Macroblock showcases QR codes on LED digital signage

August 1, 2013

To prove QR code scanability on LED displays, Taiwan-based LED display driver technology provider Macroblock held a QR code campaign with LED display customers at this year's InfoComm show in Orlando, Fla., according to a recent company announcement.

According to Macroblock, QR code campaigns are still gaining traction, but some consumers complain that they cannot scan QR codes on LED displays or LED billboards easily or successfully. The company said its aim at InfoComm was to provide a "scannable" QR code solution for LED displays.

"The QR code boom indeed brings a higher threshold in LED display technology," Macroblock General Manager Robert Chen said in the announcement. "LED display buyers usually put the physical structure, such as easy installation and seamlessness, as the first priority; then the overall brightness; and after that, they think of image quality. But more and more advertisers are using QR codes for marketing campaigns and advertisers realize that making QR codes work on LED displays [has] become even more critical."

Chen explained in the announcement that, "if the refresh rate of an LED display is not high enough, the camera of a smartphone may easily capture black stripes on the screen, which makes [the] QR code not easily or successfully scanned. Macroblock's S-PWM LED driver IC series can simultaneously satisfy the image quality needs of high refresh rate, high grayscale and high luminous efficacy."
