LED TV Backlight Driver Download, LED Stands for Light-Emitting Diode, an electronic device that lights up when power is passed via it. LEDs are normally red. They are useful for showing images because they can be moderately small, and they don't burn out. Be that as it may, they require more power than LCDs.
LED backlighting technology can be isolated into two groups: the first one is, direct-lit type, and the second one is the edge-lit type. LEDs, utilized in direct-lit type backlighting, can be either white or RGB. The contrasts between these two types and LED power solutions from a system perspective will be investigated in this application note.
LED TV Backlight Driver Board
LED TV is absolutely the same as LCD TV the main difference is that LCD TV utilizes CCFL as backlight and inverter as driver board however LED TV utilizes LEDs as backlight and boost driver board as the driver. LEDs use dc voltage to work, in contrast to typical LEDs, the high power LEDs utilized in TV works at 3vdc per LED. The purpose of the LED driver board is to keep the flow consistent in the LED. On the off chance that the present increment in a LED beyond the foreordained level as prescribed by the assembling the LED will simply come up short.
