P1.9 has the characteristics of high refresh, high grayscale, high brightness utilization, no image retention, low power consumption, and low EMI. Indoor applications are not reflective and display

The screen contrast ratio is as high as 5000:1; it is lightweight, ultra-thin, high-precision, takes up less space for transportation, is quiet, and dissipates heat in universities. This series of products is more than one

The general display screen has a wider color gamut space and faster response speed, which can realize seamless splicing of any size and size, modular maintenance, and its playback

The whole picture has uniform color, high-definition vividness, no sweat spots, bright lines and other abnormal display that are common on ordinary screens, and the picture switching is soft and does not flicker

, The picture quality is very delicate, close to the playback effect of a TV.

Features of P1.9 full-color LED display:

·P1.9 display ultra-fine pitch, high-resolution LED display with high pixel density, suitable for indoor ultra-high-definition close viewing display;

·P1.9 small-pitch LED display has wide color gamut, uniform color, high contrast, high gray and high brush, super stability of radio and television level;

   Advanced research and development technology and reliable components ensure its excellent high grayscale and high refresh rate;

·P 1.9 LED display screen 160° ultra-wide viewing angle, so that the viewer can obtain high-quality display effects at various angles;

·It can be spliced ​​in any direction, any size, and any shape, showing a perfect seamless visual effect;

·P 1.9 ultra-clear LED display die-cast aluminum frame design, the screen body is ultra-light, ultra-thin, space-saving, cost-saving and stylish and beautiful;

   The use of die-cast aluminum material improves the heat dissipation performance and prolongs the service life of the cabinet;

·P1.9 display has high reliability, long service life and low maintenance cost.

P1.9 small-pitch display applications:

P 1.9 LED display is suitable for military and public security, energy, urban management, public information release platform, traffic and transportation, radio and television,

Fixed installation occasions in medical, corporate video conferencing systems, cinemas, education and other fields.

 P1.9 full-color display product advantages:

1. Ultra-light and thin: single cabinet 7.5kG, 100mm thick

2. Ultra-high refresh rate: it can ensure that high-definition cameras and camcorders can capture high-definition and delicate display pictures when shooting

3. Low brightness and high gray performance: in the case of low brightness, the display gray level is uniform and the display consistency is good

4. High contrast: face mask design, black body SMD, non-reflective surface, large viewing angle, good display effect

5. High uniformity of brightness and color: high-quality selected light-emitting devices of the same batch are used to ensure high uniformity

6. Adopt advanced blanking scheme: completely eliminate dark and bright, ghost phenomenon

7. High reliability and long life: the use of in-line adapter board design simplifies the wiring in the box, effectively reduces the problem of poor connection and reduces signal attenuation and high-quality light-emitting devices.

Proof of high reliability and long life

8. Seamless and fast splicing, simple maintenance and repair: the use of lock structure makes splicing operation simple and convenient without tools

9. No noise: silent design, no air conditioning, no fan installation, eliminate noise, reduce power consumption, save electricity and energy

10. Real-time error detection function: It can independently detect whether each LED full-color display screen is in an open circuit state without adding additional external originals, and can eliminate the problems such as crosses caused by this

11. Front maintenance structure: convenient for disassembly and maintenance

Energy saving

The LED display luminescent material itself is an energy-saving product, equipped with a dedicated constant current drive, energy-saving IC and high conversion rate drive power, and the brightness can be automatically adjusted.
