<span style="font-size:14px;">1.檢查顯示器與顯卡的連線是否松動(dòng)。接觸不良導(dǎo)致出現(xiàn)"雜波"、"雜點(diǎn)"狀的花屏是常見(jiàn)的現(xiàn)象。</span> </p> <p> <span style="font-size:14px;">2.檢查顯卡是否過(guò)度超頻，昆明室內(nèi)P4全彩屏。若顯卡過(guò)度超頻使用，一般會(huì)出現(xiàn)不規(guī)則、間斷的橫紋。這時(shí)，昆明室內(nèi)P4全彩屏，應(yīng)該適當(dāng)降低超頻幅度。注意，首先要降低顯存頻率。</span> </p> <p> <span style="font-size:14px;">3.檢查顯卡的質(zhì)量。若是更換顯卡后出現(xiàn)花屏的問(wèn)題，且在使用一、二招未能奏效后，則應(yīng)檢查顯卡的抗電磁干擾和電磁屏蔽質(zhì)量是否過(guò)關(guān)。具體辦法是：將一些可能產(chǎn)生電磁干擾的部件盡量遠(yuǎn)離顯卡安裝(如硬盤(pán))，再看花屏是否消失。若確定是顯卡的電磁屏蔽功能不過(guò)關(guān)，則應(yīng)更換顯卡，昆明室內(nèi)P4全彩屏，或自制屏蔽罩。</span> </p> <p> <span style="font-size:14px;">4.檢查顯示器的分辨率或刷新率是否設(shè)置過(guò)高。液晶顯示器的分辨率一般低于CRT顯示器，若超過(guò)廠家推薦的分辨率，則有可能出現(xiàn)花屏的現(xiàn)象。</span> </p> <p> <span style="font-size:14px;">5.檢查是否安裝了不兼容的顯卡驅(qū)動(dòng)程序。這種情況一般容易被忽視，因?yàn)轱@卡驅(qū)動(dòng)程序的更新速度越來(lái)越快(尤其是NVIDIA顯卡)，有些用戶(hù)總是迫不及待地安裝新版本的驅(qū)動(dòng)。</span> </p> <p> <br />

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> 昆明P3全彩電子屏價(jià)格LED顯示屏應(yīng)該如何做好防火工作？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="昆明室內(nèi)P4全彩屏,全彩" src="https://tyunfile.71360.com/WaterMark/UploadFile/qichuang2020/637384652174012221/2604279.png"></div><p> L<span style="font-size:14px;">ED顯示屏如何對(duì)付高溫考驗(yàn)？</span> </p> <p> <span style="font-size:14px;">1.選料</span> </p> <p> <span style="font-size:14px;">LED顯示屏由面具、線路板、底殼構(gòu)成，為防火安全防水LED顯示屏應(yīng)用的防水密封膠也是LED顯示屏關(guān)鍵的構(gòu)成部分。其面具和底殼所有選用根據(jù)品質(zhì)認(rèn)證的具備阻燃性作用的PC玻璃纖維原材料。線路板則噴灰黑色的三防漆，避免風(fēng)化層、浸蝕等。</span> </p> <p> <span style="font-size:14px;">2.處理排熱難題</span> </p> <p> <span style="font-size:14px;">LED顯示屏總面積越大，應(yīng)用的用電量越大，發(fā)燙越明顯。加上夏天太陽(yáng)暴怒，外度溫度高造成排熱難。為處理排熱難題，應(yīng)從LED顯示屏外觀設(shè)計(jì)方案和內(nèi)部構(gòu)造開(kāi)展調(diào)節(jié)，選用鏤空雕花設(shè)計(jì)方案，密度高的高精密設(shè)計(jì)電路板。內(nèi)部選用微距鏡頭透空設(shè)計(jì)方案，不造成積雨，不造成電線短路風(fēng)險(xiǎn)。不用散熱風(fēng)扇，減少LED電源電路負(fù)載，內(nèi)外緊密結(jié)合做到效率高排熱實(shí)際效果。</span> </p> <p> <span style="font-size:14px;">3.安裝標(biāo)準(zhǔn)</span> </p> <p> <span style="font-size:14px;">LED顯示屏歸屬于大功率插座，易產(chǎn)生短路故障?？墒钦鎸?shí)品質(zhì)通關(guān)的LED顯示屏從線纜到構(gòu)造都杜決短路故障狀況。殊不知在安裝全過(guò)程中一點(diǎn)疏忽和粗心大意很有可能造成出乎意料的風(fēng)險(xiǎn)。為保證安全，必須生產(chǎn)廠家全線具體指導(dǎo)安裝，保證接對(duì)正負(fù)、保證電源電路聯(lián)接堅(jiān)固，另外消除LED顯示屏附近的易燃物品。并按時(shí)分配技術(shù)專(zhuān)業(yè)專(zhuān)業(yè)技術(shù)人員對(duì)LED顯示屏開(kāi)展檢驗(yàn)、查驗(yàn)。</span> </p><p> <span style="font-size:14px;">LED電子顯示屏照明是有條件的。在PN結(jié)上施加正向電壓會(huì)使PN結(jié)本身形成能級(jí)（實(shí)際上是一系列能級(jí)），電子在該能級(jí)上轉(zhuǎn)變并產(chǎn)生光子照射。因此，必須通過(guò)施加在PN結(jié)上的電壓來(lái)驅(qū)動(dòng)LED發(fā)光。此外，由于LED是特性敏感半導(dǎo)體器件并且具有負(fù)溫度特性，因此需要在施加過(guò)程中穩(wěn)定和保護(hù)工作狀態(tài)，從而產(chǎn)生LED的“驅(qū)動(dòng)”概念。</span> </p> <p> <span style="font-size:14px;">任何熟悉LED的人都知道LED的前向伏安特性非常陡峭（前向動(dòng)態(tài)電應(yīng)變非常小）。向LED供電更加困難。它不能像普通白熾燈那樣直接由電壓源供電。否則，電壓紋波稍微增加，電流增加到LED燃燒的程度。為了穩(wěn)定LED的工作電流并確保LED能夠正常可靠地工作，已經(jīng)出現(xiàn)了各種LED驅(qū)動(dòng)電路。</span>

style="font-size:14px;">2、屏幕大片不顯現(xiàn)，全是黑的。(先思索電源的傳輸是否有問(wèn)題，從有問(wèn)題的模組開(kāi)端盤(pán)查，或是電源開(kāi)關(guān)壞了沒(méi)有電，檢查排線是否松動(dòng)信號(hào)沒(méi)有傳輸過(guò)去，再有就是接納卡損壞問(wèn)題;逐個(gè)掃除可找到處理辦法)</span> </p> <p> <span style="font-size:14px;">3、LED顯示屏整行模組異常顯現(xiàn)，一閃一閃的并且有正色。(從有問(wèn)題的板子開(kāi)端檢查，檢查排線是無(wú)松動(dòng)、板子排線接口能否損壞，如有問(wèn)題盡早換排線或出問(wèn)題板子)</span> </p> <p> <br />
