Description

Technical Field

[0001] The present application relates to the technical field of vehicle-mounted screens, and in particular to an anti-peep cover for a vehicle-mounted screen and a vehicle-mounted screen. Background Art

[0002] The anti-peeping effect of the in-vehicle screen is the mainstream display configuration in the current automobile market. For example, the left and right anti-peeping function can prevent the screen display from being reflected on the left and right side glass when driving at night, so as not to affect driving. The upper and lower anti-peeping function can prevent the screen display from being reflected on the front windshield when driving at night, so as to avoid affecting driving and improve the safety factor and driving experience at night. The existing anti-peeping function of the in-vehicle screen is integrated inside the backlight. The backlight is responsible for providing light source for the screen. Due to the requirements of the night driving environment, in order to improve the driving safety factor and driving experience, the screen needs to have an anti-peeping function when driving at night.

[0003] Integrating the anti-peeping function of the car screen into the backlight requires reserving the thickness of the anti-peeping film inside the backlight, which increases the overall thickness of the backlight and thus the thickness of the entire screen. In addition, such an anti-peeping film will reduce the brightness of the screen by 15%-20%. In order to meet the brightness design requirements of the entire screen, it is necessary to increase the number of LEDs inside the backlight or the number of prism films inside the backlight, which will result in excessive power consumption of the entire screen, high heat dissipation requirements, and high costs, making it difficult to meet the needs of users.

[0032] like Figures 1 to 3 As shown, according to a first aspect of the utility model, a privacy cover for a vehicle-mounted screen is provided, and the privacy cover for a vehicle-mounted screen comprises a glass layer 1, a privacy film 2 and a coating portion.

[0033] In the following description, reference will be made to Figures 1 to 3 The specific structure of the above components of the anti-peep cover for the vehicle screen and the connection relationship of the above components are specifically described.

[0034] like Figures 1 to 3 As shown, in an embodiment, a transparent glass layer 1 can be used to cover the upper part of the display screen of the vehicle-mounted screen. The privacy film 2 can cover the upper surface of the glass layer 1. The privacy film 2 is used to play an anti-peeping function, that is, to prevent the image displayed on the vehicle-mounted screen from being reflected on the windshield of the vehicle. The coating portion can be further arranged on the upper part of the privacy film 2 to enhance the use effect of the privacy cover for the vehicle-mounted screen (such as anti-fingerprint). Such a setting can improve the driving effect and driving experience of passengers without increasing the cost, power consumption and thickness of the whole machine, so that the thickness of the vehicle-mounted screen is relatively thin, the power consumption is reduced and the cost can be optimized.

[0035] Preferably, Figures 1 to 4 As shown, in an embodiment, the coating portion may include an anti-fingerprint coating 3. The anti-fingerprint coating 3 (i.e., AF layer) may be a hydrophobic and oleophobic material layer coated on the surface of the substrate. The anti-fingerprint coating 3 can effectively resist fingerprints, and it is not easy to leave fingerprints after the operator's finger touches the anti-peep cover for the vehicle screen, and even if sweat or other stains are left, it is easier to remove. The anti-fingerprint coating 3 can be arranged on the upper part of the anti-peep film 2.

[0036] Preferably, Figure 4 As shown, in the first embodiment, the coating portion may only include the anti-fingerprint coating 3. The anti-fingerprint coating 3 is directly coated on the upper part of the anti-peep film 2.

[0037] Preferably, Figure 1 and Figure 3 As shown, in an embodiment, the coating portion may further include an anti-reflection coating 4. The anti-reflection coating 4 (i.e., AR layer) uses the light wave theory. When light is secondary reflected on the anti-reflection coating 4, the secondary reflected light can interfere with the original reflected light to reduce the reflected light. The anti-reflection coating 4 can be disposed on the upper part of the anti-peep film 2.

[0038] Preferably, Figure 3 As shown, in the second embodiment, the coating portion may only include an anti-fingerprint coating 3 and an anti-reflection coating 4. The anti-reflection coating 4 may be disposed between the anti-peep film 2 and the anti-fingerprint coating 3, that is, the anti-fingerprint coating 3, the anti-reflection coating 4 and the anti-peep film 2 are disposed sequentially from top to bottom. Specifically, the anti-fingerprint coating 3 may be evaporated on the surface of the anti-reflection coating 4.

