Several measures have been taken to alleviate this effect. The first one is through increased pixel count. A WXGA projector has over 1 million pixels while a VGA panel has only 300,000 pixels. Second, reducing the inter-pixel gaps. A third development is the use of <i>mic<\/i><i>r<\/i><i>olen<\/i><i>s arrays <\/i>(<i>MLA<\/i><i>s<\/i>; Figure 19.9). Though developed primarily to boost efficiency, the MLA concentrates light through the pixel aperture thus de-emphasising the sharp pixel edges.  <\/p>\n<blockquote>\n<p align=\"justify\">\u25cf Relatively low contrast: System contrast is difficult as a result of the field of view (FOV) of the TN LCD mode.  <\/p>\n<p align=\"justify\">\u25cf Lifetime: LC alignment layers used in HTPS LVs are organic polyimides which are susceptible to UV and deep blue light photochemical damage, which reduces operation lifetimes. UV filters with a long-wavelength cut-off are helpful but tend to reduce the blue content of the final colour images.<\/p>\n<\/blockquote>\n<p align=\"justify\">\n","protected":false},"excerpt":{"rendered":"<p>Pros and cons of HTPS projectors HTPS projectors present several advantages and disadvantages when compared with the DMD-based projector.
