Description

Declared as a utility model, the technical solution relates to the advertising industry and to the information technology industry, namely, to the technique in which the demonstrated material is attached to rotating structural elements.

A street video-roller display device is designed to demonstrate video information or static frames that dynamically replace each other - on screens installed on or near small objects.

The technical result of the application of the proposed technical solution is to increase the efficiency of using dynamic (with changing images) medium-sized street demonstration devices (screen area up to 10 square meters) - at any time of the day, in any ambient light.

Due to the fact that the proposed design combines two types of demonstration devices, a roller display and a video display (other names - video screen, video monitor) - we will give analogues and prototypes for each of them.

As ANALOGUES of the roller display are roller displays manufactured by domestic firms DiMedia, M2, Peak Media and others. Information about them can be found on the Internet on the websites of firms, respectively, at the following addresses: http://www.scrollers.ru/, http://scrollerm2.ru/, http://www.pik-media.ru/.

For the roller display as a prototype-1 - a roller display (scroller) of the DiMedia company of the standard "cityboard" with the dimensions of the demonstration field 2.7 × 3.7 m (height, width) was selected.

The design of the roller display includes: a box with a front wall, on which there is a demonstration window, protected by glass. Behind the demonstration window, posters and advertising frames made of rectangular pieces of flexible thin synthetic or paper strong translucent material are moved and stopped for demonstration, with images of advertising frames in the size of the demonstration window printed on their outer side. The basis of the design for moving and fixing posters in the demonstration window is made up of two horizontal metal shafts, upper and lower, to which the ends of the flexible tape formed by a number of posters connected in series are attached. Tape from posters, wound on one shaft - is wound from another shaft; the movement of the tape and its interference in the vertical plane are provided by the rotation of the shafts using electric motors. The stops for demonstration and the correct positioning of posters in the demonstration window are carried out either using positioning sensors or without sensors - using, for example, the DSS (digital scrolling system) system, digital roller rewinding system and positioning of advertising images. Scrolling modes of operation, automatic or manual, the direction and speed of rotation of the shafts, the time of the demonstration of frames - are set using a control board made on the basis of a microprocessor, which is programmed using a plug-in remote programmer. There is an internal illumination of posters with fluorescent lamps, which makes the advertising frame more visible and attractive in the dark.

As ANALOGUES of the video display, LED screens can be called. Information about them can be found on the Internet on the websites of manufacturers, for example, such as:

- "Display systems" - http://www.bigdisplay.ru/,

- "POLYLED" - http://www.polyled.ru/,

- "LED Video Screens" - http://www.led-screens.ru/,

- "S-Video" - http://www.led-world.ru/,

- "Ledoxx" - http://www.ledoxx.ru/,

- "ATV Outdoor Systems" - http://www.atvoutdoorsystems.ru.

Below are descriptions and typical designs of LED screens in street formats.

The principle of operation of LED screens is as follows. The element that forms the image on the LED screen is a semiconductor LED. The LEDs used have three primary colors - red, green and blue. Several LEDs of primary colors, structurally integrated into a single whole, make up a pixel, i.e. unit cell of the LED screen. By changing the intensity of the glow of each of the pixel LEDs, you can get almost the entire range of displayed color shades.

The number of screen pixels and their placement determine its resolution. The distance between the centers of adjacent pixels is called the pitch (pitch). The larger the step, the greater should be the viewing distance for a continuous perception of the image and to avoid the effect of discreteness.

Screens with a pixel pitch of 18-28 mm are considered medium-resolution screens and, as a rule, are used for outdoor applications. The typical size for such screens is 4 to 8 m in width with a viewing distance of 10 to 100 m. Screens with a pixel pitch of less than 18 mm are considered high-resolution screens and are used for both outdoor and indoor applications. The best examples of high-resolution screens have a 3-5 mm pixel. The screen size with a small pixel pitch can be small, 2-3 m wide.

Individual elementary pixels are structurally combined into modules. These modules make up the surface of the LED screen. The modules are mounted on a special mechanical design. The screen housing must be sealed - to protect against moisture, dust and insects. The screen design should allow quick replacement of failed individual screen modules.

To control the LED screen, a specialized controller is used, which is installed inside the screen body. This controller, in turn, is controlled by an external specialized computer. Its input ports connect standard video or computer signal sources. Signal sources can be, for example: video players such as CD-ROM, DVD, Flash and other types, TV tuners, video cameras and similar devices.

For the coordinated operation of all nodes of the LED screen, special software is required that automates the process of demonstrating video materials in accordance with a given sequence and cyclicity.

The dimensions of the visual part of the LED screen, consisting of modules, are limited in each specific application - the permissible weight of the structure and the maximum (peak) load of the screen power supply (when displaying a 100% white field).

The closest analogue, prototype-2, is a POLYLED LED screen with video image dimensions (384 × 256) cm, assembled from modules of the P10-o / d type. Information about them can be found on the Internet at: http://www.polvled.ru/item/41.

