Description
本發明是有關於一種觸控面板以及觸控顯示面板。The invention relates to a touch panel and a touch display panel.
近年來，各式電子產品都不斷朝向操作簡便、小體積以及大螢幕尺寸的方向邁進，特別是攜帶式的電子產品對於體積及螢幕尺寸的要求更為嚴格。因此，許多電子產品都將觸控面板與液晶顯示面板整合，以省略鍵盤或是操控按鍵所需的空間，進而擴大螢幕可配置的面積。In recent years, various electronic products have been moving toward simple operation, small size, and large screen size. In particular, portable electronic products have stricter requirements on volume and screen size. Therefore, many electronic products integrate the touch panel with the liquid crystal display panel to omit the space required for the keyboard or the control buttons, thereby expanding the configurable area of the screen.
目前，觸控面板大致可區分為電阻式、電容式、紅外線式及超音波式等觸控面板，其中以電阻式觸控面板與電容式觸控面板為最常見的產品。就電容式觸控面板而言，可多點觸控的特性提供更人性化的操作模式而使得電容式觸控面板受到市場的青睞。Currently, touch panels can be roughly classified into resistive, capacitive, infrared, and ultrasonic touch panels. Among them, resistive touch panels and capacitive touch panels are the most common products. In the case of a capacitive touch panel, the multi-touch feature provides a more user-friendly operation mode, and the capacitive touch panel is favored by the market.
一般而言，電容式觸控面板是藉由使用者透過手指或導電物件觸碰電容式觸控面板所造成之電容值的改變去偵測手指或導電物件的觸碰位置。進一步而言，電容式觸控面板通常具有彼此電性絕緣的第一導電層以及第二導電層，其中第一導電層以及第二導電層之間例如是藉由配置一絕緣層，來達到電性絕緣的效果。在使用者未觸碰觸控面板下，第一導電層以及第二導電層之間具有一電容初始值。而當使用者觸碰觸控面板時，被碰觸的位置會產生電容值的改變，因而改變原本的電容初始值。此時，則能藉由判 別改變的電容值之位置去判定使用者觸碰的位置。In general, a capacitive touch panel detects a touch position of a finger or a conductive object by a change in a capacitance value caused by a user touching a capacitive touch panel through a finger or a conductive object. Further, the capacitive touch panel generally has a first conductive layer and a second conductive layer electrically insulated from each other, wherein the first conductive layer and the second conductive layer are electrically connected, for example, by disposing an insulating layer. The effect of sexual insulation. The capacitor has an initial value between the first conductive layer and the second conductive layer when the user does not touch the touch panel. When the user touches the touch panel, the touched position will change the capacitance value, thus changing the original capacitance initial value. At this time, it can be judged by Do not change the position of the capacitance value to determine the position touched by the user.
第一導電層以及第二導電層通常具有多個彼此電性絕緣的感應圖案，且感應圖案間存在無感應圖案的空隙區域。由於感應圖案區以及空隙區域的折射係數不同，因此由顯示面板出射的光在通過觸控面板後，會有不同的偏折角度，而讓使用者觀看到觸控面板中感應圖案的邊緣以及感應圖案的形狀。如此，顯示畫面以及觸控面板之感應圖案的圖像重疊造成視覺上的干擾，並降低應用此觸控面板之觸控顯示面板的顯示品質。The first conductive layer and the second conductive layer generally have a plurality of sensing patterns electrically insulated from each other, and a gap region having no sensing pattern exists between the sensing patterns. Since the refractive index of the sensing pattern area and the gap area are different, the light emitted by the display panel may have different deflection angles after passing through the touch panel, and the user may view the edge of the sensing pattern in the touch panel and the sensing. The shape of the pattern. In this way, the image overlay of the display screen and the sensing pattern of the touch panel causes visual interference and reduces the display quality of the touch display panel to which the touch panel is applied.
