车载显示光色控制方案，让显示更靓丽

汽车内饰显示质量对于驾驶的安全、信息交互的顺畅、观感的舒适性有着重要意义，尤其是随着汽车行业的发展，新能源汽车、辅助驾驶、无人驾驶细分领域的兴起，对汽车显示提出了更高的要求。

然而因车用环境的特殊性，对车载显示的光色性能要求高于传统显示行业，未来车载显示装置可能采用LCD、OLED、投影、透明显示或Micro LED多类技术，对光电检测设备的要求也相应提高。

车载光学检测中根据对象的不同，测试方案、评估项目也有差异。

01氛围灯检测方案

多色氛围灯是一种应用在汽车内部，用于烘托车内环境氛围的内饰灯，用户可根据需要设定氛围灯颜色、亮度，具有良好的用户体验效果。具体可分为：中控台、顶部显示、下部及四周显示。

氛围灯管控的项目：

• 亮度舒适性、均匀性
• 色度差异
• 同一车内亮度及颜色一致性

远方光电提供氛围灯研究和品质控制的检测方案：

MAT-200系列 LED模组自动测试系统集亮度分布、色度分布、光通量、光谱及颜色测试功能（根据订单要求定），尤其适合于各种车用装饰光源、灯条、氛围灯等的快速检测，自动化程度高，确保氛围灯的光色的研究和品质控制。

02显示器常规光学特性、环境光对比度性能、高低温条件下的光学性能

当前导航屏主流是LCD屏，部分高端车型仪表盘也采用了OLED屏，丰富仪表盘显示效果，提升用户体验感。

车载导航屏的评估项目：

• 显示屏常规光学特性的评价；
• 环境光对比度、环境光条件下显示屏的光学特性；
• 显示屏的温度特性；
• 显示器及材料的透射及反射性能；

远方光电DMS-1500H显示设备光学特性测量系统可自动完成所有测试，功能强大，为显示屏的研发和品质控制提供强有力的检测手段。

03汽车仪表盘、发光字符

仪表盘中大部分为单色光，且发光区域小、发光形状差别较大、亮度低、发光区域密集。这对亮度、色度、均匀度测量带来的极大的挑战。远方光电基于多年光学检测经验，提出了以下检测手段。

• 针对微小发光字符，一次取样测量整个平面的颜色、色度均匀性、亮度、亮度均匀性，CX系列成像彩色亮度计有发光区域自动提取功能，能高效精准分析发光区域内的亮度和色度均匀性。

• 针对亮度及色度要求高的测量，结合光谱分布测量，尤其对于单色光的光色测量更精确。

04车灯

远方光电可提供车用灯具产品的检测服务。

GO-HD5用于车灯、船用灯、航标灯、道路交通信号灯、回复反射器、逆反射材料等光度性能测试及质量评定。符合GB、ECE、JIS、SAE、FMVSS108联邦法规等标准测试要求。
