Abstract

The present invention relates to a TPO sheet allowing display and touch sensing. More specifically, the present invention relates to a TPO sheet having a color and light-transmitting properties used as surface materials for automobile interior parts. According to the present invention, when the TPO sheet is used as surface materials for automobile interior parts, an interior decorative effect may be obtained due to color properties thereof. In addition, when the TPO sheet is attached to the surface of a display panel, due to light-transmitting properties thereof, light emitted from the display panel may be transmitted through the TPO sheet.
