  • Patent number: 9329327
    Abstract: A display includes a reflective display module, a light guide plate, at least one light source and a cover lens. The light guide plate includes a first light guide surface opposite to the reflective display module. The first light guide surface includes a light outgoing region and a peripheral region surrounding the light outgoing region. The light source is used for emitting a light to the light guide plate. The peripheral region of the first light guide surface is connected to the cover lens. The light outgoing region and the cover lens are spatially separated, and define an air gap therebetween.

  • Publication number: 20160011359
    Abstract: A reflective display includes a display panel, a first color filter layer, a second color filter layer, a light guide plate, and a light source. The first color filter layer is disposed on the display panel; the second color filter layer is disposed on the display panel and arranged with the first color filter layer in parallel. The light source is disposed beside the side surface of the light guide plate and is capable of emitting light, in which and the light is reflected by the internal side of the first surface of the light guide plate, such that the light enters the first color filter layer, and the light is reflected by the display panel and emitted from the first color filter layer, in which optical path of the light passes through the first color filter layer and does not pass through the second color filter layer.

  • Patent number: 8834003
    Abstract: A display apparatus includes a display panel, a light guide plate, point light sources, a passivation layer and a first light adjusting layer. The light guide plate is disposed above the display panel and has an upper surface, an opposite lower surface, a light incident surface, a first and a second light guiding blocks. The display panel is disposed corresponding to the first light guiding block, and the second light guiding block extends outside the display panel. A portion of the upper surface located on the first light guiding block is an even surface. The first light guiding block is located between the passivation layer and the display panel. The first light adjusting layer is disposed on the second light guiding block and located on the upper surface or the lower surface. There is a first rough interface between the first light adjusting layer and the light guide plate.

  • Publication number: 20130258705
    Abstract: A front-light module includes at least one point light source, a light source modulation apparatus and a light guide plate. The light source modulation apparatus includes a body and a plurality of uniform illumination microstructures. The body includes a light incident surface and a light emission surface. The point light source is disposed beside the light incident surface, and the light emission surface is opposite to the light incident surface. The uniform illumination microstructures are disposed on the light emission surface of the body. Each uniform illumination microstructure is arc-shaped.
