Patent number: 7903062Abstract: The cold cathode tube for illuminating pixels with light which is in accordance with an output signal has luminance which gradually increases at a rise and gradually decreases at a fall per one frame time. The cold cathode tube contains a fluorescent material of only one of three primary colors of light, and has a certain OFF period or dimming period per one frame time. Between a diffusing plate and a reflecting plate are provided partition walls for parting emitting areas, so that the illumination light of one cold cathode tube does not reach the display elements to be illuminated by the other cold cathode tubes. The emission of each display element is changed per one frame time between a normal ON state and a dim state. The cold cathode tube has two or more OFF periods within one frame time, and, luminance of the cold cathode tube is changed per one frame period.Type: GrantFiled: April 28, 2005Date of Patent: March 8, 2011Assignee: Sharp Kabushiki KaishaInventors: Koichi Miyachi, Akihito Jinda, Makoto Shiomi

Patent number: 7522140Abstract: While image data is written into either one of first, second, third frame memories 1, 2 and 3, image data are repetitively read two times from the remaining two memories in one vertical synchronization interval and transferred to an arithmetic unit 4, and this operation is executed with the frame memories changed sequentially. An arithmetic unit 4 refers to a look-up table on the basis of two inputted data values and, when the data value of the current image signal is greater than the data value of the previous image signal, the unit 4 transfers image data of a value greater than the data value of the current image signal to a liquid crystal display device 5. Thus, the step response characteristic is improved for the improvement of the dynamic image display quality.Type: GrantFiled: September 29, 2005Date of Patent: April 21, 2009Assignee: Sharp Kabushiki KaishaInventors: Akihito Jinda, Koichi Miyachi, Hidekazu Miyata

Patent number: 7312777Abstract: A liquid crystal display device carries out tone display with pixels by applying a tone voltage according to tone data to each pixel in each frame, and includes: an LUT memory, which receives tone data of a display frame and tone data of an immediately preceding frame, for converting and outputting the tone data of the display frame; a source driver for applying the tone voltage to the pixels based on the converted tone data outputted from the LUT memory; and a liquid crystal cell, which makes up the pixels, for realizing tone display by the applied tone voltage, wherein the LUT memory stores beforehand output tone data which is specified by the tone data of the display frame and the tone data of the immediately preceding frame. This reduces a voltage change of pixel electrodes which is associated with a tone change to suppress unmatched tone display, thereby improving image quality of moving images.Type: GrantFiled: September 21, 2004Date of Patent: December 25, 2007Assignee: Sharp Kabushiki KaishaInventors: Hidekazu Miyata, Makoto Shiomi, Akihito Jinda, Kazunari Tomizawa, Koichi Miyachi

Patent number: 7071955Abstract: A color display device includes a shutter type color display and signal processing means. The signal processing means has color conversion processing means for increasing a gradation level of a color signal having the highest gradation level while decreasing a gradation level of a color signal having the lowest gradation level when the gradation levels of the plural color signals are not equal one another, and for outputting a color signal has been processed to the shutter type color display. Further, a color display having a reflective member or a diffuse transmission member provided on a display screen or in the vicinity of the display screen, a color plasma display, or a color field emission display can also be used instead of the shutter type color display. Thus, even when chroma of the color display is low, a display in high chroma can be ensured.Type: GrantFiled: May 28, 2002Date of Patent: July 4, 2006Assignee: Sharp Kabushiki KaishaInventors: Koichi Miyachi, Akihito Jinda, Hidekazu Miyata, Kazunari Tomizawa, Makoto Shiomi
