Abstract

The invention provides a laser etching device and a laser etching method. The laser etching device comprises a laser etching mode control module, a laser transmitting module, a beam expanding module and a scanning control module. Two or more expanding lenses are arranged in the beam expanding module. The laser etching device carries out switching between two or more laser spot sizes by controllingthe different expanding lenses to move into laser paths. The different expanding lenses corresponding to two or more laser etching modes are arranged in the beam expanding module, so that one laser etching device carries out switching between the two or more laser spot sizes. The laser etching process of a glass substrate is simplified, and the manufacturing cost and the mounting volume of the laser etching device are also reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a laser etching device and a laser etching method thereof. Background technique [0002] Two-dimensional bar code (2-dimensional bar code), also known as two-dimensional bar code, first originated in Japan. It is a black and white graphic distributed on a plane (two-dimensional direction) with a specific geometric figure according to certain rules. It is all information A key to the data. In modern commercial activities, a wide range of applications can be realized, such as: product anti-counterfeiting / traceability, advertisement push, website link, data download, commodity transaction, positioning / navigation, electronic voucher, vehicle management, information transmission, business card exchange, WIFI sharing etc. [0003] In the production of glass substrates in display panels, two-dimensional code patterns and line patterns usually need to be added for identification and c...
