description The invention relates to a device for improving mura of a silicon-based OLED screen, and the device comprises a light-emitting area profiling light-proof shielding block which is in a horizontal state, and the lower surface of the light-emitting area profiling light-proof shielding block is in direct contact with the upper surface of a to-be-cured light-emitting area of the OLED screen; the device further comprises at least one negative pressure adsorption hole; lower orifices of the negative pressure adsorption holes are located in the lower surface of the light-emitting area profiling lightproof shielding block, and the upper ends of the negative pressure adsorption holes are communicated with a negative pressure source. The device has the advantages that the device is simple in structure and low in required cost, generation of mura in the production process can be effectively and radically solved, and the device is short in time consumption, high in efficiency and high in rate of finished products; and the
