Consequently, when an external force is applied to one touching position on the counter substrate, the conductive particles electrically connect the sensing electrodes to the electrode layer and the touching signal of the position can be obtained. Due to the integration of the conductive particles into the liquid crystal cell gap, the multi-touch LCD panel has the advantages of slimness and lightness. Moreover, the manufacturing process of the conductive particles is introduced after the conventional counter substrate manufacturing method, and the objective of simple process, low cost and high yields can be achieved.Type: GrantFiled: August 25, 2010Date of Patent: June 12, 2012Assignee: Century Display(ShenZhen)Co.,Ltd.Inventor: De-Jiun Li

Patent number: 8184215Abstract: A polarization modulator for time-multiplexed stereoscopic 3D applications rapidly switches between two polarization states in alternate subframes. The polarization modulator uses two liquid crystal devices arranged in optical series and driven such that the second device compensates a change the first device makes to an input polarization state of incident light during alternate subframes. The compensating liquid crystal devices are characterized in that, if the same voltage is applied to both of them, the second device compensates the change that the first device makes to the input polarization state, regardless of the applied voltage level. If the applied voltage is changed from one level to another and the liquid crystal material in the liquid crystal devices relaxes to the new voltage level, polarization state compensation will take place throughout the duration of the relaxation so that the slow, unpowered transition does not manifest itself as a change in polarization state.Type: GrantFiled: March 28, 2011Date of Patent: May 22, 2012Assignee: LC-TEC Displays ABInventors: Jesper Osterman, Terry J.
