Dignity Series /
Dignity series is a GST-COB display designed specifically for the rental
market. The strict epoxy resin packaging technology makes the screen
exquisite and excellent protective performance. Advanced chip control
technology allows the cabinet between the optional placement, plug and
play. Unique cabinet design concept, can easily module interchange, arc
splicing.
It is these advantages that make screen easy to apply to
three different occasions: indoor/outdoor/ground screen, which are very
popular with new and regular customers.
GST-COB surface treatment and mounting device technology/
Dignity series apply is not the traditional lamp bead patch technology, but the national patent gst-cob surface treatment and mounting device technology. The LED lamp is sealed with epoxy resin through special process, supplemented by professional surface treatment technology, the lamp bead is completely sealed with the gap between the circuit board and the LED lamp pin welding plate, forming the state of vacuum protection.
● GST-COB module and traditional module comparison
● IP65 High protection grade
? Noarex xantar flame retardant special material full package cover, high flame retardant property, good stability, anti-deformation， protection grade IP65, waterproof, dustproof.
? The screen is treated with epoxy resin surface, to prevent knock against, Loading and unloading moving is more easier.
? The surface treatment technology of epoxy resin can effectively form the vacuum protection device, anti-oxidation, anti-static, moisture-proof.
● 160°Wide Viewing Angle
Original Angle of view technology, the upper， lower， right and left viewing angle are above 160 degrees, no dead angle and no color deviation are observed, the image display cover area is larger.any angle is perfectly
● Lamp beads last longer
The special epoxy resin surface treatment technology can effectively protect lamp bead, reduce the repair rate, reduce the dead lamp probability, increase the service life.The whole screen heat dissipation performance is better.
Intelligent chip processing technology /
Dignity series use high quality special IC chip,high precision power output,high grey high refresh,and with PWM function green energy saving.
● Intelligent correction
Fixed installation supports flash correction function, it is not affected by usage frequency and time attenuation,more convenient, one-second correction, saving time and cost.
● Picture exquisite
3840Hz ultra-high refresh display, eliminates ghosting no trailing, gray processing depth reaches to 14-16bit, making display picture more clear and exquisite, and the playing effect is bright and smooth.
● No fan design
Advanced technology design layout and material selection, high heat dissipation panel treatment technology, natural heat dissipation, ultra-quiet no fan design, energy saving, longer life.
● Intelligent read back
After module needs to be replaced or broken light is repaired, built-in intelligent chip can quickly carry out the single module correction data storage and intelligent readback function.
Improved design of cabinet /
Installation of dignity series is also targeted at some difficult and painful points of the rental screen over the years. The assembly and replacement process of cabinet and module are greatly improved， to make the installation of rental screen truly reach to high-speed and effective.
● Module exchange
Under same cabinet, P2.97 module can be replaced with P2.6 module, or P2.6 module can be replaced with P2.97 module.Picture quality visual range adjustment is more convenient.
● Cabinet free exchange
Under the terminal control program, cabinet of dignity series and screen can be freely interchangeable, plug and play.No longer need to label cabinet, also no longer need to be tedious debugging procedures.
● Front&back maintenance
Double LED lamp board and die-casting aluminum rear cover constitute a module of 500*250mm, implementation front and back maintenance, and can be adapted to all kinds of space-limited operating environments while ensuring flatness.
● Arc splicing
Between cabinet can be plus or minus 10 ° arc joining together, meet the demand of different curve splicing, to adapt to a variety of architectural appearance, realize all kinds of creative splicing display.
● Module design optimization
? Seal improvement
Traditional module direct sealing the lamp panel and the bottom shell with glue,which is difficult for module maintenance.The dignity series module adds waterproof groove between the middle and bottom shell ,and adds sealed waterproof ring, which can not only guarantee the waterproof performance of the module, but also realize quick maintenance.
? Interface improve
Module adopts method of no-line connection. We increase the interface height，combined sealing waterproof ring.Stability is higher and waterproof effect is better.
Application area /
? Education publicity: interactive systems such as school parks and training institutions .
? Transportation industry: airport, railway, subway, highway and other information display.
? Commercial demonstration: TV studio, large performance, commercial exhibition, hotel lobby, shopping mall, etc.
? Cultural place: library, museum, show information of related cultural enterprises and institutions.
? Government department: publicity for the people, guidelines, open government affairs, etc .
