From time to time it is unnecessary to turn on the display attached to the SPC all the day. The Display page provides several frequently used functions such as turning off the LCD and backlight to elongate the display repair period, adjusting brightness or contrast. For example, if user wants the backlight turn-off setting function, he can press "setting" button. Then the backlight page of Display Properties of Control Panel will appear on the screen. Besides, user can click the "Off Now" button to turn off the backlight of the display panel immediately without waiting. Once the backlight was turned off, there were three inputs to turn it on: (1) mouse; (2) keyboard; (3) touch-screen; user can use any one of them to turn on the display. The lower “Brightness” and “Contrast” blocks have scroll bars by which users can tune brightness level of TFT LCD or the contrast level of passive matrix LCD.
