Description

觸控裝置Touch device

本創作係有關一種觸控裝置，特別是關於一種具中空邊框的觸控裝置。The present invention relates to a touch device, and more particularly to a touch device having a hollow frame.

觸控顯示器係結合感測技術及顯示技術所形成的一種輸入/輸出裝置，普遍使用於電子裝置中，例如可攜式及手持式電子裝置。The touch display is an input/output device formed by combining sensing technology and display technology, and is commonly used in electronic devices, such as portable and handheld electronic devices.

電容式觸控面板為一種常用的觸控面板，其利用電容耦合效應以偵測觸碰位置。當手指觸碰電容式觸控面板的表面時，相應位置的電容量會受到改變，因而得以偵測到觸碰位置。A capacitive touch panel is a commonly used touch panel that utilizes a capacitive coupling effect to detect a touch position. When the finger touches the surface of the capacitive touch panel, the capacitance of the corresponding position is changed, and the touch position is detected.

第一圖顯示傳統觸控裝置1的剖面圖，其包含上殼體11及下殼體12。位於上殼體11與下殼體12所形成空間內，由下而上依序包含由液晶顯示模組（LCM）13、觸控面板（TP）14及保護膜15。根據第一圖所示的傳統觸控裝置1，為了確保上殼體11之向內延伸部110具有適當的強度，因此必須具有一定的厚度。該厚度使得上殼體11的頂面與保護膜15的頂面形成厚度落差，因而造成使用者操作時的不便或不舒服感。此外，傳統觸控裝置1的保護膜15係全面覆蓋於觸控面板14的頂面，會造成穿透率的下降，因而降低亮度、顯示對比度或觸控感應度。The first figure shows a cross-sectional view of a conventional touch device 1 including an upper housing 11 and a lower housing 12. The liquid crystal display module (LCM) 13, the touch panel (TP) 14, and the protective film 15 are sequentially disposed from the bottom to the top in the space formed by the upper casing 11 and the lower casing 12. According to the conventional touch device 1 shown in the first figure, in order to ensure that the inward extending portion 110 of the upper casing 11 has an appropriate strength, it is necessary to have a certain thickness. This thickness causes the top surface of the upper casing 11 to form a thickness difference with the top surface of the protective film 15, thereby causing inconvenience or discomfort in the user's operation. In addition, the protective film 15 of the conventional touch device 1 covers the top surface of the touch panel 14 in a comprehensive manner, which causes a decrease in transmittance, thereby reducing brightness, display contrast, or touch sensitivity.

第二圖顯示另一種傳統觸控裝置2的剖面圖，其包含上殼體21及下殼體22。位於上殼體21與下殼體22所形成空間內，由下而上依序包含由液晶顯示模組（LCM）23及觸控面板24。其中，觸控面板24由上而下依序包含玻璃基板241、黑色矩陣（BM）242及觸控感應層243。由於黑色矩陣（BM）242的製程良率無法達到很高，因此造成成本的上升。The second figure shows a cross-sectional view of another conventional touch device 2 including an upper housing 21 and a lower housing 22. The liquid crystal display module (LCM) 23 and the touch panel 24 are sequentially disposed from bottom to top in a space formed by the upper casing 21 and the lower casing 22. The touch panel 24 includes a glass substrate 241, a black matrix (BM) 242, and a touch sensing layer 243 from top to bottom. Since the processing yield of the black matrix (BM) 242 cannot be made high, the cost is increased.

鑑於傳統觸控裝置具有操作不便、穿透率低及良率低等缺點，因此亟需提出一種新穎的觸控裝置，用以改善傳統觸控裝置的缺點。In view of the inconveniences of conventional touch devices, low transmittance, and low yield, it is desirable to provide a novel touch device for improving the shortcomings of conventional touch devices.

鑑於上述，本創作實施例提出一種觸控裝置，其覆蓋中空的邊框於觸控面板與上殼體，且可省略黑色矩陣，因而得以提高操作便利性、穿透率、良率或排版率。In view of the above, the present invention proposes a touch device that covers a hollow frame on the touch panel and the upper case, and can omit the black matrix, thereby improving the ease of operation, the transmittance, the yield, or the layout rate.

根據本創作實施例，觸控裝置包含上殼體、下殼體、觸控面板及中空的邊框。上殼體及下殼體定義出一個容置空間。觸控面板的側面鄰接於上殼體。中空的邊框跨設於觸控面板的頂面與上殼體的頂面之間鄰接處的兩邊。According to the present embodiment, the touch device includes an upper casing, a lower casing, a touch panel, and a hollow frame. The upper and lower housings define an accommodation space. The side of the touch panel is adjacent to the upper case. The hollow frame spans both sides of the abutment between the top surface of the touch panel and the top surface of the upper casing.

