Patent number: 11568785Abstract: Disclosed is a display device for increasing an aperture ratio of a transmissive part. The display device includes data lines overlapping with one or more of the pixels emitting light to display an image. Each pixel includes subpixels arranged within the pixel along a same direction as the data lines. The display device further includes transmissive parts arranged in the first direction and corresponding to adjacent pixels. In addition to the data lines overlapping the pixels, the display device may include power lines and reference voltage lines parallel with the data lines and overlapping with the pixels. The display device may include scan lines and sensing lines arranged to cross the transmissive parts and data lines. As a result, the number of lines crossing the transmissive parts is reduced, thereby increasing an aperture ratio of the transmissive parts.Type: GrantFiled: February 22, 2022Date of Patent: January 31, 2023Assignee: LG Display Co., Ltd.Inventors: Jeong Hyeon Choi, Binn Kim, Joon Soo Han
