8 DLPP icotechnologyoffersseveralkey advantagesthat makeit a greatfit for ScreenlessDisplay: Highopticalefficiency:DLPP icotechnologycan workwith any light sourceincludingLEDs,lasers,laser-phospho ror lampand offersvery high resultis a high brightnessdisplaywith low powerconsumption,whichis a particularlygoodfit for high brightnessdisplayapplicationssuchas powerconsumptionalso enablesbatteryoperationfor a cable-lessexperience. Widechoiceof displayresolutionchipsets:DLPP icotechnologyoffersa widerangeof displaychipsetsrangingfromsmallresolutio n nHD(640 360),WVGA(854 480)to HD resolution WXGA(1280 800),HD (1280 720)and Full HD (1920 1080) providesthesystemdesignerwith flexibilityin designingand differentiatingproductsacrossbrightness, size,resolution,batteryrequirementsand cost levels.

9 Highcontrast: Dependingon the opticaldesign,DLPP icotechnologycan enablea high contrastratio,whichcreatesdeepblacksand improvesperceivedbrightnessand imagequality. Highspeed:EachDMDmicromirrorcan flip thousandsof timesper second,enablingfast colorrefreshratesand high framerates(120Hz or higherin selectcases).In addition,low displaylatencymakesDLPP icotechnologya greatfit for gaming.
