摘要： A display device includes a light emitting unit which generates and emits a first color light; an optical member in which the first color light which is incident from the light emitting unit is color-converted and from which color-converted light is emitted; and a display panel to which the color-converted light which is emitted from the optical member is provided. The optical member includes: a quantum dot member which transmits a portion of the first color light and color-converts a portion of the first color light into a second color light and a third color light; and a filter member between the light emitting unit and the quantum dot member, the filter member including a cholesteric liquid crystal layer which reflects the second color light or the third color light which is incident to the filter member from the quantum dot member.

摘要： An electronic apparatus includes a touch sensor, a driving circuit, and a switching circuit. The driving circuit includes a first detector and a second detector. The first detector transmits/receives an electrical signal to detect a position of a touch. The second detector transmits/receives an electrical signal to detect an intensity of the touch. The switching circuit selectively connects the first detector or the second detector to the sensor.
