Microsemi's industry leading color management technology, developed for digital TV applications and premium notebook platforms, provides OEMs with the industry's most flexible and color-accurate RGB LED backlighting solution. According to Steve McClure, vice president of marketing for Microsemi's Analog Mixed Signal Group, they are extending their 15 years of leadership in backlighting from Microsemi's portfolio of led high bay light, inverter modules, and light sensors into next generation RGB LED technology. With this comprehensive solution, Microsemi simplifies the technology transition from CCFL to LED backlighting by addressing the inherent color accuracy issues associated with generic LED backlights. their system-level approach in addressing the entire color management loop allows them to provide OEMs and LCD panel suppliers with an easy-to-implement economical solution. This approach will fuel an entire family of system-level solutions for the emerging RGB LED display market.
It’s disclosed that Microsemi's advanced LED color management solution is designed to enable notebook users to adjust the white point of the backlight--using a simple graphical user interface --with virtually instantaneous response and an accurate color palate as the Microsemi color loop controller compensates for any changes in color point settings within milliseconds.Microsemi Corporation, with corporate headquarters in Irvine, California, is a leading designer, manufacturer and marketer of high performance analog and mixed-signal integrated circuits and high reliability semiconductors. The company's semiconductors manage and control or regulate power, protect against transient voltage spikes and transmit, receive and amplify signals.
LED architectural lighting applications. It features a high-speed serial interface, which can support data rates up to 25 MHz and offers fully buffered data outputs to ensure the highest data integrity is maintained over distributed, daisy-chained lighting systems. The CAT4109 uses a parallel interface with each channel having a dedicated PWM control, making it ideal for the more conventional LED visual effects applications, such as color-mixing and accent architectural lighting.Both the CAT4103 and led high bay support a wide range of LED constant current drive of up to 175 milliamp (mA) on each channel, with dropout levels down to 0.3 volt (V). This ensures maximum performance in driving long strings of LEDs. With voltage compliance levels of 25 V on each channel, these drivers are capable of supporting RGB pixels with brightness power levels in excess of 10 watts.
