Problems solved by technology

[0003] At present, it is necessary to align the display panel and the bending area during the bending process. By marking the lower layer of the bending area and opening an "O"-shaped hole with the same radius as the mark at the corresponding position, the charge-coupled device (charge- Coupleddevice, CCD) camera device through the hole to capture the mark of the complete bending area for accurate alignment, but the circuit board will be damaged during the drilling process and the alignment process will be complicated

Abstract

The embodiment of the invention discloses a display panel alignment method and a display panel preparation method. The method comprises the steps: a display panel is provided, wherein the display panel comprises a bending area; the display panel is marked to obtain a first mark; the bending area is marked to obtain a second mark; an alignment point is determined through the first mark and the second mark; and pre-alignment is conducted on the bending area and the display panel according to the alignment point. Alignment is carried out through the relation between the first mark and the alignment point and the relation between the second mark and the alignment point, complex procedures such as punching in a bending area are replaced, punching in the bending area is avoided, the damage rateof a circuit board is reduced, manufacturing procedures are reduced, and production efficiency is effectively improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel alignment method and a display panel preparation method. Background technique [0002] With the development of science and technology and the improvement of people's requirements for products, people's requirements for the screen ratio of the display are getting higher and higher, so the frame of the display is getting smaller and smaller. In Organic Light-Emitting Diode (OLED) products, in order to achieve a larger screen-to-body ratio, it is necessary to continuously reduce the bending radius of the bending area, bend and attach the OLED panel line terminal area to the product On the back, it achieves a narrow bezel display effect. [0003] At present, it is necessary to align the display panel and the bending area during the bending process. By marking the lower layer of the bending area and opening an "O"-shaped hole with the same radius as the mark at the c...
