Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1 to 6, the utility model provides a long-distance double-screen interactive entertainment information processing system, which comprises a host screen 1 and an interactive screen 2; a main processor 3 is arranged in the host screen 1, and a display unit 4 and a touch unit 5 are arranged in the host screen 1 and the interactive screen 2; the main processor 3 is configured to obtain a touch signal of the touch unit 5 of the host screen 1 or the interactive screen 2, so as to control the display units 4 of the host screen 1 and the interactive screen 2 to display synchronously.
The main processor 3 is realized by using an ARM system architecture main chip, and certainly, the present invention is not limited to using an ARM system architecture main chip, and can also be realized by using a main chip of another system, as long as the main chip can process touch signals, video signals, audio signals and the like of a display screen to realize a touch display function, which should be understood as a simple deformation or transformation of the present invention, and falls into the protection scope of the present invention.
