Driver board parameters

parameter

The  module is a T-CON circuit conversion, LED backlight drive function, backlight PWM adjustment and other functions for small and medium-sized LCD screens. It is applied to 3.5~12.1-inch LCD screens. This board has signal stability, strong anti-interference performance, and convenience. Application Advantages. It has the following functions:
◆The input signal of this board is LVDS single channel 6bit/8bit (default 8BIT mode input; if 6BIT input is required, the resistor needs to be changed to move R1 to the R32 position), and the output is LVDS+T-CON+VCOM signal.
◆This board provides an LED backlight output interface, which can provide stable backlight power supply for 3.5~10.1-inch LCD.
◆This board can accept a wide range of voltage input (Vin) from direct current (DC) +3.3 to +5.5V. It is recommended that the typical input is +5V.

【NOTE1】:
Vin provides the required power supply for the entire board. The recommended typical value is: +5V (ripple is less than 100mV)
【NOTE2】:
ON/OFF is the switch control pin of the backlight. The recommended typical value is: +3.3V/+5V (default is ON: +1.5 ~ +5.5V OFF: 0 ~ 0.3V)
【NOTE 3】:
PWM is the backlight brightness adjustment pin. If the adjustment function is not used, this pin is not connected (NC), and the brightness is the brightest when NC.
The backlight brightness can be adjusted in two ways:
1. PWM: Frequency requirement: 2kHz ~ 10kHz
Amplitude requirement: 5V
Duty cycle: 0~100%
2. Analog voltage: Voltage range: 0~5V
