Tianhang LUAN has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Temperature sensor, array substrate and display device
    Patent number: 11255732
    Abstract: Provided are a temperature sensor, an array substrate, and a display device. In the temperature sensor, a low-pass filter is disposed between a ring oscillator and a comparator, so that a square-wave signal output from the ring oscillator passes through the low-pass filter and a high-frequency component in the square-wave signal output from the ring oscillator is directly filtered out by the low-pass filter, thereby improving a signal-to-noise ratio of the ring oscillator and a test accuracy of the temperature sensor.
    Type: Grant
    Filed: September 4, 2018
    Date of Patent: February 22, 2022
    Assignee: BOE TECHNOLOGY GROUP CO., LTD.
