Patent number: 11921379Abstract: The disclosure relates to a switching process for switching in an autostereoscopic display device from a first view mode to a second view mode, wherein the autostereoscopic display device comprises a display panel, a lenticular device and means for applying a voltage, the process comprising the application of a switching voltage across both switching electrodes of the lenticular device wherein a ramp voltage is applied that increases during a ramp period of at least 0.50 second from a starting voltage at which the lenticular device is in its, first view mode to a final voltage at which the lenticular device is in its second view mode, wherein during at least 0.40 second of the ramp period, the ramp voltage is at an intermediate voltage that is in the range of 5-60% of the minimal voltage; and the final voltage is equal to or higher than minimal voltage.Type: GrantFiled: December 27, 2019Date of Patent: March 5, 2024Assignee: ZHANGJIAGANG KANGDE XIN OPTRONICS MATERIAL CO., LTD.Inventors: Patrick Godefridus Jacobus Maria Peeters, Hubertus Petrus Cornelis Vankuringen, Ivar Jacco Boerefijn, Andrii Ivanovych Rudavskyi, Pieter Wilhelmus Theodorus De Jong
