Lighthouse Technologies Limited (Lighthouse), a LED video display solutions specialist has joined forces with Macroblock, an expert in LED Driver IC to launch the new Quantum q fine pitch LED Screen Series (1.5mm, 1.8mm & 2.5mm pixel pitch) using the Macroblock’s 48-Ch LED Driver IC MBI5353 to deliver the unprecedented LED fine pitch display screen at ISE 2018.

ISE 2018, the world’s largest AV system integration show kicks off today. Macroblock is to showcase its latest LED driver IC product, MBI5359—a high-integration, 48-Channel LED diver IC—suitable for ultra-fine pitch, mini-LED, and micro-LED display solutions.

The Electronic & Optoelectronic System Research Lab (EOSRL) under the Industrial Technology Research Institute (ITRI) is co-developing ultra fine-pitch Micro LED displays with PlayNitride, LED Driver IC expert Macroblock, and PCB maker Unimicron Techology, sources from the industry have revealed.

Macroblock fought a several price war against its rivals in China in 2017, so its product gross margin significantly dropped. The firm's gross margin in 2Q17 fell to 22.68%, far below 32.81%, the average gross margin in 2016.

Organized at the Langham, Shenzhen, on 19th July, Macroblock LED Display Conference 2017, gathering makers of displays and LED light sources worldwide, ended on a high note as it always did for the past 12 years. At this high-profile annual event, Macroblock’s chairman Dr. Li Chang Yang stated that display technology has been more widely used for various applications in different ways, such as displays in retail spaces, theaters, restaurants with immersive AR technology, and interactive applications.

The LED industry had quite a peaceful time in 1H17. Apart from a few M&As, the most-discussed technology would be Micro LED. Lots of high-tech giants worldwide have already started a series of R&D and the number of participants is getting bigger. The supply chain of Micro LED, although of limited mature technologies, is slowly shaping up. Here, LEDinside lists out major events and milestones made on the path of developing Micro LED in the first half of 2017.

Taiwanese IC driver manufacturer Macroblock has successfully developed LED drivers for small pitch displays, and is eyeing driver solutions for an innovative display technology next year, reported China Post.

The exhibition of LED China 2015 in Shanghai brought a perfect ending right before Chinese Mid Autumn Festival. High definition LED displays are everywhere at the show. Exhibitors demonstrated wide applications of high definition LED displays such as interactive LED screens, video walls of control rooms, alternative LED displays to replace LCD or projection screens for meeting rooms and theaters.

Smart lighting remains a popular topic at Guangzhou International Lighting Exhibition 2015. Macroblock targets the lighting applications for public buildings instead of home lighting with the theme “Dimming Art”, bringing many eyeballs during the exhibition.

With the microelectronic techniques and improvement on LED displays, fine pitch LED displays become a more popular solution for replacing indoor displays, such as commercial digital signage in the mall, meeting room, ballroom, TV studio, broadcast room, central control room, and even consumer TV. However, six challenges of fine pitch LED displays still haunt display manufacturers including lower ghosting, dim line at first scan line, uneven brightness, color shift, gradient dim line and cross effect caused by LED failure. These phenomena are obvious when displaying images with more grayscales at low brightness condition.

Macroblock anticipates LED lighting demands to grow, especially in the residential replacement lighting sector, said Chairman LC Yang at the company’s latest investor conference held on May 14, 2014. The company reported revenue of NT $457 million (US $15.1 million) for the first quarter of fiscal 2014. 

Walking along the aisles close to the prototype lighting section at Lighting Japan 2014 at Tokyo Big Sight on Jan. 17, one could not miss the heavily perfumed smells of roses and stock that drifted out from Taiwanese LED manufacturer Macroblock’s booth.

In the second quarter of next year the FIFA World Cup Brazil will feature top grade LED displays in 14 playing venues. With LED display panel driver IC demand starting to emerge, Macroblock chairman Dr. Li-Chang Yang expressed that the company has been receiving an influx of customer orders and the increased output volume has become one of the divers for operation in the second half of the year.

The widespread use of LED display allows advertisers to apply more interactive campaigns with audiences, and the QR code is proven to be an effective way for marketing campaigns on LED displays or LED billboards. However, the popular use of QR code on LED display brings a higher threshold in LED display technology. Critical Limitations of QR Code Scan-ability on LED Display The errors below are common in LED display applications to affect QR code scan-ability. 1.  Positioning Failure in Position Detection Patterns Position detection p...

FPD equipment maker Mirle Automation and LED driver IC designer Macroblock had jointly developed an LED display control system—— Mirle 503. Mirle noted the Mirle 503 had a built-in Macroblock MBI5042 16-channel constant current LED driver with 16-bit PWM (pulse width modulation) control. With the MBI5042, all output channels could be built with 16-bit color depth (65,536 gray scales).

China 60th National Day has just come to a spectacular end. The Tiananmen Square in Beijing was beautified by a lot of LED displays with abundant color and uniform brightness expressing the congratulations to the National Birthday. Some of these LED displays were provided by Beijing Leyard Co. and GULX Tech Co. Macroblock also shines in the ceremony with constant current LED drivers adopted in these LED displays.

Macroblock adopts the leading clock reverse engine in the newly launched 3-channel constant current LED driver, MBI6020, to assure the transmission reliability for LED architectural lighting applications.

Spurred by an influx of orders for the 2010 World Expo Shanghai, LED maker Macroblock’s revenues surged 30% MoM to $4.26 million in August; the growth momentum is expected to extend through September. Macroblock’s third quarter revenues is expected to reach $12 million, a QoQ growth of 34%, which is far higher than the previous estimate of 10~15% growth released at the investor’s conference.

Macroblock, a Taiwan-based manufacturer of LED driver, has released its half-year results of 2009, assessed the business environment, and outlined the business strategy at the investor conference on August 05, 2009. In 2009 half-year financial report, Macroblock reached revenue of NTD553 millions, decreased by 12.4% compared to that of the same period of last year. The consolidated gross profit margin reached 42.8%. The net income was NTD69.8 millions and the earnings after income tax was NTD2.28 per share.

Macroblock introduces a step-down, non-isolated, and high efficiency AC - DC controller, MBI6901, that can deliver constant current to light up high brightness LED and stabilize the LED lighting system. The MBI6901 is able to drive external MOSFET current up to 3A for T-8 CFL replacement, general illumination and power supply for light panel. The MBI6901 accepts universal AC input from 80VAC to 265VAC and regulates the accuracy of preset output current within ±5% by switching the external MOSFET.

LEDinside has recently visited Dr. Li-Chang Yang, Chairman of Taiwan’s LED  IC manufacturer Macroblock Tech, to get some knowledge about the current situation on the global LED display (LED advertising screen) market, and the future developing direction of the company.  

Macroblock launches a new 16-bit PWM LED driver with 8-bit digital dot correction, MBI5040. To provide uniformed LED brightness and accurate LED color for high-end LED display panels, “matched LEDs” are insufficient, and dot correction of each LED pixel becomes necessary. However, it is costly and complex to process dot correction through controllers for the increasing loading of the controllers and the limited control of LED pixels.

Macroblock announced its newly-developed 8-channel and 4-channel constant current LED drivers –MBI1828 and MBI1824, for the application of LCD monitor and high brightness LEDs. Since LED contains no mercury and provides highly directional light source, it is suitable for backlighting applications to provide high brightness. By high voltage process technology, MBI1828 and MBI1824 are designed to light up cascaded LEDs in single channel with high luminance.
