    • The driving of an active matrix organic light emitting display (AMOLED) shall be improved. A pulsing grayscale rendition shall be combined with an improved motion rendition when driving the AMOLED with analog signals. Therefore, there is provided a data signal which is applied to each cell of the AMOLED for displaying a first grayscale level of a pixel of the image during a first group of sub-frames (SFO to SF5)for displaying at least a second grayscale level of a pixel of the image during at least a second group of sub-frames (SF' 0 to SF' 5). The first group of sub-frames (SFO to SF5) and the at least second group of sub-frames (SF' 0 to SF' 5) are constituting a video frame N. Each group of sub-frames is divided into a plurality of sub-frames. Each, the first group of sub-frames and the second group of sub-frames is belonging to a separate complete image of the display (AMOLED). The data signal of a cell comprises plural independent elementary data signals wherein each of the elementary data signals is applied to the cell during a sub-frame and the grayscale level displayed by the cell during the respective group of sub-frames depends on the amplitude of the elementary data signals and the duration of the sub-frames. With this concept, a flicker- free and a very high level of motion rendition can be offered.
    • 有源矩阵有机发光显示器(AMOLED)的驱动将得到改善。 当用模拟信号驱动AMOLED时,脉冲灰度渲染应与改进的运动再现相结合。 因此,提供了一种数据信号,其被应用于AMOLED的每个单元,用于在第一组子帧(SFO至SF5)期间显示图像的像素的第一灰度级,以显示至少第二灰阶级 在至少第二组子帧(SF'0至SF'5)期间的图像的像素。 第一组子帧(SFO至SF5)和至少第二组子帧(SF'0至SF'5)构成视频帧N.每组子帧被分成多个 子帧。 每个,第一组子帧和第二组子帧属于显示器(AMOLED)的单独的完整图像。 单元的数据信号包括多个独立基本数据信号,其中每个基本数据信号在子帧期间被施加到单元,并且在相应的子帧组期间由单元显示的灰度级依赖于 基本数据信号和子帧的持续时间。 有了这个概念,可以提供无闪烁和非常高水平的运动渲染。

    • A high-resolution interlaced scanning method of a flat display and a flat display apparatus thereof are provided to improve image quality by applying an interlaced scanning scheme in the flat display apparatus. A high-resolution interlaced scanning flat display apparatus includes a decoder(200), a scaling unit(230), and a display unit. The decoder receives image signals. The scaling unit receives image signals inputted to the decoder or external image signals, forms a first screen by scanning cells arranged in the odd fields of the image signals, and forms a second screen by scanning cells of other fields adjacent to cells of even lines in the odd fields. The display unit displays the first and second screens formed in the scaling unit.
