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： There is disclosed a display device which is driven by a two-field drive scheme. That is, brightness corresponding to one frame of image is obtained in two scans. The display screen is divided into plural regions. One of the regions is driven by a black insertion method. The other region is driven by a pseudo-normal drive method. In this method, an image based on the same display data is displayed twice. The display data is converted such that the gamma characteristics of the pseudo-normally driven region are substantially equal to the gamma characteristics of the region driven by the black insertion method. If necessary, each individual pixel in the boundary region between the region driven by the black insertion method and the region driven by the pseudo-normal drive method is displayed black or white. The boundary region has a width of at least two pixels.

摘要： A display device includes an LUT storing circuit and an LUT holding circuit, a representative point selecting circuit, and a compensation amount calculating circuit. The storing and holding circuits store and hold not compensation amounts of all points but compensation amounts of representative points in a lookup table. The representative point selecting circuit refers to a compensation amount for a representative point in the lookup table and three representative points neighboring an interpolating object point for deriving a compensation amount of each interpolating object point except the representative points in the lookup table. The compensation amount calculating circuit calculates the compensation amount of each interpolating point except the representative points by performing an interpolating operation with respect to the compensation amounts of the three neighboring representative points.
