[Embodiment] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings of the embodiments. The same or similar reference numerals are used in the drawings to describe the same or similar parts. First Embodiment Fig. 1 is a view showing a display device in an embodiment of the present invention. As shown in Fig. 1, the display device 100 includes at least the display panel 110 and the light source 120, and other necessary internal components within 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 11 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 1357039 24927twf.doc/p HD-2007-0017-χ^γ LED = used as a light source for display devices because it reduces power loss and heat loss, volume reduction and increased lifetime. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to Figure 2, there is shown a timing diagram of a display device in a display panel and a light-sequential sequence in accordance with a first embodiment of the present invention. Now refer 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 an electronic circuit inside the display device, such as a gate driver, a source driver, or the like. The low voltage supply VDD is typically less than 2V. The command settings are used to set the display panel. The instructions include, for example, an LC〇s read command, an LCoS write command, or an LCoS read/write command, but are not limited to this. The command settings can then 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. 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. The light source is then turned on 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 1357039 HD-2007-0017-TW 24927 twf.doc/p Figure 3 shows the timing of the shutdown sequence for the display panel and the light source in accordance with the second embodiment of the present invention. In the display device, first, the light source is turned off, and the user does not see the bad image caused by the subsequent panel discharge. - In the panel of the panel, the surface of the panel is subtracted (4) and the charge on the display panel is accumulated. _,stop

The VDD VDDA command setting is used to set the display panel. Instructions such as instruction fetch, LCoS write command, or L(10) read/write; ^ LCoS item Next, the command settings can be made for different display devices~ not limited to this. In the example, 'because it operates under low power, it can save power: 2, after the application, the supply is stopped. - The third implementation example f is the third implementation, according to the consumption riding device = Shi: Please refer to Figure 2 and Figure again. 3 to interpret = to reveal ίΠ Figure 2. First, turn on the low-power waste power supply vdd to apply to the display panel. Connected to f 'low voltage Wei VDD is internal electronic circuit, such as the gate 駆 哭 cry, ^, bedding mourning voltage power supply is usually lower than the source driver and so on. Low t slave is used to set the display panel. The instructions include, for example, an LC0S read =^L^OS write command or an Lc〇s read/write command, but are not limited thereto. The Receiver 4 command can be programmed for different display devices. In the present example, HD-2007-0017-TW 24927 twf.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 supply VDDA is used for operation of the liquid crystal material of the display panel. For example, the high voltage power supply VDDA is used to shift the liquid crystal molecules. Thereafter, the discharge of the panel is performed after the application of the high voltage power supply VDD A. 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 cause unexpected or abnormal shutdowns. " 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. As a result, 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 see a bad image caused by subsequent panel discharge of the display panel. Next, 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. The command settings are used to set the display panel. Instructions include, for example, LCoS έ buy orders, LCoS write instructions, or LCoS Ί buy write instructions, but not limited to this. The command settings can then be formatted 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 operation of the display device or due to accidental or abnormal shutdown of the display device. In addition, because at the time of booting, before the light source is turned on, or when the power is turned off, the light source 1357039. HD-2007-0017-TW 24927twf.d〇c/p is discharged for panel discharge, which can be better. Display performance. More cost-effective because the instruction setting is performed under the low-voltage power supply, it can be said that the present invention is disclosed in the above embodiment, but it is not intended to be limited, and any technical field of the technical field has no financial knowledge, and does not leave = ' When you can make a little more - so accurate.
