Abstract: A display device includes a first light source module, a display panel and a transparent filling. The first light source module includes at least one first light source and a first light guide plate (LGP). The first LGP includes a first light-incident surface and a first light-emitting surface. The first light-emitting surface connects the first light-incident surface. The display panel is disposed adjacent to the first LGP. The transparent filling connects the display panel and the first light-emitting surface. The refractive index of the transparent filling is smaller than that of the first LGP and smaller than or equal to that of a surface material of the display panel. The first light source emits a first light beam into the first LGP through the first light-incident surface, and the first light beam is emitted from the first light-emitting surface and transmitted to the display panel through the transparent filling.

Abstract: An electronic reading device and an operating method for the same are disclosed. The electronic reading device includes a front light module and a reflective display. The front light module includes a white light source and a color light source. The color light source is selected from a group consisting of a red light source, a green light source and a blue light source. The reflective display is disposed on a side of the front light module.

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.
