    • A system and method are disclosed for performing dot inversion with standard drivers and backplane on novel display panel layouts. Suitable dot inversion schemes are implemented on a liquid crystal display having a panel and a driver circuit. The panel substantially comprises a subpixel repeating group, the group having a even number of subpixels across a first direction. The driver circuit comprises a set of drivers, coupled to the panel providing image data signals to the panel, the signals effecting substantially a dot inversion scheme to the panel. The drivers are also substantially connected to the columns of the panel in a sequence along the driver circuit wherein at least one driver is not connected to a column of the panel, and at least two subpixel regions of the panel having same colored subpixels in the two regions with substantially different polarities.

    • An image processing method comprises: (A) separating R and B data and G data from input data; (B) loading data corresponding to respective odd rows of gamma-converted R and B data, and storing data corresponding to respective even rows of the R and B data adjacent to the loaded odd rows; (C) loading two R data of the even row, along with two R data of the odd row corresponding to a first display position, so as to form a 2×2 R pixel area, and loading two B data of the even row, along with two B data of the odd row corresponding to a second display position, so as to form a 2×2 B pixel area; (D) computing the sharpness of the corresponding display data by comparing the data in each of the R and B pixel areas column by column and row by row; (E) computing the luminance of the display data by taking the average value of the data corresponding to the odd row of each of the R and B pixel areas; (F) determining the gray scale value of output R data by adding the sharpness to the luminance of the R data, and determining the gray scale value of output B data by adding the sharpness to the luminance of the B data; and (G) combining the inverse-gamma-converted R and B data and the input G data and then outputting the combined data according to the sub-pixel structure of the display panel.
    • 一种图像处理方法包括:(A)从输入数据中分离出R和B数据和G数据; (B)加载对应于伽马变换的R和B数据的各个奇数行的数据,以及存储与加载的奇数行相邻的R和B数据的相应偶数行的数据; (C)加载偶数行的两个R数据以及对应于第一显示位置的奇数行的两个R数据,以形成2×2R像素区域,并加载偶数行的两个B数据, 以及对应于第二显示位置的奇数行的两个B数据,以形成2×2B像素区域; (D)通过逐列和逐行比较每个R和B像素区域中的数据来计算相应显示数据的清晰度; (E)通过获取对应于每个R和B像素区域的奇数行的数据的平均值来计算显示数据的亮度; (F)通过将锐度与R数据的亮度相加来确定输出R数据的灰度值,并且通过将清晰度与B数据的亮度相加来确定输出B数据的灰度值; 和(G)组合逆伽马变换的R和B数据和输入G数据,然后根据显示面板的子像素结构输出组合数据。
