Polaris PowerLED Technologies, LLC has filed another round in its LED display adjustment campaign, hitting Hisense (8:20-cv-00123), LG Electronics (LGE) (8:20-cv-00125), and TCL (8:20-cv-00127) in the Central District of California, where an earlier case against VIZIO is set for trial in September 2020. The asserted patents generally relate to adjusting an LED display backlight, with the defendants accused of infringement through the provision of televisions with certain LED backlight adjustment features (e.g., local dimming, black frame insertion, and scanning backlight features).
