Publication number: 20240122019Abstract: A display device includes a display panel, an input sensor, and a circuit board. The input sensor includes first detection electrodes arranged in a first direction, second detection electrodes arranged in a second direction, first detection wires respectively electrically connected to the first detection electrodes, and second detection wires respectively electrically connected to the second detection electrodes. Resistance values of the first detection wires decrease as a corresponding first detection electrode among the first detection electrodes is disposed closer to a center of the display panel. Resistance values of the second detection wires increase as a corresponding second detection electrode among the second detection electrodes moves away from the circuit board, and a difference between the resistance values of the second detection wires adjacent to each other increases as the corresponding second detection electrode moves away from the circuit board.Type: ApplicationFiled: June 29, 2023Publication date: April 11, 2024Inventors: GAYEON YUN, Bongil KANG, Taejoon KIM
