  • Publication number: 20150331176
    Abstract: A front light guide includes a light guide plate, a light source, a functional material layer and a first adhesive layer. The light guide plate has a side surface, a first surface and a second surface opposite to the first surface. The light guide plate has a first refractive index. The light source faces the side surface and configured to emit light into the light guide plate. The functional material layer is disposed at a side adjacent to the first surface, and has a third refractive index. The first adhesive layer is interposed between the light guide plate and the functional material layer so as to adhere the light guide plate with the functional material layer. The first adhesive layer has a second refractive index. The first refractive index is greater than the second refractive index, and the second refractive index is greater than the third refractive index.

  • Publication number: 20150117054
    Abstract: A display device includes a display panel, a light guide plate (LGP), a light source, and a positioning component. The LGP is disposed on a display surface of the display panel and has an upper surface and a lower surface opposite to each other, a light-incident surface, a first light-guiding block, and a second light-guiding block. A display area of the display panel corresponds to the first light-guiding block. The second light-guiding block extends outside the display area and has at least one recess portion. The recess portion is located on at least one of the upper surface and the lower surface and extends to the light-incident surface. The light source is disposed beside the light-incident surface. The positioning component is disposed on the second light-guiding block and located in the recess portion. Besides, the positioning component extends outside the recess portion and fixes the location of the light source.

  • Publication number: 20150117055
    Abstract: A display apparatus is provided. A display unit has a display region. A protecting cover has a patterned region, wherein the patterned region does not overlap the display region. A light guide plate is disposed between the display unit and the protecting cover and has a first light scattering region and a second light scattering region. The first light scattering region at least partially overlaps the display region, and the second light scattering region at least partially overlaps the patterned region. A light emitting unit emits a light beam to the light guide plate. After the light beam enters the light guide plate, a part of the light beam is scattered to the display region by the first light scattering region and another part of the light beam is scattered to the patterned region by the second light scattering region.

  • Publication number: 20140286045
    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.

  • 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.
