Asthe most expensive and most used component of LED display screens, LED lampbeads are a very important part of LED display screens, so what impact willdifferent lamp beads have on the display screen? The impact of LED lamp beadson the LED display is mainly manifested in the following aspects:

1.     Brightnessof the Led Display

Brightnessis an important determinant of display brightness. The higher the brightness ofthe LED, the greater the margin for the use of current, which is good forsaving power and keeping the LED stably.

LEDshave different angle values. When the brightness of the chip is fixed, the smallerthe angle, the brighter the LED, but the smaller the viewing angle of thedisplay. Generally, at least choose a led display with a viewing angle of 100degrees or more to ensure a sufficient viewing angle of the display screen.

2.     Lampbeads quality and failure rate

TheLED display is composed of 10,000 or even hundreds of thousands of red, green,and blue LED lamp beads. LED lamp beads slowly decay with the use of time. LEDlamp brightness decay speed and LED chip, auxiliary materials, packagingprocess have a certain degree of correlation.

Ingeneral, after 1000 hours and 20 mA normal temperature lighting test, the attenuationof red LED lamp beads should be less than 7%, and the attenuation of blue andgreen LED lamp beads should be less than 10%. The consistency of red, green,and blue attenuation has a great influence on the white balance of the full -color LED display in the future, and thus affects the display fidelity of thedisplay.

Atthe same time, good lamp beads have a low failure rate, according to industryexperience, the failure rate from the start of the assembly of the LED displayto the 72-hour aging before shipment should be no more than three tenthousandths (referring to the failure caused by the LED lamp beads itself).

2.     WorkingLife of LED Display

Itis estimated that the average lifespan of an LED display is between 60,000 and100,000 hours, depending on the use of the screen, which is much longer thanthe working life of other parts of the LED display. Thus, in the best - casescenario, this would be equivalent to using an LED screen for six hours a dayfor 45 years. Therefore, as long as the quality of the LED device isguaranteed, the working current is appropriate, the PCB heat dissipation designis reasonable, and the display screen production process is rigorous, the LEDdevice will be the entire display screen. One of the most durable parts of themachine.

Hereare our tips to increase an LED displays lifespan: Avoid places that are toowet or too sunny Always place your screen on a flat surface Use a surgesuppressor and a voltage regulator. Do not touch the screen with your fingersUse a surge suppressor and a voltage regulator.

3.     Consistencyof Display effect

Thefull - color display is composed of countless red, green, and blue LEDs. Thebrightness and wavelength consistency of each color LED determines thebrightness consistency, white balance consistency, and chromaticity of theentire display.

Toachieve the matching consistency of the brightness changes of the red, green,and blue LEDs at different angles, it is necessary to strictly carry out thescientific design in the package lens design and raw material selection, whichdepends on the technical level of the package supplier.

4.     Size ofLed lamp beads

Inthe premise of the dot pitch remains unchanged while the LED lamp beads size increases,the display area will increase, too. However, with the reduction of the blackarea, the contrast will be weakened. On the contrary, when the size decreases,the contrast will be improved.

Last,How to Choose LED Lamp Bead? After knowing the influences that LEDs bring tothe whole screen, you may have already realized the importance of choosinggreat, high - quality LED lamp lights for your functional LED display. So, howwe can choose the right products? There are some tips for you.

1)    Checking the solder joints

LEDmanufacturers usually use the SMT SMD process and apply solder paste and reflowsoldering technology.

2)    The cleanliness of the surface of LEDs.

Ifapplied SMT process, the surface should be clean without too many impuritiesand stains.

3)    The chip

Thechip is the decisive factor that determines the overall quality of lamp beads.In general, the more stable the chip is, the brighter the LED lamp beads are,and the better the heat dissipation is.

4)    The glue

Generally,good products will apply imported glue, and the lamp beads will not deform whenpressed by fingers but low - quality ones will appear deformation or evencracking

5)    The packaging technology

High- quality LED lamp lights can perform uniform color and good consistency, andthis is inseparable from good machinery and equipment.

6)    Color consistency

Poorquality lamp beads will appear in brightness disunity, and there may be obviousdark areas.

7)    Reliable suppliers

Choosingsuppliers with a good reputation such as Nationstar, Kinglight, Hongsheng,Huaxin, and so on can reduce the risks of performance failure.
