General Description
LED Electronic Display Overview
LED Electronic Display System is a multimedia hi-tech product that has blended optical, electronic and acoustic signal processing technology, and it includes the following devices :
Display screencontrol cards and communication systemand its related peripheralperipheral, such as HD DVD, video processorsoftware
(See the LED display system diagram at the bottom of the document.)
System Features:
Available for connection to an external scanner, and accepting various pictures, graphs and handwriting inputs. video signal (TV, VCR, DVD), and showing dynamic images, and it also can show graphs and animations. control computer can act as a workstation on network, and read real-time data from specified computer, and show them on the display. methods for image display, and easy operation for scheduled programmings at any time (including play sequence, time length, etc.)
Protection for outdoor displays
They include waterproof, protection against UV, sun-screen, antistatic, damp proof, anti-freeze (and if necessary, anti-thundering) and other features.
Characteristics of the led display:
Displaying videos in high resolution
The display is designed to provide visual effect similar to that of analog formula, without losing image data.
-Providing perfect Gamma CorrectionIt is designed to offer perfect Gamma Correction made continuously in each R,G,B 16,384 steps.
-Offering automatic brightness adjustmentIt can automatically adjust the screen's brightness according to the informatiom got from the light probe (on the multifunction card). Eg: in the middle afternoon , the brightness can be 6000cd/m2, when the evening coming, the brightness can be reduced to 3000cd/m2 step by step to save power and the life-span time of the screen .
-The display can be used to broadcast News, Live Sports, Entertainment, Public Service Announcement or Special Events with multiple inputs.(TV, Satellite, Color-Camera, DVD, VHS / NTSC, PAL, SECAM)
-The screen turns on and off automaticallyThe customer can first scheduled the work time and the contents of the screen according to the software. The screen will work as scheduled, no need people to do the operation . Also several windows can be opened at one time to broadcast different contents.
-Perfect transmission of digital signalThe display is prevented from the screen quiver or mis-operation because it is designed to transmit digital signal in perfect timing between modules and controller. (signal transfered in “Z” form ) the customer can set up the cabinets arbitrarily.-Remote control and monitoring through Public Networks (needing customized order, need support of local network) (LAN Net work, Optical Fiber Cables, Internet Network)
-Stable Operation under Microsoft Windows NT, XP and Latest Version-Easy for operation and maintenanceThere are signal lights, reporting whether or not the signal and the power are transferred smoothly. If something wrong, the lights were turn off or inormal, then people will know where is the problem and do which kind of change. It is very convenient for the customer to do the repair on some giant screen.-Superior UniformityUniformity is a measure of picture consistency across a display. The ratio of lowest brightness to the highest brightness is strictly controlled within 1:1.2. The wavelength difference of the leds in one display is within +/-1.5nm.
-Long life-timeFrom the use of the strictly choosen materials, we only cooperate with the high quality suppliers. For the led lamp, we use famous brand leds for our high quality video screens. The life-time for the lamp is up to 100,000 hours.-High refresh rateThe refresh rate for static can be up to 8,000Hz.-High speed of open/close timeThe special driver IC open/close time can be 50nS. High speed of open/close time makes sure that the whole screen image is more fluent, especially when it shows the F1 car match. It has 14 bit processing technology.-Innovative heat management SystemAlthough LED lamps produce very little heat individually, if enough current is applied to a large number of LEDs, significant heat build-up and equipment damage can occur. To prevent this, specially designed the panels to minimize the internal heat build-up, thus eliminating the need for external cooling system. This is specially popular for rental business.-Value keeping serviceThe display can offer the screen auto brightness control. With use of the display control system software, it can re-adjust the brightness again.-Cost SavingWith our unique design on the drive board, and our choice of special control IC and the software, the leds canrelease high brightness but just with half current(17-18mA, the normal one is 20-30mA)-Screen size adjustmentThe screen's design can not only be the standard ratio of 4 : 3 or 16 : 9, but also be customized.-The aperture between each two cabinets is less than 0.5mm. So the screen can be very smooth.
