ABSTRACT:
A method for managing bulb brightness, which is suitable for use in a displaying apparatus based on lamp, is proposed. The characteristics of the method include switching the lamp to the standard mode with maximum brightness in the displaying state, and switching the lamp to the ECO mode with reduced brightness in the other states. Therefore, this method is more adaptive than the prior art, making the apparatus to be more convenient in use, and optimizing the use of the lamp in presenting higher picture quality, and prolonging the lifetime of lamp.
