阅读说明：本技术 发光板、线路板以及显示装置 (Light emitting panel, circuit board, and display device ) 是由 杨智超 王建 张勇 王迎姿 曲峰 秦相磊 林坚 张丽敏 孙泽鹏 唐亮珍 段智龙 于 2020-01-21 设计创作，主要内容包括：一种发光板、线路板以及显示装置。发光板包括发光单元(200)以及第一电极走线(300)。第一电极走线(300)包括第一走线(310)和第二走线(320)。发光单元(200)包括第一发光单元(2011)和第二发光单元(2012),第一发光单元(2011)所在位置为第一发光单元区,第二发光单元(2012)所在位置为第二发光单元区,第一走线(310)与第一发光单元(2011)连接,且穿过第一发光单元区且位于第二发光单元区以外,第二走线(320)与第二发光单元(2012)连接,且穿过第二发光单元区且位于第一发光单元区以外。穿过发光单元(200)所在发光单元区的第一电极走线(300)仅为与该发光单元(200)连接的第一电极走线(310),从而可以将发光单元(200)的尺寸设计的较小,以实现高密度显示或高对比度显示。(A light emitting panel, a circuit board and a display device. The light emitting panel includes a light emitting unit (200) and a first electrode trace (300). The first electrode trace (300) includes a first trace (310) and a second trace (320). The light emitting unit (200) comprises a first light emitting unit (2011) and a second light emitting unit (2012), the first light emitting unit (2011) is located in a first light emitting unit area, the second light emitting unit (2012) is located in a second light emitting unit area, the first wire (310) is connected with the first light emitting unit (2011) and penetrates through the first light emitting unit area and is located outside the second light emitting unit area, and the second wire (320) is connected with the second light emitting unit (2012) and penetrates through the second light emitting unit area and is located outside the first light emitting unit area. The first electrode wire (300) passing through the light emitting cell region where the light emitting cell (200) is located is only the first electrode wire (310) connected with the light emitting cell (200), so that the size of the light emitting cell (200) can be designed to be smaller to realize high-density display or high-contrast display.)
