LED Display Purchasing Guidance:
What need to be considered when deciding the size of the display?
1) What is the minimum watching distance and then decide the size of the display according to the actual space.
2) Pixel pitch and resolution
3) The space for installation and maintainence
4) The angle from the display to the ground
What content do you want to show?
1) TEXT. Based on the size of the text and the resolution need.
2) Normal video.320 x 240 dot matrix
3) Number standard DVD display: ≥640 x 480 dot matrix
4) Complete computer video: ≥800 x 600 dot matrix
What are the requirements for the led display brightness according to the Environmental brightness?
General requirement for the brightness are as follows:
1) Indoor:>800CD/M2
2) Semi indoor: >2000CD/M2
3) Outdoor( facing North):>4000 CD/M2
4) Outdoor( facing south):>8000CD/M2
Requirement for the brightness of RED, GREEN and BLUE when show white:
RED, GREEN, BULE plays different role when showing white. The fundamental reason is due to the human eye retina
has different feeling for different wavelengths of light. After a large number of experiments and rest, we come to
the following ratio for the reference: Simple red-green-blue light ratio: RGB 3:6:1 accurate brightness ratio:
3.0:5.9:1.1
Why the high quality led display requires pure green led?
In the production of the led display, we should use the trichromatic LED lamp with high lunimous efficiency and rich
color. So that in the chromaticity diagram of color in the triangle area and near the tongue as far as possible in the
color spectrum curve, to meet the needs of rich color and the issue of sufficient brightness and the tongue-shaped
curve for the 515nm wavelength of light best, so high-end LED display selected wavelength close to 515nm pure green
LED light pipes, such as the choice of 520nm, 525nm or 530nm wavelength LED light tube.
Why choose DVI graphics card standard interface?
1) DVI graphics card interface is in line with international standards for the computer interface
2) No need to open the chassis, can be easily installed;
3) High-memory and strong dynamic screen display capability
4) Good compatibility of hardware and software
5) Supports all operating systems and application software
6) High-volume production, low cost, easy maintenance.
Can the display be controlled with Laptop?
no, Laptop ¡s graphics card is built-in, there is no DVI port, can not be achieved in connection with the control system.
What are the differences of NICHIA chip and othe domestic led chip except price?
1) Chip: Nichia company produce their chip independedtly while the domestic company always use the chips from
America or Taiwan.
2) Packaging: Nichia company packaging independently, no branch factory in China.But for the domestic chip, there are
many factories do the packaging.
3) Consistency: for the Nichia led in one lot, the wavelength has little difference, But for the domestic led,
consistency is relatively poor
4) Life span: Nichia led has relarively longer life span, Domestic led attenuate faster.
Indoor full-color module and SMD full-color display, What is the difference?
1) light-emitting parts: the module full color screen display is generally green, the price of pure green module is higher;
SMD generally use pure green chip;
2) image quality: full-color pixel module looks rough, low brightness and there always mosaic;SMD full color led display
has better consistency and higher brightness;
3) maintenance: full-color module is not easy to maintain. The cost of replacing the entire module is high; the SMD
full-color module is easy to maintain, maintenance can be carried out by replacing a single lamp;
Can the SMD3528 used for outdoor display? Why?
No. Outdoor screen has high demand of installation and structure, SMD3528 LED unable to adapt to the harsh outdoor
environment; at present SMD display can not to meet brightness requirements of outdoor display
Why it takes longer time to produce outdoor display?
1) procurement of raw materials: purchasing the led takes long time, specially when you have to import , it takes even
longer time.
2) the complexity of production process: subject to PCB design, production casing, irrigation plastic, tune white
balance, etc.;
3) the structure of demanding: the general design for the box, need to consider wind, rain, lightning and so on.
How to help customers choosing the right display?
1) what need to be shown?
2) viewing distance and viewing angle
3) resolution requirement
4) requirement of environment
5) cost control
What is the genaral ratio of width and hight for the display?
Picture and text: subject to what you want to show.
Video display: normmaly it is 4:3 or near this proportion. Ideal proportion is 16:9
How many pixels can one control system control?
