Patent number: 9064471Abstract: A display device for a vehicle includes a liquid crystal panel, a light source, and a controller. The liquid crystal panel includes a particular display pixel and a normal display pixel. The controller controls the ratio of the gradation value of the normal display pixel to a set gradation value of the normal display pixel as a gradation ratio of the normal display pixel. At the same time, it controls the ratio of the gradation value of the particular display pixel to a set gradation value of the particular display pixel as a gradation ratio of the particular display pixel. Further, the controller sets first and second modes as a control mode, the first mode in which the light source emits light, and the second mode in which the light source emits light with brightness lower than in the first mode. In the first mode, the controller sets the gradation ratio of the normal display pixel and the gradation ratio of the particular display pixel at a particular time to a maximum ratio.Type: GrantFiled: December 13, 2013Date of Patent: June 23, 2015Assignee: DENSO CORPORATIONInventors: Yukihide Shibata, Miki Kato, Makoto Inomata, Tomoyuki Miyagaki

Patent number: 8743153Abstract: A display device for a vehicle includes a liquid crystal panel (10), a light source (40), and a controlling means (50). The liquid crystal panel includes a particular display pixel (72) and a normal display pixel (62). The controlling means controls the ratio of the gradation value of the normal display pixel to a set gradation value of the normal display pixel as a gradation ratio of the normal display pixel. At the same time, it controls the ratio of the gradation value of the particular display pixel to a set gradation value of the particular display pixel as a gradation ratio of the particular display pixel. Further, the controlling means sets first and second modes as a control mode, the first mode in which the light source emits light, and the second mode in which the light source emits light with brightness lower than in the first mode.Type: GrantFiled: November 21, 2007Date of Patent: June 3, 2014Assignee: Denso CorporationInventors: Yukihide Shibata, Miki Kato, Makoto Inomata, Tomoyuki Miyagaki

Patent number: 8558683Abstract: A display apparatus for a vehicle includes: a display element; an image generation element for generating a vehicle image, an analog image and an indication image; and a display controller. The analog image includes an indication position and multiple indexes arranged on an upside and downside of the indication position. The indication image shows the current vehicle speed at the indication position. Each index shows a corresponding vehicle speed. Display dimensions of each index are inverse proportion to the corresponding vehicle speed, and a distance between the indication position and each index is proportion to a difference between the current vehicle speed and the corresponding vehicle speed. The display controller controls the display element to display the indication image at the indication position of the analog image.Type: GrantFiled: March 24, 2010Date of Patent: October 15, 2013Assignee: Denso CorporationInventors: Ryoichi Nishikawa, Yasuhisa Yamashita, Hiroki Matsui, Takaaki Muramatsu, Kenichirou Karikomi, Tomoyuki Miyagaki, Hitoshi Sugiyama

Patent number: 8274459Abstract: A display apparatus for use in a vehicle has a liquid crystal display panel, and the panel includes a first pixel area for displaying a meter image that represents vehicle condition values, and a second pixel area for displaying an outside image that calls attention of occupants as a warning image. Further, an input unit of the apparatus receives inputs of adjustment value from occupants of the vehicle for adjusting brightness of the meter image and the outside image. A main control unit and a drawing unit of the apparatus cooperatively serve as a controller of the apparatus by changing gradation ratio of the first and second pixel areas so that the gradation ratio of the second pixel area becomes greater than the gradation ratio of the first pixel area according to the input of the adjustment value.Type: GrantFiled: April 10, 2008Date of Patent: September 25, 2012Assignee: Denso CorporationInventors: Miki Kato, Yukihide Shibata, Tomoyuki Miyagaki
