Embodiment Construction

[0059] Figure 1A It is a schematic cross-sectional view of a touch display panel according to an embodiment of the present invention. Figure 1B for Figure 1A A schematic top view of the touch sensing electrodes. Please refer to Figure 1A , in this embodiment, the touch display panel 100 a includes a driving array substrate 110 , a facing substrate 120 a , an organic light emitting diode structure 130 a , a plurality of conductive spacers 140 and a sealant 150 .

[0060] In detail, the driving array substrate 110 is, for example, an active device array substrate, which includes a substrate 112 and a plurality of active devices 114 . Each active element 114 is, for example, composed of a gate G, a gate insulating layer GI, a channel layer C, a source S, a drain D and an insulating layer I, wherein the gate G is located on the substrate 112, The gate insulating layer GI, the channel layer C, the source S / drain D and the insulating layer I are sequentially stacked on the subs...

Abstract

A touch display panel including a array substrate, an opposite substrate, an organic light emitting diode (OLED) structure, a plurality of conductive spacers and a sealant is provided. The OLED structure is disposed on the opposite substrate and located between the array substrate and the opposite substrate. The OLED structure includes a first electrode layer, an organic light emitting layer and a second electrode layer which are sequentially disposed. The first electrode layer is located on the opposite substrate and includes a plurality of touch sensing electrode. The second electrode layer is electrically connected to the array substrate via the conductive spacers. The sealant is sealed the OLED structure and the conductive spacers between the array substrate and the opposite substrate.

Description

technical field [0001] The present invention relates to a touch display panel, and in particular to a touch display panel using an organic light-emitting layer for display. Background technique [0002] The current common touch display device is a display panel plus an external touch panel, so it has relatively high thickness and weight, and the design of the additional touch panel is likely to cause the attenuation of the transmittance. Therefore, if the touch function can be directly integrated into a display device, the above problems can be effectively avoided. Contents of the invention [0003] The present invention provides a touch display panel, which uses an organic light emitting diode structure for display, and the first electrode layer of the organic light emitting diode structure includes a touch sensing electrode, so the touch display panel can be combined without greatly increasing its thickness. With touch and display functions. [0004] The present invent...
