First, the product design.
Full-color LED display a wide range of indoor and outdoor energy-saving products such as portable highlight high refresh everything, all walks of life on the LED display requirements are different, so buyers in resolution LED display LED display when the quality and choice To set your own needs, whether manufacturers LED display products to the greatest extent consistent with their needs.
Second, the white balance.
White balance is one of the most important indicators of the LED display. Red, green and blue color science taken in the ratio of 1: 4.6: 0.16 pure white will show, if the actual proportion of any deviation occurs the white balance bias, usually pay attention to whether there are bluish white, yellow green phenomenon. White balance is mainly determined by the quality of the LED display control system, lamp beads for color reduction also affected.
Third, the brightness and viewing angle.
Indoor full color brightness to the 800cd / m2 or more, outdoor brightness full color to the 1500cd / m2 or more, to ensure the normal operation of the display, otherwise it will be too low and can not see because of the brightness of the displayed image. The size of the brightness of the LED lamp bead is good or bad decision.
LED directly determines the size of the viewing angle of the display how much of the audience, and therefore the bigger the better. The size of the viewing angle from the die is encapsulated to decide.
Fourth, the color reduction.
Color reduction refers to the color LED display for color reduction, both the LED display to be highly consistent with the color of the playback source, so as to ensure realistic images.
Fifth, the flatness.
Flatness, if it is too obvious to the naked eye can see. LED display surface flatness to within ± 1mm, in order to ensure the display image is not distorted, partial raised or recessed will lead to the display viewing angle appears dead. The quality of flatness is determined mainly by the production process.
Sixth, material control.
The quality of the materials chosen play a decisive role to select high-quality raw materials at the source of the LED display good quality control. So for buyers as the study focus.
1, LED lamp high-end is the day of the subfamily sharp (chip package) Opto Silan mid-wafer (chips), LED lamps involved in the LED industry chain, especially in the domestic packaging industry more involved in the same wafer Swaziland Because of different chip packaging manufacturers made clear LED quality varies, high product packaging tube LED lights representatives billion light (Taiwan) Country star Lehman.
Prevent the PCB pin is a control circuit connected to the control system via cable main components, pin preferably with horns, not only when mounted screen cable inserted backwards causing rework and more: 2, Pin (with simple horn) can effectively prevent injuries mounted pin exposed screen and maintenance personnel.
3, LED modules mask and the bottom: the main material for plastics. Imports of high-quality materials, anti-deformation, strong resistance to environmental capacity.
4, resistors, capacitors and other components: As the saying goes unavoidably, often because the LED display switch, the capacitor also affects the quality of the protection switch time for Display Screen, the resistance is to control the display of current primary components, manufacturers have preferred brand products.
5, LED driver IC: accumulation of technology as the LED drive global leader in the LED display driver for many years ranked first in the world in the field of crown, made of domestic LED display driver over 60% of the global market share of over 50% accumulation 5024 is the most high-end LED display products to choose from.
6, power seat (enhanced): The power seat is undertaking major power line device connected to the PCB, although not decide the main aspects of LED display quality, but its rugged, conductivity properties also affect the Display Screen The life and protection.
LED display after completion of the project must be in strict accordance with the requirements of detection, early detection problem was solved in the future in order to avoid the use of unnecessary trouble for himself.
