  • Publication number: 20250022431
    Abstract: Disclosed are a driving method for a display device and the display device. In an image display process, when a brightness change is generated in a local area of a display image, a first brightness of a current display image is determined; a first driving current corresponding to the first brightness is determined according to the first brightness and the predetermined relationship between the brightness and a driving current; a duty ratio of the first driving current of each partition in a backlight module corresponding to areas other than the local area of the display image is adjusted; and a light source in each partition is driven by using the adjusted first driving current and duty ratio to emit light, such that the brightness of the display image in other areas is kept unchanged.

  • Publication number: 20240296314
    Abstract: A generative artificial intelligence (AI) model application programming interface (API) receives a generative AI request and routes the generative AI request to a generative AI model. The generative AI model API identifies whether the generative AI request is an asynchronous or a synchronous request and identifies a likely length of generation requested by the generative AI request. The generative AI model API evaluates the available capacity of generative AI models in a shared pool of computing system resources based upon the generative AI model type requested by the generative AI request and based upon the length of the requested generation. The generative AI model API routes the generative AI request to a generative AI model based upon the available capacity, whether the generative AI request is synchronous or asynchronous, the generative AI model type, and the length of the requested generation.
