Claim Text:
1. A color detection system of a display device comprising: a motherboard; a detection device comprising a display unit and a memory unit storing a first color frequency setting value corresponding to a first color, the display unit displays the first color according to the first color frequency setting value; and a detection card mounted on the display unit, and comprising a color sensor and a microcontroller connected to the color sensor, wherein the microcontroller is connected to the motherboard; the color sensor generates a first color frequency current value after sensing the first color from the display unit and sends the first color frequency current value to the microcontroller; the microcontroller sends the first color frequency current value to the motherboard and the motherboard outputs detection success information to the display unit when a first difference value between the first color frequency current value and the first color frequency setting value is less than a predetermined value; the display unit displays the detection success information.
