FAQ:

How to choose the LED Display ?

The LED Display purchase is a very professional look before purchasing these common problems will make you into the role as soon as possible.

Consider the factors of the Display area of the user site can allow

(1) effective line of sight with the actual site size;

(2) pixel size and resolution;

(3) units estimated for the base area;

(4) Display mechanical installation and maintenance of the operating space;

(5) The Display inclination on the distance.

Playback of user needs

(1) text: text size and differentiate demand;

(2) Video Display: 320 x 240 dot matrix;

(3) digital standard DVD: ≥ 640 × 480 dot matrix;

(4) complete computer video: ≥ 800 × 600 dot matrix;

Ambient light level for the brightness of the Display body requirements

The general brightness requirements are as follows:

(1) Indoor:> 800CD/M2

(2) semi-indoor:> 2000CD/M2

(3) outdoor (look northward):> 4000CD/M2

(4) Outdoor (faces south):> 8000CD/M2

Red, green and blue on a white composition brightness requirements

Red, green, blue and white purity aspects of the contribution is not the same. The fundamental reason is because the human eye's retina

Membrane caused by different wavelengths of light feel. After a number of experimental tests, the following approximate ratio, for the reference design:

Simple red, green and blue brightness ratio: 3:6:1

Exact red, green and blue brightness ratio: 3.0:5.9:1.1

High-end full-color display to use pure green

Actual LED Display production, should choose a high luminous efficiency and they can get rich vibrant color trichromatic

LED lamps, so that the chromaticity diagram in the color area of a triangle as much as possible in and close to the tongue-shaped spectrum of color curve to meet the rich color and the issue of sufficient brightness and tongue top-shaped curve for the 515nm wavelength light, so high-end LED Display selection of wavelength close to 515nm pure green light, LED tube, such as the selection of the LED lamp of 520nm, 525nm or 530nm wavelength light.

Clear luminance and dot density requirements under the conditions, the brightness of the computer is a single tube

Calculated as follows: (two red, one green, one blue, for example)

Red LED lamp brightness: brightness (CD) / M2 ÷ Points / M2 × 0.3 ÷ 2

The green LED brightness: brightness (CD) / M2 ÷ Points / M2 x 0.6

Blue LED lamp brightness: brightness (CD) / M2 ÷ Points / M2 × 0.1

For example: 2500 dots per square meter density 2R1G1B, per square meter brightness requirements for 5000 CD/M2 is:

The red LED lamp brightness: 5000 ÷ 2500 × 0.3 ÷ 2 = 0.3

The green LED brightness: 5000 ÷ 2500 × 0.6 ÷ 2 = 1.2

The blue LED lamp brightness: 5000 ÷ 2500 × 0.1 = 0.2

The brightness of each pixel: 0.3 × 2 +1.2 +0.2 = 2.0 CD

Full color Nichia tube with the use of domestic pipe in addition to price What is the difference between

(1) die: Nichia independent production of the die, the domestic pipes generally used die in the United States or Taiwan;

Package: (2) the Nichia independent package, domestic production plant, domestic pipe more packaging manufacturers;

(3) Consistency: Asian tube of the same batch of die wavelength difference between the smaller, consistency, domestic pipe consistency is relatively poor;

(4) Life: Asian tube life is relatively long, domestic tube attenuation more serious;

A control system can control the number of points?

Communication Display A card: monochrome, color, 1024 × 64

Communication Display B card: Monochrome: 896 × 512 two-color: 896 × 256

DVI-color Display: 1280 × 768

DVI Full Color: 1024 x 512

The display size design is generally considered to what factors

- There are three important factors in the design Display size:

(1) to display content;

(2) of floor space conditions;

(3) of the template size (indoor Display) or the pixel size of the display unit (outdoor Display).

-10 Kilowatts or more display should be added to buck the boot device.

- Communication: communication distance is long communication lines for the definition.

- To display models that are installed with the standard of the length of the communication lines to install the communications line.

- Prohibit the communication lines and power lines in the same line of tube alignment.

- Installation Requirements: about the installation of the display level, are not allowed backward

- Lifting to the installation of the upper and lower adjustment lever

- Wall mount mounted forward off the hook

- Floor installation and positioning support bolts.

Display power consumption indicators and power requirements

The power consumption of the display is divided into the average power consumption and maximum power consumption. The average power consumption, also known as power is usually the actual power consumption. The maximum power consumption is power consumption when the startup or full bright extreme cases, the maximum power consumption is the factor of the AC power supply (diameter, switches, etc.) must be considered. The average power consumption is generally 1/3 of the maximum power consumption.

The display is a large sophisticated electronic equipment for the safe use and reliable operation, AC220V power input, or in connection with the AC220V power input connected to the computer must be grounded.

Note: The computer AC220V power input ground is connected to the computer chassis.

Display installation requirements

Power requirements: power supply connection point should be within the size of the Display body

220V electricity supply, FireWire 0 line ground wire; 380V mains supply, three FireWire 10-line ground wire;

FireWire 0 line conductor cross-sectional area of the same; more than 10 kilowatts, the display should be added a buck to boot device.

The communication requirements: the communication distance is based on the communication line length defined.

To display models that are installed with the standard of the length of the communication lines to install communication lines. Communication lines and power lines is prohibited in the same ray tube alignment.

Installation Requirements: about the installation of the display level, do not allow backward

Lifting you want to install and adjust up and down the pole wall mount forward off the hook to be installed before the floor installation to increase the positioning studs.

The design and installation of the outdoor Display should consider what

The main problem of the outdoor Display as follows:

(1) display installed outdoors, often sun and rain, wind and dust cover, poor working conditions. Electronic equipment is wet or excessive moisture will cause a short circuit or even fire, causing the failure or fire, resulting in losses;

(2) The display may be subject to strong electric magnetic attacks caused by lightning;

(3) ambient temperature changes greatly. Display the work itself must produce a certain amount of heat, if the ambient temperature and heat but also bad, the IC may not work properly, and even burned, so that the display system does not work;

(4) wide audience, Far Sight Distance wide horizons requirements; ambient light changes, in particular, may be subject to direct sunlight.

The above special requirements, outdoor display must be:

(1) Display Display and construction of the junction must be strictly water leak; Display body must have good drainage measures, in the event of a smooth water emissions;

(2) lightning protection devices installed on the display and buildings. Display main body and the shell to maintain a good grounding resistance of less than 3 ohms, caused by lightning current discharge in a timely manner;

(3) to install ventilation equipment, cooling, Display the internal temperature between -10 ℃ ~ 40 ℃. The Display behind the top to install the axial flow fan, exhaust heat;

(4) The selection of operating temperature between -40 ℃ ~ 80 ℃ Industrial-level integrated circuit chip to prevent winter temperature is too low so that the display can not be started. ;

(5) In order to ensure the long-distance visible in strong ambient light, we must make use of ultra-high brightness light-emitting diodes;

(6) shows medium use of a new tube of wide viewing angle, wide viewing angle, color pure, coherent and coordinated, more than 100,000 hours life. Media outside the package is currently the most popular with cover along the square tube, silicone sealed, metallized assembly; the exquisite beauty of its appearance, sturdy and durable, with anti-direct sunlight, dust-proof, waterproof, high temperature, anti-short circuit. characteristics of the "defense".
