Description
Technical field
The present invention relates to display field more particularly to a kind of LED display installation methods of high-precision high-flatness.
Background technique
LED display flatness concept of the invention refers to the flatness of the line direction (also referred to as horizontal direction) of unit module
With the flatness of the column direction (also referred to as vertical or vertical direction) of unit module.With the continuous maturation in LED display market, skill
Art is constantly updated, and the market demand is increasing.Since LED display belongs to giant mechanical and electrical equipment, installation at the scene, visitor are needed
Family is all very high to longitudinal flatness of LED display and lateral flatness requirement.But nearly two during the last ten years, rectangle LED display
The LED display flatness that existing installation procedure is installed is constantly present zigzag fashion, is difficult to be entirely satisfactory client.
Existing rectangle LED display installation procedure is as follows:
Step 1: the frame of ground spliced fixed LED display and installation are used for the vertical bar of installation unit module at the scene.
Step 2: being measured with tape measure 2 diagonal lines.
Step 3: according to the 2 of measurement catercorner lengths as a result, carrying out size tune to the frame of the frame of LED display
It is whole, size adjusting in place after, the frame of LED display is fixed with fastener.
Step 4: installing the frame of LED display on metope or mounting bracket frame.
Step 5: using ceiling hammer technology or laser leveler technology to the frame deviation of mounted LED display
Size is adjusted.
Step 6: the unit module (and power supply and control card etc.) of installation LED display.
The LED display flatness being installed using existing installation procedure and technology is all poor, and viewing LED is aobvious
It can find that unit module zigzag fashion can all occur in line direction and column direction when display screen (facing LED display), especially arrange
Direction will appear apparent zigzag fashion, and out-of-flatness, zigzag fashion is in >=± 1mm -≤± 10-20mm, serious zigzag fashion
≥±20mm。
It is made of due to LED display the unit module splicing of one piece, one piece, if two adjacent unit modules
There is small deviation in splicing, multiple unit module splicings are completed just to have very big deviation.Such as: small deviation
For 0.8mm, 10 module unit modules, which are stitched together, will the deviation of 7.2mm, and 20 module unit modules are stitched together and will have
The deviation of 14.4mm or so.
The reason of causing such case is:
The frame of the 4th mounted LED display of step has in the flatness and horizontal line of line direction (also referred to as horizontal direction)
Deviation；The flatness and vertical line of the column direction (also referred to as vertical or vertical direction) of unit module have deviation.
Deviation timing is carried out in the 5th step, is carried out at the construction field (site) partially using ceiling hammer technology or laser leveler technology
Poor timing does not reach the requirement of correction.The reason is that both technologies are all defective: ceiling hammer technology determines that a point needs
It wants several hours ceiling hammers that can just settle out, is accurately positioned.The duration of construction site is all very nervous, basic without more than needed
Time.Laser leveler technology, since construction site ground is substantially uneven, the horizontal foresight of laser leveler will be looked for
It puts down extremely difficult；Therefore all it is difficult to reach the requirement for installing high-precision flatness LED display in a short time.It is watched with eyes
When due to lacking short distance reference material, often do not see deviation.
LED display industry Nei Ge company all claims: the error of installation LED display flatness, can be deviation in longitudinal direction
Control controls deviation within ± 1mm within ± 1mm in transverse direction.But mounted LED display in engineering, it puts down
Whole degree is through actual measurement: deviation in a longitudinal direction is all between >=± 1mm -≤± 10mm, serious >=± 20mm；?
Deviation in transverse direction also all between >=± 1mm -≤± 10mm, serious >=± 20mm.
Using which kind of construction technique technology, it can just make the installation at the scene of LED display unit module flatness
Deviation control in a longitudinal direction, in a lateral direction is even lower under≤± 1mm after the completion, this problem at
Trouble more than 20 years technical problems of LED display industry.
