Tripartite Cooperation between TSLC, KYMC and Rainbow Pigment targets to revolutionize UVLED Flexo Printing Press

The collaboration will provide turnkey opportunity to transition to UVLED Systems.


September 22, 2020—Miaoli, Taiwan—TSLC Corporation (TSLC), a vertically integrated LED manufacturer, announced its cooperation with Kuen Yuh Machinery Engineering Co., Ltd (KYMC) and Rainbow Pigment Co., Ltd. (Rainbow Pigment). The tripartite collaboration integrates the supply chain and provides press users with solutions and resources.  The integration of manufacturers from ultraviolet light emitting diode (UVLED) systems (TSLC), printing equipments (KYMC) and inks (Rainbow Pigment), enable a seamless,  quick and cost effective transition from traditional curing methods into UVLED.


The collaboration of the three parties of different levels in the supply chain is unprecedented in APAC region. In the past, manufacturers explored the UVLED field independently. Information from the users was provided to their vendors in fragments, without the process of centralized integration, resulting in unsuccessful and/or inefficient experience for users. The cost of implementation will also tend to increase due to trial and error approaches.


In August, 2020, TSLC successfully install its SUPT-K0101

UVLED system onto KYMC’s Ultraflex-612 , a 6 color central

impression (CI) flexo printing press. With Rainbow Pigment’s

new product line, Chromoink, the upgraded press was able to

reach printing speeds up to 350 meters per minute when

printing on polyethylene terephthalate (PET) film and coated

paper in CMYK and white. As the environment-friendly ink is

now solvent free, the installation allows for KYMC to eliminate

thermal treatment and active ventilation systems.

                                             “At TSLC, we always value team work. The service that the new                                                      team provides for user is be unprecedented. Customers will no                                                        longer be confused and lost between UVLED, Ink and printer                                                          technologies.” TH Lin, VP of Sales and Marketing of TSLC, commented.



The three parties in this in this cooperation contribute respective

expertise to assist in UVLED adaptation. TSLC, with over 15

years of UVLED experience, designs and manufacturers UVLED

systems for various press printing equipments, digital printers,

coating and films equipments, cosmetics and medical

applications. While most competitors’ lamp provides only

mechanical adoption service, TSLC’s system provides various

lamp-to-printer signal communications to enable safety

interlocks and failure preventions. Rainbow Pigment was founded in 1983 and was dedicated to tailor-made fine colorants manufacturing. In 2002, it created further established a digital printing ink brand: “Chromoink”. Chromoink focuses on inks for UVLED and traditional UV lamp in various press and inkjet sectors.


 “UVLED (solutions) is a fast growing interest in the press market. The cooperation between the 3 parties will give KYMC a unique edge to our marketing strategies. We are now very confident to provide customers with a complete UVLED solution: from press printer, to UVLED system, to suitable ink. We see the customers being the biggest beneficiary in such collaboration as they will have access to LED technology and services.” Adam Chang, Global Sales Director of KYMC, explained.


                                                     “Many of our customers are evaluating the adaptation of                                                                  UVLED technology but were often held back due to limited                                                              knowledge with LED. With our product portfolio, TLSC’s                                                                  UVLED lamp and KYMC’s equipment, we foresee so many                                                              benefits for our customers. This is not doubt a win-win                                                                      situation for us and the customers.” Paul Yeh, Vice President of Rainbow Pigment, further explained.

TSLC Launches its MiniLED Series Targeting Fine-Pitch Display Markets

Modularization of MiniLEDs for Faster Market Adaptation


December 19th, 2018–Chunan, Taiwan–TSLC Corporation, a vertically integrated LED system manufacturer, announced sampling of its tri-color MiniLED series, targeted to provide LED display manufacturers with surface-mounting (SMT) compatible devices. The company will launch its first product in the tri-color multi pixel series, a 16-pixel RGB array component, to reduce total production costs through increased SMT throughput.


