| With the LED (light-emitting diode) technology has become more sophisticated, people are concerned about the concept of energy conservation, a new dynamic in the form of outdoor advertising signs gradually into people's field of vision. "Sheng card" dynamic set of signs and advertisements Inkjet LED electronic display the characteristics of items, taking both long, both Inkjet advantage of low-cost advertising, but also the dynamic display screen.

After years of struggling companies, innovation, research and development of new products:
|
ZQ1111/ZQ1112 specifically for LED driver designed for one-way transmission application of CMOS chips, especially suitable for multi -
Cross-chip board-level display performance even higher, as well as the application of LED. ZQ1111/ZQ1112 way of using one-way signal -
Lose, the chip on the input signal after the interception of data sent to re-encoding, to avoid an effective multi-chip signaling cascade arising from the accumulated partial
Poor, so as to achieve maximum capacity of 1024 cascade, and to ensure synchronization of data refresh. ZQ1111/ZQ1112 have 3bit PWM
Control signal output per channel depth of the brightness of 4096, to adopt uniform brightness of technology, changes in the gray-scale smooth, delicate.
ZQ1111/ZQ1112 use SOP8 package, integrated internal clock, no other peripheral devices greatly reduce the printed circuit board
Size.
