摘　　要：Local dimming(局部调光)是一种低成本提升车载显示器对比度和清晰度的技术。在目前OLED技术尚无法突破严苛的汽车环境要求的状况下,局部调光是一种首选的成本和性能兼顾的技术。在满足汽车环境要求的同时,大幅提升了显示器的清晰度,提高了显示内容的辨识度,同时成本的上升也在合理范围内。它能给客户带来更好的体验,使驾驶更为安全。本文对它的工作原理以及如何应用进行了阐述,给读者提供了一种思路和方法来提升车载显示器的对比度。Local dimming is a low-cost technology to improve the contrast and clarity of automotive displays.In the current situation that OLED technology cannot break through the requirements of the harsh automotive environment,local dimming is a preferred technology that takes into account both cost and performance.While meeting the requirements of the automotive environment,the clarity of the display is greatly improved,the recognition of the display content is improved,and the cost increase is also within a reasonable range.It gives customers a better experience and makes driving safer.This article explains how it works and how to apply it,providing readers with an idea and method to improve the contrast of automotive displays.
