What is Driving IC
LED Driver IC by changing the current or voltage, to achieve changing the brightness of the LEDs, full-color display each pixel has red, green and blue light, each color of light has 255 brightness levels, so the driver IC, can let LED display 16, 581, 378 color of the manifestation.
Driver IC into a constant voltage and constant current I IC, a constant current IC principle is to maintain the current constant by changing the voltage to control the brightness of the LEDs, the principle is to maintain a constant voltage IC voltage constant current control by changing the LEDs brightness, if the LED Screen' LEDs is the heart, then the LED display driver IC is the brain.
MBI Series IC
Macroblock, Inc. is one of the top 10 global suppliers of LED drivers and focuses on IC designs that power the best performance in LED displays. MBI driver ICs are widely adopted by over 500 worldwide customers thanks to MBI's continuous technological innovations. 
MBI5153 drives the corresponding LEDs to the brightness specified by image data. With MBI5153, all output channels can be built with 14-bit color depth (16,384 gray scales). When building a 14-bit color depth video, S-PWM technology reduces the flickers and improves the image fidelity.
MBI5041 is designed for LED video applications using internal Pulse Width Modulation (PWM) control with selectable 16-bit color depth which features a 16-bit shift register which converts serial input data into each pixel gray scale of output port. The output current can be preset through an external resistor. Moreover, the preset current of MBI5041 can be further programmed to 64 gain steps for LED global brightness adjustment.
MBI5035 is a 16-channel constant current LED driver with VDS=0.2V @ IOUT=20mA, which is excellent in power saving compared to the conventional design. MBI5035 is especially designed for low power consumption LED display applications. The low knee voltage (LKV) design makes MBI5035 work at a constant output current with low VDS and still guarantees PrecisionDrive™ feature.
