In order to obtain steady-going view zones without crosstalk for eye tracking autostereoscpoic displays using dynamic parallax barrier,an autostereoscpoic display screen with RGBW square subpixel arrangement and tilted parallax barrier is proposed.The operation principle and the calculation equations of the display screen are given.The autostereoscpoic display screens based on the proposed and conventional structures are designed and their luminance distributions along the horizontal direction at the optimal view distance are calculated.The results show that the view zones without crosstalk for the proposed autostereoscpoic display screen are obtained at the optimal view distance.
