Patent number: 6688576Abstract: A display panel of the display apparatus is encompassed by a front case from the front and by a rear case from the back. The display apparatus includes a first attachment structure capable of attaching/detaching the front case on the front side, and a second attachment structure A formed on the four corners of the rear case for attaching the display apparatus to the wall. The attachment operation for attaching the display apparatus to the wall is performed while the front case is detached. After the completion of attaching the display apparatus on the wall, the front case is attached by way of the first attachment structure to prevent the second attachment structure A from being exposed to the front.Type: GrantFiled: March 26, 2002Date of Patent: February 10, 2004Assignee: Pioneer CorporationInventors: Toshiharu Oishi, Sadao Yokoi, Daisuke Takao, Koichi Kaneko

Publication number: 20020153836Abstract: It is an object of the invention to save space, improve workability and visible appearance when a display apparatus is fixed to a wall. A display panel of the display apparatus is encompassed by a front case from the front and by a rear case from the back. The display apparatus includes a first attachment structure capable of attaching/detaching the front case on the front side, and a second attachment structure A formed on the four corners of the rear case for attaching the display apparatus to the wall. The attachment operation for attaching the display apparatus to the wall is performed while the front case is detached. After the completion of attaching the display apparatus on the wall, the front case is attached by means of the first attachment structure to prevent the second attachment structure A from being exposed to the front.Type: ApplicationFiled: March 26, 2002Publication date: October 24, 2002Applicant: Pioneer Corporation & Shizuoka Pioneer CorporationInventors: Toshiharu Oishi, Sadao Yokoi, Daisuke Takao, Koichi Kaneko