Communications screen Card A: single color, dual color 1024 x 64
Communications screen Card B: single color: 896x512, two color;896x 256
DVI dual color display:12801x768. DVI full color led display: 1024x512
what are the factors to consider when design the size of the screen?
when design the size of the display, there are 3 factors very important.
1) the needs of displaying content
2) space limitation
3) according to the module size and resolution
More than 10 kilowatts buck should start screen equipment.
Communication requirements: communication distance is long for the definition of communication.
To be installed to display the type of communication lines used by the length of the standard to install communications
lines.
The prohibition of communication lines and power lines in the same pipe line alignment.
Installation requirements: about the level of the installation screen does not allow backward - to the installation of
lifting up and down adjustment rod - wall to be installed before installing forward off hook - landing position to
increase support for the installation of bolts.
Indicators display power consumption and power requirements of what?
Screen is divided into the average power consumption of the power consumption and maximum power consumption. Also
known as the work of the average power consumption is usually the actual power consumption. Power consumption is the
largest start-or full-bright at the time of extreme circumstances, such as power consumption, maximum power is AC
power supply (wire, switches, etc.) must take into account the elements. Average power consumption is generally the
largest power of 1/3. Display is a large-scale precision electronic equipment, safe use and reliable to work, its power
supply input AC220V or AC220V power supply connected to the computer ¡s input must be grounded. Note: The
computer ¡s power supply input AC220V grounding terminal connected with the computer chassis.
Display of the installation requirements?
Power requirements: power supply wiring should be in the body size of the screen 220V electricity power supply,
FireWire grounding line 0 line; 380V electricity supply, the three 10-line ground line of fire line; the front lines with
the 0-line the same wire cross-sectional area; more than 10 kilowatts buck should start screen equipment.
Communication requirements: communication distance is long for the definition of communication. Installed to display
the type of communication lines used by the length of the standard to install communications lines. Prohibition of
communication lines and power lines in the same pipe line alignment. Installation requirements: about the level of the
installation screen, do not allow the dumping after the lifting rod to regulate the installation of up and down before the
installation of wall mounted hook falling forward landing position to increase support for the installation of bolts.
What issues should be considered for outdoor screen design and installation ?
The main issues of outdoor screens are as follows:
1) Screen installed in the outdoor sun and rain often, the wind dust cover, the work environment. Electronic equipment
to be wet or damp can cause serious short-circuit or even fire, and even lead to failure of fire, resulting in losses;
2) Screen may be caused by strong electric lightning attack Magnetic;
3) Significant changes in ambient temperature. Display the work itself should have a certain amount of heat, if the
ambient temperature and the heat is too high and non-performing, integrated circuits may not work correctly, and
even burned down, so that shows that the system does not work;
4) Wide audience, require line-of-sight distance requirements of wide field of vision; ambient light changes, in
particular, may be subject to direct sunlight.
The special requirements of the above, outdoor display must be:
1) Screen body and the screen body and architecture must be strictly waterproof junction leakage; screen body in
order to provide good drainage measures, in the event of a smooth water emissions; (2) and building on the screen to
install lightning protection devices. The main screen and the casing to maintain a good grounding, grounding resistance
is less than 3 ohms, so that high current caused by lightning discharge in time;
3) The installation of ventilation to cool the screen so that the internal body temperature of -10 ℃ ~ 40 ℃ between.
Screen behind the body above the axial fan is installed, from the heat;
4) Choice of working temperature -40 ℃ ~ 80 ℃ industrial level integrated circuit chip, the temperature is too low
to prevent the winter so that the screen could not be activated. ;
5) In order to ensure a strong ambient light in the case of remote visualization, we must choose ultra-high brightness
light-emitting diodes;
6) Shows that the new optional wide angle medium tube, wide angle, color pure, consistent coordination, more than
100,000 hours life. Show that the outer packaging for the media the most popular along with over a square cylinder,
silicone sealed, non-metal assembly; its refined aesthetic appearance, sturdiness and durability, with the anti-direct
sunlight, dust-proof, waterproof, anti-high temperature, anti-short-circuit the "Five Anti" feature.