The size of the P10-o / d module is (96 × 64 × 15) cm and it consists of (96 × 64) pixels arranged in 1 cm increments. The screen can be composed of 16 (4 × 4) LED modules - 4 modules horizontally and 4 modules vertically of the screen.

The total physical resolution of the screen is (384 × 256) pixels, the virtual resolution will be (768 × 512) pixels (a virtual pixel is created by software from the LEDs of neighboring pixels).

The total weight of 16 modules with screen sizes (384 × 256) cm will be ~ 590 kg, and the power consumption of the screen is ~ 9.8 / 3.5 kW (maximum / average).

It should be noted that as a video display, you can use not only an LED screen, but also a screen assembled from plasma panels, or assembled from any other type of video module.

Common features of prototype 1, 2 and the claimed technical solution are a demonstration device with both an automatic cycle for displaying static frames on posters in the "roller display" mode and with automatic display of video images in the "video display" mode.

The differences of the proposed technical solutions from prototypes are:

- in the design of the video-roller display, two different types of demonstration devices are connected - a roller display and a video display;

- the operation of these devices is carried out alternately depending on the time of day in two different modes: "roller display" or "video display".

The purpose of the claimed utility model is to increase the efficiency of street dynamic demonstration devices at any time of the day.

Each individual device, video display or roller display, has its own advantages and disadvantages of displaying visual information - depending on the ambient light, which primarily depends on the time of day.

Video displays are effective in low ambient light - morning, evening, especially they are effective at night. In sunny weather, in bright conditions, the video image may practically disappear.

With roller displays, it's the other way around. The brighter the sun, the more colorful the roller frames. At low ambient light, they fade; either internal or external artificial illumination of roller posters is required.

The combination of a roller display and a video display in one design allows you to create a street dynamic demonstration video-roller device of the 24/7 class, i.e. a device that works efficiently all 24 hours a day and 7 days a week.

The essence of the claimed technical solution lies in the fact that the video-roller display device is combined, consisting of a roller display and a video display, which is performed on a standard basis of a roller display, but without a lighting system, instead of which a video display of a suitable size is installed, either assembled from LED modules, either from plasma panels or from video modules of any other type; moreover, the components of this combined device operate alternately, in two different modes: the roller display - in the daytime, and the video display - in the dark, while in the first mode the tape of posters, scrolling in an automatic cycle alternately in both directions, shows advertising frames on posters, in the second mode - the video display is turned on with the demonstration of video images, and the ribbon of posters stops in the extreme position, either freeing the demonstration window for the video display, or the extreme poster is I am transparent, without advertising image.

Outdoor video-roller display can be installed in crowded places, for example, in places of trade, sports facilities, airports, train stations, marinas and the like. It can also be used along roads and highways, on roadside buildings, pavilions and trade and food facilities, or next to them.

The design description of the claimed technical solution is illustrated by the schematically attached drawings in figure 1 (side view) and figure 2 (front view), where:

1 - display box;

2 - front wall;

3 - a protective glass of a demonstration window;

4 - a tape from posters;

5 - upper shaft with electric drive;

6 - lower shaft with electric drive;

7 - roller electronics;

8 - video display;

9 - video display electronics;

10 - back wall;

11 - support.

The video-roller display device consists of a metal box 1, front wall 2. On the front wall 2 there is a demonstration window protected by glass 3. Behind the demonstration window, advertising posters are connected and stopped for demonstration, connected in a single tape 4. The basis of the system for moving and fixing posters in the demonstration window are two horizontal metal shafts, the top 5 and bottom 6, equipped with electric drives. The ends of the tape of posters are attached to the shafts, which, being wound on one shaft, is wound from another shaft. The stops for demonstration and the correct positioning of posters in the demonstration window are carried out either using positioning sensors or without sensors - using, for example, the DSS (digital scrolling system) system, digital roller rewinding system and positioning of advertising images. The operation of the roller is controlled by the corresponding electronics 7. Opposite the demonstration window, immediately behind the ribbon of posters, there is a video display 8, the operation of which is controlled by the electronics 9. The entire structure is closed behind the rear wall 10. The video-roller display is installed using the support 11. The rear wall 10 can be used one static ad frame. The source of video signals for a video display can be any source of video information - a video player of any type, a TV tuner, a computer, a video camera, and others.

For sound accompaniment, if this is desirable and acceptable by the surrounding environment, the video-roller display can be supplemented with the corresponding external audio system.

The video-roller display device operates in two modes as follows.

In daylight hours the "roller display" mode is turned on. In an automatic cycle, a ribbon of posters, scrolling alternately in both directions, shows advertising frames on posters.

In the dark, the "video display" mode is activated, in which video images are displayed in a free window.

General control of the video-roller display can be carried out either manually by the commands of a service operator, or automatically from a real-time timer, the programming of which is focused on sunrise and sunset times in a given area, or from a wireless remote monitoring and control system (radio monitoring system) - with using networks such as GSM, GPRS, Wi-Fi or the like.
