Publication number: 20240062731Abstract: An electronic device includes a display panel, a backlight source, an ambient light sensor, and a controller. The backlight source is disposed below the display panel and includes light-emitting units. The ambient light sensor detects the brightness of the ambient light. The controller judges the modes of the electronic device according to the detecting results of the ambient light sensor. When the electronic device is in a low-brightness mode, the brightness of a white frame of the display panel is greater than 0 nit and less than or equal to 50 nits, and in a general mode, the brightness of the white frame of the display panel is greater than 50 nits. The backlight source includes a local dimming function. When in the low-brightness mode, the local dimming function is in a first mode. When in the general mode, the local dimming function is in a second mode.Type: ApplicationFiled: July 18, 2023Publication date: February 22, 2024Inventors: Chao-Chin SUNG, Hsin-Cheng HUNG, Chien-Tzu CHU, Li-Wei SUNG

Patent number: 11619656Abstract: A probe head includes a middle die, upper and lower die units, at least one of which includes inner and outer dies detachably fastened to the middle die and each other, and a plurality of buckled probes inserted through the upper and lower die units. The inner die has an outer connecting surface connected with an inner surface of the outer die, where an installation recess is provided, an inner connecting surface connected with the middle die, and a probe installation section having a protruding portion protruding from the outer connecting surface and located in the installation recess, and a recessed portion recessed from the inner connecting surface and located correspondingly to the protruding portion. The protruding portion and the installation recess have a horizontal distance therebetween. Therefore, the outer die is horizontally fine adjustable to make the positions of the probes meet the requirement.Type: GrantFiled: December 29, 2021Date of Patent: April 4, 2023Assignee: MPI CORPORATIONInventors: Chin-Yi Lin, Keng-Min Su, Che-Wei Lin, Hsin-Cheng Hung
