20150065015 | RUBBING DEVICE AND RUBBING METHOD - The present invention relates to a rubbing device and a rubbing method. The rubbing device includes: a substrate carrier, an aligning roller having a surface that is rubbing fabric, a driving mechanism that drives the substrate carrier and the substrate that is to be subjected to alignment treatment carried thereby to undergo a translational movement, and an elevation arm. The lower surface of the aligning roller is made suitable to contact and rub the upper surface of the substrate that is to be subjected to alignment treatment and side edges of the upper surface of the substrate that is to be subjected to alignment treatment are made suitable to scrape the lower surface of the aligning roller. The substrate carrier is provided in a top thereof with channels corresponding to two opposite side edges of the substrate that is to be subjected to alignment treatment in the translational movement direction. The channels are arranged to be suitable to have the two side edges of the substrate that is to be subjected to alignment treatment respectively suspending in the channels. The present invention also provides a rubbing method. The rubbing device and the rubbing method of the present invention use a substrate that is to be subjected to alignment treatment to scrape PI chips from the aligning roller into channels so as to prevent the PI chips from moving with the aligning roller to spread over an AA zone of the substrate that is to be subjected to alignment treatment, thereby improving the defects of bright spots and mura generated in a rubbing process. | 03-05-2015 |
20120105794 | LIQUID CRYSTAL EJECTOR, EJECTION DEVICE, AND LIQUID CRYSTAL EJECTION METHOD - The present invention relates to a liquid crystal ejector, an ejection device, and a liquid crystal ejection method. The liquid crystal ejector includes a liquid crystal container, a nozzle, and a driver. A liquid crystal contained in the liquid crystal container is ejected through the nozzle. The driver controls an amount of the liquid crystal ejected from the liquid crystal container. The driver includes an electrical resonator, which pressurizes the liquid crystal contained in the liquid crystal container according an input of electrical signal in order to realize control of the ejection amount of liquid crystal. The present invention also provides an ejection device and a liquid crystal ejection method. An advantage of the present invention is using a liquid crystal ejector that uses an electrical resonator to control the size of ejected droplets so as to eliminate the occurrence of voids in the process of spreading and avoid marking occurring in the surface of a film due to impact-induced damage. | 05-03-2012 |
