Abstract
A display unit includes a display panel, a printed circuit board having at least one first light-emitting element configured to illuminate the display panel, and a light guide member having a light incident surface facing the first light-emitting element and a light outgoing surface facing a rear side of the display panel. The light outgoing surface is closer to an edge of the display panel than the light incident surface in a direction parallel to the printed circuit board. A household appliance having the display unit is also provided.
Claims13
A display unit configured for a household appliance, the display unit comprising:
- a display panel having a rear side and an edge;
- a printed circuit board including at least one first light-emitting element configured to illuminate said display panel;
- a light guide member including a light incident surface facing said at least one first light-emitting element and a light outgoing surface facing said rear side of said display panel;
- said light outgoing surface being closer to said edge of said display panel than said light incident surface in a direction parallel to said printed circuit board;
- and
- a peripheral wall disposed between said printed circuit board and said display panel in a direction perpendicular to said display panel, said peripheral wall having a window, and said light guide member being disposed in said window.
A display unit configured for a household appliance, the display unit comprising:
- a display panel having a rear side and an edge;
- a printed circuit board including at least one first light-emitting element configured to illuminate said display panel;
- a light guide member including a light incident surface facing said at least one first light-emitting element and a light outgoing surface facing said rear side of said display panel;
- said light outgoing surface being closer to said edge of said display panel than said light incident surface in a direction parallel to said printed circuit board;
- a bracket located behind said display panel, and at least one of:
- said bracket includes at least a part of a peripheral wall defining the display unit, said peripheral wall having a window configured to accommodate said light guide member, or
- said bracket includes a receiving slot configured to receive said light guide member, said receiving slot being open on a front side facing said display panel and on a peripheral side, or
- said bracket accommodates said light guide member clamped in said bracket, or
- said bracket has an elastic arm, and said light guide member has a hook portion matching said elastic arm.
A display unit configured for a household appliance, the display unit comprising:
- a display panel having a rear side and an edge;
- a printed circuit board including at least one first light-emitting element configured to illuminate said display panel;
- a light guide member including a light incident surface facing said at least one first light-emitting element and a light outgoing surface facing said rear side of said display panel;
- said light outgoing surface being closer to said edge of said display panel than said light incident surface in a direction parallel to said printed circuit board;
- and
- wherein at least one of:
- said light guide member is exposed outside the display unit, or
- at least a part of a section of said light guide member between said light incident surface and said light outgoing surface extends obliquely, enabling a transmission path of light in said light guide member to be at a distance in a direction parallel to said display panel.
