The meaning of different signals, LED display description

Hello everyone, we Shenzhen Dejian Optoelectronics Technology Co., Ltd., we specialize in the production of LED display, LED electronic display, indoor full color LED display, outdoor full color LED display, LED large screen, etc., oh, there are car display Screen. We have cooperation with many customers across the country. Not only domestically, we also go abroad and have customers overseas. Customers are very satisfied with our services, technology and products. If you have any need, you can inquire, today to explain to you below the LED display if there are different signals, the meaning of the representative, please look at the content:

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.

EV Drive Motor Stator Varnishing Machine

The trickling technology is used for the insulating treatment of stators to achieve the insulating function as desired. With multiple fixture design, this solution has the advantage of fast model changeover. The automation, cycle time are adjustable based on the customer specifications. HMI is adopted for operators to check product parameters and enable the robot to communicate with the other production lines both in front and at the back of the varnishing production line at the customer workshop.

The copper coil of the electrical motor's stator will be varnished after preheated. Then the stator will be unloaded before cured and reweighing to achieve insulation effect. The servo trickling module, high-accuracy scale and data traceability help avoid varnish stains on the stack,which is very competitive in the industry. It boasts of fast model transfer with multiple fixture designs and automatic nozzle positioning.
