More specifically, as shown in Figure 1B, in the present embodiment, the first touch control electrode layer 13 has many first axial electrode 13X, extended along first direction X.Second touch control electrode layer 16 has many second axial electrode 16Y, extended along second direction Y.These second axial electrode 16Y and these the first axial electrode 13X are electrically insulated.First direction X is preferably orthogonal with second direction Y substantially, but not as limit.In addition, contact panel 10 also comprises many cabling EL, and each cabling EL is electrically connected with corresponding touch control electrode respectively, to carry out touch control detection, but not as limit.
What deserves to be explained is, in the present embodiment, the material of the first touch control electrode layer 13 comprises nano metal line (at this for development) and in order to nano metal line is scattered in interior resin body, and the second touch control electrode layer 16 is transparent conductive material layer or conductive mesh layer.For example, second touch control electrode layer 16 can respectively by transparent conductive material such as tin indium oxide (indium tin oxide, be called for short ITO), indium zinc oxide (indium zinc oxide, be called for short IZO) formed with the composite bed of aluminum zinc oxide (aluminum zinc oxide, be called for short AZO), metal, transparent conductive material and metal or other applicable conductive materials.Above-mentioned metal can comprise metal material such as aluminium, copper, silver, chromium, titanium, the molybdenum wherein composite bed of at least one, above-mentioned material or the alloy of above-mentioned material, but not as limit, and its form can be latticed such as between 0.5 micron to 10 microns of live width, such as metal grill.Above-mentioned conductive material can comprise conducting particles, CNT, Graphene or silene, but not as limit, and its form can be latticed, such as conductive grid.
Furthermore, in the present embodiment, because development material has, line diameter ratio is high, radius is little, therefore can produce the effect of scattering (diffuse reflection) when external environmental light gets to development.In other words, in the present embodiment, the first touch control electrode layer 13 has mist degree.So, first touch control electrode layer 13 nearer by distance observer comprises development material, second touch control electrode layer 16 far away with distance observer adopts the material adapted of metal oxide or conductive mesh layer, when the external environmental light injecting contact panel 10 can be made to be reflected by each electrode pattern in the second touch control electrode layer 16, can be scattered via the nano metal line of the first touch control electrode layer 13.So, observer can be made not easily to observe electrode pattern in contact panel 10, and make touch control display apparatus 100 have good picture quality and display effect.In addition, in the present embodiment, appropriateness the mist degree of the first touch control electrode layer 13 can be improved, with the risk that the electrode pattern in contact panel 10 more can be avoided to be observed or to produce moire fringes (morie) phenomenon.For example, in the present embodiment, the mist degree of the first touch control electrode layer 13 can be greater than 1, it is preferred that mist degree can be greater than 1.2, more preferably, mist degree can be greater than 1.5.But it is noted that, the mist degree of the first touch control electrode layer 13 is excessive, easily causes image fog, therefore, mist degree is better is less than 3, and the best is less than 2.From another angle, the sheet resistance of the first touch control electrode layer 13 can lower than 150 Ω/, better can lower than 100 Ω/, the best can lower than 75 Ω/.The unit of sheet resistance also can be expressed as Ω/square or Ω per square.
In addition, in the present embodiment, because the first touch control electrode layer 13 adopts development material to be formed, even if therefore the second touch control electrode layer 16 adopts transparent conductive material such as metal oxide and is formed, the electrode pattern of contact panel 10 does not need all to use metal oxide (such as tin indium oxide) yet, and significantly can reduce cost of manufacture.In addition, when the second touch control electrode layer 16 is conductive mesh layer, the first touch control electrode layer 13 still by having development material reduces light that the metal grill via conductive mesh layer reflects and is reflected onto possibility in observer's eye, and therefore can improve the generation of moire fringes (morie) phenomenon, do not need design metal grill pattern with making or have much ado yet.
And, when the second touch control electrode layer 16 is conductive mesh layer, metal grill due to conductive mesh layer has low-impedance characteristic, and therefore the second axial electrode 16Y of the second touch control electrode layer 16 can in order to the touching signals drive electrode (Tx) as contact panel 10.On the other hand, although impedance and its mist degree of the first touch control electrode layer 13 are inversely proportional to, but, because the touching signals sensing electrode (Rx) of contact panel 10 is harsh unlike drive electrode (Tx) for the resistance requirements of electrode, therefore the first axial electrode 13X of the first touch control electrode layer 13 then can be used as the touching signals sensing electrode (Rx) of contact panel 10, and in order to arrange in pairs or groups mutually to carry out mutual capacitance type touch control detection with the second axial electrode 16Y, but the utility model is not as limit.
