  • Patent number: 11978410
    Abstract: A method of backlight control for a display panel is provided. The display panel is configured to display with a variable refresh rate in a plurality of frame periods each having a fixed period and a variable period. The method includes steps of: generating a first backlight control signal in the fixed period of a frame period; determining whether a liquid crystal (LC) transition time corresponding to the frame period ends before an end time of the variable period of the frame period; generating a second backlight control signal in the variable period of the frame period when the LC transition time ends before the end time of the variable period of the frame period; and generating a compensation backlight control signal in a next frame period according to a backlight duty cycle of the frame period.

  • Patent number: 11978751
    Abstract: An electrode controls transmittance of a blocking layer over a photodiode of a pixel sensor (e.g., a photodiode of a small pixel detector) by changing oxidation of a metal material included in the blocking layer. By using the electrode to adjust transmittance of the blocking layer, pixel sensors for different uses and/or products may be produced using a single manufacturing process. As a result, power and processing resources are conserved that otherwise would have been expended in switching manufacturing processes. Additionally, production time is decreased (e.g., by eliminating downtime that would otherwise have been used to reconfigure fabrication machines.

    Abstract: A biological particle enrichment apparatus and a pico-droplet generator thereof are provided. The pico-droplet generator includes a container, a hollow needle connected to the container, a first piezoelectric member disposed on the container, and a second piezoelectric member disposed on the hollow needle. The container can receive a liquid specimen having biological particles. The hollow needle and the container are fluid communicated with each other, and an inner diameter of the container is within a range from 5 times to 30 times of an inner diameter of the hollow needle. The first piezoelectric member is annularly disposed on a surrounding lateral side of the container, and enables the biological particles in the container to move along a direction away from the surrounding lateral side by vibrating the container. The second piezoelectric member can squeeze the hollow needle, so that the liquid specimen flows outwardly to form a pico-droplet.

  • Patent number: 11935722
    Abstract: This disclosure is directed to solutions of detecting and classifying wafer defects using machine learning techniques. The solutions take only one coarse resolution digital microscope image of a target wafer, and use machine learning techniques to process the coarse SEM image to review and classify a defect on the target wafer. Because only one coarse SEM image of the wafer is needed, the defect review and classification throughput and efficiency are improved. Further, the techniques are not distractive and may be integrated with other defect detecting and classification techniques.
