In order to improve the display of 360° three-dimensional display system based on rotating linear light-emitting diode array, a simulation program is established. The causes of crosstalk are analyzed in detail: design parameters and system error. And their effects on the display is simulated with the results that the generation of crosstalk can be effectively inhibited by the rational optimization of design parameters and controlling the precision of manufacture. Various perspective views can be reproduced in the simulation program, and the effects of perspective crosstalk caused by design flaws and errors can be simulated, and thus the design of the system parameters is optimized.
