SiliconCore Technology (SCT) was founded in 1997 in Milpitas, California. The company started its business as a semiconductor intellectual property developer, serving Silicon Valley based semiconductor companies. In early 2000, the company transitioned to a fabless semiconductor company with initial focus on current mode laser diode drivers for the optical storage market. By 2010, through persistent effort, the company established itself as the global market leader in laser diode drivers. Through many years of semiconductor design, SCT has accumulated a vast amount of semiconductor intellectual property, especially relating to current driver design and its system applications. In 2010 the company identified the LED display and lighting markets as an ideal fit to the SCT design expertise. In order to solve the LED display heat and ghosting problems, the SCT engineers invented the common cathode current driver architecture. This patented technology effectively removes the heat and reduces the power consumption of the system. Since 2011, SCT has initiated the development of several generations of common cathode LED driver and LED display panel designs, making this technology commercially available. The company firmly believes that the common cathode LED display is the best large format display technology available today and is commied to the continuing development of LED display products based on this technology. As a technology provider, SCT is not only promoting its LED display system business but also actively licensing its common cathode technology to the LED display industry worldwide. This book provides a general technology introduction of the common cathode technology and an overview of the SCT system technology available today.

Common Anode Technology Common Cathode Technology

!R.G.B same power supply !R.G.B separate power supply

!External voltage drop resistor ◆ No external resistors at R channels Advantages: Disadvantages: !Save external resistor !Need external resistor !Low heat dissipation !High heat dissipation !Longer LED lifetime !LED lifetime reduction !Low Power dissipation !High power dissipation

!Low integration & High EMI

!Low manufacturing quality

!Difficult maintenance

The common anode LED configuration seriously impairs the development of the higher resolution LED display panel market. LED displays based on the common anode solution have difficulty achieving a pixel pitch below 3mm (P3) at reasonable quality. In order to compensate for the smaller pixel to pixel distance, traditional common anode LED display designs have to reduce refresh rate and gray scale resolution, increase power consumption and also generate serious ghost effect. Due to the low integration and high power consumption, external cooling fans may be required, further increasing the power consumption and panel thickness. The common cathode technology from SCT effectively overcomes this industry scalability barrier and establishes a platform for higher resolution LED display technology evolution. LED display panels using the common cathode solution can go down to less than 1mm pixel pitch without any sacrifice in quality. These fine pitch displays have higher refresh rate, higher gray scale and higher integration in cooler, lighter and thinner cabinet, with no requirement for external fans or cooling. Refresh Rate and Gray-scale Optimization

High refresh rate design Lower refresh rate causes horizontal lines

!The traditional common anode design has inherent heat generation which prohibits higher integration. Higher resolution requirements demand more complex PCB designs to accommodate all the components and longer PCB traces which further limit the PCB bandwidth and also result in higher EMI emissions. Lower bandwidth results in lower refresh rate and lower gray scale. One common solution is to sacrifice gray scale level in favor of higher refresh rate.

!The SCT common cathode design approach has inherently lower power consumption which allows higher integration. The SCT highly integrated common cathode LED driver reduces component count, generates less heat and allows the integration of LEDs and all other necessary components on the same PCB. The simpler PCB design also offers higher bandwidth and reduced EMI emissions while higher refresh rate and higher gray scale can be achieved. Ghost Effect Elimination

Ghost effect cause blurred video picture !The ghost effect is caused by accumulated charge in the parasitic capacitance, which causes the LED to continue Without Ghost Elimination emitting light after it is supposed to be turned off. A common solution to this problem is to use a bypass resistor or other extra circuits on the PCB to remove the parasitic capacitance charge and reduce the ghost effect.

!The traditional common anode designs have more difficulty in removing the ghost effect at higher LED display resolutions. The more complex PCB designs and larger parasitic capacitance result in more components and a longer discharge time to reduce the ghost effect, resulting in a lower refresh rate and gray scale performance.

!The SCT common cathode design deploys the SCT proprietary ghost elimination technology which completely discharges the parasitic capacitance. The lower parasitic capacitance, from the shorter PCB traces and simpler PCB design, also helps to minimize the discharge time and increase With SCT Ghost Elimination the refresh rate and gray scale. Technology Cool and Silent Solution

SCT P1.9 module

!The traditional common anode design is low integration and has high power consumption, generating more heat. It may require external cooling fans which increase the overall LED panel thickness and also generate noise.

!The SCT common cathode design consumes less power and generates less heat. No external cooling fans are required. The simple mechanical and thermal designs make this an optimum platform for high resolution LED displays.

P1.9 Implementation Case: China Changzhou New Energy Research Center Lobby 1080P video screen

4K Panel

!The 4K format is the next generation high definition (HD) standard for displaying extremely high quality HD video. The 4K format uses four times the number of pixels (3840 x 2160) over the current 1080p format (1920 x 1080), resulting in the ultimate resolution and image quality. All major TV manufacturers and video providers have either launched products supporting the 4K format or are busy finalizing their 4K product developments, building enough momentum behind this standard to ensure its success and dominance of the high resolution HD market. However, even the latest large LCD TVs cannot fully exploit the quality of the 4K image content due to LCD panel technology limitations in brightness, color contrast and color saturation. These limitations can be overcome with LED display panels, but large pitch LED displays require unreasonably large physical screen sizes to accommodate the full 3840 x 2160 pixels of the 4K format.

!The latest SCT P1.9 4K LED display panel offers the optimum solution for rendering the full detail and quality of the 4K format at the perfect screen size. With a pixel pitch of 1.9mm, the SCT 4K display screen is just 4.1 meters high by 7.3 meters wide (approximately 13’6” high by 23’11” wide), offering the ideal cost effective solution for displaying 4K content with the stunning quality of the SCT LED display technology. The SCT 4K LED display panel redefines the viewing experience and sets a new standard for high resolution image display quality!
