Description

Display floater and electrode base board thereof and electrode panel
Technical field
The present invention relates to a kind of display floater and electrode base board thereof and electrode panel, be meant a kind of display floater of flat-panel screens, the electrode base board of flat-panel screens and the electrode panel of flat-panel screens especially.
Background technology
As shown in Figure 1, the electrode base board 4 of present employed flat-panel screens has a substrate 41, an electrode layer 42 and a conductor layer 43, and electrode layer 42 is formed on the substrate 41, and conductor layer 43 is formed on the electrode layer 42.Wherein, the material of conductor layer 43 is selected from metal or its alloy of low-resistivity, and is general commonly used as silver alloy etc.
In the processing procedure of flat-panel screens, it utilizes etching solution that the conductor layer in the electrode base board 4 43 is etched into the pattern of actual required conductor wire or the pattern of additional conductive line, then on electrode base board 4, form luminous zone and comparative electrode again, engage with driving element (as chip for driving) more at last to form display floater.
Wherein, on electrode base board 4, form in the conductor wire pattern or the processing procedure of additional conductive line chart sample, one photoresist layer 5 is formed on the conductor layer 43 (silver alloy), then a light shield 6 with pattern is arranged on the photoresist layer 5, the while is also shone a ultraviolet light (UV light), as shown in Figure 2 again, next carry out development step again, at last, utilize etching solution to carry out etching again, so that conductor layer 43 is etched into the pattern of required conductor wire; Yet, the situation of oxidation (blackening) takes place in conductor layer 43 (silver alloy) easily because of irradiating ultraviolet light, cause the resistance value of conductor layer 43 to raise and and photoresist layer 5 between the decline of tack, and in follow-up processing procedure, driving element (chip for driving) pressurizing attaching is on conductor wire, already oxidised conductor wire will be difficult for fitting with driving element, may cause the phenomenon of the driving element that comes off, and further influence the stability of display floater.In addition, when display floater uses, conductor wire also easily with extraneous oxygen or reaction of Salmon-Saxl, add simultaneously electric current by the time heat that produced, and cause the conductor wire oxidation even burn.
In view of this, general its employed metal conductive wire of active drive flat-panel screens (as AMLCD) of using mostly is the alloy of some transition metal such as manganese (Mo), chromium (Cr) or tantalum (Ta) greatly.Its thin film deposition thickness can not too thickly just can obtain pasting property of film (step-coverage) preferably when making these metal conductive wire.Yet thin metal conductive wire will cause the resistance of conductor wire to raise, and cause the RC-delay of signal to become big.Therefore, the big young pathbreaker of the two-d display panel of these transition metal mades is limited.So,, must develop the metal conductive wire processing procedure or the material that to have ultralow resistance in order to make the large scale two-d display panel.
And,, must adopt the metallic film of thicker and broad in order to obtain lower resistance from the angle of metal conductive wire processing procedure.But its shortcoming of thick metallic film forms (pinhole formation) for producing relatively poor pasting property and hole.Though, so will cause the increase of processing procedure cost again at present to use special oblique angle etching (taper etching) processing procedure to be improved.What is more, and the metallic film of broad then not only reduces aperture ratio of pixels but also increases the parasitic capacitance (parasitic capacitance) of conductor wire again.Therefore, metallic film processing procedure thicker and broad is also infeasible.
Recently once there was proposal to improve pasting property and reduce hole formation with the metal conductive wire processing procedure of planarization.But the processing procedure of planarization needs the extra fabrication steps and the result of material and planarization will increase parasitic capacitance value again.So comprehensive above result is more feasible from the essence of improving material.
For adapting to above requirement, therefore aluminium at first be developed because have the low resistance and the simplification of processing procedure.But because aluminium is easy to generate protrusion (hillock) under the situation that higher temperatures and big electric current flow, the situation that causes conductor wire to produce short circuit or open circuit causes display floater to produce the problem of reliability.And copper has lower resistance, is another better Material Used.But copper is relatively poor for the tackness of glass substrate, easily oxidation and be not easy etching of surface.Therefore, modulation on the processing procedure or the change on the composition are inevasible.So, processing procedure cost and complexity increase significantly, so and do not meet the requirement of a large amount of manufacturing production Organic Light-Emitting Device.
In addition, in the processing procedure of TFT-LCD (Thin Film Transistor-LCD), utilize the three-layer metal structure of chromium/aluminium/chromium or molybdenum/aluminium/molybdenum to be used as the material of conductor wire, to avoid producing above-mentioned problem.But, in the making of this kind conductor wire, must use two kinds of different etching solutions.At the beginning, utilize first etching solution etching upper strata chromium (molybdenum) metal earlier, then utilize the second etching solution etching aluminum interlayer metal again, utilize first etching solution etching lower floor chromium (molybdenum) metal at last again, that is must carry out three times etching step, fabrication steps complexity not only, and also increase whole cost, and be not suitable for the application on the actual industrial.
Summary of the invention
Because above-mentioned problem; the purpose of this invention is to provide a kind of the have display floater of two-layer protective layer and electrode base board and electrode panel that display floater is used; these protective layers can guardwire layer (conductor wire) and make conductor layer be difficult for oxidation to burn, simultaneously the shape of the conductor wire that also may command etched.
