To solve disadvantages in application of LCD display screen

design a LCD wisdom display and control system. The display and control system uses infrared induction device to make display automatic wake-up

automatic power-off

adjust the angle of the display to achieve the optimal viewing effect by using steering gear. Use face API based on Oxford Project to write program

and the deveice can recognizes the age

gender automaticly according to the collected face image information

and thus the deveice can select display content intelligently. The hardware structure of the whole system and the software flow of the lower computer and upper computer are described. The validity and rationality of the performance of the system are verified by experiments.
