Description
本創作係關於用於電容式觸控面板的電容感測器,特別是關於金屬細線構成電極的電容感測器。
習知觸控面板在成列的感應電極之間形成虛設電極,虛設電極不與感應電極導通,而是電性獨立,如此可降低感應電極之間的寄生電容,從而防止相鄰的感應電極彼此在高頻驅動時發生短路。
但是由於虛設電極必須具有很多的斷線部份,這完全與感應電極的連續(不斷線)導線圖案不同,當背光光源的光線通過虛設電極與感應電極時,光線因為被設電極與感應電極遮蔽程度不均,最後導致於人眼觀察到顯示畫面明暗不均的現象。
本創作的創作人有鑑於習知觸控面板的缺失,因而亟思改良乃創作出一種電容感測器,以解決所述習知缺失。
本創作目的係提供一種電容感測器,能夠達成電容式觸控面板更為亮度均勻一致畫面的效果。
為了達成本創作上述目的,本創作提供一種電容感測器,係用於電容式觸控面板,包括:複數條第一電極,其中該每條第一電極係分
別具有一第一導線部;複數條第二電極,係設置於該些第一電極的下方,並且與該些第一電極絕緣相交,以及該每條第二電極係分別具有一第二導線部;複數條虛設電極,其中該每條虛設電極係設置於對應的該每兩條第一電極之間,並且與該對應每兩條第一電極分別間隔開,以及其中該每條虛設電極係包含:複數個連續部與複數個斷線部,其中該每個斷線部係與該第二電極對應的該第二導線部相重疊,且該每個斷線部的寬度係小於或等於該對應的第二導線部的寬度。
茲為使 貴審查委員對本創作之技術特徵及所達成之功效有更進一步之瞭解與認識,謹佐以較佳之實施例圖並配合詳細之說明,說明如後:
10‧‧‧電容感測器
11‧‧‧第一電極
11a‧‧‧第一導線部
13‧‧‧第二電極
13b‧‧‧第二導線部
15‧‧‧虛設電極
17‧‧‧透明基板
15a‧‧‧連續部
15b‧‧‧斷線部
第1圖顯示本創作電容感測器的結構圖。
第2圖顯示本創作電容感測器的第二電極與虛設電極的結構圖。
第3圖顯示第2圖的局部放大的結構圖。
請參見第1~3圖,本創作的電容感測器10乃應用在電容式觸控面板,電容感測器10乃包括:複數條第一電極11、複數條第二電極13、以及複數條虛設電極15,茲分別說明如下內文。該些第一電極11、該些第二電極13、以及該些虛設電極15可設置於透明基板17,例如將該些第一電極11與該些虛設電極15係形成在透明基板5的上表面,而該些第二電極13 5a,而該些第二電極33係形成在透明基板5的下表面。由於透
明基板5的材質係電性絕緣材質,因此將該些第一電極11絕緣於該些第二電極,同樣地也將該些虛設電極15絕緣於該些第二電極13。
每條第一電極11乃具有第一導線部11a,而第一導線部11a的具體實施例,乃可採行為網狀導電性金屬細線。每條第二電極13乃設置於該些第一電極11的下方,並且與該些第一電極11絕緣,以及,每條第二電極乃具有第二導線部13a,而第二導線部13a的具體實施例,乃可採行為網狀導電性金屬細線。每條第一電極11朝向透明基板17的第一方向設置,而每條第二電極13朝向透明基板17的第二方向設置,而第一方向與第二方向不是採行彼此平行方向,因此,每條第一電極11係會與該些第二電極13絕緣相交。例如第一方向與第二方向是採行彼此正交方向,則每條第一電極11係會與該些第二電極13絕緣正交。第一導線部11a與第二導線部13a可採行相同網狀導電性金屬細線的結構。
第一導線部11a與第二導線部13a的網狀導電性金屬細線的材質,可採行為銅、鋁、鎳、鐵、金、銀、不鏽鋼、鎢、鉻、鈦及其合金其中之一。網狀導電性金屬細線的線條形狀,可採行為直線或弧線。
每條虛設電極15乃設置每兩條第一電極11之間,並且每條虛設電極15將該兩條第一電極11分別間隔開來。每條虛設電極15係包含:複數個連續部15a與複數個斷線部15b。連續部15a的具體實施例,可採行兩條交叉的導電性金屬細線,例如是呈十字形或X字形。所述兩條交叉的導電性金屬細線的材質,可採行為銅、鋁、鎳、鐵、金、銀、不鏽鋼、鎢、鉻、鈦及其合金其中之一。所述兩條交叉的導電性金屬細線的線條形狀,可採行為直線或弧線。
每個斷線部15b乃與第二電極13對應的第二導線部13a相重疊,並且每個斷線部15b的寬度W1
係小於或等於對應的第二導線部13b的寬度W2
。由於每個斷線部15b可被位於下方的第二導線部13b所遮蔽,因此,電容式觸控面板的背光光源的光線先會被第二導線部13b遮蔽擋下,背光光源的光線也就不可能會通過每個斷線部15b,如此而提供了電容式觸控面板更為亮度均勻一致的畫面。
上下相鄰的連續部15a與左右相鄰的連續部15a都會被斷線部15b分離且間隔著一預定距離,斷線部15b可直接利用透明基板5來形成,如此使得每個連續部15a都不會連接於上下相鄰與左右相鄰的另個連續部15a。
本創作的電容感測器10由於對虛設電極15做出改良,使得每個斷線部15b可被位於下方的第二電極13的第二導線部13b所遮蔽,而獲得電容式觸控面板更為亮度均勻一致畫面的效果,此即為本創作功效顯著增進之處。
惟以上所述者,僅為本創作之較佳實施例而已,當不能以此限定本創作實施之範圍,舉凡依創作申請專利範圍及說明內容所作之等效變化與修飾,皆仍屬本創作專利涵蓋之範圍內。
