硅基OLED微显示双模融合扫描算法
Dual-mode fusion scanning algorithm for OLED-on-silicon microdisplay
摘要
Abstract
To solve the problems of low greyscale nonlinearity,greyscale inversion and low precision in the digital driving of OLED-on-silicon microdisplay,a dual-mode fusion scanning(DMFS)algorithm is proposed in this paper.The sub-frames are divided into high bit subframe(HBSF)and low bit subframe(LBSF),in which HBSF adopts progressive luminescence(PE)mode to ensure luminous efficiency,while LBSF adopts synchronous luminescence(SE)mode to achieve fine brightness regulation and linearity correction.Experiments on a 2 560×2 560×3@90 Hz full-color microdisplay show that DMFS significantly improves greyscale linearity,reduces greyscale inversion points of 13 872,and reduces the root mean square of luminance error of DMFS-4 and DMFS-6 by 96.63%and 99.31%compared with the 25-subfield method.Furthermore,DMFS can achieve a minimum brightness accuracy of 0.076 cd/m² and expand the effective mapping coverage range of gamma to 253 greyscale.The DMFS algorithm achieves significant advancements in display linearity and greyscale precision,effectively enhancing image detail performance and immersive visual experience,providing a feasible solution for high-precision digital driving in near-eye display devices.关键词
