Display device
View Patent ↗[Problem] To provide a display device able to visibly and clearly display a relationship between a moving condition of an indicating member and an indexes. [Means for solving problem] A display device 1 includes: a design pattern 31 on which a plurality of numerical markers 35 are arranged; a pointer 32 configured to move along the numerical markers 35 , and display a position corresponding to a measured amount of a moving object; a display member 15 configured to display an afterimage 33 extending in a direction M′ opposite to a moving direction M of the pointer 32 ; and a CPU 10 configured to control the display member 15 to display the afterimage 33 . A tip 32 a of the pointer 32 is overlapped with an area 36 on which the numerical markers 35 are arranged. The CPU 10 makes the afterimage 33 extend from the tip part 32 a of the pointer 32 to be overlapped with the area 36 on which the numerical markers 35 are arranged, and makes the numerical markers 35 visible through the afterimage 33.
1. A display device for a graphic meter comprising:
a design pattern on which a plurality of indexes include outer-edge marks and numerical marks arranged within an arc shape:
an indicating member configured to move along the indexes, and indicate a position corresponding to a measured amount of a moving object to display the measured amount by a collaboration of the indexes and the indicating member;
a display member configured to display
the numerical marks visually contained within an upper and lower edge,
a band-shaped afterimage of the indicating member extending in a direction opposite to a moving direction of the indicating member, wherein the afterimage is visually contained within an upper and lower edge, and
the afterimage being displayed within the design pattern such that the afterimage visually extends outside of the upper edge of the numerical marks and the numerical marks visually extend outside of the lower edge of the afterimage; and
a display control member configured to control the display member to display the afterimage,
wherein a part of the indicating member is overlapped with an area on which the indexes are arranged,
wherein the display control member makes the afterimage extend from only a part at a tip end of the indicating member to be overlapped with the area on which the indexes are arranged, and makes the indexes visible through the afterimage, and
wherein the indicating member and the afterimage overlap with the indexes, and wherein the display member displays the design pattern, and includes an index identifying member that identifies a closest emphasized index which is the closest to the indicating member among the indexes juxtaposed in an arc of the design pattern, and
wherein the display control member displays the closest index emphasized within the arc compared with other indexes on the arc of the design pattern.
2. The display device as claimed in claim 1 , wherein the display control member makes the afterimage gradually displayed darker as the afterimage is away from the indicating member.
3. The display device as claimed in claim 1 ,
further comprising a moving amount calculating member configured to calculate a moving amount of the indicating member per a specific time period,
wherein the display control member makes the afterimage displayed in a size proportional to the moving amount of the indicating member calculated by the moving amount calculating member.
4. The display device as claimed in claim 2 ,
further comprising a moving amount calculating member configured to calculate a moving amount of the indicating member per a specific time period,
wherein the display control member makes the afterimage displayed in a size proportional to the moving amount of the indicating member calculated by the moving amount calculating member.
5. The display device as claimed in claim 2 ,
wherein the display member displays the design pattern, and includes an index identifying member configured to identify the closest index to the indicating member among the indexes, and
wherein the display control member makes the index identified by the index identifying member more emphatically displayed than other indexes.
6. The display device as claimed in claim 3 ,
wherein the display member displays the design pattern, and includes an index identifying member configured to identify the closest index to the indicating member among the indexes, and
wherein the display control member makes the index identified by the index identifying member more emphatically displayed than other indexes.
7. The display device as claimed in claim 4 ,
wherein the display member displays the design pattern, and includes an index identifying member configured to identify the closest index to the indicating member among the indexes, and
wherein the display control member makes the index identified by the index identifying member more emphatically displayed than other indexes.
