1 How to ensure the quality of LED display
Anti static LED display electronic display screen assembly factory shall have good anti-static measures. Special anti-static ground, anti-static floor, anti-static soldering iron, anti-static table pad, anti-static ring, anti-static clothing, humidity control, equipment grounding (especially foot cutting machine) are the basic requirements, and should be tested regularly with an electrostatic instrument.
1. Anti static LED display electronic display screen assembly factory shall have good anti-static measures. Special anti-static ground, anti-static floor, anti-static soldering iron, anti-static table pad, anti-static ring, anti-static clothing, humidity control, equipment grounding (especially foot cutting machine) are the basic requirements, and should be tested regularly with an electrostatic instrument.
2. Driving circuit design the driving circuit board on the LED display module and the layout of the driving IC will also affect the brightness of the LED. Because the driving IC output current is transmitted too far on the PCB, the voltage drop in the transmission path will be too large, affecting the normal working voltage of the LED and reducing its brightness. We often find that the LED brightness around the LED display module is lower than that in the middle, which is why. Therefore, to ensure the consistency of display brightness, it is necessary to design the distribution diagram of driving circuit.
3. The nominal current of the design current LED is 20mA. Generally, it is recommended that the maximum use current should not exceed 80% of the nominal value. Especially for the display screen with small point spacing, the current value should be reduced due to poor heat dissipation conditions. According to experience, due to the inconsistency of attenuation speed of red, green and blue LEDs, the current value of blue and green LEDs shall be reduced to maintain the consistency of white balance after long-term use of the display screen.
4. Mixed lamps LEDs with the same color and different brightness levels need to be mixed, or inserted according to the lamp inserting diagram designed according to the discrete law, so as to ensure the consistency of the brightness of each color on the whole screen. If there is a problem in this process, the local brightness of the display screen will be inconsistent, which will directly affect the display effect of the LED display screen.
5. Control the perpendicularity of the lamp. For the in-line led, there should be enough technology to ensure that the LED is perpendicular to the PCB when passing through the furnace. Any deviation will affect the brightness consistency of the set led, and color blocks with inconsistent brightness will appear.
6. The temperature and time of wave front welding shall be strictly controlled. It is recommended that the preheating temperature be 100 5 and the maximum temperature shall not exceed 120 , and the preheating temperature rise shall be stable. The welding temperature shall be 245 5 , and the welding time shall not exceed 3 seconds. Do not vibrate or impact the LED after passing the furnace until it returns to normal temperature. The temperature parameters of wave soldering machine shall be detected regularly, which is determined by the characteristics of LED. Overheating or fluctuating temperature will directly damage led or cause hidden dangers of LED quality, especially for small-size circular and Oval LEDs such as 3mm.
7. When the LED is not on, there is often more than 50% probability that it is caused by various types of false soldering, such as LED pin false soldering, IC pin false soldering, needle and bus bar false soldering, etc. The improvement of these problems needs to strictly improve the process and strengthen the quality inspection. The vibration test before leaving the factory is also a good inspection method.
8. Heat dissipation design led will generate heat when working. Too high temperature will affect the attenuation speed and stability of LED. Therefore, the heat dissipation design of PCB board and the ventilation and heat dissipation design of box will affect the performance of LED.
2 Aggregation of daily maintenance and repair methods of LED display screen
To avoid possible problems, we can choose passive protection and active protection. Passive protection means that users in some Internet cafes, dormitories and other public places can choose to buy displays with tempered glass, which can make your display "invulnerable to weapons and water and fire", but it will affect the color of the display and reflect light; Active protection is to be more careful in normal use, try to keep the items that may cause damage to the screen away from the screen, and wipe the screen gently as much as possible when cleaning the screen to minimize the possibility of damage.
02 Maintain the humidity of the environment
All users who once spilled drinks on the keyboard and caused keyboard damage know this common sense. Don't let anything with moisture enter your LED display. If fog is found, wipe it gently with a soft cloth before turning on the power. If the moisture has entered the interior of the display, the display must be placed in a warm and dry place in order to evaporate the moisture and organics. Powering on the liquid crystal display with humidity can lead to the corrosion of the liquid crystal electrode and permanent damage.
LCD has the closest relationship with our users, so it is very necessary to do a good job of cleaning and hygiene. In fact, the LCD is also particularly easy to get dirty. The white appearance is really good-looking, but if you don't pay attention to maintenance, it will soon turn yellowish; Piano baking paint is really good, but after a week of use, the shell must be full of fingerprints; Even if it is an ordinary black matte material, after a period of time, there must be a piece of dust on the screen. Many users know to clean the LED display regularly, but do you know how to clean the LCD correctly?
*Precautions
For most LED backlight displays, the most vulnerable place is the screen. Generally, the hardness of the screen is below 3H (the hardness of the pencil lead). If you don't pay attention to it during normal use, it is easy to be "accidentally injured" by other devices, and once the screen is damaged, it means that the LED display is basically scrapped.
Well, the above is how to ensure the quality of LED display screen and the content introduction of daily maintenance and repair of LED display screen. I hope it will be helpful to everyone more information and more content are presented on qianjia.com. Welcome to pay attention or click to check!
