The display substrate and the back surface substrate are disposed so as to face one another and such that the electrodes thereof are orthogonal to one another (a simple matrix structure). A top-plane side driving portion is structured by a row electrode driving circuit, a reversing portion, and a reversing switch. When the reversing switch is on, the reversing portion reverses relationships of connection between the row electrode driving circuit and the row electrodes. The backplane side driving portion is structured by a column electrode driving circuit, a reversing portion, and a reversing switch. When the reversing switch is on, the reversing portion reverses relationships of connection between the column electrode driving circuit and the column electrodes. In accordance with the image display device, when a large screen is formed by using a plurality of same image display media, images can be displayed normally at all of the image display media.

摘要： In an image display apparatus and image display method suppress the degradation of display function and the shortening of service life due to long-term use, measurement of a current value is carried out and the measured current value each time a certain time elapses is stored. The integrated value of the current is calculated, and a comparator compares the integrated value with a reference value stored in a storage section for determining whether or not the result is greater than a prescribed value. If the result is affirmed to differ by prescribed value, a recovery voltage is applied, and it is determined whether or not a recovery time has exceeded a stored recovery time. If the excedance of the recovery time is affirmed, the application of the recovery voltage is terminated. If a negation is given at the determination of the greater difference value, the flow is ended. If a negation is given at the determination of the recovery time, the recovery voltage is applied.

摘要： An image processing device is provided for processing image data in order to display an image at an image display medium which is capable of displaying white, black, and colors at individual pixels, which are structured by pluralities of sub-pixels. The judgment component acquires the image data and judges whether there is a chromatic color or a non-chromatic color at each pixel. When a pixel is judged to be non-chromatic, the selection component selects a pre-specified black-and-white sub-pixel set in accordance with a gray level of the non-chromatic color. When a pixel is judged to be chromatic, the conversion component converts color data to a sub-pixel set of black and the color in accordance with a pre-specified condition. Of results of conversion, the replacement component replaces a pre-specified sub-pixel set of colors, in an individual pixel or in a pre-specified sub-pixel group, with a pre-specified black-and-white sub-pixel set.
