Abstract

A composite instrument panel having both an electronic display and an opaque dial plate is provided with features that mimic a seamless electronic display. The instant panel includes an electronic display and an applique having a translucent or transparent window through which the electronic display is viewable, and an opaque area adjacent the window defining a dial plate upon which indicia can be printed, the transparent or translucent window having a peripheral border area that transitions from transparent or translucent at an inner edge of the border nearer a center of the window to opaque or nearly opaque at an outer edge of the border farther from the center of the window.

Claims

1. An instrument panel display comprising: an electronic display; and an applique having a translucent or transparent window through which the electronic display is viewable, and an opaque area adjacent the window defining a dial plate upon which indicia can be printed, the transparent or translucent window having a peripheral border area that transitions from transparent or translucent at an inner edge of the border nearer a center of the window to opaque or nearly opaque at an outer edge of the border farther from the center of the window.

2. The instrument panel display of claim 1, wherein the peripheral border has gradient printing.

3. The instrument panel display of claim 1, wherein the electronic display presents graphic images at the peripheral border that fade from bright at the inner edge of the border to faint at the outer edge of the border.

4. The instrument panel display of claim 1, wherein the window of the applique is optically bonded to the underlying electronic display by an optically clear material disposed and filling a space between the window and the electronic display.

5. The instrument panel display of claim 1, further comprising a clear matte overcoat on at least the window.

6. An instrument panel display comprising: an electronic display; an applique having a transparent or translucent window through which the electronic display is viewable; and an optically clear material disposed and filling a space between the window and the electronic display to optically bond the window of the applique to the electronic display.

7. The instrument panel display of claim 6, further comprising a clear matte overcoat on at least the window.

8. The instrument panel display of claim 6, wherein the peripheral border has gradient printing.

9. An instrument panel display comprising: an electronic display; an applique having a transparent or translucent window through which the electronic display is viewable; and wherein the electronic display presents graphic images at the peripheral border that fade from bright at the inner edge of the border to faint at the outer edge of the border.

10. The instrument panel display of claim 9, wherein the window of the applique is optically bonded to the underlying electronic display by an optically clear material disposed and filling a space between the window and the electronic display.

11. The instrument panel display of claim 9, further comprising a clear matte overcoat on at least the window.

DESCRIPTION OF THE ILLUSTRATED EMBODIMENT(S)

(8) An instrument panel display 10 in accordance with this disclosure is schematically illustrated in cross-section in FIG. 2. The display includes an electronic display device 12, such as an LED display or an LCD (e.g., thin-film-transistor liquid crystal display), which can be mounted on a printed circuit board 14, and an applique 16 having a transparent (light transmissive without image distortion) or translucent (light transmissive with slight distortion, i.e., semi-transparent) window 18 and opaque dial plate portions 20, 22. Window 18 is disposed directly over (i.e., overlies) electronic display 12 to allow graphic content on display 12 to be viewed through the applique. Indicia can be provided on dial plate portions 20, 22, such as markings used in conjunction with a pointer to indicate oil pressure, fuel gauge readings, tachometer readings, etc.

(9) As shown in FIGS. 3 and 4, window 18 includes a peripheral border 26 that transitions from transparent or translucent at an inner edge 28 of the border nearer a center 30 of the window to opaque or nearly opaque at an outer edge 32 of the border farther from the center of the window. The transition can be achieved by gradient printing of the border. Gradient printing can for example be achieved by printing a pattern of dots wherein the dots become gradually larger in a direction to transition from clear to opaque or near opaque. The gradient or transition at the border 26 helps conceal the boundary between the window 30 and the dial plates 20, 22.

(10) The electronic display can be provided with a graphics generator or processor that produces a graphic image 40 at the peripheral border of the overlying window that fades from bright at the inner edge of the border to faint (or dim) at the outer edge of the border (see FIGS. 5-7). The fading effect can overlap the gradient printing at border 26 to achieve a seamless display with the electronic display ON (powered).

(11) With reference to FIG. 2, applique 16 can be optically bound to electronic display 12 by filling a space between window 18 and display 12 with an optically clear material 45. The image of display 12 is transposed onto the surface of applique 16 by material 45 because there is no significant change of medium (or refractive index) between the display and applique. As a consequence, display readability in sunlight is improved due to reduced reflection at the display surface, and image brightness is increased due to higher light efficiency.

(12) FIG. 7 is a schematic cross-section of a portion of the display at the border 26 of window 18. The gradient printing at border 26 overlies the portion of the electronic display 12 providing a fade effect for graphic 40, and a matte finish overcoat 50 is applied to the surface of window 18 (including border 26) to further help achieve a full seamless display appearance. Overcoat 50 can be applied by using ink printing techniques. The diffusion level of the ink is selected to achieve minimal loss of clarity of the displayed graphics.

(13) Accordingly, it is to be understood that the above description is intended to be illustrative and not restrictive. Many embodiments and applications other than the examples provided would be apparent upon reading the above description. The scope of the invention should be determined with reference to the appended claims along with the full scope of equivalents to which such claims are entitled. It is anticipated and intended that future developments will occur, and that the disclosed systems and methods will be incorporated into such future embodiments. In summary, it should be understood that the invention is capable of modification and variation.
