Display Filters

We have various optical filter products to protect your display and improve performance.

– Glass

We provide high quality display glasses with various thickness and surface treatment options such as fine matte anti-glare, multi-layer anti-reflective and conductive ITO coating.

Chemical strengthening and silk screen printing are also available.

  • Plain Float Glass
  • Anti-Reflective Glass
  • Anti-Glare Glass
  • Non-Glare Etched Glass
  • Chemically Tempered Glass
  • Conductive Coated Glass
– Color

Additional colors and tints can be added onto any types of displays by using colored glasses or polycarbonate or tinting layers.

There are various options for tint layer technology of optical filters, it can be partially applied on the display as well.

Anti-Vandal Shields

Rugged filters are available in a variety of thicknesses and sizes for display protection.

With excellent resistance to shock, scratches and chemicals, several surface treatments are available to optimally view the flat panel displays based on specific surface treatments. All finishing treatments are designed for anti-glare, maximum light transmission and durability.

EMI/RFI Shields

EMI/RFI Shields protects the system from Electromagnetic interference (EMI), which causes electromagnetic interference, malfunctions due to noise, and signal quality that cause system degradation in electronic equipment and system operation and it is necessary for applications that provide high electrical properties.

EMI (Electromagnetic Interference) shielding is implemented by using the latest products such as Metal Mesh, etc.

  • Military displays
  • TEMPEST security equipment
  • Aviation Display
  • Marine AUTO Pilot System
  • Medical equipment and MRI rooms
  • Tests and Measurements

Transparent Heaters

Typically, the flat panel displays’ screen response varies with temperature.

Display heaters help to extend the operating temperature of the flat panel displays and backlights by improving LCD, OLED or plasma displays’ performance especially at low operating temperatures. Military Optical Filter Transparent heaters maintain an LCD temperature of 20°C in an ambient temperature of -50°C.

Transparent heaters can be applied on both single and multi-layered panels and if fully laminated, placed inside the lamination to increase durability and safety. Additional layers can be included for shock resistance, EMI shielding, contrast enhancement and anti-glare control.

Transparent heaters are widely used in public information displays, material handling equipment, military ground-based vehicles, naval flight deck equipment, control panels for heavy agricultural and ground movement equipment, periscopes and offshore oil platforms.

Touch Sensors

Touch sensor technology simplifies and enhances the human interface for display systems. From the use of keyboard, switch or button to the development of touch technology, design flexibility is increased for ease of use

  • Resistive
  • Capacitive
  • Infrared (IR)
  • Wave (SAW)
  • Multi-Touch

Privacy Filters

Privacy filters are used for screen data security. Screens can only be seen clearly in front of the filters. The specially designed film shows only a black screen at a viewing angle of more than 30 degrees from the side.

Used for displays that require privacy for viewers, such as ATMs, medical kiosks, inflight entertainment screens, and outdoor privacy screens.

Types of Filter Coatings/Etchings

Antireflective (AR)

Single-Sided (recommended for bonded filters)

Double-Sided (recommended for non-bonded filters)

Antiglare (AG)

Chemically Etched

Mechanically Etched

Easy-Clean (smudge resistant)

Type of Adhesive


Silicone adhesives have been used for commercial and military display joints for more than 30 years. Due to its soft material properties, it has an advantage of easy reworking. Its disadvantages are due to its product properties, the adhesion is not strong and attention must be paid to the adhesion of the edges. For this reason, a thin black tape is used or bond edges are sealed to prevent wear on the edges.


The other adhesive we use is an acrylic formulation. It has a much firmer bonding than silicone, but does not tend to form particulate debris. If a problem occurs during production or usage, reworking is not possible. However, for some designs where it is not practical to use a tape to seal the edges, this may be an option of choice.
