Problems solved by technology

[0003] However, the current joint display screens are all staggered and supplemented structures. The above structure has the following defects: 1. There is a large distance between the upper and lower holographic fans, and the lower holographic fans may be blocked by the upper holographic fans. , the viewing angle is small, and the overall viewing distance of the joint display screen is limited; 2. The overlapping part of the upper and lower holographic fans along the vertical direction will produce a "horn" phenomenon, that is, an arc that is whitened due to excessive brightness

Embodiment Construction

[0023] It is particularly pointed out that the terms "first", "second", and "third" in the present invention are only used for descriptive purposes, and cannot be interpreted as indicating or implying relative importance or implicitly indicating the indicated technical features. quantity. Thus, features defined as "first", "second", and "third" may explicitly or implicitly include at least one of these features. In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined. All directional indications (such as up, down, left, right, front, back, etc.) When a specific posture changes, the directional indication changes accordingly.

[0024] Below by embodiment technical solution of the present invention is described further:

[0025] The invention provides a holographic fan combined with a display screen, such as figure 1 As shown, the joint display screen includes: a plurality of holographic fan...

Abstract

The invention discloses a holographic fan combined display screen. The holographic cooling system comprises a plurality of holographic fans (100), the holographic fans (100) are arranged in a rectangular array mode. The holographic fan includes: a fan blade assembly (1), a control mechanism (2) and a supporting assembly (3). The control mechanism (2) is fixed on the supporting assembly (3); wherein the fan blade assembly (1) is rotatably arranged on the control mechanism (2); the fan blade assembly (1) comprises a plurality of blades (12) arranged in a 360-degree circumferential array mode. The difference of the rotating angles of the blades (12) of every two adjacent holographic fans (100) is 1/2 of the included angle theta of the blades, and the horizontal center distance between every two adjacent holographic fans (100) is larger than the length of the corresponding blade (12) and smaller than two times of the length of the corresponding blade (12). According to the holographic fancombined display screen, the effect of combined display of multiple holographic fans can be achieved, the visual range is wide, the watching distance is long, and the ox horn phenomenon can be avoided.

Description

technical field [0001] The invention relates to a combined display screen, in particular to a holographic fan combined display screen. Background technique [0002] The 3D holographic fan screen is a new type of advertising display device. Its main advantages are low energy consumption, cool effect, full sense of technology, and the display effect is higher than that of traditional advertising machines. Due to the limited size of the holographic fan, in order to realize a large-screen display, the existing display screen uses a plurality of holographic fans for combined display. [0003] However, the current joint display screens are all staggered and supplemented structures. The above structure has the following defects: 1. There is a large distance between the upper and lower holographic fans, and the lower holographic fans may be blocked by the upper holographic fans. , the viewing angle is small, and the overall viewing distance of the joint display screen is limited; 2...
