The overall structure of the pixel points based on the quantum-dot color conversion film （QDCCF） was analyzed and designed using the simulation method. Firstly， the structure model of blue light micro light-emitting diode （Micro LED） was constructed. Besides， the surface microstructures， which included surface roughening and 2-D grating， were studied to enhance the light extraction efficiency （LEE） of the Micro LED. Moreover， the LEE and light intensity distribution of blue sub-pixels of the blue Micro LED with or without surface microstructure and the side-wall light-blocking medium under different side-wall angles were analyzed separately. Then， the parameters of the QDCCF were optimized， and the LEE and light intensity distribution of the red and green sub-pixels were analyzed in the Micro LED with different structures. Finally， the color shift of full-color pixels with different structures were compared and analyzed. The simulation results showed that the pixels with surface-roughening blue Micro LED and side-wall reflective light-blocking media could obtain a larger frontal LEE and a color shift of less than 0.02 at the angle of 0°~50°， which was more suitable for the QDCCF scheme compared with other structures.
