Patent number: 11994961Abstract: An image display system includes a display device, a second memory circuit, and an image processor circuit. The display device includes a panel and a first memory circuit, in which the first memory circuit is configured to store first predetermined data for controlling the panel. The second memory circuit is configured to store second predetermined data. The image processor circuit is configured to read first part data in the first predetermined data and second part data in the second predetermined data and compare the first part data with the second part data. If the first part data is identical to the second part data, the image processor circuit is further configured to output a driving signal according to the second predetermined data to control the panel to start displaying an image.Type: GrantFiled: November 29, 2021Date of Patent: May 28, 2024Assignee: REALTEK SEMICONDUCTOR CORPORATIONInventors: Chia-Wei Yu, Chun-Hsing Hsieh

Patent number: 11095029Abstract: An antenna device includes first antenna units, second antenna units, first switching circuits and second switching circuits. The first antenna units generate radio frequency (RF) signals operating at a first frequency. The second antenna units generate RF signals operating at a second frequency. The first frequency is larger than the second frequency. The first switching circuits selectively enable at least one of the first antenna units. Each of the first switching circuits includes a first switch element and a second switch element. The first switch element is connected in parallel with an inductor. The second switch element is connected in parallel with another inductor. The second switching circuits selectively enable at least one of the second antenna units.Type: GrantFiled: September 24, 2019Date of Patent: August 17, 2021Assignee: PEGATRON CORPORATIONInventors: Chia-Hsing Hsieh, An-Shyi Liu

Patent number: 10840610Abstract: An antenna device includes antenna units, transmission lines and switching circuits. The antenna units are used to be operated in a directional mode or an omni-directional mode. The transmission lines are coupled to the antenna units. The switching circuits are coupled to the respective transmission lines, and are used for selectively connecting the transmission lines according to control signals. At least one transmission line is disconnected when the antenna units are operated in the directional mode. All the transmission lines are connected when the antenna units are operated in the omni-directional mode.Type: GrantFiled: January 23, 2019Date of Patent: November 17, 2020Assignee: PEGATRON CORPORATIONInventors: Chia-Hsing Hsieh, An-Shyi Liu
