GDS Launches 4,000cd/m² High Bright LCD Displays for Full Outdoor Applications

At the ISE show in Amsterdam from 2-4 February 2010, GDS unveiled its new high bright family of products: Sirius.

The excitement and expectations around these brand-new products are very high as they can finally give outdoor communication the ‘wow’ factor the digital out-of-home market has been always looking for. The new high bright products are ideal for digital signage and public information display applications.

“The technology behind these stunning images and this unmatched level of picture detail in full sunlight outdoor environments is all but obvious,” says Andrea Ongaro, chief technology officer of GDS. “Researches, testing and investments around this project have been massive but now GDS can offer to the market very high performances in outdoor environments as well as high reliability and improved ROI. With nearly 15 years of experience, this product range confirms GDS being at the forefront of outdoor display technology.”

The new GDS Ultra High Bright (UHB) technology, incorporated in the new UHB products, is the result of a perfect integration between an LED backlight, a cooling system and G-BOND optical enhancements.

The LED backlight, designed by GDS, makes the display reach 4,000cd/m² by using high-efficiency white power LEDs. The use of LED backlights also allows a power saving of nearly 40% if compared with displays with CCFL backlights.

By using a traditional LED’s dimming, instead of local LEDs’ dimming, GDS reduces the risk of burning effects on the screen and improves the life of the system. The contrast will be as good as a system with local dimming as the monitor will be used in a high-ambient-light environment and not in a dark room. LEDs are also a green alternative to CCFL lamps as they are mercury-free.

The new UHB Line has a Twin-Cooling System™ that keeps the panel as well as LED backlight and electronics at the optimal temperature. This improves the MTBF of the whole display and the efficiency of all internal components. The Twin-Cooling System doesn’t use air conditioning, therefore reducing power consumption and optimising number of components. The Twin-Cooling System prevents the display from reaching the clearing point or from generating moisture in front of the panel and makes the entire system working even in direct sunlight conditions.

All these masterpieces of technology receive great benefits from GDS G-BondTM, that improves contrast of images in very bright environments and strengthens the TFT panel by bonding an antivandal glass of 6mm-8mm thickness. At the same time G-Bond protects the panel from mechanical and thermal stresses coming from cooling air streams that reach the speed of 6m/s to cool a 1m² panel.

“GDS proprietary technologies allow GDS to use different panels to accommodate customer requests.” continues Andrea Ongaro “This flexibility gives the customer a wide range of options of features.”

The new range, initially available in sizes of 65in and 46in, will be shown again at Digital Signage Expo, Las Vegas, US, from 23-25 February 2010 (booth 2425).
