Display device for displaying images involving display pixels and non-display pixels
View Patent ↗Display devices for displaying images are provided. A representative display device incorporates a display panel that includes a display pixel and a non-display pixel. The display pixel includes at least one switching thin-film transistor and the non-display pixel includes dummy thin-film transistors. A number of the dummy thin-film transistors exceeds a number of the switching thin-film transistors.
