Description

觸控面板及應用其的觸控顯示裝置 Touch panel and touch display device using the same

本發明涉及一種觸控面板及應用其的觸控顯示裝置。 The invention relates to a touch panel and a touch display device using the touch panel.

習知的一種觸控顯示裝置包括透明蓋板、顯示面板、以及位於透明蓋板和顯示面板之間的基板，基板的表面上形成有觸控電極用以感測觸控位置。基板為柔性可彎曲的，且其面積尺寸大於顯示面板的尺寸。基板包括層疊在顯示面板上的主體部以及超出顯示面板的彎折部，其中彎折部相對主體部彎折並貼附在顯示面板的側面且部分覆蓋顯示面板遠離透明蓋板的表面。通常觸控電極形成在基板的主體部上，而彎折部上不形成電極。製備所述觸控顯示裝置時，將具有觸控電極的基板貼附在顯示面板上時，容易出現貼附(偏貼)對位不准，導致將基板沒有設置觸控電極的部分空白區域貼在了顯示區，如此，顯示區大部分區域設置有觸控電極，而少量的區域沒有觸控電極，這兩種區域會觀察到明顯不同的視覺效果。 A conventional touch display device includes a transparent cover, a display panel, and a substrate between the transparent cover and the display panel, and touch electrodes are formed on the surface of the substrate to sense touch positions. The substrate is flexible and bendable, and its area size is larger than the size of the display panel. The substrate includes a main body laminated on the display panel and a bent part extending beyond the display panel, wherein the bent part is bent relative to the main body and attached to the side of the display panel and partially covers the surface of the display panel away from the transparent cover. Generally, touch electrodes are formed on the main body of the substrate, and no electrodes are formed on the bent portion. During the preparation of the touch display device, when the substrate with touch electrodes is attached to the display panel, the attachment (offset) alignment is prone to be misaligned, resulting in the attachment of a part of the blank area of the substrate where the touch electrode is not provided. In the display area, in this way, most areas of the display area are provided with touch electrodes, while a small number of areas do not have touch electrodes. Obviously different visual effects will be observed in these two areas.

鑒於此，有必要提供一種觸控面板，其包括：透光的且柔性可彎曲的基板，其包括主體部以及和由所述主體部的邊緣延伸的至少一彎折部； 觸控電極，設置在所述主體部的表面上；以及虛設電極，設置在所述彎折部的表面上，所述觸控電極和所述虛設電極均為多條金屬線交叉形成的網格狀。 In view of this, it is necessary to provide a touch panel, which includes: a light-transmissive and flexible substrate, which includes a main body and at least one bent portion extending from the edge of the main body; Touch electrodes are arranged on the surface of the main body part; and dummy electrodes are arranged on the surface of the bending part, the touch electrodes and the dummy electrodes are both grids formed by crossing a plurality of metal wires shape.

另一方面，還提供一種觸控顯示裝置，其包括顯示面板以及設置在所述顯示面板上的上述的觸控面板。 On the other hand, a touch display device is also provided, which includes a display panel and the aforementioned touch panel disposed on the display panel.

本發明實施例藉由基板的彎折部上也設置虛設電極，將觸控面板貼附在顯示面板上時，即使貼偏/貼歪了一些，由於彎折部上設置有同樣形狀、排列規律、排布密度的虛設電極，因此觀看觸控顯示區的顯示時，肉眼看到的觸控顯示區的顯示效果也是一致的，避免觸控顯示區出現明顯的視覺效果不一致的問題。 In the embodiment of the present invention, dummy electrodes are also provided on the bent portion of the substrate. When the touch panel is attached to the display panel, even if the attachment is offset/skewed, the bent portion is provided with the same shape and regular arrangement. , Dummy electrodes are arranged densely, so when viewing the display of the touch display area, the display effect of the touch display area seen by the naked eye is also consistent, avoiding the obvious inconsistency of visual effects in the touch display area.

本發明實施例藉由基板11的彎折部113上設置虛設電極60，將觸控面板10貼附在顯示面板20上時，即使貼偏/貼歪了一些(例如，彎折部113的部分貼在了觸控顯示區)，由於彎折部113上設置有同樣形狀、排列規律、排布密度的虛設電極60，因此觀看觸控顯示區的顯示時，肉眼看到的觸控顯示區的顯示效果也是一致的，不會導致觸控顯示區出現明顯的視覺效果不一致的問題。 In the embodiment of the present invention, the dummy electrode 60 is provided on the bending portion 113 of the substrate 11, so that when the touch panel 10 is attached to the display panel 20, even if the attachment is off/skewed (for example, the portion of the bending portion 113 Attached to the touch display area), because the bending part 113 is provided with dummy electrodes 60 of the same shape, regular arrangement, and arrangement density, so when viewing the display of the touch display area, the naked eye can see the difference of the touch display area. The display effect is also consistent, and will not cause obvious visual inconsistencies in the touch display area.

以上實施例僅用以說明本發明的技術方案而非限制，圖示中出現的上、下、左及右方向僅為了方便理解，儘管參照較佳實施例對本發明進行了詳細說明，本領域的普通技術人員應當理解，可以對本發明的技術方案進行修改或等同替換，而不脫離本發明技術方案的精神和範圍。 The above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. The up, down, left, and right directions shown in the figures are only for ease of understanding, although the present invention has been described in detail with reference to the preferred embodiments. A person of ordinary skill should understand that the technical solution of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solution of the present invention.
