Close to Hawkeye 200 ▪ Focus on MBI5353

In ISE 2017, the main theme of Macroblock is Hawkeye 200 *1. Hawkeye 200 uses MBI5353 which has four advantages:

Advantage 1: superior image quality

The display with MBI5353 can not only solve seven challenges*2, but also keep high contrast without losing detail at low grayscale levels.

Advantage 2: intelligent power saving

MBI5353 has intelligent power saving function that is designed for 24/7 operation applications, such as control room and retail. When there is no display of a block controlled by an MBI5353, this MBI5353 will automatically enter power saving mode. Based on experimental data, if the two displays are showing black, the one which enters intelligent power saving mode could reduce power consumption by 40%. 

Or in the application like a control room, as the image (Tram map of Amsterdam) shown below, the display which uses intelligent power saving can decrease power consumption by around 20%.

Advantage 3: adjust brightness without losing grayscale and keeping white balance

As for the rental application, displays need to adjust brightness according to the ambient light. Compared to the traditional way of sacrificing grayscale to adjust brightness, the brightness adjustment module*3 of MBI5353 can maintain grayscale and keep white balance. The user interface is quite friendly and users just need to drag the bar (circled in the red) to select the proper brightness level.

Advantage 4: simple routing on PCB layouts

One MBI5353 can drive same pixels as three MBI5153, and it helps to facilitate PCB layout and decrease total cost.
