Abstract: Large displays and panels are increasingly being manufactured and commercially exploited for both indoor and outdoor screens. In considering that the maximum brightness required of a CRT is typically 70 cd/m2 and that for outdoor screens it is approximately 5,000?cd/m©÷ under direct sunlight (the sun emits approximately 4,000 cd/m2) [3], understandably outdoor large LED displays may experience high power consumption and heating complications. This is further increased when such displays are used under high temperatures during summer afternoons. In this regards, this paper investigates how heat display may be reduced while ensuring luminous efficiency within large displays. , we successfully reached a lower operating voltage at 0.5V and a 20% higher efficiency. Henceforth, in comparison brighter pictures are displayed.
