Abstract

The invention provides laser cutting equipment for cutting a flexible display panel, which is provided with a precutting mark. The laser cutting equipment comprises a working platform, a laser source,and a mobile part connected to the laser source; the flexible display panel is positioned on the working platform towards the laser source; the laser source is provided with a one-way transmitting film towards a lens in a lens light inlet direction; the mobile part drives the laser source to move along the precutting mark of the flexible display panel; and laser generated by the laser source penetrates through the one-way transmitting film for cutting along the precutting mark of the flexible display panel. The laser cutting equipment can protect the lens of the laser source when improving the utilization rate of laser energy.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a laser cutting device and a laser cutting method. Background technique [0002] With the advancement of display technology, flexible organic light-emitting diode display screens have gradually become the mainstream. In the cutting process of display panels, laser cutting is more and more widely used. The current principle of laser cutting is: the high-frequency and high-energy pulsed laser interacts with the display panel, and the display panel is cut by generating high temperature. The advantages of laser cutting are fast, high precision, non-contact, pollution-free, material-saving and many other advantages. However, during the laser cutting process, part of the laser light is reflected by the display panel, resulting in low energy utilization and damage to the lens of the laser source. Contents of the invention [0003] The object of the present invention is to provide a...
