Problems solved by technology

[0004] The inventors found that in the existing bottom-emitting OLED, the deposition thickness of the cathode is reduced to have a certain transmittance, and the reduction of the thickness of the cathode will lead to an increase in the resistance of the cathode, thereby generating a large voltage drop (IR Drop), Make the display brightness of the OLED display panel uneven

Abstract

The embodiment of the invention provides an OLED display panel and a manufacturing method thereof and an OLED display device. The OLED display panel includes an OLED display substrate and a packagingsubstrate which are arranged relatively. The OLED display substrate comprises a first substrate, a first electrode, a second electrode and an organic luminescence layer, wherein the first electrode, the second electrode and the organic luminescence layer are arranged in sequence on the first substrate. The packaging substrate comprises a second substrate and a conductive layer disposed on the second substrate. The surface provide with the second electrode of the OLED display substrate is bonded with surface provided with the conductive layer of the packaging substrate through bonding adhesive,wherein the bonding adhesive includes conductive particles. The conductive layer is electrically connected with the second electrode by the conducting particles. The OLED display panel and the manufacturing method thereof and the OLED display device enable the conductive layer and the second electrode to be electrically connected by including the conductive particles in the bonding adhesive, theentire electrode layer includes the conductive layer and the second electrode, the resistance of the entire electrode layer is reduced, the voltage drop is reduced, and the brightness uniformity of the OLED display panel is ensured.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular to an OLED display panel, a manufacturing method thereof, and an OLED display device. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Device, referred to as OLED) display panel is a display device different from traditional liquid crystal display (Liquid Crystal Display, referred to as LCD), with active light, good temperature characteristics, low power consumption, responsive Fast, bendable, ultra-thin and low cost. Therefore, it has become one of the important development discoveries of the new generation display device, and has received more and more attention. [0003] OLED display panels can be divided into three types according to the direction of light emission: bottom-emitting OLEDs, top-emitting OLEDs, and double-sided emitting OLEDs. Wherein, the bottom emission OLED includes: an encapsulation substrate and an...
