LED全彩租赁屏图像质量探讨
The Discussion of Full Color Rental LED Screen Image Quality
摘要
租赁屏一般由分时段采购的批量箱体组成,不同批次箱体的亮度差异、色域空间差异等导致了整体屏幕图像质量下降。本文首先用亮色度校正探讨解决不同批次间亮色度差异的方法,然后从不同角度观看、低灰图像显示以及LED光衰等几个角度分析了该方法存在的局限性,最后指出LED显示屏厂家需要在LED选灯、配光曲线、LED亮色度等多个方面控制生产工艺,配合逐点亮色度校正技术改善租赁屏的显示质量。
Abstract
LED Screen Rental is generally composed by the sub-period purchasing boxes, the differences in brightness and color space lead to a decline of the full screen image quality. This paper first use the brightness and chrominance correction to solve this problem, then from different angles of view, low gray image display and LED brightness decay, analyze the limitations of this method, and finally point out that the LED display manufacturers should control the production process in choosing the LED lights, light distribution curve, LED brightness and other aspects, together with brightness and chrominance correction to improve rental LED screen display quality.
