Abstract

The utility model relates to a novel LED screen, which is a display screen for outdoors advertising promotion, displaying relative graphic and text and video information. Common used LED display screen is of either bad heat dissipating or not good screen display effect because of sparse arrangement of dot matrix module formed by each LED lamp, moreover, large flat display screen is not convenient for installing, detaching and repairing, and the angle of the screen visual angle is not adjustable after the screen is mounted, being shading and not penetrating. In order to overcome the above defects, the utility model adopts that each unit board is arranged as slim sheet, being covered with the unit board protection housing and mounted, each unit board protection housing is parallel arranged horizontally or vertically to form a structure like a window blind, and the two ends of the unit board protection housing can be fixed on the outer frame of the screen by a device with rotatable shaft. The utility model has the advantages of convenient for installing, detaching and repairing, good capability of ventilating and heat dissipating, adjustable angle of screen visual angle, random combination of unit board into flat, curved surface, or irregular structure as the requirement of project, good penetrating and lighting effect of screen, etc.

Description

A kind of new LED screen

Technical field

The utility model relates to a kind of new LED screen, is a kind ofly to be used for indoor outer advertising, to show the display screen that relevant information is used.

Technical background

In the advanced information society, demonstration product and technology as people's one machine information visual communication medium are developed rapidly, lattice module or pixel cell that LED display utilizes light emitting diode to constitute are formed, in order to display pattern, Word message, and characteristics such as, cost performance height strong with its reliability height, long service life, adaptive capacity to environment, shooting up is the main product of flat pannel display, has obtained using widely in field of information display.

Yet conventional LED display is on the lighttight slab construction of bulk, utilizing light emitting diode is that LED forms a pixel, each pixel be combined into certain interval arranged have pattern, the cell board of Word message or casing, the cell board of varying number or casing piece together a monoblock display screen of different area again.

Because the light emitting pixel of display screen all is arranged on the lighttight bulk slab construction, display screen is come with some shortcomings when the application of some occasion, such as, glass of building within the walls or outside the visual effect that large-area conventional LED display can influence personnel in the daylighting of interior of building and the building is installed, or the influence visual effect of inwardly watching by the buildings outside; The LED lamp is installed on a monoblock slab construction, if lattice module or pixel cell that each LED lamp constitutes are too intensive, to produce very big heat when the LED lamp is worked so, and the heat dispersion of the light tight flat board of bulk is poor, if the LED lamp works long hours, each parts will bear bigger load, if the lattice module or the pixel cell of LED lamp formation are arranged the sparse good screen display effect that do not reach again; And the dull and stereotyped giant-screen angular field of view of forming of a monoblock is little, and angle can not be adjusted and the bulk flat board is formed display screen installation, dismounting and maintenance are all very inconvenient.

Summary of the invention

The novel technical matters that will solve of this use be how to solve lattice module that conventional display screen heat dispersion difference and each LED lamp constitute or pixel cell arrange sparse do not reach between the good screen display effect conflict and bulk flat pannel display screen is not easy to installation, dismounting and maintenance and bulk flat pannel display screen and installs that back screen viewing angle angle can not be adjusted, the impermeable deficiency of shading.

For solving the problems of the technologies described above, the utility model provides a kind of new LED screen, every module unit plate is arranged to the elongate strip thin slice, every module unit plate table planar horizontal is placed and is wrapped up by a flat cell plate guard shield, on cell board, be provided with a plurality of LED luminous points every the certain intervals arranged, be the light emitting pixel matrix, the LED luminous point is installed on the table plane of rectangular cell board, and become horizontal setting with the table plane of cell board, wrap up with a flat shell outside at cell board, housing is established an open slot, makes the LED light emitting source stretch out the opening of parcel cell board shell.After each cell board is wrapped in the cell board guard shield and installs, with each cell board guard shield level or vertically be arranged in parallel, composition resembles the venetian blind type structure, and cell board guard shield two ends are fixed on the framework of screen by the device that has rotatable rotating shaft.

On the strip element plate, be provided with luminous point, power supply, control chip and power lead that is connected with control chip and control line.Be provided with a draw-in groove that is used for the horizontal positioned stripe board in the guard shield of parcel stripe board, and stripe board can be placed in this guard shield inside stably, on guard shield, have an open slot that is slightly larger than the luminous point outline diameter, make luminous point expose stripe board guard shield table plane.The device of rotating shaft can adopt a bearing, and by the rotation of driven by motor bearing.

The beneficial effects of the utility model are: because the bulk panel display screen is being divided into each elongate strip cell board, and also can play the whole structure that the bulk panel display screen shows by interconnecting of each elongate strip cell board, such structure is provided with to be used flexibly, is convenient to install, dismantles and maintenance; Screen body ventilation and heat performance is good, and the long-term work that helps LED and power supply is used; The screen body installs back screen viewing angle angle and can adjust by the rotatable turning gear of controlling the guard shield two ends of wrapping up the elongate strip cell board; Because each cell board guard shield level or vertically be arranged in parallel, to form and resemble the venetian blind type structure, such screen entire combination can make the penetrating daylighting of screen effective.
