Abstract

A method for driving a novel display apparatus is provided. The method is a method for driving a display apparatus including a first layer and a second layer over the first layer. The first layer includes a plurality of driver circuit regions. The second layer includes a plurality of display regions. Each of the plurality of driver circuit regions includes a driver circuit. Each of the plurality of display regions includes a plurality of pixels. Each of the plurality of pixels includes a light-emitting element. The driver circuit included in one of the plurality of driver circuit regions has a function of driving each of the plurality of pixels included in one of the plurality of display regions. The method for driving the display apparatus includes: performing a first operation in which an operation of sequentially writing an image signal row by row in each of the plurality of display regions is performed and the operation is performed in all the plurality of display regions at the same time; performing a second operation in which the light-emitting elements included in the plurality of pixels are brought into a light-emitting state simultaneously after the first operation; and performing a third operation in which the light-emitting elements included in the plurality of pixels are brought into a non-light-emitting state simultaneously after the second operation.

Claims (31)
