How to choose the right retractable monitor?

A retractable LCD monitor for use in aircraft and the like is supplied with power from a power supply that is secured in a fixed off-monitor location on the monitor's housing. The power supply also provides power for a motor assembly that controls a pivoting of the monitor between open and retracted positions. This configuration allows for a compact monitor assembly that can be stowed screen up within a restricted space housing, thus protecting the display from damage by passengers and presenting a pleasing appearance, while still pivoting the monitor by more than 90° to its open position. The motor that is used to pivot the monitor to the open position remains coupled to the monitor pivot mechanism during the retraction cycle, providing a back-emf that resists a spring force used to retract the monitor, and thereby cushion its retraction.

A game machine has a display part connected so as to freely enable storage within a seat on which a player sits. The game machine has a display part for showing game images generated according to a game program and player input, an input reception part for receiving input from the player, a control part for executing the game program according to predetermined external input, including input from the input reception part, a seat part for enabling the player to sit, a storage part for storing the display part formed in the seat part, and a connection rod for connecting the display part to the storage part such as to freely enable storage thereof, of which one end is fixed to the seat part and the other end is connected to the display part.

Arthur Holm is launching its first 24-in 4K motorized retractable monitor during ISE 2018, held next month in Amsterdam.

The DB2 has 20° of adjustable inclination, the housing is made from solid aluminium and the operation button is placed on the top of the screen. The monitor provides a 2mm. double-sided anti-reflective black edged glass.

The motorized retractable monitor with fixed tilt is configurable by way of a secondary LCD 2.2-in display, and by remote control, being able to be configurable and operational without having to remove the monitor from the furniture. When the display is connected to the AH ERT interface, the intuitive addressing system facilitates the address configuration easier due to a single accessible push button.

The unit provides embedded speed and protection pre-sets to restore factory values and an auto-check diagnostic and internal protection functions as well as an auto calibration mode for mechanical speeds and safety parameters .It is firmware upgradeable through a USB port. A safety system detects obstructions (in this eventuality the unit stops). The adjustable mechanical parameters are operational via AHnet or ISD for calibration and mechanical adjustments.

Adjustable parameters of brightness, contrast and backlight are available via RS- 422. An auto calibration mode is available for mechanical speeds and safety parameters.

So, your screen, cheap or expensive, if it is non-tensioned (cheap ones aren't) will likely have or develop waves.

All of this matters because of throw distance. Think about what is going on with a short throw or ultra short throw projector. These projectors throw an image at a very sharp projection angle. This creates a requirement for an absolutely flat screen surface. Any waves or bends to the screen cause severe distortion. Especially towards the edges and the top of the screen.

The solution to this problem is adding more distance between the projector and the screen. The further away the projector is from a wavy screen the less impact the waves on the screen will have on the projected image.

So, yes, you can use short or ultra short throw, but you can't use an inexpensive roll-up screen. In fact, you may need a several thousand dollar screen to accommodate a short throw solution.

Of course, you can always opt for using a wall or a fixed-frame screen to save money. But, if you absolutely have to use a retractable monitor for room design reasons and don't have the budget for a good tensioned model, you will want to place the projector as far from the screen as possible. In that case, it may make sense to go with a more affordable roll-up screen and put the savings into paying an installer to mount a more conventional projector at the back of the room where minor waves and ripples in the screen surface won't be an issue. Just make sure that the projector you select has the appropriate lens to handle a high shelf installation if that's what you've got in mind. Many projectors require a projector mounted near the ceiling to be inverted as they would for a ceiling mount.
