An ITO pattern layer is arranged on the upper surface of the array substrate, an ultraviolet filter film is arranged on the lower surface of the color film substrate, and a BM layer and an RGB pixel layer are arranged on the lower surface of the ultraviolet filter film. Due to the fact that the ultraviolet filtering film is arranged on the lower surface of the color film substrate, when external light enters the surface of the liquid crystal display, the ultraviolet portion with high energy can be absorbed or reflected out by the ultraviolet filtering film, ultraviolet rays cannot enter a liquid crystal box, and therefore photosensitive components such as liquid crystals and thin film transistors (TFT) in the liquid crystal box are prevented from being affected by strong light. And the problems of color consistency change, screen flash and the like of the display screen are avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display, and more specifically to a liquid crystal display screen which is free from the influence of strong light. Background Art

[0002] The structure of the liquid crystal display is to place a liquid crystal box between two parallel glass substrates, set TFT (thin film transistor) and other circuits on the array substrate glass, and set a color filter on the color film substrate glass. The signal and voltage on the array substrate TFT are changed to control the rotation direction of the liquid crystal molecules in the pixel area, thereby controlling whether the polarized light of each pixel point is emitted or not to achieve the display purpose.

[0003] The color filter substrate CF is mainly composed of R, G, B color resistors, PS and BM. BM is used to block the wiring and TFT component area between the pixels of the array substrate so that light cannot pass through.

[0004] The array substrate is mainly composed of TFT devices and circuit traces of each layer. The liquid crystal in the pixel area between the color filter substrate and the array substrate is controlled, and the non-pixel area is blocked by the color filter and BM, so that the liquid crystal display screen can display the required picture in a controlled manner.

[0005] With the gradual promotion of domestic mobile phones in low-latitude areas such as Africa in recent years, regional specific environments such as strong external light have gradually become key considerations in the research and development and production of mobile phone displays.

[0006] Because liquid crystal and TFT devices are optical effect components, their working characteristics will be affected to a certain extent under the irradiation of continuous strong external light, thus causing problems such as changes in the color consistency of the display and screen flickering. Utility Model Content

[0027] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0028] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships 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 referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0029] In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", and "third" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0030] The utility model provides a liquid crystal display screen which is protected from strong light, comprising an array substrate and a color film substrate, wherein the color film substrate is arranged above the array substrate, a frame glue and a liquid crystal are arranged between the array substrate and the color film substrate, the liquid crystal is arranged in a space enclosed by the frame glue, an ITO pattern layer is arranged on the upper surface of the array substrate, an ultraviolet filter film is arranged on the lower surface of the color film substrate, and a BM layer and an RGB pixel layer are arranged on the lower surface of the ultraviolet filter film.

[0031] Since a UV filter is provided on the lower surface of the color film substrate, when external light enters the surface of the liquid crystal display, the ultraviolet light with higher energy will be absorbed or reflected by the UV filter, preventing the ultraviolet light from entering the liquid crystal box, thereby protecting the photosensitive components such as liquid crystal and TFT in the liquid crystal box from the influence of strong light, avoiding problems such as changes in the color consistency of the display and screen flicker.

[0032] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. The present invention is described in detail below in conjunction with the accompanying drawings and embodiments, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention.

[0033] See also Figure 1, a liquid crystal display screen that is protected from strong light provided by the utility model, comprises an array substrate 1 and a color filter substrate 2, the color filter substrate 2 is arranged above the array substrate 1, a frame glue and liquid crystal are arranged between the array substrate 1 and the color filter substrate 2, the frame glue is coated on the outer edge of the glass substrate, the liquid crystal is poured into the space enclosed by the frame glue, an ITO pattern layer is arranged on the upper surface of the array substrate 1, an ultraviolet filter film 21 is arranged on the lower surface of the color filter substrate 2, and a BM layer 22 and an RGB pixel layer 23 are arranged on the lower surface of the ultraviolet filter film 21. Since the ultraviolet filter film 21 is arranged on the lower surface of the color filter substrate 2, when external light enters the surface of the liquid crystal display, the ultraviolet part with higher energy will be absorbed or reflected by the ultraviolet filter film, so that the ultraviolet light cannot enter the liquid crystal box, thereby protecting the photosensitive components such as the liquid crystal and TFT in the liquid crystal box from being affected by strong light, and avoiding problems such as color consistency change and screen flicker of the display screen.

