Abstract

The utility model provides a novel LED display screen, which comprises a frame, at least one PCB (printed circuit board), a plurality of LED units and a display control device. The PCBs are arranged in the frame, the LED unit s are arranged on the PCBs in lattice manner so as to form LED pixel modules, the LED pixel modules include at least two modules, the LED pixel modules are sequentially arranged in a hollow square form from the central zone of the display screen to the outside, the spacings of LED unit points in a same one LED pixel module are the same, spacings of the LED unit points at the central zone of the display screen are smaller than that of LED unit points of the LED pixel modules at other zones, and the display control device is further disposed in the frame. The novel LED display screen is convenient to maintain and repair, and production cost is reduced and raw materials and energy resources are saved greatly while visual effect is guaranteed.

Description

A kind of New LED display screen

Technical field

The utility model relates to a kind of display device, relates in particular to a kind of LED display.

Background technology

Characteristics such as LED is a kind of solid-state semiconductor firmware that electric energy can be converted into visible light, and it has, and antidetonation is shock-resistant, speed of photoresponse is fast, power saving and life-span are long are widely used in various indoor, outdoor display screens.These display screens are located on the pcb board by the LED dot matrix and are formed, so be called LED display, it is to come the display screen of various information such as display text, picture, animation, video, video signal by the match light on and off and the color of incompatible control LED lamp body of hardware and software.If make information such as shown video, animation more fine and smooth, the LED dot spacing of setting is just more intensive, just needs more LED firmware.Usually display area all is bigger, and hangs on the body of wall, and the LED dot matrix is located on the same large tracts of land pcb board, if when central several LED damage, and difficulty relatively during maintenance maintenance.

And, investigation is found according to the study, people concentrate on the sight focus middle section of display screen usually when the various information of watching these display screens to show, sight focus concern is fewer comparatively speaking to the zone around the display screen, and the common area of these display screens is bigger, if the LED dot spacing all is arranged to equally size, will use more materials, cause the increase of cost, and large-area LED is more power consumption also, causes the waste of the energy.

The utility model content

Therefore, at the problems referred to above, the utility model provide a kind of for ease of maintenaince, reduce cost, save material and the New LED display screen of the energy.

For reaching above-mentioned purpose, the utility model is achieved through the following technical solutions: a kind of New LED display screen, comprise framework, at least one pcb board, some LED unit, display control unit, described each pcb board series arrangement is located in the framework, described LED unit dot matrix is located on the pcb board, form the LED picture element module, described LED picture element module is divided into two modules at least, described each LED picture element module outwards is " returning " font successively and arranges from the display screen central area, and the LED unit spot spacing in the same LED picture element module is identical, the LED unit spot spacing of LED picture element module that is positioned at the display screen central area also is provided with display control unit less than the LED unit spot spacing of other regional LED picture element module in the described framework.

Further, described display control unit comprises control module, gauge tap, control module, and described control module, gauge tap, control module electrically connect in proper order.

Further, the described framework back side and left and right sides wall all are provided with through hole.

By adopting preceding technical scheme, the beneficial effects of the utility model are: by LED unit dot matrix is located on a plurality of pcb boards, the maintenance maintenance that gets off for convenience detach, each pcb board is combined to form the LED picture element module simultaneously, and the LED picture element module is divided into a plurality of modules, the LED unit spot spacing of being located at the LED picture element module of display screen central area is provided with smaller, the LED unit spot spacing of other regional LED picture element modules of display screen is provided with bigger, simultaneously under the situation that guarantees the LED display visual effect, significantly reduced the LED unit on the LED display, thereby greatly reduce production cost, a large amount of simultaneously starting material and energy saved.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 be in the utility model pcb board and LED unit in conjunction with synoptic diagram.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

With reference to figure 1, the utility model embodiment discloses a kind of New LED display screen, comprise framework 1, at least one pcb board 2, some LED unit 3, display control unit, described each pcb board 2 series arrangement are located in the framework 1, described LED unit 3 dot matrix are located on the pcb board 2, form the LED picture element module, described LED picture element module is divided into two modules at least, described each LED picture element module outwards is " returning " font successively and arranges from the display screen central area, and the LED unit spot spacing in the same LED picture element module is identical, the LED unit spot spacing of LED picture element module that is positioned at the display screen central area also is provided with display control unit less than the LED unit spot spacing of other regional LED picture element module in the described framework 1.

The pcb board 2 that the utility model adopts polylith to be provided with LED unit 3 is assembled into the viewing area of display screen, when one or several LED unit 3 in the display screen damages, the maintenance of can getting off by the pcb board 2 that dismounting has LED unit 3 to damage makes things convenient for the maintenance maintenance of display screen.Described LED unit 3 combines the LED picture element module that forms and is divided into four pack modules with described pcb board 2, be respectively module 21, module 22, module 23, module 24, described each module outwards is " returning " font successively and arranges from the display screen central area, and the LED unit spot spacing in the same module is identical, described module 21, module 22, module 23, the area of module 24 respectively accounts for 1/4th of the whole area of display screen, and from LED display central area outward direction, described module 21, module 22, module 23, LED unit spot spacing ration in the module 24 is: 1: 2: 3: 4.By method to set up with upper module, LED display of the present utility model can save LED unit and drive IC each 45%, not only saved starting material, reduced production costs, also saved the energy effectively.

Among the utility model embodiment, described display control unit is used for controlling the light on and off and the color change of LED unit, and by matching with software, make LED display can show information such as various literal, picture, video, animation, this display control unit comprises control module, gauge tap, control module, and described control module, gauge tap, control module electrically connect in proper order.The principle of work of this display control unit is: by with the matching of software, import predefined control program into control module, when satisfying the condition that presets, control module is according to the control program that presets, the start-up control switch, simultaneously with default LED control signal, send to control module by signal wire, control module receives the LED control signal drive controlling LED unit from control module, and according to the LED control signal of each signal wire transmits, the LED unit of drive controlling varying number, make each LED unit can realize that different brightness change, and make to mutually combine between each LED unit and be the variation of different colours, thereby make display screen show various literal, picture, video, information such as animation.
