Abstract: A first supply circuit outputs data signals to odd-numbered distribution circuits, and outputs selection signals to all of distribution circuits. A second supply circuit outputs data signals to even-numbered distribution circuits. The odd-numbered distribution circuits distribute the data signals to signal lines using the selection signals. The even-numbered distribution circuits distribute the data signals to signal lines using the selection signals. The first supply circuit outputs the data signals generated based on digital data signals which are basic signals of the data signals and an adjustment value, to the distribution circuits.

Abstract: A projector includes a liquid crystal panel, an optical path shifting element which is capable of changing the optical path of light emitted from the liquid crystal panel, and an image processing unit. The optical path shifting element performs pixel shift such that light reaches different positions of a display screen in respective first to fourth unit periods acquired by dividing one frame into four parts. The image processing unit includes a conversion unit which converts a high resolution image signal into a low resolution image signal, and generates an output image signal by performing an overdrive process on the low resolution image signal according to a pixel shift state.

Abstract: A projection-type display apparatus includes a liquid crystal panel including a panel pixel, an optical path shifting element that shifts a projected pixel projected from the panel pixel, and a display control circuit that controls the liquid crystal panel and the optical path shifting element. The display control circuit supplies, to the liquid crystal panel, the same data signal and controls the projected pixel to be at a same position in each of a unit period f1-1 and a unit period f2-1, and controls the optical path shifting element to cause a shift direction from the projected pixel before the shift toward the projected pixel after the shift from a unit period f1-2 to a unit period f1-4 to be opposite to the shift direction from the projected pixel before the shift toward the projected pixel after the shift from a unit period f2-2 to a unit period f2-4.
