16-Channel Constant Current LED Driver (Eliminate Ghost)

SUM2017E Specifications


1) Features

Eliminate ghost, light staying and noise, accurate color rendition;
Excellent low-brightness-grayscale performance and great degree of linearity, make your picture fine and smooth;
No color temperature deviation between LED modules, High-contrast display;
System Pulse-Width Modulation (PWM), High refresh rate and large 16 bits grayscale;
Fast output response, 20 ns minimum Output Enable (OE) duration;
Lower power dissipation on LED display, energy saving up to 35%; Lower the temperature of module front by 5 degree Celsius;
0.6 ~ 45 mA (6V) high-accuracy constant current output;
Smart output control, lower Electromagnetic Interference (EMI);
Excellent output current matching accuracy: dot to dot: <±3.0% (Max), Chip to Chip: <±6.0% (Max);
Low Diode Knee Voltage, 0.4 V;
Max data clock frequency: 35 MHz;
Schmitt trigger input;
Smart overvoltage protection, avoid undesired signal 'caterpillar';
Professional matching with your application for your best interest;
24/7 continuous work.


2) Output-Constant-Current Characteristic (IOUT)

SUM2017E provides high accuracy matching current between channels and between ICs;
0.6 ~ 45 mA (6V) high-accuracy constant current output;
Low-knee-voltage constant current expands LED forward voltages (VLED) working range, and facilitate power saving of LED screen.


3) Output Constant Current Adjustment

The output current value of each channel (IOUT) can be set to adjust color balance through an external resistor (REXT) or 2 resistors (a common resistor RT and a specified resistor RS). When VOUT is greater than related knee voltage, the output constant current can be calculated by: IOUT = 18.3/REXT;
RT share a same ground wire with the corresponding LED module to reduce noise.


4) LED Supply Voltage (VLED)

The unique Low-Knee voltage can easily achieve low-power-consumption application. Customers can choose from single-power-supply and multi-power-supply lower power dissipation mode.
Sharing a same power supply with LED application lowers power consumption by 20%;
Using separate power supply from LED application lowers power consumption by 35%.


5) Reliability

Power dissipation of an IC mainly rests with package types, a suitable package reduces package thermal resistance.
Heat radiation capability rely on IC packages too. To improve IC reliability, we choose the most suitable IC package for our customers.




Control System Novastar Description :

The system is capable to display warnings, advice, guidance, videos, audios, pictures, flashes, analog clocks, digital clocks, countdown timers, weather info, web pages, humiture, streaming media, RSS, digital count timer, vista clock to audience from hierarchical users in real time;

It is capable of feeding media data (video/text) for multiple LED displays at the same time with each of the these LED displays having its own play program and mapping area (area for showing the media data);

Take the remote control through the network and send out command data to the local LED display controller and to confirm normal operation of the LED display. In return, the control computer could receive status data from the local controller;

A play segment can have multiple page on which the layouts of the windows for media display are different from each other. Each page of a play segment can have multiple windows for media display. The positions and sizes of these windows can be set individually. Multi-date multi-period scheduling is available;

The media properties can be set include the background color, background picture, transparency, volume of sound, display scale, animation for entrance/exit(in/out), animation speed and color, effects, font, style, transparency for texts. Altogether, there are over 40 different effects for text/pictures displaying. With special data processing design, they are efficient and smooth;

Due to problems from decoders or computers, video could be stuck during being played. Stuck prevention function is designed for NovaStudio to escape from that kind of situation. NovaStuio2012 can recover by itself and begin to play next media when the video or sound being played is suck for certain time (normally 10 seconds);

It can continuously monitor the operation of the LED display with its synchronal playing mode;

NovaStudio can lock the computer for security, the key board and the mouse will not work after locking. It can self-recover from severe error. It is capable of being programmed to display an individual message to a LED display at a pre-set date and time;

By creating a copy of the play program files, together with all the media files involved and storing the copy in the hard disk, play program backup can be achieved for security;

Play log can be recorded, check, statistic and exported to Microsoft Excel files, which makes log management become very easy and flexible;

Capable of controlling and displaying multiple font types with flexible size and picture sizes suitable as per the size of the VMS;

Configurable scheduler on date/day of week basis for transmitting pre-programmed message to any LED display unit;

Monitoring the insertion of the USB disk, and automatically play the play program file on USB disk;

Programs exported to USB flash disk can only be safely and reliably plugged and played on computers with the MAC address being bound;

Capable of controlling brightness & contrast through software.
