Are there thermal management issues with sunlight readable LCD’s?

Yes -any high brightness backlight system will consume a significant amount of power, thereby increasing the LCD temperature. The brighter the backlight, the greater the thermal issue. As well, if the LCD is used under direct sunlight additional heat will be generated as a result of sunlight exposure. Temperature issues have been handled through proper thermal management design incorporating passive and active cooling methods. This is extremely important in maintaining overall reliability and long-term operation.
