Problems solved by technology

[0004] In the prior art, the way of waste discharge operation is mainly to absorb and remove the waste area (i.e. the dummy area) through the suction nozzle. Due to the limited adsorption capacity of the suction nozzle, the waste discharge operation requires that the width of the waste area should be at least about 4 mm. Therefore, Correspondingly, the cut-off area on the display panel should also have a width of at least 4mm, which will cause waste to the display panel, thereby reducing the utilization rate of the substrate substrate in the display panel, that is, resulting in a low layout rate of the display panel, which in turn increases production costs

Abstract

The invention provides a protective film, a mother film, a polarizer assembly and a preparation method thereof, a mother sheet assembly, and a preparation method of a display module, which can increase the typesetting rate of the display panel and reduce the waste discharge operation after cutting the display panel The difficulty makes the waste discharge work go on smoothly. The protective film includes: a diaphragm body; the diaphragm body includes: a central area, an edge area located on the periphery of the central area; wherein, the boundary between the central area and the edge area is provided so that the center A segmented line that easily separates the region from the edge region. For the preparation of protective film.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a protective film and a mother film, a polarizer assembly and a preparation method thereof, a mother sheet assembly, and a preparation method of a display module. Background technique [0002] According to the design requirements, after the display panel is prepared, it is usually necessary to adjust the edge of the display panel. [0003] (such as around or part of the sides) for cutting, for example, when the shape of the display panel is irregular, such as a rectangle with rounded corners or concave (ie Notch), it is necessary to perform special-shaped cutting on the display panel to complete After the cutting process, waste removal operation (hereinafter referred to as waste discharge operation) is required. [0004] In the prior art, the way of waste discharge operation is mainly to absorb and remove the waste area (i.e. the dummy area) through the suction nozzle. Due to t...
