LCD screen laser machine-The first article
With the explosive growth of consumer electronics, smart terminals,
and in car display markets, the manufacturing process of
liquid crystal displays (LCD/LEDs) continues to evolve towards high
precision and efficiency. In this context, laser machines have gradually
become one of the core equipment in LCD screen production lines due
to their advantages of non-contact processing, ultra precision,
and intelligent control. This article will analyze the key role of laser
machines in LCD screen manufacturing from three aspects:
technical principles, application scenarios, and industry trends.
Technical analysis: The core advantages of laser machines
Laser machine is a device that uses high-energy laser beams to
perform precision machining such as cutting, etching, annealing,
etc. on materials. In the manufacturing of LCD screens,
its core values are reflected in the following aspects:
1. Micron level machining accuracy
The laser focusing spot can be controlled below 10 μ m,
which can accurately complete processes such as PI film cutting,
ITO glass etching, polarizer cutting, etc., avoiding problems such
as edge breakage and burrs caused by traditional mechanical blades,
and significantly improving the yield rate.
2. Non contact processing
Laser directly acts on the surface of materials through photothermal effect,
without physical contact, avoiding stress damage to brittle glass
substrates caused by traditional cutting, especially suitable for
the processing of new display panels such as flexible OLEDs.
3. Intelligent process integration
By combining CCD visual positioning system and AI algorithm,
the laser machine can achieve automatic alignment, path optimization,
and real-time quality monitoring, adapt to high-density and irregular
cutting requirements, and meet TV needs, LCD、 Complex designs
such as splicing screens, curved screens, and car mounted curved screens.
4. Environmentally friendly and efficient
No consumables loss, no dust pollution during the processing,
and the single machine efficiency can reach that of traditional
equipment, which is in line with the trend of intelligent manufacturing and green production.

Product application
Mainly in the mirror through the high frequency pulse laser beam of
the LCD internal semiconductor circuit of the micron size of cutting
and trim especially passivation layer (silicon oxide / nitride) and metal
interconnection to achieve the role of line maintenance, the device can
adjust the laser pulse energy and wavelength for different target materials.
Equipment use
It is mainly caused by the internal line defects of the LCD screen,
including LCD screen highlights, vertical line, horizontal line,
cross line, half line, black screen, gray screen, screen thickness,
picture jitter, uneven display, and a series of screen and internal line problems of the screen substrate.
Laser type: single channel modulation Q (crystal 6MM)
