【摘要】：主動陣列有機(jī)發(fā)光二極管(AMOLED)面板具有低功耗、視角廣、柔韌性等優(yōu)點(diǎn),被視為下一代顯示技術(shù)的關(guān)鍵。但是它通常采用RGBG型像素排列,而圖像的像素結(jié)構(gòu)是RGB,為了實(shí)現(xiàn)圖像的顯示,迫切需要研究RGB-RGBG的轉(zhuǎn)換算法。本文提出了一種基于權(quán)重因子(BWF)的RGB-RGBG像素結(jié)構(gòu)轉(zhuǎn)換算法,并在現(xiàn)場可編程邏輯門陣列(FPGA)上實(shí)現(xiàn)電路。通過對原灰階進(jìn)行權(quán)重求和,得到各個RGBG子像素的灰階。這種方法可以將灰階誤差降至最低。此外,彩邊效應(yīng)得到極大的改善。實(shí)驗結(jié)果表明,相比于DA算法,BWF算法處理所得圖像的PSNRU和PSNRV分別提高了9.2%和9.3%,MSE比DA算法降低19.5%。該算法研究通過FPGA驗證,結(jié)果表明,BWF處理后的圖像顯示效果優(yōu)越。
[Abstract]:The active array organic light-emitting diode (AMOLED) panel has the advantages of low power consumption, wide viewing angle, flexibility and so on, so it is regarded as the key of the next generation display technology. However, it usually uses RGBG type pixel arrangement, and the pixel structure of image is RGB,. In order to realize image display, it is urgent to study the conversion algorithm of RGB-RGBG. In this paper, a RGB-RGBG pixel structure conversion algorithm based on weighted factor (BWF) is proposed, and the circuit is implemented on the field programmable gate array (FPGA). By summing the weights of the original gray scale, the gray scales of each RGBG sub-pixel are obtained. The grey scale error can be minimized by this method. In addition, the color edge effect is greatly improved. The experimental results show that compared with the DA algorithm, the PSNRU and PSNRV of the image processed by the BWF algorithm are increased by 9.2% and 9.3%, respectively, which are 19.550% lower than that of the DA algorithm. The algorithm is verified by FPGA, and the result shows that the image display effect after BWF processing is superior.
