In a first display device and a second display device of a display mechanism, a first video image and a second video image having mutually different display contents are visually recognized, and further, display positions of the first video image and the second video image can be changed by first and second posture adjustment mechanisms that are a posture adjustment mechanism.

Head-mounted display device

In a left and right pair of a first display device and a second display device that perform repositionable display, mutually different display contents can be visually recognized as a first video image and a second video image. Further, a display control portion controls the display content in accordance with at least one of the first video image and the second video image.

A scanning line driving circuit selects arbitrary one of a plurality of pixels and causes the pixel to perform a current value setting operation of setting a current value of the driving current to be supplied to the light emitting element of the pixel in a frame period before the pixel is selected again and a light emission operation of emitting light by supplying the driving current to the light emitting element. The scanning line driving circuit controls, in common with the plurality of pixels, a duty ratio corresponding to the frame period of the light emission period in which the light emission operation is performed. The scanning line driving circuit disperses time differences between a current value setting timing and a start timing of the light emission period in the plurality of pixels when the duty ratio is equal to or smaller than a predetermined value.

Electro-optical apparatus, electronic apparatus, and method for driving electro-optical apparatus

An electro-optical apparatus includes a plurality of display portions and a control portion. The respective display portions have a plurality of pixels. Each of the plurality of pixels has a light-emitting element that emits light using current that is input at a predetermined cycle from a power supply line in a period from selecting a scanning line until selecting the subsequent scanning line. The control portion controls the display portions such that one of an input number of times of current from the power supply line to the light-emitting element in the period and an input time of current from the power supply line to the light-emitting element in each of the predetermined cycles changes in conjunction with each other in the display portions that are different from each other and the other changes independently from each other in the display portions that are different from each other.
