Abstract
A system for testing a distortion of a liquid crystal display (LCD) device can test the LCD device within a chamber in a state of being assembled perpendicular to the ground, whereby whether any distortion occurs in an internal component can be fast detected even in severe conditions of high temperature and high humidity and under an actual installation environment of a user.
Claims9
A system for testing a distortion of a liquid crystal display (LCD) device, comprising:
- a fixing unit that fixes the LCD device perpendicular to the ground;
- a laser sensor at front side or rear side of the LCD device that irradiates light to the LCD device to measure a displacement of an internal component thereof;
- a conveyer at a front side or rear side of the LCD device to convey the laser sensor in horizontal and vertical directions;
- and
- a controller that detects a position of an internal component of the LCD device based upon information input by the laser sensor, and comparies the detected position with a preset position of the corresponding internal component to determine a distortion of the component.
