Abstract: An adjustment method for a light emitting system and a light emitting system are provided. The light emitting system comprises a plurality of light emitting elements and a control circuit. Each of the light emitting elements has a corresponding lighting setting value. The adjustment method comprises: establishing correlation values between a target color temperature, which ranges from 1000K to 12000K, and the lighting setting values; summing the correlation values to generate a total and calculating a percentage of each of the correlation values relative to the total; and setting emission power of each of the light emitting elements according to the corresponding percentage of each of the light emitting elements. The mixed light that matches the target color temperature is then provided, and the color rendering index (CRI) of the mixed light has Ra>90.

Abstract: The invention relates to a display device which comprises a light source, a grid structure and a photo interrupter. The grid structure is disposed above the light source and can move left and right relative to the light source. When the grid structure does not block the photo interrupter, the light source receives a first signal, and when the grid structure blocks the photo interrupter, the light source receives a second signal.
