Standard for customers to choose high quality LED display screen

У апошнія гады, LED display screen is widely used in various fields such as indication, display, decoration, backlight, general lighting and urban night scene. It can be roughly divided into: indoor LED display, outdoor LED display, commercial LED advertising screen, led creative screen, stadium LED screen, LED floor tile screen, LED color screen, г.д.

different companies focus on different sales strategies. Some companies focus on price war, materials, performance, quality are often unsatisfactory, do not covet cheap, buy some substandard low-quality products, regret.

So how can consumers choose a product that they are satisfied with in the complicated environment of LED display industry? The following LED display factory will briefly summarize several points for you as your reference for screening: the most important component of

LED display screen is led device. The general selection criteria are: высокая яркасць, low operating voltage, нізкае энергаспажыванне, large-scale, доўгае жыццё, impact resistance and stable performance. Failure rate
refers to the failure rate of LED display screen from the beginning of assembly to 72 hours aging, and the failure rate shall not be higher than 3 / 10000 (refers to the failure caused by LED device itself)

2 2 LED is a semiconductor device, which is sensitive to static electricity and easily leads to static failure. Таму, antistatic ability is very important to the life of display screen. Наогул кажучы, the failure voltage of LED human body electrostatic mode test should not be lower than 2000V.

3. Пляскатасць
LED display surface flatness should be within 0, каб пераканацца, што малюнак на дысплеі не будзе скажацца. Лакальная выпукласць або ўвагнутасць прывядзе да мёртвага кута экрана дысплея.

4. Яркасць і кут агляду
the brightness of indoor full-color LED display screen should be above 800 CD / м2, and outdoor full-color LED display screen should be above 1500? CD / м2, такім чынам, каб забяспечыць нармальнае адлюстраванне экрана святлодыёднага дысплея, otherwise, the brightness will be too low to see the displayed image. If the environment is very bright, please give priority to LED or rear projection. The brightness is mainly determined by the quality of LED tube core? The size of

visual angle directly determines the visible area space of LED display, таму чым больш, тым лепш. Памер кута агляду ў асноўным вызначаецца святлодыёдным чыпам.

5. Эфект балансу белага
white balance effect is one of the most important indicators of LED display. У каляровасці, пры суадносінах чырв, green and blue is 1:4.6:0.16, будзе адлюстроўвацца чысты белы колер. Калі фактычная прапорцыя мае невялікае адхіленне, there will be a deviation of white balance. Якасць балансу белага ў асноўным вызначаюць святлодыёдныя чыпы, і святлодыёдныя чыпы таксама ўплываюць на змяншэнне колеру.

6. Рэдуктыўнасць колеру
color reducibility refers to the color restoration of LED display screen, гэта, the color displayed on LED display screen should be highly consistent with the color of the playback source, каб пераканацца ў сапраўднасці выявы.

7. Whether there are mosaics or dead spots?
mosaics refer to the small four squares which are always bright or black on the LED display screen, што з'яўляецца з'явай модульнага некрозу. The number of dead point is mainly determined by the quality of LED chip. А 6032 a 6032 8. With or without color block a 6032 color block refers to the lack of color in a small area; асноўная прычына - кантраляваць мікрасхему і блок харчавання, control the quality of circuit layout.

9. The appearance of LED display screen
LED display screen appearance is the most intuitive, the most original to do the most preliminary evaluation of product quality. The appearance quality can reflect the production process and material quality of LED display screen manufacturer.
