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.

In the case where one horizontal period becomes shorter as a high frame rate drive of 120 Hz or higher is introduced or the resolution is increased, the time for the writing in of a voltage to the holding capacitor of pixels cannot be sufficiently secured.Two data lines are provided to an electrode for supplying a data voltage to a group of pixels in the vertical direction in such a manner that one data line of the two data lines is connected to one of the two pixels in the vertical direction and the other data line of the two data lines is connected to the other pixel, while one gate line shared by two horizontal lines formed of two pixels, to which different data lines adjacent in the vertical direction are connected, is provided and connected to the electrode for controlling the turning ON/OFF, the data line driving portion has outputs of which the number is two times greater than the number of horizontal pixels in order to make it possible to apply a voltage simultaneously to the pixels for two horizontal lines, and the gate line driving portion has outputs of which the number if ½ the number of vertical pixels by connecting one gate line to two horizontal lines.

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.

An image displaying apparatus, for improving motion blur, in particular, on an image displaying apparatus of hold-type, such as, a liquid crystal display element, etc., comprising: sub-frame producing portions (5, 6) for producing a first sub-frame, a second sub-frame being lower in the gradation than the first sub-frame, from an image of one (1) frame of an image signal inputted; a histogram detection portion (2) for detecting brightness histogram of the image signal; an image determination portion (3) for determining on whether the image signal inputted is a high-gradation image or not, from that brightness histogram; and a level compensation portion (4) for lowering a gradation level of that image signal inputted. And, according to the present invention, lowering the gradation of the high-gradation image keeps the difference in brightness between the first and the second sub-frames, and thereby increasing an effect of improving the motion blur.

In the case where the gray-scale value of the pixel X is the minimum gray-scale value, the data line driving circuit (4) outputs a video signal having a voltage obtained by correcting the positive polarity minimum gray-scale voltage corresponding to the minimum gray-scale value only when outputting a positive polarity video signal. In the above, the data line driving circuit (4) outputs the video signal having the voltage obtained by correcting the positive polarity minimum gray-scale voltage, using a voltage correction amount larger than that which is used in outputting the video signal having the voltage obtained by correcting the positive polarity gray-scale voltage corresponding to the intermediate gray-scale value.

A liquid crystal display device which includes one image signal line which is connected to a plurality of pixels, a scanning line drive part which outputs an ON voltage to the respective pixels in a predetermined order, and a data line drive part which outputs image signal voltages. The data line drive part outputs a gray level signal voltage corresponding to a gray level value of the pixel as an image signal voltage in a first period, and outputs a correction gray level signal voltage different from the gray level signal voltage as an image signal voltage in a second period which precedes the first period. The liquid crystal display device further includes a control part which generates the correction gray level signal voltage based on the gray level value of the pixel and one or plurarity of gray level values of pixels which precede the pixel in order.
