2019 AUG 14 (NewsRx) -- By a News Reporter-Staff News Editor at Daily Asia Business -- Denso Corporation (Kariya, Japan) has been issued patent number 10,365,128, according to news reporting originating out of Alexandria, Virginia, by NewsRx editors.

The patent’s inventor is Sumiya, Minoru (Kariya, Japan).

This patent was filed on April 15, 2016 and was published online on August 12, 2019.

From the background information supplied by the inventors, news correspondents obtained the following quote: “A conventional display device is known, which is described in Patent Literature 1. The display device (lighting device) of Patent Literature 1 includes a sector-shaped dial having numeric characters and scales formed in the circumferential direction, a substrate arranged at the back side of the dial, light sources (LED) arranged on the substrate in the circumferential direction, and a light introducing object interposed between the dial and the substrate to lead the light from the light source to the dial.

“RGB full color LED is used as the light sources. Blue, green, yellow, orange and red lights are emitted in this order from the small numeric character side towards the large numeric character side in the circumferential direction of the dial. When the light sources are turned on, the luminescence forms a gradation on the dial.”

Supplementing the background information on this patent, NewsRx reporters also obtained the inventor’s summary information for this patent: “Instead of using the light introducing object of Patent Literature 1, the luminosity balance between the light source parts may be controlled by adjusting the transmittance from the light source part, using a light-and-shade part formed on the dial by photograph method. Specifically, the light-and-shade part is relatively dark in an area corresponding to each of the light source parts, and the light-and-shade part is relatively light in an area distant from each of the light source parts, such that the luminosity balance is controlled over the dial.

“In case where each of the light source parts has a first light source and a second light source different in color to make the dial to emit two colors alternately switched on, depending on the arrangement of the first light source and the second light source in each of the light source parts, one light source may be partially interrupted by the other light source. Therefore, while the luminosity balance is controlled overall by the light-and-shade part without being interrupted when the first light source is turned on, unevenness may be generated in the lighting when the second light source is turned on, since the luminosity balance controlled by the light-and-shade part is affected by the interruption.

“It is an object of the present disclosure to provide a display device with a light-and-shade part on a dial, the luminescence color on the dial being changed by two-color light source, by which unevenness is restricted from being generated in luminosity when either light source is turned on.

“According to an aspect of the present disclosure, a display device includes: a dial, a substrate, a plurality of light source parts, and a transmittance adjustment part. The dial has an information item disposed around an outer periphery side with respect to a predetermined central part in a circumferential direction. The substrate is arranged at a side of the dial opposite from a visual confirmation side. The plurality of light source parts is arranged on the substrate in the circumferential direction to correspond to the information item, and the light source part causes the information item to emit light. The transmittance adjustment part is arranged on the dial to face the substrate, and has a low transmittance part in which a transmittance of light is lower than a predetermined value and a high transmittance part in which a transmittance of light is higher than that of the low transmittance part. The transmittance adjustment part adjusts a transmittance of light from the plurality of light source parts. Each of the light source parts includes a first light source and a second light source having different light-emission colors to be alternately switched on lighting.

“The first light source and the second light source are arranged in a same alignment order radially from the predetermined central part. The low transmittance part is located within an area corresponding to the plurality of light source parts, and the high transmittance part is located based on a midpoint position where a distance from the light source parts adjacent to each other is equal in the circumferential direction between the light source parts.

“The information item arranged on the dial emits light, due to the plural luminescence parts disposed on the substrate. Moreover, the transmittance adjustment part is defined on a surface of the dial which faces the substrate. The low transmittance part of the transmittance adjustment part is arranged in the area corresponding to the plural light source parts. Therefore, the light transmittance can be reduced to some extent while the information item in the area corresponding to the light source parts receives much volume of light from the light source part. Moreover, the high transmittance part of the transmittance adjustment part is located at the midpoint position between the adjacent light source parts. Therefore, the light transmittance can be maintained for the information item corresponding to the area between the light source parts, while the volume of light from the light source part is small. Thus, the luminosity balance (evenness) can be obtained over whole the information item.

“The luminescence color is different between the first light source and the second light source of the light source part, and the first light source and the second light source are capable of alternately switched on lighting. The lighting condition of the information item can be switched between the different colors. The first light source and the second light source are arranged radially from the predetermined central part, and the arranged order is the same among the light source parts. Therefore, the first light source is not interrupted by the second light source when the first light source is turned on, and the second light source is not interrupted by the first light source when the second light source is turned on, such that it becomes possible to emit light towards the respective area and the adjacent area of the adjacent light source.

“Because each of the light sources is not affected by the other light sources, approximately the same luminosity is obtained at the low transmittance part between when the first light source is turned on, and when the second light source is turned on.

“Moreover, the high transmittance part is located at the midpoint position where the distance from the light source parts is approximately the same. Similarly, because the light source is not affected by the other light sources, approximately the same luminosity is obtained at the high transmittance part between when the first light source is turned on, and when the second light source is turned on.

“Therefore, approximately the same luminosity balance can be obtained when the first light source is turned on and when the second light source is turned on, due to the low transmittance part and the high transmittance part of the transmittance adjustment part. Accordingly, unevenness in the luminosity can be restricted from being generated by the first light source and the second light source.

“In other words, if the spatial relationship between the first light source and the second light source is arbitrarily set in each of the light source parts, the luminosity balance can be controlled by the transmittance adjustment part for one of the first light source and the second light source. However, the luminosity balance may not be suitably controlled by the transmittance adjustment part for the other side. Such a situation can be avoided.”

The claims supplied by the inventors are:

“What is claimed is:

“1. A display device comprising: a dial having an information item disposed around an outer periphery side with respect to a predetermined central part in a circumferential direction; a substrate arranged at a side of the dial opposite from a visual confirmation side; a plurality of light source parts arranged on the substrate in the circumferential direction to correspond to the information item, the light source part causing the information item to emit light; and a transmittance adjustment part arranged on the dial to face the substrate, the transmittance adjustment part having a low transmittance part in which a transmittance of light is lower than a predetermined value and a high transmittance part in which a transmittance of light is higher than that of the low transmittance part, the transmittance adjustment part adjusting a transmittance of light from the plurality of light source parts, wherein each of the light source parts includes a first light source and a second light source having different light-emission colors to be alternately switched on lighting, the first light source and the second light source are arranged in a same alignment order radially from the predetermined central part, and the low transmittance part is located within an area corresponding to the plurality of light source parts, and the high transmittance part is located based on a midpoint position where a distance from the light source parts adjacent to each other is equal in the circumferential direction between the light source parts, each of the plurality of light source parts is located adjacent to the information item in the radial direction, the first light source and the second light source are located adjacent to each other in the radial direction, the low transmittance part is located adjacent to the plurality of light source parts in the radial direction, and the high transmittance part is located at a midpoint position between the light source parts adjacent to each other in the circumferential direction.
