<p class="MsoNormal" style="text-indent:24.0pt;">
<span style="line-height:1.5;"><span style="line-height:1.5;"><span>Employed as a spacer in liquid crystal displays (LCD), the black microspheres not only control the thickness of the liquid crystal layer but also prevent leakage of light through the microspheres to improve the contrast of the LCD panel.&nbsp; When immersed or dispersed in a medium for the application, the dark color does not fade or leach out of the microspheres. &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;</span></span></span>

<p class="MsoNormal" style="text-indent:24.0pt;">
<span style="font-size:12px;line-height:1.5;"><span style="line-height:1.5;">Current production of the black spacer centers around mainstream sizes of 4.0 and 6.0&nbsp;</span><i>µ</i><i>m</i><span style="line-height:1.5;">.&nbsp; When placing an order of the product of other particle sizes, a lead time should be considered.</span></span>
