[0041] Such as figure 2 , when sunlight irradiates on the rotating polarizer, when no driving voltage is applied to the 103 liquid crystal panel, the device presents a transparent state, such as the white area in the 106 projection, the light passes through the 102 first polarizer, 103 liquid crystal panel, The 104 second polarizer reaches the 105 plane mirror, and is reflected by the 105 plane mirror, and the reflected light passes through the 104 second polarizer, the 103 liquid crystal panel, and the 102 first polarizer to reach the designated area of ​​the wall in sequence. When no driving voltage is applied to the 103 liquid crystal panel, the light loss reflected by the 105 plane mirror is the least.

[0042] When the maximum driving voltage is applied to all pixels of the 103 liquid crystal panel, the device presents a completely opaque state, such as the black area in the projection of 106, the light passes through the first polarizer of 102, the liquid crystal panel ...

[0046] Such as image 3 , The rotating polarizing device applies different voltages to all pixels of the entire 103 liquid crystal panels to display static and dynamic pictures and text content.

[0047]The picture deformation processing unit deforms the static and dynamic pictures and text content to be displayed on the 103 LCD panel at different times of the day, so that the picture content reflected on the wall is close to the real shape.

[0048] The directional device directionally reflects the static and dynamic pictures and text content to be displayed to the designated area of ​​the shady wall.

Abstract

A directional rotation polarized reflection advertisement improving device adjusts the transparency of each pixel point by applying different voltages to each pixel of a liquid crystal panel, so as toadjust the sunlight intensity of light reflected by each pixel; by the application of a driving voltage to the liquid crystal panel, the liquid crystal panel displays static and dynamic advertisements and textual contents, and the static and dynamic advertisements and textual contents to be displayed are directionally reflected to a specified area of a shady wall through a directional device. Thedirectional rotation polarized reflection advertisement improving device utilizes sunlight as a light source, avoids energy consumption and waste, saves energy and is environmentally friendly. The directional rotation polarized reflection advertisement improving device can well display various static and dynamic advertisements during the daytime. The structure is simple, a method is novel, a newvisual impact can be generated, and the device is easy to implement and promote. The invention also provides a directional rotation polarized reflection advertisement improving method.

Description

technical field [0001] The invention relates to the technical field of outdoor advertising projection devices, in particular to an improved device for directional rotating polarized reflection advertising and a control method thereof. Background technique [0002] Projection advertising uses a high-power projection device, uses the principle of optical projection, and uses a high-brightness light source to project the full-color advertising content on the film onto the outer wall of a high-rise building, forming an outdoor advertisement with great visual impact at night. [0003] Projection technology can be applied in outdoor environments: building facades, public buildings, stadiums (at night). [0004] Due to the novelty of projection advertising, consumers will pay more attention to it. When consumers look at the exquisite and dynamic projection screen, the product has already entered the minds of followers unconsciously. For outdoor advertising, The advantages of dynam...
