Load driving apparatus adapted to drive outdoor display

Abstract

A load driving apparatus adapted to drive an outdoor display is provided. The load driving apparatus includes a weather sensing circuit and a display driver. The weather sensing circuit is configured to sense a weather condition corresponding to an installation place of the outdoor display, and accordingly provides a sensing voltage signal varied along with the weather condition. The display driver is coupled between the weather sensing circuit and the outdoor display, and is configured to drive the outdoor display for displaying in response to the sensing voltage signal. When the weather condition is a cloudy day, the sensing voltage signal is linearly varied within a predetermined voltage range, and then the display brightness of the outdoor display is linearly varied between a maximum brightness and a minimum brightness.
