Abstract
A display apparatus utilizing all light output by a light source also includes a display panel with a shield portion, a light guide plate, and a quantum dot enhancement layer. The display panel includes a display portion and a shield portion. The light guide plate is parallel with the display panel and guides light emitted by the light source to the display panel. The quantum dot enhancement layer converts a wavelength of the light and the shield portion is configured to reflect stray or escaping light back into the quantum dot enhancement layer for conversion. The surface of the light guide plate is overlapped with the shield portion for preventing any light leakage and the mixing of light of different wavelengths and thus colors is increased and improved.
