也就是说,出现液晶面板53的虚像53i和孔54a的外周的虚像54ai,因此驾驶员可以看见这些虚像53i、54ai。 That is, the liquid crystal panel 53 appears as an imaginary outer circumference of the dummy hole 53i and 54a as 54ai, so that the driver can see the virtual image 53i, 54ai. 虚像54ai的直径Di大于孔54a的实际外周的直径D。 The actual virtual image diameter of the outer periphery of the hole 54a is larger than Di 54ai diameter D.

因此,驾驶员看见由孔54a的外周环绕的液晶面板53为由虚像54ai环绕的放大虚像53i。 Thus, the liquid crystal panel seen by the driver surrounded by an outer periphery 54a of the hole 53 by a virtual image enlarged virtual 54ai surrounding image 53i.

就是说,液晶面板53的图像被放大以由此增强液晶面板53的可视性。 That is, the image of the liquid crystal panel 53 is enlarged to thereby enhance visibility of the liquid crystal panel 53.

此处,组合透镜55、56的放大比E(=Di/D)被设定为约1.4。 Here, a combination of lenses 55 and 56 is set amplification ratio E (= Di / D) of about 1.4. 但是,通过改变间距S和菲涅耳透镜55和凸透镜56的焦点F中的至少一个,比E可以作为设计参数被改变,而不限于1.4。 However, the focus F 56 of at least one, E ratio can be varied as a design parameter S by changing the pitch and a Fresnel lens and a convex lens 55 without being limited to 1.4.

接下来,将参照图11解释组合仪表1的电路。 Next, an explanation combination meter circuit 11 with reference to FIG.

接下来,将在以下解释组合仪表1的操作。 Next, the operation instrument 1 will be explained in the following composition.

(1)当点火开关接通时当点火开关31接通时,控制器9检测到它以由此点亮发光二极管3、4和背光57。 (1) When the ignition switch is turned on when the ignition switch 31 is turned on, the controller 9 detects it to thereby lighting the light emitting diode and a backlight 3, 4, 57. 速度表A的刻度盘2和指针8由此被光亮地显示,并且液晶面板53等被明亮地照明。 Dial 2 and the pointer of the speedometer A bright display is thus 8, and the liquid crystal panel 53 and the like are brightly illuminated.

此外,控制器9基于来自速度传感器35的检测信号而驱动移动件6,以将指针轴7旋转一个与车辆行进速度相对应的角度。 Further, the controller 9 drives the movable member 6 based on the detection signal from the speed sensor 35, the pointer to the rotary shaft 7 and a vehicle traveling speed corresponding to the angle. 此外,控制器9基于来自速度传感器35的检测信号驱动液晶面板53以在测距仪B上显示行进距离并更新显示数据。 Further, the controller 9 drives the liquid crystal panel based on the detection signal from the speed sensor 35 of the display 53 to display the travel distance data and updated on the rangefinder B. 另外,控制器9基于来自车门传感器36至39的检测信号驱动液晶面板53而在车门指示器C上显示每个车门的关闭状态。 Further, the controller 9 drives the liquid crystal panel 53 based on the detection signal from the door sensor 36 to 39 of the display-off state of each door on the door indicator C.

(2)当点火开关断开时当点火开关31断开时,控制器9检测到它以由此熄灭发光二极管3、4和背光57。 (2) When the ignition switch is turned off when the ignition switch 31 is turned off, the controller 9 detects it to thereby extinguish the light emitting diodes 3, 4 and a backlight 57. 此外,控制器9停止驱动移动件6和液晶面板53。 Further, the controller 9 stops driving the movable member 6 and the liquid crystal panel 53.

如上所述,在根据第五实施例的组合仪表1中,具有孔54a的装饰板54布置在液晶面板53前面以由此使得观察者能够经由孔54a看到液晶面板53。 As described above, according to the fifth embodiment of the combination meter 1, having a hole 54a of the trim panel 54 is disposed in front of the liquid crystal panel 53 to thereby enable the viewer to see the liquid crystal panel 53 through the holes 54a. 此外,菲涅耳透镜55和凸透镜56布置在装饰板53前面;即,菲涅耳透镜55和凸透镜56布置在液晶面板53相对装饰板54的相反侧上。 In addition, the Fresnel lens 55 and a convex lens 56 disposed in front of the trim panel 53; i.e., 56 disposed on the opposite side of the Fresnel lens and the convex lens 55 in the liquid crystal panel 53 relative to the trim panel 54. 菲涅耳透镜55和凸透镜56的外周位于孔54a的外周之外。 The outer periphery of the outer periphery of the Fresnel lens 55 and the convex lens 56 is located outside the hole 54a.

此外,指针式仪表的速度表A布置在液晶面板53的后侧,因此刻度23、字符24、数字25和指针8的顶端部分可以在装饰板54之外被看见。 In addition, the speed of table A pointer instrument is disposed at a rear side of the liquid crystal panel 53, so the scale 23, the characters 24, 25 and the digital pointer tip portion 8 can be seen outside of the trim panel 54.

因此,驾驶员可以看见被孔54a的外周环绕的液晶面板53区域为由孔外周的虚像54ai环绕的虚像53i,虚像53i、54ai两者都从实际尺寸被放大。 Thus, the driver can see the area of ​​the liquid crystal panel 53 surrounded by the outer periphery of the hole 54a of the outer circumference of the virtual image 53i hole 54ai surrounding the virtual image, the virtual image 53i, 54ai is amplified from both actual size.

在一般车用显示设备中,液晶面板比指针式仪表在观察方向上更靠近观察者,因此液晶面板和指针式仪表彼此重叠而由此限制了它们之间的空间。 In a general vehicular display apparatus, the liquid crystal panel than the pointer instrument in the viewing direction closer to the viewer, the liquid crystal panel and therefore overlap each other pointer instruments thereby restricting the space therebetween. 所以,对于此受限空间需要使用小尺寸的液晶面板。 Therefore, for this limited space requires a small-sized liquid crystal panel. 结果,液晶面板上的显示图像变小而由此降低了液晶面板的可视性。 As a result, a display image becomes small thereby reducing the visibility of the liquid crystal panel on a liquid crystal panel.
