Patent number: 8710507Abstract: A method for manufacturing a semiconductor thin film is provided which can form its crystal grains having a uniform direction of crystal growth and being large in size and a manufacturing equipment using the above method, and a method for manufacturing a thin film transistor. In the above method, by applying an energy beam partially intercepted by a light shielding element, melt and re-crystallization occur with a light-shielded region as a starting point. The irradiation of the beam gives energy to the light-shielded region of the silicon thin film so that melt and re-crystallization occur with the light-shielded region as the starting point and so that a local temperature gradient in the light-shielded region is made to be 1200° C./?m or more. In the manufacturing method, a resolution of an optical system used to apply the energy beam is preferably 4 ?m or less.Type: GrantFiled: February 7, 2013Date of Patent: April 29, 2014Assignee: Getner Foundation LLCInventor: Hiroshi Tanabe

Patent number: RE44063Abstract: In a display device equipped with a light source device, a second light-guide member is provided to the back surface of a first light-guide member that has an emitted light control sheet provided to the front surface thereof. The emitted light control sheet is composed of a flat plate portion and protrusions. A first light source mounted to a side surface of the first light-guide member, and a second light source mounted to a side surface of a second light-guide member are switched and turned on. The emitted light control sheet has light-condensing effects when the first light source is on, and has diffusing effects when the second light source is turned on. The angle range of illuminating light can thereby be switched.Type: GrantFiled: May 19, 2011Date of Patent: March 12, 2013Assignee: Getner Foundation LLCInventors: Shin-ichi Uehara, Masao Imai

Patent number: RE44118Abstract: An edge-light type backlight unit reduces the color unevenness on the display screen caused by the arrangement of point-shaped light sources (e.g., LEDs) in a point-shaped light source unit comprising a set of point-shaped light sources aligned. The backlight unit includes at least one point-shaped light source unit having point-shaped light sources arranged in a single direction in a predetermined order, the light sources emitting monochromatic light of different colors. The unit further comprises a first optical filter for limiting or controlling transmission of the monochromatic light emitted from one of the light sources disposed at one end of the light source unit, and a second optical filter for limiting or controlling transmission of the monochromatic light emitted from another of the light sources disposed at the other end thereof. The first and second filters are selectively formed on a first or second light guide plate or a diffusing plate.Type: GrantFiled: September 26, 2011Date of Patent: April 2, 2013Assignee: Getner Foundation LLCInventor: Eitaro Nishigaki
