Description
Technical field
The present invention relates to LED screen fields, and in particular to a kind of LED display and its adjustment method.
Background technique
LED display is collection photoelectron technology, microelectric technique, the high-tech that computer technology and video technique are integrated
Product, because the advantages such as itself brightness height, small power consumption, enlargement, impact resistance have socially obtained universal application.And in recent years
Come, as the price of LED display gradually decreases, the raising of color and bandwagon effect, so that the application places of LED display are got over
Come more extensive.
LED display is a comprehensive stronger product.From production, installation, debugging, after sale, there are many rings for centre
Section.Each link has the space of promotion and optimization.
The material of existing LED unit plate housing assembly is ABS engineering plastics.Of different sizes according to cell board, thickness is about
For 1.5-2.5mm.In ABS, B refers to the characteristic of high resiliency and toughness, so, when with a thickness of 1.5-2.5mm, shell
There is certain deformation, this is the result that we are not intended in LED unit plate housing assembly.Usual way is,
It adjusts in structure, does horizontal, vertical staggered reinforcing rib in the plane to improve intensity.
But LED unit plate can generate heat during the work time.In summer, temperature can reach six or seven ten degree, easily cause change
Shape, on the market, most cell board length-width ratios are 3:2,4:3,5:4, these ratios, close to square.From structure, more become
It is more secured in square.For from size, long edge size is mostly 120mm, 160mm, 180mm, 240mm.It is limited by existing
The limitation of material, structure is difficult to make large scale, and ratio is the LED unit plate of 16:9.
Large-sized cell board is made under the conditions of existing, generally use metal cabinet realization: for LED lamp bead spacing
Greater than 2.0mm, cabinet is welded with the technique connect using profile；Less than 2.0mm, cabinet is processed using die casting aluminium extra bus bed, milling machine
Mode, then lesser cell board is fixed on metal cabinet, form a biggish unit, but in this way there are one
Assemble the biggish problem of cost.
Currently, most computer monitors, notebook, the ratio of all television sets are all 16:9, this is a symbol
Close a golden ratio of human eye vision.Matched video material, picture materials, PPT etc., it is all very universal.Therefore,
LED screen will be made into 16:9, the adaptation of ability The Gift of Being the Best You Can Be.However, the screen that current cell board will be combined into 16:9 is not
So flexibly, we specifically analyze below；
Firstly, for example we come by the cell board of 4:3.As shown in Figure 1, to obtain the screen of a 16:9, only 3
The column of row 4,6 rows 8 column, 9 rows 12 column etc.., can satisfy requirement, it can thus be seen that the minimum span of horizontal direction is 4 pieces of lists
The width of first plate, vertical direction are the height of 3 module unit plates.For the experience in construction, construction site can be made very
Meet expected width, the screen difficulty of height is biggish；
Secondly, from debugging with after sale from the aspects of, LED unit plate manufacturer, control system manufacturer, retail trader, engineering
Quotient is numerous, and technical level, service quality are irregular.Installation and debugging are complicated, and after-sales service is difficult, greatly compromise user's
Interests also restrict the development of entire field of LED display.
Nowadays after the control card more renewed by industry technology reason LED display, commissioning staff is needed to use computer again
Secondary transmission control card data, just can guarantee LED display normal use, this makes maintenance process long, wants to maintenance personnel's technology
It asks high, and then maintenance cost is caused to increase；
Current LED display synchronous playing system according to signal trend be broadly divided into computer computer, be played simultaneously device,
Signal receiver three parts, computer and player are two independent equipment, between communication still need to pass by video cables
Defeated signal, there are the following problems: 1, the screen of display screen becomes greatly, and therefore, single video interface has been unable to satisfy display
The resolution ratio of screen, but because of the limitation of video card interface quantity, the complete of display screen picture can only be completed by external splicing equipment
It has been shown that, but such splicing equipment volume is big and expensive, can not promote on a large scale, realizes that suitable automatic Adjustment Technique will more
Add the development for being applicable in LED display industry；2, usually used video interface has DVI, HDMI etc., is usually used in desktop-use graphics chip
On, moreover, display screen can generate picture tearing, therefore, display screen when playing fast video because of integrated graphics card performance reason
Broadcasting also rely on independent display card, cause cost to increase, also, the volume of desktop computer is larger, in terms of portability experience compared with
Difference.
