As shown in Fig. 1, the display device 100 includes at least the display panel i 10 and the light source 12A, and other necessary internal components in the display device 100 are not shown in Fig. 1 for the sake of simplicity. The display device 100 is, for example, a reflective liquid crystal silicon (LCoS) projector, but is not limited thereto. The display panel 110 is, for example, a reflective LCoS panel or a thin-film-transistor liquid crystal display (TFT-LCD) panel, but is not limited thereto. The display panel 110 is used to display an image. The light source 120 includes, for example, a light emitting diode (LED), but is not limited thereto. 7 200939178 TW 24927twf.doc/p LED, used as a light source for the display of money, because it can reduce the characteristics of heat i escape, reduce volume and increase life. First Embodiment Referring now to Figure 2, there is shown the timing of the power-on sequence for the display panel and the light source used in the display transposition according to the present invention. e Reference is now made to Figure 2. The first light turns on the low voltage power supply VDD and applies it to the display panel. Next, the low voltage power supply VDD is applied to the electronic circuitry inside the display, such as the gate driver, the source driver, and the low voltage power supply VDD is typically less than 2V. The Japanese version is used to set the display panel. Instructions such as fetch instructions, LCOS write instructions, or LC〇Sff write instructions, but not limited to this. In addition, the command settings can be programmed for different display devices. In this embodiment, power consumption can be saved because it operates under a low voltage power supply. Thereafter, the discharge of the panel is performed after the application of the high voltage power supply VDDA. © Sulfur discharge is to release the residual charge accumulated in the display panel to extend the life of the display panel. These accumulated __ charges may come from an unexpected or abnormal shutdown of the display device. Next, turn on the light source to illuminate the display panel. In this embodiment, the panel is discharged before the light source is turned on, so that the defective image caused by the panel discharge of the display panel is not seen by the user. Second Embodiment 8 rW 24927twf.doc/p 200939178 Figure 3 is a timing chart showing the shutdown sequence for a display panel and a light source applied in a display bud in accordance with a second embodiment of the present invention. , '' Sense First, when the light source is turned off, the user will not see the bad image caused by the discharge of the subsequent panel on the display surface. Then, the display panel is discharged to remove the charge accumulated on the display panel during playback of the display panel. Then, stop supplying the high voltage power supply VDda to the display panel. ' ❺

Instructions include, for example, a sister, an order, an LCoS writer command, or an LCgS read/write command, but not in the second limit. The command settings can then be programmed for different display devices. In the present embodiment, since the operation is performed under a low voltage power supply, power consumption can be saved, and then the low voltage power supply to the display panel is stopped. In the third embodiment, in the third embodiment, the order of the devices (4) is sequentially performed, and the sequence and the sequence are closed. Now, please refer again to the second embodiment of the present invention. Please refer to Figure 2 now. First, turn on the low voltage power supply vdd to apply to the display panel. Next, the low voltage power supply VDD is applied to the display device internal circuit electronic circuit, such as a gate driver, a source driver, and the like. The low voltage supply VDD is typically less than 2v. It is used to set the display panel. Instructions include, for example, LC〇s read 2 commands, LCoS write instructions, or LC〇s read and write instructions, but not limited to this. The command settings can then be programmed for different display devices. In the example of this implementation 9 200939178 TW 24927twf.doc/p, power consumption can be saved because it operates under a low voltage power supply. Next, a high voltage power supply VDDA is applied to the display panel, and the high voltage power source VDDA is used to operate the liquid crystal material of the display panel. The power supply VDDA is used to shift the liquid crystal molecules. ]Come. Q After the application of the high voltage power supply VDD A, the discharge of the panel is performed. The panel discharge is to release the residual charge accumulated in the display panel to extend the life of the display panel. These accumulated residual charges may result from an unexpected or abnormal shutdown of the display device. Next, turn on the light source to illuminate the display panel. In this embodiment, the panel is discharged before the light source is turned on, so that the defective image caused by the panel discharge of the display panel is not seen by the user. Next, please refer to Figure 3. The light source is turned off, so that the user does not go to the defective image caused by the subsequent panel discharge of the display panel. Next, the display panel is discharged to remove the charge accumulated on the display panel during playback. Then, stop supplying high voltage power #VDDA to the display, board. The command settings are used to set the display panel. Instructions include, for example, LCoS item fetch instructions, LCoS write instructions, or [CoS read/write instructions, but not here. The command settings can then be programmed for different display devices. In the present embodiment, power consumption can be saved because it operates under a low voltage power supply. Thereafter, the low voltage power supply VDD supplied to the display panel is stopped. In an embodiment of the present invention, the life cycle of the display device is extended by panel discharge to remove residual charge accumulated during display operation or due to accidental or abnormal shutdown of the display device. Furthermore, because the panel discharge is performed after the light source is turned on, or when the light source is turned off, the panel is discharged after the light source is turned on, the better display performance can be obtained. Further, since the command setting is performed under a low voltage power supply, power loss can be saved.
