應用於液晶顯示器之可適性區域背光控制顯示器積體電路設計
為了解決CABC PWM 的問題,作者蔡欣儒 這樣論述:
本論文提出三種區塊可適性調光設計,用以實現液晶顯示器背光控制器積體電路實現。此演算法基於亮度分析與預測節省能源幅度,並用亮度增強法來補償失真影像,此論文提出三種自適性調節演算法為基於平均亮度、最大亮度和高斯分佈來進行亮度分析。為了提高影像品質,此演算法開法由影像整張運算改由區塊運算取代整幀運算區塊運算。在硬體方面,本論文所提出的這種設計是由0.18微米技術合成,為了減少硬體成本及運算複雜度,利用查表轉換運算來進行運算去減少高位元的乘除法器並且減少運算時間。新的平均值,新的最大值和高斯分佈的方法晶片面積在100 MHz的工作時分別為528,099平方微米、609,960平方微米和630,113
平方微米與以前的設計相比,本論文提高了平均35.51分貝、42.78分貝和45.42分貝與降低46.24%、50.78%和48.32%液晶顯示器背光能源消耗晶片面積在100 MHz的工作時為528,099平方微米。
