The beneficial effect of the display unit of the utility model vehicle electronic device control panel is: by at LGP cone being set, the light that had both effectively blocked via the LGP refraction does not enter cone, can make through the light in the cone again and export without LGP, thereby multiple color illuminator each other optical crosstalk, mixed light have effectively been prevented, design ingenious, simple in structure.
Description of drawings
Fig. 1 is the perspective exploded view of the display unit of vehicle electronic device control panel among the embodiment.
The specific embodiment
Be described in further detail below in conjunction with specific embodiment and the accompanying drawing display unit to the utility model vehicle electronic device control panel.
See also Fig. 1, in one preferred embodiment, a kind of display unit of vehicle electronic device control panel, it comprises panel 10 and locks at the circuit board 60 at panel 10 rears by securing member 80, between circuit board 60 and panel 10, also be provided with a LGP 30 and a reflection diaphragm 20, wherein, circuit board 60 is fixed with the first illuminator 61 and second illuminator 62 of different glow colors on the direction of panel 10, and the button 63 in order to control the second illuminator, can light and close the second illuminator 63 by pressing this button 63, the position of the light direction of corresponding the first illuminator 61 and the second illuminator 62 is formed with respectively first window 11 and Second Window 12 on the panel 10, the light that the first illuminator 61 and the second illuminator 62 send can penetrate from first window 11 and Second Window 12, at this, for ease of understanding, the first illuminator 61 is defined as indicator lamp, the second illuminator 62 is defined as backlight, the quantity of backlight and color can change as required, corresponding, first window 11 is defined as the indicator, and Second Window 12 is defined as the viewing area.
LGP 30 is close to circuit board 60 and panel 10 and is arranged, and it is used for the light that the first illuminator 61 and the second illuminator 62 reflect being derived and being directed to panel 10, so that light can penetrate from first window 11 and Second Window 12; The position of LGP 30 corresponding the first illuminators 61 and the second illuminator 62 also is formed with respectively the first through hole 31 and the second through hole 32.
Between LGP 30 and panel 10, also be provided with a reflection diaphragm 20, this reflection diaphragm 20 covers the first through hole 31 and the second through hole 32 on the LGP 30 fully, and the first window on the panel 11 and Second Window 12, the position of reflection diaphragm 20 corresponding the first illuminators 61 and the second illuminator 62 also is formed with respectively the first transparent area 21 and second transparent area 22 of light-permeable.At this, for ease of understanding, the first transparent area 21 may be defined as the regular figure with the indicator lamp coupling, and the second transparent area 22 may be defined as displaying symbol.
Preferably, the cone 40 that in the first through hole 21, can run through a sheathed both ends open, the first end of this cone 40 is close to the outside that circuit board 10 arranges, also is located at the first illuminator 61 fully, light that the first illuminator 61 reflects is passed and without the transmission of LGP 30, the second end of cone 40 is from passing the first transparent area 21 to reflection diaphragm 20 in the first through hole 21 from the inside of cone 40.Understandable, for better preventing optical crosstalk between the different illuminators, the lighting area of first window 11 is less than the lighting area of the first transparent area 21 of reflection diaphragm 20 on the panel 10.
