What are the causes of women's amenorrhea?

Women have many problems during menstruation. Problems that occur during menstruation may indicate that the body has a disease. When women have amenorrhea, they must pay attention. Because there are many reasons leading to women's amenorrhea, female friends should promptly go to a specialized gynecological hospital when they experience amenorrhea. What is the cause of amenorrhea caused by the diagnosis, targeted treatment.

1, if the woman is eating contraceptives for a long time, this will directly inhibit the female body of female hormone production, which is one of the more common reasons for women not to menstruation.

2. If you suffer from certain gynecological diseases, such as endometritis, cervix adhesions and other genital problems, then this is also the reason that women do not come for long-term menstruation.

3, the lack of protein and other nutrients will also cause women's amenorrhea phenomenon. If women have fewer proteins, hormone secretion will be suppressed accordingly. Without estrogen stimulation, the physiological activity of the uterus may stop.

4, if the spirit of high tension will also make many women long-term menstruation does not come. Excessive fatigue or mental instability affects the nervous system. The abnormal nervous system has an effect on endocrine secretion.

Customized Led Display

P25 full-color display module, the so-called interface mainly refers to a drive mode required by the display, which can be 75 interface, 12 interface, or your specific interface definition, display drive mode, display scan Way, and a driving method to turn on the light. The interface of our P25 dual-color display module uses 12 Port, not port 75.

Process flow of P25 two-color display module-AI automated production:
The designed circuit board is produced, then all the driver ICs are attached, all the corresponding LEDs are prepared, and then the assembly line is ready to start the operation, the AI vertical machine starts to insert the lights, the DIP starts, and all the LEDs Knit the tape, then put it in the Universal vertical machine, start to insert the LED directly, according to the set procedure, insert the entire LED board

After all the completed P25 dual-color display modules have passed the company's quality management inspection, and there are no problems, the product is put into wave soldering, and then all the LED pins are soldered, using environmentally friendly lead-free Tin
3. The process flow of P25 two-color display module-quality inspection

All the soldered full-color display modules begin to work on the assembly line. All accessories, such as the angle of the signal line of the line driver, and various power sockets, and the entire light board, if there are any, crooked The oblique LED lamp bead will right and level the LED lamp bead for comprehensive inspection.

Our P25 two-color display module all use the JX5020 driver chip from Taiwan Macroblock. The LED of each branch has a corresponding IC pin driver, and one IC pin drives one LED. We use The static cross-current driving method ensures that the current of each IC can be guaranteed, and it will not cause the entire module to heat up due to the different scanning methods, resulting in damage to the IC, and the brightness of the LED. Static cross flow is related, and the static cross flow drive ensures the stability of the entire screen.

When all the LED display modules are tested, paste QC, pass, and then perform the first semi-finished product test aging. The longer the aging time, the better, let him exceed 24 hours as much as possible, and then we will display the display module , Put on the bottom shell, ready to start pouring

Process flow of P25 two-color display module-mechanical glue filling:
The glue filling adopts a fully automatic glue filling machine. After the ab component glue is combined, the filling is carried out according to the ratio of 10:1. It is best not to lower or increase the ratio. The ratio of 10:1 is just right. , It can be surface-dried in about two hours, and the glue will dry out in about 4-6 hours. This glue will have a good guarantee for long-term use.

After the module is filled with glue, place the module on a horizontal plane, and test with a level meter, and then try to make each module as flat as possible, complete the 4 corners of the horizontal position on the same level, the choice of AB glue It is also very important. The AB glue choice must use more than 40 yuan per kilogram of glue. Its adhesion and durability will be very good. It cannot be filled with shoddy glue. It will crack after a long time. The screen will leak.
Then put all the display modules in the mask and arrange them to start packaging

P25 full color display module application:
It can be used in a single module or in a combination of multiple modules. When multiple modules are used in combination, the positive pole of the power cord between the two modules is connected to the positive pole (red), and the negative pole is connected to the negative pole (black); the signal passes Signal line docking,.

P31.25 dual pornographic newspaper board LED display module is widely used in traffic guidance and related application fields in highways, tunnels, urban roads, major highways, road network dense areas, urban highways, streets, airports, docks, stations, etc.

Continuous working time: ≥72 hours

The P33.33 outdoor full-color plug-in LED display module has the characteristics of high water resistance, high luminous efficiency and long service life. Its display effect is good, the color is bright, the brightness is high, and the viewing distance is long. It is very suitable for use as an outdoor traffic variable information screen and outdoor advertising screen.

P33.33 Outdoor full-color plug-in light LED display module product features
★ High brightness: using LEDs with the highest brightness, it is still clearly visible at a long distance under strong sunlight;
★ High uniformity: the color uniformity of the display screen**, the display screen is more delicate;
★ Good flatness: The flatness of the module mounting surface is required to be controlled within plus or minus 0.1mm;
★ Good effect: using nonlinear correction technology, the image is clearer and the sense of hierarchy is stronger;
★ Patented mask: unique downward tilt angle design to reduce waste and increase the effective viewing angle;
★ Strong reliability: adopting multiple scanning technologies and modular design technology, higher reliability and stability;
