The drawings of the specification, forming a part of the disclosure, are used to provide further understanding of the disclosure. The schematic embodiments and illustrations of the disclosure are used to explain the disclosure, and do not form improper limits to the disclosure. In the drawings:
Wherein, the drawings include the following drawing marks:
1, single-faced display device; 2, viewer; 10, lamp bead; 20, lamp bead mounting plate; 21, second reflecting surface; 30, lamp bead shading face mask; 31, light emergence hole; 32, first reflecting surface; 40, transparent block; 41, light emergence face; 50, light path; and 100, display device.
It is important to note that some embodiments of the disclosure and the characteristics in some embodiments can be combined under the condition of no conflicts. The disclosure will be illustrated below with reference to the drawings and some embodiments in detail.
It shall be pointed out that the following detailed illustrations are examples and intended to provide further illustrations for the disclosure. Unless otherwise noted, all technical and scientific terms used herein have the same meanings usually understood by those skilled in the art within which the disclosure falls.
In order to facilitate descriptions, space relative terms can be used here. For instance, terms ‘over’, ‘above’, ‘on an upper surface’, ‘upper’ and the like are used to describe a space position relationship between a device or characteristic and other devices or characteristics shown in the figure. It will be appreciated that the space relative terms are intended to comprise different locations, except locations of the device described in the figure, in usage or operation. For instance, if the device in the figure is inverted, a device described as a device above other devices or constructions or over other devices or constructions will be located below other devices or constructions or under other devices or constructions thereafter. Consequently, the term ‘above’ may include two locations namely ‘above’ and ‘below’. The device may be positioned in other different modes (rotated for 90 degrees or located at other locations), and space relative descriptions used here are correspondingly explained.
Now, implementations according to the disclosure will be described in more detail with reference to the drawings. However, these implementations can be implemented in various different forms, and shall not be interpreted as implementations only limited to be elaborated here. It will be appreciated that provision of these implementations is intended to make the disclosure thoroughly and completely disclosed, and concepts of these implementations are fully transferred to those skilled in the art. In the drawings, in order to make it clear, the thickness of a layer and the thickness of a region are increased, and the same device is represented by the same drawing mark, such that descriptions thereof will be omitted.
