APPARATUS FOR INSPECTING DISPLAY PANEL AND METHOD FOR INSPECTING DISPLAY PANEL - A simplified explanation of the abstract
This abstract first appeared for US patent application 18105575 titled 'APPARATUS FOR INSPECTING DISPLAY PANEL AND METHOD FOR INSPECTING DISPLAY PANEL
Simplified Explanation
The patent application describes an apparatus for inspecting a display panel using various optical components and imaging technology.
- The apparatus includes a light source that emits a beam of light.
- A half mirror is used to reflect a portion of the light beam and transmit another portion towards the display panel.
- A reflective mirror is positioned to reflect the transmitted portion of the light beam back towards the half mirror and the display panel.
- A panel supporter is used to hold the display panel in place between the half mirror and the reflective mirror.
- A wave plate is placed between the half mirror and the reflective mirror to transmit the light beam.
- A rotator is included to rotate the wave plate at a specific angle.
- An imaging detector is used to capture an interference fringe created by the interaction of the reflected and transmitted light beams.
Overall, this apparatus allows for the inspection of display panels using a combination of optical components and imaging technology to capture interference fringes for analysis.
Original Abstract Submitted
An apparatus for inspecting a display panel includes a light source, a half mirror reflecting a first beam which is a portion of a source beam irradiated from the light source and transmitting a second beam which is another portion of the source beam toward a display panel, a reflective mirror reflecting the second beam transmitting the half mirror and the display panel to return to the half mirror, a panel supporter supporting the display panel between the half mirror and the reflective mirror, a wave plate disposed between the half mirror and the reflective mirror and transmitting the second beam, a rotator rotating the wave plate at a predetermined angle and an imaging detector photographing an interference fringe by the first beam and the second beam.
