Description

Contact panel

Technical field

This utility model relates to a kind of contact panel, can reduce or avoid the contact panel of the sensing metal grill interfering stricture of vagina (Moire) to occur particularly to one tool。

Background technology

At present, touch technology has been widely used in the display device of various electronic product, in order to user utilizes touch control manner to manipulate the start of this electronic product。Contact panel not easily depending on recognizing, is generally adopted tin indium oxide (ITO) to form transparency electrode to make the electrode of its touch area。But along with the application of contact panel develops towards large-sized direction gradually, it is slower that the technology using indium tin oxide transparency electrode also exists that resistance is relatively big, touch-control responds speed, needing multiple tracks processing step and the more high technical problem of cost of manufacture, therefore metal grill (MetalMesh) senses electrode and is then developed replacing the application of indium tin oxide transparency electrode。

But, when the metal grill of contact panel and display floater laminating application, it is easily generated so-called interference stricture of vagina (Moire), affects picture display quality。The generation interfering stricture of vagina is primarily due to metal grill pattern form and is caused, and when adjacent candy strip arranges each other regularly, namely can produce optical interference stricture of vagina。Additionally, when the striped that the live width of metal grill is more thick or adjacent overlap or cross point and when making candy strip thickness each other increase, will easily cause and interfere stricture of vagina generation。When another reason is then contact panel and display floater laminating, thin film transistor (TFT) array (the Thin-FilmTransistorarray of the metal grill of contact panel and display floater, TFTarray) it is all the arrangement of rule mesh trellis (as black matrix" (blackmatrix) or rgb pixel arrange), during the pattern overlapping that therefore two rule mesh trellis arrange, also can produce optical interference stricture of vagina。

For avoiding or reducing the generation interfering stricture of vagina phenomenon, the pattern of the metal grill of current contact panel arranges generally according to the thin film transistor (TFT) array of display floater with stripe shape, and be designed as the micro-line of the metal by a plurality of linearity and constituted lattice in the way of interlocking and be regularly arranged, thereby to increase visibility。For example, the first micro-line of metal that metal grill comprises a plurality of linearity extends in a first direction and arranged in parallel, and the second micro-line of metal of a plurality of linearity extends and arranged in parallel in a second direction, wherein the first micro-line of metal of a plurality of linearity and the second micro-line of metal of a plurality of linearity are mutually isolated and are crisscross arranged to form a touch-control array。But, the metal grill of the contact panel of prior art must have good coordinating could reduce the generation interfering stricture of vagina with the thin film transistor (TFT) array of display floater, therefore the space between the micro-line of metal of a plurality of linearity of metal grill need to through fine design with staggered angle, cause the difficulty in design, and easily reduce visibility because of metal grill design error。On the other hand, if using random pattern to be designed to deal with interfering stricture of vagina problem, but likely because mesh design aperture opening ratio is not of uniform size and skewness, and the phenomenon of brightness irregularities is produced。When multiple random pattern combination with one another, also it is likely in its interface intersection place make because of node location change at random not easily to splice between random pattern or produce to interfere stricture of vagina etc.。

Therefore, how to develop a kind of tool and can reduce or avoid the contact panel sensing metal grill and method for making thereof of interfering stricture of vagina (Moire) to occur to solve prior art problem encountered, actually have problem to be solved。
