Mounting systems can attach electronic devices to a wall such as a wall of a television or a wall of a building. Electronic devices can generate a substantial amount of heat that can be trapped by mounting systems. The mount ventilation systems described herein can allow cool air to flow around electronic devices.

The present invention provides a method for manufacturing a highly reliable display device at a low cost with high yield. According to the present invention, a step due to an opening in a contact is covered with an insulating layer to reduce the step, and is processed into a gentle shape. A wiring or the like is formed to be in contact with the insulating layer and thus the coverage of the wiring or the like is enhanced. In addition, deterioration of a light-emitting element due to contaminants such as water can be prevented by sealing a layer including an organic material that has water permeability in a display device with a sealing material. Since the sealing material is formed in a portion of a driver circuit region in the display device, the frame margin of the display device can be narrowed.

Systems, methods, and media for projecting light to indicate a device status are provided. In accordance with some implementations of the disclosed subject matter, systems for projecting light to indicate a device status are provided, the systems comprising: a hardware processor that: determines a light status; determines whether to turn a light source on; selects a light format corresponding to the light status; projects light of a light source according to the light format; and determines whether to turn the light source off.

An object is to provide a technique that enables making an adjustment from a direction where a video display surface is located, in order to provide inconspicuous seams between one of video display devices and other adjacent video display devices even when there are no workable spaces behind the video display devices. A multi-display system includes a plurality of LED display tiles, a position adjusting mechanism, and a pull-out mechanism. The position adjusting mechanism includes a lock mechanism that switches between a locking state and an unlocking state. When the lock mechanism is in the locking state, each of the LED display tiles is fastened in a retraction position. When the lock mechanism is in the unlocking state, each of the LED display tiles is movable between the retraction position and a pull-out position by the pull-out mechanism while being floated and supported via an elastic support portion.

A signal source for electromagnetic interference test of display devices, comprising: a housing capable of attenuating an electromagnetic signal; a parameter receiving module located within the housing and configured to receive related parameters of a signal required for testing a display device; a signal generating module located within the housing and configured to generate a signal required for testing the display device in accordance with the parameters received by the parameter receiving module; and an output interface located on the housing and configured to output the signal generated by the signal generating module. Adopting this signal source to perform EMI test on display devices can eliminate the influence of the signal source, thus reduce the complexity of the test, and make the test become simple and efficient.

An image display device including: an image formation device; and an optical system that brings an image from the image formation device to an eyeball of an observer. 0 (degrees).sub.2<.sub.125 is satisfied where an image-formation-device first strike point is where an extended line of an optical axis of the optical system intersects with an image exit surface of the image formation device, a first normal line is normal to the image exit surface of the image formation device passing through the first strike point, an image-formation-device second strike point is where an extended line of a pupil center line of the eyeball of the observer intersects with the image exit surface of the image formation device, a second normal line is normal to the image exit surface of the image formation device passing through the second strike point.

There is provided an eyeglasses-type wearable terminal that causes a user to more reliably recognize the position of a predetermined object, which includes an image capturing unit that captures the periphery of the user. The eyeglasses-type wearable terminal also includes a determiner that determines whether a predetermined target object is included in a video acquired by image capturing using the image capturing unit. The eyeglasses-type wearable terminal further includes a display unit that displays the position of the predetermined target object in a case in which the determiner determines that the predetermined target object is included.
