  • Publication number: 20090153498
    Abstract: A communication method controlling system includes a control apparatus and a writing apparatus. The writing apparatus includes a function that employs plural communication methods. When a user selects content by manipulating an operation terminal, a control apparatus detects the content ID, and transmits corresponding content data and communication method information to the writing apparatus. Based on the received content data, the writing apparatus writes the contents data and displays a content image on electronic paper, and changes a communication method according to the received communication method information and uses an LED lamp, for example, to notify the user which communication method has been selected. When the user performs an operation according to the available communication method, information is transmitted from the writing apparatus to a port using the communication method.

  • Patent number: 7230604
    Abstract: A drive method for a display medium containing two particle types can drive the display medium with a low voltage and thereby achieve high image resolution, downsize the drive circuit, and lower the cost while improving the durability of the display medium. The display medium has a pair of substrates, at least one of which is transparent, disposed with a gap therebetween, and two types of particles of different color and charge characteristics sealed between the pair of substrates. To change the displayed image, the drive method applies a voltage pulse to at least one of the pair of substrates to pull particles that are to move to the substrate to which the particles that are to move adhere, and then applies a voltage pulse to move the particles that are to move to the substrate opposite the substrate to which the particles that are to move adhere.

  • Publication number: 20070047003
    Abstract: 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 exceedance 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.

  • Publication number: 20070046621
    Abstract: An image display device and image display method are provided. The device and method can prevent changes in image density and contrast, which are caused by repeated displaying over long periods of time and changes in environment, by employing accurate electric current detection, due to the following operations. Voltage measurement is initiated with a detection circuit. Next, the application of drive voltage is initiated with a drive power source. An electric current value is calculated from the measured voltage value and the electric current value is temporarily stored. The electric current values are stored every set amount of time and the storage thereof accumulates. Application of the drive voltage is terminated and the integral value of the electric current is calculated in accordance with formulas.

  • Publication number: 20070031031
    Abstract: 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.

  • Patent number: 7119787
    Abstract: In an image display device of the present invention, a display substrate has m row electrodes, and a back surface substrate has n column electrodes. 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.
