Embodiment Construction

[0023] The present invention will be further described in detail below through specific examples.

[0024] Such as Figure 4 As shown, it is a partial schematic diagram of the overlapping area M of the OLED in the first embodiment of the present invention, and the device structure in the M area is also applicable to other overlapping areas.

[0025] The pixels 21 are evenly distributed in the display area A, the insulating layer 22 separates the left and right adjacent pixels, the spacer 23 separates the upper and lower pixels, and the cathodes are distributed in the row direction where the pixels are located. Each row of cathodes 24 is overlapped with the corresponding lead wire 25 at the bonding area 26 . The lead wire 25 includes an overlapping portion 251 and a connecting portion 252 , wherein the overlapping portion 251 overlaps with the cathode. The width of the lap is c, which is greater than the width d of the cathode. The wider lap portion increases the alignment a...

Abstract

The invention provides an organic light emitting diode (OLED) and a display as well as applications thereof. An isolating column further comprises a bending part and an extending part, wherein the extending part extends to a lead area through the bending part so as to solve the problem that a cathode and a lead can not be aligned accurately. In the OLED provided by the invention, the isolating column can limit the overlapping part of the lead within a fixed range so as to prevent the overlapping part from being overlapped by mistake, and simultaneously, the width of the overlapping part is larger than that of the cathode so as to be beneficial to the effective alignment of overlapping.

Description

technical field [0001] The invention relates to an organic electroluminescent device, in particular to a structural improvement of an organic electroluminescent device. Background technique [0002] The principle of organic electroluminescence refers to the use of organic materials as the light-emitting layer, with a cathode layer and an anode layer on both sides of the light-emitting layer, and a current is passed between the two electrodes. When the current passes through the light-emitting layer, the organic material in the light-emitting layer will emit light. Based on this principle, people have developed an organic electroluminescent device (Organic Light Emitting Diode, hereinafter referred to as OLED). Compared with traditional liquid crystal display devices, OLED has the advantages of thin body, simple preparation process, full curing of luminescent materials, and flexible devices, which has attracted widespread attention. More and more OLEDs are used in the display...
