We propose a novel advanced orthogonal modulation format dark return-to-zero frequency shift keying/differential phase shift keying (DRZ-FSK/DPSK) and its realization scheme. The DRZ-FSK/DPSK is generated by the combination of a 40-Gb/s return-to-zero (RZ
提出一种基于U型导光板的特种液晶显示背光模组以缩小侧入式背光模组的厚度。首先,利用Lighttools软件对分别采用1 mm和2 mm U型导光板的曲型侧边背光模组进行了设计和建模;接着对两种不同厚度的曲型侧边背光模组与采用4 mm常规平板式导光板的侧入式背光模组进行仿真并对比分析;最后对采用2 mm U型导光板的曲型侧边背光模组进行了相对偏移的仿真,结果表明其光学性能在强振动和宽温环境中具有较高的稳定性。文章得到一种采用2 mm U型导光板的曲型侧边背光模组,相比较常规侧入式背光模组,在保持了光学性能一
A method based on the XYZLMS interim connection space is proposed to accurately acquire the multi-spectral images by digital still cameras. The XYZLMS values are firstly predicted from RGB values by polynomial model with local training samples and then sp
