Abstract

The invention provides a display and a desktop computer. The display comprises a computer host which is electrically connected with and transmits a power signal. The display comprises a backlight source and a driving circuit board electrically connected with the backlight source. The driving circuit board comprises a PWM (Pulse Width Modulation) driving chip and at least one serial port electrically connected with the PWM driving chip, the PWM driving chip is electrically connected with the computer host through the serial port, and the backlight source is turned off when the PWM driving chipdetects that the serial port has a power supply signal. Therefore, energy and cost can be effectively saved, and unnecessary energy waste can be avoided.

Description

technical field [0001] The present application relates to the technical field of liquid crystal display, in particular to a display and a desktop computer. Background technique [0002] Desktop computers are widely used in office places and entertainment places because of their stable working performance and diverse monitor matching. Due to various reasons, people often neglect to turn off the monitor when shutting down the host, so that the backlight of the monitor is always on, thus causing a waste of resources. As for the backlight of Liquid Crystal Display (LCD), Light Emitting Diode (LED) is widely used due to its advantages of saturated color, low power consumption, long life, short, thin, and green. Applied in the field of display. Due to the continuous improvement of display brightness, this waste is increasing day by day. If when people turn off the host, the backlight of the display can be turned off synchronously with the signal, which can save the loss caused ...
