用数模结合的方法实现AM-OLED的白平衡
Achievement on White Balance for AM-OLED
摘要
Abstract
As using digital algorithms alone will lead to lower gray level while the use of simulation algorithms alone is difficult to achieve fine-tuning or the circuit is too complex,a method of combining digital and analog is proposed to achieve AM-OLED white balance by using analog simulation and digital adjustment to make up for these shortcomings.Analog simulation is determined by the drive voltage according to the three primary colors.Digital adjustment using LM optimized BP learning algorithm fits the curve of the transmission characteristics of the OLED.Compared with traditional BP algorithms,learning speed of this algorithm is improved,the convergence of the network is accelerated,and it avoids a system into a local minimum.The simulation results and the display results show that this method achieves the white balance of the image.关键词
