A light-merging control unit applied in a backlight module. The backlight module comprises first and second light emitting units respectively driven by first and second frequencies. Light from the first and second light emitting units is merged into merged light. The light detector detects the merged light and generates a detection signal. The controller calculates the power of the first and second frequencies according to the detection signal. The controller controls the first driver to adjust the power of the first frequency and the second driver to adjust the power of the second frequency.
