Zinc oxide (AluminumZineOxide; = 0) is used as the anode on the substrate, and the cathode of the low work function metal or alloy is used as the control structure of the light emitting pixel. For π-viewing semiconductor or organic electroluminescent display devices, metal complexes are often used as the material of the wires. Although the road metal itself has certain electrical characteristics, good corrosion resistance, and low material costs, but when the metal is used as a conductive film electrode, the resistance of the road itself is higher than that of copper. Therefore, it is difficult to achieve low-voltage driving of the light-emitting layer to display the image. Therefore, the best control of the image rendering cannot be achieved. At the same time, its resistance is slightly higher, which will cause power consumption due to heating. Increasing the use efficiency of 4, 1 source, and during operation, it will make the flat display temperature, and will affect the hair between the conductive film anode and the low-power function cathode.
