Description

发光基板及显示装置 技术领域
本申请涉及显示技术领域，具体涉及一种发光基板及显示装置。
 背景技术
次毫米发光二极管，最早由我国台湾公司晶元光电提出，指由晶粒(芯片)尺寸在50微米至200微米的发光二极管构成的显示屏，介于微型发光二极管和小间距显示之间。应用方向包括次毫米发光二极管直显和次毫米发光二极管背光的显示屏。由于次毫米发光二极管显示屏在能耗、色域、对比度、柔性、寿命等方面都有较为出色的表现，工艺难度又没有微型发光二极管那么大，制作成品相对容易，因此次毫米发光二极管有望成为液晶显示屏升级的主导产品，与有机发光二极管显示屏在消费市场一较高下。
采用次毫米发光二极管技术的屏幕还拥有长寿命、不易烧屏等优势，实现规模量产后成本还会比有机发光二极管显示屏屏幕更低。当然毫米发光二极管技术也有缺点，因为集成更多的发光单元，发光单元的分区越多，用于电性连接发光单元的信号线则越多，对应的用于传输信号的端口也越多，进而使得产品的成本较高。
因而，如何减少信号传输端口，以降低产品生产成本是亟需解决的问题。
