摘要： PROBLEM TO BE SOLVED: To provide a display device of a field sequential system, which can reduce power consumption without deteriorating display image quality.
SOLUTION: In a detection circuit for number of gradations 23, the number of gradations on respective colors (red, green and blue) in pixel data for display is detected. When the detected number of the gradations of all pixel data in the respective colors corresponding to subframes is almost zero, a non-lighting signal is transmitted from a lighting/non-lighting control part 24 to a back light control circuit 35. In the sub-frame (sub-frame where all pixel data in the respective colors become "black") where the number of gradations on all pixel data in the respective colors is almost zero, LED corresponding to the color is not turned on.

摘要： PROBLEM TO BE SOLVED: To realize a display device which leaves no useless output terminals even though a data driver IC on the market is used as it is and has a driving sequence capable of obtaining a good time division-driven display state. SOLUTION: One frame is divided equally into four subframes for every emission color. Each subframe is further divided equally into four intervals and line scanning based on inputted data is conducted in each interval. In the first interval, the polarity mode of a data driver is set into 'L' to display pixel data by using odd number pixels. In the second interval, the polarity mode is set to 'H', the pixel data of the odd number pixels are erased and the pixel data are displayed by using even number pixels. In the third interval, the polarity mode is set to 'L' and the pixel data of the even number pixels are erased by inputting zero gradation data. In the fourth interval, the polarity mode is set to 'H', and zero gradation data are inputted. In the fourth interval which does not participate in display, the back light is turned off.

摘要： PROBLEM TO BE SOLVED: To provide a display device of a field sequential system capable of suppressing a color breakup. SOLUTION: The display device converts original picture data of red, green, and blue each into four color picture data of red, green, blue, and white based on a comparison result of the number of display gradations among individual color picture data, to perform color display while making the input of the converted picture data synchronize with each timing of light emission of backlight in red, green, blue, and white. When such three color picture data are converted into four color picture data based on the number of display gradations, the color breakup is suppressed by setting the predetermined number of display gradations according to the comparison result of red, green, and blue, distributing the predetermined number of display gradations to sub-frames where a mixed color (white) is displayed, and displaying the difference in the sub-frames of the monochromatic light (red, green, blue).

摘要： PROBLEM TO BE SOLVED: To obtain a display device which can maintain reliability of the operation in a high temp. environment, which has a wide temp. range of stable operation and which is suitable for the mass production by using cyanocellulose as an alignment layer material and specifying the thickness of the alignment layer. SOLUTION: Aligment layers 13, 23 comprises cyanocellulose films and the film thickness of each film is controlled to 50 to 100 nm. By using cyanocellulose as a film material, uniform alignment films 13, 23 can be obtd. by transfer printing method which is far more excellent in the productivity compared to spin coating method. By controlling the film thickness to >=50 nm, the hysteresis width Δ at 60 deg.C is >=1 V, which means the reliability of the operation using the memory effect can be maintained. An electrode substrate 10 having the alignment layer 13 above described, and an electrode substrate 20 having the alignment layer 23 formed in the same way are disposed to face each other. In this process, the space between the facing substrates is controlled by a silica spacer 31.
