Is it possible to control the brightness or switch on and off the backlight of an Waveshare display via command line or a script?

I'm using the 7 inch version (rev2.1) with a resolution of 1024x600 on a Raspberry Pi 2. The display is connected via HDMI and a usb cable for touch capability.

Thanks for any help.

I reached out to Waveshare directly and received the following information from them:

The official display you can control, the Waveshare you have to do the following hack by wiring the pad in the image below to a GPIO pin on the Pi. You then can control the brightness with PWM signal on that GPIO pin.
