Grating Light Modulator (GLM) based on micro-Electro-Mechanical systems (MEMS) is applied in projection *** principle of GLM is introduced in the *** factors influencing the performance of passive matrix addressing for GLM are analyzed in *** the response frequency and the driving voltage are relative to the elastic coefficient of *** the elastic coefficient is larger,both response frequency and driving voltage are *** is indicated by analysis that in a m×n array when an all-selected pixel is actuated by a voltage V0,the voltages of half-selected pixel in row and column are respectively V0(m-1)/(m+n-1) and V0(n-1)/(m+n-1),and non-selected pixel's voltage is V0/(m+n-1).Finally,the operating voltage and the pull-in voltage are respectively 7.8V and 8.5V measured by the experiment,and these experimental values are very approximate to the theoretical *** GLM is actuated by a 7.8V square-wave voltage with lkHz frequency,the rising-edge time and the falling-edge time are respectively about 46.59μs and 44.77μ*** experiments indicate that the response frequency of GLM is about ***,the other experiment validates the correctness of crosstalk in a 16×16 GLM *** experiments provide a theoretical basis for improving the driver of GLM.
