RGB-LED backlight monitor for TFT-LCD (Liquid Crystal Display)
Recently, RGB-LEDs have been in the focus of attention as the backlight for TFT-LCD (liquid crystal display) since LEDs are mercury-free unlike conventional cold cathode fluorescent lamps. Hamamatsu C9303-04 color sensor module has been specifically developed for the power monitor of RGB-LEDs. We welcome requests for custom shapes and RGB gain. Feel free to contact our sales office.
Features
Sensitivity matches wavelengths of RGB-LED backlight for TFT-LCD. l 3 ch current-to-voltage amplifiers Simultaneous output of 3 ch RGB photocurrent l Configuration and size suitable for side mounting to TFT-LCD l Suitable for lead-free solder l Pin compatible with previous device l Low current consumption
Applications
l Built-in RGB color sensor
l RGB-LED backlight monitor for TFT-LCD
