- Title:Application of Mura Index Methods to L0 Grey State
- Jaegeon You and Qian Jia (BOE Tech. Group Co., Ltd., China)
Abstract: Recently, two groups have reported the Mura index calculation method of leveling on the screen in the FPD products [ref. 1&2]. They suggested quantitative methods with human sensitivity of spatial frequency for over 20% brightness of full white pattens. This paper presents results of these application to 0% brightness of full white state in ADS LC mode. In dark state, L0 grey image was taken by conventional camera, RGB was transferred to XYZ color value [3], through noise filter, changed to opponent color and then through MTF(S-CIELAB) spatial filter [4], retransferred to XYZ and finally transferred to La*b*. Ygen[ref. 1]?and E index [ref. 2]? were calculated?for L0 grey mura image in ADS LC mode.