[0039] Preferably, Figure 1 and Figure 2 As shown, in an embodiment, the coating portion may further include an anti-glare coating 5. The anti-glare coating 5 (i.e., AG layer) may be a frosted surface on the surface of the privacy film 2, which is used to convert the incident light from specular reflection to diffuse reflection, prevent the image from directly reflecting the object to the human eye, and enable the user to see the information displayed on the screen more clearly. The anti-glare coating 5 may be disposed on the upper part of the privacy film 2.

[0040] Preferably, Figure 2 As shown, in the third embodiment, the coating portion may only include the anti-fingerprint coating 3 and the anti-glare coating 5. The anti-glare coating 5 may be disposed between the anti-peep film 2 and the anti-fingerprint coating 3, that is, the anti-glare coating 5, the anti-reflection coating 4 and the anti-peep film 2 are disposed sequentially from top to bottom. The anti-glare coating 5 may be formed by spraying AG solution on the surface of the anti-peep film 2.

[0041] In addition, preferably, Figure 1As shown, in the fourth embodiment, the coating portion may include an anti-fingerprint coating 3, an anti-reflective coating 4 and an anti-glare coating 5. The anti-fingerprint coating 3, the anti-reflective coating 4 and the anti-glare coating 5 may be arranged on the upper part of the anti-peep film 2 in sequence from top to bottom. A spraying process may be used to spray AG solution on the surface of the anti-peep film 2 to form an anti-glare coating 5. Then, a vapor deposition process is used to vapor-deposit surface treatment AR on the surface of the anti-glare coating 5 to form an anti-reflective coating 4. Finally, a vapor deposition process is used to vapor-deposit surface treatment AF on the surface of the anti-reflective coating 4 to form an anti-fingerprint coating 3.

[0042] Preferably, Figures 1 to 4 As shown, in the embodiment, the lower surface of the privacy film 2 may be provided with glue, and the privacy film 2 may be glued to the upper surface of the glass layer 1. Such a setting may allow the privacy film 2 to be used as an explosion-proof film substrate (the explosion-proof film refers to a film material hardening layer that buffers impacts to prevent glass from splashing out after bursting and causing injury. When the glass breaks, the explosion-proof film can effectively adhere to the glass fragments, and the surface of the explosion-proof film is still smooth when touched), providing an anti-peep function for the vehicle screen while achieving the effect of an explosion-proof film.

[0043] Preferably, Figures 1 to 4 As shown, in an embodiment, the anti-peep cover for the vehicle screen may further include a glue layer 6. The glue layer 6 may be disposed at the lower portion of the glass layer 1, and the glass layer 1 may be bonded to the display screen of the vehicle screen through the glue layer 6. Preferably, the glue layer 6 may be made of OCA optical glue.

[0044] In addition, preferably, Figures 1 to 4 As shown, in an embodiment, the thickness of the glass layer 1 may be 1.1 mm to 1.8 mm. The thickness of the anti-peep film 2 may be 0.1 mm-0.2 mm. The thickness of the anti-fingerprint coating 3 may be 0.001 mm-0.002 mm. The thickness of the anti-reflective coating 4 may be 0.001 mm-0.002 mm. The thickness of the anti-glare coating 5 may be 0.001 mm-0.002 mm. The thickness of the glue layer 6 may be 0.25 mm-0.75 mm. Such a setting can make the anti-peep cover for the vehicle screen play a better effect.

[0045] During use, the peep-proof cover plate for the vehicle screen adopts a laminated structure, with the peep-proof film 2 as the explosion-proof film substrate, and AR, AF, and AG surface treatments are performed on the surface of the peep-proof film 2 to achieve explosion-proof and peep-proof effects. This reduces the thickness of the internal peep-proof film of the backlight (the backlight acts as a light source in the vehicle screen), thereby reducing the thickness of the backlight, effectively solving the technical problems of the vehicle screen being thick, high cost, and high heat dissipation requirements for the entire display screen.

[0046] In addition, according to the second aspect of the utility model, a vehicle screen is provided, the vehicle screen includes a display screen and the above-mentioned anti-peep cover for the vehicle screen, the anti-peep cover for the vehicle screen can be pasted and covered on the display screen of the vehicle screen. In this way, the thickness of the instrument, central control and co-pilot entertainment screen in the vehicle screen can be beautifully designed, and power consumption and cost can be reduced, which greatly improves the effectiveness and cost-effectiveness of the design.

[0047] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them. The protection scope of the present application is not limited thereto. Although the present application is described in detail with reference to the above-described embodiments, ordinary technicians in the field should understand that any technician familiar with the technical field can still modify the technical solutions recorded in the above-described embodiments within the technical scope disclosed in the present application, or can easily think of changes, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should be included in the protection scope of the present application.
