(see TLC59xx products using this feature) LED open detection is a circuit to detect an LED lamp "open" fault at each output. When a LED gets open, a corresponding output of LED driver reaches to ground and the circuit detects this voltage difference. The LED open detection delivers LED lamp failures to a system controller. IDM, Invisible [..]

(see TLC59xx products using this feature) Color brightness control is a circuit implementation to adjust the output current of each color group, OUTR (red), OUTG (green), OUTB (blue) separately inside IC. This is a function to control white balance. The color brightness control can save external components (current setting resistors) in application [..]

(see TLC59xx products using this feature) Brightness control is a circuit implementation to adjust the output current of all output simultaneously. This is like an adjustment of LCD backlight in computer display. For example, the brightness control function is useful in outdoor application systems. In a sunny days, make it brighter; in a cloudy day [..]

White balance is the global adjustment of the intensities of three colors, typically red, green and blue, to realize white color. By mixing R/G/B (Red, Green, Blue) color, we get white light. If one of colors is stronger than the other two, a display viewer can sense it is red-ish / green-ish / blue-ish. Usually its percentage ratio is 3:6:1. LED S [..]

A video image consists of LED lamps with multiple steps of LED brightness. A degree of this step-control is a grayscale. A mixture of three (Red/Green/Blue) "grayscale" images results in full color image. For a smooth video image, a grayscale of over 256 steps is required which is 8bit digital signal. To control LED grayscale, there are 2 [..]

(see TLC59xx products using this feature) Dot correction is a circuit implementation to adjust the output current of each output individually, and correct brightness deviations of the LED lamps connected to outputs. In below example, "initial production" picture shows "un corrected" all white output. Because of matrix placement [..]
