摘要： High-order bits to be utilized for current-frame display data and previous-frame display data, and low-order bits to be utilized for the current-frame display data alone are stored in independently controllable memory areas. For reading the current-frame display data from a frame memory, data of the high-order bits and data of the low-order bits are read. For reading the previous-frame data, the high-order bits alone are read. Thus, since a period during which the data of the low-order bits that is not utilized for the previous-frame display data is stored in the memory is shortened, a required memory capacity can be reduced. The data transfer time can be reduced by the time required for memory read for the data of the low-order bits that is not utilized for the previous-frame display data.
摘要翻译： 用于当前帧显示数据和前一帧显示数据的高位数，以及仅用于当前帧显示数据的低位比特存储在独立可控存储区域中。 为了从帧存储器读取当前帧显示数据，读取高位数据和低位数据的数据。 为了读取前一帧数据，只读取高位。 因此，由于缩短了对前一帧显示数据未被利用的低位数据的数据存储在存储器中的时段，所以可以减少所需的存储器容量。 数据传输时间可以减少对于未用于前一帧显示数据的低位的数据的存储器读取所需的时间。

摘要： A display device and system are disclosed, wherein the display system is so configured that an n-fold rate increasing circuit is arranged with a signal generating device instead of with the display device to realize a low-cost n-fold rate impulse-type drive. The n-fold rate display data is output to the display device from the signal generating device, and the display device includes a circuit to subject the input n-fold rate display data to the data conversion process for the n-fold rate impulse drive. In addition to the n-fold rate display data, an identification signal for identifying the position of the turn of the frames of the original video signal is input to the display device to prevent the erroneous data conversion operation.

摘要： A hold-type display device reduces the blur of a moving image and makes less conspicuous the color shift caused due to different blur positions among RGB. In the case where the relative brightness of the video data of one or two of the three primary colors RGB changes from between 0 and 0.5 inclusive for the previous frame to between 0 and 0.5 inclusive for the present frame, the video image of the one or two colors is delayed by one frame and displayed.
