Title: Kiyoshi Sawada: Innovator in LED Display Technology
Introduction
Kiyoshi Sawada is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of LED display technology, holding three patents that showcase his innovative approach to power consumption and display efficiency.
Latest Patents
Sawada's latest patents include an LED display system and an LED display device. The LED display system aims to reduce power consumption across multiple LED display devices by synchronizing power-saving controls through individual controllers. Each controller is equipped with a control circuit, a signal line, an average brightness value communication unit, and a video signal distribution unit. The control circuit calculates the average brightness value of the pixels in a frame and generates a READY signal. The average brightness value communication unit then outputs this value to the signal line after completing the calculations. Furthermore, the control circuit computes a common brightness correction coefficient based on the average brightness value, allowing for efficient video signal distribution to the LED units.
In addition, his video display device is designed to drive LEDs using light source driving circuits. It detects maximum signal levels for various colors from video signals across multiple screens and calculates amplification factors accordingly. This device operates in a power-saving mode, reducing power consumption while maintaining optimal brightness levels.
