我曾經係兩大品牌公司lcd部門做,so可以答到你要知既問題^,^
你個既膽(paner)可能係samsung or lg 以前d 靚paner,好少有問題係因為三年前唔係個個有錢買lcd,貨要質素好至有人力推果個品牌,唔太多公司有技術去造paner,而所造的每一塊會經嚴格檢查,希望做到十全十美,改良不斷!
現在全球有7間註冊paner公司(以我所知),仲有cheap到死既台灣paner出至平paner比好多新牌子lcd公司!so唔好貪平買d唔知咩既牌子啊!!
由於電腦普及了,大多公司出招"劈價",以及低成本同埋唔浪費"有點貨",所以好多都包三點(多過三點至charge比你)
每一塊paner好難切割,而且lcd出既色同字係由一點一點光點死點砌出黎,當然..如果在切割或落貸比人唔小心大力過頭撞倒某位置時,買果陣已可見死點or光點(試mon五色,白黑紅綠藍),但philip,topcon有幾隻model包0點,but你要問清楚7day or 3 months,& 包唔包上門charge?高登有兩間最大mon shop會因為搶客即時check包0點,但要記住你要既係咩mon(要0 or good quality呀)
仲有買mon唔好以有冇包死點去買為首要條件,最緊要唔好太高brightness & sharp!要求sales比人物photo你睇,仲要較最光同最暗時人物photo會否失色得好差.
p.s~>講價喔
圖是用眼來看的,
黑色 讓你容易看到有沒光點
白色 讓你容易看到有沒暗點
三原色圖 是讓你容易看到有沒有顏色不妥的!
死點係指個mon某點顯示唔到顏色, 望上去會係黑色
光點係指個mon某點一直顯示某種顏色, 望上去通常會係紅/綠/藍
check 死點/光點時, sales會將個mon set做同一隻色, 咁你就要慢慢check清楚有冇d點係唔同顏色, check完1隻色佢就轉另1隻色比你check
通常白色時check紅點同黑點, 紅色時check藍點同綠點, 綠色時check黑點, 藍色時check紅點同綠點, 黑色時check藍點同綠點
如果間店唔比你check, 多數都係身有屎, 係黑店
死點即係果點無色
光點就係光左,或者變左色
應該無得換,不過你可以去問下
係會越來越多
係你唔好彩
不過好多 psp 都係咁
因為 psp 既質素就係咁
些液晶螢幕面板中含有缺陷的電晶體,而造成永久性的亮點與暗點。跟IC不同的是,液晶面板即使有壞點依然還是可以正常顯示,這也可以避免只是出現一些壞點而丟棄比IC面積還要大多了的液晶面板而造成浪費。面板製造商有不同的壞點診斷標準。下表是目前IBM ThinkPad筆記型電腦產品線的最大容許的壞點數。

LCD panels are more likely to have defects than most ICs due to their larger size. In this example, a 12" SVGA LCD has 8 defects and a 6" wafer has only 3 defects. However, 134 of the 137 dies on the wafer will be acceptable, whereas rejection of the LCD panel would be a 0% yield. (The standard is much higher now due to fierce competition between manufacturers and improved quality control. An LCD panel with 4 defective pixels is usually considered defective and customers can request an exchange for a new one.) The location of a defective pixel is also important. Often manufacturers relax their requirements when defective pixels are in the center of the viewing area.
