Thereby, when the current value is lower than the current threshold value but sufficient to cause the backlight unit 1 to emit light at the low brightness setting value, the control unit 7 automatically causes the backlight unit 1 to emit light at a lower brightness to make the display The 100 also operates normally in a low power mode. Furthermore, when the current value is lower than the current threshold and is not enough to light the backlight unit 1, but it is sufficient to make the prompt lamp 6 emit light, the control unit 7 automatically causes the prompt lamp 6 to output the prompt signal to Prompt the user that the current value is too low.
在本實施例中，該顯示器100還包含一能接收市電供電的電源連接埠3，該OSD提示訊息的內容例如是提示使用者將該顯示器100接上市電。In this embodiment, the display 100 further includes a power supply port 3 capable of receiving mains power supply.
