Advanced Optical Enhancement (AOE)

GDS provides increased contrast ratios thanks to its proprietary AOE technologies....

Read more...




When installing displays in outdoor and high ambient light environments it is important to recognize that brightness is not the only important factor.
G-Bond reduces the reflective loss from all surfaces to less than 1% by optically coupling the internal surfaces and using an index matched, antireflective coated glass. This increases contrast by 3-5 times that of untreated displays, improving text readability and image clarity.

G-Bond removes the air gap between the display and front cover preventing moisture and condensation from forming a common issue with outdoor displays that are subjected to large changes in temperature and humidity.

Our G-Bond process is applied in class 10000 'clean rooms', and is suited to almost every LCD or Plasma display up to 82". 

GDS G-Bond can be provided as a stand alone service where the client supplies the display,  glass or touch screen for bonding together and our production lines allow flexible production quantities as well as rapid prototyping.

GDS G-Bond is a removable process and as such it reduces the cost associated to service maintenance for panel or front glass replacement.

LED Backlight Technology



LED backlight technology can help lower operating costs by offering a more efficient system with power savings and improved performance.
Compared with traditional CCFL solutions, a thermally managed LED backlight system can be designed to achieve longer operating lifetime, better luminance, uniformity control and dynamic backlight dimming.
LED backlights also have the benefit of no low temperature degradation and do not suffer the start up problems associated with CCFL when operated and started at cold temperatures.
As LEDs are solid state devices, they have better resistance to shocks and vibrations.
Light Emitting Diodes comply with the new RoHS directive against hazardous materials.
