Description

LED面板顯示器結構
一種LED面板顯示器結構，尤指一種僅透過單一控制芯片即可控制複數發光二極體元件，藉此達到節省成本及實現提升單位解析度的LED面板顯示器結構。
液晶顯示器訊號掃描方式為一次一列，並且逐列而下。Gate Driver IC連結至電晶體之Gate端，負責每一列電晶體的開關，掃描時一次打開一整列的電晶體。當電晶體打開(ON)時，Source Driver IC才能夠逐行將控制亮度、灰階、色彩的控制電壓透過電晶體Source端、Drain端形成的通道進入Panel的畫素中。因為Gate Driver IC負責每列電晶體的開關，所以又稱為Row Driver或Scan Driver。當Gate Driver逐列動作時，Source Driver IC負責在每一列中將資料電壓逐行輸入，因此又稱為Column Driver或Data Driver。
以SXGA為例，解析度為1,280 x 1,024，意思為有效顯示區間之畫素矩陣共有1,280行與1,024列，由於單一畫素要呈現彩色則必須包括R、G、B三原色，因此SXGA必須要有1,280 x 3=3,072個Column data。如果Gate Driver IC腳數為256pin，Source Driver IC腳數為384pin，要驅動SXGA的液晶顯示面板則需要1,024/256=4顆Gate Driver IC與1,280 x3/384=10顆Source Driver IC。以相同腳數之驅動IC來驅動XGA(1,024 x 768)，則需要3顆Gate Driver IC與8顆Source Driver IC，這是目前最常用的組合。
即表示若解析度越高則所需的驅動IC則需要越多，在有限的單位面積中則無法設置如此多的驅動IC，如此無法實現小面積高解析度之顯示器。
爰此，為解決上述習知技術之缺點，本發明之主要目的，係提供一種可降低生產成本及透過單一控制芯片控制整體LED面板顯示器藉以實現小面積面板，高解析度的LED面板顯示器結構。
為達上述之目的，本發明係提供一種LED面板顯示器結構，係包含：一基部、一第一電極層、一第二電極層、複數開關元件、複數發光二極體元件、一控制芯片；所述基部具有一第一側及一第二側；該第一電極層具有複數第一電極線路縱向延伸設置於前述基部之第一側；該第二電極層具有複數第二電極線路橫向延伸設置於前述基部之第一側，並與前述第一電極線路相互跨接。
該等開關元件設置於前述基部之第一側，該等開關元件具有一第一接腳及一第二接腳及一第三接腳，該第一、二接腳分別與前述第一、二電極線路電性連接。
該等發光二極體元件設置於前述基部之第一側，該等發光二極體元件具有一第一腳位及一第二腳位，該第一腳位與前述第三接腳電性連接，該第二腳位與一接地端電性連接。
該控制芯片與前述第一、二電極層電性連接。
透過本發明LED面板顯示器結構，使用單一控制芯片控制LED面板顯示器整體係大幅降低生產製造成本，並且因透過整合LED面板顯示器整體之發光二極體元件之控制由單一控制芯片控制，進而省略複數控制芯片之設置，令小面積面板中具有高解析度之顯示效能並同時具有觸控與指紋辨識功能得以實現。
