UCS5603LED grid screen driver IC
UCS5603 up to 4096 gray level 3-channel bad spot relay LED grid screen driver IC
Product overview
UCS5603 is a 4096-level gray three-channel bad spot continuation function LED drive control special circuit, with MCU digital interface integrated inside,Data latch, LED high voltage driver and other circuits. The single brightness of the chip is realized by peripheral MCU control, and the cascaded control is realized by outdoor large screen Color lattice luminescence control. The bad point transmission function adopts the advanced HPD error signal recognition technology, the channel error signal recognition rate can reach More than 99%, and also uses a patented dual decoding engine, while monitoring 2 channels, any channel signal problems in real time switch to positive Normal channel, the human eye is not easy to find the screen abnormal during the switching process. The UCS5603 RGB channel output adopts 4096 level grayscale output, and Add each channel current independent adjustment function, plus ±3 high-precision constant current design, so that the picture effect more restore the real color, rich and gorgeous.
Functional characteristics
- 1. Dual-channel bad point transmission function, the fault point signal can continue to pass down, the overall fault transmission rate of more than 95%, and the picture is good
- 2. Leading HPD error signal recognition technology, channel fault recognition rate of more than 99%
- 3. Patented dual decoding engine, monitor and decode 2 channels at the same time, any channel in use will be switched to normal in real time Channel, and because it is a real-time switch, it is difficult for the human eye to find the abnormal process of the screen when the fault occurs
- 4. The UCS5603 works at any frame rate
Advanced channel fault testing capabilities:
1. Real-time reaction function during channel test: real-time dynamic detection of any channel fault through the test program, the main channel is normally red light, auxiliary;The auxiliary channel is normally green, the corresponding light is not on when any channel fails, and the fault recovery light is on, real-time monitoring, real-time response, This real-time response function facilitates the identification of soft faults occurring at higher frequencies.
2. Dual-channel short-circuit test function: when the two channels of the IC short-circuit, although the production test pattern is normal, but engineering;It is easy to cause instability in various interference environments. Through the UCS5603 dedicated test program, this kind of fault UCS5603;It is effectively identified by the light status when the light is off.

- RGB output port can achieve 4096 gray level, port refresh frequency 2K
- ±3 high constant current accuracy design
- RGB Each channel current can be independently set by software, divided into 16 levels
- UCS5603A: 1.5mA to 24mA, range 1.5mA, default power-on current 18mA
- UCS5603B: 3mA to 48mA, range 3mA, default power-on current 36mA
- UCS5603 Data transmission frequency 800K/ s. When the screen refresh rate requires 30 frames/second, 740 points can be cascaded. Picture refresh rate At 60 frames per second, 370 points can be cascaded. Lower frame rate requirements allow more points to be cascaded
- chip VDD built-in 5V voltage regulator, output port withstand voltage up to 30V
- Power on. All RGB channels are turned off, black
- Low-voltage enhanced technology design, the UCS5603 can operate stably at as low as 2.5V, greatly reducing interference caused by power fluctuations
- S-AI anti-interference patented technology, can greatly reduce and filter radiation interference and conducted interference
- S-Drive technology and enhanced receiving technology greatly enhance the connection distance between points
- industrial design, stable and reliable
- Symptom: Through the UCS5603 dedicated test program, this type of fault UCS5603
- It is effectively identified by the light status when the light is off
