Abstract: A display apparatus includes a power supply device. The power supply device includes a power supply part and an integrated circuit chip. The power supply part outputs a first power to drive a backlight and a second power to drive a main circuit. The integrated circuit chip increases, based on a control signal to adjust a brightness of the backlight being received, a current value of the second power, and reduces, based on the control signal not being received for a first threshold time, the current value of the second power.

Abstract: A controller is provided. The controller creates a page table including page table entries including mapping information for translating a virtual address to a physical address. Each of the page table entries includes: a virtual page number, a physical frame number, valid information, and size information. The virtual page number is included in a virtual address, the physical frame number is included in a physical address, the valid information includes a first predetermined number of bits, and the size information includes a second predetermined number of bits. The first predetermined number of bits represents an address translation range in a page table entry or a number of page table entries to be grouped, and the size information represents a size indicated by each bit of the first predetermined number of bits.

Abstract: An image sensor includes a separation impurity layer in a semiconductor layer and defining a photoelectric conversion region and a readout circuit region, a photoelectric conversion layer in the semiconductor layer of the photoelectric conversion region and surrounded by the separation impurity layer, a floating diffusion region spaced apart from the photoelectric conversion layer and in the semiconductor layer of the photoelectric conversion region, a transfer gate electrode between the photoelectric conversion layer and the floating diffusion region, and impurity regions in the semiconductor layer of the readout circuit region. When the photoelectric conversion layer is integrated with photo-charges, the separation impurity layer has a first potential level around the photoelectric conversion layer and a second potential level on a portion between the photoelectric conversion layer and the impurity regions of the readout circuit region. The second potential level is greater than the first potential level.
