Abstract

A display panel, on which a cutting area is defined, the display panel includes a base substrate, a shorting bar arranged on the base substrate, and an organic planar layer arranged on the shorting bar, the shorting bar includes at least one slit-shaped opening, A slit-like opening is located in the cutting area. By designing the part of the cutting area corresponding to the shorting bar to have a structure with a slit-like opening, the cutting process is made easier, thereby reducing laser cutting energy and cost, and removing part or all of the organic flat layer corresponding to the shorting bar, The laser cutting energy can be further reduced, and the reliability of the laser cutting process can be improved at the same time.

Description

Display panel and method of making the same technical field [0001] The present application relates to the field of display technology, and in particular, to a display panel and a preparation method thereof. Background technique [0002] In order to find abnormal display in advance of the liquid crystal display in the manufacturing process, it is usually drawn in the Cell (liquid crystal cell) section. For quality inspection, a Shorting bar structure is generally designed for image quality inspection. Perform COF on the display module (Chip on Film, chip on film) The shorting bar line needs to be cut off before bonding. However, at present, for liquid crystal display Under the requirements of high resolution and high refresh frequency of the monitor, the metal film thickness is continuously increasing, and the organic film layer technology is widely used in the industry. It requires high laser (laser) energy to cut off the organic film and metal lines, resulting in a ...
