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.
