The emissive layer, which itself can be composed of layers, is sandwiched between two electrode layers, wherein - is transparent to allow light to pass through. The transparent electrode layer, which is also The conductor layer 'is usually made of transparent and conductive indium tin oxide. However: the conductivity of the 4 material is incomparable with the conductivity of the metal, for example. The poor conductivity has a small surface. The area of the coffee device does not work.

The yak is supplied as a low-ohmic 7L cell unit that is provided in parallel with a plurality of intervals - current distribution. In addition, the grid lines can have different widths and/or thicknesses. In other words, the OLED device, * s ^ 该 the current in the emissive layer: 'can be selected by selecting the distance between adjacent lines and / or the structure of each line, that is, its width and / or thickness Adjustment. An outermost grid line is placed at a distance that is selected to be accurately controlled. The patterning step includes calculating that in a further preferred embodiment, a distance from the edge of the conductor layer is entered into the The internal dissipation of the current of the conductor layer is combined in a further preferred embodiment, current distribution. By calculating the current distribution of the OLED device (without grid cells), especially the emissive layer, the grid cells can be designed more accurately than the patterning step. The object of the present invention is also solved by a large area 〇LED device comprising at least an emissive layer; a transparent conductor I having a surface area; and a grid sheet 70' having a conductor layer provided thereon a plurality of grids on the surface area, the emissive layer having a predetermined current distribution, wherein the grid elements of the grid unit are unevenly disposed on the conductor layer to minimize the amount of 130410.doc 200908413 The non-uniformity of current distribution in the emissive layer. The OLED device of the present invention has the advantage that a larger uniform area with respect to the transmissive layer can be achieved. The unevenness of the large-area device is minimized by the grid unit of the present invention and the unevenly arranged frame elements so that the light rays on the entire surface area of the transparent conductor layer are uniformly hooked. Since the large area (10)D device with its emitter and conductor layers typically has MM turbulent distribution (no grid cells), the grid is compared to a grid using prior art solutions for horizontal or horizontal lines. 7L early can also be uneven. The grid unit preferably includes a plurality of grid elements that are electrically concomitant with each other and distributed throughout the surface area. The grid elements are typically low ohmic components for shunting purposes, such as metal lines, triangles, rectangles, hexagons, or any other two-dimensional structure. Of course, the grid unit can include grid elements of different configurations, such as a combination of lines and rectangles. Furthermore, the grid elements of the grid unit may have an unordered structure and, for example, 'not-continuously continuous. Moreover, the structures of the grid elements can be different with respect to width and/or thickness, and thus are not uniform. The features and advantages of the invention are as described in the following description and the drawings. It should be understood that the above-mentioned characteristics of the transfer of IJt 33⁄4 -ρ· and the characteristics of the invention can not only be used for the combination of ..., delay, and deduction, but also in other combinations or Used independently.

The conductor layer 18 is made of a conductive transparent material such that light generated in the emissive layer can pass through the conductor layer. The cathode layer 14 and the transparent conductor layer 18 serve as electrodes, which are respectively surface-contacted with a driving unit or a negative electrode and a positive terminal 3 6 and 34 of a power source. The transparent conductor layer 18 comprises a transparent conductive oxide, such as oxidized steel tin (ITO), the conductivity of which is generally sufficient to produce the necessary light emission to illuminate a small OLED but the conductivity is insufficient to produce The necessary current to illuminate a large area of the OLED. The conductor layer 18 is provided with a "button" 7L. The tree element 2 includes a plurality of grid elements 22' which are low-ohmic shunt elements and are distributed over the surface area 46 of the conductor layer 18. As shown in Fig. 2, the grid sheet U includes grid elements 22 in the form of metal wires 24. These metal wires 24 having good conductivity are used to shunt the transparent conductor, which is inherently poor. The grid elements are distributed on the surface area 导体 of the conductor layer 18 according to a pattern in which the dome 描 is described below. 130410.doc -10- 200908413 In the embodiment of Fig. 2, The equal metal wires 24 are placed on the conductor layer 18 in parallel with each other, wherein the distance d between adjacent wires 24 is gradually decreased from the left side to the right side of Fig. 2. In other words, the distance between the leftmost outermost lines 24 It is indicated by d 1 that it is greater than the distance d2 between the outermost outer lines 24 of the right side. Figure 2 also shows that all the lines 24 are electrically coupled to the edge portion 2 of the grid unit, and the display is on the right The edge of the conductor layer 18 on the side and the first-gold from the right side There is a gap 42 between the lines 24. The gap between the transparent conductor layer and the line 24 allows for precise adjustment of the inner bank of the current entering the conductor layer 18. As already mentioned above, the grids The form and pattern of the grid element 22 is based on the OLED installation of the gridless unit, and is particularly designed with its emission layer "electricity: distribution characteristics. That is, the emissive layer 16 having the conductor layer 18 has a generally uniform current distribution (which is not coupled to the grid unit 2) for large surface areas. In order to determine the pattern of the grid elements 22, the device of the gridless unit, and in particular the current distribution of the emissive layer 16, is theoretically or practically calculated. The grid cells having grid elements are then designed such that the non-uniformity of the current distribution is minimized by the grid elements. When the conductor layer 18 and the grid unit 2 are combined, the current distribution in the emissive layer 16 is uniform and uniform. The result is that the light generated by the layer is uniform over the entire surface area. 130410.doc -11 - 200908413 Therefore, the ZH Hai special frame element is used for 曰丨π + 丄 丄 U Ί dry forging to reduce the unevenness of current distribution in the large-area emission layer, 杳ΙΗ χ ^ ^ , a sex to achieve a uniform light production.