TSLC’s 16-pixel tri-color MiniLED array component “4x4RGBminiArray” aims to replace the market mainstream single pixel components through the advantage of reducing production costs. The 4x4RGBminiArray will simplify the SMT process as there are fewer components to handle, thus significantly increasing throughput over 15 times. The commercial markets strive to deliver top quality images resulting in the exponential increase of pixel count per display. By launching the 4x4RGBminiArray, TSLC provides a highly dense RGB pixel count in a single component.  


“By choosing TSLC’s 4x4RGBminiArray, the user will be able to complete the SMT process of an 8K display in the same amount of time as a FHD display,” explained TH Lin, the Vice President of Sales and Marketing Department of TSLC Corporation. “The component is no longer in the sub-millimeter level and will open up options for SMT subcontractors of a wider range of placement precisions.”


As the market continues to strive for finer pixel pitch, the solder pad on the single pixel packages shrinks. For a market available 550 by 550 micrometer (μm) tri-color package, the solder pad size is less than 200μm by 200μm with pad to pad spacing also less than 200um. The smaller the pad size and pitch resulting in yield loss during SMT on a high cost fine pitch PCB is a large factor in higher costs for fine-pitch LED display. However, TSLC’s 16-pixel tri-color MiniLED array component “4x4RGBminiArray” having 0.5mm pixel with 0.78mm pixel pitch provides a better solution through its large solder pad size 320μm by 320μm with minimum pad to pad spacing ~300μm area. Besides the throughput improvement, TSLC’s “4x4RGBminiArray” also improves SMT process yields and quality by greatly increasing the shear force after the LEDs are mounted onto designated circuit board. Because sheer force is directly related to the size of the LED solder pad, TSLC’s “4x4RGBminiArray” has much stronger shear force than currently available products.  


“By launching this product, we overcome two of the most critical technical hurdles, aiming to enable display modules makers to enter the fine-pitch display markets” TH Lin further explained.


Following the “4x4RGBminiArray”, TSLC intents to launch 8x8RGBminiarray with variable pixel pitches of 0.7, 0.8, 0.95mm by partnering with MiniLED display manufactures. Besides the standard products, TSLC will also be opening up options for customization of pixel pitch, pixel count, package aspect ratio and other specifications.

TSLC Launches its High Power UVC Product lines for Sterilization and Aseptic Markets

Optimized UVC LED emitters targeted for high efficiency and power output


November 10th, 2018–Chunan, Taiwan–TSLC Corporation, leading manufacturer of LED components and OEM/ODM service provider, announced sampling of its ultraviolet C (UVC) product lines. TSLC provides high power and ultra high density UVC LEDs ranging from single chip to multiple chip packages, targeting to provide sterilization and aseptic markets with high power options greater than 500mW.


Currently, market available UVC package technologies involve the LED chips protected in a glass or quartz glass protected air cavity. This is the not most efficient optical design. The differences in refractive index between the semiconductor layer, air and optical material (ie glass or quartz glass) causes UV radiation to be trapped within the chip and the cavity. TSLC’s new UVC LED product series uses a high refractive index material, high UVC transmissible, to increase the light extraction by about 35%. TSLC’s UVC series consists of LED packages of variable footprints and power consumption. The product lineup includes single, 4- (four) and 10 (ten)-chip packages.


“The 10-chip package was specifically designed with options for customization.” TH Lin, the Vice President of Sales and Marketing Department of TSLC Corporation, explained, “This is a 3.6 by 10.0 millimeter emitter of which we could put as many as ten UVC chips with minimal chip pitch to enable optimized light density. The package provides a solution for industrial applications where high UVC radiation is needed.” The LEDs’ small footprint and flexibility was another intentional design concept. Mr. Lin further explains, “The emitter was designed to incorporate ten UVC LED chips, but the package allows for customization in chip count from 2-10 chips. This emitter is surface mountable and can be easily modularized to needed beam shape.”


Due to the increasing demand in UVC light sources, TSLC is also providing design and manufacturing services for customers that are looking for customized UVC modules. The company has the ability to customized emitter and/or chip-on-board solutions. TLSC will also provide or assist our customers with assist with electrical, thermal, and optical designs at the module and system levels to enable our customers’ applications..
