Anti-peeping TFT display screen and electronic equipment

Abstract

This invention provides a privacy-protecting TFT display screen and electronic device. The privacy-protecting TFT display screen includes a display structure layer, which comprises, from bottom to top, a lower glass layer, a liquid crystal layer, a color filter, a privacy layer, and an upper glass layer. The privacy layer is used to achieve privacy protection for the display screen. In this invention, by setting a privacy layer inside the display structure layer of the TFT display screen, the privacy protection effect of the product is improved, which is beneficial to protecting user privacy. It eliminates the need to apply a privacy film to the cover plate, avoiding the problems of poor edge adhesion, easy dust ingress, and even lifting or falling off of traditional privacy films. This is especially beneficial for displays with a rounded perimeter structure, improving the quality and privacy protection effect of the TFT display screen.

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0025] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix", "set" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] First, see Figure 1 The embodiment of the utility model provides an anti-peeping TFT display screen, including: a display structure layer 100, wherein the display structure layer 100 includes a lower glass 110, a liquid crystal layer 120, a color filter 130, an anti-peeping layer 140 and an upper glass 150 arranged in sequence from bottom to top, and the anti-peeping layer 140 is used to realize the anti-peeping of the display screen.

[0027] In the utility model, an anti-peeping layer is arranged inside the display structure layer of the TFT display screen, thereby improving the anti-peeping effect of the product, which is beneficial to protecting the privacy of the user. There is no need to stick an anti-peeping film on the flat surface of the cover plate, thereby avoiding the poor edge adhesion of the traditional anti-peeping film, easy dust ingress and even warping and falling off, etc., especially for a display screen with a circular arc structure on all sides, thereby improving the quality and anti-peeping effect of the TFT display screen.

[0028] As a preferred embodiment of the present invention, the anti-peeping layer is arranged on the lower surface of the upper glass by sputtering or evaporation.

[0029] As a preferred implementation of the present invention, the thickness of the anti-peep layer is 0.05 mm.

[0030] The surface of the privacy layer set by the above method is relatively thin and flat, so it can be set inside the display structure layer, sputtered or evaporated on the lower surface of the upper glass, and then the color filter is set. Since the privacy layer is added inside the display structure layer, it can prevent the privacy layer from being damaged.

[0031] As a preferred embodiment of the present invention, please refer to Figure 2-3 The display structure layer 100 further includes a lower polarizer 160 , and the lower polarizer 160 is disposed under the lower glass 110 .

[0032] As a preferred embodiment of the present invention, please refer to Figure 2 The display structure layer 100 further includes an upper polarizer 170 , and the upper polarizer 170 is disposed on the upper layer of glass 150 .

[0033] As a preferred embodiment of the present invention, please refer to Figure 3 The anti-peeping layer 140 is an anti-peeping polarizing integrated film layer, which is used to realize the anti-peeping and upper polarization of the display screen. Therefore, the TFT liquid crystal display can form an image only by relying on the lower polarizer 160 and the anti-peeping layer 140.

[0034] The upper and lower polarizers are polarized light sheets, and the imaging of the TFT liquid crystal display must rely on the lower polarizer and the upper polarizer. By setting the anti-peeping layer as an anti-peeping polarized light integrated film layer, the anti-peeping of the display screen can be achieved, and the structure of the upper polarizer can be omitted, saving costs and reducing the thickness of the display screen.

[0035] As a preferred embodiment of the present invention, please refer to Figure 4 The anti-peeping TFT display screen of the embodiment of the utility model further includes a backlight module 200, and the backlight module 200 is arranged below the display structure layer 100. The backlight module is used to provide a backlight source for the display screen.

[0036] As a preferred embodiment of the present invention, please refer to Figure 4 The anti-peeping TFT display screen of the embodiment of the utility model further includes a cover plate 300, which is arranged above the display structure layer 100. The cover plate 300 is an arc-shaped structure around, which not only improves the touch of the edge of the TFT display screen, but also reduces the risk of the corner of the display screen being knocked and broken.

[0037] As a preferred implementation of the present invention, the cover plate 300 and the display structure layer 100 are bonded together by OCA optical adhesive.

[0038] In a second aspect, the utility model further provides an electronic device, comprising an anti-peeping TFT display screen as in any embodiment of the utility model.

[0039] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
