A kind of panel display module source using RGB LED as backlight is introduced in this pa-per.Frequency diming method is used to adjust backlight brightness.The final standard white light is gained by RGB diming pulse high level mixing color method.And besides,RGB diming pulse high level timing is tuned according to data from color sensor.Using the method,backlight brightness, color varies and coordinates drifts caused by temperature varies can be effectively improved.
