Problems solved by technology

[0004] However, using a special-shaped mask to evaporate the substrate to be evaporated will not only increase the difficulty of making the mask, but also make it difficult to guarantee the manufacturing accuracy of the mask. It is difficult to control the alignment accuracy of the vapor-deposited substrate at the irregular shape, which makes the position of the vapor-deposited light-emitting layer deviate, which in turn leads to color mixing in the display panel

Abstract

The embodiment of the connection provides a supporting bar used for a display panel, a supporting device and an evaporation method of the display panel, and relates to the technical field of display. The manufacture difficulty of a mask is lowered, and accuracy of coating is also improved. The supporting bar mentioned above comprises a supporting body and shielding parts. On the plane where the orthographic projection of the supporting body is located, the shielding parts protrude on the first side of the supporting body, and each shielding part is provided with a half etching groove. The supporting bar is used for supporting the mask.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to a support bar for a display panel, a support device and an evaporation method for the display panel. 【Background technique】 [0002] Most of the traditional display panels have a rectangular structure. However, with the continuous development of display technology and the diversified demands of users on the shape of the display panel, display panels with special shapes have been more and more widely used. [0003] For special-shaped display panels, when evaporating the light-emitting layer of the substrate to be evaporated, it is necessary to use a mask with the same shape as the mask. The mask is placed on the support bar, aligned with the substrate to be evaporated, and evaporated The source is evaporated to the opening area of ​​the substrate to be evaporated through the opening of the mask to form a light emitting layer. [0004] However, using a special-shaped mask to ev...
