Embodiment Construction

[0029] The present invention will be further described in detail below through specific examples.

[0030] image 3 It is a partial schematic diagram of the cathode overlapping area in the first row. The cathodes 24 in the first row are connected to lead wires, and the lead wires 25 include overlapping portions 251 , extending portions 252 and connecting portions 253 . The overlapping portion 251 is superimposedly connected with the first row of cathodes 24 , which is also referred to as overlapping. The bottom end of the overlapping portion 251 extends downwards to form an extending portion 252, that is, the lower edge of the overlapping portion is connected to the upper edge of the extending portion, and the extending portion 252 is a shape similar to a right-angled triangle, and the two right-angled sides of the similar right-angled triangle are connected with the overlapping portion respectively. The lower edge of 251 is connected with the upper edge of connecting portio...

Abstract

The invention discloses an organic light-emitting diode (OLED), a display and application thereof. Each lead of the organic light-emitting diode respectively corresponds to a line of negative electrodes; each of leads corresponding to a first line of negative electrodes and a second line of negative electrodes comprises an overlap part, a connection part and an extension part; an upper side of each of the extension parts and a lower side of each of the overlap parts are connected; each of the extension parts has a shape of a right angled triangle, and one right-angle side of the right angled triangle is connected with each of the overlap parts and the other right-angle side of the right angled triangle is connected with one of the connection parts; and the width of the first line of leads is reduced, so that the width of a screen body and the size of the OLED are reduced. The width of two side leads is saved on the two sides of the whole screen body, and other lines of leads can move inward by the width of one lead, so that the size of the manufactured screen body can be reduced. Each of the connection parts is directly connected with an integrated circuit (IC) area without bending by forming the extension parts.

Description

technical field [0001] The invention relates to an organic electroluminescent device, in particular to an improved lead structure 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 the traditional liquid crystal display, OLED display has the advantages of thin body, simple preparation process, fully cured luminescent material, and flexible device, which has attracted widespread attention. More and more OLEDs are used in the fields...
