What is the LED point light source internal control?
In a full screen, LED, ranks separately, each diode are connected to a power supply, driving different diode shows a different picture, the diode switch by internal control is the internal source ~ ~ ~ what you do not understand, can be explored in detail.
By sampling the current value of one of the darkest LED in your LED lattice as a sampling point, the driver keeps the brightness of the entire lattice by controlling the current of the other LED and the current of the LED. This is point light control. What questions can we discuss with each other?.
