The IR‐drop in the full AMOLED display panel caused by the pixel current is simulated within the mainstream SPICE toolkit to evaluate the display uniformity. Each electrical part of the display panel is simplified and equalized to allow the SPICE doing the very large scale calculation. The implementation of the full panel simulation and the results give better understanding of AMOLED panel design.

The preparation of Mg/SiC fiber precursor is the key process for the application of SiC fiber in the Mg alloys. Electrochemical deposition method was firstly adopted for the preparation of Mg/SiC fiber precursor in the LiCl-KCl molten salt. However, metal Li will be deposited prior to the deposition of Mg to form Li-C alloys with the carbon layer on the surface of SiC fiber due to the under potential deposition of Li+ ion. A Cu intermediate layer was introduced to avoid the formation of Li-C alloys, so that SiC fiber could be stable in a wide electrochemical window in the LiCl-KCl molten salt. A thin Cu layer was coated on SiC fiber using chemical plating method. The effect of NaOH concentration on the Cu coating was investigated and bright Cu coating was obtained. The electrochemical deposition process of Mg2+ ion was investigated through cyclic voltammetry and the detailed deposition parameters were obtained. Mg/SiC fiber precursor was prepared using pulse current electrodeposition method following the deposition parameters obtained by cyclic voltammetry. The morphology and microstructure of SiC/Mg fiber were explored through SEM. After the optimization of electrodeposition condition, compact and even Mg layer were prepared on SiC fiber.
