    Abstract: The present invention aims to provide a display device capable of displaying an image in a color maintaining a hue and a tone expected from an input signal. In a field-sequential liquid crystal display device, when a red image is displayed, red light is transmitted in the first subframe period, and further, green light and blue light are transmitted in the second and third subframe periods, respectively. Therefore, the blue component of an input signal is adjusted such that the transmittance of the liquid crystal panel is at a predetermined value even in the third subframe period. As a result, the hue of an image displayed on the liquid crystal panel is the same as or almost the same as the hue of red expected from the input signal. Moreover, the color of red displayed on the liquid crystal panel maintains the tone value of the color expected from the input signal.

  • Patent number: 8334858
    Abstract: For the purpose of providing a display apparatus capable of improving display quality by expanding the light-emission area of pixels by improving the layout of pixels and common power-feed lines formed on a substrate, pixels (7A, 7B) including a light-emission element (40), such as an electroluminescence element or an LED element, are arranged on both sides of common power-feed lines (com) so that the number of common power-feed lines (com) is reduced. Further, the polarity of a driving current flowing between the pixels (7A, 7B) and the light-emission element (40) is inverted so that the amount of current flowing through the common power-supply lines “com” is reduced.

  • Patent number: 8330755
    Abstract: An image display with high brightness where a long time can be secured for light emission of self-luminous elements can be implemented using only line memories. The period for the writing in of a display voltage (period for writing in of data) continues for a number of lines (three lines), and the reset pulse becomes of a “high” state. Subsequently, operation for three lines is carried out collectively during a triangular wave period (period for writing in of a triangular wave voltage), and only the light emission controlling pulse becomes of a “high” state. During the period for the writing in of a triangular wave voltage, the writing in of a triangular wave voltage from the second time onward is rewriting of a triangular wave voltage, and thus, the period for rewriting the display voltage (dotted line portion) becomes unnecessary, and a longer period for light emission, where the light emission controlling pulse becomes of a “high” state, can be secured.
