Embodiment Construction

[0036] The present invention will be further described below with reference to the accompanying drawings and exemplary embodiments, wherein the same reference numerals in the accompanying drawings all refer to the same components. Also, detailed descriptions of known arts will be omitted if they are unnecessary to illustrate the features of the present invention.

[0037] The present invention provides a method for manufacturing a display panel, the flow chart of which is shown in Figure 3, and the specific steps are as follows:

[0038] S41, sequentially forming a wire and a light-emitting functional layer on the base substrate, the light-emitting functional layer covering the wire.

[0039] Specifically, wires can be formed by evaporation, sputtering, or inkjet printing, and the material of the wires is preferably metal, that is, metal wires; the luminescent functional layer is deposited on the substrate by sputtering, evaporation, etc. On, make the light-emitting functiona...

Abstract

The invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. A method for manufacturing a display panel, comprising: sequentially forming a conductive line and a light-emitting functional layer on a base substrate, the light-emitting functional layer covering the conductive line; forming a conductive channel in the light-emitting functional layer, and the conductive channel is formed by the light-emitting functional layer The side of the light-emitting functional layer away from the base substrate extends toward the wire; a cathode layer is formed on the light-emitting functional layer, and the cathode layer is connected to the conductive channel. The solution provided by the present invention forms a conductive channel by injecting conductive particles into the light-emitting functional layer, realizes the connection between the cathode and the wire, reduces the length of the wire between the cathode and the wire, and avoids the display panel caused by the excessively large wire area. touch blind area.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. 【Background technique】 [0002] With the rapid development of display technology, Organic Light Emitting Diode (OLED) has become the next generation of display due to its fast response, higher contrast, wide viewing angle, ultra-thin, low power consumption, and flexibility. The best choice for the screen. At present, the commonly used touch method for OLED products is on-cell embedded touch technology. The structure diagram of the OLED panel using this touch technology is as follows: figure 1 As shown, the touch sensing layer is prepared on the TFE packaging film, which reduces the number of touch sensing panels, the screen becomes thinner, the touch is more sensitive, and the color rendering is brighter. However, this solution cannot realize the integration of touch and display driver chips. integrated. ...
