Description

Technical Field

[0001] The utility model relates to the technical field of sunlight screens, in particular to a low-power sunlight screen display terminal. Background Art

[0002] The reflective sunlight screen is a display device designed specifically for outdoor environments. Its unique working principle and structure enable it to efficiently utilize ambient light or natural light for display without the need for an additional backlight source.

[0003] When installing a conventional sun screen, a stable bracket needs to be installed at the bottom. The bracket needs to be driven into the ground. The ground needs to be broken and anchor bolts need to be driven in. Then the bracket and anchor bolts are connected. This means that when the old screen is expanded with a new sun screen, the ground needs to be processed again, and then a new bracket, i.e., a supporting structure, is installed. Then, a new expanded sun screen is installed. The expansion cost is high, and the expansion of the sun screen is more troublesome. Utility Model Content

[0005] Therefore, one purpose of the present invention is to provide a low-power sunlight screen display terminal to solve the problems mentioned in the background technology and overcome the deficiencies in the prior art.

[0006] In order to achieve the above-mentioned purpose, an embodiment of one aspect of the utility model provides a low-power sunlight screen display terminal, including a main screen, a base, a fixing frame, a connecting plate, and a column, wherein the bottom of the main screen is fixedly connected to the base, the front, bottom and back of the base are fixedly connected to the fixing frame, the bottom of the fixing frame is fixedly connected to the connecting plate, and the middle of the bottom surface of the connecting plate is fixedly connected to the column;

The liquid crystal layer is located below the reflective layer and is the key part of controlling the propagation path of light. The liquid crystal molecules can change their arrangement direction by applying an electric field, thereby changing the propagation path of light. The transparent conductive layer is located below the liquid crystal layer and is used to apply an electric field to control the arrangement direction of the liquid crystal molecules. By controlling the change of the electric field, the arrangement direction of the liquid crystal molecules can be precisely controlled, and then the propagation path of light can be controlled, thereby forming various images and texts on the screen. Since the reflective sunlight screen uses ambient light or natural light for display, no additional backlight source is required, and it has the advantages of energy saving, environmental protection and low power consumption.

The core advantage of this device is: the main screen of the sunlight screen is easy to expand, and no additional support structure is required for expansion. Instead, the first joint is installed at the four corners of the main screen and the screen to be expanded, and the second joint is installed on the back of the main screen and the screen to be expanded. The connecting beam is inserted in the first joint and the second joint, and locked with bolts and nuts, so as to realize the rapid connection between the main screen and the expansion screen, and the rapid expansion of the main screen is realized. No complex support structure such as support column is required, which greatly simplifies the installation steps. The first joints at the four corners and the second joints on the back cooperate with the design of the connecting beam to provide multi-point support, ensuring the stability of the connection between the main screen and the expansion screen. No additional support structure is required when the expansion screen is expanded, and there is no need to deal with the ground installation support column. It only needs to be docked with the original main screen, which reduces the material cost and installation cost.
