Problems solved by technology

But when the phenomenon that the output energy of the laser beam 10 decreases occurs, it is difficult to judge the position that causes the output energy of the laser beam 10 to decrease.
In addition, there is also the difficulty of readjusting the reduced output energy of the laser beam to the desired intensity

Abstract

The present invention relates to a device for adjusting laser output and a method thereof, wherein the device for adjusting laser output comprises a laser unit (100) generating laser beam (10); an optical unit (200) providing a laser beam path (10); a machining unit (300) irradiating the laser beam passing through the optical unit (200) to a substrate (20); a first measuring unit (400) arranged between the laser unit (100) and the optical unit (200) and used for measuring the output energy of the laser beam (10) of the laser unit (100); a second measuring unit (500) arranged inside the optical unit (200) and measuring the output energy of the laser beam (10) passing through the optical unit (200); a control unit (600) receiving the output signals of the laser beam measured by the first measuring unit (400) and the second measuring unit (500) and transmitting the signals to the laser unit (100), in order to adjust the output energy of the laser beam (10) generated at the laser unit (100).

Description

technical field [0001] The invention relates to a laser output adjustment device and method. More specifically, it is a laser output adjustment device and method capable of easily adjusting the output energy of the laser beam irradiated on a substrate by measuring the laser beam generated in the laser unit by the first measurement unit and the second measurement unit. Background technique [0002] In recent years, with the increase in demand and the trend of large-scale flat panel display devices, especially in liquid crystal displays (LCD), the application degree, size increase and resolution increase speed are also accelerating, and in order to improve production efficiency and Achieving low prices has put a lot of effort into simplifying the manufacturing process and increasing yield. The basic structure of a liquid crystal display consists of an upper substrate formed with a black matrix, a color filter film, and a common electrode, and a lower substrate formed with pix...
