Abstract: A video display system for a meeting includes a video information terminal device typified by a liquid crystal projector, a video display unit typified by a whiteboard, a server which stores information and a user terminal (mobile terminal) held by a member of the meeting. A host of the meeting transmits information regarding the time of the meeting, members, and contents thereof to the server. A reservation list and a participant list are displayed and updated depending on an attendance/nonattendance answer from a member. A diagram or letters written on the whiteboard during the meeting are captured by the video information terminal device, inverted in brightness, stored in a memory, and displayed as a video image. At the end of the meeting, video data is stored as a file. When the meeting is resumed, the stored file is reproduced, developed in the memory, and displayed as a video image.

Abstract: A liquid crystal projector comprises an equipment body containing projection device and cooling device and including an air intake port and an air exhaust port, a case for housing the equipment body, and a sliding device for sliding the case so as to take a first state in which the equipment body is pulled out of the case and a second state in which the equipment body is housed in the case. The air intake port and the air exhaust port are closed at the first state and are opened outside at the second state.

Abstract: A large thin display unit has a chassis structure with a first horizontally or vertically disposed enclosure, a second vertically extending enclosure mounted to the upper side of the first enclosure, and a third vertically extending enclosure mounted above the first enclosure behind the second enclosure. The second enclosure has an opening that opens toward a front of the unit and has a margin along the perimeter of the opening. The thin display section is fixed to the margin in a vertical position. Further, an air route is formed between the third enclosure and a planar portion of the second enclosure, and an air route is formed between the thin display section and the planar portion of the second enclosure. Also, a wiring space is formed between the thin display section and the planar portion of the second enclosure. Preferably, the thin display section is a large liquid-crystal display provided with a plurality of backlights.
