“…Considering the actual process capacity, the thickness variation range is shown in Table 2. Based on Bending simulation, M in (SD Strain) in C-C is set as the optimization target, sensitivity analysis is conducted for four variables [4] , and key influencing factors are found and optimized. The simulation results of multivariate sensitivity analysis are shown in Figure 7.…”

This paper analyzes the design of the down border of the flexible OLED display, and studies the influence of the neutral layer and the sensitivity of SD strain of different stacks of Pad Bending in the narrow border area based on the finite element simulation. The neutral layer is located in the PI2 layer, and the order of the strain sensitivity of SD at Bending edge is MCL>Organic layer>PI1>PI2, MCL thickness has the greatest influence on SD strain. Through the stacking optimization design based on the sensitivity analysis results, the SD strain is reduced from 11.1% to 6.6%. Finally realize the industry's smallest R0.1mm Pad Bending design. Based on bending strain gauge and 25N static push test, SD strain is at a safe level and pass more than 50 times push tests. Narrow border products with R0.1mm Pad Bending can pass various environmental reliability tests to meet the environmental requirements of terminal products.

There are two problems in the traditional motion accuracy allocation process of mechanical transmission system: one is the error modeling process can not reflect the error formation mechanism of the system; the other is the influence of maintenance cost is ignored in the process of establishing the optimal allocation model of motion accuracy. Therefore, the meta-action theory is introduced in this paper and the meta-action unit is taken as the basic analysis unit, the error modeling of the mechanical transmission system is studied and the formation mechanism of the motion error is correctly analyzed. The factors of part manufacturing cost, assembly cost and maintenance cost of unit are comprehensively considered, and the comprehensive cost of mechanical transmission system is accurately evaluated by using multi-criteria decision making (MCDM) method. Then, based on the motion error model of mechanical transmission system, a multi-objective optimal allocation model of motion accuracy is established. The Pareto non-dominated solution set is solved by intelligent algorithm, and the optimal solution is selected by fuzzy set method to realize the allocation of motion accuracy of mechanical transmission system. Finally, the method described in this paper is illustrated by an engineering example.
