42英寸LED背光液晶电视屏结构与电气接口技术规范

CVIA中国电子视像行业协会标准CVIA-TJ-LCD/LED-2010-0142英寸LED 背光液晶电视屏结构与电气接口技术规范(1.0版本)中国电子视像行业协会发 布目录前言 (1)1、范围 (2)2、结构部分 (2)3、电气接口部分 (4)前言本规范是中国电子视像行业协会的推荐性标准,是协会相关会员单位在组织技术研发、采购和生产过程中的主要参照标准,也推荐其他相关企业参考采用。

LED背光液晶电视屏结构与电气接口技术规范,是根据产业和市场的发展需求,由中国电子视像行业协会(简称“视像协会”)组织相关会员单位,共同制定的推荐性标准。

本规范旨在为企业提供彩色电视机用液晶显示屏在结构和电气接口参数方面的一致性,以达到降低生产成本、规范生产秩序、促进市场繁荣的目的。

本标准主要起草单位(排名不分先后):青岛海信电器股份有限公司、TCL集团股份有限公司、青岛海尔电子有限公司、创维RGB电子有限公司、四川长虹电器股份有限公司、康佳集团股份有限公司、厦门华侨电子股份有限公司、南京熊猫电子集团有限公司。

本规范的解释权和修订权属于中国电子视像行业协会。

1、范围本标准给出了42英寸LED背光液晶电视屏(以下简称为“屏”)的结构和电气接口技术规范,这些规范是根据目前中国市场上被共同认可的主流产品规范而确定。

2、结构部分12.1 底座的立柱固定位置:参照本规范附件1的3D图纸,固定底座使用M3螺孔。

屏厂家在开发新屏时,如需更改,应第一时间通知视像协会并与起草本规范的整机厂沟通,提供合适的立柱固定位置。

2.2 凸包和螺柱的孔深度规格:标称深度≥4.8mm,特殊孔规格单独标出。

2.3 屏的厚度尺寸变更时,变化值应≥1.5mm,并于第一时间通知视像协会并与起草本规范的整机厂沟通,确定出合适的厚度尺寸。

2.4 屏背面的结构布局示意图和结构尺寸简图分别见图1和图2(详细数据见附件2的PDF文档):2.4.1 屏的外形长宽尺寸:968.4 (H) x 564(V);侧边和顶部边框厚度≤16.2mm,底部边框厚度≤21.5mm。

2.4.2 LED Driver板(即Converter板),位置在图1左上角,屏厂家可根据Driver板的大小排布,但不能干涉到Driver板下面的六个凸包。

2.4.3 壁挂采用400*400的标准,四根M6螺柱高度为31mm。

2.5 屏的详细结构尺寸见附件1的3D图纸。
