Description
本發明是有關於一種顯示面板，且特別是有關於一種觸控顯示面板(touch display panel)。 The present invention relates to a display panel, and more particularly to a touch display panel.
觸控面板依照其感測方式的不同而大致上區分為電阻式觸控面板、電容式觸控面板、光學式觸控面板、聲波式觸控面板以及電磁式觸控面板。由於電容式觸控面板具有反應時間快、可靠度佳以及耐用度高等優點，因此，電容式觸控面板已被廣泛地使用於電子產品中。依照結構及製造方式的不同，電容式觸控面板又可大致上區分為外貼式(added-on type)與整合式/內建式(on-cell/in-cell type)兩種。外貼式的電容式觸控面板通常是先將感測串列先製作於一輔助基板上，再將此已製作有感測串列的輔助基板貼附於顯示器的外表面上，外貼式觸控面板具有廣泛的應用。 The touch panel is roughly classified into a resistive touch panel, a capacitive touch panel, an optical touch panel, an acoustic wave touch panel, and an electromagnetic touch panel according to different sensing methods. Capacitive touch panels have been widely used in electronic products because of their fast response time, high reliability, and high durability. Depending on the structure and manufacturing method, the capacitive touch panel can be roughly divided into an additive-on type and an on-cell/in-cell type. The externally mounted capacitive touch panel usually firstly forms the sensing series on an auxiliary substrate, and then attaches the auxiliary substrate on which the sensing series has been fabricated to the outer surface of the display. Touch panels have a wide range of applications.

Referring to FIG. 7 , the touch display panel 600 of the sixth embodiment is substantially the same as the touch display panel 400 of the fourth embodiment, except that the display panel 640 is, for example, an organic light emitting display panel. The display panel 640 includes a first electrode 642, a second electrode 644, and an active layer 646. The first electrode 642 and the second electrode 644 are disposed opposite to each other, and the active layer 646 is located between the first electrode 642 and the second electrode 644. The active layer 646 includes an organic light emitting layer. According to the embodiment, the touch display panel 600 does not include Polarizer and backlight module. Moreover, the touch display panel 600 of the present embodiment can simultaneously have the effects of polarized light and explosion-proof through the arrangement of the explosion-proof film 620 having a polarizing effect.
綜上所述，本發明將偏光片貼附在觸控面板上以發揮防爆的功效，並同時具有偏振光線的功效，如此一來，觸控顯示面板可以減少一道防爆膜的設置。或者，本發明也可以將具有偏光效果的防爆膜設置在觸控面板以及顯示面板之間，以同時發揮防爆以及偏振光線的功效，以減少一道偏光片的設置。據此，本發明之觸控顯示面板的製程得以簡化，而具有較佳的良率以及較低的製作成本。 In summary, the present invention attaches a polarizer to a touch panel to exert an explosion-proof effect and at the same time has the effect of polarizing light, so that the touch display panel can reduce the setting of an explosion-proof film. Alternatively, the present invention can also provide an explosion-proof film having a polarizing effect between the touch panel and the display panel to simultaneously exert the effects of explosion-proof and polarized light to reduce the setting of one polarizer. Accordingly, the process of the touch display panel of the present invention is simplified, and has better yield and lower manufacturing cost.
雖然本發明已以實施例揭露如上，然其並非用以限定本發明，任何所屬技術領域中具有通常知識者，在不脫離本發明之精神和範圍內，當可作些許之更動與潤飾，故本發明之保護範圍當視後附之申請專利範圍所界定者為準。 Although the present invention has been disclosed in the above embodiments, it is not intended to limit the invention, and any one of ordinary skill in the art can make some modifications and refinements without departing from the spirit and scope of the invention. The scope of the invention is defined by the scope of the appended claims.
