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.

Description

technical field [0001] The present invention relates to an optical device, in particular to a display device. Background technique [0002] For electrophoretic display panels, liquid crystal display panels and other panels that do not emit light by themselves, they are often matched with light source modules so that the display device can be viewed in an environment with insufficient light. For the transmissive liquid crystal display panel, a backlight module is often used to place behind the transmissive liquid crystal display panel to provide sufficient illumination for the transmissive liquid crystal display panel. On the other hand, for a reflective electrophoretic display panel (such as electronic paper) or a reflective liquid crystal display panel, a front light module is usually arranged in front of the panel, which can also provide sufficient illumination for the panel. [0003] To provide lighting outside the non-display area with the current existing technology, a...
