Description
Technical field
The present invention is relevant for the electrode structure of a kind of electricity slurry flat-panel screens (PDP), and the transparent electrode structure that particularly consumes relevant for a kind of cpable of lowering power.
Background technology
Because multimedia developing rapidly makes the user more and more high to the acousto-optic equipment requirements of periphery.(Cathode Ray Tube, the CRT) display of type because volume is too huge, were being bragged about in light, thin, short, the little epoch now, did not gradually apply demand for Chang Yong cathode ray tube or title iconoscope in the past.Therefore, there are many flat-panel screens technology to be developed in succession in recent years, as LCD (LiquidCrystal DisPIay, LCD), electricity slurry flat-panel screens (Plasma Display Pane, PDP), and Field Emission Display (Field Emission Display FED), becomes the main flow of following display gradually.Wherein, be subjected to gazing at greatly as full-color display unit with electricity slurry flat-panel screens (PDP).
In color PDP, produce ultraviolet ray by gas discharge, excite phosphor body to launch visible light and form display effect.According to the discharge mode of PDP, color PDP simply can be divided into AC type (AC) and once-through type (DC) two classes.In AC type PDP, on electrode, be coated with protective layer, this makes AC type PDP have long useful life and higher display brightness.Therefore, in display effect, luminous efficiency and on useful life, AC type PDP generally is better than once-through type PDP.
Usually in AC type PDP, three-electrode structure be can use, shared electrode, scan electrode (X electrode, Y electrode) that is positioned at upper substrate and the bit address electrode that is positioned at infrabasal plate comprised.Three-electrode structure is the surface discharge form, and switches or keep discharge by applying voltages to bit address electrode.Figure 1 shows that the upper substrate electrode structure 100 of general PDP, both all comprise the transparency electrode 102 of narrower auxiliary electrode 101 (Bus electrode) and broad traditionally can be divided into common electrode (common electrode) and scan electrode (scanelectrode), become the straight horizontal stripe-arrangement, and with 103 one-tenth vertical relations in group next door of infrabasal plate, between two adjacent region of discharges and absence of discharge district, deceive line 104 in addition and handle, promote the brightness contrast of traditional electrical slurry flat-panel screens.
Yet, because the area of its transparency electrode of traditional panel is excessive, produce bigger electric capacity, therefore when having only, PDP shows when hanging down GTG that though brightness is very low, it is quite big to keep the power (Pvs) that voltage (Vs) consumed, because excessive transparency electrode area, can make and keep in the charge and discharge process of voltage between upper plate electrode, produce bigger power consumption, the influence surface plate efficiency.
Summary of the invention
Main purpose of the present invention is to provide a kind of transparent electrode structure, and it has less transparency electrode area, can effectively reduce panel capacitance, reduces power consumption.

Another purpose of the present invention is providing a kind of transparent electrode structure, and it can effectively keep strength of discharge according to the design of PDP discharge mode.
The invention provides a kind of transparent electrode structure, at least comprise that a main body is connected block with two, wherein this main body is joined by this two branch line that connects block and comb electrode, and it is protruding in the structure of discharge centers to form main body, wherein leaves a hollow out zone between the main line of transparency electrode and comb electrode.
Technical scheme of the present invention is achieved in that a kind of transparent electrode structure of electricity slurry flat-panel screens, this electricity slurry flat-panel screens has a plurality of luminescence units at least and is positioned between upper and lower base plate, and having a main line, a comb electrode crosses those luminescence units, and a plurality of branch lines are from this main line vertical extent and between those luminescence units, and this transparent electrode structure comprises at least:
A plurality of main bodys, each those main body are positioned between corresponding two adjacent branch lines and this main line; And
A plurality of connection blocks, lay respectively at the both sides of those main bodys, wherein each those main body can see through and is positioned at two of both sides and connects blocks and join with corresponding two branch lines respectively, and each those main body be positioned at both sides two be connected block and form the shape that arches upward so that the protruding discharge centers of each those main body to luminescence unit.
Leave a hollow out zone between the main line of this transparent electrode structure and this comb electrode.
The width of this main body is about 20% to 60% of luminescence unit spacing (cell pitch).
The ratio that this body thickness accounts for this luminescence unit pel spacing (pixel pitch) is about 5% to 30%.
Those main bodys are connected block with those material comprises indium tin oxide.
Because transparency electrode of the present invention forms the shape that arches upward to discharge centers place projection according to discharge mode, therefore can improve its discharging efficiency.On the other hand, leave a hollow out zone between the main line of transparency electrode of the present invention and comb electrode, therefore significantly reduce the area of transparency electrode, effectively reduce panel capacitance.
