Abstract: A support structure for connecting to a back of an LCD screen to support the same includes a base, onto which a data access device is fixedly mounted with a front of the device facing sideward; a supporting arm extended upward from the base to slightly incline forward and having a hollow upper section, two L-shaped brackets respectively having one arm fixedly connected to the back of the LCD screen being rotatably connected at another arm to upper ends of two sidewalls of the hollow upper section; and a box-type power supply unit removably received in the hollow upper section to electrically connect an external power source to the LCD screen. By adjusting an angular position of the two L-shaped brackets relative to the supporting arm, the LCD screen could be set to a desired angle of elevation.
