The substrate 110 can be a hard substrate, such as a glass substrate, or the substrate 110 can be a flexible substrate, such as a plastic substrate. In general, in order to allow light to be transmitted through the substrate 110, =110 it is often a transparent material. However, this creation is not limited to this. v The right organic light emitting diode structure is designed to be a single-sided light-emitting type, and a non-transparent material substrate can also be used. Hereinafter, only one organic light-emitting diode junction will be described in detail for convenience of explanation. = In detail, the first conductive layer 120 has been placed on the substrate unit 110a with a cup _ L-shaped opening σ 122, wherein the L-shaped opening 122 exposes a portion of the base to divide the first conductive layer (10) into a first conductive region. Conductive block 126. In the present embodiment, the area of the first conductive region 7 etch block 882 is larger than the area of the second conductive block 126, and the second conductive block 126 is located at a corner of the substrate unit u 〇 a. Here, the first conductive layer 120 functions as an anode. The organic light-emitting layer 130 is disposed on the first conductive layer 12, and covers the portion L-shaped opening 122 and a portion of the first conductive block 124. In particular, the organic light-emitting layer 13 of the present embodiment does not cover the second conductive block 126 and exposes a first portion 127 of the first conductive block 124 and a second portion 129', wherein the first conductive block i26 is located at the first A portion 127 is between the second portion 129. Here, at least one of the first portion 127 and the second portion 129 of the first conductive block 124 exposed by the organic light-emitting layer 13 is adapted to be electrically connected to a positive voltage source V1. Further, the shape of the organic light-emitting layer 13A is, for example, a rectangle. The second conductive layer 14 is disposed on the organic light-emitting layer ι3 and covers a portion of the organic light-emitting layer 130. In particular, the second conductive layer 14A of the present embodiment has a protruding portion 142' and the protruding portion 142 covers a portion of the second conductive block 126. The first conductive layer 14 is adjacent to both sides of the adjacent protruding portion 142. Light emitting layer 13G. That is, the second conductive layer 14A of the present embodiment does not completely cover the organic light-emitting layer 130. Further, a portion where the second conductive layer 14A, the organic light-emitting layer 130, and the first conductive layer 12 are overlapped is defined as a light-emitting region S. As shown in Fig. 1, these organic light-emitting diode structures can constitute an organic light-emitting diode module 1G, and the organic light-emitting diode module 1 has four light-emitting regions s. In particular, the second 140 herein is a cathode and the region of the second conductive block 126 that is not covered by the protrusions is adapted to be electrically connected to the negative voltage source V2. M416882 In this embodiment, at least one of the first conductive layer 120 and the second conductive layer 14 is a transparent conductive layer, and the materials of the first conductive layer 120 and the second conductive layer 140 include indium tin oxide, aluminum, magnesium. Or silver. For example, the organic light emitting diode structure 100 is mainly composed of a first conductive layer 12 (i.e., an anode), an organic light emitting layer 13A, and a second conductive layer 14 (i.e., a cathode). If the first conductive layer 120 and the second conductive layer 140 are respectively a transparent conductive layer and a thin metal layer, the formed organic light emitting diode structure 100 is a double-sided light emitting device. If the first conductive layer 12 is a transparent conductive layer, the formed organic light emitting diode structure 1 is a bottom light emitting organic light emitting diode structure; if the second conductive layer 14 is a transparent conductive layer, Then, the formed organic light-emitting diode structure is a top-emitting organic light-emitting diode structure. Further, the organic light emitting layer 130 may be a small molecule organic light emitting material or a high molecular organic light emitting material. Since the embodiment is to change the contact position of the positive voltage source VI and the negative voltage source V2 through the pattern design of the first conductive layer 12, the organic material layer 13 and the second conductive layer 140, wherein the positive voltage source V1 is connected The dot position is that the first portion U7 and the second portion 129' of the first conductive block 124 are exposed by the organic light-emitting layer 130, and the contact position of the negative voltage source V2 is that the first conductive block 126 is not the second conductive layer 14 The area covered by the protrusion 142. This design can receive a stable voltage at every place of the organic light-emitting layer 13〇, thereby avoiding the voltage drop caused by the difference in the path of the current flowing through the current, so that the organic light-emitting layer 13 is acceptable. The voltage not f' causes a problem that the luminous efficacy of the organic light-emitting layer U0 is different. In other words, the organic light-emitting diode structure of the present embodiment may be 9 degrees for each place. : 疋 电 ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ The contact position of the voltage source and the negative voltage source.
