Description

Technical Field

[0001] This utility model relates to vehicle display technology, and more particularly to a wood grain-look cover and a vehicle display device. Background Technology

[0002] As cars become increasingly electrified and intelligent, the size of the center console display screen is getting larger and larger. Some cars with a business-oriented style use wood grain trim to make the center console. However, the display screen appears black or gray when not in use, which leads to an appearance inconsistency between the center console display screen and the wood grain trim. Utility Model Content

[0003] To address the shortcomings of the existing technology, this utility model provides a wood-grain-like cover plate with a wood-grain-like effect.

[0004] This utility model also provides a vehicle display device, including the aforementioned wood grain cover plate.

[0005] The technical problem to be solved by this utility model is achieved through the following technical solution:

[0006] A wood-grain-look cover plate, comprising:

[0007] Glass cover;

[0008] Wood grain-like ink is applied to the back of the glass cover, including a visible area and a peripheral area. The peripheral area surrounds the visible area, and the visible area is provided with an array of light-transmitting holes to create a semi-transparent effect.

[0009] Furthermore, the aperture of the light-transmitting aperture array is between 0.015 and 0.040 mm.

[0010] Furthermore, the aperture density of the light-transmitting aperture array is 200-500 apertures / mm. 2 between.

[0011] Furthermore, the light-transmitting hole array adopts circular holes or regular hexagonal holes.

[0012] Furthermore, the light-transmitting hole array is fabricated using laser engraving or photolithography.

[0013] Furthermore, the thickness of the wood grain-like ink is 5-10 μm.

[0014] Furthermore, the wood grain imitation ink includes at least a red ink pattern, a green ink pattern, and a blue ink pattern arranged in sequence.

[0015] Furthermore, the wood grain-look cover also includes:

[0016] The reverse-cover ink is applied to the back of the wood grain ink and only covers the outer perimeter area, while avoiding the visible area.

[0017] Furthermore, the glass cover is made of tempered glass with a thickness between 4.1 and 4.0 mm.

[0018] An in-vehicle display device includes a display screen and the aforementioned wood grain cover plate, wherein the display screen is attached to the back of the wood grain cover plate and corresponds to the visible area of ​​the wood grain ink.

[0019] This utility model has the following beneficial effects: The wood grain cover of this utility model achieves a wood grain effect by setting the wood grain ink on the back of the glass cover, and the array of light-transmitting holes is made on the visible area of ​​the display screen corresponding to the wood grain ink to allow some display light to pass through. When the display screen is lit, the visible area of ​​the wood grain ink allows some display light from the display screen to pass through, thereby providing a display image to the user. When the display screen is turned off, the visible area of ​​the wood grain ink provides a wood grain appearance to the user through the part covered by ink outside the holes, thus forming an appearance consistent with the wood grain decorative panel of the center console.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] Example 1

[0028] like Figure 1 and 2 As shown, a wood-grain-look cover includes:

[0029] Glass cover plate 31;

[0030] Wood grain ink 32 is applied to the back of the glass cover plate 31 and includes a visible area 321 and an outer area 322. The outer area 322 surrounds the visible area 321, and the visible area 321 is provided with an array of light-transmitting holes 323 to form a semi-transparent effect.

[0031] The wood grain cover of this utility model achieves a wood grain effect by applying wood grain ink 32 to the back of the glass cover 31. A light-transmitting hole array 323 is formed on the wood grain ink 32 in the visible area 321 of the display screen to allow some display light to pass through. When the display screen is lit, the visible area 321 of the wood grain ink 32 allows some display light to pass through, thus providing a display image to the user. When the display screen is turned off, the visible area 321 of the wood grain ink 32 provides a wood grain appearance to the user through the ink-covered portion outside the holes, thus creating an appearance consistent with the wood grain decorative panel of the center console.

[0032] To balance light transmission and wood grain appearance, preferably, the aperture of the light-transmitting hole array 323 is between 0.015 and 0.040 mm, and the hole density is between 200 and 500 holes / mm. 2 The transmittance of the visible area 321 is between 30% and 60%.

[0033] The light-transmitting aperture array 323 can be fabricated using laser engraving or photolithography. When fabricated using laser engraving, the aperture diameter of the light-transmitting aperture array 323 is between 0.020 and 0.040 mm, and the aperture density is between 200 and 400 apertures / mm. 2 When fabricated using photolithography, the aperture of the light-transmitting aperture array 323 is between 0.015 and 0.030 mm, and the aperture density is between 300 and 500 apertures / mm. 2 between.

[0034] The light-transmitting aperture array 323 can be circular or hexagonal. Compared to traditional circular apertures, using hexagonal apertures in the light-transmitting aperture array 323 can increase the aperture density by approximately 15% while maintaining the same aperture spacing.

[0035] In this embodiment, the wood grain imitation ink 32 has a thickness of 5-10 μm and includes at least a red ink pattern, a green ink pattern and a blue ink pattern stacked sequentially.

[0036] The wood grain imitation ink 32 is based on the principle of subtractive color mixing and adopts a layered printing method. The red ink pattern, green ink pattern and blue ink pattern are printed sequentially on the back of the glass cover plate 31 so that the red ink pattern, green ink pattern and blue ink pattern are superimposed to present a wood grain imitation pattern.

[0037] Specifically, the desired wood grain pattern is first drawn in drawing software and saved as an image. Then, the saved wood grain pattern image is imported into image processing software for analysis. The image processing software separates the wood grain pattern into corresponding red, green, and blue layers, and saves them as images respectively. Next, the images of the red, green, and blue layers are imported into a screen printing device to create screen printing stencils for the corresponding layers. Finally, red ink, green ink, and blue ink are printed sequentially onto the back of the glass cover 31 using the corresponding layer screen printing stencils to form the red ink pattern, green ink pattern, and blue ink pattern respectively.

[0038] Of course, to achieve a better wood grain effect, an additional layer of white ink can be added to the wood grain ink 32 as a base color layer.

[0039] Preferably, the wood grain cover plate further includes:

[0040] The reverse-cover ink 33 is disposed on the back of the wood grain ink 32 and only covers the outer perimeter area 322, while avoiding the visible area 321.

[0041] The reverse-cover ink 33 is preferably black ink or gray semi-transparent ink, to cover the outer area 322 of the wood grain imitation ink 32.

[0042] Preferably, the glass cover 31 is tempered glass with a thickness between 4.1 and 4.0 mm.

[0043] Example 2

[0044] like Figure 3 As shown, an in-vehicle display device includes a display screen 1 and a wood grain cover plate 3 as described in Embodiment 1. The display screen 1 is attached to the back of the wood grain cover plate 3 and corresponds to the visible area 321 of the wood grain ink 32.

[0045] Preferably, the display screen 1 is fully bonded to the back of the wood grain cover plate 3 using OCA optical adhesive 2.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them. Although the present utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present utility model, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the scope of the technical solutions of the present utility model.
