Ledman was based in 2004 and is likely one of the world’s consultants on LED UHD shows and chip-on-board (COB) know-how.

It is the primary Chinese LED show firm to be listed, and manufactured the ‘ice rings’ that wowed spectators on the opening ceremony of the 2022 Winter Olympics in Beijing. It additionally has the largest share of the LED fine-pitch COB shows market.

Ledman is dedicated to the 8K UHD video business, with a give attention to 8K Micro LED UHD show merchandise primarily based on COB superior know-how. The firm is a linkage provider of a full vary of LED merchandise and answer ecology.

As properly as UHD shows primarily based on COB superior know-how, its product vary consists of the LEDHUB – AIO Interactive Conference/Education LED Display; Ledman LEDPLAY – Household UHD COB Giant Video Wall; and LED lighting and inventive shows.

Here’s a Q&A with the corporate.

What is Ledman’s Super-COB show know-how? 

The mixture of sub-pixel multiplexing know-how and sub-pixel sampling know-how – plus up, down, left and proper subpixel multiplexing – produces 4 digital pixels, theoretically rising the decision by an element of 4.

In phrases of the software program, a particular optimisation algorithm for Super-COB matching the RGBG association is adopted to enhance show product readability, scale back color errors and restore the unique picture. 

Super-COB show know-how permits the addition of a small variety of LED chips to the construction of 2K merchandise, theoretically realising the impact of 4K merchandise, and leading to a major fall within the quantity of LED chips required and the manufacturing prices of Micro LED shows. The Super-COB know-how has been broadly utilized in Ledman’s COB shows. 

Ledman’s pioneering breakthroughs in know-how have been broadly recognised by the business. In June 2021, its Super-COB show know-how received the ISLE Technology Achievement Award. 

What measures has Ledman taken to guard the Super-COB show know-how? 

In July 2020, the Ledman Micro LED Super-COB show know-how was formally launched. The firm introduced the mass manufacturing of the 0.79mm and 0.63mm pitch Micro LED UHD shows, that are primarily based on COB built-in encapsulation know-how and use Super-COB show know-how.

Ledman has greater than 460 granted and pending patents for its Super-COB show know-how in international locations all around the world.

 The firm  has reserved a number of patent applied sciences for pixel association and pixel construction, forming a big patent pool. These applied sciences – that are key to the smaller pixel pitch, larger decision and decrease value of Ledman’s Micro LED UHD show merchandise – play an vital function in fixing the widespread issues of excessive value, mass manufacturing and low yield confronted by Micro LED UHD show merchandise.  

 What is Ledman’s patent structure in LED industrial shows? 

It consists of encapsulation know-how, interactive know-how and show management know-how, with the patent portfolio masking elements resembling product look, show construction, COB encapsulation, pixel association, display management and human-computer interplay. Ledman has patented a number of innovations for the operate of LED convention shows and the appliance of display management. 

Specifically, to deal with the issues that large-sized Micro LED convention shows are past the operator’s contact vary and inconvenient to function, Ledman invented a collection of human-computer interplay applied sciences resembling ‘small touch and large display’.  

How does Ledman see mental property safety? 

The firm’s ethos is that ‘to protect intellectual property is to protect innovation’. Innovation is extraordinarily vital to Ledman’s technological growth, and mental property is a vital intangible asset – the crystallisation of the knowledge of Ledman’s staff.

Ledman has received the China Patent Excellence Award twice, and is a nationwide mental property benefit enterprise and an mental property demonstration enterprise in Guangdong province. The firm has extensively protected its mental property from patents, emblems, copyrights and different views. As an energetic participant within the growth of LED show requirements, Ledman respects the mental property of others and takes care to guard its personal mental property. 

Only when it’s revered by everybody can mental property repeatedly promote the progress of know-how, and the wholesome growth of the LED show business. Companies should respect one another’s mental property in product growth and product gross sales to keep away from infringement, and should collectively promote the event of the home COB show business.
