Eòlas bunaiteach air taisbeanadh LED

One.Classification de scrionaichean taisbeanaidh LED

A-staighTaisbeanadh LEDFaodar a chleachdadh ann an àrainneachd a-staigh. Tha soilleireachd meadhanach aig an seòrsa scrion taisbeanaidh seo, ceàrn mòr seallaidh, measgachadh dath dlùth, cuideam aotrom agus dùmhlachd àrd. Tha e freagarrach airson sùil gheur.

Outdoor Taisbeanadh LED Outdoor Taisbeanadh LED is used in outdoor environment, such display screen has high brightness, long color mixing distance, high protection level, strong waterproof and anti-ULTRAVIOLET ability, suitable for remote viewing.

Dath Taisbeanaidh aon-dathTaisbeanadh LED Single-color Taisbeanadh LED consists of LED lights of one color and can only display a single color, such as red, green, orange, etc.

Dual-color Taisbeanadh LED Dual-color Taisbeanadh LED consists of red and green LED lights. The 256-level grayscale dual-color display can display 65,536 colors (dual-color display can display red, green and yellow).

Full color Taisbeanadh LED Full color Taisbeanadh LED consists of red, green and blue LED lights. It can display white balance and 16,777,216 colors.

Display function Text Taisbeanadh LED (asynchronous screen) text Taisbeanadh LED can display text, graphics and pictures and other information content.Networkable offline display.

Video Taisbeanadh LED (synchroscreen) Video Taisbeanadh LED can display all kinds of information in real time and synchronously, such as 2d or 3D animation, video recording, TV, video disc, live scene and other video information content.

Two.The basic structure of Taisbeanadh LED screen

1. Sgrion asyncronach:

San fharsaingeachd, tha e air a dhèanamh suas de bhòrd aonad taisbeanaidh (modal), cairt sgrion stiall, atharrachadh solar cumhachd agus bòrd HUB (roghainneil). Ceangail ris a ’choimpiutair tro loidhne port sreathach, atharraich an teacsa taisbeanaidh, agus an uairsin faodaidh tu an coimpiutair airson obrachadh.

2. Synchroscreen:

Synchronous screen system is relatively complex, the system can be large or small, generally by computer, DVI graphics card, data sending card, synchronous data receiving card, HUB board, network cable, Taisbeanadh LED screen and other components.The system always needs an online computer to work and display the images and words on the computer on the large LED screen.

Three.Noun concept involved in Taisbeanadh LED

1. Pixel LED:

Is e seo an aonad dealbh as lugha deTaisbeanadh LED.Commonly ris an canar "dotagan" no "pixel".

2. Modal Taisbeanaidh LED:

The smallest unit of an Taisbeanadh LED consisting of several display pixels that are structurally independent.

· Bidh scrion a-staigh a ’cleachdadh modal taisbeanaidh 8x8, is e sin, tha 64 piogsail anns gach modal taisbeanaidh

· Bidh an scrion a-muigh a ’cleachdadh grìogag lampa singilte, a tha mar as trice air a dhèanamh suas le grìogagan lampa 1-3 de na h-aon dathan no diofar dathan gus puing picteal den mhodal a chruthachadh.

3. Modal Taisbeanaidh LED:

An independent unit consisting of an Taisbeanadh LED, as determined by the circuit and installation structure, and having display functions.To put it simply, for the convenience of assembly and display, semi-finished products from the factory are usually provided in the form of display modules, which combine multiple display modules and display drivers together.Interior screen commonly known as "unit board";Outdoor screen commonly known as "module", and then a number of modules plus chassis, fans, power supply and other structures together into a "box", mostly used for large full color screen.

· Mar as trice tha bòrd an aonaid sgrion a-staigh 64x32 (64 colbhan agus 32 sreathan, air a dhèanamh suas de 32 modalan) agus 64x16

(64 colbhan, 16 sreathan, air a dhèanamh suas de 16 modalan), msaa. Tha am figear a leanas a ’sealltainn bòrd aonad 64x16:

Mar as trice tha measgachadh de 64X32, 32x32, 32x16, 16x16 agus 16x8 aig modalan sgrion a-muigh.

Gu h-àrd tha modal sgrion a-muigh 16x8 (2 dearg). Structar dìon-uisge air a chleachdadh anns a ’bhlàr a-muigh, chì sinn an t-slige plastaig, is e an taobh cheart de ghraf plèana an structair gu lèir: cuir air a’ bhòrd taisbeanaidh bead aotrom, is e air ais air cuairt draibhear taisbeanaidh, a bheil an structar fuarachaidh seo, cuideachd gu leòr ri dhèanamh airson a ’bhòrd taisbeanaidh agus cuairteachadh draibhear taisbeanaidh air pìos de bhòrd cuairteachaidh, ailtireachd iomlan an fhigear a chì sinn an eadar-dhealachadh eadar an dà rud a leanas. tha pannal agus an t-slige cùil mar shlige còmhdach plastaig. Tha tuill anns a ’phannal aghaidh a rèir suidheachadh grìogag an lampa gus am bi grìogag an lampa ag aoidion. Tha tuill sgriubha no colbhan magnetach air an t-slige chùil airson an stàladh gus am bi am modal furasta a chruinneachadh. Tha aghaidh a ’mhodal air a lìonadh le inneal dìon-uisge sònraichte airson scrion taisbeanaidh.