[0034] The ultraviolet filter film 21 is usually made of a special material that can selectively absorb or reflect ultraviolet rays. The structure of the ultraviolet filter film 21 generally consists of two parts: a substrate and a filter layer. The substrate is the supporting structure of the filter, and in this case, the color film substrate 2 serves as the substrate. The filter layer contains special compounds or pigments that can selectively absorb or reflect ultraviolet rays of a specific wavelength. The filter layer materials include zinc oxide, titanium dioxide, etc., which can be made by vacuum coating process.

[0035] See also Figure 2 As a further optimization scheme of Example 1, in this embodiment, an upper polarizer 3 is provided on the upper surface of the color film substrate 2, a cover plate 4 is provided above the upper polarizer 3, an anti-fall plate 5 is provided above the cover plate 4, an ink layer 51 is provided on the lower surface of the anti-fall plate 5 located in the non-visible area, and the cover plate 4 and the anti-fall plate 5 are fixed by an adhesive layer 52, and the adhesive layer 52 completely covers the ink layer 51 and the lower surface of the anti-fall plate 5. Since there is an anti-fall plate 5 on the cover plate 4, and the adhesive layer 52 is printed entirely on the back of the anti-fall plate 5, it covers the ink layer 51 in the non-visible area and the lower surface of the anti-fall plate 5 in the visible area, fills the ink step difference, and does not cause the phenomenon of laminating bubbles and edge yellow spots. The cover plate 4 can be fully laminated with the upper polarizer 3 through the optical glue 6. Since the cover plate 4 is not provided with the ink layer 51, it will not cause the phenomenon of laminating bubbles and edge yellow spots, thereby avoiding the display abnormality of the liquid crystal display module, thereby reducing the probability of defective products in the liquid crystal display module, and greatly reducing the production and manufacturing costs of the liquid crystal display module.

[0036] And when the anti-fall plate 5 is impacted by external force, the anti-fall plate 5 will break first. Due to the buffering effect of the adhesive layer 52, the cover plate 4 is not easy to break, so the cover plate 4 and the main screen can be well protected. When the anti-fall plate 5 is broken, the anti-fall plate 5 can be easily peeled off, and only a new anti-fall plate 5 needs to be replaced. There is no need to replace the entire LCD display module, thereby greatly reducing the maintenance cost of the LCD display module, thereby improving the product competitiveness of the LCD display module, thereby meeting the company's growing quality requirements.

[0037] Further, the thickness of the ink layer 51 is 8 μm to 15 μm.

[0038] Furthermore, the thickness of the adhesive layer 52 is 50 μm.

[0039] Furthermore, the thickness of the anti-fall plate 5 is 5 mm to 10 mm, and the thickness of the cover plate 4 is 3 mm to 5 mm.

[0040] Furthermore, the upper surface of the anti-fall plate 5 is covered with an anti-fingerprint film layer to prevent user fingerprints from remaining on the anti-fall plate 5 and enhance the aesthetics.

[0041] Furthermore, a color conversion layer is provided on the upper surface of the anti-fingerprint film layer located in the non-display area to further enhance the aesthetics of the product.

[0042] Furthermore, the hardness of the anti-fall plate 5 is greater than the hardness of the cover plate 4 to enhance the protection effect.

[0043] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] Obviously, the embodiments described above are only some embodiments of the present application, rather than all embodiments. The preferred embodiments of the present application are given in the accompanying drawings, but they do not limit the patent scope of the present application. The present application can be implemented in many different forms.