第三A圖顯示本創作實施例之觸控裝置3的剖面圖，第三B圖則顯示其上視圖。在本實施例中，觸控裝置3包含上殼體31及下殼體32。在本說明書中，方向“上”或“頂面”係指向觸控裝置3的觸控面，而方向“下”或“底面”則是背向觸控裝置3的觸控面。前述上殼體31及下殼體32定義出一個容置空間，用以容置顯示模組33（例如液晶顯示模組（LCM））或其他電路（例如電源電路（未顯示於圖式中））。本實施例之顯示模組33可使用各種現有的或將來發展出來的顯示模組結構。【00010】觸控裝置3還包含觸控面板（TP）34，例如電容式觸控面板，設於顯示模組33的上方。觸控面板34的側面鄰接於上殼體31。以第三A/三B圖所示為例，觸控面板34的側面於鄰接處340鄰接於上殼體31的向內延伸部310，並使得觸控面板34的頂面與上殼體31的至少一部分頂面（例如向內延伸部310的頂面）實質位於相同平面。【00011】本實施例之觸控面板34可使用各種現有的或將來發展出來的觸控面板結構。在一實施例中，如第四圖所示之觸控面板34的剖面示意圖，觸控面板34由上而下主要包含有透明基板341及觸控感應層342，其中觸控感應層342係鍍膜於透明基板341的底面。由透明基板341及觸控感應層342所形成的觸控面板34，一般又稱為單片玻璃式（one glass solution, OGS）觸控面板。在一實施例中，觸控感應層342的底面還可再加設覆蓋層343。上述透明基板341及覆蓋層343的材質可為高透光率的絕緣材料，例如玻璃、聚碳酸酯（Polycarbonate, PC）、聚對苯二甲酸乙二酯（Polyethylene terephthalate, PET）、聚甲基丙烯酸甲酯（Polymethyl methacrylate, PMMA）或環烯烴共聚合物（Cyclic olefin copolymer, COC）。觸控感應層342的材質可為透明導電材料，例如氧化銦錫（ITO）或氧化銦鋅（IZO），但不限定於此。【00012】根據本創作的特徵之一，觸控裝置3包含邊框35，跨設於觸控面板34頂面與上殼體31頂面之間的鄰接處340兩邊。邊框35的形成可使用印刷、鍍膜或其他適當技術。本實施例之邊框35係為中空的邊框，該邊框35可為密閉型的邊框，也可為開放型的邊框。邊框35的材質可為聚對苯二甲酸乙二酯（Polyethylene terephthalate, PET）、聚碳酸酯（Polycarbonate, PC）、聚甲基丙烯酸甲酯（Polymethyl methacrylate, PMMA）或其他絕緣材料。在一實施例中，邊框35係作為一種裝飾膜（decorationfilm），其可藉由摻雜其他顏料以形成所需顏色及圖案。在本實施例中，觸控面板34被邊框35覆蓋的區域可作為觸控面板34的走線部，而未被邊框35覆蓋的區域（亦即位於邊框35的中空區域）則可作為觸控面板34的感應部。【00013】相較於傳統的觸控裝置，本實施例具有至少以下的特徵。由於本實施例之邊框35具有中空區域，因此沒有傳統之全面覆蓋保護膜（例如第一圖）所產生的穿透率下降問題。此外，由於本實施例之邊框35具有遮蔽功能（用以遮蔽觸控面板34的走線部），因此可以省略傳統觸控面板（例如第二圖）之黑色矩陣（BM），因此沒有傳統觸控面板之良率與排版率較低的問題。再者，由於本實施例之上殼體31的部分頂面與觸控面板34的頂面實質上位於相同平面，且邊框35的厚度可以做得很薄，因此使用者在操作觸控裝置3時，不會有傳統觸控裝置（例如第一圖）的上殼體頂面與觸控面板頂面因厚度落差所造成的不便。此外，本創作實施例之排版率（亦即，一片透明基板341可排列切割出的觸控面板34的數目）可大於第二圖所示傳統觸控裝置2的排版率。【00014】以上所述僅為本創作之較佳實施例而已，並非用以限定本創作之申請專利範圍；凡其它未脫離創作所揭示之精神下所完成之等效改變或修飾，均應包含在下述之申請專利範圍內。3A shows a cross-sectional view of the touch device 3 of the present embodiment, and a third B shows a top view thereof.
