Description

Display panel and electronic device including the same The present invention relates to a display panel and an electronic device including the same, and more specifically, to an electronic device including a display panel with simplified manufacturing processes and improved display quality. Generally, electronic devices that provide video to users, such as smartphones, digital cameras, laptop computers, navigation systems, and smart televisions, include electronic devices for displaying video. The electronic device generates video and provides the generated video to the user through a display screen. The electronic device includes a plurality of pixels for generating an image and a plurality of lines connected to the pixels. The pixels are driven by receiving driving signals through the lines. Large-sized electronic devices, such as tablets and smart televisions, may experience differences in the driving voltage delivered to each pixel, requiring a design to compensate for this.
