GLASS SOLUTIONS

Why Protection Glass?

LCD panels are created by sandwiching a special ‘liquid crystal’ substrate between two polarized .  These sheets of glass are very thin and any pressure or force can deform the structure of the panel.  When implementing interactive video walls, it is important to understand that the LCD itself cannot be touched directly without causing damage.

Touching on the LCD top surface creates deformation in it and this is what causes the rainbow coloured ripples around the point of contact as the liquid crystal alignment is disturbed. When the touch is removed the LCD will return to normal, but doing this for extended periods of time, or using excess pressure will eventually damage the LCD.

In order to maximize the life of the Interactive Video Wall and protect it from damage a protective sheet of glass must be applied over the entire surface.

Traditional Video Walls

Traditional interactive video walls use a single large touch frame/sensor and a single sheet of protective glass to cover the entire surface.  This technique has many disadvantages with regard to the overall performance, cost, serviceability and support of the Interactive Video Wall.

The Modular Solution

The ShadowSense Modular is revolutionary as it solves almost all of the problems and complexities involved in the installation, support and maintenance of large Interactive Video Walls.  It reduces overall system costs, improves user experience and allows you to deploy a product that can easily be serviced and reconfigured at will.

Our technology consists of individual sections that can be simply clicked together to create touch screens of various sizes and shapes. Need a larger touch screen, add an expansion kit. Warranty is a snap, swap out a single section and be back up and running. Regardless of size, the entire touch frame can be shipped in a hand carryable box.

Modular Glass Systems

When the MODULAR touch system is combined with a MODULAR glass solution, the result is a gamechanger.  Not only is the touch frame and display fully modular, the glass has the possibility to make the whole solution modular. Our partners provide two different methods by which to work with glass:

  • Optically bonded video wall monitors
  • Mechanically clipped video wall monitors (Glass Retention Bezel)

Optically Bonded Panels

Optically bonded panels combined with the MODULAR touch system offer the best user experience.  Optically bonding refers to a process by which a thin sheet of glass is glued to the front of the display to provide a protective coating from user interaction.

Pros
  • Exceptional user experience with almost no parallax. The user touches the pixel due to the extremely thin glass used in optical bonding
  • Exceptional display clarity, maximizes the performance of the display
  • An almost seamless touch experience. Optically bonded panels offer an almost flat glass experience with minimal seam between panels
  • Can be easily transported to any location. May reduce cost of transportation, shipping and logistics
  • Easy to service as any monitor can be swapped out and replaced in the field
  • Does not require heavy equipment to lift and align during setup
  • Can be moved through elevators, stairs, tight doorways and corridors
Cons
  • Higher cost of aquisition
  • AR or AG glass is not readily available and must be custom ordered
  • Glass is attached permanently to the monitor and cannot be easily removed

Glass Rentention Bezels

The mechanical Glass Retention System is a cost effective, serviceable, and modular solution that allows protective glass (clear, anti-reflective, and anti-glare) to be mounted directly to each display. The glass is attached to the monitor using four precision machined metal bezels that sandwich the glass and the LCD together without compromising the display or blocking the viewable display area.

Pros
  • Lower cost of acquisition
  • In the event of a monitor failure, the glass can be removed, avoiding any issues associated with servicing a bonded display
  • Can be easily transported to any location. Reduces cost of transportation, shipping and logistics
  • Easy to service as any monitor canbe swapped out and replaced in the field
  • Does not require heavy equipment to lift and align during setup
  • Can be moved through elevators, stairs, tight doorways and corridors
Cons
  • Larger seam between video wall panels
  • Users will be able to feel the seam between panels, does not create a completely smooth surface
  • Possible air gap between glass and display that may reduce the clarity and add to the parallax
Modular
Traditional

Serviceability and support are simple – swap out any section, any time, with simple tools.

Typically, custom made and no spare/replacement parts. Failure often means full replacement on special order. Warranty parts cannot be kept on hand.

Comes in modules to fit 46/49/55″ displays. Supports any monitor vendor.

Any video wall display can be used, no restrictions on vendors.

SST Modular system can be reconfigured at any time. Remove sections to reduce the size, add sections to increase.

Cannot be reconfigured to a different size or shape as the glass and touch sensor size cannot be changed.

ShadowSense Modular is shipped as parts that can be configured on site, reducing cost of shipping, handling, and logistics.

Huge sheets of glass required. Very difficult to ship, move, and handle. Can easily be broken or damaged in transportation.

Easily transported through elevators, stairs, tight doorways and corridors regardless of the size of interactive Video Wall being built.

Large glass sheet and touch frame cannot be moved through elevators, stairs, and doorways without difficulty.

Can easily be setup with minimal labour.

Installation can be complex due to the need for lifts, jacks and other equipment to handle the glass.  The glass sheet can easily weigh up to 100kg and be 6 meters long and 2.5 meters in width.
