A light diffuser (light guidebook plate, LGP) is then utilized to distribute The sunshine evenly over the complete Exhibit, in the same way to edge-lit CCFL Liquid crystal display backlights. The diffuser is built away from possibly PMMA plastic or Exclusive glass, PMMA is utilised typically as it is rugged, when Particular glass is utilised once the thickness of the LCD is of Major issue, because it will not grow as much when heated or exposed to moisture, which lets LCDs being just 5mm thick.
