Abstract: A display device including a driving chip and a pixel array is provided. The driving chip is configured to provide multiple emission control signals according to a data input. A pixel array is coupled with the driving chip. M pixel circuits of the pixel array are configured to emit light respectively in M periods, and M is a positive integer. In a corresponding period of the M periods, the driving chip determines a first time length which one of the multiple emission control signals has a first voltage level, and one of the M pixel circuits emits light, in the corresponding period, for a light emission time length corresponding to the first time length.

Abstract: The present disclosure provides a semiconductor device, including a buffer layer, a first sub-chip and a second sub-chip, and a connecting element. The first sub-chip and the second sub-chip are separately arranged on the buffer layer. Each of the first sub-chip and the second sub-chip includes a first diffusion layer, an active layer, and a second diffusion layer. The first diffusion layer, the active layer, and the second diffusion layer are sequentially arranged on the buffer layer in a top-down approach. The first diffusion layer and the buffer layer are first-type epitaxial layers, and the second diffusion layer is a second-type epitaxial layer. The connecting element is configured to couple the second diffusion layer of the first sub-chip and the first diffusion layer of the second sub-chip.
