Problems solved by technology

[0002] In the prior art, the double-sided display device is the lamination of two display devices, and for the transparent display device, due to its transparent characteristics, when the double-sided display is realized, the images displayed on the two sides will interfere with each other. The display effect is extremely poor, so there is no transparent display device that can realize double-sided display

Embodiment Construction

[0028] In the double-sided display device and electronic equipment of the embodiment of the present invention, a blocking module is set between the optical waveguide display modules capable of realizing transparent display, and the blocking module can block each optical waveguide display module from displaying in the display state. The linearly polarized light irradiated on the surface of the blocking module after being scattered by the liquid crystal layer can avoid mutual interference between the optical waveguide display modules. For natural light, the components with the first polarization direction are also blocked, while the components with the second polarization direction perpendicular to the first polarization direction can pass through and become background light to realize transparent display.

Abstract

The invention discloses a double-sided display device and electronic equipment. The double-sided display device comprises a first optical waveguide display module, a second optical waveguide display module, a light source and a blocking module, wherein the first optical waveguide display module is provided with a first liquid crystal layer which is in a scattering state under the action of an electric field; the second optical waveguide display module is provided with a second liquid crystal layer which is in a scattering state under the action of the electric field, and is jointed with the first optical waveguide display module; the light source is used for generating linearly polarized light which has a first polarization direction and is output to the first optical waveguide display module and the second optical waveguide display module; the blocking module is arranged between the first optical waveguide display module and the second optical waveguide display module and is used for blocking the transmission of the linearly polarized light; the blocking module shows a characteristic of semi-reflecting and semi-transmitting for natural light. After the double-sided display device is used, double-sided transparent display with less interference is realized.

Description

technical field [0001] The invention relates to a double-sided display technology, in particular to a double-sided transparent display device and electronic equipment with less mutual interference. Background technique [0002] In the prior art, the double-sided display device is the lamination of two display devices, but for the transparent display device, due to its transparent characteristics, when the double-sided display is realized, the images displayed on the two sides will interfere with each other. The display effect is extremely poor, so there is no transparent display device that can realize double-sided display at present. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a double-sided display device and electronic equipment, so as to realize double-sided transparent display with less interference. [0004] To achieve the above purpose, an embodiment of the present invention provides a double-sided displa...
