Abstract
A defective pixel correction apparatus has a laser output section and a measurement mechanism. The laser output section has an adjustment function of adjusting an intensity of a laser beam. The measurement mechanism measures an intensity of a laser beam reflected from a defective pixel.
Claims4
A defective pixel correction apparatus which irradiates a laser beam on a defective pixel in a liquid crystal panel, to correct the defective pixel, comprising:
- a laser output section which outputs a laser beam and has an adjustment function of adjusting an intensity of the laser beam;
- and
- a measurement mechanism which measures an intensity of the laser beam reflected by the defective pixel.
A defective pixel correction apparatus which irradiates a laser beam on a defective pixel in a liquid crystal panel, to correct the defective pixel, comprising:
- a laser output section which outputs a laser beam and has an adjustment function of adjusting an intensity of the laser beam;
- and
- a monitor section including
- a light source which outputs light for monitor toward the defective pixel,
- a band-pass filter which allows a part of light reflected by the defective pixel and having a particular wavelength to pass, and
- a pickup section which picks up the light reflected by the defective pixel and having passed through the band-pass filter.
