When each display unit all moves, divide each zone 61,62 and 63 according to the color of the light that sends from vacuum fluorescent display.For example, when filter can be redness, first area 61 was green, and second area 62 is red, and the 3rd zone 63 is orange.
The layout that the emission light color has been arranged as at first light being launched green first area 61 through red filter, be white by User Recognition then, and simultaneously, its brightness is reduced to about 1/10 suddenly.Its reason is because except redness, and the wave band of other light is by filtering, and the high strength green of 570nm to the 500nm wave band of decaying significantly makes this light have uniform strength in the whole wave band of luminous ray so work as green glow process red filter.
At first light being emitted as red second area 62 through red filter, be its original redness by User Recognition then, and its brightness remains original brightness.This is because the transmit red light of red filter own.
When at first light being emitted as the 3rd orange zone 63 through red filters, the orange of 610nm to 590nm wave band is attenuated to a certain degree, and is light red by User Recognition, and its brightness reduces half.
Therefore, the ruddiness that sends from second area 62 keeps its original brightness, and meanwhile, the user can directly and easily observe corresponding signal by red attraction own.Thus, second area 62 preferably is provided with the display unit or the attention display of supply power supply, and power supply and warning are most important information concerning device for cooking.In addition, first area 61 preferably shows such as requiring satisfies information the cooking time of visual demand by white, and this information is non-important information.In addition, the 3rd zone 63 preferably shows specifying information, and meanwhile, the user can see the operation information of device for cooking easily.
To filter and regional correlation be described with analytic approach below.
At first, use display unit that shows the most important content that must send user's (being second area in the present embodiment) to and filter with same color.In addition, demonstration must send the display unit (being the 3rd zone in the present embodiment) of user's minor coverage to and select vacuum fluorescent display, and this vacuum fluorescent display emission band is near the light of filter color.The display unit (being the first area in the present embodiment) that shows non-important content is selected vacuum fluorescent display, and this vacuum fluorescent display emission band is away from the light of filter color.
Above-mentioned structure has been arranged, and brightness can not decay although the fluorescence of the display unit of transmission most important information passes through filter, and it is transmitted to the user.After this, will be understood that, press the order of importance degree, bigger decay is arranged.Simultaneously, white can be realized under special circumstances, thereby very short and expensive white VFD of life-span can be replaced.
Preferably, the information that sends the user by identification to is most important, makes second area and filter for red.
