電視墻(qiang)便能顯示清晰、色彩艷(yan)麗、高亮度(du)的(de)復雜(za)全彩多媒體(ti)圖形(xing)影像信息。是動態影像展(zhan)示、宣傳(chuan)、廣告(gao)的(de)   佳(jia)方(fang)式。大屏幕電視墻(qiang)的(de)宣傳(chuan)表達能力   強(qiang)、   、氣派、豪(hao)華，常在   、體(ti)育場館、證(zheng)券市場、調(diao)度(du)指揮等使用(yong)。  

電(dian)視(shi)(shi)(shi)(shi)墻(qiang)是(shi)由多(duo)(duo)個電(dian)視(shi)(shi)(shi)(shi)（背投電(dian)視(shi)(shi)(shi)(shi)）單元拼(pin)接(jie)而成的一種(zhong)屏(ping)幕電(dian)視(shi)(shi)(shi)(shi)墻(qiang)體，是(shi)一種(zhong)影(ying)像、圖文顯(xian)示(shi)系統(tong)。可看(kan)作是(shi)一臺可以顯(xian)示(shi)來自計算機VGA信(xin)號、多(duo)(duo)種(zhong)視(shi)(shi)(shi)(shi)頻信(xin)號的巨型顯(xian)示(shi)屏(ping)，向(xiang)電(dian)視(shi)(shi)(shi)(shi)墻(qiang)傳送視(shi)(shi)(shi)(shi)頻或者計算機VGA信(xin)號。

很多(duo)視(shi)頻監(jian)(jian)(jian)(jian)控(kong)(kong)項目采(cai)用電視(shi)墻(qiang)做為顯示(shi)設備，使(shi)用電視(shi)墻(qiang)進行監(jian)(jian)(jian)(jian)控(kong)(kong)有直觀，方便的特點，便于監(jian)(jian)(jian)(jian)控(kong)(kong)人員(yuan)實時(shi)發現被監(jian)(jian)(jian)(jian)控(kong)(kong)目標的異常狀況。監(jian)(jian)(jian)(jian)控(kong)(kong)用電視(shi)墻(qiang)一般采(cai)用   監(jian)(jian)(jian)(jian)視(shi)器作為顯示(shi)設備，配(pei)以(yi)鋼板鈑金(jin)噴塑墻(qiang)體構(gou)成，有些還(huan)帶(dai)有強制排(pai)風散熱裝(zhuang)置。在(zai)監(jian)(jian)(jian)(jian)控(kong)(kong)，由(you)于電視(shi)墻(qiang)監(jian)(jian)(jian)(jian)控(kong)(kong)只能實時(shi)監(jian)(jian)(jian)(jian)看(kan)，不能回(hui)放(fang)，因此往往需要與(yu)硬盤錄像機及視(shi)頻矩陣配(pei)合使(shi)用以(yi)形成完(wan)整的監(jian)(jian)(jian)(jian)控(kong)(kong)系統。
