Embodiment Construction

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0037] In the current 4Mask DOT technology, the touch film layer is generally made directly on the TFE layer, which is divided into IL1 layer, M1 layer, IL2 layer, M2 layer, and OC layer from bottom to top. M1 / M2 are formed by touch electrodes. The metal wiring layer, the IL1 layer is used to optimize the film layer, which is beneficial to the DOT process. However, for the development of the 2Mask self-capacitance DOT structure (S-DOT), if the design of the IL1 layer is...

Abstract

The invention provides a display panel which comprises a display function layer and a touch electrode layer, and the material of the touch electrode layer comprises low-temperature curing type photosensitive silver paste. The low-temperature curing type photosensitive silver paste has the advantages of being high in drying speed, low in impedance, good in adhesion performance with the base material and high in photoetching resolution, the adhesive force between the touch electrode layer and the upper film layer and the adhesive force between the touch electrode layer and the lower film layer can be improved, the occurrence of stripping and other manufacturing process abnormalities can be effectively reduced, the manufacturing process yield is greatly improved, and the cost is reduced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel. Background technique [0002] Organic Light-Emitting Diode (OLED) display panel, also known as DOT technology (Direct On Cell Touch), integrates OLED and touch structure, and has better transmittance and bending resistance than external touch , and light and thin features, will become the future trend of flexible OLED display. This technology is to directly use a low-temperature process (T≤90°C) to make a touch structure on the OLED panel encapsulation layer (TFE), so as to realize the integration of OLED and touch structure. [0003] figure 1 It is a schematic plan view of a known DOT panel display area and the lower frame area touch wiring. The mark 01 is the display area (AA area), and the display area includes the display and touch effective areas; the mark 02 is the boundary of the packaging layer. Mark 03 is the lower boundary area, and the lowe...
