Embodiment Construction

[0047] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0048] At present, LED (Light Emitting Diode, light-emitting diode) devices have received extensive attention due to their high brightness, good luminous efficiency, low power consumption, and long life.

[0049] The LED device mainly includes a light-emitting body and a pad connected to the light-emitting body. When the LED device is mounted on a display substrate, the electrodes on the display substrate need to be connected to the correspond...

Abstract

The invention provides a display substrate, a display panel and a preparation method. The display substrate comprises a first film layer, a second film layer, an electrode body and a soft conductor layer, the second film layer is arranged above the first film layer, the second film layer is provided with a through hole, and the through hole forms an opening in the side face, away from the first film layer, of the second film layer; the electrode body is arranged in the through hole; the soft conductor layer is connected with the electrode body and protrudes out of the side face, away from the first film layer, of the second film layer. The display substrate can be stably connected with an LED device, and the yield is improved.

Description

technical field [0001] The present invention and the field of display technology, in particular, relate to a display substrate, a display panel and a manufacturing method. Background technique [0002] At present, LED (Light Emitting Diode, light-emitting diode) devices have received extensive attention due to their high brightness, good luminous efficiency, low power consumption, and long life. [0003] The LED device mainly includes a light-emitting body and a pad connected to the light-emitting body. When the LED device is mounted on a display substrate, the electrodes on the display substrate need to be connected to the corresponding pads of the LED device. The display substrate provides the LED device with a working voltage and a common voltage through the electrodes, so as to drive the light-emitting body of the LED device to emit light. [0004] However, when the LED device is connected to the display substrate, since the lengths of the electrodes on the display subs...
