Title:
MASK, DISPLAY PANEL AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/206084
Kind Code:
A9
Abstract:
The present disclosure relates to a mask, a display panel and a display device. By means of providing a universal first opening (121) in a mask main body (12) and matching a sheet (13) which is provided with different kinds of second openings (131), a mask (1) applicable to stretching different patterns to be formed is formed, thereby reducing the number of mask main bodies (12). In addition, due to an increase in the size of the first opening (121), the first opening (121) is also relatively easy to process even in a thicker mask main body (12). Although the second openings (131) are small, the sheet (13) is relatively thin; therefore, the processing difficulty is relatively low. In summary, where the number of mask main bodies (12) is decreased and the processing difficulty of the single mask (1) is reduced, the cost of the mask (1) that is required for processing graphic units of different patterns to be formed is relatively low. (FIG. 5)
