  • Patent number: 10340098
    Abstract: A key structure, including a keycap, a movable mechanism, a support plate, a circuit board, and an indicator light-emitting element. The support plate and the movable mechanism pivotally connected to the support plate are disposed above the circuit board. The circuit board has a groove, and the indicator light-emitting element is embedded in the groove and is aligned with the keycap. The indicator light-emitting element emits light upward. The light may be directly emitted into the movable mechanism and is subsequently emitted outward through a light hole of the keycap.

  • Publication number: 20170248470
    Abstract: A calibration device for calibrating output of a display device includes a light source, an integrating sphere, a filter, a narrowband instrument, a wideband instrument, and a data processing unit. The light rays emitted by the light source passing through the filter and enter the integrating sphere. The narrowband instrument and the wideband instrument are configured to measure the color measured data. The data processing unit is configured to receive the color measured data to generate a calibration matrix based on the color measured. The calibration matrix is used to calibrate the output from the wideband instrument.

  • Publication number: 20110188036
    Abstract: The present invention relates to a monochromatic measurement system. The system mainly includes a monochromator, a light-detecting device and a filter device. The monochromator functions to split light under test into respective light beams with different wavelengths. The filter device modulates the transmission efficiency of the respective light beams, so that the wavelengths of the light beams to which the light-detecting device displays a better response have a lower transmission efficiency while the wavelengths of the light beams to which the light-detecting device displays a lower response have a higher transmission efficiency. The response values measured by the light-detecting device with respect to different wavelength intervals are normalized accordingly. The measurement errors attributed to the measurement precision of the instrument and the environmental noise are independent from the variation of wavelength. The reliability of the measurement instrument is elevated.

  • Patent number: 7495762
    Abstract: A high-density channels detecting device for detecting a sample is provided. The high density detecting-device has a light source for emitting a light beam, a collimator, a beam splitter, and a high-density channels imaging device. The collimator arranged on the beam path is used for collimating the emitted light beam. The beam splitter reflects the light beam incident from the collimator to the sample, and the light beam reflected by the sample passes through the beam splitter. The imaging device receives the light beam passing through the beam splitter, and has a light collector and a multi-channel kernel module for receiving the light beam from the light collector. By using the light collector, the light beam incident to the kernel module is parallel to the optical axis of the kernel module.
