Description

A kind of LED display display unit

Technical field

The utility model relates to the display screen field, relates in particular to a kind of LED display display unit.

Background technology

LED display has obtained using very widely, and in some special application scenarios, LED display requires to have penetrating structure, and its advantage is: (1) is block vision not, can see the scenery of LED screen front and back; (2) keep certain daylighting effect, can satisfy when particularly being used on glass curtain wall or the show window indoor daylighting needs; (3) reduce to greatest extent using the influence of on-the-spot whole decoration design; (4) have certain artistic effect, when the stage performance is used, can reach and only see that image loses the fancy effect of screen especially.Because above characteristics, the LED display of open type is subjected to the welcome of some particular application especially, for example on the airport, hotel, glass curtain wall building, conference and exhibition center, stage, shopper window etc., its result of use be conventional tank formula structure LED display can not match in excellence or beauty.The design of open type LED display should be considered penetrating rate, considered pixel density again, and under same structural design condition, picture element density is more big, and penetrating rate is just more little, and translucent effect is just more poor.Below be the relation of the screen pixels density of several typical pel spacings and correspondence:

Pel spacing P(pixel pitch)	Picture element density R (resolution)
		40mm	625pixel/㎡
25mm	1,600pixel/㎡
		20mm	2,500pixel/㎡
16mm	3,906pixel/㎡
		10mm	10,000pixel/㎡
8mm	15,625pixel/㎡
		7mm	20,408pixel/㎡

6mm	27,777pixel/㎡
		5mm	40,000pixel/㎡

* picture element density computing formula: R=(1000mm*1000mm)/(P*P)

By last table and formula as seen, along with reducing of pel spacing, picture element density is geometric series and rises, significantly, below the 10mm pel spacing, every minimizings of pel spacing 1mm, the numerical value of picture element density rising is considerable.
