A mask apparatus for evaporation of an organic material of an organic light emitting diode display comprises: a mask plate frame (20) and multiple sub-mask plates (22) mounted on the mask plate frame (20), gaps (24) being provided between the sub-mask plates (22), the gaps (24) between every two adjacent sub-mask plates (22) being the same, the mask plate frame (20) being in a rectangle shape, and a rectangular accommodation mouth (200) being provided in the middle, the number of the sub-mask plates (22) being determined according to the width of the accommodation mouth (200) of the mask plate frame (20) and the width of the sub-mask plate (22), and the value obtained by adding the width of all sub-mask plates (22) to the width of the gaps (24) therebetween is greater than or equal to the width of the accommodation mouth (200). By using the mask apparatus, the multiple sub-mask plates (22) are spliced on the mask plate frame (20), thereby implementing the large size of the mask for evaporation of the organic material of the organic light emitting diode display, and facilitating evaporation of an organic material of a large-size organic light emitting diode display. |
