LED display FAQ:
1. Consider allowing users to the venue of the screen area of the factors which?
(1) the effective line-of-sight and the actual size of the venue;
(2) pixel size and resolution;
(3) the size of the base unit is estimated;
(4) Screen mechanical installation and maintenance operations space;
(5) screen angle of the impact of the distance.
2. User needs playback what?
(1) Text Display: as text size and differentiate their needs may be;
(2) ordinary video display: 320 × 240 dot-matrix;
(3) digital standard DVD Show: ≥ 640 × 480 dot-matrix;
(4) complete computer video: ≥ 800 × 600 dot-matrix;
3. Screen brightness of the environment which brightness?
General brightness of the following:
(1) indoor:> 800 CD/M2
(2) semi-indoor:> 2000 CD/M2
(3) Outdoor (sitting Southern Dynasties North):> 4000 CD/M2
(4) Outdoor (sit Northern Dynasties South):> 8000 CD/M2
4. Red, green, blue and white in the composition of what kind of brightness?
Red, green and blue in white Condition contributions is not the same. The fundamental reason is that the human eye of the retina at different wavelengths of light caused by the different feeling. After a large number of experimental tests have approximately the following ratio for the reference design: red, green, blue brightness than simple: accurate 3:6:1 ratio of red, green, blue brightness: 3.0:5.9:1.1
5. Why use high-grade full-color display of pure green?
LED display in the actual production, should choose a higher luminous efficiency can be rich vibrant color of the three-color LED lamp, so that in the chromaticity diagram of the color triangle area as far as possible and close tongue-shaped curve color spectrum to meet a rich color and the brightness and enough tongue-shaped curve for the top 515 nm wavelength light, high-grade LED display closer to 515 nm wavelength selection of the pure green LED light tubes, such as the selection of 520 nm, or 530 nm wavelength of 525nm light LED lights tube.
6. In the clear brightness and the density requirements under the conditions of how the brightness of the single computer?
Calculated as follows: (two red, one green, one blue for example) red LED brightness: brightness (CD) / M2 ÷ Decimal / M2 × 0.3 ÷ 2 green LED brightness: brightness (CD) / M2 ÷ points / M2 × 0.6 blue LED brightness: brightness (CD) / M2 ÷ Decimal / M2 × 0.1
For example: 2500, the density per square meter, 2 R1G1B per square meter brightness requirements for 5000 CD/M2,: red LED brightness: 5000 ÷ 2500 ÷ 2 = 0.3 × 0.3 green LED brightness: 2500 × 5000 ÷ 0.6 ÷ 2 = 1.2 for the blue LED brightness: 5000 ÷ 2,500 = 0.2 × 0.1 per pixel brightness: 0.3 × 2 +1.2 +0.2 = 2.0 CD
7. Why use DVI display interface standards?
(1) DVI display card interface is in line with international standards computer display interface;
(2) without opening the chassis, and the convenience of installation;
(3) memory, dynamic images showed strong;
(4) hardware and software compatibility strong;
(5) support for all operating system and application software, display flexibility;
(6) mass production, low cost, easy to maintain.
8. Display can be controlled by laptop, and why?
Not. Laptop is the built-in graphics, can not be realized with the connection to the control system.
9. All of the use of color and use of domestic, which except for the price difference?
(1) of the core: the independent production companies of the core, the general domestic use in the United States or Taiwan chip companies;
(2) Package: Asia, the company independently package, no domestic production factories, domestic manufacturers of packaging more;
(3) Consistency: on the same batch of the core difference between the smaller wavelength, consistency, and consistency of homemade relatively poor;
(4) life: the life of the relatively long, and domestic production of more serious decay;
10. Indoor module and patch all full color screen What is the difference?
(1) LED: Module full color display module is generally yellow and green, pure green module prices more expensive; patch all general use pure green color of the core;
(2) effect: Module full color pixel visual feel coarse, low brightness, susceptible to mosaic; patch all better color consistency, higher brightness;
(3) Maintenance: Module not maintain full-color, high cost of the replacement block module; patch full color easy to maintain, can be replaced with single lights repairs;
11. Outdoor screen can be affixed LED table, and why?
Not. Outdoor screen installed stringent structural requirements, the inability to adjust to outdoor LED patch the harsh environment; outdoor higher screen brightness, not to patch outdoor LED screen brightness requirements.
12. Outdoor screen relatively long production cycle Why?
(1) raw materials procurement: LED lamp procurement cycle longer, especially imports of batteries, ordering cycle takes 4-6 weeks;
(2) production technology complex: to the PCB design, Shell production, irrigation plastic, white balance transfer;
(3) Structural demanding: general design for the box, to consider shielding, rain, lightning, etc..
13. How to help users select the appropriate screen?
(1) display needs;
(2) visual distance from the Perspective of recognition;
(3) resolution of the screen;
(4) installation of environmental requirements;
(5) the cost of control;
14. Display the length and width ratio is general?
By Screen: According to determine the content displayed; video screen: generally close to 4:3 or 4:3; ideal ratio is 16:9.
15. A control system can control points?
A screen communications cards: monochrome, two-color 1024 × 64 communications Screen B cards: Monochrome: 896 × 512 two-color: 896 × 256 DVI two-color screen: 1280 × 768 DVI-wide screen: 1024 × 512
16. Display installation requirements?
Power requirements: power supply should be in the wiring of the screen size of 220 V power - electricity, grounding line FireWire 0; 380V electricity supply, three FireWire 10 grounding line; FireWire and 0 wire line the same cross-sectional area; display more than 10 kilowatts should be activated relief equipment.
Communications requirements: communications lines long distance communications for a definition. To the screen models installed by the length of standard communication lines to install communications lines. Prohibition of communications lines and power line in the same line of the alignment.
Installation requirements: the installation screen around, do not allow the dumping after loading to regulate the installation of upper and lower-Mount installed before leaning forward with the installation shedding hook landing position to increase support bolts.
