Abstract

A plastic frame component includes: a first frame strip, configured to match with a side edge of the display component to support the display device; a light source, disposed on the first frame strip and configured to emit light; and an optical path adjuster, disposed on the first frame strip. The first frame strip includes a first portion and a second portion that are connected to each other. The first portion and/or the second portion accommodate/accommodates the light source and the optical path adjuster, such that the first portion can protrude from the side edge of the display component and go beyond the display surface after the plastic frame component is assembled with the total reflection display component, and that the light emitted by the light source shines onto a display area of the display component after being adjusted by the optical path adjuster.
