Description of the Invention: [Technical Field of the Invention] The present invention relates to a method for managing brightness of a bulb, and more particularly to a bulb brightness of a display device using a bulb to generate a kneading surface Management method. [Prior Art] There are a large number of display devices which generate a surface according to the light emitted from the bulb, for example, a projector is one of them. The operation of such a display device is usually divided into several states, as shown in Fig. 1. In the state diagram shown in Figure 1, when the display signal is present, the display device will be in the display state 103, displaying the normal face. When the display device is searching for a display signal, it enters a search state 102. When the announcement signal does not exist, the display device enters the no signal state 101. When the user temporarily turns off the screen, the display device enters the video mute state 104. In this type of display device, the bulbs are high-priced consumables, such as the bulbs of the machine, which retail at a price of 20% to 30% of the projector itself. Therefore, there has been a method of reducing the brightness of the bulb in order to extend the life of the bulb. In the practice of the eye, the bulb can be set to the standard mode (stan (jar) or ECO mode, where the standard mode brightness is 100%, and the eco mode brightness is 80%. When set to the eco mode, it can be exchanged for a longer life with a lower brightness. The problem is that the current practice lacks flexibility and cannot automatically switch the lamp mode. When the lamp is set to the standard mode, no matter which one in Figure 1 status,
