US 7658519 B2Abstract
the first to third printed area parts, the white light converting part and the smoked filter are arranged in order thereof to form a layer structure so that broadening of the first and second lights passing through the printed area parts and entering the fluorescent filter can be suppressed. Description
The slider 8 has a side-wall portion 8 a to form a square tube, and an inner slanted wall portion 8 b arranged inside of and integrally formed with the side-wall portion 8 a. The inner slanted wall portion 8 a is shaped like a quadrangular-pyramid tube so that its opening becomes narrower from its front end toward its rear end. The rear end opening of the inner slanted wall portion 8 b is formed so that the light sources 3 and 4 are positioned in the rear end opening, while the tact switch 5 is positioned out of the rear end opening and between the inner slanted wall portion 8 b and the side-wall portion 8 a. The slider 8 is fixed at its front edge side and inside thereof with a color filter 10 having a plurality of printed area parts 10 a to 10 d, which will be described in detail later.
As shown in FIG. 2, the color filter 10 is made of a transparent sheet 10 e with the printed area parts: a first printed area parts 10 a, a second printed area parts 10 b, a third printed area parts 10 c and a background printed area parts 10 d. The first printed area parts 10 a are formed on the front surface of the transparent sheet 10 e to provide a first display indicating a first character “A” excluding overlapped portions of the first character “A” and a second character “E”. The first character “A” is provided as shown in FIG. 4A. The first printed area parts 10 a correspond to overlapped portions of blue printed area parts 101 and fluorescent filter 9 as shown in FIG. 3. The blue printed parts 101 are set to have a transmission efficiency characteristic, with respect to wavelength of light, which is indicated by a line 23 in FIG. 5, so that it can pass the first light, namely blue light in this embodiment.
Incidentally, the printed area parts of the display device shown in FIG. 14 include the blue printed area parts 101, the red printed area parts 102 and the dimmer control printed area parts 103, and are formed on the front surface of the translucent sheet 10 e. On the other hand, when the smoked lens 11 is arranged between the front surface of the translucent sheet 10 e and the rear surface of the fluorescent sheet 9 as shown in FIG. 15, the first display is also provided to have its obscure and broadened peripheral portion under the first light in blue. It is schematically represented by the first area 50 and the second area 60, and the second area 60 becomes larger in area than that shown in FIG. 14, because the first light travels through the translucent sheet 10 e, the smoked lens 11 and the fluorescent filter 9, which becomes a longer distance, being refracted thereby. When the second light source 4 is supplied with electric power, a second display is provided in different color, red for example, but has no obscure portion thereof because the second light does not erect the fluorescent substance of the fluorescent filter 9 when it passes therethrough.
Incidentally, the printed area parts of the display device shown in FIG. 15 are arranged on the rear surface of the translucent sheet 10 e. FIG. 16 shows a display state of the display device of the first embodiment.
The display device of the third embodiment has printed area parts including blue printed area parts 101, red printed area parts 102, dimmer control printed area parts 103 and background printed area parts 10 d, a fluorescent filter 9 arranged on a front surfaces of the printed area parts, a translucent sheet 10 e arranged on a front surface of the fluorescent sheet 9, and a smoked lens 11 arranged on a front surface of the translucent sheet 10 e. In this case, a second area 60, namely an obscure and broadened portion of a first display, can be decreased in area and in obscureness relative to that shown in FIGS. 14 and 15.
