Abstract: A touch screen data transmission system enabling a single touch screen to communicate with and command a plurality of hosts includes a dividing module, an obtaining module, a determining module, a converting module, and a transmitting module. The dividing module divides the touch screen into a plurality of touch areas which each have own start and end coordinates and each touch area is relevant to one host of the plurality. The obtaining module obtains a coordinate of a touch point and determining module determines the relevant touch area. The converting module converts the coordinate into an area coordinate and the transmitting module transmits the area coordinate to relevant host to open that host for communicating and commanding purposes. A touch screen data transmission method and a split touch device are also provided.

Abstract: A display device includes a front frame, a display module installed in the front frame, and a rear cover connected with the front frame. The front frame includes a plurality of securing rods connected one by one. Each securing rod defines a receiving groove and a plurality of grabs. The display module includes a plurality of limiting plates. The rear cover includes a plurality of latch blocks. The limiting plate is received in the receiving groove. The latch block is inserted into the grab.
