摘要： An input sensing unit that utilizes conductive layers to sense various types of input. The input sensing unit may include a first conductive layer including first sensing electrodes; a second conductive layer disposed on the first conductive layer, the second conductive layer including second sensing electrodes and third sensing electrodes; and at least one insulating layer insulating the first conductive layer and the second conductive layer from each other. The input sensing unit senses at least one of a touch, a pressure, and a degree of moisture based on a change in capacitance between the conductive layers.

摘要： A fingerprint sensor includes a light sensing layer having a light sensing element in which a sensing current flows in response to incident light and a light guide layer disposed on the light sensing layer. The light guide layer includes first light-transmitting films spaced apart from one another, a light-blocking film disposed between the first light-transmitting films, and a second light-transmitting film disposed between each of the first light-transmitting films and the light-blocking film.
