用以产生多重明暗层次图像的显示控制器制造技术

一种显示控制器，用以经由多个连续帧而产生一幅具有多重明暗层次的图像于一由多个二元状态像素以阵列方式所组成的显示装置上，该多个像素被区分成多个具有相同尺寸的子像素组，该显示控制器包含：　　　　一像素计数器，用以指定一期望的像素的行数目；　　　　一扫描线计数器，用以指定该期望的像素的列数目；　　　　一图像存储器，响应于该期望的像素的该行数目与该列数目而提供一明暗层次数据，该明暗层次数据用以指示将产生于该期望的像素上的明暗层次色阶；　　　　一波形图案存储器，用以提供多组波形图案信号至该显示装置，该多组波形图案信号中的每一组具有相同数目的波形图案信号，其中每一波形图案信号具有一预定数目的位且当应用于一像素时产生一不同的明暗层次色阶，其中每一位是用在该多个连续帧中的一对应的帧中显示；以及　　　　一波形图案选择器，响应于该期望的像素的该行数目与该列数目而输出一波形图案选择信号，使该波形图案存储器对于相邻的两个子像素组分别提供该多组波形图案信号中的不相同的两组，其中：　　　　该波形图案存储器响应于波形图案选择信号而确定提供该多组波形图案信号中的一选定组，响应于该明暗层次数据而确定提供该选定组波形图案信号中的一选定波形图案信号，并且按照该多个连续帧的进行而依序提供该选定波形图案信号的对应的位；　　　　分别提供至该相邻的两个子像素组的该多组波形图案信号中的该不相同的两组被设定成使该相邻的两个子像素组在该多个连续帧的至少一帧中处于彼此不同的状态；并且　　　　该多个连续帧的帧速率被设定成足够高以避免视觉干扰。（*该技术在2013年保护过期，可自由使用*）

Display controller for generating multiple light and dark level images

A display controller, via multiple consecutive frames and a picture of a multi gradation image on a pixel by more than two yuan of state in array composed of a display device, the plurality of pixels are divided into a plurality of sub pixel groups with the same size, the display controller includes: pixel counter, with a pixel to specify the desired number of lines; a scan line counter, with the number of pixels to specify the desired image pixel; a memory, in response to the expectations of the line number and the column number and provide a gradation data, gradation gradation data to the color instructions will be produced in the pixel on the desired waveform pattern; a memory, providing multiple sets of waveform pattern signal to the display device to the Each group has the same number of signal waveform pattern group waveform pattern signal, wherein each waveform pattern signal having a predetermined number of bits and when applied to a pixel when a different color shades, each of which is a display in the successive frames of a frame should be in; and a waveform pattern selector, pixels in response to the expectations of the line number and the column number and output waveform pattern selection signal, the waveform pattern memory for two groups of adjacent sub pixels respectively provide the multiple waveform pattern signal in the same two groups, including: the waveform pattern memory in response to the selection signal waveform pattern and determine the number of groups to provide a signal waveform pattern in the selected group, in response to the brightness level data and determine the selected group of waveform In a selected pattern signal waveform pattern signal, and in accordance with the plurality of consecutive frames and sequentially corresponding to the selected signal waveform pattern of two sub pixels respectively; group of the plurality of waveform pattern signal to the adjacent in the same two groups is set to the two sub the adjacent pixel group is different from each other in at least one frame of the plurality of consecutive frames; and the plurality of successive frames of the frame rate is set high enough to avoid visual interference.
