Problems solved by technology

[0008] However, in the above-mentioned OLED touch panel, the touch sensing layer still needs to be connected with the touch sensing chip TIC or the driving flexible circuit board DFPC through an additional touch flexible circuit board TFPC, and two The different flexible circuit board bonding (Bonding) process makes it difficult to further reduce the production cost of organic light-emitting diode touch panels, and needs to be improved urgently

Embodiment Construction

[0129] A specific embodiment according to the present invention is a capacitive touch panel. In practical applications, capacitive touch panels can be applied to any self-luminous display (such as organic light-emitting diode display, but not limited to) with on-cell stacking and thin film packaging technology, and can be applied to mutual capacitance Touch sensing technology and self-capacitance touch sensing technology. The touch sensing layer of the capacitive touch panel is made of conductive material, which can be disposed on or in the thin film encapsulation layer. The thin film encapsulation layer is formed by stacking at least one organic material layer and at least one inorganic material layer alternately by thin film encapsulation technology.

[0130] In this embodiment, the capacitive touch panel includes a plurality of pixels. The stacked structure of each pixel includes a substrate, a display layer, a thin film encapsulation layer and a conductive layer from bot...

Abstract

A capacitive touch panel is disclosed. The capacitive touch panel includes a plurality of pixels. A laminated structure of each pixel includes a substrate, a display layer, a thin-film encapsulation layer and a conductive layer from bottom to top. The display layer is disposed above the substrate. The thin-film encapsulation layer is disposed above the display layer with respect to the substrate.The thin-film encapsulation layer includes alternately stacked organic material layer and inorganic material layer. The conductive layer is disposed above the thin-film encapsulation layer or within the thin-film encapsulation layer. The conductive layer is electrically connected to a connection pad disposed above a non-display area of the display layer.

Description

technical field [0001] The present invention relates to displays, in particular to a capacitive touch panel. Background technique [0002] A conventional OLED touch panel includes an OLED substrate, a driving circuit layer formed on the OLED substrate, and an organic light emitting layer formed on the driving circuit layer. Since organic light-emitting materials are easily attenuated by water and oxygen, it is necessary to form an encapsulation layer on the organic light-emitting diode panel with a good ability to isolate water and oxygen. [0003] Such as figure 1 As shown, the encapsulation layer 14 may be a glass substrate, and the encapsulation process may use a laser emitter 16 in the frame area to emit laser light to cure the sealant material 18 to seal the OLED layer 12 . Since glass has a good barrier effect, the encapsulation layer 14 using glass can effectively isolate water and oxygen in the environment. However, due to the poor flexibility of glass, it is diff...
