Abstract
A light-emitting unit includes a multilayer circuit structure, a plurality of display pixels, and at least one compensation pixel. The multilayer circuit structure includes a top circuit layer and a bottom circuit layer. The display pixels are arranged into an N×M pixel array along a first direction and a second direction. Each of the display pixels includes a plurality of sub-pixels. The sub-pixels are disposed on the top circuit layer of the multilayer circuit structure. The compensation pixel is disposed on the top circuit layer of the multilayer circuit structure and electrically bonded to the multilayer circuit structure. The compensation pixel is located between the display pixels. The number of the compensation pixel is less than the number of the display pixels. Extension lines in the first direction and the second direction do not pass through the compensation pixel. A display apparatus is also provided.
