Macroblock, the LED display driver specialist, has released details of its annual conference. In its report on the event, it explained the advantage of a common cathode configuration, which allows the voltage to be independently varied according to the colour, which allows a lower voltage for the Red LEDs, and reducing power consumption.
The company showed three configurations, one with a common anode driver (37W), one with common anode, but with power saving (33.3W) and a third with a common cathode configuration (29.8W).
Macroblock also demostrated the difference between 14 bit SDR content and 16 bit HDR content (using 10 bit content). This content was shown using the firm’s MBI5359 driver. (Macroblock is supplying the drivers for Samsung’s LED cinema displays, so needs to be able to support HDR (Macroblock Wins Samsung Business, Optimistic on microLED)

We reported on the demos that Macroblock showed at Infocomm and ISE of the demonstration miniLED displays developed with PlayNitride. The companies say that the displays can reach 84% of the Rec. 2020 colour gamut (150% of Rec. 709 and more than the 140% that the company says is provided by the Sony Cledis). The firm said at the event that it has reached 99.99% yield (we presume in putting the LEDs onto a substrate – still a long way from a saleable quality level – Man. Ed.) (ISE 2018 Catch Up)
A new product category for the firm is a “set top box” for LED displays that can make it easier to make the most of LED in digital signage both by helping with content playout and by providing sensing including integrated face recognition.
