摘要
Embodiments of the present invention relate to a color temperature tuning method, a color temperature tuning apparatus, and a display apparatus. The color temperature tuning method includes the steps of: matching an input color temperature signal with a color temperature value in the color temperature lookup table, and extracting a current signal corresponding to the color temperature value matching with the input color temperature signal from the color temperature lookup table; and controlling a light emitting device to emit light according to the current signal. According to embodiments of the present invention, intermediate calculation process is omitted and time for tuning the color temperature is shorten. Currents flowing through the blue and green light emitting elements are controlled to emit lights to excite red fluorescent powder, so that the LED emits lights having various color temperatures, and tuning accuracy of the color temperature and user experience are improved.
