The third electrode and the fourth electrode are disposed between the black matrix and the liquid crystal layer. The second linear electrodes extend in a second direction and each overlap a portion of the black matrix extending in the second direction. The fourth electrode is disposed between the second linear electrodes and overlaps the black matrix in a plan view. The control circuit switches between application of driving voltage and application of constant voltage to the third electrode.Type: GrantFiled: January 3, 2023Date of Patent: February 27, 2024Assignee: Sharp Display Technology CorporationInventors: Koji Murata, Hiroshi Tsuchiya, Shinpei Higashida, Takahiro Sasaki, Takashi Satoh, Shinji Shimada

Publication number: 20230388703Abstract: The present technique relates to an earhole-wearable sound collection device, a signal processing device, and a sound collection method for realizing sound collection at a high S/N ratio, with noise influence being reduced not by a noise reduction process. In the earhole-wearable sound collection device, a microphone that collects emitted speech voice is provided in a space that is substantially sealed off from outside and connects to an ear canal of the wearer (the speaker). With the microphone being located in the space sealed off from outside, emitted speech voice that propagates through the ear canal of the wearer is collected. In a sound collection signal obtained through the ear canal, the emitted speech voice component is dominant over the noise component particularly at low frequencies. Therefore, the S/N ratio of an emitted speech voice collection signal can be improved by extracting the low-frequency component of the sound collection signal with the use of a LPF, for example.Type: ApplicationFiled: August 8, 2023Publication date: November 30, 2023Inventors: KOHEI ASADA, SHINPEI TSUCHIYA, DAIZEN KOBAYASHI, KOJI NAGENO
