style="font-size:14px;">1、以較快的速度用布或毛巾吸掉大量的水分,下一步烘干,注意需要斷電操作。</span> </p> <p> <span style="font-size:14px;">2、烘干屏體之后繼續(xù)通電老化,具體的操作步驟如下：</span> </p> <p> <span style="font-size:14px;">分階段操作：屏幕全白亮度為10%,通電老化時(shí)間為8-12個(gè)小時(shí)。</span> </p> <p> <span style="font-size:14px;">全白亮度為30%,時(shí)間為12小時(shí)</span> </p> <p> <span

style="font-size:14px;">a、在LED電子屏屏體進(jìn)水時(shí)應(yīng)及時(shí)做出對(duì)應(yīng)措施,不要拖延時(shí)間。</span> </p> <p> <span style="font-size:14px;">b、對(duì)進(jìn)水的屏體進(jìn)行快速烘干。</span> </p> <p> <span

style="font-size:14px;">1、風(fēng)扇散熱，燈殼內(nèi)部用長(zhǎng)壽風(fēng)扇加強(qiáng)散熱，比較常用的方法這種方法造價(jià)低、效果好。</span> </p> <p> <span style="font-size:14px;">2、利用鋁散熱鰭片，這是常見(jiàn)的散熱方式，用鋁散熱鰭片做為外殼的一部分來(lái)增加散熱面積。</span> </p> <p> <span style="font-size:14px;">3、空氣流體力學(xué)，利用燈殼外形，制造出對(duì)流空氣，這是低成本的加強(qiáng)散熱方法。</span> </p> <p> <span style="font-size:14px;">4、表面輻射散熱處理，燈殼表面做輻射散熱處理，較為簡(jiǎn)單的就是涂抹輻射散熱漆，可以將熱量用輻射方式帶離燈殼表面。</span> </p> <p> <span style="font-size:14px;">5、導(dǎo)熱散熱一體化—高導(dǎo)熱陶瓷的運(yùn)用，燈殼散熱的目的是降低LED高清顯示屏芯片的工作溫度，由于LED芯片膨脹系數(shù)和金屬導(dǎo)熱、散熱材料膨脹系數(shù)差距很大，不能將LED芯片直接焊接，以免高、低溫?zé)釕?yīng)力破壞LED顯示屏的芯片。</span> </p> <p> <span style="font-size:14px;">6、導(dǎo)熱管散熱，利用導(dǎo)熱管技術(shù)，將熱量由戶(hù)外LED顯示屏芯片導(dǎo)到外殼散熱鰭片。</span> </p> <p> <span style="font-size:14px;">7、導(dǎo)熱塑料殼，在塑料外殼注塑時(shí)填充商導(dǎo)熱材料，從而達(dá)到增加塑料外殼導(dǎo)熱、散熱能力。</span> </p><p> <span style="font-size:14px;">原材料對(duì)LED顯示屏價(jià)格的影響</span> </p> <p> <span style="font-size:14px;">在材料上從大類(lèi)分上來(lái)，可以分為進(jìn)口材料和國(guó)產(chǎn)材料。</span> </p> <p> <span style="font-size:14px;">在發(fā)光芯片方面，進(jìn)口的來(lái)源是：美國(guó)、日本、中國(guó)臺(tái)灣，還有一些國(guó)產(chǎn)芯片。每種發(fā)光芯片都有自己的優(yōu)缺點(diǎn)。長(zhǎng)期控制重點(diǎn)技術(shù)的美國(guó)和日本芯片，在類(lèi)似的壟斷中，它們的價(jià)格仍然很高。中國(guó)臺(tái)灣與大陸芯片價(jià)格相對(duì)便宜，但其性能與美國(guó)、日本芯片相比還是有一定差距。</span> </p> <p> <span style="font-size:14px;">如果在重要的場(chǎng)合使用LED戶(hù)外顯示屏，推薦使用進(jìn)口材料；除了LED芯片外，影響LED顯示屏價(jià)格的主要因素是LED驅(qū)動(dòng)IC，驅(qū)動(dòng)芯片是顯示質(zhì)量和壽命的重要因素，全彩LED戶(hù)外顯示屏必須采用恒壓恒流驅(qū)動(dòng)芯片。</span> </p>

style="font-size:14px;">1、散熱設(shè)計(jì)</span> </p> <p> <span style="font-size:14px;">LED工作時(shí)會(huì)發(fā)熱，溫度過(guò)高會(huì)影響LED的衰減速度和穩(wěn)定性，故PCB板的散熱設(shè)計(jì)、箱體的通風(fēng)散熱設(shè)計(jì)都會(huì)影響LED的表現(xiàn)。</span> </p> <p> <span style="font-size:14px;">2、混燈</span> </p> <p> <span style="font-size:14px;">同一種顏色不同亮度檔的LED需要混燈，或者按照離散規(guī)律設(shè)計(jì)的插燈圖進(jìn)行插燈，以保證整屏每種顏色亮度的一致性。此工序如果出現(xiàn)問(wèn)題，會(huì)出現(xiàn)大屏幕局部亮度不一致的現(xiàn)象，直接影響LED大屏幕的顯示效果。</span> </p> <p> <span style="font-size:14px;">3、設(shè)計(jì)電流值</span> </p> <p> <span style="font-size:14px;">LED的標(biāo)稱(chēng)電流為20mA，一般建議其使用電流為不超過(guò)標(biāo)稱(chēng)值的80%，尤其對(duì)于點(diǎn)間距很小的大屏幕，由于散熱條件不佳，還應(yīng)降低電流值。根據(jù)經(jīng)驗(yàn)，由于紅、綠、藍(lán)LED衰減速度的不一致性，有針對(duì)性地降低藍(lán)、綠LED的電流值，以保持大屏幕長(zhǎng)時(shí)間使用后白平衡的一致性。</span>
