Abstract: An electronic device information read/write mechanism includes an RF tag attached to a metal frame at the upper portion of a liquid crystal display panel packed in a packaging box. The RF tag stores the internal information concerning the liquid crystal display panel. The packaging box is partially opened to expose the RF tag to the outside, and then an external reader/writer is moved close to the RF tag, and therefore the external reader/writer reads or writes the internal information stored in the RF tag without powering on the liquid crystal display panel.

Abstract: A display device includes: a display monitor; a control board which drives the display monitor; a chassis which is provided between the display monitor and the control board. The chassis includes a conductive material, and has a surface on a side of the display monitor. The display device further includes: a wiring line which is provided along the surface of the chassis; and a clamper which fixes the wiring line to the chassis. The clamper includes a clamp section pressing the wiring line, and leg portions fixed to the chassis. The chassis includes a recessed section at a position where the clamper is fixed. The recessed section is indented towards a side of the control board and accommodating the wiring line.

Abstract: A display device includes a display device a display panel (e.g. a blackboard or a whiteboard) juxtaposed in a frame. The rear face of the display device is covered by a cover having a height and a planar part. It is possible to selectively attach a reversible I/O unit and a reversible option slot unit to either the right side end or the left side end in the planar part of the rear face of the display device in such a way that input/output terminals are directed to the exterior of the display device. Additionally, an air outlet and an air inlet are formed in the surface of the option slot unit opposite to the rear face joining the planar part of the rear face of the display, thus securing air ventilation. The display device having user friendliness can be easily manufactured using standardized parts with a low manufacturing cost.

Abstract: Different board-type devices can be selectably attached to a device attachment slot of a display apparatus. A first board-type device has a depth corresponding to the device main body thereof. A first female connector of the first board-type device inserted to the device attachment slot is connected to a first male connector of the apparatus. In a second board-type device having a shape different from the first board-type device, the device main body thereof is connected to a connector via two adaptor boards having a step therebetween. Accordingly, in the second board-type device, even the device main body, which has a smaller depth than the chassis whose depth coincides with that of the first board-type device, and can be selectably attached to the device attachment slot with respect to the first board-type.

Abstract: A display device includes: a display monitor; a control board which drives the display monitor; a chassis which is provided between the display monitor and the control board. The chassis includes a conductive material, and has a surface on a side of the display monitor. The display device further includes: a wiring line which is provided along the surface of the chassis; and a damper which fixes the wiring line to the chassis. The damper includes a clamp section pressing the wiring line, and leg portions fixed to the chassis. The chassis includes a recessed section at a position where the damper is fixed. The recessed section is indented towards a side of the control board and accommodating the wiring line.

Abstract: A display device includes a display section, a frame casing including first and second divided frames, each of the first and second divided frames including first and second holes along a width direction of the frame casing, the first hole being closer to a back surface of the display section than the second hole, the first and second divided frames being attached to the display section by screws passing through the second holes, and a glass plate provided between a front surface of the display section and the frame casing.

Abstract: A frame housing is provided on a peripheral surface of a display unit. The frame housing includes: a plurality of divided frames including a plurality of attachment portions including a through hole used for screw-fastening to a screw hole provided in the peripheral surface of the display unit. The through hole is an oblong hole with a long-axis direction of the oblong hole arranged in a direction along the peripheral surface of the display unit.
