  • Aligning and assembling method of stereoscopic display device
    Patent number: 8810741
    Abstract: An aligning and assembling method of a stereoscopic display device is provided and includes providing a liquid crystal (LC) panel and a brightness detector. A lenticular panel is placed between the LC panel and the brightness detector. The LC panel is driven to output a light-dispersion pattern. The lenticular panel is rotated and the brightness detector obtains a plurality of brightness patterns and a plurality of light-dispersion periods generated from the light-dispersion pattern after the light-dispersion pattern has passed through the lenticular panel. The brightness patterns correspond respectively to the light-dispersion periods. A maximum light-dispersion period is found from the light-dispersion periods. The lenticular panel is stopped to rotate when the maximum light-dispersion period is found.
