  • Publication number: 20210063737
    Abstract: Provided is a near-eye display device including: a base substrate including first and second surfaces opposite to each other, an optical element array on the first surface, and a pixel island array and a sensor array that are on the second surface and are coupled to each other. The pixel island array emits first pixel light to the optical element array, such that the first pixel light passes through the optical element array and then reaches a human eye. The sensor array receives light of the first pixel light reflected by the human eye, determines a position of a pupil center of the human eye according to an intensity distribution of the reflected light, determines pixels corresponding to the position of the pupil center in the pixel island array, and controls the pixels to emit second pixel light.

  • Publication number: 20200363321
    Abstract: A spectrometer and a micro-total analysis system are provided. The spectrometer includes a waveguide structure, a light source, a collimating mirror, a reflection grating, and a light extraction structure. The collimating mirror is configured to convert light, which is emitted from the light source, passes through the waveguide structure, and is incident on the collimating mirror, into collimating light. The reflection grating is configured to allow emergency angles of light of different wavelength ranges among the collimating light incident on the reflection grating to be different, so that the light of different wavelength ranges has an offset in the total reflection propagation process. The light extraction structure is located on the reflection surface of the waveguide structure through which the light of different wavelength ranges passes in the total reflection propagation process, so that the light of different wavelength ranges emits from the light extraction structure.

  • Publication number: 20200232910
    Abstract: A fluid detection panel and a fluid detection device are disclosed. The fluid detection panel includes a fluid-driven substrate, a filter structure and a sensor. The filter structure is configured to filter light emitted by a light source; the fluid-driven substrate comprises a detection area, and is configured to enable a liquid sample to move to the detection area; the sensor is configured to receive light which is emitted by the light source and sequentially passes the filter structure and the detection area.
