Common problems:
Can the constant current driver board be used instead of a certain size of TV?
Answer: As long as the light bar working voltage is within the voltage range of the purchased board no matter how many inches of TV, this product can light it. Note: Here we are talking about just lighting up, not that it is suitable. If you need an exact answer, the best way is to provide the backlight module parameters of the panel (operating voltage of the light bar, rated current, etc.)
If you can't determine how many volts the light bar is, what should you do? This time there is a simple way is to find the original machine above the constant current driver board to see its output filter electrolytic capacitor voltage is how many volts? If it is 100V withstand voltage, it means that the voltage of the light bar will not exceed 80V, if the capacitor withstand voltage is relatively high, choose a high-power power supply board.
After knowing the voltage can point up the situation also need to pay attention to a problem is about the current of the LED lamp beads wafer size determines the rated current it needs, but because of various reasons module factory will choose a variety of different specifications of the lamp beads led to a variety of different rated working current. To solve this problem, we recommend that if it is more than 26 inches of models to use our standard parameters: constant current 480mA, if it is less than 24 inches to reduce the current to half, that is, 240mA. here again have to explain the reality of the problem: 480MA does not mean that it is suitable for so more than 26 inches of the screen, just choose the approximate value, for the case can not determine the exact parameters. According to the feedback from many users before the data back with this current is mostly appropriate, but occasionally there will be too bright and other situations, the easiest way to solve this is through the dimming function foot, connected to the dimming foot after the brightness can be dimmed.
Backlight board common electronic symbol code in English and Chinese are as follows.
a. VCC: power supply voltage positive, circuit power supply voltage (voltage is usually 12V or 24V)
b. ON/OFF, ON, EN, ON_BL, etc.: switch foot, switch signal foot (voltage range is usually between 2.5V-5V)
c. One is digital mode - PWM, one is analog dimming - DC
Analog dimming is carried out through the DC voltage, usually directly to the DC voltage of 0V-5V to control the purpose of the brightness of the adjustable foot).
GND: ground (negative power supply)
LED+:Light-emitting diode (light bar) positive
LED-:light-emitting diode (light bar) negative
The above symbols contain most of the LCD motherboard and the backlight board on the common code, connect as long as the respective code in accordance with the corresponding connection will not be wrong.
