacture can be brought
The problem of getting higher, while also having the problem of diffraction effect at node to be overcome.
Summary of the invention
The main purpose of the present invention is to provide one kind, and to improve touch-control again sensitive while reducing interference fringe and generating

Invention is mainly to provide a kind of reduction diffraction effect and betides the technological means of node, also just allows the two of configuration node
Each angle between lines is unequal, wherein each angle is in an appropriate angular range, but the angle of angle can be suitable
When determining in angular range with random number way, for example different included angles is selected, using makes the shape of each node slightly not
With and reduce the area at node, diffraction effect can so be effectively reduced and betide chance at node, therefore each node
And metal grill can't be just aligned with the black matrix" (Black Matrix) and color filter layers of display, that is,
Because of all non-single cross shape shape of shape of each node of the metal grill of present invention tool inducing function, therefore can be effectively reduced
The diffraction effect at node is betided, each lines for furthermore constituting metal grill also can be approximate straight with some curvatures, gradient etc.
The lines of line, so would not be just right with the black matrix" (Black Matrix) and colored filter of regular ordered arrangement
