Problems solved by technology

Especially along the expressway, a large number of variable information boards are installed and run around the clock, which consumes a lot of power, resulting in a large energy loss; in addition, the viewing distance of LED variable information boards decreases with the increase of ambient brightness
The main reason for the large energy loss caused by the current LED variable information board is: when displaying information content, the corresponding LED light-emitting device operates continuously

Embodiment Construction

[0019] The present invention will be further described below in conjunction with drawings and embodiments.

[0020] A non-self-illuminating variable display device, including a panel 1, the display device also includes a plurality of color squares 2, a square rotation mechanism corresponding to the color squares 2 and a control system 3, and the color squares 2 pass through the square The rotating mechanism is rotatable and regularly installed on the upper surface of the panel 1, the control input of the block rotating mechanism is connected to the control output of the control system 3, and the four sides of the colored blocks are coated with paints of different colors. The rotation angle of the colored square is 90 degrees.

[0021] According to the principle of dot matrix display, each color square 2 is used as a pixel in the dot matrix, and each color square 2 can display characters or images according to a certain logical combination according to the background color and ...

Abstract

A non-self-luminous variable display device comprises a panel, and the display device also comprises a plurality of colored cubes, cube rotating mechanisms corresponding to the colored cubes one by one and a control system, wherein the colored cubes are regularly installed on the upper surface of the panel in a rotating way through the cube rotating mechanisms, a control input end of each cube rotating mechanism is connected with a control output end of the control system, and four side surfaces of each colored cubes are respectively coated with paint with different colors. Due to adopting the non-self-luminous variable display device, the electric power can be maximally saved, the carbon emission can be reduced, and the vision distance can be remarkably improved.

Description

technical field [0001] The invention relates to the technical field of control, in particular to a variable information board. Background technique [0002] The variable display device can realize the dynamic display and release of information, and is widely used in the fields of roads, traffic, advertisements and the like. The variable information board is the most typical application of the variable display device, especially in the field of roads and traffic. It is usually installed on road junctions, bridges, tunnels, elevated roads, expressways and other facilities to establish eye-catching traffic guidance information boards. It is used to indicate information such as traffic conditions, road conditions and occasional events ahead of the driver. [0003] At present, variable display devices represented by variable information boards and variable sign boards all use LED light-emitting devices as the basic display unit and have graphic and text display functions, which ...
