The ABCD line signal only exists when the dynamic scan is displayed. ABCD is actually a binary number. A is the lowest bit. If the ABCD signal is controlled in binary format, the maximum range is 16 lines. In the 1/4 scan, only the AB signal is required, because AB The signal's representation range is 4 lines. When the line control signal is abnormal, the display of misalignment, highlighting, or image overlap will occur.
The STB latch signal sends the data in the shift register to the latch, and its data content is displayed by the drive circuit lit LED. However, since the driver circuit is controlled by the EN enable signal, the lighting condition must be enabled. The latched signal also needs to coordinate with the clock signal to display the complete image. In any case, when the latch signal has an exception, the entire board will be disorganized.
The EN enable signal is a full screen brightness control signal and is also used for display blanking. Just adjust its duty cycle to control the brightness changes. When an error occurs in the enable signal, the entire screen will appear dark, dark, or trailing.
The CLK clock signal provides shift pulses to the shift register, each pulse causing data to shift in or out one bit. The data on the data port must coordinate with the clock signal to transmit data normally. The frequency of the data signal must be 1/2 times the frequency of the clock signal. In any case, when the clock signal is abnormal, the whole board will be disorganized.
