20080266227 | METHOD FOR DRIVING LIQUID CRYSTAL DISPLAY DEVICE, LIQUID CRYSTAL DISPLAY DEVICE, AND ELECTRONIC DEVICE - An object of the present invention is to provide a driving method of a liquid crystal display device for improvement of image quality and a liquid crystal display device in which the driving method is used. One frame period is divided up into an n (n: integer, n≧3) number of periods (hereinafter referred to as subframe periods). Furthermore, a voltage is applied to a liquid crystal so as to correct for a loss in luminance resulting from response speed of the liquid crystal. The voltage for correction is applied during subframe periods other than the first subframe period. | 10-30-2008 |
20080284720 | Liquid crystal display device, electronic device, and driving methods thereof - An object of the present invention is to provide a driving method by which excellent image quality and high video performance can be obtained as well as liquid crystal display devices and electronic devices with excellent image quality and high video performance.

20110030212 | METHOD FOR MANUFACTURING TERMINAL STRUCTURE AND METHOD FOR MANUFACTURING ELECTRONIC DEVICE - To provide a method for forming an opening with high accuracy in an insulating film obtained by curing a prepreg including a reinforcing material in a step of exposing a terminal portion sealed with the insulating film, with the use of a means other than laser beam irradiation. A protrusion is formed using a conductor. An uncured prepreg including a reinforcing material is closely attached to the protrusion and the prepreg is cured, so that an insulating film including the reinforcing material is formed. A portion of a top surface of the insulating film protrudes due to the protrusion. The protruding portion is preferentially removed together with the reinforcing material to form an opening in the insulating film by grinding treatment or the like, so that an opening which exposes the protrusion is formed in the insulating film. | 02-10-2011 |
