Structure of Driving for a Sequential RGB Display

The invention sequentially related to a driving structure for the RGB display, receives the part of the light output from the red, blue and green light sources and outputting the light, and convert from one light receiving means to a current signal from a light receiving unit in the light source driver, according to the size of the feedback current provided to adjust the amount of current of the drive current applied to the respective light sources it will be controlled to be kept constant the light intensity of the light source. This is corresponding to a modulation signal (RGB) inputted by having sequential light emission and light reception in from each of the light sources, a simple structure to maintain always a constant light intensity, as well as possible to reduce the size of the light source display device changes in the change or the driving temperature of the ambient temperature, and it has the effect of increasing the advantage in terms of price competitiveness of products. A light source, modulation, a laser diode, a light source driver, a display
